Former RAF Airfield - Tangmere, Chichester

Client:Miller Homes (Southern)
Date: 2015-2016
Nature of works: Soil & Groundwater Remediation & Development Platform Preparation
Contract Value: £950K

Soilfix were contracted to carry out breakout, soil remediation and development platform preparation works at the former RAF Tangmere Airfield.

The Challenge
A 4Ha portion of RAF Tangmere has been redeveloped to a 125 unit residential housing scheme with private gardens.  Site investigations identified sub-surface macadam containing coal-tar bitumen, which presented a risk to the underlying Principal Aquifer from polycyclic aromatic hydrocarbons (PAHs).  The site also contained significant in-ground structures and asbestos containing materials including cement fragments, insulation board and lagged pipework below the site.

Our Solution
Soilfix implemented a sustainable and cost effective solution in conjunction with idom Merebrook, all in accordance with a Materials Management Plan (MMP) developed in accordance with CL:AIRE Code of Practice (CoP), including:

  • Stabilisation/solidification (S/S) treatment of 4,100m3 coal-tar bitumen contaminated soils to reduce PAH leachability to below stringent leachate criteria;
  • Additional S/S treatment of unforeseen areas of aviation fuel contamination;
  • Targeted removal of asbestos lagged pipework as licensable works;
  • Comprehensive breakout of slabs & sub-structures, processing majority to Type-3 specification for permeable paving below development roadways & external areas;
  • Hand-picking of asbestos cement debris from made ground soils;
  • Cut / fill reprofiling site to development platform levels, incl. lime stabilisation to achieve optimal moisture content; and,
  • Construction of working platforms for vibro-piling operations.

In spite of numerous unforeseen encountered during the project, Soilfix completed all works in sufficient time to allow unimpeded progress of Miller’s construction programme.  Of the total 20,000m3 materials subjected to processing, only 785m3 of unsuitable material required disposal off-site, resulting in almost 95% materials recovery achieved.
