Alignment of RFO fit-out with New Construction shell only and shell and core assessments - KBCN0731

Where seeking a fully-fitted certificate for a shell only or shell & core project assessed against the BREEAM NC 2014 scheme, the advice provided within the scope section of the RFO manuals has been superseded. The original concept to provide ‘fully-fitted’ ratings and certificates following BREEAM New Construction shell or shell and core certificate has been dropped in favour of separate independent assessments, certificates and scores in the normal way. This is partly due to lack of demand and partly due to the complexities of mapping, managing and scoring one set of criteria against another at completely different stages. For a comprehensive BREEAM assessment of a project that has two separate construction stages, two separate BREEAM assessments should be undertaken. For example, a shell only BREEAM New Construction assessment, the same as Part 1 in BREEAM Refurbishment and Fit-out (RFO), will have a certificate for the original design. Later on, the fit-out (RFO Parts 2, 3 and 4) can be undertaken and will have a separate certificate. The two separate certificates will then represent a comprehensive BREEAM assessment and best reflect the different scopes of the different project stages.     
This will be be updated in the next reissue of the technical manual.

Asset classification – co-living developments - KBCN1568

The following is a guide only. Every co-living project will combine a varying mix of residential with managed spaces, and assessors must in all cases review the suitability of the criteria to determine the most appropriate asset classification. Co-living features Co-living developments generally combine: Classification Using building regulation classifications as a guide As a guide, assessors can also consider how their asset is classified according to local regulations. For UK NC assets, KBCN1225 provides additional clarification:

BREEAM New Construction UK 2018 – Post-Occupancy Stage assessment - KBCN1532

Following the publication of UK NC V6 it was announced that the Post-Occupancy Stage (POS) assessment within BREEAM will close with immediate effect. While we will no longer be offering this as an assessment option, the essence and intent behind the criteria will remain. At this stage, we will not be re-issuing the UKNC 2018 manual. Therefore, reference to POS will remain within the following issues:
  1. Ene 01 Reduction of energy use and carbon emissions (two credits for Post-Occupancy Stage)
  2. Ene 02 Energy monitoring
  3. Wat 01 Water consumption
  4. Wat 02 Water monitoring
To award the relevant credits, the references to ‘Post-Occupancy Stage assessment’ should be read as ‘Post-Occupancy Evaluation’ and carried out with the same intent; to understand and close the performance gap. For assessments that have been certified at Post-Construction, are in progress or are new assessments, the Post Occupancy Evaluation process should continue to be followed, however there is no formal post-occupancy BREEAM certification stage. Rating systems such as BREEAM in-Use and NABERS UK Energy for Offices are examples of tools that can be used to measure performance in the operational phase. 
18-05-23: KBCN edited to illustrate that credits can be awarded.

Cat A fit-out - KBCN0791

For Category A projects the assessor can decide, based on the developer’s scope of works, whether to assess as shell and core or fully-fitted. In determining the most appropriate classification, it should be borne in mind that if a fully fitted certification is sought, a higher level of certification would be achieved and more credits would be deemed under the scope of the assessment. However, where the actual scope of works does not comprise of some fit-out elements, the BREEAM rating might be penalised. More information on Cat A projects is given in Appendix D of the technical manual, as per the extract below:

Appendix D – BREEAM UK New Construction and Shell and Core Project Assessments

… Often, shell and core projects will also be fitted out to a 'Category A' standard, the scope of which varies between different developers, but often includes in addition the shell and core of the building the provision of raised floors, suspended ceilings, extension of core services above ceilings across the lettable space, finishes to the internal face of external and core walls and blinds. Upon completion, the whole building or space within the building is sold or let to be fitted out as appropriate for occupation. The new owner(s) or tenant(s) will fit-out the building’s accommodation in accordance with their corporate and operational needs, often referred to as a 'Category B' fit-out. These terms, while they are widely used in the property sector, are not used within BREEAM as the scope of works that they refer to varies significantly between developers making them not comparable. In these projects, where areas of the development are not fully fitted, performance of the building and compliance with BREEAM is verified based on the developer’s scope of works. This is measured using two standard project type options that in turn define appropriate assessment criteria applicable to that project type. While some projects will differ to some extent from the scope of these standard options, for the purpose of BREEAM, issues not included within the chosen option will be excluded from the assessment, even where they are within the developer’s scope of works. This approach is necessary to ensure clarity, consistency and comparability within the property market. A fully filterable list of criteria/issues based on each individual projects scope would not enable comparability between BREEAM ratings, either in terms of performance benchmarking or promotional/publicity purposes.  

