Supplementary Geotechnical Investigation

Residential Development – Houlton, Rugby

Following a detailed review of the site investigation report which our client was provided with, JPP recommended an additional supplementary geotechnical ground investigation in order to refine the development ground model with a view to providing cost savings on the project.

  JPP were appointed to undertake a supplementary geotechnical ground investigation to assist our in-house structural engineers on a prestigious residential project in Houlton. Our geotechnical design team specified and undertook a parcel-specific supplementary ground investigation using trial pitting techniques to allow the refinement of the proposed foundation solutions on a plot-by-plot basis.

Undertaking the supplementary ground investigation, geotechnical testing and detailed soil logging enabled our geotechnical team to provide the structural engineers with an increased allowable bearing capacity. The additional targeted geotechnical ground investigation, which was carried out on top of a standard site wide Phase II ground investigation, enabled JPP to reduce foundation depths across the site by 350mm based on the findings of the supplementary investigation. This reduction in foundation depths provided our client with a significant time and cost saving with respect to the earthworks and foundation phases of the development, by reducing the volume of foundation arisings produced and reducing the volume of concrete imported into site.

The reduction in exporting volumes of waste soils and reduced concrete volumes also plays a key role in managing and reducing the associated carbon footprint of residential developments enabling our clients to meet their environmental responsibilities.
