4.2.1 Standard Specifications

The Standard Specifications are listed in the department’s current specifications book entitled
Standard Specifications for Construction and Maintenance of Highways, Streets, and Bridges
. All Standard Specifications are assigned a
three-digit Item Number
 for organizational and reference purposes (e.g., Item 110 - Excavation). Each Specification is outlined by six basic articles:
  • Description;
  • Materials;
  • Equipment;
  • Construction or Work Methods;
  • Measurement; and
  • Payment.
The Standard Specifications must be used unless alternative Special Specifications or Special Provisions have been approved for use.
The General Requirements and Covenants (Items 1–9) of the
Standard Specifications for Construction and Maintenance of Highways, Streets and Bridges
are required for all construction contracts. Modifications to Standard Items 1-9 require the approval of TxDOT Administration and the approval of a Special Provision (See
Section 4.2.3
for additional information on Special Provisions).
