Construction drawings provide accurately measured and detailed drawings of a resolved design, and its parts, to guide the contractor in its construction. They may be subject to clarification, but should be complete with dimensions, details, and notes to enable construction without the need for additional information. They also provide the detailed information required for building permit and, if required, tendering purposes. This stage requires building permit approval. This stage requires that we liaise with (structural, civil, building surveyors,) consultants.
