Construction Drawings

Architectural Drawings and Building Regulations

Before construction can begin, your architectural designer must produce a set of detailed drawings that comply with building regulations. These drawings are typically based on non-technical planning drawings previously submitted to obtain planning permission.

Information Gathering and Detailing

The architectural designer will gather necessary information from key trades, suppliers, and advisors such as the structural engineer. However, the bulk of the detailing will be drawn from their expertise. These construction drawings will include:

  • Structural components detailing
  • Specifications for certified products (e.g., windows, doors, insulation)
  • Airtightness and thermal bridging details
  • Installation guidelines for ventilation units and ducts
  • Electrical points, typically included by the architectural designer for the electrician

Specialist suppliers may also provide their own set of drawings for certain details, especially for complex systems like ventilation.

Compliance with Building Regulations

In Northern Ireland (NI), the building control officer requires a complete set of plans before construction begins to ensure compliance with current building regulations. In Republic of Ireland (ROI), these documents are necessary for filing your commencement notice on the Building Control Management System (BCMS).

Construction Drawings and Pricing

Construction drawings are crucial not only for regulatory compliance but also for obtaining accurate prices from trades. They serve as the basis for:

  • Structural engineers to calculate loads for items like steel beams
  • Assessing the need for structural supports for heavy fixtures (e.g., chandeliers, baths, jacuzzis)
  • Identifying the requirements for RSJs or steel beams for open spans

Ensuring Up-to-Date Drawings on Site

A procedure must be in place to guarantee that only the latest version of the construction drawings is available on-site at all times. This is essential to avoid errors and ensure that the build complies with the most current plans and specifications.
