Why Design+Build works in the Cayman Islands — and where it fails

Design+Build is not a procurement model. It is a relationship model. Its value comes entirely from who holds the accountability — the architect or the contractor.

When the architect leads

Architect-led Design+Build works when the architect contracts directly with the client, selects and manages the contractor, and maintains the same documentation standard they would apply to any conventional project. The architect is responsible for both the design and its delivery — so there is no incentive to compromise the specification, and no one else to blame if the outcome falls short.

For the client, the benefit is a single point of accountability. One agreement. One firm responsible for everything from the first sketch to the handover certificate. No gap between what was designed and what was built. Programmes run shorter because design and construction decisions are made by the same team. Variations are fewer because the person managing the contractor is also the person who specified the work.

When the contractor leads

Contractor-led Design+Build is common in Cayman. A developer agrees a lump sum with a contractor, the contractor appoints an architect to produce the documentation, and the architect's primary obligation runs to the contractor — not the owner. The incentives are wrong from the first drawing.

The consequences accumulate quietly. The architect's drawings are produced to satisfy the contractor's programme and cost targets rather than the owner's design intent. Materials get quietly substituted. Specifications are reduced to meet the contractor's margin. The owner has no independent professional in their corner — and when defects emerge after handover, there is no one whose obligation is to pursue them.

This is not a theoretical risk. It is the most common source of client disappointment on Cayman construction projects.

The one question to ask

Before entering any Design+Build arrangement, ask one question: who does the architect answer to?

If the answer is the contractor, the client is unrepresented. If the answer is the client, the model delivers what it promises.

AED's Design+Build engagements are owner-direct. We select the contractor, manage the programme, certify the claims, and inspect the workmanship against our own drawings. The building that gets delivered matches the building we designed — because we are present to ensure it does.
