Construction drawings

Before work can start on site youarchitectural designer will need to produce a set of drawings that comply with the building regulationsS/he will gather this information from key trades/suppliers and other advisors such as the structural engineer, but will mostly draw the plans up from their own detailing, based on the non-technical planning drawings that were submitted to the authorities to get planning permission.  

Construction drawings include all detailing for structural components as well as every layer of certified product that is to be installedincluding manufacturer specifications for things like windows and doors, insulation, airtightness and thermal bridging details as well as how ventilation units and ducts are to be installed.Specialist suppliers may provide their own set of drawings for each of these details; this is especially common in the case of ventilation. Electrical points will also be included with specialist drawings for these, usually drawn up by the architectural designer to give to the electrician.
