Man 03 - Responsible construction practices

BREEAM Accredited Professionals & Site Sustainability Managers - KBCN1159

All current BREEAM Accredited Professionals will automatically be qualified as BREEAM Advisory Professionals and will be able to carry out their work under the title of ‘BREEAM Advisory Professional Design and Site’ under the new scheme. Existing SSMs, likewise, will automatically be qualified as BREEAM Advisory Professionals and will be able to continue to carry out their work under the title of ‘BREEAM AP Site’. All BREEAM Advisory Professional (design and/or site) will additionally be required to maintain CPD to continue to work in these respective areas. Newly qualified BREEAM Advisory Professionals, who qualify following the implementation of this new qualification, will have their area of expertise recognised by being ‘BREEAM Advisory Professional – Design’ / ‘BREEAM AP – Site’.

BREEAM Advisory Professional (AP) – Retrospectively applying AP status - KBCN1080

The AP status cannot be applied retrospectively. The purpose of using an AP on a project is that they can advise and steer the development from the outset to maximise its BREEAM and sustainability performance for the least cost/risk. If early AP appointment and involvement does not occur then the aims and criteria of this BREEAM issue are not being met.

BREEAM AP – Change of BREEAM APs/Sustainability champions during project - KBCN0295

Whilst it would generally be preferable to retain the same individual in the role of BREEAM AP/Sustainability champion throughout the design and construction of a particular project for the purposes of continuity, we appreciate that this may not always be feasible. It is therefore entirely appropriate that the three credits available for using BREEAM APs/Sustainability champions can still be awarded where the individual performing the role changes (provided the ongoing involvement of an AP/SC is maintained in accordance with the criteria).

Certificate validity – EMS - KBCN1401

The requirement for the principal contractor to operate an EMS relates to the duration of operations on site. Certification against ISO 14001/EMAS must be valid at the Design Stage and Post Construction Stage submissions and cannot be expired, pending or applied retrospectively.

07/05/2021: Clarification on Design and Post Construction Stage added

Changes to CCS – January 2022 - KBCN1500

UKNC2011, UKNC2014, RFO2014 and Domestic Refurbishment 2014 schemes: In response to the 2022 changes to the structure and scoring in the CCS, the adjusted points for credits are as follows for each of the three new sections (Community, Environment, and Workforce): One credit requires a minimum of 9 points per section and 27 overall. Two credits require a minimum of 11 points per section and 35 overall. Exemplary credit requires a minimum of 13 points per section and 39 overall. UKNC2018, UKNCV6 and HQM ONE schemes: No changes have been made to the criteria or the requirement to demonstrate compliance with items g, p and q for the exemplary credit. GN33 has been updated to demonstrate the mapping of the updated CCS to these schemes, see KBCN1215. For assessments not following CSS, the criteria remain unchanged. More information on the changes to the CCS scheme are outlined on the CCS website.

12-Apr-2023 - Updated to clarify the applicability of the new guidance.
28-Feb-2023 - Note updated to refer to the updated version of GN33.
29-Apr-2022 - Note added to clarify that this information supersedes the requirements in the technical manuals.
25-Mar-2022 - Updated to provide the new scoring requirements for BREEAM standards.

Changes to CCS scoring system – January 2019 - KBCN1271

In January 2019, the Considerate Constructors' Scheme (CCS) modified its scoring system, so that innovations are more easily recognised and rewarded. This change does not impact on the established score thresholds, for awarding credits in relevant BREEAM Schemes. For further information on CCS, please follow this link

08/10/21 CCS guidance on changes no longer available. Substituted for a link to main CCS website.

Considerate Constructors Scheme – Phased developments - KBCN0328

The Considerate Constructors Scheme does make provision for phased developments within the registration process, allowing each phase to be registered separately. They make this provision to allow for very large developments that may go on over several years. It should therefore be possible for the developer to register the site in phases, so that CCS certificates can be submitted for BREEAM assessed buildings, without having to wait for the completion of the final phase.

Dedicated off-site manufacturing and fabrication - KBCN0795

Energy use, water consumption and materials' transport data from 'dedicated off-site manufacturing or fabrication' should only be accounted for if the manufacturing process has been specifically developed for the project under assessment, excluding data from manufacturing 'off the shelf' products. The construction impact monitoring should only consider the data that has been specifically generated by the activities of the project under assessment.

Definition – NHS Buildings - KBCN1085

'NHS buildings' refers to projects which are primarily funded in the long term by the National Health Service. 'Prerequisite - For Healthcare NHS building only" applies to any facilities which are owned and managed privately but which source the majority of their income from the NHS.

Definition – Project value - KBCN0552

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

Design team meetings via conference call - KBCN0201

Design team meetings can be conducted via conference calls.

It can be difficult for design team members to be in the same place at the same time. Conference calls are a more sustainable way to conduct meetings.

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.

