CHAPTER 2- LITERATURE REVIEW Introduction Literature review in the present study presents the scholarly material available on the chosen subject matter. The present review provides synthesis of literature on various aspects related to the chosen topic of role of BIM in construction. The review has been conducted in the form of themes. The first theme provides an account of literature about concept of BIM. This is followed by the second theme which comprises of the role of BIM in construction. The third themeprovidesanaccountofpreviousliteratureonthechallengesassociatedwith implementation of BIM in construction. The literature search has been conducted by using key search terms. Various databases have been searched for obtaining relevant literature on the chosen topic. Recent and updated journal articles have been included in the review. Concept of BIM (Building Information Modeling) According to Borrmann and et.al. (2018), BIM is a collaborative approach which is used for sharing, storing and management of multidisciplinary information that concerns with the life cycle of a building project. This takes into account the various aspects such as planning, design, maintenance, demolition, operation etc. The authors emphasize that BIM is a promising concept and has been found to be one of the most useful developments in fields of engineering, architecture and construction. The introduction of the concept took place a decade ago with the sole purpose of distinguishing between traditional 2D modelling and 3D modelling. López and et.al. (2018) informed that BIM mainly consists of information database technology and 3D modelling concepts. It also includes an interoperable software which can be used by contractors, architectsandengineersforpreparingthedesignofafacilityandcreatingasimulated construction. The study conducted by Matarneh and et.al. (2019) found that with BIM the various members of a project team are able to generate a virtual model of the building structure in a 3D format. The model of all the systems of the project structure can be created in 3D format and information can be shared with each other. It includes various details such as drawings, 8
specifications and other construction details which form the important part of the model. It further includes attributes such as quantity characteristics of building, its geometry, spatial relationships etc. with the help of these details, the design and construction issues can be identified by the project team. Following it, these can be resolved at the earlier stage before the construction phase starts. Matarneh and Hamed (2017) stated that BIM is a process using which building data is generated and managed during the lifecycle of the construction project. It makes use of 3D real time dynamic building software so that productivity can be enhanced in the design and construction of buildings. BIM technology creates an accurate virtual model of the building which not only contains the relevant data but also accurate geometry. This provides support to the various aspects such as fabrication, procurement and construction which are important for execution of the project. However, Teizer and et.al. (2017) believe that BIM is considered to be the foundation of digital transformation in the construction as well as engineering industry. This concept uses an intelligent model which is enabled by a cloud program. Through this, it facilitates integration of data for digitally representing an asset throughout the various phases of its life cycle. But, Ghaffarianhoseini and et.al. (2017) argue that BIM is different from 3D CAD modeling. Although both these processes are involved in providing geometric expressions of the buildings as well as infrastructure. But, BIM is not limited to this. It goes one step ahead and captures metadata, relationships and those behaviors which form an intrinsic component of the real world building structures. Nawari (2018) explored the various standards that internationally define the structures and processes of BIM. ISO 16739-1:2018 is concerned with the industry foundation classes (IFC) for data sharing in the construction industries. Internationally, the BIM processes are defined by the ISO 19650 series of standards. According to Borrmann and et.al. (2018), a BIM object contains detailed information that provides definition about a product. It also contains the geometry which indicates the physical characteristics of the product. The BIM objects can be of two types, component and layered. Component objects are those building products which are characterized by presence of a fixed geometric shape. In contrast to this, layered objectives are those that do have a fixed shape. These may include components such as roofing, walls and ceilings. Matarneh and et.al. (2019) 9
stated that specifications are also an important part of the BIM process. For designing the built asset requirements need to be specified. This is dependent on the required performance outcome. Further, it is also necessary to update the specifications throughout the construction phase. Matarneh and Hamed (2017) explored the concept of BIM dimensions. This can be considered to be a part of the modelling evolution which comprises of moving from drawing boards to 2D CAD and then to 3D modelling. The 4D is called as ‘modelling scheduling information to model construction sequences’. The 5D is the dimension which is concerned with adding financial cost. 2D BIM comprises of a geometric model that constitutes an X and Y axis. As compared to this, 3D BIM is the digital geometric model which comprises of X, Y and Z axis. This model provides more details at different levels. Further, it is also possible to combine multiple 3D models which could provide useful information about presence of any geometric clashes. The role of BIM in construction As perAhankoob, Manley and et.al., (2019), the major role of BIM in construction plays an important role in addressing to the usage of how effectively and in significant manner BIM is valuable in the construction. One of the major role which BIM addresses in the construction is in delivering the sustainable building value which is being done by the quality of the performance displayed by the building to solve the problems which is arising by the consumers, owners, developers, building users. This is done in the constraints of time and cost displayed for the project undertaken. To deliver the sustainable building value, there are certain decisions which are made during the designing of the stages of constructing the building. This designing is done by choosing the building systems, integrating it with the outdoor conditions and considering the reliability, durability and flexibility at large scale. The delivery of this value requires effective and integrated process of delivery process within the construction at large scale. According toBosch-Sijtsem and Gluch, (2021), as part of the requirements delivering sustainable building value within the role of BIM in construction, the performance mandates occur within the factors of being acceptable and reliable. The major aspects of sustainability building value in the construction includes smart building systems, fire safety, building structural stability, resource efficiency, earthquake resistance etc. Lower design and construction costs are the determinants of building the value within the construction. This helps in addressing as to how 10

