SECTION 430—NBIS INSPECTION USING UNDER BRIDGE INSPECTION DEVICE
430.01 Description
This work shall consist of furnishing an OSHA compliant under bridge inspection device, including qualified operator, to facilitate the inspection of bridge structures by Department inspectors or designated consultant inspectors prior to opening such bridge structures or partial bridge structures, based on phase construction, to public traffic. The under bridge inspection device shall be of sufficient size, capacity, and reach to provide access to all areas of the specified bridge structure(s) or partial bridge structure(s) for inspection purposes. The Contractor shall provide VDOT inspectors full access to bridge structures for the National Bridge Inspection Standards (NBIS) bridge initial/inventory and/or final acceptance inspection before the bridge structure(s) or partial bridge structure(s) is opened to public traffic.
430.02 Notification Requirements
The Contractor shall notify the Engineer at least 1 month (30 days) in advance of his requested NBIS inspection date to arrange for NBIS inspection of the completed bridge structure(s) or completed partial bridge structures. If the Department is able to arrange to supply it’ s under bridge inspection device once the request for the NBIS inspection is received from the Contractor, the Contractor will be notified by the Engineer and payment for days/partial days not used will be deleted from the Contract. Advance notice and coordination by each party in scheduling mutually agreeable date(s) and time(s) for NBIS inspection is required due to bridge inspection device and personnel availability as well as associated costs. 429.09
430.03 Rescheduling Inspection
If the NBIS bridge inspection must be rescheduled, the Contractor’ s request for the NBIS inspection will be subject to the next available date of the bridge inspection team within 10 calendar days of the originally scheduled date of the NBIS inspection. If either party must reschedule the inspection, they must furnish the other party at least 7 calendar days advance notice. The under bridge inspection device and qualified operator shall also be available for any subsequent re- inspection(s) (including mobilization) for corrective measures identified in the NBIS bridge inspection, and will be subject to the next available date the bridge inspection team can perform the inspection. If necessary, only the first re-inspection will be paid for in accordance with the pay item herein. Re-inspections thereafter shall be at the Contractor’ s expense. A delay in the NBIS bridge inspection attributable to the Contractor will not relieve the Contractor from his obligation to complete the work within the Contract time limit nor justify a time extension.
430.04 Traffic Control during Inspection
When the Contract has individual pay items to address maintenance of traffic operations, these items may be adjusted to accommodate traffic control necessary for the NBIS bridge initial/inventory and/ or final acceptance inspection(s). In contracts where maintenance of traffic is specified for Lump Sum payment, the Contractor shall plan the work so that the cost for maintenance of traffic for the NBIS bridge inspection(s) is covered in the final percentage of the lump sum payment. Therefore, the final percentage of the lump sum amount bid will not be submitted for payment until after the NBIS inspection(s) has been satisfactorily completed.
430.05 Measurement and Payment
NBIS access, under bridge (Str. No.) will be measured in days or partial days and will be paid for at the contract unit price per day or partial days based on the actual working time required to conduct inspections for the bridge structure(s) specified. This price shall include furnishing an un - der bridge inspection device and qualified operator, mobilization/demobilization, development of a traffic control plan and furnishing traffic control for the NBIS inspection(s) required to perform and fully complete the inspection(s). Time governing payment will commence once the under bridge inspection device and operator are at the inspection location based upon a mutually agreed schedule (date and time) between the Engineer and the Contractor and proper notification in accordance with the requirements herein has been made. Payment will be made under: —————————————————————————————Pay Item Pay Unit—————————————————————————————NBIS access, under bridge (Str. No.) Day/Partial Day————————————————————————————— 430.05
