Man 03 - Construction Site Impacts

Information correct as of 11thApril 2021. Please see kb.breeam.com for the latest compliance information.

Change in main contractor - KBCN0645

In situations where the main contractor changes mid-project, for example where the original contractor goes into administration and is replaced by another main contractor, it is acceptable for the post-construction credits to be awarded based on the new contractor providing information on their activities. This is providing the project is yet to start on site. This is in effect assessing the issue using the Post Construction Assessment route instead of a Post Construction Review. However, if the project has already started on site and information about the site activities of the previous contractor is not available it would not be appropriate to award the credit solely based on the new contractor activities.

Definition – Project value - KBCN0552

The term ‘project value’ represents the total project cost, which includes all costs such as construction, design, land acquisition etc.

Environmental management – no principal contractor - KBCN1213

In order to achieve compliance where there is no principal contractor, the criteria must be met by the party which fulfills an equivalent role in managing the construction. The intent of the criteria is to ensure that the site is managed in accordance with demonstrably sustainable principles by the party having overall control of site management and operations. 

Environmental management – Timing of obtaining ISO 14001/EMAS certification - KBCN0229

The contractor must be in possession of the ISO 14001/EMAS certification prior to starting works on the development under assessment. This is to ensure that the aim of the issue, to ‘encourage construction sites managed in an environmentally sound manner’, can be achieved. To uphold the robustness of BREEAM, the date of certification to ISO 14001/EMAS must be prior to initial works starting on the site.  

Legally harvested and traded timber – Examples - KBCN0956

The following examples are considered compliant for BREEAM purposes. Legally harvested:
  1. Evidence of compliance with the CPET (see here, timber bought inside the UK only)
  2. FSC, PEFC or SFI certification
  3. Evidence of compliance with the EUTR (timber bought inside the EU only)
  4. Risk assessment/due diligence documentation demonstrating a low risk of non-compliance with the ‘legally harvested’ requirements given in the manual.
Legally traded:
  1. Evidence of compliance with the CPET (see here, timber bought inside the UK only)
  2. FSC, PEFC or SFI certification
  3. Risk assessment/due diligence documentation demonstrating a low risk of non-compliance with the ‘legally traded’ requirements given in the manual.

Legally harvested and traded/Legal and sustainable timber – Reclaimed/recycled timber - KBCN1402

As an alternative to virgin timber and wood-derived products from a Legally harvested and traded timber/Legal and Sustainable source, ‘recycled timber’ is acceptable. For the purposes of these prerequisites, ‘recycled timber’ is defined by BREEAM as: Recovered wood that prior to being supplied to the assessed project had an end use as a standalone object or as part of a structure and which has completed its lifecycle and would otherwise be disposed of as waste. The term ‘recycled’ is used to cover the following categories: pre-consumer recycled wood and wood fibre or industrial by products but excluding sawmill co-products (sawmill co-products are deemed to fall within the category of virgin timber), post-consumer recycled wood and wood fibre, and drift wood. It also covers reclaimed timber which was abandoned or confiscated at least ten years previously. BREEAM requires documentary evidence that all reclaimed/recycled timber products meet the definition of ‘recycled timber’ given above.

Scope of construction works included - KBCN0642

Only the scope of works the principal contractor is responsible for needs to be considered in the assessment of this Issue. This also includes works carried out by sub-contractors that are engaged by the principal contractor.

Transport of construction materials – Data and methodology - KBCN0413

To ensure comparability across assessments, the information completed in the scoring and reporting tool should be restricted to the minimum data specified in the technical manual. For the purposes of this BREEAM Issue, the distances reported should be calculated from the point from which the products or materials were sourced, whether this be directly from a manufacturer or from a builders' merchant/distributor: Where products cannot be sourced locally, for example on small islands, the transport required to import the materials or products can be discounted, and only the local onward transport to the site recorded. The aim of this requirement is to encourage developers to consider the impacts of transporting products and materials to site. As such, the criteria seek to address only those impacts, which can be influenced by the developer.
