Crossrail – Liverpool Street

6 to 7-storey commercial office buildings, with demolition on a floor-by-floor basis using 7-ton excavators with specialist attachments to reduce noise whilst breaking through heavily reinforced concrete.

Moorfields Building – the Metropolitan Line tunnel was immediately beneath the basement slab. Noise, vibration, and movement was a key issue and had to be continuously monitored. Our methodology and management ensured that all LUL assets remained protected throughout the project.

Moorgate – we designed and installed a full protection deck over the live underground station ticket hall, to ensure public safety and installed a tower crane which significantly improved the site logistics due to space being at a premium. Steelwork insulated in 50mm of sprayed asbestos in good condition was found, as were the stations supporting steelwork – 4 x 100m beams each of 2.5m high and all ancillary steelworks. The sprayed coating was removed under fully controlled conditions in individually constructed enclosures.

Blomfield Street – designed and installed a deck to protect the above-ground section of the Metropolitan Line tube and support the demolition scaffolding to the building. Materials were discharged internally, via a conveyor system removing debris up to a first-floor disposal gantry in Blomfield Street.

The asbestos removal was on a 24/7 working regime maintained over a 12-week period, with the total amount of asbestos waste being approx. 875m3 (25 x 35m3 skips).

The HSE visited the site during removal, the largest they had seen for many years & were pleased with its management.

Working on live London Underground infrastructure.

Significant interface between John F Hunt, members of the public using the station users and operational staff.

Controlling 24-hour working, movements and noise in consideration of the adjacent residents and local community.

All projects were completed on time and within budget.
