Demolition makes way for new Cosham Fire Station

HWM Group were delighted to be awarded the contract providing demolition, remediation and civil engineering services on the Morgan Sindall Group Plc project for the new state-of-the-art Cosham Fire Station in Portsmouth.

Work is being completed in three stages starting with demolition of the former Portsmouth Craft & Manufacturing Industries site. The cut and fill then followed ensuring the contaminated made ground was delineated and disposed of off site. Levels were then made up across the site utilising 6F2 and type 1, both of which were made on site using demolition arisings. Groundworks then swiftly followed with forming pads and underslab drainage to allow the steel frame to commence.

The new Cosham Fire Station is designed to include improved training facilities, separate zones for managing clean and dirty contamination, plus space for training and services partners.

HWM Group Demolition works were completed with the recovery and removal of all recyclable materials by our own waste management division. Concrete and masonry materials were recycled, crushed on site and re-used as part of the groundworks, reducing road movements and the need to bring aggregate to the site.

HWM Contracting completed installation of the attenuation tanks and all underground drainage. The groundworks started in the area of the main block of the new fire station with the excavation of materials creating the required site levels.  Foundations were completed in May ready for Morgan Sindall’s steel frame contractor to start work. With slab prep now following including the installation of a very detailed waterproofing system.

HWM Group Director Chris Lynch said “This project is the perfect example, personifying the service that HWM Group can provide. We have carried out the demolition, remediation, earthworks and groundworks. The ability to carry out multiple phases of the work concurrently means we are able to significantly better most contract programmes, advantages of which, everyone benefits from”.


The new Fire Station is due to be commissioned with crews moving to the site in summer 2024.
