Abstract

The term specifications (usually plural) is defined (Webster's Unabridged Dictionary) as "A written or printed description of the work to be done, forming part of the contract and describing qualities of material and mode of construction and also giving dimensions and other information not shown in the Drawings". But the Dictionary description will not suffice, Rosen, H.J (1967). As we explore the full meaning of the Term, we discover many areas solely within the province of the specifications which extend far beyond a mere elaboration of the drawings. For example, the specifications alone, as a contract document prepared by the Architect, set forth legal requirements, Insurance requirements, bidding procedures, alternates, options, subcontractor limits, and inspection and testing procedures. In many instances design decisions cannot be shown on the drawings, and the specifications are the only vehicle through which these design considerations may be transmitted to the contractor. Specifications are written for use by the Estimator in the contractors office who will procure the materials and equipment described in the specifications. They are also written for the project representative or inspector, who must be given a document which will aid him in supervising and directing the work. They are written for the owner, who would like to know what he is buying and what he is entitled to receive. They are written for the sub-contractors, so that each can readily discern the scope of his contract. They are written for the manufacturers of building materials and equipment, so that the grade and type are clearly defined with respect to the many variations they may manufacture.
