CONSTRUCTION MANUAL OF INSTRUCTION UDOT specifications are written in CSI (Construction Specifications Institute) three-part format, rather than most other DOTs that use what is referred to as American Association of State Highway Transportation Officials (AASTHO) five-part format. Under both formats, each specification is divided into parts. The fourth and fifth parts of the AASHTO five-part format establish the method of “measurement” and “payment”, respectively, within each specification section. With the CSI format, each specification has only three parts, with “Measurement” (Section 01280) and “Payment” (Section 01282) each having their own section. Each contract includes a project specific Measurement and Payment (M&P) document, separate from the specifications, describing the method of measurement and payment for each bid item included in the contract.
Specification Types Standard Specification Specifications approved by the Department’s Standards Committee for general application and repetitive use.
Supplemental Specification An addition or revision to the Standard Specifications that has been approved by the Department’s Standards Committee.
Special Provision A unique specification or a modification or revision to a standard specification applicable to an individual contract. In the event of discrepancies between information contained in the plans and specifications, the governing ranking of the contract documents indicating which takes precedence is described in Section 00727.
Definitions (Reference Section 00570) Section 00570 includes abbreviations and definitions for commonly used contract terms. (See also Abbreviations and Acronyms in the Appendix)
Bidding Requirements and Conditions (Reference Section 00120 and Policies and Procedures 08B-01, 08B-12, 08B-27) Section 00120 establishes the conditions under which bids are accepted by the Department and describes the Contractor’s responsibility for understanding the plans and specifications and knowledge
