As part of the infrastructure works associated with the new Capital Square Development within Edinburgh City Centre, GCM were appointed to safely dismantle and remove the SKYPARK multi storey automated car park facility.  It was an essential requirement to ensure minimal disruption to surrounding properties and operational businesses within the busy environment throughout the execution of our works.

SKYPARK measured approximately  36m by 36m and peaked at 30m in height.  Although the superstructure was independent from The Edinburgh One building, when dismantled, left an exposed gable with no lateral resistance to wind loading or protection from water penetration.

With a split-level site, the Edinburgh One building gained its foundation support from SKYPARK. Our remit included the removal of all foundations and retaining walls.

We resourced and controlled this project from our Head Office in Banknock, deploying to site 

our inhouse specialist dismantling team.

GCM’s design was based on deconstruction, which ensured that that there was minimum disruption to the surrounding businesses throughout the project.

Our solution was to remove the structure envelope working from self-propelled mobile access platforms. 

A detailed temporary works design was developed and progressively installed to provide wind and weather protection to the adjacent party wall. 

A GCM inhouse survey identified the main structural components which allowed GCM to design a sequence of dismantling operations which retained the integrity of the structure during the dismantling process.

Using a self-erecting tower crane the superstructure was cut and lifted in modules to grade level where they were further processed using hydraulic cutting equipment.

Various temporary steelwork solutions were designed and installed by GCM specialist subcontractors to facilitate the removal of the foundations and interconnecting retaining walls.
