A&F Engineering

What A&F Engineering does

A&F Engineering is an Indianapolis-based, privately held civil engineering professional services firm founded in 1966 by Herbert Ayres and Bill Fehribach. The firm operates across four integrated service divisions — Traffic Engineering, Transportation Design, Site Engineering, and Construction Inspection — and delivers end-to-end project support from initial data gathering and analysis through final inspection. Its core technical stack relies on established civil and transportation engineering software platforms (AutoCAD Civil 3D, Synchro/SimTraffic, VISSIM, VISUM, SIDRA, Highway Capacity Software, HydroCAD, HydroFlow, HEC-RAS), with a proprietary bio-inspired methodology ("Ant Colony Traffic Optimization Principle") and standard ITE methodologies for trip generation and forecasting. Projects range from corridor studies and traffic impact fee studies to roundabout, roadway, and highway lighting design, as well as site grading, stormwater management, NPDES permitting, and INDOT-certified construction inspection.

The firm generates revenue through project-based professional services contracts, typically billed per-project or hourly, and is sales-led with a direct-engagement model — no channel intermediaries. Pricing is quote-driven and not publicly standardized; employee compensation ranges disclosed in job postings span roughly $40K to $110K, with engineering roles concentrated in the $70K-$110K band and full benefits including health, 401(k) match, and PTO. Customers are primarily Midwest municipalities, counties, and state agencies (e.g., City of Fishers, City of Indianapolis, Hamilton County Highway Department, Indianapolis Colts) and private developers (e.g., Platinum Properties, Republic Development, Lennar Indianapolis, Scannel, First Internet Bank). Distribution is entirely direct, secured through RFP processes and longstanding relationships, with the firm operating a single headquarters office at 8365 Keystone Crossing in Indianapolis. The company has remained family-led, with second-generation owner Steven Fehribach (P.E.) assuming the presidency in 1996 and presiding over the addition of the civil site engineering department. No external investment, parent company, or acquisition activity is disclosed.
