UNSPSC 81103003: Special periodic survey

Special periodic survey (SPS) is a five yearly classification requirement. SPS's can be carried out in line with an under-water inspection in lieu of drydocking (UWILD) and is unique to each vessel or rig

UNSPSC 81103003 Special periodic survey is a Commodity code that captures recurring inspection, testing, assessment, and diagnostic services that state and local governments commission on fixed schedules or as needed for equipment, facilities, infrastructure, and vessels. Recent solicitations show the code applied to marine vessel maintenance inspections, IT infrastructure testing and commissioning, landfill construction quality control testing, and shipyard services assessment — work ranging from preventive maintenance diagnostics on patrol boats to post-construction testing and certification of newly installed systems. The issuing bodies span county governments, state environmental agencies, and local authorities managing specialized assets (marine vessels, IT infrastructure, waste management facilities), with no single repeat buyer visible in recent postings. The work is typically bundled into construction, renovation, or asset-management contracts where inspection and testing form a required component rather than standing as independent service lines.

Recent activity appears in Texas, Georgia, California, and Maryland. The County of Ventura, California solicited RFP 6229 for Sheriff's Boat 1 Maintenance Services (due June 16, 2026), encompassing scheduled preventive maintenance inspections and diagnostics on a patrol vessel including 100-hour and 300-hour service intervals, mechanical and propulsion system testing, and hull inspections. DeKalb County, Georgia posted ITB 2026-076-ITB for reconstruction of the DeKalb Tennis Center (due July 13, 2026), including testing and documentation of a new IT and Low Voltage Infrastructure system. The Maryland Environmental Service solicited competitive sealed bids for Brown Station Road Sanitary Landfill Area C Infill Cell C-2-3 construction (due April 24, 2026), requiring an independent Construction Quality Control testing firm to manage inspections and geosynthetic material verification throughout the project. A Texas solicitation (TAMUGITB260121) for a pool of vendors providing shipyard services (due July 28, 2026) carries insufficient scope detail to assess alignment with the code.
