Northpoint completed a Phase 1 Desk Study Report and Phase 2 Intrusive Site Investigation for a proposed residential development in Heaton, Newcastle-upon-Tyne.

Land within the grounds of the existing social club is being considered for detached housing. Northpoint’s desk study considered all potential geo-hazards associated with the ground. The assessment considered the sites history dating back to the mid 1800’s through to the present. Northpoint considered a range of data sources, such as Environment Agency mapping and data, to Coal Authority mining information.  The Desk Study, also considers the preliminary flooding risks to the site (from rivers, groundwater and surface water).

A preliminary Conceptual Site Model and Risk Assessment was completed, and from this process, Northpoint designed and carried out targeted Phase 2 Intrusive site investigation works.

The investigation phase was deemed necessary to establish the presence of potentially unacceptable risks to both construction workers and residential end-users from contaminated soils.

The intrusive site investigation included a soils survey. The survey included excavating a series of trial pits, particularly in areas of proposed soft landscaping.

Soil sampling and laboratory analysis was undertaken to assess whether the site had been impacted by land contamination sources, including heavy metals and asbestos presence.

The soil survey data was used to update the initial desk study phase Conceptual Site Model and Risk Assessment. This information was submitted to the Local Authority in support of the granted planning consent.