Compliance: Applicability of criteria to subsequent schemes’ versions - KBCN0554

When assessing a project under a certain scheme, criteria or compliance notes from a previous scheme cannot be used to demonstrate compliance.

Compliance: Applicability of criteria to scheme’s previous versions - KBCN0430

Criteria set for a scheme version are not applicable retrospectively to previous versions.

Compliance: Statutory requirements - KBCN0395

BREEAM is an assessment method which promotes best practice in sustainable buildings. Matters critical to health and safety, as well as any mandatory requirements from statutory authorities which conflict with BREEAM criteria may take precedence over BREEAM requirements. In this instance, evidence would be required to demonstrate that this is the case. Note, this does not change the criteria requirements, and where BREEAM requirements are not met the design team must explore alternative options or specifications if the relevant credits are to be awarded. 
17/04/18 Wording amended to clarify

Definition of NIA (net floor area) for assessment registration purposes - KBCN0569

Net Internal Area (NIA) is broadly the usable area within a building measured to the face of the internal finish of perimeter or party walls ignoring skirting boards and taking each floor into account. NIA will include: NIA will exclude: Source: Valuation Office Agency Therefore, the usable area within a building measured to the face of the internal walls should be provided. Whilst this is not expected to be accurate to the nearest 1m2, the closest estimate possible for the NFA should be entered. This is to allow for any possible subsequent adjustment to the size of the development.

Dementia care homes - KBCN0820

For dementia care homes, there may be instances where the resident profile, and hence design and use, result in some BREEAM criteria being considered inappropriate or not applicable. Where this is the case assessors should seek confirmation from BREEAM through the technical query service, providing a clear justification for why specific criteria cannot be met. Before submitting a query, however, please review the BREEAM Knowledge Base under the relevant Scheme and Issue, to check for a specific, published compliance note. Assessors will be required to provide evidence. This could be from suitable individuals/organisations regarding the specific project, detailing how the criteria is not relevant for the individual project.

Evidence – Photographs not permitted for security reasons - KBCN0389

Where photographs are not permitted during a site visit for security reasons, in addition to any alternative evidence requirements listed in the Schedule of Evidence for each issue, the assessor will also need to provide a detailed site inspection report and/or as-built drawings (where permitted by the client). If following this approach, full justification and documentary evidence from the client will be required for QA purposes.

Evidence: Final design/’as-built’ drawings as evidence - KBCN0393

Where drawings are not clearly marked to indicate their 'as-built' status, additional evidence would need to be provided by the design team to confirm the drawings represent the completed development and that there have been no changes relevant to the BREEAM/HQM assessment. This could, for example, be a written confirmation from the architect or the contractor, as appropriate.

Evidence: Post construction assessment evidence - KBCN0407

For the purposes of robustness and completeness, both design AND post-construction stage evidence is required for a post construction assessment. However, it is possible to provide only post construction stage (PCS) evidence where it is clear that this completely supersedes the design stage (DS) evidence and renders it unnecessary.

Fit-out level – Selecting the appropriate assessment type - KBCN1627

Projects designed and constructed as fully fitted should not be evaluated as ‘Shell and core’ or ‘Shell-only’ where the intent is to limit the scope of the BREEAM assessment without further justification. Where the fit-out level of a project is not consistent, the BREEAM assessment type should be considered in line with KBCN0702

GN40 Reporting template for ecology assessment issues in BREEAM and HQM - KBCN1190

Latest version: v0.2, July 2022 Guidance Note 40 is an optional template to help Assessors relate information generated during a project to the latest ecology assessment issues in BREEAM and HQM. This document has been produced to support the assessment of these issues and should not be interpreted as criteria. If the Assessor chooses to use the template as evidence, then the Assessor, project team member, or appointed Suitably Qualified Ecologist must complete all relevant sections. The completed document can be used by the Assessor along with relevant project documentation to demonstrate compliance with BREEAM or HQM criteria.

