Roof Top Working

Safe working is the key to successful projects. When our client approached us to strip out an existing telecommunications cabin and install new power, lighting, telemetry, ventilation and broadcast equipment, it seemed like it would be business as usual until we realised this cabin was on the roof of a five story building.

The roof was accessed from a vertical access ringed ladder from the top landing of the buildings access stairwell. Apart from tooling and small items of equipment, which we could raise in the normal way through the vertical ladder hoops (see Lift Motor Room case study) the stripped out equipment and new equipment would need to be craned off, and onto, the roof.

Preparation works were carried out, by our roof top trained and accredited team, ahead of the cranes arrival. This included the removal of such items as telecommunications equipment racks and electrical infrastructure, along with de-gassing of redundant air conditioning units (carried out by our partners at Advantage Air under our supervision) prior to us removing them from the cabin. All stripped out equipment was carefully stowed, ready for transporting to the carpark below later in the build. The cabin was prepared with new apertures, with temporary seals ready for the new ventilation system to be installed.

In conjunction with the crane operator and the building management, the drop zones were safely maintained and our staff directed the crane operator, positioned on the ground, to collect and lift the roof top loads and deliver the new equipment without a hitch. All the lifting was completed on a Sunday and allowed our team to complete the build on time and within budget.
