PREFACE

Delete the Preface and substitute the following:

These Standard Specifications for the Construction of Roads and Bridges on Federal Highway Projects are issued primarily for constructing roads and bridges on Federal Highway projects under the direct administration of the Bureau of Land Management. These specifications are cited as "FP-14" indicating

"Federal Project" Standard Specifications issued in 2014 and contain both United States Customary and

Metric units of measure.

When designated in a contract, the FP-14 becomes part of the contract and binding upon all parties to the contract. Construction contracts of the Bureau of Land Management are also governed by the following regulations:

● Federal Acquisition Regulation (FAR), Title 48, Code of Federal Regulations, Chapter 1

The FAR regulations are not included in the FP-14. A complete copy of the FAR is available from the

Superintendent of Documents, Congressional Sales Office, U.S. Government Printing Office, Washington, DC 20402.

U.S. Customary units of measure are used in the FP-14 as provided in the November 25, 2008 Memorandum from Jeffrey F. Paniati entitled Update on Metric Use Requirements for FHWA Documents. Metric units are noted in parentheses following the U.S. Customary Units. The references to Metric or Metric units apply only when the project or portion of the project expressly calls for Metric units of measure.
