Definition
Turnkey is a contracting method in which one party handles design, construction and finishing until the owner receives a building ready to use.
Why it matters on a project
It saves the owner coordinating many parties, but the finish level and specifications must be defined precisely so 'ready' is not read differently by each side.
Common mistake
Signing a turnkey contract with a general finishes description and no approved materials schedule.
Frequently asked questions
How is turnkey different from design and build?
Design and build may stop at shell or a defined finish; turnkey means a building ready to use.
How do I protect myself in a turnkey contract?
With an approved materials and specification schedule, payments tied to completed stages and a clear handover checklist.
