GeoCon undertake a batch of Phase I preliminary site investigations at a number of schools across the Bolton area for a large consultancy. All of the schools were constructed prior to any contaminated land legislation and have been built in areas of former industry, mineral extraction and land filling. In addition, due to the presence of coal mining across the area the majority of the sites ware also at risk of settlement due to shallow coal mining.

All sites required further assessment by way of Phase II site investigation including trial pitting and window sampling to investigate the nature and extent of any contamination at the sites, and on some site rotary open hole drilling to investigate the presence of shallow mine workings and rotary probe hole drilling to investigate for the presence of untreated mine shafts.

Our client was delighted as we helped them through a back log of work and delivered before the deadline.
