The project site is located within a former quarry – now disused and backfilled. This resulted in complex ground preparation prior to construction.

We assisted Hayfield Homes with the detailed remediation and dynamic compaction process, which resulted in NHBC approving an industry standard foundation solution.

The existing pumping station on site needed to be redesigned, which allowed a traditional sheet and frame temporary works system to be installed to depths of over 10m.

Complexities included running sand and a high water table; to overcome this we installed a full well-point dewatering system, which allowed safe access into the pumping station.

This was a challenging first development for Vistry Northern Home Counties in Cranfield, Bedfordshire.

As a solution for reducing both carbon exposure and project costs, we worked with Vistry’s commercial and technical departments to value engineer both subsoil and topsoil disposal quantities.

This value engineering was achieved by our in-house engineering department, who developed a detailed earthworks model, amending site levels to successfully accommodate the site’s total soil quantity.

This was then reviewed and perfected by Vistry’s own engineers and the final strategy resulted in huge value engineered savings for the project.

The site had restricted access with a large off-site haul road – temporary access was successfully installed through third-party land.

On-site water levels were under constant pressure – this was overcome by constructing temporary holding ponds.

The built-up residential area required careful management, with deliveries and plant access carefully planned to reduce the disruption for residents and the local school.

Within 12 months of commencement, 90 new homes were completed, along with the adoptable infrastructures both on and off-site.

This was a hugely complex project within Wellingborough’s largest strategic development.

Ground conditions and level differences on site meant a detailed earthworks operation was necessary, achieved concurrently with the installation of infrastructure.

Permanent retaining solutions were constructed in advance of the groundworks, foundations and substructure works to resolve this issue.

With the latest 3D machine control technology available, the in-house MIDA engineering department designed a bespoke earthworks model.

This allowed the site to progress permanent works, ensuring the delivery programme maintained the planned schedule.

This was the first development in decades in the existing village of Stilton. This meant that it was vital the initial phase of construction was sympathetic to the local residents and environment, and ensured compliance with the local authorities construction management plan.

As well as managing the construction project in a way which avoided disrupting local residents, we redesigned service routes to limit and mitigate the level of temporary works required to provide access/egress to the construction site.

This was achieved by careful and considered project planning in partnership with Bellway’s own engineers, and relevant utility providers.

Limiting temporary works and progressing to the permanent works solution reduced potential disruption locally, and saw construction run efficiently.

To meet an accelerated client build programme, we increased resource for this construction project, pulling delivery dates forward. We aim to have the front-end groundworks for this development completed within a seven-month period.
