The erection company will be in contact after an order is placed to advise on scaffolding requirements. They will generally require scaffolding to be erected around three sides of the building before they arrive on site. The scaffolding company will then return to complete the installation once the erectors are at first floor level. The scaffolding can be erected far enough away from the frame so that it can stay up and be used by the other services such as brick layers and roofers. The erectors will organise themselves and include for in their quoted price any mechanical handling required on site and their own accommodation whilst working on the installation.
