Written by RCG Consultants
In a traditional tender, the client supplies a completed design and contractors price it. In a Design & Construct (D&C) contract, the contractor takes responsibility for both the design and the construction. For electrical contractors, that changes what you price, what you are responsible for and how you manage risk.
What changes in the tender
Instead of pricing a finished set of drawings, you price against a brief or a concept design. The electrical design is not complete, so the estimate has to allow for design development, assumptions about loads and equipment, and the design documentation itself.
Where the risk sits
Because the contractor owns the design, errors, omissions and design changes that come from developing the design sit with the contractor. Clear assumptions and exclusions in your tender matter, as do clear records of what was in the client’s brief.
Design sign-off
Electrical design for a D&C project usually needs sign-off by a registered professional engineer. In Queensland, that is an RPEQ. Allow for the design fees and the sign-off in your tender, and confirm who is responsible for each part of the design.
