UNSPSC 81111503: Systems integration design

UNSPSC 81111503 Systems integration design is a Commodity code encompassing the detailed architectural design, planning, and integration coordination for complex software and IT systems serving state and local governments. Recent solicitations under this code show state and local buyers procuring end-to-end system integration services for enterprise-scale platform migrations, cloud infrastructure transitions, legacy system replacements, and multi-component technology consolidations where specialized design and coordination expertise is essential to project success.

State agencies, counties, cities, and special-purpose districts issue these solicitations across varied verticals. The California Department of Technology solicited system integration design for WaterTAP 2.0, consolidating eight legacy drinking water compliance systems into a single Salesforce-based cloud platform serving 65,000 users; the Florida Department of Highway Safety and Motor Vehicles entered into a single-source engagement with Presidio Networked Solutions for Interactive Voice Response system replacement and integration services supporting 1 million annual calls; Broward County Aviation Department requested AI-enabled system integration and implementation for X-ray screening at Fort Lauderdale-Hollywood International Airport; and Valencia College issued an RFI for IT Service Management and Customer Service Management platform design and integration. Missouri, California (EDD), Utah, Texas, and Florida jurisdictions have posted or recently awarded comparable system integration design work tied to ERP implementations, cloud migrations, and legacy-system sunsetting. Geographic activity spans California (water systems, employment services, notary administration), Florida (higher education, transportation, airport operations, motor vehicle services), Missouri (ERP transition), Texas (health and human services), and scattered municipal and county procurement across the Southeast and Mountain West. The WaterTAP 2.0 RFP (California Department of Technology, due December 2, 2026) and the Florida Department of Highway Safety and Motor Vehicles' sole-source IVR integration (estimated value $3.5 million over three years, place of performance Tallahassee) represent typical large-scale, mission-critical work under this code. The Broward County Aviation AI-enabled system integration (RFP BLD2131742P1, due October 26, 2026) demonstrates demand for specialized integration of emerging technologies into existing airport infrastructure. Buyers consistently require demonstrated experience with large-scale implementations, Salesforce or Oracle platform expertise, multi-system data migration capability, and organizational change management on comparable-scale projects.
