PAS128 Utility Survey of The Grafton Centre, Cambridge


Providing up to date survey information to support proposed plans to redevelop The Grafton Shopping Centre in Cambridge, Terrain Surveys were pleased to undertake this PAS 128 utility survey. The Grafton, which was opened by the late Queen Elizabeth II in 1984, is one of the three main shopping centres in Cambridge, sitting just to the east of the city centre. Working for our client, 2110 Consult, this utility survey would take place over the course of 3 weeks. Along with the utility survey, we were also tasked with undertaking a topographical survey of a smaller area within the site.

The Challenge 

The Grafton was to remain open and operational throughout this utility survey, and we were tasked with surveying all pedestrianised areas, public footpaths and car parks on site. Working within high footfall areas brings unique challenges, and it was therefore essential that our utility survey team strictly adhered to our working practices, which seek to mitigate disruption to the public and business operations. With decades of experience within the leisure and retail sector, Terrain Surveys were well placed to ensure the survey was successfully delivered. 

The Results 

Strictly adhering to PAS 128 standard, our utility survey team used both Electromagnetic Locating Equipment (EML) and Ground Penetrating Radar (GPR) techniques in order to map all utility services within the site. The topographical survey, which was undertaken with a total station, captured site elements ranging from building and kerb lines, street furniture, service covers and levels. 

After 3 weeks on site, the utility survey and topographical survey data were processed and collated with utility records, to produce one comprehensive survey drawing in AutoCAD format. Once quality checked, the survey was delivered to the client within the agreed project timescales.
