Single-source design and construction delivery under FIDIC Yellow Book — faster delivery, single point of accountability.
In the Design & Build (D&B) model, CONTECH takes contractual responsibility for both design and construction under a single agreement with the client — typically structured under FIDIC Yellow Book.
This model accelerates delivery by overlapping design and construction phases, reduces interfaces between professional teams, and gives the client one accountable party for the outcome. It is widely used for industrial, commercial, energy and infrastructure projects across the EU and donor-financed sectors.
