NIGP 92535: Environmental Engineering

NIGP 92535 Environmental Engineering is an Item code covering the design, assessment, and consulting services that state and local governments procure to support stormwater management, watershed planning, site remediation, drainage infrastructure, and environmental compliance across water quality, MS4 permitting, and restoration projects. Recent solicitations show active procurement across multiple jurisdictions—Florida cities, Georgia counties and the state DOT, California special districts, and others—engaging consultants for stormwater hydraulics and detention design, independent cost estimating for alternative-delivery infrastructure, environmental remediation and investigation, wetland and creek restoration, noise and environmental planning for airports, and master planning for shoreline adaptation and watershed protection. The City of Casselberry, Florida issued an SOQ under Florida's Consultants' Competitive Negotiation Act in October 2026 for stormwater and lakes management continuing services, naming four awardees and capping individual project fees at $200,000; the Georgia Department of Transportation posted multiple RFQs in September–October 2026 for independent cost estimating and CEI services on P3 and alternative-delivery infrastructure projects; and Cobb County, Georgia, Santa Clara County, California, and multiple Florida municipalities solicited design services for pedestrian bridges, trail improvements, and shoreline adaptation. Work spans traditional design-bid-build qualifications-based procurements (RFQ SOQs with two-phase evaluation), continuing services agreements with task authorization structures, and on-call master service agreements. Geographic activity concentrates in Florida (Casselberry, Fort Myers, Daytona Beach, Broward County), Georgia (GDOT, Cobb County, Chatham County, Fulton County, Forsyth County, City of Atlanta), and California (Santa Clara County, West Basin Water District), with secondary activity in Texas, Oregon, and the Northeast.

Evaluation criteria across recent solicitations emphasize firm and personnel experience on comparable projects, past performance references, technical approach and constructability understanding, MBE and local-vendor participation, and resource capacity and workload availability. Many solicitations require current state PE licensure, GDOT or equivalent DOT prequalification in specific area classes (roadway design, bridge design, erosion control, environmental documentation), and compliance with prevailing wage, E-Verify, conflict-of-interest, and federal debarment rules where applicable. Cost structures vary widely—lump sum or cost-plus-fixed-fee for discrete design projects, hourly rates not-to-exceed for task authorization work, and time-and-materials for on-call professional services with annual rate escalation caps (typically 3% or CPI, whichever is lower). Insurance requirements are standard across the sector: professional liability ($1–5 million per claim), commercial general liability ($1–2 million per occurrence), and workers' compensation at statutory limits. Procurement timelines extend two to four months from RFQ/RFP posting to SOQ due dates, with selection committee review, optional presentations, and contract execution occurring over an additional four to six weeks.
