Delivery Model 01

Design-Bid-Build (Traditional)

The traditional procurement route — separate design and construction contracts under FIDIC Red Book and national frameworks.

Traditional Procurement

Sequential. Predictable.

In the Design-Bid-Build (DBB) model, the client first appoints a designer to develop a complete design, then tenders the construction package separately. CONTECH bids and delivers the construction portion as principal contractor under a fixed-price, fixed-time arrangement.

This is the most established procurement route for public sector projects in the UK, the Western Balkans and across donor-funded works. It is the default route under FIDIC Red Book and most national public procurement laws.
