Most specifications are written with the intent to be very specific in providing a firm disposition of any dispute which may arise. Being human, however, the engineer or architect protects both himself and the owner with a liberal use of terms such as: "to the satisfaction of the engineer," " in a workman-like manner," and " the contractor shall thoroughly investigate." The theory being that any unexpected difficulty is the responsibility of the contractor. The phrase "workman like manner" seems to have as many definitions as there are people who interpret it. A provision that work shall be done in a good and workman like manner relates to the things specified to be done, and does not impose on the contractor the duty of doing acts or taking precaution which ought to have been, but were not, provided for in the plans and specifications. The determination of what is, or is not, provided for in the plans and specification then becomes a question of fact rather than law, but the interpretation of these facts is necessary to determine liability of the parties. Most specifications state something to the effect that the engineer or architect is empowered to make final determination of disputes between the owner and contractor or to determine the intent of the specifications. The courts hold, as a general rule, that this grant of power does not include authority to construe the contract. However, a specification provision which is not clearly written may not be construed by the engineer in accordance with what he might have intended at the time he wrote it. The meaning of the words, as written, no what the writer thought he was saying -is the determining factor. For example, an engineer required the contractor to pay of the cost of inspecting concrete at the plant, when the contract in plain terms provided that all original test were to be paid by the owner. This interpretation by the engineer was reviewable a reversed by the court, even though the contract said the each and every difference respecting the plans and specification should be finally determined by the engineer.
