The Challenge:

The scope of works included the identification, proving, clearance and diversion of existing utilities for what was originally estimated to be 400 conflicts. Due to the congested nature of the site in a historic city, over 1500 utility conflicts were identified and diverted.

The works were conducted in a high profile, complex, multi-utility, urban environment, with archaeological considerations across multiple sites. It required extensive communication with both public and businesses, along with significant pedestrian and traffic management.

Major diversions included a 315mm MP gas main in the centre of Princess Street and a 400mm strategic water main in South St Andrews Street.

The City of Edinburgh Council​​ were already working to a revised timetable and budget for the Trams Project, meaning we had to deliver to programme despite the changing requirements.

The Solution:

Our multi-disciplinary team began work on site within seven days from contract award. Our experienced management team ensured the project was kept at the forefront of innovation, within budget and with all milestones achieved.

This required close liaison in co-located offices with the Council, its project and cost managers, Turner and Townsend, and our designers, URS.

We demonstrated flexibility to respond to changing requirements when site issues arose at short notice. This lead to modifications of existing utilities and found clear routes for diverted assets.

Extensive Traffic Management planning and implementation was essential, to ensure access for the public to homes and businesses was maintained throughout.

Excellent relationships were forged with all the main utility companies, particularly Scottish Water, Scottish Power Networks and the Council's permissions team enabling us to jointly engage on complex stakeholder matters to expedite resolution.

The Impact:

  • Over 1500 utility conflicts identified and diverted, compared with the original estimate of 400, whilst delivering the project within budget and to timescales.
  • Carried out 400 remedial works on Scottish Water infrastructure and reconstructed six sewer manholes each 5m deep.
  • Saved both time and £60,000 by taking advantage of a digitally-based Contract Change Management (CCM) system for controlling design changes.
  • Maintained access for the public to homes and businesses at all times.
  • Minimised disruption to local businesses and residents by working 24 hours a day on critically important utilities on more than 40 occasions.
  • The success of this project directly led to us being awarded another contract to the value of £350,000.
  • The City of Edinburgh Council were subsequently awarded a Light Rail Award for bringing the tram project in on its revised timetable and budget.
" I very much recognise that the transformation and ultimate delivery of the Edinburgh Tram Project was down to the hard-work of all involved. "
