Omnia Environmental Consulting (OEC) were commissioned to undertake an intrusive ground investigation of a former metal plating works and former rotational moulding warehouse in Brighton. The site and the surrounding area has a long industrial history since the early 1900s.


Ground investigation works were undertaken over three phases, and identified limited chemical concentrations within shallow soils and deep groundwater beneath the site. This led to a requirement for a Controlled Waters Risk Assessment and a Piling Risk Assessment, which were both successful in demonstrating that the development works did not present a significant risk to Controlled Waters.

The initial phase of ground investigation works were undertaken  pre-demolition, with additional phases completed during the construction phase, where it was necessary to build a close relationship with site to allow intrusive investigation to take place while not delaying site activity. A extremely challenging phase of the project was the advancement of a borehole with limited space, bordering a neighbouring site.

This was overcome by pre-planning access routes, informing stakeholders of works and making sure the work environment was safe before proceeding. This allowed for the works to be completed safely and efficiently meeting the Clients timeframes.