Green lease agreement – applicability - KBCN0897

Green Lease Agreements or other shell & core options (green building guide and developer-tenant collaboration), which were included in UK NC 2011, International NC 2013 and earlier scheme versions are no longer available to demonstrate compliance. The only exception to this is for Issue Ene 01 for Shell and Core assessments (as detailed in CN/Specific note 1.2). For all other Issues projects are assessed based on the level of works/assessment type being undertaken. 
17/04/18 Reference to 'specific note' added to align with UK NC2018

Healthcare: BREEAM Assessor Training for Healthcare Buildings - KBCN0470

There are no requirements for training or becoming a licensed BREEAM assessor specific to healthcare buildings. Please review the relevant courses available from the BRE Academy relating to BREEAM New Construction and BREEAM Refurbishment and fit-out. 
17/04/18 Guidance clarified

Laboratory containment level category definitions - KBCN0943

BRE does not designate or define containment levels for laboratories. The categories listed in the manuals are based on industry standard definitions. For further information, please refer to HSE/COSHH or DEFRA definitions, depending upon the hazard type.

Master plans with multiple stakeholders - KBCN0953

Assessment of a building forming part of a master plan co-ordinated by a third party (developer or local authority) In such cases, it may not be possible for the design team to control elements affecting issues such as land use and ecology, access, external lighting and surface water pollution. It is therefore acceptable for the assessor to define the assessment boundary according to one of two following options:
  1. Restrict the boundary only to what the design team can control.
  2. Extend the boundary to include elements of the master plan, assessing any associated benefits or disadvantages that arise. Relevant Knowledge Base Compliance Notes should be reviewed, and BREEAM Technical contacted for additional guidance if required.
The assessment boundary must remain consistent throughout all issues. Facilities outside of the boundary but serving the assessment (i.e. cycle facilities, parking etc) can be assessed as standard. Assessment of a building forming part of a master plan co-ordinated by the design team with third party elements Where there are third party elements in the master plan which are not BREEAM compliant (e.g. external lighting by local authority), evidence should be submitted to QA that efforts have been made with the third party to align these elements with BREEAM criteria. Where this is not possible, these elements can be excluded. Full justification should be provided when submitting the assessment for certification.

Principal contractor or subcontractor no longer operational - KBCN0590

In situations where the principal contractor or other company involved in the project is no longer operational where, for example, the company has gone into administration, the assessor may be unable to obtain all the evidence to meet the requirements of BREEAM or HQM. For some BREEAM Issues, it may not be possible to demonstrate compliance retrospectively, and in such cases, the relevant credits must be withheld. However, in this situation, a lack of complete evidence will not, in itself, prevent the project from achieving a BREEAM rating and, where relevant, a prerequisite or minimum standard can be waived. For example:

UK NC V6 Man 03 Prerequisite - Legally harvested and traded timber or INC V6 Wst 03a – 1 credit to achieve an Excellent Rating

This is based on the project team demonstrating appropriate efforts to obtain the evidence from the company in administration and providing the following:

Process Notes - KBCN0611

Process notes can be accessed by licensed assessors here. When a new process note has been released, you may be required to tick the box to confirm you have read the note to be able to access other documents in BREEAM Projects. To do this scroll to the bottom of the Process Note index page and tick the box and click next.  

Process: Registration date and applicable scheme manual issue - KBCN0708

Typically the scheme technical manual issue which is current when a project is registered should be used for the assessment. For example, if a BREEAM UK New Construction 2014 development was registered on 01/07/2016, the current issue of the scheme technical manual at that point would be issue 4.1, which was published on 11/03/2016 (the next issue 5.0 of the technical manual was published on 05/09/2016). However, it is permissible for the assessor to decide to use a later issue of the technical manual. The scheme technical manual version and issue used for the assessment should be clearly referenced within the assessment report. Note that in any case, the same technical manual version and issue should be used for the entire assessment. It is not acceptable to assess different credits based on different issues of the technical manual and it is not acceptable to change issues between submissions of the assessment. 
26 09 17 Clarification added that the 'Issue' of the technical manual may not be changed between assessment submissions

Registering assessments to UK NC2018 or UK NC V6 – Version of Part L - KBCN1535

BREEAM UK New Construction 2018 was developed for buildings in England which are demonstrating compliance against Part L 2013. The New Construction V6 version is intended for buildings in England which are demonstrating compliance against Part L 2021. Accordingly, UK NC 2018 will only accept 'inp' files created using Part L 2013 building regulations software for England and UK NC V6 will only accept 'inp' files created using Part L 2021 building regulations software for England.   Assessments already registered to BREEAM UK NC 2018 that must comply with the Part L 2021 of the Building Regulations may follow either of the options below:
  1.  Transfer to the UK NC V6 scheme
  2. Assess under UK NC 2018 and do two Part L models:
New assessments subject to Part L 2021 may register to UK NC V6 or follow Option 2, above.

Retail/Industrial Showrooms Appendix - KBCN1115

This Criteria Appendix has been developed for developments such as car showrooms which incorporate both retail and industrial areas. The appendix clarifies, for specific BREEAM issues, which criteria are applicable to each area of the assessment. This should be read in conjunction with the relevant scheme version of the BREEAM UK  technical manual. This is applicable to BREEAM UK New Construction 2014, 2018 and V6 and BREEAM UK RFO 2014. Such assessments should be registered against the 'Retail' building type and the Appendix will soon be available for download in the guidance for 'Retail' assessments for each relevant scheme on BREEAM Projects. In the meantime, the Criteria Appendix can be requested by emailing [email protected] 
22/09/2022 Applicability to UK NC V6 confirmed
22/05/2018 The title of this appendix has been changed and additional information provided. This includes removal of the specific reference to 'Car Showrooms' in order to clarify that this approach can be applied to other similar retail developments, which include industrial servicing areas.

Scheme classification – Education - KBCN0398

The Education scheme classification criteria is tailored to the requirements of buildings that are likely to be used by large numbers of students, whose requirements differ slightly from the general population. Where a building on an education campus, or owned by an educational institution: - is not used for teaching / study - is primarily used by staff or other non-students - and transport requirements differ from a standard Education building The building may be assessed under a different, more appropriate scheme classification. Where it is unclear how this building should be assessed, a scheme classification query should be submitted.  

Scheme classification based on anticipated occupancy & building use - KBCN0421

In the instance where there is potential for the building occupancy and use to change during the building lifetime, scheme classification should be based on the most likely occupancy and use of the building as anticipated at the time of the assessment. Please refer to Guidance Note 10 (GN10) for further details

Scheme classification for residential projects (UK) - KBCN1225

Choosing the right scheme for developments is the starting point to ensure successful outcomes and value, in terms of quality and sustainability to building owners and for occupants of the building. In light of the release of Home Quality Mark (HQM) ONE we have reviewed the existing guidance around scheme classifications of new build residential buildings and have removed ‘GN03 – Scheme Classification – Domestic buildings’ from BREEAM Projects. When GN03 was written, the Code for Sustainable Homes (CSH) did not fully consider communal areas within residential blocks as part of the assessment. CSH was also not applicable in Scotland. GN03 was developed to clarify the differences between BREEAM Multi-Residential, CSH and EcoHomes, and when each scheme should be applied. There is now a clearer distinction between BREEAM Multi-residential and HQM and when these should be used. Ultimately, the determining factor for a scheme classification is now focused on the intent of the building and who is going to be the end user (as opposed to previous guidance which considered aspects such as percentage of communal areas, etc.). Broadly, if the building’s main purpose is for long term homes then Home Quality Mark is the correct scheme to use. Please use the following as guidance to identify the most appropriate scheme: Home Quality Mark (HQM) HQM has been designed with the occupant in mind. It assesses homes individually, but can also account for common areas associated with blocks of self-contained homes. HQM outputs (rating and indicators e.g. ‘my cost’, ‘my wellbeing’ and ‘my footprint’) are specifically aimed at those living in the home and are designed to better inform the occupant about the benefits of the home that they are purchasing or renting. An HQM project will meet one or more of the following criteria: Be designed to meet the function of a long-term self-contained home even though there may be some provision of communal facilities which can be used on a voluntary basis Be classified under Building regulations Part L1a (i.e. required to complete SAP assessments, although there may be some linked SBEM assessed spaces associated with the project) As such, HQM projects could be homes for sale, social housing or homes for rent (PRS and Built to Rent). They may also include some student and retirement/sheltered accommodation where the units are comparable to a normal self-contained flat/home. BREEAM Multi-residential For the purposes of BREEAM Multi-residential assessments, the term ‘multi-residential’ is used in the context of buildings that contain rooms for residential purposes alongside communal facilities for catering, leisure, care etc. These residential rooms would normally not have the full, self-contained functions of a home. This scheme usually covers more specialist residential care homes, student halls of residence, and other more communal accommodation. The scheme can cater for a small number of self-contained dwellings where these form part of a larger multi-residential development (e.g. on-site warden homes etc.). Under this scheme, the project is assessed on a whole building basis and as such does not seek to reflect the performance of individual residential units/rooms. A BREEAM Multi-residential project will meet one or more of the following criteria: Be provided for transient /non-permanent occupants Provide suitable accommodation for occupants requiring support from carers, wardens or similar Include shared living spaces Be classified under Building regulations Part L2a (i.e. required to complete SBEM assessments, but can account for some SAP assessed spaces where associated with the project) As a rule of thumb, if the building contains rooms rather than self-contained flats or homes, a BREEAM Multi-residential assessment would probably be most appropriate. We are aware of some confusion over the meaning of the term ‘multi-residential’ in this context and will be considering the use of term as part of the next review of the BREEAM Multi-Residential scheme. If you are unsure of the appropriate scheme classification for a particular project, please contact the BREEAM office before registering the project.

