Making a quality building warrant application: what you need to know
This guidance provides useful information on how to make a good quality building warrant application.
This document is part of a collection
Annex C - Technical Checklist
The following technical items should be considered when making a building warrant application.
The Procedure (Scotland) Regulations 2004, schedule 2, sets out the which information should accompany an application. The Procedural Handbook provides further information.
- Location/Block plan
It is essential that a plan identifying the location of the site/building is submitted.
- Site Plan
Include site levels, pathway gradients and identify the site boundary.
- Foundation plan
- Floor plans
- Roof plan
- Building sections
- Detail sections and plans
Provide details to illustrate the proposed construction of each element of the building.
- Services layout
For example, electrical layouts.
- Drainage design and layout
For example, surface water and foul drainage. Include, where relevant, design calculations and system details.
- Existing and proposed (if relevant)
If work relates to an existing building include drawings of both the existing building and proposed.
Drawing convention and annotation
- Each drawing should have a unique reference number
- Title each drawing Drawn to a suitable scale Consider including a scale bar on drawings and refer to the Procedural Handbook for the suggested scale of different drawing types
- North point on plans
- Clearly identify new work Label/stamp drawing as ‘Building Warrant’
- Clear, concise and relevant notes on drawings
- Refer to relevant specification references or documents Indicate spaces/dimensions related to compliance with building regulations For example, activity spaces, travel distances, clear opening dimensions etc.
- Provide key/legend
Note: Avoid repetition on drawings and specifications. Repeating the same notes or details across numerous drawings/documents can lead to issues with consistency, especially when revising information for resubmission.
- Project specific
Avoid a generic specification, ensure it is specific to the project.
If submitting National Building Specification (NBS) – avoid submitting the full document, only include/reference the NBS section/clause that is relevant to demonstrating compliance.
- Focused specification
The specification should be relevant to building warrant with a focus on demonstrating compliance.
- Supporting certification/documents
For example, BBA certificates or similar.
- Product/system technical approval and/or test data information
Provide product technical information if relevant to demonstrating compliance with the building regulations.
- Site investigation report
- Ground conditions
- Existing drainage layout / Scottish Water consent
Technical Handbooks – Section 1
- Certificate of Design This is the preferred route for demonstrating compliance of structural design. It is the most efficient method as the verifier is not required to check the design.
- Structural calculations Note that submission of calculations can increase processing times as verifiers need to check the information.
- Small Buildings Structural Guidance (SBSG)
Ensure, for example, architectural, structural, drainage and services drawings are all co-ordinated.
Note: The structural design should be clearly illustrated. Avoid over marked drawings to show this.
Technical Handbooks – Section 2
- Fire engineered solution
- Fire strategy
Demonstrate how the proposed fire strategy for the proposed building will demonstrate compliance with the building regulations.
- Fire related performance information
Technical Handbooks – Section 6
- Certificate of Design
If a certifier of design has been used
- Standard Assessment Procedure (SAP)
Required for new dwellings and some other defined construction work.
- Simplified Building Energy Model (SBEM)
Required for new non-domestic buildings and some other defined construction work.
- Supporting calculations/evidence
Include calculations, or other documentation, that demonstrates the thermal performance being achieved by the various aspects of the fabric of the building, for example, wall U-value calculations.
Note: This list is not exhaustive. An example of technical handbook sections are given in the checklist, as these highlight the most common areas where information is often missing from a submission. The information submitted with a building warrant application must demonstrate compliance with all sections of the technical handbooks.
