Clydebank Re-built is an organisation dedicated to regenerating Clydebank. The Hospital Gate project is one of many in this continuing development. The main element of the works entailed developing a 14 hectare site at the riverside for office premises and associated businesses, together with a new access road.

Activities

  • Contaminated land remediation, infrastructure development and soft landscaping
  • The enabling works involved raising the ground level as part of flood prevention measures
  • An existing stockpile of some contaminated soil mixed with concrete, brick and metal was identified as potential material. This stockpiled waste had been historically excavated from various locations in the surrounding area. Contamination consisted of hydrocarbons of various natures and configurations – and varying degrees of weathering – with concentrations ranging from 2,000mg/kg to around 7,000mg/kg
  • Treatment of the contaminated soil was required to lower the chemical contamination concentrations to an acceptable level, so that waste could be classified as non-hazardous prior to its use in the development. The material was physically screened and crushed in-situ, which eliminated the need to import around 1,000 tons of alternative material
  • The progress of the bioremediation was tracked using on-site rapid chemical analysis, via a Site Lab Field Hydrocarbon UV Fluorescence Testing facility. All material was successfully remediated to below the Site Specific Target Level of 1,000mg/kg Total Petroleum Hydrocarbons. This allowed the material to be re-used on site in the construction of the development platform.

Outcome

The land is now being redeveloped to provide an improved access road to the Golden Jubilee Hospital and to the industrial units in the vicinity, as well as the formation of development platforms for future retail investment. We will also be constructing a walkway along the riverside.
