REQUEST FOR INFORMATION

Request For Information & Government Responses

QUESTION: Would UHP be considered, over sandblasting and chipping, for all concrete surface preparation?

RESPONSE: Contractors shall use hand tools to sound the concrete to determine sound from unsound concrete. Unsound concrete shall be removed via chipping only. Contractors can then be allowed to use Ultra‐High Pressure (UHP) water jetting methods to prepare concrete surfaces, but sandblasting must still be used to prepare rebar surfaces.

QUESTION: For Vertical Concrete repair on abutments: Will the shotcrete process be an acceptable means of repair while providing the specified class of finish?

RESPONSE: While shotcrete will be an acceptable means of repair to vertical concrete repair on abutments, there still must be a troweled finish. As per Spec Section 03 37 13 SHOTCRETE, Paragraph

3.5.1 Ceiling repair can have a Natural Gun Finish.

QUESTION: Sheet S‐301: Can the concrete repair and new curb be completed simultaneously?

RESPONSE: Yes, the concrete repair and new curb can be completed simultaneously.

The Contractor shall employ traffic warning and control devices to control the passage of two‐way traffic for each lane restriction. Lane restrictions for this project are limited to the hours of 7:00 AM to 5:30 PM, Monday through Friday. At the end of these hours, or at the close of work activity for each work day, the Contractor shall remove lane restrictions and restore two‐way traffic.

The work of this project for the Old Route 132 Bridge shall be conducted with the road fully closed for the duration of the work.

This project meets Vermont General Stream Alteration Act Permit standards for projects not requiring a specific permit. Although no permit application is required, the Contractor shall meet the requirements of Section B3 (especially Section B.3.3) of the Vermont Stream Alterations Act General Permit. The General Permit can be found at the following location:
