Fenstermaker

What Fenstermaker does

Fenstermaker (C. H. Fenstermaker & Associates, L.L.C.) is a privately held, multi-disciplinary professional services firm founded in 1950 and headquartered in Lafayette, Louisiana. The firm operates across three core service lines — Survey & Mapping, Engineering, and Environmental Consulting — delivered through approximately ten offices spanning Louisiana (Lafayette, Baton Rouge, New Orleans, Lake Charles, Shreveport/Bossier City), Texas (Houston, San Antonio, Midland), and Mississippi (Ocean Springs). It serves federal, state, and local government agencies alongside enterprise clients in oil & gas, petrochemical/LNG, transportation, ports, utilities, and industrial sectors, with a pronounced concentration along the U.S. Gulf Coast. Family ownership continues into the fourth generation, with Bill Fenstermaker serving as Chairman & CEO and Charles Fenstermaker as President (since February 2019).

The firm's technical stack centers on advanced geospatial and sensing technologies rather than software platforms: topographic, hydrographic, and bathymetric surveys; LiDAR (including drone-mounted and the TrueView GO handheld unit); 3D terrestrial laser scanning for digital twin generation; multi-beam bathymetric sonar (Norbit iWBMSh); and UAS-based data capture. Its principal proprietary technology is Map Analyst, a custom GIS platform deployed across multiple client engagements including parish assessor systems, oil/gas field as-built databases, and Lafayette Parish 911 dispatch integration. Notable project outcomes include 5,200 laser scans of a crude refinery completed in two months with four field crews, and the ongoing $25.4 million Mermentau Basin Inundation Relief Project in partnership with Ducks Unlimited and HDR.

Fenstermaker generates revenue through project-based professional services engagements with quote-driven pricing determined via proposals, RFP responses, and direct client negotiations. Contracts typically span multiple years and are secured through enterprise field sales to government agencies and energy/industrial clients across the Gulf Coast. The firm does not disclose pricing publicly, and revenue is not reported; however, ten office locations, 251-500 employees, and a portfolio of large multi-year government and infrastructure programs support a mid-market professional services revenue base. The firm markets through a content-led approach including a blog, podcast, news coverage, LinkedIn presence, and industry event participation, while distribution is entirely direct through professional engagement.
