Ground Investigation of a Complex Development – Brighton

Omnia 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 and the proposed development had residential end use.

Scope of Works:

Ground investigation works were undertaken over three phases, which identified limited chemical concentrations within both shallow soils and deep groundwater beneath the site. This led to a requirement for a Controlled Waters Risk Assessment and a Piling Risk Assessment.

The initial phase of ground investigation works were undertaken pre-demolition. During this phase, it was necessary to build a close relationship with site tenants to allow intrusive investigation to progress whilst not impeding daily operations. An 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.


Omnia are pleased to see that the development was completed in 2019 and features 59 residential flats and 6 terraced houses. It is great to see the scheme built out, creating modern new homes in lovely seaside locations.
