- Required works: 1. Visual and physical barriers to 2no ~8x6m sections of roof Three sunken areas of roof have been patched and waterproofed from above. We now need visual and physical barriers to these areas to stop anyone walking from above. Two ~8x6m areas to be barriered off

Requirement: - Paint: Hazard striped paint (yellow and black diagonal lines) to 8x6m area of roof - Barriers: Chain barriers around perimeter, 2 rows, suitable for high winds. - Signage: "Danger, Keep out, fragile roof" signage, or similar

2. Steel re-enforcement to underside of 1 off 4x4m section of steel decking One sunken area of roof has visible deterioration on the steel decking underside. Whilst no one will be walking from above, we want additional strengthening to this area, to mitigate risk of collapse from e.g. snowfall, while also keeping the ability to visually inspect from below.

Requirement: - Clean and paint: Clean up and fire proof painting of existing deteriorated area of underside steel decking (approx. 2x3m) - Brackets: Mount several brackets from either steel beam, laid between the ridges, spaced at ~200mm intervals (or alternative suggestion), taking care not to pierce the roof membrane

3. Repair unadhered membrane to upstand. A large area of unadhered roofing membrane is present at the upstand. We now need this to be repaired. Approx 8 x 2m area, to mitigate risk of water ingress and damage to roof.

Requirement: - Repair: Remove old felt membrane and lay new

4. Level out flood-prone area An approx. 12x1m area is prone to flooding. We require this to be levelled out so the water flows out of the area

Requirement: - Works to level out the area to avoid it flooding during heavy rainfall