the role of BIM is performed within construction and this helps in analyzing the aspects of building and constructing it in the operations of the function as to the design and framework of the building. By making and framing the designs of the building which proves to be of sustainable value helps in understanding that the role of BIM in construction is displayed in an effective and efficient manner. As denoted byMordue and Finch, (2019), the second major role which BIM plays in the construction is that it allows the architects to predict the potential construction hazards and helps them to prevent the designs which are framed at large scale. This will enable the architects or the builders to analyze the aspects of considering the positive and negative effects which enable the designing and framing of the building and removing the hazards on the construction sites so that the designs can be framed correctly and accurately. The contractors also lead their teams safely at every step by meeting the regulations and following the steps which enables the construction process to run smoothly and in effective manner. The designing and framing of the structure of the building is done with the help of BIM in construction playing its role in an effective and efficient manner. According toLindblad and Guerrero,(2020), therefore, the two main roles which BIM in construction plays is – delivering the sustainable building value and allowing the architects to predict the potential construction hazards which is helping them to prevent the designs framed at large scale. These two major roles help in addressing that how effectively and in appropriate manner the development of the building is done by designing and reflecting on the growth and development of the structure framed. This is the major aspects as to how the role of BIM in construction is displayed. The architects and the contractors are in for the information which keeps the information and knowledge for how the development of the building and the construction along with its layout is to be done. This has been a major consideration of keeping all the details in the final position of having the basis of creating a factor by delivering the role of BIM in the construction. Zhang, Chong and et.al., (2022), the role of construction has not only created value for the basis of BIM but has also evaluated and has significantly drawn the significance of delivering positive value in this different field of knowledge. The major role is in construction which has been displayed and is keeping with the knowledge of addressing the basis of designs, layouts 11
which are framed before the building when constructed properly and in appropriate manner. Various hazards are also removed which are becoming the hindrance while construction of the building. This displays the major role in which all aspects of growth and development in this field. As denoted byNguyen and et.al., (2020), 3D technology and 2D designs helps in addressing the aspects as to how effectively the projects are framed in such designs are created for the construction of the building. The project performance of the organization is also improved by using BIM in construction. The dimensional aspects of the project are being addressed and are taken into consideration at large scale with the implementation of how the project outlining and structure is framed at large scale within the construction industry. Nawaz, Su and Nasir, (2021), BIM in construction plays the major role in establishing work performance of the construction players at large scale and addresses the aspects of how the BIM in construction is done and how skillfully the architects, construction players are devising their roles and standards while working within the construction industry are serving the best within the structure of implementing the work related performance of construction players. The performance of the construction players helps in addressing to the aspects of growth and development within the construction industry and how effectively and in appropriate manner the changes and modifications within the performance are done. This is the major role of BIM in construction due to which the performance of construction players is encouraged and they are motivated to perform better for their roles and achieving certain responsibilities. As depicted by (), BIM enables the construction project to visualize the construction which is framed virtual at large scale. This enables the project to be completed within the timeframe which has been allocated and is devised according to the plan of construction. Another major role as stated byJacobsson and Merschbrock, (2018), is that BIM in construction plays the major role in lowering carbon emissions during construction. This helps in defining the architects and contractors to analyze exact quantities of building materials which is required in the project at large scale. There is estimation of the budget which is related to pre bid and end budget which helps in making reduction in the material waste which can be achieved. This impacts resources, energy and travel time to obtain building materials which is helping to lowering down the carbon emission. 12
The role of BIM in construction as stated byAlizadeh Salehi and Yitmen, (2018), has very major role in communication process which enables better communication for the project which has been undertaken and helps in analyzing the aspects as to how effectively and in appropriate manner the communication between the partners is made very clear and enables the aspects of understanding the major responsibilities within the project when it is started. For BIM, all modifications such as timings, availability of materials and schedules are managed and are communicated within the structure of having clear communication between the partners and shareholders which has been addressed and is about to take the completion stage of the project. Rathnasinghe, Kulatunga and et.al., (2020), Information and data within the BIM in construction helps in acknowledging the aspects of growth and development which has been analyzed at large scale. The role of BIM in construction helps in addressing the major points as to how the changes and modification within the construction industry is done accordingly. Easy access to cloud services for the construction industry helps in addressing that how effectively and in appropriate manner the information is gathered and the plans are devised within the project to be undertaken at large scale. Therefore, these are the major roles which BIM displays within construction industry and helps in addressing how effectively the details and information is gathered. The significance of BIM in construction plays major role in devising how the projects are undertaken are creating value for the purpose of significant delivery of project. Challenges in relation with implementation of BIM in construction AccordingtoHasanandRasheed,(2019),therearemajorchallengeswhile implementation of BIM in construction which helps in providing the aspects as to what are the challenges which are being faced. Some major challenges which the BIM in construction faces are – Lack of expertise, lack of awareness, resistance to change, lack of cooperation between shareholders, cost effectiveness for projects which are small in the construction of the BIM. These are some of the major challenges which are faced while implementation of BIM in construction. Due to lack of expertise the building of the construction through BIM is done properly and the contractors or architects may find it difficult to attain the position of how the construction is done. As perMoses, Heesom and et.al., (2020), the next major challenge while implementing BIM in construction is cost effectiveness for projects which are managed and maintained for the 13

