Design and estimate documentation is the complete set of drawings, calculations and cost estimates from which a building is constructed. Without it, you cannot obtain permits, calculate the budget accurately or control the quality of work.
Main sections
- Site master plan — building location, access roads, landscaping;
- Architectural design — floor plans, elevations, sections;
- Structural design — foundations, frame, calculations, including seismic analysis;
- Building services — water supply, sewerage, heating, ventilation, power supply, low-voltage systems;
- Construction management plan — sequence and timing of works;
- Cost estimate documentation — the cost of construction.
Design stages
A project is usually developed in two stages: first the key design decisions and expert review, then working documentation for the builders. For simple buildings the stages are combined.
How design documentation saves money
- The budget is known before construction starts.
- Contractors are compared against a single scope of work.
- Fewer reworks and “unforeseen” costs.
The company’s design department develops design and estimate documentation for industrial, civil and private projects, supports the expert review process and provides designer’s supervision.
