Crafting a Robust Building Warrant Application: A Comprehensive Guide

​

Annex C - Technical Checklist

​

Ensuring a successful building warrant application involves meticulous attention to technical details. The following checklist outlines essential technical items to consider when submitting your application:

​

Drawings:

​

• Location/Block Plan: Provide a plan identifying the site/building location.

• Site Plan: Include site levels, pathway gradients, and delineate the site boundary.

• Foundation Plan

• Floor Plans

• Roof Plan

• Elevations

• Building Sections

• Detail Sections and Plans: Illustrate the proposed construction of each building element.

• Services Layout: Include electrical layouts.

• Drainage Design and Layout: Specify surface water and foul drainage, along with relevant design calculations and system details.

• Existing and Proposed Drawings: If applicable, include drawings of both existing and proposed structures.

​

Drawing Convention and Annotation:

​

• Ensure each drawing has a unique reference number.

• Title each drawing appropriately and indicate the scale.

• Include a north point on plans.

• Clearly label new work as 'Building Warrant.'

• Provide clear, concise, and relevant notes on drawings.

• Refer to relevant specification references and include a key/legend.

​

Specification:

​

• Tailor the specification to the project, avoiding generic content.

• If referencing the National Building Specification (NBS), include only relevant sections.

• Maintain a focused specification relevant to demonstrating compliance.

​

Supporting Documentation:

​

• Include supporting certification/documents such as BBA certificates.

• Provide product/system technical approval and/or test data information if applicable.

​

Site:

• Include a site investigation report detailing ground conditions and existing drainage layout.

​

Structural:

​

• Refer to Technical Handbooks - Section 1 and confirm compliance intent.

• Preferably, provide a Certificate of Design for structural compliance.

• Include structural calculations if necessary, but note that this may increase processing times.

• Ensure co-ordination with other disciplines' drawings.

​

Fire:

​

• Refer to Technical Handbooks - Section 2 and provide a fire-engineered solution and fire strategy.

• Include relevant fire-related performance information.

​

Energy:

​

• Refer to Technical Handbooks - Section 6 and provide a Certificate of Design if applicable.

• Submit Standard Assessment Procedure (SAP) or Simplified Building Energy Model (SBEM) for relevant constructions.

• Include supporting calculations/evidence demonstrating thermal performance.

Note: Avoid repetition in drawings and specifications, and ensure clarity and coherence throughout the application process.
