Pochin Construction site survey – Wigan
Pochin Construction was in final negotiations to construct an 110,000 sq ft speculative warehouse on the outskirts of Wigan. The site development was to comprise of a large car parking area, loading bays, dock levellers and an extensive concrete wagon park and turning circle.
The LK Group was invited to carry out an initial survey to determine the extent of the Japanese Knotweed. We found the site to be moderately contaminated however, the strands of Japanese Knotweed were just outside the main areas of concern and a number of disposal and/or on-site treatment methods would be suitable for this site.

Outcome
THE SOLUTION
Following volumetric calculations on the proposed green space, we developed a strategy to retain all material on-site, while clearing all infestations form the construction zones, allowing works to progress after just two days.
THE BENEFIT
All Japanese Knotweed material was retained on-site with the use of root barrier membranes. This resulted in a large saving on both programme and cost.
