Project Summary

Project Value: £9.5m
Project Duration: May 2024 - Jan 2026. 22 months.
Expected Budget Saved: £3.1m

Econ Group were successful in securing the project during early 2024. The scheme spanned over 8 weeks and included the treating, segregating, and disposing of over 6000m3 of contaminated soils. The contaminants included asbestos insulation and insulation board, oils and hydrocarbons.

Our work involved the removal of asbestos contaminated soils from various locations throughout the site, this was carried out via an excavator loading self-sealing tippers.  Works were carried out under a watching brief from our in-house licensed asbestos removal team, which consisted of an asbestos supervisor and asbestos removal operatives. Upon completion of the excavation for the base and sides, the area was then covered with high visibility geotextile terram and backfilled to the client’s design specification with stone.

A project specific AMP (asbestos management plan) was produced summarising the requirements detailed blow.

1)       A summary of known asbestos issues at the site and asbestos type assessment.

2)       A description/ detail of the excavation work and final install.

3)       A discussion in relation to CAR 2012 compliance.

4)       Current risk level, asbestos licensing/notification requirements.

5)       An asbestos protocol/Plan of Work detailing actions required in terms of different asbestos types encountered.

6)       Waste classification summary.

7)       A CAR 2012 risk assessment.

Being a licensed asbestos removal contractor, and soil remediation specialists our AMP document partnered with the licensed POW and ASB5 notification to the HSE.

The above paired with our mobile treatment permits SR2008 NO 27 and SR2010 NO12 provided a number of different remediation and treatment options, for both on site and off site offering a huge potential to recycle and reclaim useful products from the waste/contaminated material.
