SECTION 01020 – PENNDOT PUBLICATION COORDINATION

1.01 MINIMUM STANDARDS

A. All work in State Highway Right-of-Way shall be constructed in accordance with the requirements of:

1. PennDOT Publication 408 Specifications

2. PennDOT Publication 35 Bulletin 15 – Approved Construction Materials

3. PennDOT Publication 72M – Roadway Construction Standards

B. It is the intent of the Contract Documents that the requirements of the above listed

PennDOT Publications are the minimum quality of work and minimum quantity of work to be provided by Contractor. The Contract Documents, including but not limited to the Drawings and Specifications, may require additional work, additional material, a higher quality material, specialized equipment and/or other additional quantity or quality of work to complete the construction.