Scheme classification queries - KBCN0540

As the Operational Guidance clarifies ‘…A scheme classification requires the assessor, client or design team to submit floor plans showing the layout of the building(s) along with its intended functional areas and any other relevant information. BRE Global will then confirm the appropriate means of assessing the development, using either one or more standard schemes or by developing project-specific bespoke criteria…’ BREEAM Technical cannot definitively confirm a scheme classification in the absence of drawings. Relevant information could also include specification of the scope of works, clarification of general building functions, spaces within them, as well as their management and access to the public.  

Scope – Fully-fitted assessments with areas completed to shell & core - KBCN1233

In such situations, the following options can be followed: 1. Include the shell & core area in the fully-fitted assessment, however this may have a negative impact on the assessment, as all aspects of this area would need to be assessed against the fully-fitted criteria. 2. Exclude the shell & core areas from the assessment. Note that this may require the BREEAM certificate to be endorsed to clarify that the whole building has not been certified. It may be possible to assess the shell & core area separately, if required. 3. Wait until the shell & core areas have been fitted-out before certifying. Please also refer to KBCN0702.

Scope: BREEAM UK New Construction 2014 and 2018 in different countries - KBCN0498

Separate versions of the BREEAM UK New Construction 2014 and 2018 technical manuals are available for England, Wales, Northern Ireland and Scotland to reflect the differences in building regulations for each country. These separate versions are derived from the main BREEAM UK NC technical manual and enable country-specific assessments within the single UK scheme. BREEAM UK NC accounts for the differences in building regulations in England, Wales, Northern Ireland and Scotland. 
17/04/18 Amended to include BREEAM UK NC2018

Scope: Discontinued Schemes – Fire Stations & Forestry Commission Visitor Centres - KBCN0493

The standalone BREEAM New Construction schemes for Fire Stations and Forestry Commission Visitor Centres have been discontinued. Assessments of these building types should be registered under BREEAM UK New Construction, which addresses all relevant issues from the superseded schemes.

Scope: Fully fitted, shell and core and shell only – guidance for classification - KBCN0702

In cases where a project is a mix of fully-fitted, shell & core, or shell only, or the scope falls somewhere between assessment types, BREEAM cannot determine the type of assessment on behalf of the assessor/developer. For example, assessing a project which falls between (or is a mixture of) shell only and shell & core as 'shell only' will result in a BREEAM certificate for that part of the work and will not account for any work beyond the scope of that assessment type. For the same development a 'shell and core' assessment would take account of a wider scope of work, however some BREEAM credits might not be achievable because compliance cannot be demonstrated for the shell only areas. The latter approach would achieve a higher level of certification (as shell & core) but may result in a lower score and BREEAM rating being achieved. Similar considerations apply in the case of fully fitted and shell and core projects. The assessor should, therefore, review the scope of the development and advise the developer accordingly.

Scope: Mixed BREEAM CSH/HQM developments - KBCN0383

In general terms, any relevant areas or facilities which serve the building should be included in the BREEAM assessment, regardless of whether they are also assessed under CSH/HQM. Whilst CSH is a Department for Communities and Local Government (DCLG) scheme, it was developed by BRE Global and the requirements are generally aligned with BREEAM. This should not, therefore involve the duplication of work, but means that the same evidence can be applied to each scheme as appropriate.  

