Project overview
Provectus supported the transformation of a former gasworks and railway sidings site into a new residential-led development. With a legacy of hydrocarbons, asbestos, and heavy metals, plus proximity to sensitive Network Rail and London Underground assets, the project demanded a highly controlled remediation and enabling works package.
Key Challenges
- Hydrocarbon, metals, and asbestos contamination.
- High risk of unexploded ordnance (UXO) due to historic railway sidings.
- Live constraints working alongside Network Rail and LUL assets, including high voltage cabling.
- Temporary works designs required adjacent to Jubilee Line and C2C viaduct.

Our approach
- Developed a Materials Management Plan to maximise reuse of site-won soils.
- Excavated and levelled 56,000 m³ of soils, re-engineered 32,000 m³, and disposed of 9,500 m³ safely off-site.
- Installed 21,000 m² of 6F2 piling mats for foundation works and pedestrian bridges.
- Completed UXO clearance using a rig-mounted magnetometer under specialist watching brief.
- Delivered Category 2 and 3 temporary works designs to protect adjacent rail infrastructure.
- Worked under HV supervision to safely excavate around Network Rail’s assets.