small projects creates difficulties which creates difficulties in the BIM in construction. This is how the challenges are faced in knowing the aspects of BIM in construction. Also, lack of cooperation between the shareholders becomes a challenge while implementing the BIM in construction. The major problems are faced and the value of the project which has been undertaken is disturbed when the challenges occur in the construction of the building. Moreover, this is how the challenge is being drawn upon and how effectively the implementation should be done so that there are no difficulties and problems which are being faced when BIM in construction is analyzed and evaluated. Therefore, this is the best analysis that the company is able to effectively analyze and create value for coping up with the challenges and creating effective analysis within the structure of building the project. The challenges should be faced in an appropriate manner. As denoted byUmar, (2021), the legal issues in implementation of BIM in construction also becomes one of the major challenge which creates problems in the issuing and agreement which is made by the clients. There is incompatibility of procurement systems with BIM. There is liability of project participants which arises due to the error in design, misuse or error in the data, risk allocation in the transferring of the data becomes the major issue within the legal system. And within the legal issues the major challenge while implementation in BIM in construction helps in addressing that there may be copyright and insurance on the reliance issues which are addressed and are considered at large scale. When these issues are addressed within the system of how negatively and in challenging manner BIM in construction is affected, there are aspects which are created and are addressed at large scale. These are some legal issues which creates disturbance while implementation of BIM in construction. As perAbd Jamil and Fathi, (2018), BIM requires number of parties for example architects, contractors, engineers and supply chain members which makes the problem of how the implementation of BIM in construction is done. The training of staff members and the business developers are in the stage of how there are negative effects which are being created and this is the major reason as to how the architects, contractors are involved in the aspects of growth and development to be done. Training of staff becomes the major challenge while building of the project as more number of expertise are required during the period of the project 14
being undergoing but due to lack of knowledge and understanding of the project there are less number of individuals which are to be engaged within the project. Alazmeh, Underwood and Coates, (2018), states that modelling of the software for the project of BIM in construction becomes the major challenge as the construction or changes requires substantial investment in the software with powerful PC and huge data amount which is to be used and analyzed at large scale. This is the major challenge which is being faced by the construction industry. There are also aspects as to how this challenge can be removed and smoothly the BIM in construction industry becomes the most effective and efficient process which is being undertaken. The huge amount of data which is required in the aspect of BIM in construction for collecting the details is understandable but when there are certain challenges which are faced by the construction industry, it makes the aspects of growth and development more in the difficult manner and is them not solved at large scale. Shirowzhan, Sepasgozar and et.al., (2020), denotes that incompatibility with partners becomes challenging in the BIM in construction and this creates conflicts and problems between the partners and the individuals who are involved in the BIM project to be completed effectively and in scalable manner. The incompatibility and issues which are not between the partners affects the project and creates disturbances in the relationships of the individuals. This is how there are difficulties which are denoted and are creating the aspects of difficulties in the manner as to how different changes and modifications are done in manner to address and solve the issues and challenges faced within BIM in construction. According toAyman, Alwan and et.al., (2020), the next major challenge which the BIM in construction faces is lack of experts in the field of BIM in construction. This makes the project on going and processing difficult within the system of how the project is to be undertaken. While constructing the BIM there are negative aspects which are being addressed and this is how the changes and modifications are analyzed at large scale. 15
CHAPTER-3 RESEARCH METHODOLOGY Introduction The research methodology of the present study is concerned with the appropriate form of research that has been adopted for conducting the research. The specific reason behind selecting the research methods has been highlighted. Major attributes that are highlighted under this are, Research type, research approach, research philosophy, research design, data collection, data sampling and data analysis. The research type is concerned with the procedure of performing the research.Researchapproachdeterminedthesystematicapproachesofresearch,Research philosophy is based on the beliefs that has been put by researcher while conducting research. Furthermore, data collection describes the procedure of gathering facts and figures in order to reveal the outcomes of research. Lastly, the data analysis determines the interpretation of the collected data so, the outcomes can be review. Research type Research type refers to the systematic procedure of gathering facts and figures in order to conduct the research. It is an important attribute in terms of conducting the research. Also, it has been considered as the first step of starting the research process as the data has been collected under this. In order to reveal the research outcomes it is highly important to collect facts and figures that helps in revealing the results. The major source of gathering the facts has been deprived within selecting research type. Therefore, it is important to select the appropriate research type that can assure effective result at the hand. Mainly, the research type has been considered of two types and that is qualitative and quantitative research type. The qualitative research type refers to the gathering of textual data. The facts that has been gathered under qualitative type is deprived from theories. In involves deep understanding of the data that has been gathered. Often, the relevancy of the data is higher under this as the gathered data is in the form of theories (Weaver-Hightower, 2018).Also, it enables researcher to seek the depth of the research. The textual or theoretical data reveals opinion in relation of the research topic therefore, it creates the better understanding for the researcher. The only thing that is needed to assure a keen focus while collecting the data is concerned with collection of data from the original sources. 16

