Delta-Simons has provided environmental support services for Stirlin Developments’ Leafbridge commercial development site in Lincoln.
As a former sand and gravel extraction pit infilled with spent foundry sand, the condition of the 44-acre site’s ground was unknown but likely variable. Distinguishing between the spent foundry sand and any natural geology was crucial for making foundation recommendations for the development and designing the site’s drainage strategy. Delta-Simons supported the project’s planning application through to the final verification stage, providing geotechnical and environmental investigations as well as ecology assessments across the site.
A number of investigations were undertaken prior to the site levels being remodelled, although plot-by-plot investigations were also required to confirm the geotechnical and environmental conditions of the underlying soils.
Most recently, the firm undertook site investigation for four plots across the sites. Twelve boreholes were advanced beneath each plot with the associated soil logging and sampling also conducted. These investigations helped provide a comprehensive interpretation of Leafbridge’s geotechnical ground conditions and informed the design of suitable foundations.
Delta-Simons’ previous work on the site included: preliminary risk assessments, site investigation, ecology desktop assessments, bat surveys, lizard translocation surveys and Japanese Knotweed treatment supervision. All these services were required to prepare the site for design and construction of the offices and commercial units.
Once complete the development will offer employment space to a large range of businesses.
