Service Routing
Horizontal and vertical routes agreed against the structure, with riser and ceiling space allocated per trade.
- Riser and shaft allocation
- Ceiling void distribution
- Horizontal route agreement
MEP Coordination
MEP Coordination in Lebanon
Mechanical, electrical, plumbing, HVAC, fire-fighting and low-current systems coordinated against the structure before it is poured.
Services & Systems
Agreed before the pour, not cut after
Every service in a building needs a route, and every route needs a hole in something. When those holes are agreed before the slab is poured, they are free. When they are not, someone is coring through a finished structure, weakening it, and arguing about who pays.
Coordination means overlaying the mechanical, electrical, plumbing, HVAC, fire-fighting and low-current layouts against the structure and the architecture, then resolving the conflicts while they are still lines on a drawing.
Scope of works
Openings & Sleeves
Penetrations marked on the structural drawings and cast in, so nothing is cored through a finished element.
- Cast-in sleeves and box-outs
- Structural approval of penetrations
- Setting-out before the pour
HVAC & Plumbing
Ductwork, drainage falls, and pipework coordinated so gravity systems keep the falls they need.
- Ductwork routing and plant space
- Drainage falls and gravity runs
- Plant and equipment access
Fire-Fighting & Low Current
Sprinkler, fire alarm, data, and security containment coordinated with the other services in the same void.
- Sprinkler and fire alarm layout
- Data and security containment
- Containment and tray coordination
Testing & Commissioning
Coordination of testing and commissioning across trades, with records issued at handover.
- Pressure and continuity testing
- Commissioning coordination
- Records and O&M handover

Coordination on Lebanese projects
Backup power, water storage, and solar are near universal requirements on Lebanese projects, and they all need space and structural support planned early rather than found later.