Evidence requirements – responsible sourcing of materials at post-construction - KBCN1599

Whilst the UK BREEAM manuals are less prescriptive in the evidential requirements to allow flexibility, to ensure consistency across the schemes, it is expected that robust evidence should be provided to verify the source of any certified materials and how the assessor has confirmed the products and manufacturers used. Evidence supplied at post construction stage must reflect the completed building and confirm the responsibly sourced materials that have been procured and installed on the project. Supporting documentation is required to validate letters of confirmation or schedules of materials. Evidence provided could include proof of purchase, for example, invoices, delivery tickets, purchase orders or correspondence from suppliers. This may be an example for each material sourced, rather than every delivery ticket for instance. Alternatively, evidence of the use of the responsibly sourced materials may include as-built drawings, O&M documentation or site photographs.

Fleet operator definition – Responsible construction management items p and q - KBCN1473

The definition of the fleet operator states that “transportation to the project is likely to be by several fleet operators many of which will not be under the control of the constructor. The criteria relate to all fleet operators, nonetheless.” Following feedback on the difficulties of applying the requirements to fleet operators who do not directly work with the contractor, these requirements will only apply to those who are under the control of the principal contractor. ‘Fleet operators’ should now, therefore, be read as ‘all vehicles used or present on site which are owned, leased or hired by the principal contractor’. For clarity this may include, but is not limited to:

company vehicles (cars and vans)
movable plant or powered equipment (such as dumpers, diggers, cranes)
trucks, lorries or waste removal wagons

Item P should, therefore, read: For any company vehicles or plant owned, leased or hired by the principal contractor; driver or operator training and awareness is undertaken to promote safety within the development footprint and off-site. Item Q should read: The principal contractor records, investigates and analyses any vehicular accidents, incidents and near misses; and learnings are incorporated in updated policies and training. This will be amended in the next reissue of the technical manual and GN33.

26 September 2024: This has been updated to provide additional clarification on what is meant by fleet operators under the control of the principal contractor.

FSC and PEFC Mixed Sources certified timber - KBCN00091

Products labelled:

FSC Mix or
PEFC Mixed Sources

Meet the BREEAM responsible sourcing requirements. This means any such products:

In HQM, and in BREEAM NC 2016 or older schemes: meet the prerequisite for legally harvested and traded timber.
In BREEAM NC 2018 or newer schemes: meet the prerequisite for legal and sustainable timber.
In all schemes: can be used to demonstrate responsible sourcing.

Products carrying the FSC Mix label contain at least 70% FSC certified and recycled material. These products may contain a small proportion of FSC Controlled Wood (KBCN00054). However for BREEAM compliance, the FSC Mix label is sufficient to meet our requirements.

14-Mar-2024 - Wording clarified and expanded. Relevant prerequisites and requirements clarified. Scheme applicability updated.

GN33 – Evidence requirement clarification - KBCN1157

In Guidance Note 33 (GN33), BREEAM recognised responsible construction schemes are mapped against the 'Responsible construction management' criteria within the manual, in order to determine the degree of comparability. Table 2 in GN33 provides a mapping of the recognised schemes, the relevant scores and the BREEAM items ‘a-s’ which are achieved. Where items in the table have been 'ticked', the only evidence that is required is confirmation of the formal certification under the relevant scheme, in addition to the evaluation report. No further information is required to achieve these items. Where an item in the table has been 'crossed', this means that either, the responsible construction scheme does not demonstrate compliance with that BREEAM item, or that the score achieved is not high enough to confirm compliance with the item. Where a cross exists against an item, additional evidence will be required to demonstrate compliance with those items, (where credits are sought).

28-Feb-2023 - Updated link for Guidance Note 33

GN33 has been updated - KBCN1282

Guidance Note 33 (GN33) has been updated with new mapping results following the 2022 update to the Considerate Constructors Scheme (CCS). A full description of the change can be found in the 'Schedule of changes' in GN33.

28-Feb-2023 - Updated to refer to latest version of GN33 (v2.0, February 2023). This KBCN previously referred to the changes in GN33 v1.1. The full change history can still be found in the 'Schedule of changes' in GN33.

Legally harvested and traded timber – Examples - KBCN0956

The following examples are considered compliant for BREEAM purposes. Legally harvested:

Evidence of compliance with the CPET (see here, timber bought inside the UK only)
FSC, PEFC or SFI certification
Evidence of compliance with the EUTR (timber bought inside the EU only)
Risk assessment/due diligence documentation demonstrating a low risk of non-compliance with the ‘legally harvested’ requirements given in the manual.

