Clear-Span Steel Warehouse, Nairobi

A pre-engineered clear-span steel warehouse taken from bare site to a finished, weather-tight building.

Project overview

Roleko constructed a clear-span steel warehouse in Nairobi, from bare site to a finished, weather-tight building. Steel portal frames span the full width without internal columns and are clad in profiled steel sheeting above a reinforced concrete plinth wall.

Scope of works

  • Reinforced concrete pad foundations with cast-in holding-down bolts and ground beams
  • Fabrication and erection of portal frames, purlins, side rails and bracing, including final alignment
  • Cast in situ reinforced concrete plinth wall between the steel columns
  • Ground floor slab cast in bays with saw-cut joints and a power-floated finish
  • Profiled steel roof and wall cladding with roof lights, flashings and steel sliding doors
  • Masonry boundary wall with security topping

Capability demonstrated

Structural steel erection, in situ concrete works around an erected frame, safe working at height, and delivery of a complete building to a clean, finished standard.
