Confidential Client Civil and Structural Design and Inspection Services

FT have carried out a number of projects at this facility to ensure compliance with the company’s IPPC licence;

• 7-day Hydrostatic testing of concrete bunds and 24-hr hydrostatic testing of mobile metal and plastic bunds in accordance with the BS 8007 “Design of concrete structures for retaining aqueous liquids”. This testing is required by the EPA every 3 years and all the bunds at this facility are divided into 3 groups of bunds with 1 group requiring testing every year. FT produced testing certificates and a report outlining the test procedure and the results.
• Bund capacity review of all bunds on site to ensure that the volumes of tanks stored in the bunds are in accordance with EPA regulations.
• Calculation of the depths at which rainwater should be emptied from each external bund to avoid overtopping of the bunds should a tank failure occur.
• Decommissioning plan for an underground tank following the diversion of services from an unused section of the site.
• Carried out inspections and created a repair strategy report for several damaged concrete bunds.
• Visual inspection and certification of surface water lagoon.
• Advise on the installation of automatic pumps at sumps and the construction of new access chambers to allow access for the weekly inspections.
• Visual condition report based on a drone survey, of concrete tanks. The drone survey was required as the tanks are a confined space and no entry was allowed. This drone survey was carried out under FT supervision and direction.
• Final effluent line inspection and condition report
• Oil interceptor condition surveys and design of a new double oil interceptor on the storm water line
