Enabling works at New Covent Garden

A large enabling works project for at New Covent Garden for Vinci construction. The works involved carrying out various elements of asbestos works within the market to offices and units, demolition of the old Irish dock, partial demolition of a cantilevered canopy and removal of several high mast lighting towers to clear the way for the main works.

Additionally, we carried out a 23,000m2 ground stabilization and road formation project.

An Antigo breaker was used to break the vast slab area ready for lifting and processing then completed a bulk dig to over 5m in places. All materials had to be screened, which resulted in 85,000 m3 of arisings going through the screener,  plus around 12,000 – 15,000m3 of concrete went through the crushers.

The works included:

• Full obstruction removal and replacement of the materials to allow CMC piling to commence.

• Chemical testing to achieve the requirements under the material management plan. This was a requirement out as part of the planning consent.

• Relaying the ground back in place to perform ground bearing to check for suitability to become permanent work.

A large portion of the site was designated a medium risk UXO area, which had to be subject to careful excavation. The subsequent clearance to maximum bomb penetration depth meant the project was very challenging with a wide array of multi-layered activities undertaken at any one time.

Our original contract was digging to 2m, but a considerable quantity of large underground obstructions was below the 2m and removed to our works programme.

Downwell deployed up to 25 items of plant including excavators, screeners, crushers, rollers and dumpers working in tandem to achieve this project.

85,000 m3 of arisings going through the screener,  plus around 12,000 – 15,000m3 of concrete went through the crushers.