On the other hand, quantitative research type is aligned with the collection of data in numerical terms. The statistical figure has been revealed in context of this research type. Thus, this research type is not aligned with making any opinion within collecting the data as it is concerned with acquiring numerical figures. The data that has been collected in this clearly shows the numbers that reveals the outcomes of the research. The advantage of quantitative type is that, it is highly easy to understand as only the numerical terms needs to be seen in terms of reveling outcomes. However, the major disadvantage of this research is concerned with the errors in writing down the figures. If the figures that has been written wrong then, it provides the direct impact over the outcomes of the research. Wrong interpretation will be revealed in the research. As per the suitability of current research the researcher has used the qualitative type of research in terms of collecting data. The facts have been gathered in terms of textual and theoretical form. The major reason behind using the qualitative type of data is that, it assures higher relevancy in the context of research topic. Furthermore, this is enabling researcher to seek the depth of research as the data that has been gathered under this is aligned of opinions that enables to know the pros and cons of a particular topic and helps in stating the points that reveals final outcomes. Therefore, the researcher is using the qualitative research type so, the higher relevancy can be assured in the outcomes and the results generate higher efficiency. Research approach Research approach has been considered as the concept that divides the whole procedure of research in different steps in order to perform the research steps in effective manner. As conducting the research involves numerous steps that is aligned with the numerous parameters therefore, it is highly important to arrange all those parameters in systematic manner so, the effective outcomes can be produce. In case, the research approach has not been performed within conducting the research then, it provides direct impact over the final outcomes of the research therefore, systematic research approach is needed to be adopted so, all the steps can be reviewed in proper manner. The research approach is mainly of three types and those are, Inductive, Deductive and Abductive. The inductive research approach refers to that approach that is comprises-of collecting the data that is related to the interest of the topic. Mainly, the new theory has been developed under inductive approach. This approach enable researcher to make a deep observation over the research topic and on the basis of that, new theories has been revealed. Furthermore, the development of new theory enables researcher to identify the procedure of 17
research in context of new theories. Whereas, the deductive approach is based on the establishing of research process on the basis of the existing theory. It does not provide chance to researcher in terms of examining the research from all parameters. Often, there is no development of new theories has been take place. Thus, in this approach the research has been carries out within studying existing theories and the observation has been made and limited outcomes has been revealed. Deductive approach is based on the scientific investigation that deprived-from the existing theory. It is important to evaluating the research from all aspects. Deductive approach does not assure this opportunity in context of conducting research. The Abductive research approach stats with the creation of puzzles and then, the research procedure explains the major concept that has been highlighted in the puzzles. The major limitation of this approach is that it does not provide opportunity for using divergent thinking to the researcher in terms of revealing the outcomes of the research. For this research, the researcher has adopted the Inductive research approach as this approach assuring the room of opportunities to analyst in order to develop new theories that can help in revealing the final outcomes. Furthermore, this approach is assuring the numerous benefits to the research study. This approach allow flexibility to the researcher in terms of carrying out the procedure of research. Thus, the changes can be easily adopted and applied. The major benefit of this theory is entitled with the development of new and fresh theories that can be used in making assumption regarding future in context of research topic. Thus, within using inductive research approach under this research, the analyst has become able in relation of generating new theories that in increasing the scope of research. Furthermore, it is helping in interpreting the final outcomes in effective manner that reveals new concept in relation of research topic. Research philosophy Research philosophy has been determined as the faith and belief of the people living in society in relation of the research topic. It has been considered as the one of the most important attribute as it involves the thoughts and opinion of individuals in context of research topic. The research philosophy makes able analyst in terms of understanding the thought process of the people and then, on the basis of that final opinion has been made that helps in revealing final outcomes. It helps in developing the major ideas that are related to enhancing the outcomes of research. The research philosophies have been mainly parted into three parts and those are, 18
Interpretivism, positivism and realism. Interpretivism philosophy refers to the that philosophy that is concerned with the belief that social world can be understand on the basis of the subjective manner. Every individual is consisting of different opinion in society. Interpretivism approach helps in gathering the information of research within understanding the faiths and beliefs of the people living in society. This philosophy is aligned with understanding the values of people in relation of the research topic. It is important to understand the values and belief of the people as helps in shaping the final outcomes. The results that is concerned with the values and beliefs of the people in context of research topic assures higher effectiveness. Positivism philosophy deprives from the scientific faith and beliefs, this philosophy is concerned with the motive of understanding the scientific opinion and comes over the final decision (Hales, 2021).It provides limited scope in terms of understanding the opinion of the society. The analysis under this philosophy are highly unrealistic and based on the scientific approach. No changes can be made over this. Thus, Positivism philosophy creates limited scope for researcher. Realism philosophy is concerned with the realistic facts in relation of the research topic. This philosophy does not provide space in terms of understanding the values and opinion of the people. The society in consist of numerous people that are consists of large number of thoughts. Realism philosophy is based on the one-time decision that has been made and consider that decision or opinion as realistic. However, it is important to identify the different opinion of the people that are living in the society as this helps in reviewing their faith and belief with respect of research topic.

