Multidisciplinary projects in Bahrain often need a specialist design input that a generalist team does not hold in-house, such as ELV systems, fire and voice design, or building management. A specialist subcontractor can provide that input, provided the interfaces with the lead consultant are clear.
## Define the interface
The lead consultant should set out what the subcontractor designs, what it coordinates, and what it must not change. Agree the boundary with architectural, structural and MEP drawings in writing.
## Set quality review points
- Design review by the lead engineer before each issue. - A revision log linking each change to the architectural or MEP revision that triggered it. - Clash resolution agreed in the coordinated model.
## Common mistakes
- Subcontractors designing against outdated base drawings. - Unclear ownership of coordination clashes. - Specialist deliverables issued without the lead consultant's sign-off.
