The solution

Despite projected costs for the overall scheme spiralling to over £1 billion, our “flexible and positive” approach was commended by the client in the construction of various structures, and trackwork, starting from Haymarket Station and finishing at Murrayfield Stadium.

The £23.3 million project required the construction of six structures, inclusive of bridges, underpasses and viaducts, two tram stops and 1200m of tram track. Elements of the works, necessitating close liaison with Network Rail, included drainage and reinforced concrete structures and temporary works consisting of sheet piling and soil nailing.

We identified £1 million of savings by advocating a Soil Mix Column Design through a contaminated area as opposed to the relevant stakeholder’s Dig and Replace method.

Innovatively, we also reduced disruptive and local possessions by pushing for Centre Overhead Line Equipment (OHLEs) rather than offset and employed only three rail possessions through effective planning and the implementation of ‘Rules of the Route’.
