The Construction Manual provides information and guidance to construction personnel who are responsible for the day-to-day supervision and operations of the state's highway construction projects.

The manual is not a part of the contract and does not supersede the Standard Specification for Road and Bridge Construction, Supplemental Specifications, Special Provisions, plan details or notes. It is used to clarify these documents for the purpose of standardizing procedures and assuring adequate and uniform quality control and contract administration.

Users are encouraged to inform the Bureau of Construction of any inconsistencies, errors, or new ideas so that the manual may reflect the best and most up-to-date information practical. Form BC 2371, Construction Manual Corrections and Comments, is provided to submit this data.

Files posted on these pages are current and current as of the 2006 issuance. To review a summary of the changes implemented in the 2006 manual see the Preface.
