An important part of each section of the technical specifications is the clause providing for the method of payment for the work specified. This is usually the last clause in the section. For example, the last clause in the Baltimore Specifications relating to Rock Excavation, is:
“Payment will be made for the number of cubic yards of rock measured and allowed as above specified at the price of four dollars and fifty cents ($4.50) per cu. yd., measured in place. Payment for rock excavation will be made in addition to the prices bid for excavation.”
115. Special Specifications.—These have to do with problems, methods of construction, or materials peculiar to certain contracts or certain portions of the work. It frequently occurs that the construction of sewerage works will be let out under a number of contracts, or bids will be called for on different alternatives to which the entire Advertisement, Information and Instructions for Bidders, Proposal, and General Specifications are applicable. The special specifications will apply only to the contract in question, e.g., in some work done under the direction of the author, the sewer on one contract came within twelve inches of the surface of a highway. The special specification relating to this piece of construction, was:
“Where crossing under the Chicago Road the pipe sewer shall be embedded in concrete as shown on the contract drawings. The concrete for this purpose shall be mixed in the proportions of one (1) part cement, three (3) parts fine aggregate, and six (6) parts coarse aggregate. Payment for the concrete so used will be made at the unit price stated in the accompanying Proposal.”
In order to avoid confusion the special specifications are either incorporated directly in the Contract form, or follow the Technical Specifications and are grouped according to the contracts to which they apply.
116. The Contract.—The contract is a brief instrument which includes a simple statement of the obligations of each party involved. The following is an example of a form in successful use:
