The site is a former oil refinery and the same stringent fire precautions remain in place, this necessitated the use of flame and heat resistant overalls in addition to the usual ppe.
The purpose of this testing is to provide information for decision making in relation to retention or removal of excavation arising or any other spoil from site. We supervised and monitored a total of six trail pits mechanically excavated across the site. Trial pits were taken down to a depth of up to 1.50m.
A total of twelve near surface samples were collected from several locations across the site at depths of up to 1.50m. The soil was monitored on site with a photo-ionisation detector (PID) to identify any elevated levels of volatile compounds and assist in sample selection.

If your project site covers a large area you will need an aerial view. We can provide this view using our survey drone.
Below is a video of a large site (9.13 ha) using our survey drone. This video was used in the desktop study to assess the entire site, taking the pictures and films our client needed.
Being a future-facing company we choose to invest in new technologies enabling us to provide you with the best quality services.

Greystones, Truro, Cornwall
The proposed development site is located on the side of the valley adjacent to a shaft and engine house for a former copper mine that worked between 1817 and 1874 producing almost 25,000 tons of copper ore. This site has also been used as a telephone exchange and radio hut during the war as well as a private workshop and printers.
It was an interesting challenge to attempt to offer pragmatic cost effective options for safe development for residential use. With risk of contamination and possibility of ground instability the structural integrity of the mine shaft, the surrounding wall and the nearby chimney all to be considered it certainly makes for an interesting project.
