Project Brief

This project delivered 20 dwellings, comprising one two-storey, and two three-storey residential blocks, for Knowsley Housing Trust. Its success was due to an integrated approach within the project team.


The constrained site at Pinnington Place was originally a railway siding, and was bounded by an operational railway line, road and a car park. It also had a live sewer running through it, as well as being contaminated by hogweed. The site was also close to a conservation zone, so close liaison with the local planning department was key to the success of the scheme.

The scheme was delivered on time and within budget, working with the support of HCA and Knowsley Council.


We were able to influence the foundation design by working with surveyors to plot the course of the sewer through the site, which enabled the piling contractor to commence work and keep the project on programme. We advised CFA piles, to minimise vibration during construction, whilst ensuring global stability of the buildings.

We worked closely with the architect to develop the optimum placement of the buildings on the site, by advising and commenting on plans. Safe placement was of upmost importance, to avoid disturbing the live sewer during piling activities, and to accommodate the 3m easement around it. We also advised on scaffolding positioning to accommodate the operational railway line, ensuring a safe area of work, which met CDM regulations.

We worked with planners to agree an upgrade to the access road serving the site, which was economically viable, to the satisfaction of the conservation officer and appeased the local residents
