Opinion by
The Pennsylvania Turnpike Commission, on April 17, 1939, advertised for bids on the construction of a certain section of their turnpike, which bids were due in the office of the Turnpike Commission on April 28,1939. The York Engineering & Construction Company obtained a copy of the plans and sрecifications and made a surfac.e examination of that section of the turnpike, which was as complete an examination as could be made in the short period of time granted in which to file bids. *357 The information contained in the plans and spеcifications indicated the material to be excavated would consist principally of loose earth and approximately 50,000 cubic yards of limestone, visible at the east end of the section. The York Engineering & Construction Company was awardеd the contract and entered into a formal agreement to perform the work. On the plans and blueprints were set forth the estimated amounts of grading quantities. * In the contract it is set forth under Instructions to Bidders, “Each bidder shall familiarize himself with all of the attached forms, Instructions, General Conditions, Specifications, Drawings, etc., as he will be held responsible to fully comply therewith. Each bidder must visit the site and acqaint himself with conditions affecting the work.” And in Section 36 of the contract it is provided: “The bidder’s attention is called to the fact that the estimate of quantities of work to be done and materials to be furnished under these specifications, as shown on the proposal form, is approximate and is given only as a basis of calculation upon which the award of the contract is to be made. The Commission does not assume any responsibility that the quantities shall obtain strictly in the construction of the project nor shall *358 the contractor plead misunderstanding or deception because of such estimate of quantities оr of the character of the work, location or other conditions pertaining thereto. The Commission reserves the right to increase or diminish any or all of the above mentioned quantities of work or to omit any of them, as it may deem necessary.” And in Section 37 it is provided: “Wherever subsurface materials information is indicated on the drawings it is understood that it was obtained in the usual manner and with reasonable care, and the location, depths and the character of the material have been recorded in good faith. There is no expressed or implied agreement that the depths or the character of the material have been correctly indicated and bidders should take into account the possibility that conditions affecting the cost or quantities of work to be done may differ from those indicated.”
Owing to the magnitude of the undertaking, four to eight weeks would have been required for a complete subsurface investigation and the engineering company was, therefore, compelled to rely on the plans as to subsurface conditions. These plans showed a factor of fill plus shrink, which indicated the character of the material to be excavated was largely loose earth, as only loose earth shrinks when mechanically moved from one place to another. The engineers for the Turnpike Commission had investigated the subsurface conditions of this section and found it to be predominantly rock, which should have shown on the plans as fill plus swell. After the contractor commenced excavating, it was discovered that the subsurface, at the point of excavation, was limestone rock containing clay seams, and this condition prevailed at each subsequent cut into the subsurface. The additional expense of working this unanticipated type of subsurface material was much greater and, on account of the swell in the waste excavation, also increased its cost of removal. The arbitrators found that the contractor could not, with certainty, determine the extent of the misrеpresentations so as to justify stopping *359 the work prior to its completion. The contractor filed a claim with the Turnpike Commission, calling their attention to the errors in the specifications as well as advising the Commission that there was not sufficient time between the bid advertisement and the opening of the bids to make a subsurface investigation, and that in preparing its bids the contractor had relied on the subsurface information furnished with the plans. Under the contract, the matters in dispute were referred to the Board of Arbitrators. There was no dispute relative to quantities, but pertained entirely to the question of the subsurface material, the contractor claiming it was misrepresented on the plan. The Board of Arbitrators found the plans furnished by the Turnpike Commission misrepresented the character of the subsurface material, which amounted to a breach of contract, and awarded the appellee $149,870.84, with interest at 6% from and including June 1,1940. A petition was filed on behalf of the Turnpike Commission to vacate, modify or сorrect the award of the arbitrators and, after hearing, the court below affirmed the award, but disallowed interest thereon.
The Act of April 25,1927, P. L. 381, 5 PS 306, under which this proceeding was instituted, places an award on the same footing as the verdict of a jury; mistakes of law may be rectified on appeal;
Philadelphia Housing Authority v. Turner Construction Company,
In
Hollerbach v. United States,
The court below modified the award of the arbitrators by disallowing interest. Under Section 4 of the Act of Muy 21, 1937, P. L. 774, it is stated: “The commission is hereby constituted an instrumentality of the Commonwealth, and the exercise by the commission of the powers conferred by this act in the construction, operation and maintenance of the turnpike shall be deemed and held to be an essential governmental function of the Commonwealth.” In
Culver v.
Commonwealth,
We have examined all of the assignments of error and find no reason for disturbing the proceedings of the arbitrators as modified by thе court below.
Judgment affirmed.
