How do you verify interface coordination competency in Borama?

Interface coordination competency in Borama is verified by documents and site walks, not by claims. Ask a contractor to name the interfaces on a past job, then produce the signed inspection that closed each one. A firm that coordinated trade packages keeps clash checks, hold points and handover records with dates and names. A firm that only attended meetings has none, and the gaps show up later as rework at the joints.

What does interface coordination cover on a Borama build?

Interface coordination makes the joints between trade packages work. On a typical Somaliland building, the joints include setting out and excavation, foundation and blockwork, slab and services, blockwork and plaster, plaster and tiling, roof structure and ceiling, and external drainage against finished ground levels. Each joint has a tolerance, a sequence and a point where one trade must stop and the next must start. Coordination is the set of checks and records that hold those points together. Ask the approving authority for the project which submission and inspection requirements apply to a build of your size. Ask the contractor to describe one interface from a past job: who set the level, who checked it, what was written down, and where the record is now.

How do gaps between trade packages show up on site?

Gaps between trade packages appear as rework, delay and arguments about who pays. The mechanism is simple. No one owns the joint, so the first trade sets a tolerance that suits itself, the second trade arrives and finds the work does not fit, and the client hears two versions of what was agreed. The failures to check for are the same on any project: a slab edge out of level before blockwork starts, a plaster line that leaves tiles too thin or too thick, a ceiling grid that fights the roof purlins, or a drainage invert above the finished ground level. The cost lands as cutting, filling, extra material and idle crews. Ask for the method statement for each joint. If a contractor cannot describe the hold point and the sign-off at a joint, that joint is unowned.

How do you test a contractor's coordination claims?

Test coordination claims by sampling recent work and reading the records, not the CV. Pick three or four interfaces from a completed or nearly completed job and ask for four things: the dated inspection or check sheet, the name and role of the person who signed it, the method statement for that joint, and the contact for the next trade. Then walk the site with the contractor and check whether the built work matches what the records say. Look at whether the contractor kept a drawing register, a request-for-information log and a snag list that was closed out. Ask the client reference if they would use the same firm at a joint-heavy stage again. If the records do not exist, treat the coordination claim as unverified and price the risk into your programme and supervision budget.

What to do next

Before you sign, select one interface from your own drawings and ask each bidder to submit the method statement, inspection sheet and a reference for a similar joint on a past job. Compare the documents side by side, then walk one recent site with the shortlisted firm and ask to see the signed records on file. Confirm all inspection and submission requirements with the approving authority for the project.
