Arsenal's Emirates football stadium north London, England was delivered ahead of time, under budget and without major disputes because it was simple to build, Sir Robert McAlpine's construction manager Andrew Veness said this week.
This is in contrast with Wembley Stadium which appears to have been over-complicated to the detriment of the project.
Work was fragmented at Wembley because of the roof construction sequence.
This involved building the iconic arch on the ground then raising it in stages using temporary structures in the pitch area (NCE 15 Jan 2004). This held up construction on the pitch and stands.
At Emirates, the tubular steel roof is made up of simple trusses which are bolted rather than welded together and without the complication of a moving roof.
And the Emirates' longest trusses were fabricated in two sections so that they would not encroach on terrace construction when assembled on the pitch (see cover feature, page 16). Good subcontractor relations early on and throughout the project ensured that the Emirates roof was easy to fabricate and erect, reducing the risk of delay on the project. Emirates Stadium was finished two weeks early and under budget, ready for the start of the new football season.
