MEP services
Mechanical, electrical and plumbing — everything that happens in the six hundred millimetres above a ceiling nobody ever looks at. It is the package that decides whether a building is comfortable, compliant and cheap to run.

The void is the project
Four services, one section, no room
We offer comprehensive MEP services that cover the full spectrum of mechanical, electrical, and plumbing systems. Our expert team ensures that all systems are designed and installed to the highest efficiency standards, providing safe, reliable, and energy-efficient solutions for every project.
Duct, pipe, cable tray and sprinkler all have to cross the same ceiling void, and each has rules about what it may pass under, what gradient it needs and how much room it needs to be maintained in. Coordinate them on a drawing and it is an afternoon. Coordinate them on site and it is a week per crossing, a lowered ceiling, and a conversation with the client about why the room is shorter than the brochure said.

Everything is decided in a section
The coordinated section is the single most valuable drawing on an MEP package. It fixes what crosses above what, it proves the ceiling height, and it is the document that stops four subcontractors each believing the void is theirs.
- A coordinated section per corridor and per riser, not one typical section that is true nowhere
- Clear ceiling height proved from the slab soffit down, with the deepest crossing in it, before the height is promised
- Maintenance access allowed for in the section, because a valve nobody can reach is a valve nobody will service
Mechanical takes the room first
Ductwork is the biggest thing in the void and the least able to move, so it is routed first and everything else is routed around it. A duct that has to bend to avoid a pipe has lost performance the fan now has to pay for.
- Routed first, and routed straight — every avoidable bend is pressure drop, which is fan energy for the life of the building
- Load calculated against the real envelope, taking the glass specification from the facade package rather than a rule of thumb
- Fire dampers at every compartment line, accessible, and recorded on the as-built where the next contractor will look
Pipework has gradients and cannot negotiate
Water goes where gravity sends it. Drainage falls are the one constraint in the void that cannot be value-engineered, which is why they are set before anything flexible is routed.
- Falls set before the flexible services, because a drain that has lost its gradient is a defect with no cheap fix
- Pressure-tested before being covered, section by section, with the test recorded against the section
- Thermal insulation and vapour control on chilled lines, continuous through supports — a bare bracket is where the condensation starts
Power, data and the things that must work in a fire
Electrical is the most forgiving service to install and the least forgiving to get wrong, because the parts that matter most are the parts that only ever run once.
- Containment sized for the future, not for the cable schedule on the day — a full tray is the first thing the next fit-out curses
- Segregation maintained between power, data and fire-rated circuits, through every crossing
- Life-safety systems designed to the approved fire strategy and tested as a system, not as a set of devices
- Civil Defence approval is obtained before the municipal licence is issued — the fire-safety drawings go up with the submission, not after it.
Then the ceiling closes over all of it
The last act of an MEP package is becoming invisible. What remains visible — a diffuser, a sprinkler head, a light — lands on the ceiling grid, which means the MEP setting out and the architectural setting out have to be the same drawing.
- Terminals set out on the reflected ceiling plan, from the architect’s datum, not from the duct centreline
- Nothing buried untested: every covered section signed off before the ceiling goes up
- Access hatches located and scheduled, so the first maintenance visit does not begin with a saw
How an MEP package runs
Six stages, ending in a witnessed record
The deliverable of an MEP package is not the installation. It is a set of signed test results that prove the installation does what the design said it would.
Design and load calculation
Loads calculated against the real envelope and the real occupancy, not against an area rate.
Coordinated sections
Duct, pipe, tray and sprinkler resolved in section per corridor and riser, with maintenance access in it.
Civil Defence approval
Fire strategy, detection and suppression approved before the municipal licence is issued.
First fix
Containment, ductwork, pipework and cabling installed and pressure- or continuity-tested before being covered.
Second fix and terminals
Terminals, fittings and devices set out from the architectural datum on the reflected ceiling plan.
Testing and commissioning
Balancing, functional testing and integrated system tests, witnessed and signed, then O&M and as-builts.
Scope

- Ongoing maintenance after the defects liability period
What you should ask any MEP contractor
Three questions, and our answers
We do, in section, before first fix. One coordinated section per corridor and riser, with the deepest crossing drawn and the maintenance access in it.
We do. The fire strategy and life-safety drawings go to Civil Defence as part of the submission, because approval there is a condition of the municipal licence, not a step after it.
The commissioning engineer, witnessed, per system — and the records are handed over as a set, with the as-builts that match them.
Early Involvement
Bring the contractor in while the design can still change. The cheapest decision on any project is the one taken early.
Send us the architectural set and the occupancy figures.
That is enough to calculate the load honestly, which is where every MEP price should start.
