More unforeseen ground claims likely on Boston Central Artery

MORE CLAIMS due to unforeseen ground conditions are threatening to further increase spending on the Boston Central Artery project.

Independent adjudicators have already ordered the client, the Massachusetts Turnpike Authority (MTA), to pay the joint venture contractor building the £253M Fort Point tunnel £20M for 236 days lost due to unforeseen ground.

The joint venture of Perini Corporation, Kiewit and Jay Cashman claimed it had lost 434 days at a cost of £35M.

MTA claimed no days had been lost.

MTA now faces two further claims, worth £65M, from the joint venture, which are understood to cover extra materials and equipment needed to tackle the unforeseen ground.

The project, considered one of America's most important construction schemes, had been back on track earlier this year (Ground Engineering February 2001), after slipping programmes and soaring costs saw the original price rise from £7.34bn in February 2000 to a revised price of £9.57bn.

MTA has headed off other claims from contractors by agreeing a settlement in return for a written promise that no further claims will be made.
