Practical completion at 100 Liverpool Street, London

Great milestone achieved as British Land award Sir Robert McAlpine Practical Completion of 100 Liverpool Street.

We are pleased to announce our joint client, British Land and GIC have granted practical completion of 100 Liverpool Street, London.

100 Liverpool Street is the flagship project in the Broadgate Campus development pipeline for British Land and GIC which is being delivered using a 10 year Framework with Sir Robert McAlpine, to transform the Broadgate Campus into a world class, 7 day, mixed used Central London destination.

100 Liverpool Street is a large complex project that has involved stripping the building right back to its original structure and in the process demolishing 50% of the building. Much of the demolition took place above a live shopping mall which remained open throughout the construction of the new building. The new structure created 520,000 sq ft of retail and office space with retail on the ground and first floors and a new restaurant on the ninth floor boasting panoramic views across to St Paul's - one of the largest open-air restaurant spaces in the City of London.

The project was a shell and core construction with the main reception and toilets fitted out and presently the tenants are fitting out their areas in anticipation of imminent occupation. An example of the complexity of the project was the lowering of the Fulcrum sculpture, a 200 tonne piece of cor-ten steel artwork located in the shopping mall which was lowered in situ by 1.4m using hydraulic jacks whilst the mall remained open to the public throughout this challenging engineering process.

At the heart of the commercial offices within 100 Liverpool Street is a spectacular elliptical glass atrium which has a dramatic feature staircase within it, serving the upper office floors. In the original design, this staircase was to be hung by just two rods from the roof, 8 storeys above although Sir Robert McAlpine saved £1m for our client by redesigning it more conventionally, so that it spans from floor to floor without affecting its appearance or detracting from the splendour that is the main office reception atrium, which is a true masterpiece and a jewel in the crown of the new office development at 100 Liverpool Street, London.
