INTODUCTION
Recycling is consider as part of environmental considerations, which has become common
feature that applicable in the construction industry. Concrete materials should consist of various
waste item but it require to the use for building, bridges and road construction (Oluwafemi and
et.al., 2019). Typically waste components which mainly include cement concrete, metal, plastic
and soil. Concrete recycling will help in construction project to reduce waste materials, trying to
keep site tidy and safe.
The civil engineer will face a lot of problem or issue in the construction projects, which are
both positive and negative way to impact on the entire construction project. therefore, it is
mainly focused on the recycling concrete applicable in construction project whereas how it will
affect on the different raw materials.
The report will discuss about the use of Recycling concrete technique or method for
reducing the waste during construction project. It will consider the risk identification and find
out the appropriate solution. The documentation is mainly focused on the identification of entire
project scope, include project management plan through Gantt chart, PERT technique for
providing the better solution.
TASK 1
Risk identification
The London construction contractor firm that are working with various concrete
construction project. Assistant manager of company is mainly focused on use concrete recycling
technique in the construction project. In order to keep tidy and safe construction site. Sometimes,
it is the most effective concept which help for organization to reuse concrete materials into
another construction project (Ganiron , 2015). There is no doubt when reduce waste within
concrete construction project, which help in the project development. In order to maintain the
environment sustainability. But it is not success for long-term so that it can be identified the
different problem or issue in recycling concrete process.
 The concrete rubble has potential of being contaminated by different materials. This type
of problem or issue should be consider when concrete incorporated into new. It is the
most common problem identified within construction sites (Oluwafemi and et.al., 2019).
3

 The use of concrete recycled is the mostly in low quality or strength. For example-
Pavement base and slab are basically used in the structure concrete. The commonly used
recycled concrete in the sub base within road construction. In this way, it would require
the bulk fills or materials for drainage structure. After the removal of contaminant
through demolition which automatically reduce the size in crusher to aggregate size.
Research methods
There are different type of method that mainly used to gather or collect lot of information
within construction project. It can be identified the problem of project in regards of concrete
recycled and then applied to better solution to eliminate problem. By using secondary analysis, it
can be collected or gathered information about recycled concrete in construction project through
books, journals and articles (Oikonomou, 2015 ). In this way, it can determine the way in which
encountered the problem or issue. From collected the information, it has been determined the
better sustainable construction and always keep safe, tidy sites. While implementing the
technique of recycled concrete that may reduce wastage of concrete materials, but it lower the
strength or quality.
Feasibility studies
The feasibility study is based on the process which mainly useful for identifying the
different areas of project. In order to eliminate or remove the problem within construction
project. In the construction, feasibility study may take place of different activities, helping the
concrete construction project to improve stability. There are different way to perform the
feasibility study on the construction project when it can be used the Recycled concrete materials
in other project.
The recycled concrete has gaining more interest in global world because of their
environmental, energy and economic considerations (Oluwafemi and et.al., 2019). When it is
properly implemented the concrete recycled constituent which carried the economic advantage,
benefits. In fact, it also helping to indicate as superior quality of strength, durability and fire
resistance.
In additional, it should be consider the suitable method to identify the feasibility study of
project in step by step manner.

Preliminary design: when starting the construction project, it always focused on the
identifying the initial layout, structure of project. Afterwards, it can be moved towards another
level. Otherwise, it has more chance to fail the project. It will be appropriate amount of
resources, equipment’s and cost expenditure. Preliminary design is consider as one of alternative
technique through which failure of project. In London construction contractor firm, manager
cannot determine the overall feasibility in term of design pattern.
Detailed design is another important approach for project which require to identify the
ineffective requirement of different problem, usually, it has been occurred in the different project
stages. Therefore, it has increased time scale and resources. Some of major problem can be
identified within overall design of project. In case, if it may not consider appropriate software
which has increased the complexities.
Afterwards, it becoming difficult to resolve at right time. It is important to design the
pattern so that it can easily maintain the stability as well as durability of project. Otherwise, it
directly impact on the entire project.
Project financing: it is another necessary aspect of project which can be finding the
accurate success and failure of project. it make a proper financial plan so that project manager
can handle the budget rising issue.
Project brief
The London construction contractor firm is mainly works on the concrete construction
project. it may require to consider the different factors which always support for improving the
quality, durability of project. Whenever the use of recycled concrete materials in project which
has increased the problem. Usually, it can be reduced the strength, stability of construction (Jie
and Nan, 2020).
On the other hand, it has rapidly reducing the use of natural resource and replacing it with
waste raw materials in order to avoid the problematic construction issue. When it can be used
recycled concrete which compressive strength is lower and its material high porosity, which
affecting on the durability, stability of material (Oluwafemi and et.al., 2019). The recycling of
construction project and other demolition waste are completely emerged with other concrete
materials.
5

