Resolving contamination risk at Phase 1 using existing ground data

London
Phase 1 Environmental Assessment

Location
London
Sector
Residential
Contamination risk was closed out without a new site investigation.
Cleared at desk study
No remediation was required for the new homes.
No clean-up needed
01

The uncertainty

The project team needed to know whether the proposed residential redevelopment introduced a material contaminated land risk, and whether further intrusive investigation would be needed before the scheme progressed.

02

What we established

Previous third-party ground investigation data, reviewed alongside the site history and setting, was sufficient to assess the risk. No further contaminated land work or remediation was required for the proposed residential use.

03

What changed

The project team had a proportionate planning route based on the actual site risk, with geotechnical design requirements addressed separately.

04

What was avoided

An additional contamination-focused Phase 2 investigation, and any remediation.
05

How we got there

  • Phase 1 desk study reviewing site history, environmental setting and planning information
  • Site walkover
  • Review of previous third-party ground investigation data
  • Preliminary conceptual site model for the proposed residential use
