New Sheltered Housing at Ivanhoe Court, Bolton

Architect – Pozzoni

Civil & Structural Engineer – Carley Daines & Partners

Contractor – Richardson Projects

This project involved a relatively small site, containing 20 new housing and bungalow units.

The site was constructed on former railway sidings, and extensive initial investigations were undertaken for potential contaminants.

However, the greatest challenge was provided by a restriction on the amount of storm water flow that could be permitted to enter the existing adjacent public sewer system.

A scheme was therefore designed using the latest computer drainage modelling to incorporate a large galvanised steel holding tank on site to contain storm water run-off and then permit its dissipation into the drainage system at a manageable flow.

This scheme involved careful collaboration with Bolton MBC and United Utilities (the drainage authority) as the existing drainage system within the area was considered to be under capacity and extremely prone to surcharge and flooding.
