Question List
Subject: VDOT ROW Type: Other
Question Date: 8/19/2022 12:46:04 PM
Will there be a VDOT ROW, laydown, or staging area available for Contractor use for immediate boat access and staging adjacent to the bridge?  
Answer   Date: 8/22/2022 11:49:52 AM
VDOT does not intend to provide a laydown or staging area to the contractor as the work is anticipated to be completed from a barge below the bridge and not from the roadway.  
 
Subject: Beam Repairs Type: Plan
Question Date: 8/19/2022 11:43:46 AM
Sheet 6 of 9 on the Contract Drawings identifies the beam repair locations, all repairs are on beam 2 and 3. However by conducting a field visit, there is a significant amount of repairs throughout the structure. Why is VDOT only focusing on Beam 2 and 3? Is Vdot going to address the repair areas on a different contract?  
Answer   Date: 8/22/2022 11:50:40 AM
This contract targets only the beams on Sheet 6 for repair due to loss of strength. Other beams are not included in the scope of work.

Will water abrasive blasting be permitted? If so, will the waste water require treatment prior to discharge/disposal into the James River?  
Answer   1 previous answer(s) Date: 8/22/2022 11:44:15 AM
Water abrasive blasting is permitted if proper protections are made by the Contractor.  The Contractor shall comply with all applicable laws and ordinances, and as provided for in the Plans and Specifications, including Section 107.16.  Any material or debris from the bridge shall not be allowed to fall into the river.  Contractor is to ensure moisture content of the concrete is in compliance with the epoxy manufacturer’s recommendations for installation.

Please refer to Section 412.03(s) of the Specifications for concrete surface preparation for the FRP and to Section 416 for the EP-3B/EP-3T waterproofing on concrete.  Tolerances shall also be in compliance with the recommendations of the FRP system manufacturer.  ICRI CSP 3 or smoother textures, as defined by ICRI 310.2R, are recommended by the Engineer for the concrete under the FRP.

Please confirm it would be allowable to leave barges in place, if spudded but not anchored to bridge.  
Answer   Date: 8/22/2022 11:46:18 AM
Please review the Plan notes and Specifications regarding floats and barges. Barges may be spudded in place but must be sufficiently secured so as not to allow the barge to come into contact with the bridge structure. During severe weather, the barges shall be removed as required by the Plan notes.

No.  NBIS inspections shall be in accordance with Section 430 of the Specifications and may occur in 2023 if the work is completed.  
 
Subject: Concrete Repairs Under Live Loads Type: Specifications
Question Date: 8/9/2022 3:43:44 PM
Based on specification 412.03 (page 554 and 567), it appears that no concrete repairs shall be performed within a span lane that is under traffic unless approved by the Engineer or unless supported by an approved temporary support system. Please confirm that these concrete repairs will be acceptable to perform while live load is present above? Otherwise, please provide direction and any additional pay items for the traffic control needs and temporary support needs to achieve this specification.  
Answer   Date: 8/12/2022 1:30:40 PM
The Plans precede the Specifications. Based on deteriorated concrete areas described in the last inspection report, concrete repairs can be performed with live load on the bridge. The third paragraph of Section 412.03 states that it is the Contractor’s responsibility to maintain the integrity of the existing structure.  
 
Subject: Concrete Repairs Type: Specifications
Question Date: 8/9/2022 3:42:20 PM
Based on the specifications 412.03.2, it appears to limit the repair areas to 30% concrete section removal at a given beam per span. Please confirm this intention of this requirement is to remove the need for temporary support system for the structure.  
Answer   Date: 8/12/2022 1:31:33 PM
Section 412.03(a)2 states that removal of concrete (specifically deteriorated concrete for this project) in the tension zone of a beam shall be less than 30% of the span length at any one time. The third paragraph of Section 412.03 states that it is the Contractor’s responsibility to maintain the integrity of the existing structure.
