Cleveland Bridge and a team featuring ZNS, the sister firm of Dutch company Hollandia, and Belgian contractor Victor Buyck return bids at the end of the month for the work, which is expected to cost around £30 million.
The package is being re-tendered but the original bidder, Belgian firm Iemants, has decided not to price the work this time around.
Mace has been asked by developer Teighmore, led by Irvine Sellar, to come up with a price that does not top £300 million for the shell and core of the job.
It is carrying out the tender process with the developer’s in-house project manager on the job, Primus, the firm set up last year by the former head of Multiplex’s UK construction arm Martin Tidd.
Tenders for the concrete package, whose bidders include Byrne Bros and John Doyle, are also expected back in the next few weeks. This will cost more than the steel job, coming in at around £40 million.
And Mace is planning to send out documents for the M&E parts of the scheme by the middle of next month. This is expected to cost around £60 million.
Fit-out work on the 310 m high tower will cost around £150 million and be completed for the Shard’s late 2011 opening. Keltbray has started work on the demolition contract, which is due to finish at the end of this year.