Theme2: BIM is the standard framework of success BIM is directly linked with the success in construction industry. Often, it has been determined as the standard framework of success in construction. It has often considered as the critical success factor in construction. The success rate of the project is determined with its effectiveness and the effectiveness of project is aligned with the focus and dedication that has been made over each attribute of project. Thus, BIM enables contractors to provides a keen focus over specific parameters and when all factors has been critically identified and managed then, it creates direct impact over the success rate. Thus, in similar manner, BIM is associated with the potential of determining success in construction. BIM creates the understanding in users in context of having clear information regarding the materials, systems and physical structure. Thus, this sets the standards in terms of performing the task. Often, it creates mandatory framework that develops effective understanding in relation of 3D elements that clear the vision and mission of the project. Furthermore, quality assurance has been ensured by the BIM in construction. Thus, the quality directly indicates the standards. Thus, in this manner BIM sets higher standards rate for performing task. Theme3: Challenges in BIM can be easily managed with implementation of efficient strategies The outcomes of the research evaluated that, challenges tin BIM that act as a barrier can be easily managed with the implementation of effective practices. The major focus needs to be assure over the experience of the client as it provides idea about the structure that has to be made within using BIM. On the basis of that, final practices should be performed. Furthermore, at the time of implementing BIM the work needs to be carried out in slow manner as creating rush can impact the whole process and creates difficulties in managing situations and hurdles. Analytical tools can be used as effective tools that helps in analyzing potential risk at the site. Thus, the challenges in BIM can be easily managed within implantation of pre-planned strategies. Also, expert needs to be appointed as they have higher knowledge in terms of solving the issues that are arriving in the implementation of BIM. Thus, challenges in implementation of BIM works as a barrier however, it does not completely hinder the success rate of the project. The barriers and challenges can be easily managed with selecting the appropriate strategies. 23
Theme4: BIM supports the physical, financial and human resources in construction Architectures and contractors uses BIM in construction as it helps in creating the effective base in context of performing project activities. Findings of research revealed that, BIM helps in selecting the physical resources within creating structure in digitalized mode. Major physical resources that are required for the project has been planned with the help of BIM. On the basis of that, the physical resources have been finalized at the sites. Furthermore, Financial resources has also been determined with the help of BIM (Nguyen, Dung and Hanh, 2021).The cost has been assumed within considering the structures and physical resources that has been finalized in the project. Moreover, BIM creates effective team collaboration among the members thatareworkingonsite.Thus,BIMsupportshumanresourceinconstructionaswell. Coordination and communication among team members has been improved with the help of BIM. Theme5: BIM mitigates risk The outcomes revealed that, BIM leads to mitigate risk. As the planning regarding the physical injuries that can be faced by the workers at site has been pre-noticed. On the basis of that, the risk strategies have been prepared that assures effective contribution in management of risk at site (Erpay and Sertyesilisik, 2021).Thus, BIM performs fundamental priority in context of saving human force at the site. Moreover, the project related risk has also been solved by BIM. The planning clears vision in minds what needs to be done and what should not. Theme6: BIM supports sustainability and asset management BIM helps in preparing virtual building models before the implementation of actual practices. Thus, the documents and construction process has been designed with the help of BIM. Therefore, the environmental aspects can be taken in consideration before starting of the actual project. BIM enables in making visualization in relation of project. Therefore, using such materials or sources that makes drastic impact over environment has been easily identified with the help of BIM.BIM promotes the knowledge assessment and it further leads to maintain the concept of sustainability and asset management. Thus, along with assuring success rate in project the ethical aspects have also been covered by BIM. 24
Thus, the above major findings are clearly stating that, BIM is construction plays major role in terms of performing the major parameters. BIM is aligned with focusing over all resources in equal manner and enhances the capability of work in construction. Thus, within involving BIM in construction higher standards can be set and managed as well.

standard framework in terms of performing the task and assures effective results at the end of construction project. The major benefit of BIM is associated with its multi-disciplinary approach. Also, it helps in making effective collaboration (Hasan and Rasheed, 2019).However, the effective rate of performing activities in context of BIM states the rate of effective onsite collaboration. Implementation of BIM creates effective opportunities in terms of experiencing cost savings over the project. Furthermore, it helps in making effective decisions. Moreover, the most sustainable option can be adopted with the help of BIM. It has been found from various studiesthat,BIMhasbeenproveneffectiveenoughintermsofimprovingtheonsite coordination and communication. Thus, onsite effective communication among the member provides assurance of effective deliverables of the project in construction. Also, the cost that has been determined in the project is based on the models that has been selected for the project. Thus, the major benefits of BIM concerned with the increasing the coordination on the site along with assuring cost-effectiveness (Manzoor and Othman, 2021).The productivity plays vital role asitdeterminestheeffectivenessoftheconstructionproject.Theassuranceofhigher productivity has been given by the BIM. Within using BIM, the entire project can be easily planned and visualized before starting of the actual project. Thus, it creates effective base in context of starting and implementing actual project. The 3D visualization has been performed with the help of BIM and this creates the clear structure for the clients as well. The scenario of preconstruction has been highly supported with the help of BIM. The studies have evaluated that, clash that begins before the construction can be easily resolved with the help of BIM (Siebelink, Voordijk and Adriaanse, 2018).Automated clash detection feature of BIM enables contractors and engineers in terms of solving the clashes that can act as a barrier in the construction process. Thus, here it has been clearly depicts that, BIM is the backbone of construction. The effectiveness of project is aligned with BIM. It assures opportunities in order to make plans before the actual practices takes place. Also, the dynamics that arrived frequently can be managed with the help of BIM. Thus, BIM helps in managing uncertainties as well. Further research evaluation have shown that, safety is one of the fundamental priority at the sites as it is associated with the lives of the workers who are working at the site. BIM plays mandatory role in terms of improving construction safety at the site. Within pinpointing the 26
