ISG takes change in its stride at Horsforth, Leeds
ISG secured the contract to deliver a new headquarters for innovative healthcare technology company TPP in the form
of a four storey, steel-framed office building above a reinforced concrete box to house two under-croft levels of car-parking.
However, it could not foresee that the contract would generate hundreds of individual changes, requiring numerous time extension negotiations that would almost double the original length of the build, and grow the value of the project to more than £20 million before its completion in October 2015.
In September 2013, senior project manager for ISG’s UK Construction North business, Anthony Mitchell, found himself in charge of what would be a challenging 109-week development.
He set the scene: “The design of the building was complex: set on a sloping site the front of the building would have three storeys, dropping down a storey at the back.
The front elevation was to be clad in traditional Yorkshire stone, while the back would have a contemporary design with modern bi-fold doors
opening all the way along several terraces and balconies.
Its structure would require a combination of materials and bespoke items, from a major concrete-fill challenge to create the car park, to a
skeleton made up of custom delta beams, shipped from Slovakia.”
