Standard Specifications

The Standard Specifications are those specifications listed in the department’s specifications book entitled Standard Specifications for Construction and Maintenance of Highways, Streets, and Bridges adopted November 1, 2014. The General Requirements and Covenants (Items 1–9) are required for all contracts. Specifications for construction bid items or reference items usually address six areas: description, materials, equipment, construction methods, method of measurement, and method of payment. The Standard Specifications must be used unless alternative Special Specifications or Special Provisions have been approved for use through the Roadway Specification Section (CST_RDWY_SPECS). Modifications to Standard Items 1 through 9 require the approval of the administration.

They may introduce a new description, materials, miscellaneous classification, construction methods, equipment, measurement, and/or payment articles. Special Specifications may be completely new specifications or the modification of previously approved specifications. Three types of Special Specifications exist:
