NIGP 78064: Over-Under (Even Balance) Scales

NIGP 78064 Over-Under (Even Balance) Scales, an Item code, encompasses maintenance, calibration, and supply contracts for mechanical, hydrostatic, and electronic weighing systems deployed across municipal operations. State and local governments buy preventative maintenance, baseline assessments, NIST-traceable calibration services, and replacement scales and related equipment under this code. Issuing bodies include city departments with infrastructure and utility operations—sanitation, water utilities, police, and animal services divisions—that operate scales at transfer stations, landfills, water treatment plants, police facilities, and weigh stations. Vendors pursuing this code must typically hold minimum five years of documented weighing systems maintenance experience, maintain NIST-traceable calibration certifications, demonstrate satisfactory safety ratings, and provide 24/7 service availability with local facility presence.

The City of Dallas posted a representative opportunity (Solicitation BYZ2600029777, Request for Competitive Sealed Proposal, due April 24, 2026) for a three-year ID/IQ service price agreement with two one-year renewal options covering comprehensive maintenance and calibration for Sanitation Services, Dallas Police, Dallas Water Utilities, and Dallas Animal Services. The evaluation framework awards 100 points across experience and qualifications (20 points), project approach (15 points), mobilization capability (10 points), cost (30 points), local preference (5 points), and compliance with Dallas's Developing Regional & Inclusive Vendor Enterprises (DRIVE) policy (20 points). The procurement carries contract-specific SBE subcontracting goals and a wage floor of $23.06 per hour for all employees; contractors must maintain Workers' Compensation, Business Automobile Liability, and Commercial General Liability insurance with the City named as additional insured. A pre-proposal conference was held March 24, 2026, with written questions due April 1, 2026, and proposals due April 24, 2026, at 1:00 PM.
