Brief description of the work:
Blackley Construction delivered the entire project including service location, traffic control, excavation, pipelaying, valves, hydrants and laterals installation, backfilling, testing, connections, cut-ins and all surface reinstatement.
The pipe ramming operation was a variation to the contract and once installed a 200mm pipe was inserted and fixed in position.
A comprehensive site specific health and safety plan was prepared for the site and this was integrated with our traffic management plan which did require special attention around the heavily trafficked roundabout. Site controls were put in place to ensure the safety of road-users, pedestrians and our own staff.
The site was reviewed for potential environmental issues but only our standard controls and procedures were required.
This project was completed on time and on budget with minimal disruption to the community.
All residents and businesses were notified of the work and supplied with contact numbers should they have any issues. The contract management teams from Blackley and MDC also met on a regular basis to discuss the project.
