A fit-out brings many trades into the same space. Coordination is what stops them blocking each other. This guide explains the interfaces that matter and how conflicts are caught early.
Where trades meet
- Partitions, ceilings and the lighting and services above them.
- Electrical and plumbing routes against joinery and finishes.
- Flooring, wall finishes and painting, which must follow a clean sequence.
- Specialist work, where it applies, such as air conditioning or fire systems, which needs its own coordination.
What happens when trades work from different information
They build to different versions of the plan. One trade cuts what another has just fixed, and someone pays for the correction. A single current set of drawings, shared with everyone, prevents most of this.
Who identifies coordination issues
Ideally the party responsible for the whole scope, supported by every trade raising conflicts as soon as they see them. A short coordination meeting before each phase is often enough to surface clashes on paper instead of on site.
When to escalate
If a conflict affects safety, another trade critical path or a decision that belongs to the client, escalate it at once with the facts and options instead of letting each trade solve it separately.
Protecting completed finishes
Sequencing so that dusty and wet work finishes before delicate surfaces go in, and protecting completed areas, reduces damage and the snagging list at the end.
Questions clients ask
Who is responsible for coordinating the trades?
It depends on the contract. With one contractor it is that contractor; with separate trades it must be assigned explicitly.
Can sequencing really reduce damage?
Yes. Doing dusty, wet and heavy work first and delicate finishes last keeps completed areas clean.
How SADEED coordinates trades
Under Design & Build, SADEED coordinates the trades through one project manager and one current set of information, including specialists where the project needs them.
