Eurocentral Business Park

RJ Utility Services Ltd were awarded a one off contract to fabricate, weld, install, pressure test and chlorinate a new PE water infrastructure network within a business park development outside of Glasgow.

The contract was awarded after a competitive tendering exercise, carried out by the client, identified RJ Utility Services Ltd as the most cost effective and suitably qualified tenderer. Work on the contract commenced in June 2008 and was completed within 200 “person days” ahead of the clients required completion date in June 2009.

The infrastructure network involved 3km Mains Cold Water and Fire Hydrant main, ranging up to 355mm in diameter including associated valves and fire hydrants, as well as other smaller services to building and water features. As this project fell under the requirements of CDM RJ Utility Services Ltd fell under the remit of the principle contractors F10 requirements and associated construction phase planning arrangements.

One of the challenges on the contract was the requirement for our teams to fabricate, install and manoeuvre large diameter pipes within restricted work spaces on a development site which required working around other trades, moving plant and site operatives. Our risk assessments and work methods had to take these factors into consideration when working on this site to ensure our work was completed to programme and with the safety of all site personnel paramount.

Another challenge the company had to overcome was the lack of consistent access to site and sustained periods off site of up to one month. Again, our methods and risk assessments with regard to pipework integrity and hygiene had to consider with and address these factors.

The subsequent pressure testing and chlorination of the installed pipework had to be carried out to meet the Scottish Water specification and standard as opposed to the Northumbrian Water standards we are used to operating to. This required additional training of our employees which had to be sourced, organised, and undertaken before work commenced on site.

The pressure test consisted of a 12 hour test to 10bar with subsequent swabbing, chlorination, sampling and flushing.

The installation programme was devised and managed in conjunction with both client and RJ Utility Services Ltd personnel to ensure that the programme was achievable and the required timescales and milestones were met.
