MEP case study · Leisure
Themed Attraction — Services in Sculpted Geometry
Riyadh, Saudi Arabia · 2024 · Main contract
Scope
MEP coordination with architectural elements
Zones
Multiple themed environments
Programme
16 months
Interfaces
Ride systems, GRC/GRP, lighting, fire, HVAC
Services routed through sculpted composite geometry with no repeating grid — coordination carried out in the model because there were no flat surfaces to measure from.
01 — Coordination
Services routed through geometry with no repeat
Every duct, sprinkler drop and cable route was placed inside the sculpted composite model, so penetrations were cast into panels in the workshop rather than cut on site.
- Laser survey of structure before composite panels were modelled
- Service penetrations cast into panels at manufacture
- Ride-system clearances treated as fixed no-go volumes
- Access hatches designed as part of the themed surface
02 — Plantroom
Back-of-house built to carry the show
Plant and distribution were sized for peak guest load and show conditions, with routes kept entirely out of guest sightlines.
- Plant sized for peak occupancy and show-effect loads
- Distribution routed behind themed surfaces with maintained access
- Vibration and acoustic isolation for plant adjacent to guest areas
- Riser and containment set out against the surveyed structural grid
03 — Commissioning
Tested against show conditions
Systems were commissioned under simulated show and peak-occupancy conditions, with fire, smoke control and effects interlocks tested together rather than in isolation.
- Smoke-control and cause-and-effect testing with effects running
- Cooling verified at peak occupancy and full lighting load
- Show-control and BMS interfaces proven end to end
- Snagging closed zone by zone ahead of the public opening
04 — Handover
Opened on the fixed public date
Operations received a documented, tested building with maintenance routes that survive the theming — the difference between a set and an operating attraction.
- As-built model including concealed service routes behind theming
- Maintenance access map issued with the O&M package
- Operator and technician training delivered before opening
- Aftercare team retained through the first operating season
Services that close the ceiling,
and the programme.
