In 1960, Portsmouth Water was installing an 18? fibre reinforced concrete (FRC) water main from Fishbourne to Birdham to improve the water pressure in what was a rapidly growing area. It was during the excavation of a trench for this main, that the remains of Fishbourne Roman Palace, one of the most important archaeological sites ever discovered in Britain, were discovered.

The integrity of this FRC main has weakened recently, due to the corrosion of the steel couplings used to join the pipes, which has led to leaks.

Knights Brown was appointed to carry out the works involved with the replacement of the FRC main with 800m of 450mm diameter ductile iron water main, with associated bends, valves, fittings and thrust blocks relocated away from the main building and artefacts at the Fishbourne Roman Palace. Another section of pipe, which ran through nearby residential gardens was relocated to mitigate against damage and disruption that could potentially be caused to residents in the event of a future burst main in the area.

A section of pipe laying works in the highway was undertaken in short sections under single lane traffic controlled lights. Close liaison was maintained with residents, the primary school and Fishbourne Roman Palace throughout the contract, while maintaining access at all times.

Excavation work was closely monitored by archaeology specialist, who preserved, catalogued and reported the minor finds encountered.

our sectors

Knights Brown performed very well on this project in terms of quality, cost and time. The team worked very well as part of an integrated delivery team with the Employer to the benefit of the project

- Marc Bryan, Portsmouth City Council

Sites are always very well presented. First impressions count and if a site looks well organised and clean when you arrive then generally this is applied throughout the management of the projects. Indeed, all five projects I am Cummins PM for, have been managed to a high standard and equally the safety records and standards are very good.

- Iain Brooks, Cummins

Site staff were pleased to have had Knights Brown on the team, they were proactive from day one to the end towards potential issues and responsive to a changing site environment for works.
