Structural Engineering Business
Development in St. Louis
Specialist firms where the principals are the product, and their time is too valuable for cold outreach.
The 2022 Census County Business Patterns records 454 engineering-services establishments in the St. Louis, MO-IL Metro Area. The broader architectural, engineering, and related services sector includes 851 establishments. These are employer locations, not a count of independent firms or active opportunities. BD-AEC helps St. Louis structural engineering firms turn market context into focused relationships, positioning, and pursuits.

The market
The St. Louis structural engineering market
St. Louis buys design and construction at a scale that punches above its metro size, with federal money leading the way. The $1.7 billion Next NGA West campus for the National Geospatial-Intelligence Agency opened in 2025 and anchors a growing geospatial cluster around GeoFutures, Cortex, and T-REX, while Boeing is mid-build on a $1.8 billion expansion for its F-15 and T-7 lines and has moved its Defense headquarters back to the region. Healthcare is the other engine, led by the BJC HealthCare and Washington University Medical Campus Renewal and SSM Health's new Cardinal Glennon and Saint Louis University hospitals. What makes this market its own animal is that the biggest builders are homegrown: Alberici, McCarthy Building Companies, and Clayco headquarter here, and HOK, one of the largest design firms in the world, was founded here. Winning runs on being known to those owners and primes across a bi-state metro, not on the low number from a stranger.
The 2022 Census County Business Patterns counts 454 engineering-services establishments in the St. Louis metro and 851 architectural, engineering, and related services establishments overall. The data describes employer locations in the metro. It helps frame the market; it doesn't measure open projects, revenue, or how many firms are competing for an individual pursuit.
The dynamics
How structural engineering firms win work, and why BD slips
How the work is won
Structural work runs on a referral network of architects, contractors, and repeat owners. There is rarely a public RFQ; you are selected because a designer or builder already trusts you. That makes business development almost entirely about staying top-of-mind with the firms that feed you work, and steadily widening that network of referral sources.
Who buys it: Structural firms are hired primarily by architects and general contractors who pull them onto project teams, plus building owners and developers on direct commissions. The work is won as a trusted sub-consultant: the architect or contractor brings you in because they know your detailing is clean, your turnaround is reliable, and you make them look good to their owner.
Why BD slips
The principal structural engineer is the firm’s entire reputation, and also its only business developer. Their expertise is exactly what makes the firm valuable, and exactly why pulling them off engineering to nurture architect relationships is so expensive. When they get heads-down on a deadline, BD stops cold, and the referral network goes quiet.
Your engineers bill $300 an hour. They shouldn't be the ones chasing the next St. Louis project.
The fix
What an embedded BD department does for a St. Louis structural engineering firm
An embedded BD team connects the firm to its referral network: keeping architect and contractor relationships warm, surfacing teaming opportunities early, and backing each pursuit with positioning and creative support while principals focus on technical work.
Pursuits we own
Architect and design-firm teaming relationships
General contractor and design-build pursuit teams
Repeat-owner commercial and institutional commissions
Specialty and forensic / restoration engagements
Developer relationships for vertical construction
The policy
Is the St. Louis structural engineering seat open?
BD-AEC represents one firm per discipline, project type, and market. By policy, Scott won't run business development for two structural engineering firms competing for the same St. Louis work. It's an ethical line that protects every client's pipeline, and it means each market seat is genuinely scarce.
If you're a St. Louis structural engineering firm doing $500K to $20M in revenue and your principals are still carrying business development themselves, the seat may still be open. The only way to know is to ask.
