The degree of inspection of utility construction may vary with the nature and location of the work, as it affects the completed transportation project facility. Certain phases of the work may require a close check to ensure that the transportation project facility will not be adversely affected. The degree of inspection may vary from spot-checking of the overhead installations to continuous and close observation of the installation and backfilling of underground facilities.

The TxDOT Inspector should be careful to ensure that the construction operations are compatible, proceed according to the agreement assembly, and adhere to specifications mandated by appropriate District utility specifications and the appropriate sections of TxDOT’s Standard Specifications for Construction of Transportation Projects, Streets and Bridges or Standard Specifications for Construction and Maintenance of Highways, Streets & Bridges (Metric). Lack of coordination and attention to approved construction methods may result in additional charges, delay in transportation project construction, and possible damage to equipment and injury to personnel.

The following is a partial listing of inspection items to be checked, including, but not limited to:

compliance with State and Federal regulations;
verification of utility survey control and datum;
vertical clearances of proposed underground utility facilities relative to transportation project installations, i.e., storm sewers, roadway subgrades, and drainage structures;
bridge, retaining, and noise wall column foundation locations relative to underground crossings;
vertical and horizontal clearances and alignments of proposed utility facilities;
railroad facilities;
placement of poles, towers, and other similar aboveground installations that violate clear zone design policies.
control of access violations;
encasement or other protective measures;
manholes adjusted to appropriate grades;
bedding and backfilling of all utility excavated areas to appropriate density;
condition of utility materials; and
other highway improvements or structures.
