Fit-Out MEP Coordination
By Dhruv Agarwal · · 2 min read
What we deliver
HVAC, electrical, plumbing, firefighting, low voltage and networking coordinated into the fit-out — designed against the actual layout rather than inherited from the base build and hoped to still work.
This is the package that decides whether a finished office is comfortable. It is also where the majority of fit-out delays and post-handover complaints originate, because it sits at the interface between trades that are usually contracted separately.
What changes when a floor is subdivided
| Base build assumes | Your layout does | Consequence |
|---|---|---|
| Open plan | Cabins and meeting rooms | Sprinkler heads relocated per enclosure |
| Even cooling load | Rooms with different occupancy | HVAC zoning and rebalancing |
| Free return air path | Walls to slab | Transfer grilles or ducted return |
| Uniform lighting grid | Task-specific zones | Circuits and controls redesigned |
| Generic small power | Desk and equipment positions | Floor boxes and containment reset |
| Open detection coverage | Enclosed rooms | Detectors added per compartment |
Scope of works
| Discipline | What we deliver |
|---|---|
| HVAC | Zoning, ducting, diffusers, VAV, rebalancing and commissioning |
| Electrical | DB, circuits, small power, containment, floor boxes |
| Lighting | Layout, fittings, controls, emergency lighting |
| Plumbing | Pantry, washroom and wet area services |
| Firefighting | Sprinkler relocation, detection, alarm coverage |
| Low voltage | Access control, CCTV, PA, BMS interfaces |
| Networking | Structured cabling, racks, outlets |
Where projects go wrong
- HVAC never rebalanced after subdivision. The single most common cause of comfort complaints in a new office.
- Return air path blocked by partitions to slab. Supply is fine, return is not, and the room feels stuffy despite cold air arriving.
- Sprinkler coverage not reassessed. Every enclosed room needs coverage in its own right under NBC 2016 Part 4.
- Detection coverage missed in new rooms. Compartments created by the fit-out need their own detection.
- Containment undersized. Data cabling grows; a tray sized exactly for day-one count means the next change is a rebuild.