Shell & core project: Completing as fully-fitted - KBCN0394

It is possible to complete an assessment as fully fitted following a design stage certification as a shell & core project. Whilst the assessment will reference much of the same evidence gathered for design stage, it must be re-registered and may be submitted as a fully-fitted Post-construction assessment. 
17/04/18 Wording clarified

Simple Buildings – definition - KBCN0448

The building services are predominantly of limited capacity and local in their delivery, largely independent from other systems in the building fabric and avoid complex control systems. The building can be classified as any of the building types within the scope of the scheme, including mixed use developments or building types. For UK NC 2011 assessments please refer to the Simple Buildings Guidance on the Extranet. For UK NC 2014, 2018 and UK RFO 2014 please refer to Appendix E within each technical manual.

Simple Buildings – Additional training - KBCN0464

The Simple Buildings technical guidance does not constitute a separate BREEAM scheme. It is an approach which can be applied to developments which meet the relevant BREEAM definition. This means that a suitably trained, qualified and licensed assessor can conduct a Simple Buildings assessment without further training.

Simple Buildings – Category weightings - KBCN0458

Category weightings are the same for standard and Simple Buildings assessments.

Simple Buildings – connecting to existing services - KBCN00037

Where a building extension will connect to existing building services, a Simple Buildings assessment can be carried out if the total services systems is of limited capacity and complexity conforming to the definition and scope of a Simple Building. Refer to the Applicability of Simple Buildings assessments for more detailed information. For example, the total capacity, when assessing the space and/or hot water heating services, must be less the 100kW. Compliance would be met by any of the following: The assessment (in this case, extension) cannot be assessed against the Simple Buildings methodology if the definition of a Simple Buildings is not meet. 

Simple Buildings – Introduction and robustness of Simple Buildings criteria set - KBCN0454

Simple Buildings criteria have been developed to meet the need expressed by stakeholders for a simplified and cost effective approach for the assessment of less complex buildings. The standards and robustness of a BREEAM rated building have not been compromised by the development of Simple buildings criteria. The criteria have been carefully reviewed to be more in line with and relevant to simpler buildings and servicing strategies.

Simple Buildings – No size or cost limits - KBCN0451

Variations in project specification make setting limits on the size or the cost of simple buildings problematic. Therefore, no limits have been set.

Simple Buildings – Quality Assurance (QA) - KBCN0459

The process and rigor of quality assurance does not change for Simple Building assessments.  As with any assessment, the correct classification of the development will be checked.  Where a project is incorrectly classified, the project will require re-assessment against the correct BREEAM criteria before the QA and certification process can progress. There may be additional charges associated with this process. Due to Simple Buildings not being a separate scheme, the audit level assigned to the assessment (Admin, Partial or Full) will follow the standard approach, i.e. previous audit records for that building type will be reviewed. Also, QA response times are the same as for other assessments of the same building type.

Simple Buildings – Shell & core assessments - KBCN00026

Registrations for assessments applying the simple buildings criteria to shell & core developments are not permitted. These are incompatible because the shell & core criteria are already simplified. 
15 11 17 Applicability to UK NC 2011 removed - see separate guidance under KBCN0397
 

Simple Buildings – Use of BMS - KBCN0948

Where a building does not require complex controls, but a BMS is installed primarily for its monitoring capabilities, this does not preclude assessment using the simple buildings criteria set. Buildings which require complex control systems cannot be considered as simple.  

Soft Landings Framework - KBCN1263

Embedding the principles of the Soft Landings Framework within a project can be used to demonstrate compliance with various aspects of the BREEAM criteria, particularly the Management issues.

Time critical requirements – Concept / Technical Design stages - KBCN1711

The intent of the criteria relating to project stages in BREEAM is to ensure that actions are taken at a time when they can have the intended influence. Where projects are following these defined stages via a traditional procurement route, referring to the project programme and work stages are a robust and convenient way to demonstrate that the intent is met. However, not all projects will follow these work stages. In such cases, the project can show that the intent is met by demonstrating that, for the relevant BREEAM requirement, the activity has happened when the project is at an appropriate stage of development. Concept Design The project stage at which fundamental aspects of the design are developed. Technical Design Once a detailed planning application has been submitted, many aspects of the design will be fixed, and the project is at Technical Design stage. Depending on the procurement route, there may be an overlap between technical design and the construction phase of the works. Additional guidance Sometimes different aspects of the design might be at different project stages. KBCN1156 gives detailed guidance on how to define the project stage for each construction element, based on the design information available for that element. Although it was originally written specifically to address Mat 01 LCA for UK NC 2018 and V6, it may be useful in other situations.

