reduction of the cost of Pier #5 to $1,-866.21 which is allowed.
The grand total of the Contractor’s claim for extra work on the eight piers is $117,387.63. Defendant’s engineer would cut this amount to $58,916.82.
I have allowed for the extra work on the eight piers $91,230.43. This sum includes $9,190.23 compensation and liability insurance and $2,746.40 social security and unemployment insurance both of which the defendant claims should be excluded as not coming within the terms of the contract.
The second item in plaintiff’s specifications is a claim for “extra cost of and placing additional concrete in caissons as required to sink caissons at the site.” $2414.
Defendant’s engineer admits that the amounts and the prices, the unit prices charged, are substantially correct, no dispute, but he says in a letter of May 18, 1940, that “the claim is without basis of reason or without justification according to any provision of the contract.” Notwithstanding this, I am going to allow the item as extra expense in the sum of $2,-414.
Item 3 of the specifications is for extra cost of operations due to undisclosed and undiscoverable proximity of the new structure to the old bridge, totalling $17,016.50 of which claim is made for an additional cost of 50% of the above which is $8,508.-25. This is based on the theory that at least fifty per cent of the total cost was due to the unusual proximity of the new structure to the old.
This item is distinct from the cost of extra excavation allowed for Pier #17 under the first item of plaintiff’s specifications. The total figure of $17,016.50 is the general expense of floating the caissons into place, anchoring and sinking the same. The plaintiff claims that this expense was largely increased by reason of the proximity of the new structure to the old railroad bridge and that the same was a delicate and difficult job requiring the hiring of extra tugs from Boston. It is the plaintiff’s estimate that one half of the cost should be allowed because the extra cost could not be determined when the bid was made as the proper data for such determination was not shown on the bidding plan.
I cannot say that the plaintiff’s estimate is unreasonable, based as it is, upon actual figures, and therefore it is allowed in the sum of $8,508.25.
Under 3(b) of the plaintiff’s specifications a claim is made for $21,241.37 for “excess cost of pneumatic excavation over dredging caissons #20, 21 and 22.” It is admitted that this work was done in shallow water and that subsurface conditions were known. In other words, the extra charge is predicated upon the fact that the proximity of the two bridges was not known. The only one of the three piers which had to be excavated to a greater depth than appears on the bidding plan was Pier #21 which I have considered under article 1 of the specifications. It being admitted that subsurface conditions were known from a study of the borings when the bids were made I cannot believe that all of this expense was extra and due to the fact that the piers had to be placed near the old bridge. It may have been somewhat more difficult but not to the extent of warranting $21,241.37 extra cost. This claim is disallowed.
Item 4 of the specifications is “actual cost of relocation of Boston & Maine tracks to permit clearance of piers”, $1,-533.02. Counsel inform the Court that this matter has been adjusted between the parties and is no longer an issue in the case.
Item 5 of the specifications is for “money wrongfully withheld by the defendant.”
The Bridge Authority has withheld an amount equal to $200 a day for 156 days, from December 1, 1939, when the contract was to be completed, to May 8, 1940, when a certificate of completion was granted. The plaintiff claims that it seasonably applied for and was entitled to extensions of time more than equal to such delay which should have been granted, viz: 34 days because of serious errors in the bidding plan; 42 days because of material differences encountered in subsurface conditions (pier 14); 42 days because of a railroad accident on September 10, 1939 ; 3 days because of a strike; 36 days because of material differences encountered in subsurface conditions (piers 16, 17 and 18.)
After a study of the evidence, including the letter of the Engineers to the Bridge Authority, dated December 5, 1939, I find that the Contractor is entitled to 34 days extension of time because of errors in the
