2004: EMCOR DRAKE & SCULL At £5.2 million, Emcor's subcontract for the mechanical and electrical services associated with the fit-out of BT's 12,000 sq m Sovereign Street office block in Leeds accounted for almost half of the total project cost. It was no picnic: Emcor had to deal with £1.2 million worth of client variations but it managed to accommodate the variations and deliver the project to programme and within the original budget.
2003: GEOFFREY OSBORNE Osborne's £1.7 million contract involved the sliding of a 4,500 tonne concrete box into position at the Shortlands Junction in south London using the Autoripage technique for which Osborne was the sole UK agent.The 80 m long, 13.5 m wide concrete box was pulled into position over a 27hour period while a fleet of 20 excavators worked in relays to shift 20,000 tonnes of earth out of its path. In a feat of meticulous planning and flawless engineering, a whole year's preparation came together in a single weekend possession.
2002: CANTILLON DEMOLITION Cantillon demonstrated consummate ability as both project manager and construction innovator on the £3 million contract to remove asbestos, strip out and demolish Standard Life's 11-storey office building at 2-12 Gresham Street.While archaeologists sifted away the earth in the basement, Cantillon worked off a scaffold structure cantilevered out at second-storey level, bringing the superstructure down using mini plant lifted into place with a tower crane.Massive time and cost savings were achieved as a result.
2001: CEMENTATION FOUNDATIONS SKANSKA Cementation's £7.8 million groundworks contract for a new seven-storey basement under Harrods and the neighbouring Knightsbridge Crown court remains one of the most complex geotechnical tasks ever undertaken in Europe.The job employed the latest compensation grouting technology and a sophisticated monitoring system allowed 35,000 pieces of data to be analysed quickly and efficiently each week with an in-house software package developed especially for this job.Cementation managed to shave 12 weeks off the original programme, saving £250,000 in the process.
2000: DRAKE & SCULL (joint winner) British Airways'Compass Centre forms the hub of BA's flight-crew and IT systems, controlling flights throughout the world.Drake & Scull's challenge was to design, manufacture and install a low voltage electrical supply to this critical operational building without once interrupting its 24-hours-a-day operations.The disruption that would have followed any loss of power was calculated at £10 million a day.
2000: KELSEY ROOFING INDUSTRIES (joint winner) Kelsey designed and installed the stunning Kal-Zip standing seam roof on the Millennium Stadium at Cardiff Arms Park.The £3.0 million contract brought with it severe logistical problems, largely due to lack of site space and poor site access.The original programme allowed 39 weeks on site, but careful value engineering enabled Kelsey to accelerate the programme to just 19 weeks - a feat the judges described as 'little short of heroic' 1999: CROWN HOUSE ENGINEERING Crown House's £16.2 million M&E contract for four new halls at the National Exhibition Centre, Birmingham, was an early demonstration of project partnering.Value engineering and off-site manufacturer were also extensively used, and efficiency levels of 98 per cent were achieved by increasing the amount of factory prefabrication.