major hazards the physical risk towards the workers can be easily reduced. Also, the precautions have been determined that helps in reducing the physical risk. The visualization of the risk has been done with the help of BIM and then, planning has been performed so, the risk can be managed. Thus, the BIM has been proven highly efficient from all aspects whether it is about planning the activities at the site or ensuring safety to workers (Adhikari, Meadati and Baek, 2020).Furthermore, the effective focus has been assured over the environmental aspects with the help of BIM. Moreover, it helps in increasing the efficiency of communication at the site. Thus, BIM focuses on all attributes and ensures effective results. Therefore, it has been proven highly important in construction as it is aligned with the effective technologies that leads to ensure efficiency in the project. Also, the records can be easily managed with the help of BIM. BIM sets high rate of standards and supports best practices in construction BIM is a standard set that offers the platform in terms of presenting digital representation of the physical along with the functional features of a facility. Studies have evaluated that, BIM creates the standard format in construction industry that helps in performing the task within maintaining standard format. Also, the quality assurance in the making of building has been provided by the BIM. Thus, the set standards of BIM initiates the best practices and it further helps in delivering potential outputs. The 3D model creates establish high set of standards that derives from the working pattern of construction. As a result, at the time of performing actual procedure the standards has been taken in consideration and the practice has been performed. Thus, BIM creates opportunities in terms of assuring higher standards in the projects (Carvalho, Bragança and Mateus, 2021).If the quality of the project has not been maintained then, there is no sense of delivering the final output. In construction industry major element of BIM is aligned with managing standards and using the high standards in actual practices. Thus, it supports in implementing and supporting effective practices in construction. It has been found from various studies that, in BIM there are mainly four levels that has assures the contribution in setting high standards for project. BIM level 0 is associated with presenting the information in relation of building modelling. However, at this stage the information that has been presented is concerned with the initial level and no coordination among the parties has been made at this stage. The paperwork has been done at this level and initial drawings related to building model has been prepared and idea has been gathered. 27
In BIM Level 1 the data has been changed into a specific form of structure. Here at this level the structure related to building modelling has been made in 3D visuals. However, at this stage also no collaboration or coordination has been made among the parties. BIM Level 2 performs the fundamental elements of starting the project. Under this level, the planning, designing and construction cycle has been prepared and coordination among the parties has been made. At this level, the data has been shared, gathered and stored within using the single source ofdata.Here,mainlytheassetmanagementisperformedwiththehelpofknowledge management (Olawumi and Chan, 2019).The data has been prepared has used whenever there is requirement. BIM Level 3, the meetings and collaboration with the clients and stakeholders has been done and the gathered data is discussed with them and then the practices has been started. Thus, BIM creates the set of standards in different level that helps in performing and planning task in steps. Also, BIM acts as support system in performing final practices. Furthermore, it helps in setting standards with help of designing structural system of the building also, the related elements such as, electricity, roof structure, site work, plumbing and so on elements has been managed with the help of BIM. Implementation of planning within using BIM indicates the capital requirement for the project. In such manner, from initial stage the budget requirement has been cleared. As a result, no complexities has been faced while performing actual practices. The site conditions has been determined with the help of BIM. The requirements of the site depend upon the size of project. Thus, BIM helps in maintaining the condition of site as well. The major practices need to be performed over sites therefore, it is highly important to focus over the requirements of sites as well. It has been found from various studies that, BIM performs important role in team collaborationatthesite(ArashpourandWakefield,2020).Teammanagementhasbeen considered as one of the most important aspect in terms of managing the standards also, it helps in assuring the effective practices. When the work has been carried out within managing effective team collaboration then, it provides assurance of success rate in work. Thus, BIM helps in managing effective interaction among the workers, contractors and sub-contractors. As a result, effective flow of information takes place among them and the errors has been identified in fast manner. Thus, BIM sets high standards furthermore, helps in managing the standards. Moreover, act as a support system in implementation of best and effective practices. 28

Challenges in BIM can be manage with effective strategies There are large number of challenges has been faced in the implementation of BIM. These challenges are concerned with lack of expertise, dynamics at site, lack of cooperation among the stakeholders and lack of awareness in relation of using BIM. Thus, there is no doubt that, BIM is associated with the major challenges that may act as barrier in implementation of BIM. Often, this challenges can impact the final deliverables of the project. BIM act as a support system in construction industry. Therefore, challenges in BIM can impact the procedure pf work. Lack of expertise refers to that challenge in which the members who handles concept of BIM are concerned with lack of knowledge (Tchouanguem Djuedja and et.al., 2019).In such situation, the implementation of BIM does not perform in productive manner and it impacts the practices of construction. in order to resolve this challenge, the experts needs to be appoint so, the implementation can be done in effective manner. Numerous changes have been take place at the site and this provide influence over the decision and the planning that has been made at initial stage within using BIM. This can impact over-all working procedure. Therefore, it is highly important that, while making planning, the assumptions and premises has to be develop for future as well. In case, the changes take place then, the pre-planned strategies help in facing challenges. Thus, the issues that comes in the implementation of BIM can be easily solve with the help of making effective plans at initial stage. It has been found from, various studies that, lack of awareness is relation of using BIM impacts the working procedure at site in negative manner. In order to ensure higher effectiveness in work it is highly important that, complete knowledge in relation of using and implementing BIM is needed. Therefore, the proper knowledge needs to be acquired and afterwards the implementation has to be performed. So, the issues cannot be derived at the time of establishing the practices. Furthermore, the discussion needs to made with the client in relation of the structures that has been visualized (Kamel and Memari, 2019).It helps in having idea related to the satisfaction level of client and on the basis of that further activities can be implemented. Lack of cooperation among the stakeholders directly impacts the practices at the sites. Therefore, it is highly important that, meetings needs to be session and each information and piece of data that has been gathered within using BIM has to be share with the stakeholders. Also, the coordination and cooperation among stakeholder needs to be maintained. The challenges in BIM needs to be manage within making effective strategies at starting. Thus, this results in solving the issues that 29
