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.
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.
Contract value: £20-50k
Encountering obstructions during piling works and clearing these obstructions can cause significant cost implications and also impact upon the construction programme. However, delays and significant cost-overuns can be avoided by completing a quick and easy pile probing survey.
We recently carried out a pile probing exercise a high profile redevelopment project in central London. The principal contractor identified an old, below-ground fuel tank that needed to be removed. Due to adverse ground conditions and proximity to a basement and the adjacent road, sheet piling around the tank prior to its removal was considered the most effective and safest option.
We were brought in prior to the piling rig to identify an obstruction free boundary around the tank to allow the piling to be undertaken. We completed 400m+ of probing in two days using our Geoprobe drill rig, completing the works on budget and ahead of schedule.
Additionally, despite the working area having been surveyed and declared “service-free” by the principal contractor our drill team, who are all trained in service detection, identified a 4″ water main in our specified working area during our pre-enabling The findings from our probing allowed the pile design to be refined and the service clearance works we carried out avoided everyone from getting very wet.
Contract value: <£10k
