Business developmentforSt. Louis AEC firms.
BD-AEC is an embedded, fractional business development director for St. Louis architecture, engineering, and construction firms. Your engineers bill $300 an hour, so they should not be running your pipeline. We run it, with the relationships that win federal, healthcare, and public work before the RFQ ever drops.
The St. Louis market
Who buys design and construction here
St. Louis is a deep, headquarters-heavy AEC market with more capital in play than its size suggests, split across Missouri and Illinois. About 851 design and construction firms compete here, including 454 engineering firms, chasing a pipeline anchored by federal, healthcare, and public owners who buy on reputation.
St. Louis buys design and construction at a scale that punches above its metro size, and the signature driver is federal. The $1.7 billion Next NGA West campus, the National Geospatial-Intelligence Agency's new 97-acre home in north St. Louis, opened in 2025 and anchors a fast-growing geospatial cluster around GeoFutures, the Cortex Innovation District, and T-REX. Boeing is mid-build on a $1.8 billion St. Louis expansion, including a 1.1 million square foot advanced combat aircraft facility for its F-15 and T-7 lines, and has moved its Defense, Space and Security headquarters back to the region. Healthcare is the other engine: BJC HealthCare and the Washington University Medical Campus are running a multi-year Campus Renewal led by the new Plaza West Tower at Barnes-Jewish, while SSM Health is building a replacement Cardinal Glennon Children's Hospital and finished a new Saint Louis University Hospital. Public owners keep the base full, from MoDOT and the roughly $3 billion Lambert consolidated terminal program to Metro Transit and the Metropolitan St. Louis Sewer District.
It is also a deep AEC town, not an open one, and the biggest names are homegrown. National-scale primes headquarter here: Alberici, McCarthy Building Companies, and Clayco all run out of St. Louis, and HOK, one of the largest design firms in the world, was founded here and keeps its headquarters downtown. KAI Enterprises and other established design-build firms hold long relationships across the same owners. The federal, health-system, and public buyers that drive this market select on track record and trust, not the low number from a firm they do not know, and the same primes and program managers recur on pursuit after pursuit. Being new to St. Louis is not enough; you have to be known to the people who decide.
That is the opening for a fractional BD director, and BD-AEC takes St. Louis on as one of the select major markets it serves. The pursuits worth winning here run on relationships that take years to build, and a principal who is billable cannot build them on the side. St. Louis is a market a dedicated director works deliberately, not one BD-AEC pretends to run from a local storefront. A director who owns the pursuit, the teaming, and the owner relationships is the honest way into a field this competitive.

Why us, here
Why a fractional BD director in St. Louis
St. Louis is one of the select major markets BD-AEC serves beyond its core, and it rewards a dedicated approach. This is a headquarters town where the same federal program managers, health-system facilities directors, and homegrown primes recur on job after job, and where selection runs on reputation rather than the low bid. A fractional BD director who works those relationships deliberately, and honestly represents your firm to the owners who decide, is the difference between a cold proposal and a warm introduction. We're direct about what this is: a market BD-AEC takes on selectively, with a dedicated director as the way in, not a local office pretending to know everyone in town.
By policy, BD-AEC represents one firm per discipline, project type, and market, an ethical line that protects every client's pipeline. For a St. Louis firm, that means an exclusive BD partner who will never walk your relationships across the street to a competitor chasing the same NGA, BJC, or Lambert work.
Questions
Straight answers
Does BD-AEC work the St. Louis market?
Yes, as one of the select major markets we serve beyond our core, not as a local office. We're honest about that. Scott doesn't claim to know every St. Louis owner by name or to run business development from a storefront in town. What we bring is a dedicated fractional director who works the federal, health-system, and public owners here deliberately, and represents your firm to the people who decide.
What kind of AEC firms do you represent in St. Louis?
Principal-led architecture, engineering, and construction firms, roughly $1M to $20M in revenue, whose senior people are too valuable to spend their week on business development. By policy we take only one firm per discipline, project type, and market, so we never represent two competitors.
How is a fractional BD director different from hiring a salesperson?
A salesperson cold-calls. A fractional BD director is an embedded, senior partner who owns your pipeline: the strategy, the relationships, the teaming, and the pursuit. You get the expertise of a six-figure BD hire without the full-time salary line.
St. Louis is full of homegrown national primes like Alberici, McCarthy, and HOK. Can a smaller firm still compete?
Yes, but not by being a stranger. The federal, healthcare, and public owners here hire on track record and relationships, not the low number from a firm they do not know. We position your firm with the owners and program managers who decide, so you are the known quantity when the work comes up, and often the teaming partner those primes want, not the outsider underbidding for a seat.
