WORK has started on the latest phase of refurbishment at a decommissioned chemical works.

Building work has been ongoing at the Elementis Chromium site in Eaglescliffe, near Stockton, since the chemical plant ceased production in 2009.

Midlands-based engineering and management consultancy Design2e has been commissioned as designer and project manager for the site’s Residue Disposal Facilities since 2012.

The contract includes the production of detailed earthworks, cell cap design and specification, drainage and overland flow modelling, geotechnical testing, the production of a construction quality plan and overall validation.

Chemical cells containing chromium were buried at a depth of 20 metres at the site.

Wayne Holt, the company's executive director, said: “Every year we produce a design for the area to be refurbished. This is now our fourth tranche of work at this site.

“Working within legislative specification guidance, we have worked to strengthen the clay walls, as well as strengthening and improving the surface layer.

“We have also modelled the profile of the area to ensure that rain runs off and is managed effectively.

“This will be an ongoing process to ensure the residue disposal facility is maintained and managed effectively for years to come.”

As project manager and designer, Design2e, which has recently relocated to central Birmingham, works closely with the client and undertakes a thorough procurement process and always commissions contractors from the region where possible.
