These specifications are designed to prevent early obsolescend the specifications and controversy in the administration of contra and to encourage increased production and decreased costs consis with high quality work.

The book is issued primarily for use in the construction of roads bridges on Federal highway projects under the direct supervisio the Federal Highway Administration. When so designated in the tract of a project, it becomes part of the contract document, bind upon the parties signatory to the contract. For simplification in re ence, this book may be cited as “FP-74,” indicating Federal proje specifications issued in 1974.

This book contains specifications for those items of work, materia and construction methods that are generally applicable to direct Fe eral highway contracts, but it is adaptable for use by other highw agencies.

Because the highway industry has begun converting to the metr system, this edition of the construction specifications has been dualize to familiarize the user with the Metric System of Measurement. Ti U.S. measurement system is the official measurement system and w govern in all cases.
