Two government authorities — Ashghal, the Public Works Authority responsible for roads and infrastructure corridors, and Kahramaa, the Qatar General Electricity and Water Corporation — both impose requirements that reach into a building's telecoms design well before rack layout and patching schedules.
Ashghal's relevance is at the site boundary and external duct crossing level. Any project requiring external telecoms or fibre connectivity between a building and the public network must coordinate against Ashghal's Underground Utility Network (UGN) design guidelines, which set requirements for how crossing ducts connect with utility corridors and concrete protection beneath carriageways. In practice, the actual civil route needs to be verified against as-built utility records via an on-site survey, since records in a fast-developed city don't always match design intent.
Kahramaa's relevance is a structural decision with ripple effects: Kahramaa strongly prefers, and frequently mandates, that main electrical rooms sit on the ground floor, with room layout requiring Kahramaa sign-off before construction. Telecoms/IT room adjacency planning needs to accommodate a room whose exact footprint isn't finalised until Kahramaa approves it.
Design guidance
Engage Ashghal's UGN requirements at masterplan or site-boundary stage. Commission an as-built utility survey before finalising external duct routing. Sequence telecoms/IT room layout finalisation after Kahramaa's electrical room siting approval where the two rooms are adjacent.
| Authority | What it governs for cabling projects | Design stage to engage |
|---|---|---|
| Ashghal | External duct crossings, utility corridor allocation | Masterplan/site boundary, before detailed design |
| Kahramaa | Ground-floor electrical room siting | Early architectural coordination |
| Building operator/IT | Internal structured cabling standard | Detailed design, following the above two constraints |
Common mistakes
The most common mistake is finalising internal cabling routing before external civil coordination with Ashghal is complete. A second is treating Kahramaa's electrical room requirement as fixed and known early, when its exact position depends on Kahramaa's own approval process.
Future outlook
As Digital Agenda 2030 pushes higher-capacity digital infrastructure, both authorities are digitising their infrastructure records, which should reduce the as-built discrepancy problem over time.
