NIGP 91104: C.i.p., Architect/Engineer Extra Services

NIGP 91104 C.i.p., Architect/Engineer Extra Services, is an Item code. State and local governments procure architect and engineer supplementary services—facility assessments, commissioning, condition evaluations, space planning, retrofit design, and construction administration support—as add-on or standalone engagements that fall outside routine design or engineering contracts. Recent solicitations show this code capturing specialized architectural and engineering work tied to asset management, infrastructure resilience, and facility upgrades.

Issuing bodies span city planning and public works departments, county transportation and facilities offices, airport authorities, transit agencies, school districts, regional water authorities, and state higher-education systems. Cities of Orlando, Arlington, and Bend; Seminole County and Harris County; Broward County Transportation; the University of Texas System; and the Georgia Department of Transportation appear multiple times. Solicitation types are predominantly RFQ (Request for Qualifications) with some RFP (Request for Proposals); notice types include qualification-based selection under Florida's Consultants' Competitive Negotiation Act and comparable statutes. Representative recent opportunities include Seminole County's building commissioning services for multiple county facilities across mechanical, electrical, plumbing, and building automation systems (RFP, October 7, 2026 response due); the City of Norwalk's transfer station building and property evaluation (RFP, November 3, 2026); and Denton County's as-needed materials testing and geotechnical services for construction projects (RFQ, October 29, 2026). Geographic activity clusters in Florida (Orlando, Seminole County, Lee County), Texas (Denton, Arlington, Brazos River Authority, Waco, San Antonio area), Georgia (Atlanta, Glynn County, Albany, Dalton), and scattered activity in New Mexico, Oregon, Connecticut, Michigan, and Idaho. Work scopes increasingly emphasize post-construction verification, facility condition assessment, energy efficiency retrofit guidance, resilience planning (flood mitigation, seismic compliance), and integration with construction manager-at-risk or design-build delivery methods. Compensation structures shift toward time-and-materials with not-to-exceed ceilings and cost-plus-multiplier models under federal grant funding constraints.
