1. General Construction Notes

a. All construction work shall conform primarily to the most recent edition of the

TxDOT Standard Specifications for Construction and Maintenance of Highways, Streets, and Bridges (2024).

For items not addressed in the TxDOT Specifications, the City of Amarillo Standard Specifications shall govern. The City of Amarillo Standard Specifications are available on the Capital Projects and Development Engineering Department page of Amarillo.gov. In the event of a conflict where both TxDOT and City of Amarillo specifications apply, the TxDOT requirements shall govern unless otherwise directed by the Engineer. If an item is not addressed in either, the Supplementary Specifications shall apply.

Refer to Plan Sheet 4 – Quantity Summaries and Section 01025 Measurement and Payment for TxDOT, City, and Supplementary items. Measurement and Payment specified in Section 01025 Measurement and Payment shall govern over TxDOT and City of Amarillo specifications.

b. Removal of Construction Debris:

Asphalt, concrete, structural steel, dirt, brush, brick and debris to be removed from the project will not be allowed to dump at the City landfill facility. Other debris can be taken to the landfill at no charge if the Contractor has a current permit from the Public Works Division of the City of Amarillo.

c. All property disturbed and /or damaged by the Contractor outside the limits of the project shall be repaired, at the Contractor’s expense, to the adjacent property owner’s and the City Engineer’s satisfaction.

g. The Contractor shall be responsible for any coordination required for utility adjustments.