Time critical requirements – defining project stage by construction element - KBCN1156

This KBCN was originally written to specifically clarify BREEAM requirements for Mat 01 Concept / Technical Design under NC 2018 and V6. However, the general principles may also be applicable to other assessment issues. As a building design process passes through successive work stages, increasingly more aspects of the design become fixed. BREEAM criteria often require actions at, before or after specific project work stages, as these are the optimal stages to achieve the required sustainability outcome. When undertaken at a different stage, the criteria may be difficult to comply with, opportunities may be missed, options limited or costs may become prohibitive. Knowing which stage your project is at Where possible, BREEAM refers to industry-standard work stages, for example the RIBA plan of work stages. However different project teams can interpret these referenced stages differently. Furthermore, many projects do not follow these stages in a simple linear fashion for all aspects of the design at the same time. For instance, the envelope design may be well advanced even to the point where installation has commenced before any specification decisions have been made on some interior finishes. As such, a project may not be at one project stage for all elements of the design at any one point in time. This Knowledge Base compliance note is intended to provide supplementary information to enable projects to determine what stage they are at with respect to time critical BREEAM requirements, including where different elements are at different stages. Although project team members may be willing to offer their opinion on the stage the project has reached, this will often be subjective and hence inconsistent. Therefore, the process set out here looks at the currently available design information for the project (e.g. drawings, specifications) to determine the current work stage in relation to the issue under consideration. This provides a more objective, demonstrable approach for the assessor to follow. Concept Design Stage The RIBA definition of ‘Concept Design’ (RIBA stage 2) can be found here https://www.ribaplanofwork.com/PlanOfWork.aspx . The core objective given is ‘Prepare Concept Design, including outline proposals for structural design, building services systems, outline specifications and preliminary Cost Information along with relevant Project Strategies in accordance with Design Programme. Agree alterations to brief and issue Final Project Brief.’ Table 1 and table 2 (in the link below) provide further guidance, specific to BREEAM, to help determine whether a project, or part of the project relevant to the issue/credit, is at ‘Concept Design’ stage. If there is ambiguity or uncertainty about the stage of the project, the assessor should check with the design team whether the design documentation (drawings, specifications, BIM etc.) currently being produced by the design team will generally include the information listed. It is possible for different aspects of the project to be at different stages in terms of how progressed the design is. For example, the substructure design may be at technical design or even installed while the internal partitions are still at concept design. Whether this matters depends on the issue/credit being pursued. The following steps take this into account. Step 1 First, for the issue/credit being pursued, determine which of the relevant assessment scope items in table 1 and 2 are relevant. For example, if the issue/credit only relates to substructure, then only the substructure assessment scope items shall be considered. If the issue/credit is of a general nature concerning the whole project, then all the assessment scope items shall be considered. Step 2 For the relevant assessment scope items from step 1, decide which of the following applies the most: - Please note that the items listed are indicative of the typical information produced at ‘Concept Design’ stage. Technical Design Stage The RIBA definition of ‘Technical Design’ (RIBA stage 4) can be found here https://www.ribaplanofwork.com/PlanOfWork.aspx . The core objective provided is ‘Prepare Technical Design in accordance with Design Responsibility Matrix and Project Strategies to include all architectural, structural and building services information, specialist subcontractor design and specifications, in accordance with Design Programme.’ The following provides further guidance, specific to BREEAM, to determine whether a project is at the ‘Technical Design’ stage: The RIBA plan of work definition of ‘Technical Design’ clearly states that it should ‘…include all architectural, structural and building services information, specialist subcontractor design and specifications…’. Therefore, it is a simpler task to determine whether the project, or part of the project relevant to the issue/credit, is at this stage. If there is ambiguity or uncertainty about the stage of the project, the assessor should check with the design team whether the design documentation (drawings, specifications, BIM etc.) currently under production by the design team (and the contractor’s specialist sub-contractors, if applicable) will, when finished, generally include all the final design information required for the construction works on-site. Like concept design, it is possible for different aspects of the project to be at different stages in terms of how progressed the design is. The following steps take this into account. Step 1 First, for the issue/credit being pursued, determine which of the relevant assessment scope items are relevant (the assessment scope items given in table 1 and 2 may be used, but the rest of the information in these tables relates to concept design). Step 2 For the relevant assessment scope items from step 1, decide which of the following applies the most: - KBCN1156_IndicatorTables
