After receiving a planning application, the process of preparing building regulations and detail design documents typically involves several steps to ensure compliance with local building codes and regulations. Here's a general overview of the process:

​

1. Review Planning Application: The first step is to review the planning application that has been submitted. This includes examining the proposed development plans, site layout, architectural drawings, and any other relevant documents submitted as part of the planning application

2. Identify Building Regulations Requirements: Next, the building control officer or team will identify the specific building regulations that apply to the proposed development. Building regulations cover various aspects of construction such as structural integrity, fire safety, accessibility, energy efficiency, ventilation, drainage, and more.

3. Prepare Building Regulations Drawings: Based on the planning application and the identified building regulations requirements, the architectural and engineering team will prepare detailed drawings and specifications that demonstrate compliance with the building regulations. These drawings may include floor plans, elevations, cross-sections, structural calculations, insulation details, fire safety measures, and other relevant information.

4. Prepare Bespoke details, schedules and construction information: It is important to note that the building regulations document is not the same as the construction details and schedule. If the project includes bespoke details and build-ups, further details, visualisations, and specifications, windows and door schedule, wet room blow ups, reflected ceiling plans amongst other documents need to be developed to address the project's needs. These details, along with NBS specifications and, in some cases, bills of quantities, are needed to achieve more reliable tender documentation.

5. Consultation and Coordination: During the preparation of building regulations documents, there may be a need for consultation and coordination with various stakeholders such as architects, engineers, contractors, and building control officers. This ensures that all parties involved are aligned with the requirements and that any potential issues are addressed early in the process.

6. Submission of Building Regulations Application: Once the building regulations documents are prepared, they are submitted to the relevant building control authority or local authority for approval. This submission typically includes the detailed drawings, specifications, and any other supporting documentation required by the building control authority.

7. Review and Approval Process: The building control authority will review the submitted documents to ensure compliance with the applicable building regulations. They may request additional information or revisions if necessary. Once satisfied, they will issue a building regulations approval or conditional approval, allowing the construction to proceed.

8. Implementation and Inspection: With building regulations approval in hand, construction can commence according to the approved plans and specifications. Throughout the construction process, building control officers may conduct site inspections to verify that the work is being carried out in accordance with the approved building regulations documents.

9.  Final Certification: Once construction is complete, a final inspection will be carried out by the building control authority to ensure that the building meets all relevant building regulations. Upon successful completion of the inspection, a final certification or completion certificate will be issued, indicating compliance with the building regulations.

​

It's important to note that the specific requirements and procedures for preparing building regulations documents may vary depending on the location and jurisdiction. Therefore, it's essential to consult with the relevant building control authority or regulatory body for guidance throughout the process.
