Earlier this month we were awarded a contract to investigate the forecourt area at a motorway service area in southern England, for a major oil company, as part of a leasehold transition.
With data from over thirty boreholes and monitoring wells this was a relatively detailed investigation for forecourt investigation. However, our client understood that carrying our a comprehensive combined environmental and geotechnical ground investigation at an early stage invariable pays saves money in the long run.
We used our GeoProbe direct-push drilling system to construct boreholes, targeting key areas such as the below-ground fuel tanks, fuel lines and forecourt interceptor. We then analysed the soil and groundwater samples for our hydrocarbon suite at our own UKAS
accredited laboratory.
Our investigation report has provided our client with a detailed baseline study confirming ground quality and highlighting any areas of contamination at the time they took over mangement of the site.

Subadra Awarded Multi-site Remediation Portfolio
We have been awarded a major remediation portfolio by one of the UK’s biggest fuel retailers. The multi-site portfolio will see us working at a sites across the UK using a wide variety of both in situ and ex situ remediation techniques. We understand that a key reason for us winning this work was our ability to provide cost-effective turnkey solutions, integrating site investigation, laboratory testing, fate-transport modelling and remediation design and implimentation using solely in house resources.
Subadra Go Bananas
We certainly get to work at a wide variety of different sites, but a call from a major banana distributor was a first even for us. The underground pipework carrying fuel to supply their trucks had failed and required urgent replacement. At short notice we were on site replacing the corroded steel pipework with modern plastic equivalents. We sampled the soil around the failed pipework and our in-house laboratory was able to confirm within 24 hours that no significant ground contamination had occurred. Within 36 hours the fuel supply system was back in commission and the banana trucks had started rolling again.
Black Gold?
Sadly not in this case. But what do you do if you’re digging a hole and it fills with a horrible mixture of black fuel and water? Call Subadra of course! We are able to guide you with all aspects of contaminated ground from waste disposal or how to minimise the impact on your development programme to how to discharge your planning conditions.
The site in the photo is a filling station that is currently undergoing a full site redevelopment. When the contractor opened up the forecourt to remove the below ground fuel tanks the excavation filled with a heady mix of petrol and diesel that had accumulated over the years around the off-set fill points.
We were on-site within 2hours of being contacted. We collected water and soil samples from the excavation that were run through our in-house hydrocarbon laboratory. The results were issued within 48hours allowing the contractor to efficiently deal with the soil disposal and avoid costly delays to the works programme.
Subadra win multi-site forecourt investigation package
Subadra have recently been awarded a package of investigation works by one of the major oil companies. We were selected based upon our continued excellent working relationships with the end client and their project managers , continuing to provide a high quality service and as always being able to offer cost effective site investigation services.
Particular praise was made of the quality of our tender submission, highlighting key areas of excellence and capabilities which enabled the client to quickly and easily conclude that we were the service provider best suited to complete the works.
The works package includes investigating 12 retail filling sites using our GeoProbe direct-push drilling system. The majority of the chemical analysis will be completed by our UKAS accredited laboratory. The reporting deadlines for the package is six weeks from the point of instruction. Contact value: ~£55k+
There are always cost savings to be made when multi-site packages are being completed and we like to pass these savings onto the client. If you have a small network of filling station sites or are a ‘Top-50’ operator and need an environmental survey get in touch to discuss our highly competitive rates.
Foundations for Key City Data Centre
Whilst much of our work in carried out in the provinces we sometimes dabble with high finance in the City.
Subadra played a key role in the development of an £80 million multi-storey data centre facility in London’s docklands area. We were brought in at the inception of the project to carry out a geotechnical and environmental investigation to determine ground conditions.
Our investigation comprised a network of boreholes across the development area that were used to collect soil samples for analysis and groundwater and hazardous gas monitoring points.
The site was especially tricky geotechnically, comprising areas of in-filled docks, some highly contaminated and others containing very soft silts and clays.
We used the data to assist with foundation design and the classification of waste soil.
