In an historical part of Edinburgh the rehabilitation of a public space produced several engineering issues. Natural stone surfacing using recycled setts, slabbed event spaces and traditional asphalt construction were all present in the works.
Working closely with architects and the contractor we overcame many obstacles common with any urban environment, these include: utilities, basements, live traffic, shops and residents. All of these factors have a major impact on the works and each had to be considered individually to minimise disruption.
As the design evolved numerous surface and road base constructions were devised to maximise use of the area.
Additional problems arose from the abundance of archaeology in the site which included Victorian sewers, medieval foundations and many unknown artefacts.
The site incorporated several unique features including subsurface Christmas tree mounts, pop-up units from the ground supplying water and electrical power to markets and fairs. There was also numerous lighting and projection systems all requiring design and ducting routes.
