Waste management at construction sites

Groups: 
  • Design-Build Contracts
Category: 
  • Waste management

Basic

Requirements and Criteria Type: 
  • Contract Terms

Main Objective: 

The production of construction materials accounts for a large share of the energy and climate footprint in construction projects and the materials, in addition to the materials being resources. 

Through the planning of material use and by selecting prefabrication, it is possible to reduce unnecessary waste from excess materials and wastage through breakages, broken/damaged materials, etc.

Proper sorting and management of waste at the construction site contributes to ensuring that more of the waste is sent for material recycling

Requirement Specification: 

The contractor must estimate the waste volumes for the product, describe measures to reduce the waste volumes in the project by 5% and submit an overview of what will be sent for material recycling. Materials that contain environmental toxins must not be recycled.

Construction sites must appear orderly at all times. Waste must be properly managed and delivered to an approved recycling centre.

At the construction site, the contractor must ensure:

  • That waste containers are labelled (in multiple languages)
  • That information posters concerning sorting of waste are visible
  • That hazardous waste is recorded.
  • That waste that is harmful to health or the environment is locked away and properly stored
  • Sorting ratio: per cent per weight 60

Documentation of the Requirement Specification: 

The final report and waste plan must document the management of all waste that has occurred in the project, the sorting ratio, reduced waste volume and an overview of what has been sent for material recycling.

Information about the Requirement Specification: 

The best thing we can do for the environment is to not use unnecessary resources. Proper planning is therefore crucial so that we throw away less.

In order to reduce waste from construction sites, the waste pyramid (figure 1) shows the order in which the measures should be taken. The most effective measures are at the top, in line with the priorities in the EU framework directive on waste.

Figure1: The waste pyramid shows the priorities for reducing waste. It should be read from top to bottom.

It is important to ensure that a waste contractor has been appointed prior to the project starting, so that solutions are in place from day one. It is crucial that the contractor has a plan in place concerning the logistics associated with sorting of waste on site and the transport of waste in the various phases of the project, in order to succeed in the goal of having a high degree of waste sorting on site. The client should also request this plan as part of the monthly reports and should provide feedback in the event of any non-conformities in order to ensure that there is a continuous focus on waste management.

There are good economics associated with a reduction in the volume of waste and in sorting the waste that occurs to the extent practically possible.

Proper sorting and management of waste at the construction site contributes to ensuring that more of the waste is sent for material recycling

Requirement Specification: 

The contractor must estimate the waste volumes for the project, describe measures to reduce the waste volumes in the project by 10% and submit an overview of what is sent for material recycling. Materials that contain environmental toxins must not be recycled.

Construction sites must appear orderly at all times. Waste must be properly managed and delivered to an approved recycling centre.

At the construction site, the contractor must ensure:

  • That waste containers are labelled (in multiple languages)
  • That information posters concerning sorting of waste are visible
  • That hazardous waste is recorded.
  • That waste that is harmful to health or the environment is locked away and properly stored
  • Sorting ratio: per cent per weight 80

Documentation of the Requirement Specification: 

An overview of the delivered waste volumes and types, including receipts from recycling centres, must be documented as part of the monthly report submitted to the client. 

The final report and waste plan must document the management of all waste that has occurred in the project, the sorting ratio, reduced waste volume and an overview of what has been sent for material recycling.
