What Stahly Engineering & Associates, Inc does

Stahly Engineering & Associates is an employee-owned civil engineering and land surveying firm founded in 1970, headquartered in Helena, Montana, with additional offices in Billings, Bozeman, and Great Falls (Montana) and Cowley (Wyoming). The firm serves municipalities, counties, state agencies (notably the Montana Department of Transportation), federal partners (NRCS), and private developers across Montana and Wyoming with a full-service offering that spans land surveying, structural engineering, transportation engineering, municipal water/wastewater/stormwater design, site development and subdivisions, bridge design, planning and technical review, GIS/database management, and grant writing and administration. It has designed or administered construction on more than 50 bridges over the last decade, delivered subdivision and surveying review services to nearly two dozen Montana communities, and completed over 20 NRCS grassland/wetland preservation projects since 2011.

The firm's underlying technical stack combines traditional civil engineering tools (AutoCAD Civil 3D, GNSS survey equipment, GIS platforms including ArcGIS Online and ESRI Collector) with advanced geospatial acquisition capabilities — a UAV-based ROCK R3 Pro LiDAR system capable of 640,000 points per second at 2 cm vertical accuracy, UAV photogrammetry, sonar bathymetry for shallow-water and riverine surveys, and terrestrial 3D laser scanning for as-built documentation. These feeds feed an in-house differentiated deliverable called "Smart Map," an interactive multi-layer mapping platform that integrates infrastructure, easement, parcel, and water-rights data for municipal clients. The firm also retains in-house grant writing and administration expertise spanning federal and state programs (MCEP, USDA Rural Development, CDBG, HOME, RRGL, WRDA, FLAP, CTEP), enabling it to act as both engineer and funding administrator for small communities.

Stahly generates revenue through project-based professional service fees (hourly rates, fixed-price project fees, and ongoing contract arrangements) and operates an exclusive direct-engagement go-to-market model via five regional managers and senior engineers. The customer base is overwhelmingly public-sector and project-driven, with RFP-driven acquisition for government work and relationship-driven engagement for long-term county engineering contracts; private developer work is supplemented through site development and subdivision services. Marketing is built on regional brand recognition (Best Engineering Firm in Montana, four consecutive years), ACEC engineering excellence awards, ESOP-driven recruiting, and community involvement.