In this way, Assistant manager is analysing the suitability of entire project whereas how it
will be resolving the certain issue in concrete recycling (Oluwafemi and et.al., 2019).
Afterwards, it also analysing the construction project and identifying associated problem due to
concrete recycled. In order to conduct the further resource planning, implement an effective raw
materials to construct the best quality of project.
Rationale
The primary reason of project is to understand the topic for project. Nowadays, London
construction contractor firm is mainly focused on use the concrete recycling within project. it
help for reducing the large amount of waste, keep maintain tidy or safe surface of sites. Another
way, it also applicable to maintain environment, economic sustainable. But in some cases, it has
been generated the problem low quality or strength. Afterwards, it has been implemented the
suitable solution to control the problem or issue during concrete construction project.
TASK 2
Identify the project scope with require the potential Resources, timescale and cost
The project scope is mainly depending on the different potential resource which always
support for identifying the overall project price, time intervals. Furthermore, it also considered an
effective plan which help for project to complete the task in proper manner.
 Cost: It can be identified the actual price/ cost which require to complete the project. The
project manager can be performed the specific task to calculate the price of project and
successfully completed (Chen and et.al., 2019). Initially, it may include price of all
resources such as machinery, manpower, issues. The overall project cost is £15,000.
 Resource: It is an essential part of project completion to consider an appropriate
resources. It mainly include hardware, software, raw material and workforce. These are
consider an important resources which help for resolving project issue or problem in
proper manner (Chen and et.al., 2019). On the other hand, Project manager always
concerned about the essential resources because it provide an easier process. Afterwards,
it can perform the different activities to complete the project effectively and efficiently.
 Time interval: It is also another important scope of project when it complete the project
on specific deadline. Project manager can understand the demand of project so as they
6

can complete the entire project in 2.5 months. Time scale is the best suitable approach
which always included in the project stages (Chen and et.al., 2019)*. It is helping for
completing the project on time. Every project has a specific deadline so that it always
used to complete task.
 Scope: The project scope is consider as an essential parameter that help for identifying all
resources such as time scale, price. On the other hand, another scope of project is to
understand the current condition of concrete recycling, identifying the problem to
implement appropriate solution in it.
Determine the range of technique for potential solution.
In above, it has identified the problem within recycled concrete and then afterwards, it
can be implementing the better solution to resolve problem. There are considered as an effective
solution that mainly used for protecting or securing.
The use of such waste as recycled aggregated in concrete which become useful for both
economic as well as environmental aspects in the construction company (Prošek and et.al.,
2020). But it can be replace the natural coarse aggregate through recycled concrete into structural
concrete.
As identified the most common issue or problem in regards of contamination. It is an
essential for implementing appropriate solution to eliminate this issue otherwise, it directly
affecting on the other materials which will be used on structure design.
One of the possible solution of this problem is to recycle construction and demolition
concrete waste. In order to produce as an alternative aggregate for specific structural concrete. It
has to done screening process then removal of contaminants such as gypsum, Reinforcement
item at construction sites. The concrete made with different type of recycled concrete aggregated
which is also known as RAC (Recycled aggregate concrete).
Another solution is that when improving the RAC properties, modify through mixing
process. it help for improving the behaviour of concrete (Rahman, Mohajerani and Giustozzi,
2020). According to mix design, it can easily maintain the use of various fine natural minerals
additives which may replace of adding other reducing agent or cement in water.

In additional, the overall price/ cost with directly associated with the project. it may
include the different activities or task. Therefore, it can be estimating the project £15,000 but it
would require to calculate the overall budget and project management plan to consider all
essential resources.
Prepare and update the ongoing project Management plan by using Gantt chart and PERT for
purpose of project evaluation
There are various type of technique or method used to track the activities of entire project
progress in step by step manner. The Method or techniques also considered the different task
which require to follow and completed in proper manner.
PERT Chart
It is based on the technique which mainly used for project evaluation or review in order
to identify the critical time intervals. Another words, it can be said that PERT chart provide the
better solution because it consists of different activities. in order to perform the task in step by
step manner.