are coming in the implementation of BIM. However, if the focus has not been assured from initial stage then, it leads to impact the over-all working procedure. On the other hand, if the focus have been ensured through initial stage then, it leads to create the base in relation of solving issues. BIM and Resource allocation in construction BIM is directly linked with the resource allocation in construction industry, whether the resources are human, financial of physical. BIM plays vital role in allocation of resources in effective manner. Without allocating resources it is hard to perform practices in construction. Therefore, BIM performs mandatory role in resource allocation. The physical resources at the site has been allocated with the help of making structure within using BIM. On the basis of that, the idea in relation of capital management has been gained. Thus, BIM helps in allocation of financial resource along with physical resource. The visualization in relation of building model has been made with the help of BIM and then, whatever physical resources that are required in order to perform function has been pre-planned. Thus, the pre-planning related to the allocation of physical resources clears scenario in mind (Piroozfar and et.al., 2019).Also, the contractors can easily set budget plan that is aligned with performance of task. Financial resources play crucial role in terms of determining the success rate of project. In order to arrange finance it is important to have knowledge in relation of the areas and the rate of cost that is required. Thus, BIM clears this confusion in mind and helps in making plans in relation of allocating finance for performing actual practices. Thus, BIM has been proven effective in terms of analyzing the budget requirement in making of building and on the basis of the evaluation the plan has been established. Thus, the physical and financial resources can be arranged in effective manner within implementation of BIM. Human resource refers to the set of humans that has been acquired in terms of performing task at the site. BIM contributes effective focus over management of the human resource as well. BIM implementation assures effective cooperation and coordination among stakeholders and members. When the effective cooperation has been ensured then, it provides the assurance of potential results. Thus, along with managing physical and financial resource BIM focuses over management of human resource as well. Also, the safety measures towards the workers at the site has been performed with the help of BIM. Thus, BIM enables in managing the safety of 30
humans as well at the site. The major hazards that can assure harm to the workers has been identified within pointing them with the help of BIM. Afterwards, the measures has been taken in relation of the harms of risk that can cause physical harm to the workers at the site. Also, BIM helps in determining the precautions that helps in creating safe environment at the workplace. It clearly states that, BIM helps in assuring safety to the workers at site (Osorio-Sandoval, 2021). Hence, the human safety at the site has been performed with the help of BIM. Thus, allocation of physical, financial, human resources has been easily managed with the implementation of BIM. BIM performs effective contribution in context of resource allocation. Thus, it creates supportive base in terms of performing construction activities in effective manner. BIM is a tool of technology that plays vital role in reducing risk Technology has been determined as one of the most crucial element in all sectors, technology makes the work procedure easy in every field. In similar manner, findings revealed that, BIM is that tool of technology in construction that manages all complexities and ensures higher effectiveness. If BIM has not been used then, most of the project remains incomplete and it further affects work procedure of the industry. Thus, BIM has been determined as the mandatorytooloftechnology.Mainly,exchangeofinformationhasbeendonewithin implementing BIM. Information that has been exchange with the help of BIM sets the base for making and developing major plans that can assure success in the projects. Furthermore, the effective communication has been established with the help of BIM. Communication plays crucial role in determining the success rate of project (Stransky and Dlask, 2018).Therefore, it is highly important that, communication must be done in effective manner that provides assurance of success. Thus, BIM provides the technological platform on which effective communication among the members at site can take place. Thus, the results states that, BIM is the tool of technology that helps in performing mandatory parameters related to performing communication and managing activities. The Outcomes have shown that, BIM helps in reducing the risk often, it leads to mitigate the risk as well. Most of the companies have adopted the concept of BIM and this has resulted in assuring them effective success. The BIM initiate the close coordination with the contractors that provides the assurance of reducing the tender risk (Mellado and Lou, 2020).Also, the it reduces 31

the insurance cost. The better overview of the project can be generated with the help of BIM. It has been defined as the construction technology that helps in implementation of effective technology in the construction. As technology has become highly important in all areas and when it comes to construction. It plays crucial role in delivering effective outcomes. Thus, BIM hasbeenprovenhighlyeffectiveintermsofinvolvingtechnologyinconstruction.The constructionschedulingsetbackshasbeenimprovedwiththehelpofBIM.Themajor documentation that are required can be manage within using BIM. Thus, it often helps in managing the records as well. The new information can be easily included in the documents and the records can be easily managed with the help of BIM. On the basis of available information, the task and activities has been scheduled in relation of project. Hence, scheduling construction activities at the site is often based on BIM (Noor and Yi, 2018). The data that has been gathered in BIM is used for generating the drawings, designs and database in context of manufacturing purpose. The proper planning with the help of in relation of manufacturing process leads to develop the effective opportunities in terms of maintaining the environmental aspects as well. The strategies related to the elimination of waste and using the renewable form of energy can be implemented with the help of BIM. Thus, it helps in taking environmental concern decision. BIM performs ethical concerns within assuring sustainability It has been found from various studies that, using BIM can lead to manage waste at the site. Furthermore, it helps in performing sustainable operations as well. Within using BIM, architecture creates the design and structure of building. The major focus has been assured towards managing the resources in effective manner. So, the concept of sustainability can be performed in effective manner. Currently, the concept of green building has become highly important. The standard framework in context of green building has been designed by the higher authorities. Therefore, the sustainable method of designing the building needs to be followed. Also, this leads to save from certain legal penalties by government (Ayman, Alwan and McIntyre, 2020).Thus, BIM plays major part in green building projects. BIM has been used in order to reduce energy consumption and the major impact of the building over the environment has been managed within this. Also, BIM provides specific modelling tips architecture that can use is context of performing the concept of green building.Currently, green architecture has become highly mandatory in construction. As saving environment has become the major priority. Therefore, certain aspects need to be followed by construction industry. Otherwise, it impacts the 32
