ITALY WAS last week struggling to save the E4.6bn ($5.6bn) Messina suspension bridge project between the mainland and Sicily as NCEI went to press.
The project's governmentrun promoter was pinning its hopes on a second extension to the bid deadline after one of three short-listed consortia withdrew its bid.
The two remaining consortia have also lost key members and said they were considering submitting a joint bid.
The road/rail bridge incorporates a record breaking 3.3km central span, as well as extensive approach works including more than 30km of tunnel. The site also straddles two tectonic plates.
Austrian contracting giant Strabag said its consortium had withdrawn from the competition, complaining that risks were ill defined.
members included Bouygues of France, Spain's Dragados and Risalto of Italy.
Bid terms drawn up by government client body Stretto di Messina require the successful bidder to bear risks of:
unforeseen ground conditions,
land acquisition problems
materials cost increases
unforeseen maintenance problems The client is insisting on a fixed price 68-month construction programme.
'On a world record bridge these terms were not fair, ' Strabag head of civil engineering Martin Ullrich told NCEI.
He said the construction programme was 'very short.
Bids from the three prequalifi d contracting consortia were invited at the end of October last year and were to be submitted on 27 April.
Ullrich said there had been some hopes of negotiating new terms with the client.
But requests made in December for an extension of the tender period so that risks could be more fully explored were refused.
'We had 50 engineers working on the project. Even with 100 engineers, or 200, we needed more time to look at technical and financial issues, ' said Ullrich.
'It wasn't worth our while spending $12M to prepare a tender if we couldn't do it in time, ' said Ullrich.
Key members of the other two prequalifi d consortia, headed by Italian firms Astaldi and Impregilo, have also dropped out, citing similar concerns.
French giant Vinci, which last year completed Greece's landmark Rion-Antirion cable stay bridge, pulled out of Impregilo's line up earlier this year.
Impregilo is also believed to have lost Japanese steelwork specialist Ishikawajima Harima Heavy Industries.
Astaldi has lost Spanish construction giants Ferrovial and Necso from its consortium.
Impregilo now has an entirely Italian squad of Societa Italiana per Condotte d'Acqua, CMC di Ravenna, Sacyr, and Consorzio Stabile.
Astaldi is with Italians Pizzarotti, Co-operative Costruzioni, Grandi Lavori Fincosit, Vianni Lavori, Ghella, Maire Engineering and Japan's Nippon Steel.
With only two bidders left in the running, Stretto di Messina caved in at the eleventh hour to pressure from Astaldi for a tender time extension.
The bidding period was put back a month, to 25 May.
'This is a large, high risk contract. From a technical point of view it's very complex. We needed more time, ' said an Astaldi spokeswoman.
Astaldi and Impregilo said they had discussed whether to work up a joint proposal, and submit a single bid, added the spokeswoman. Neither contractor would confirm if this step had been taken.
