Figure 6: Systematic process for construction waste management through life cycle of a building
Phase 1: Objective
Developing the waste management plan and setting the waste management policy at an early phase is important. In relation to this, the requirement for good practice in construction waste management should be introduced at the outset of a project. Proactive waste management plans begin with setting specific objectives by the project owner / client, which should be understood by the project team. The main objectives in achieving the effective waste management plan must be clear and should be included in the project brief by the owner / client.
Phase 2: Planning, design and procurement
The requirement set by the client / owner will create a key opportunity for the project team to consider and implement the waste minimisation plan. The project team must be able to deliver what is stated in the project brief. An overarching strategy to achieve waste minimisation begins during programming and planning. Involvement of the project team at the early phase is crucial in ensuring that the waste management plan can be sustained throughout the building life cycle. The selected consultants are the persons who must have sound environmental policies or in-house best practice documents.
Phase 3: Construction
The construction phase of a project will produce the greatest impact to minimising waste produced. The waste management plan developed during the early phase must be adopted on site. Policies related to waste management on site include monitoring and record keeping of wastes leaving the site, which must be formulated and reviewed periodically in light of the developments during construction. Designated locations where wastes are dumped in separate compartments enable recycling because fewer efforts are needed to separate wastes than when these are indiscriminately dumped. Policies on packaging material can drastically reduce the amount of waste generated on site, if the packing material is collected by the material supplier, either for final disposal or reuse and recycling.
Contractors should be encouraged to develop and propose new methods of construction to reduce the production of waste. Meetings and reports regarding waste management and minimisation on site should be held every week or every month, depending on the levels of involvement;
●● the contractor alone is involved;
●● the contractor and the consultant are involved; or
●● all parties involved in the project.
