Architect-Engineer (A-E) Flood Control Engineering Services – Task Order Contracts

The County of Orange and the Orange County Flood Control District are requesting qualifications for Architect-Engineer (A-E) flood control engineering services to establish a pre-qualified vendor list for county-wide and district-wide task order contracts, with responses due August 13, 2026 at 2:00 PM. This is a pre-qualification solicitation; no cost proposal is required at the SOQ stage, and pricing will be negotiated with selected firms upon written request within ten business days of notification.

Respondents must demonstrate a minimum of three years in business in California, prior similar work in Southern California, and employ duly registered California Professional Civil Engineers. Required services include flood control engineering, hydraulic and hydrologic analyses, design, plan checking, floodplain management, levee recertification, dam inundation studies, letter of map revision preparation, and community rating system support. All deliverables must be prepared under direct supervision and responsible charge of licensed Professional Engineers with appropriate discipline stamps. Work must comply with the Orange County Flood Control Design Manual, Orange County Hydrology Manual, AASHTO Design Manuals, FEMA specifications, and California Labor Code requirements, including prevailing wage obligations.

Evaluation is weighted as follows: qualifications and experience (40 percent), key personnel and staffing (20 percent), availability to perform services (25 percent), SOQ organization and completeness (12.5 percent), and degree of compliance with the County model contract (2.5 percent). Respondents must provide a minimum of five references, including at least three from comparable public sector entities within the past five years. SOQs exceeding 25 single-sided pages will be disqualified. Respondents submitting exceptions to the model contract receive zero points on the compliance criterion.

Contracts will carry a three-year term. The County reserves the right to make multiple awards. Compensation will be structured as time-and-materials with fully burdened hourly rates for various classifications; no price increases are permitted during the contract term. Insurance requirements include $1,000,000 per occurrence commercial general liability, $1,000,000 auto liability, and $1,000,000 professional liability. Questions are due July 16, 2026 at 2:00 PM.
