The Virginia Department of Transportation (VDOT) is soliciting bids under IFB-161022 for Remote Concrete Sounding services across nine statewide districts. The contractor will be responsible for identifying delamination on bridge elements located 25 feet or less above the ground or waterline where conventional access is impractical. The scope requires using a device to strike concrete in a rectilinear pattern at least once per inch in the direction of travel, with parallel paths no more than one foot apart. Optional high-resolution imaging may be requested to detect cracks of 0.2 mm or larger. All fieldwork must be overseen by an ASNT Level II certified inspector, and any Unmanned Aerial Systems used must comply with IIM-LD-264, Virginia Code, and 14 CFR part 107. The contract is awarded to the lowest responsive and responsible bidder on a grand total basis. The initial performance period is one year from the date of award, with the option for four consecutive one-year renewals. Key deliverables include personnel certifications submitted prior to work and detailed digital reports provided within 30 calendar days of fieldwork completion. Bidders must submit their responses electronically via eVA by October 13, 2026, and must include a Small Business Subcontracting Plan to be considered responsive, unless they are a DSBSD-certified small or micro business completing all work. Contractors must adhere to strict safety and operational standards, including OSHA and VOSH regulations and the 2011 Virginia Work Area Protection Manual for shoulder closures. Required insurance includes Workers Compensation, $100,000 in Employer Liability, and $1,000,000 in Automobile Liability. Payment is processed within 30 days of invoice acceptance via check, ACH, EDI, or P-Card. The contractor is prohibited from demobilizing from a site until VDOT has verified and accepted the work in writing.
