Environmental Issues in Construction Projects

Question 1
Environmental issues affecting the construction and operations of the project
The idea of construction project development may be greatly compromised if there is no
sufficient knowledge and proper management of the impacts of the environmental factors
influencing the construction and the performance of such projects. The construction industry is
complex in nature since it contains large numbers of parties such as contractors, client,
consultants’ regulators and shareholders among other. Many construction projects suffer
Role of BIM in project delivery
With the continued growth in the information technology in the construction industry ,
numerical building information modelling and process simulation has developed to a fully
accepted and widely applied tools for the project life cycle management. The growing diversity
between the various construction arties, teams, tools, task and events. A growing diversity
between disciplines, participants, tasks, tools and events while project management in design and
construction stages [3], the rising pressure of costing competition and tighter production
deadlines, together with consistently increasing quality requirements and necessity of
technological enhancements, have been the driving force of information modeling and numerical
simulation in building industry.
The linking of the biding information with a computer software to generate 3D building model
referred to as BIM. The BIM will have a wide application in the execution this given project
since it can be applied in the designing process, construction process, maintenance and operation
of the project. BIM facilitates control of knowledge creation, sharing, storage, acquisition,

dissemination and the application to the current project. The figure below shows BIM knowledge
management cycle.
Application of BIM during planning stage
The activities which are involved in project planning will include master planning and urban
design, master planning refers to the regulatory framework which will control the
development of the collection of project components with the overall consideration for their
massing, connectivity, relationships and heights. He regulatory framework will give sufficient
details in the context of the social , environmental , economic, security, services and
infrastructure. All the information regarding to the above project components will be gathered
and be stored in the BIM repository. The stored data will be of great importance in the

subsequent project phases.
Application of BIM in Designing stage
The information which was gather and stored in the BIM repository during the planning stage
will govern the design stage of the project. The main aim during the primary design is to ensure
that the development of design and construction documents which are required to ensure the
project delivered will be functional , liveable, secure, safe and sustainable. All the decisions
which will be made during the design stage should make consideration of the constructability,
operational and maintainability of the proposed project sharing at the design stage.
Application of BIM in construction stage
. BIM will provide a collaborative environment for the information and the knowledge
Question 2
Role of the Built Environment Practitioners in this development project
All the practitioners who will take part in the development of the project will be tasked to carry
out specific roles and responsibilities. For the project to be implemented there must be a team
of practitioners such architects, engineers, quantity surveyors, contractors, construction
managers, town planners among. The chart below show different Practitioners who will be
involved in the project, their roles and responsibilities of each of the practitioners are discussed
below.
