WAS 02 - Refurbishment Site Waste Management

Contractor not yet appointed at the design stage - KBCN000002

Where the contractor has not been engaged at the design stage certification, it is acceptable to award the credits based on a commitment. This commitment must be from a suitable member of the design team, and must detail the targets and criteria which must be met. Evidence must also confirm that the details in the commitment will form part of the contractual requirements. Note: This does not apply to the requirement for a pre-demolition/pre-refurbishment audit, which must be undertaken at Concept Design Stage.

12 Jul 2022 - Note added to clarify the scope of this guidance

Excluding excavation waste from ‘Diversion of resources from landfill’ - KBCN0226

Excavation waste should not be included and assessed against the requirements under ‘Diversion of resources from landfill’. This also applies to BREEAM Communities RE05 - 3rd/4th credits.

Pre-demolition audit requirement - KBCN0243

Where the site demolition/clearance does not form part of the principal contractor’s works, but has been undertaken by the developer for the purposes of enabling the assessed development, a pre-demolition audit must be carried out and referenced within the SWMP as per the guidance. Where justification and robust evidence can be provided, the following exceptions may apply:

Where it can be demonstrated that demolition/clearance was carried out prior to the developer acquiring the site and no pre-demolition audit is available.
Where the demolition was expedited for health and safety reasons.
Where the demolition has been carried out by the same developer, but as part of a significantly earlier site clearance, occurring prior to RIBA stage 0 and no less than 12 months ahead of the requirement being set to carry out a BREEAM assessment. In such cases it must be clearly demonstrated that the demolition was unrelated to the current re-development.

This requirement seeks to encourage good practice by developers and design teams in relation to previously developed sites.
