Innovation and teamwork deliver success at Millharbour

摘要

Groundforce has cemented its relationship with specialist contractor O'Keefe with the completion of the team's second challenging basement project in east London. 45 Millharbour is a 14-storey mixed-use development located in the centre of the Isle of Dogs, within an area designated by Tower Hamlets Borough Council as the "Millennium Quarter". The project, which is being managed by F3 Construct for developer Facilitas, got underway late last year, with basement excavation beginning in April 2015. Groundforce secured the £90,000 contract to provide support for the 90m long, 26 - 32m wide excavation against stiff competition, says Ajay Nagah, Senior Engineer (Major Projects) with Groundforce. The 8m-deep excavation was 32m wide for most of its length, with a narrower, 26m wide, 24m long section at one end. The 32m unsupported span required the use of Groundforce's 250 tonne capacity MP250 modular hydraulic props with 1,220mm diameter "super-tube" extensions to achieve the stiffness needed. The 150kN/m loads, coupled with the 8m prop centres and 32m span, necessitated the use of large props and tubes, In total, eight MP250 units were installed as cross struts, with two of them supporting the 26m wide section.
