Following several reported roof leaks IKO were chosen to survey the Academy roofs and recommend a proposal for renewing the aged and weathered membrane this included many non-compliant and fragile roof lights.

ISSUES IDENTIFIED

Height of the building and anticipated scaffolding costs. The main roof was covered with paving slabs laid on minimal insulation. The IKO survey found the roof to be saturated and therefore had to be fully stripped.

The insulation in the existing system was external to the asphalt, core sampling found that the concrete deck was laid flat with Lytag to form falls.

The roof would be open and exposed to extreme weather conditions due to height and location. It was estimated it would cost excess of 450k to scaffold the building, the scaffolding was to include a roof and side sheeting to protect the site from the weather and allow works to continue despite of weather conditions.

Once the removal of the asphalt had begun it became clear the concrete deck was in a poor unstable condition and would require stabilizing products before the new weatherproofing could be laid.