Gantt chart
It is mainly representing the graphical chart of entire project schedule in step by step
manner. in order to show the interdependencies between multiple activities. It became consider
as useful for representing start date to end date of construction project. Moreover, project
manager always consider this technique to identify all essential tasks.
9

The Gantt chart is mainly representing the task, preprocessor, duration, start and end time.
These are considered as essential for project completion because each one contain apporpriate
unique process. It helpo for generating the appropriate desirable result or outcome (Kerzner,
2019).
In additional, it also used another technique such as project milestone is based on the task of
zero duration, which mainly representing the important achievement within project. It is the most
useful term which clearly sequence of event that incrementally build up until the entire project is
complete.
TASK 3
Evaluation of potential project management solution by using PERT
Within project evaluation, it can be used PERT as project management solution which
help for managing and controlling the entire budget, schedule, resource of project. in order to
resolve the various complexities of project in regards of low quality or strength (Kerzner, 2019).
It should be considered the different suitable task in sequential order and follow in step by step
manner (Prošek and et.al., 2020). On the basis of tracking, monitoring the performance of
project. in this way, it prefer to select PERT as best technique which provide the better solution
through complete project with specific time intervals. The overall price/ cost can be used for
concrete recycled technique and implementing solution. Therefore, it can easily manage or
control the overall project efficiency as well as performance.
Justified the selection of project solution with reference to initial stated project.
It has been justified that can implement the most suitable method such as PERT, in order
to resolve all problem or issue which automatically improve the stability, quality of concrete
10

recycled materials within construction project. PERT is consider as useful in identifying all
initial task, which to be completed.
Furthermore, it was determined that initial expected time require for completing project
within 74 days but afterwards, it also used the appropriate solution to complete within 20 days.
In this way, it has analysed that most appropriate solution always justified, which help for
handling entire project activities and completed on specific intervals.
Comparison between the result, outcome of initial planned resources, cost and timescale
Initially, it has planned the construction project resources, price/cost and timescale with
actual result. Therefore, it has been determined the difference on the current situation of project.
Initial Actual
It should be required the concrete raw
materials, equipment and at least 12-16
workforces.
The overall cost require to complete project
£15,000
It should be required the concrete raw
materials, equipment and at least 20
workforces. In order to complete project within
70 days. The overall price of project will be
minimised £11,000
Table: 2
TASK 4
Produce the report of project that consist of different stages or processes
For completing the project, it should be required the different stages for completing task
in proper manner. Each one has performed the effective role to achieve desirable goal or
objective.
 Project introduction: it is important stage of project when identifying appropriate aim,
objective of project. Afterwards, it also considering the suitable solution through specific
problem which associated with the concrete recycling within construction project. This
stage will give brief idea about the entire project (Prošek and et.al., 2020). Afterwards,
project manager will perform the different activities.
11

 Project scope: in this stage, it can be considered the scope of project which mainly setup
the essential resources, cost estimation and time scale.
 Data collection process: in this process, it is basically focused on the collecting large
amount of data or information related the concrete construction project. Afterwards, it has
to be started the different activities.
 Data analysis: in this stage, it may use all essential information which are becoming
useful for project. In order to find out the problem and then apply suitable solution.
 Undertaken suitable action: According to suitable result or outcome, it can easily analysis
essential action which are taken.
Final Project result and recommendations
There are different set of recommendation for London construction contractor firm to
resolve the identified problem within project.
 It has been analysed that concrete construction project fail because of lack of
identification. In order to give more priority of project task. It is an essential for bring
improvement in the resource planning so that it become easier to consider all necessary
requirement of project (Prošek and et.al., 2020). Moreover, it also manage or control the
entire budget as per requirement and complete project with specific timescale.
 Project manager will require to use construction management related hardware, software.
In order to easily identify the task, billing, contractor, bid management, time sheets and
other incident reporting. These are consider as essential process which require to find out
during the construction project (Prošek and et.al., 2020). In this way, it help for
identifying the overall strength of project and also generated the desirable result or
outcome.
 The rare situation occurred when project manager has a lack of knowledge about the
particular technique. In this way, it is very difficult to identify the accurate result or
outcome. In this way, it would require to use the project management plan in which
provide the better idea (Prošek and et.al., 2020). Therefore, it can easily build own
understanding towards the project. Sometimes, it will organise training session whereas
each staff member participate to improve their own knowledge, skill. For construction
12

project, it will require the better coordination between project manager and other staff
members.
CONCLUSION
From above discussion, It concluded that Concrete recycling help in construction project to
reduce waste materials, trying to keep site tidy and safe. Project manager has identified the
contamination problem and other one during construction project. it has summarised about the
project that always keep protect, safe and tidy the construction sites. In this report, it also focused
on the Recycling concrete concept which mainly used for reducing the waste but also identified
the problem. In order to implement suitable solution to resolve issue within project. Furthermore,
it has discussed about the project management plan which including Gantt chart, PERT to handle
the different activities or tasks in proper manner.
