From the earliest days of construction until only a few months ago, each written specification was different from every other. Here and there a local organization had made strides in producing some uniformity, but no semblance of national uniformity existed. Finally, a national organization- the Construction Specifications Institute- took a look at the problem, evaluated the difficulties, and devised a solution to the mare's nest of confusion which has surrounded the specification field for so long. What was the result? Nothing more than a framework for a standard table of contents for construction specifications. The CSI Format does not propose to alter specification practices; it does not change bidding practices or procedures. It does not affect trade jurisdictions. It simply gives the specifier 16 pigeonholes into which he can place each specification section for consistent numbering and location. It enables the specifier to write several sections on a given topic, while retaining the physical closeness that seems so necessary for clarity. During the past two years, CSI has been developing improvements designed to clarify the Format and to make it more useful and the following refinements are planned: (1) a list of typical section titles in a preferred arrangement, for use by those who want a standard point of departure in projects where a fixed sequence is practicable; and (2) an arrangement for the contents of specification sections- an internal section "format" that would become relatively standard.