Legally traded:

Evidence of compliance with the CPET (see here, timber bought inside the UK only)
FSC, PEFC or SFI certification
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 - KBCN0654

Timber should, wherever possible, be sourced in accordance with the UK Government’s Timber Procurement Policy. However, if for reclaimed timber the original procurement details are unobtainable, robust evidence to demonstrate it has been reclaimed can be acceptable. The government UK Government Timber Procurement Policy Timber Procurement Advice Note (6th edition) states: As an alternative to demanding timber and wood-derived products from a Legal and Sustainable source, Contracting Authorities can demand ‘recycled timber’. Documentary evidence and independent verification will also apply to recycled timber and recycled wood-derived products but will focus on the use to which the timber was previously put rather than the forest source. And defines ‘recycled timber’ as: “…recovered wood that prior to being supplied to the Contracting Authority 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.” As per the above policy, BREEAM requires “Documentary evidence and independent verification” that all reclaimed/recycled timber products meet the definition of ‘recycled timber’ given above.

01/06/2020: Amended to clarify and extended applicability to Mat 03

Pollution Prevention Guidance documents - KBCN1051

On 17 December 2015, the Pollution Prevention Guidance documents (PPGs) published by the Environment Agency were withdrawn. These can be found in the National Archives or on the Scottish Environment Protection Agency website where they are still current documents. Many BREEAM schemes and the Home Quality Mark refer to these PPG documents as they are still considered to be best practice even though they have been withdrawn. Projects should continue to use the PPGs referenced in the relevant manuals. BREEAM will continue to review this situation and provide an update as and when appropriate.

26 09 2018 Made applicable to Man 03 and Pol 03 in UK NC2018 and Man 03 in UK NC 2011, UK NC2014 and UKRFO 2014

Responsible construction management – corporate registration - KBCN1084

Where credits are awarded for the assessment of the site against a compliant scheme, corporate registration, which assesses the contractor's overall operations and performance across multiple sites, is not in itself recognised. To award considerate construction credits, BREEAM requires the assessment of the specific assessed development, in line with the criteria

Responsible construction practices – Demolition or strip-out - KBCN1257

Demolition or strip-out undertaken by a previous site owner or by the current owner, as part of a significantly earlier site clearance

Where it can be demonstrated that demolition was unconnected to the current development, the requirements of Man 03 do not apply to the demolition phase. This would typically be where demolition was undertaken prior to RIBA stage 0.
Exceptions may also be considered where the demolition was expedited for health and safety reasons. In such cases, this should be fully justified and evidenced.

Demolition or strip-out undertaken by the current developer to enable the assessed development

This must be included in the scope of the Man 03 issue. The site should be managed responsibly at all stages. The risks inherent in demolition and strip-out are as significant as during construction.
This is indicated in the following guidance in the technical manual:
- The wording of Criteria 2-4
- Methodology: ‘Scope of the responsible construction management’
- Definitions: ‘Construction process’
Demolition undertaken by a separate demolition contractor, prior to the principal contractor taking possession of the site
All criteria are applicable.¹The demolition contractor is responsible for compliance.
Where a BREEAM AP has not yet been appointed, Criterion 6 does not apply.

Demolition undertaken by the principal contractor or by others when the principal contractor has control of the site
All criteria are applicable.¹Responsibility is criteria-dependent.

¹Project scale For smaller contractors/projects, for ‘Monitoring of construction site impacts’ and ‘Environmental management’, it may be acceptable to demonstrate that the intent of the criteria has been met for this stage of works, as far as possible. This should be proportionate to the scale and risks associated with the demolition or strip-out. In such cases, the approach should be fully justified and evidenced.

12 Jan 2022 Wording and title updated to clarify the intent.

Responsible construction practices – Multiple contractors on the same project - KBCN0352

It is the site that must comply with BREEAM issues rather than any individual contractor. Several different contractors may have obligations to meet compliance criteria. One of the contractors and/or site managers may have responsibility for ensuring compliance during site operations. It is ultimately the client/project team's responsibility to determine and demonstrate compliance.

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:

For products or materials purchased directly from a manufacturer or quarry, for example, the distance should be calculated from the ‘factory gate’, including any intermediate transport.
For products or materials, which are purchased from a merchant or distributor, only the distance from their depot should be reported.

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.

27.07.2018 Wording amended to add clarity.

Utility consumption – units for project value - KBCN1469

When calculating the total kgCO₂/project value and entering this in the tool, the project value should be reported in pounds sterling i.e. kgCO₂/£1

[KBCN withdrawn] ~ BREEAM AP and BREEAM assessor – conflict of interest - KBCN0196

This KBCN has been withdrawn and replaced with the more detailed KBCN1708.

KBCN Withdrawn on 18th Oct 2024

An individual can be appointed as a BREEAM/HQM Assessor and BREEAM AP/Sustainability Champion for the same project, where the Assessor also holds current and applicable AP/Sustainability Champion credentials.

If this route is chosen, it must be made clear when submitting the assessment that both roles are being carried out by the same person and confirmed how potential conflicts of interest are identified and managed. This will mean, when appropriate, that the assessment can be escalated to a more detailed level of quality assurance checking.
