Victorian Drain Replacement

Following on from our successful refurbishment of Burnt Oak School’s Victorian doors and frames, Price Building Consultancy were invited to tender for another renovation project with the school. As with all public sector contracts, we still needed to go through a pitch process, where we went on to win against three competitive companies.

The project, again, involved the replacement and upgrade of legacy Victorian building works – this time for the school’s underground foul, drainage and rainwater systems. The old Victorian china pipes and drains were majorly damaged and many had collapsed. They also ran 9 metres deep and over 100 metres long under the school and grounds. This meant we were required to create numerous intermediate shafts between man-holes across the playing field, and diamond cut sections of the playground.

The project required up to 16 different expert staff on-site, with the rental of specialist machinery including 7.5 tonne Volvo Deep Excavation Diggers and 3 tonne Dumper Trucks. Due to the depth of the ground work, safety was imperative; everyone had to wear specialist equipment and uniforms at all times and a process of shoring up the sides of all ground entrances provided stability to the drainage areas whilst we worked.

Ensuring Quality

Following the installation of the new OSMA pipes, which are of the highest quality, we needed to ensure all the drains were clear. We used CCTV cameras to check the entire new drain system and any that were found defective were high-pressure jetted and re-lined. Once all of the drains had been quality assured we backfilled the majority of the soil, and took the rest away as segregated waste. We repainted the playground lines and all of the sports pitches, re-turfed the grass and re-tarmacked the areas of the playground which had been disrupted during the project. Everything was completed over the six-week summer holidays, on time and budget.