project in drastic manner. If the environment concern has not been shown by the construction sector. Then, heavy penalties have been posed over them. Even, the projects needs to be stopped in such situation. Thus, BIM is boosting-up the level of projects within assuring the effective feature of managing environmental aspects. The major factors that provides contribution in making building green are concerned with the materials that has been selected in terms of performing operations. Thus, the material selection needs to be done in such manner that does not provide harm to environment. Furthermore, helps in saving up the resources of future as well. BIM enables managers in terms of selecting those places in terms of constructing building that are far from the local areas. So, the harm does not assure to the people as well from the activities of construction. Landscape and Centric design has been done in such manner that does not perform depletion of soil. Thus, in this manner the natural resources have been saved within using BIM. BIM regulates the process and progress of the construction site (Uddin and et.al., 2021).Also, energy that has been used in the process of construction activities has been used in such manner that assures the energy consumption. Thus, BIM has been proven extremely reliable in terms of performing the green practices along with delivering efficient results. As BIM assures clarity at every stage therefore, it is easy for the engineers in terms of focusing over the concept of sustainability. Also, it helps in reducing waste at construction site that contributes in protecting environment. As the waste generation needs to be settle down in environment and this creates negative impact over environment. Therefore, implementation of BIM is highly required in terms of managing sustainability and assuring green practices. Thus, BIM is linked with the concept of sustainability. 33
Chapter 6: CONCLUSION AND RECOMMENDATIONS From the research it can be concluded that, BIM has been proven highly effective in terms of assuring its effective contribution in construction industry. From initial level to end it plays crucial role in supporting each task and activities. Often, it helps in managing hurdles in well- defined manner. Along with this, risk can mitigate with the help of BIM. Effective coordination and cooperation can be maintained among the members at the site. Thus, it helps in assuring effective and potential deliverables at the end of the project. Pre-construction planning can be easily performed with the help of BIM. It enables the architecture and engineers in terms of making plans and designs before implementation of the actual practices. Furthermore, BIM sets high standards in construction industry and supports the best practices as BIM helps in pre- planning everything. Also, it helps in managing the coordination and communication among the members. Therefore, standards framework in relation of work has been created with the establishment of BIM. Moreover, BIM helps in managing the quality of project throughout the project period. Any error that has been occur while completion of project then it can be easily verify with the help of BIM. BIM supports the effective practices and often assures effective results. However, there are numerous challenges that has been faced within implementation of BIM. The major things that needs to be assure focus in associated with effective understanding of using BIM. Thus, effective understanding in this context helps in managing the threats that comes in the implementation of BIM in construction. also, discussion regarding the project needs to be done with the client so the proper idea can have in relation of the designs that needs to be used within the project. Along with this, proper discussion and planning has to be done with the team members as it plays vital role in supporting the plans (Altaf and et.al., 2020).Another major attribute that has been performed by BIM is entitled with the allocation of resources in construction industry. Allocation of resources is highly important as it is mandatory for carrying out the process. Thus, BIM helps in making plan in relation of physical resource that are needed in construction. On the basis of this, financial resource has been determined. Also, on the basis of planning the number of workers is hired. Hence, in this manner BIM enable in selecting the appropriate resources along with their acquirement. 34

Thus, within implementation of BIM, construction industries can improve their working pattern. As a result, final impact will be made over the deliverables of project. Therefore, BIM has been proven highly effective in context of assuring best practices (Lu, Lai and Tse, 2018).Furthermore, BIM is just not limited to making effective contribution in best practices. Along with this it supports the green practices as well. Currently, concept of green building has become highly important as it promotes the concept of sustainability. Thus, BIM helps in analyzing best method in relation of performing sustainability practices. On the basis of that most appropriate practices have been selected that ensures higher rate of sustainability. Thus, it can be said that BIM is the backbone of construction industry. It is enabling industry in terms of performing The major recommendation over using BIM is concerned with- Developing BIM roadmap in effective manner. It helps in making clear structure that can be easily understand by all members that are performing their activities. The designs that has been selected within using BIM must be communicated with the client so the proper idea in context of client preference can be taken. The 3D visualization of BIM is highly mandatory as it helps in understanding whole procedure in effective manner. Therefore, within implementation of BIM it is highly mandatory that, 3D visualization needs to be done (Awwad, Shibani and Ghostin, 2020).Also, experts need to be hire as they are aware about the concept and usage of BIM. Random person who does not have experience cannot use BIM in effective manner. Thus, large number of challenges has been faced in such situation. Therefore, experts should to be hire. Conformance over the requirements is one of the mandatory task that has to be done within BIM. It assures numerus options to the architecture and engineers and often creates confusion. Many-times those options has been selectedthatarenotappropriate.Therefore,theoptionsmustbeselectedafterassuring conformance to the requirements. The effective manner of using BIM initiated with the ground floor. Afterwards, team needs to be assemble and discussion should be done in context of the planning, design and activities. Effective discussion should be taken in consideration and afterwards document must be progress. The experts should monitor the whole process as they are highly experience. There are large numerous challenges that are aligned with the implementation of BIM. However, 35
focusing over these challenges from initial stage helps in managing the situations and hurdles. Therefore, it is highly important to decide strategies in the planning part. Providing keen focus from starting helps in managing the hurdles and barriers that can come in the working procedure. Often, it helps in verifying small barriers as well. Thus, BIM is a leading technology tool that ensureseffectivecontributioninmanagingtheactivitiesofconstructionalongwith implementation of efficient team management. Thus, it clearly concludes that, construction industries should use BIM in context of developing effective buildings. This will enable industries to perform environmental concern as well (Olugboyega and et.al., 2020).BIM is linked with the green practices. Therefore, assurance of sustainability can be given within using BIM. Also, BIM will enable construction industries in terms of reducing the risk that has been generated at the site. As the planning in relation of the potential risk has been made during the planning.
