Client: Morgan Sindall
Project start: October 2012
Project finish: January 2013
Location: Pudding Mill Lane, London
J Browne installed 100m of PE225 barrier pipe for a water service diversion at two locations Marsh Gate Lane (60m) and Barber’s Road (approximately 40m). Both locations are within the new Pudding Mill Lane Station Development.
This service diversion was critical for the Tunnel boring machine (TBM) as it needs a water supply.
There were constraints on the site namely heavily congested with other contractors working in the same vicinity, working within deep excavations and working near HV cables (which supply Liverpool Street Station) We managed the various interaction of all the communication and TV companies providing data at the Venue.
The main difficulty faced during the course of this project was the discovery of a high incidence of unchartered services in the path of the new surface and foul water routes and we also discovered an unchartered water main which we dug around and raised to install our pipework underneath.
The works were completed on time and without any safety incidents.
J Browne successfully completed the works on programme meeting key dates (February 2013) working in close collaboration with Morgan Sindall, Crossrail and Thames Water.
We have since returned to the site to carry out additional works which included:
Trial trenching works: 3No. 12m x 1m x 0.9m holes to locate the placement of existing services on site.
Installation of a flow meter and chamber at Marsh Gate Lane.
40m of trench digging for installation of HV cables which was completed over one weekend working 12 hour shifts, accompanied by a HV Competent person.
“We have used Browne’s for a few packages of work now at PML and have always been pleased with their performance across the board. They are particularly helpful with upfront value engineering, have a competent site team and maintain a good working relationship with Thames Water. They are currently taking on and pricing further work packages for the project."
