What a turnkey construction contract should include
A turnkey arrangement works best when the responsibilities of the client and contractor are clearly documented. The objective is not simply to use the phrase “turnkey,” but to define exactly what is included in the final handover.
Scope and drawings
The agreement should identify the approved drawings, BOQ or specification schedule and the boundaries of the contractor’s scope. Any client-supplied material or specialist work should be listed separately.
Material specifications
Define brands, equivalent-substitution rules, allowances and the approval process for finishes. If a brand becomes unavailable, the process for choosing an equivalent should be documented.
Milestones and programme
Major stages such as foundation, RCC, masonry, MEP, plaster, flooring, painting, interiors and handover should be part of the execution plan where relevant.
Variations
Changes requested after the agreed scope should be documented with commercial and timeline impact before execution whenever practicable.
Payments and handover
Payment milestones, invoice requirements, completion checks, snag closure, project records and warranty or defect-liability obligations should be stated clearly.
