From Michigan to Florida.
And everywhere worth stopping.

Saginaw is a small, concentrated market where only about 21 engineering firms and 32 AEC firms serve a metro of roughly 190,000, so the people who buy design and construction here already know the people who deliver it. Demand is driven by a few outsized anchors rather than broad development: Hemlock Semiconductor’s CHIPS-backed polysilicon expansion in Thomas Township, Nexteer Automotive’s Saginaw engineering footprint, and the Saginaw Medical Diamond, a riverfront medical campus pulling together CMU’s College of Medicine, two hospital systems, and a new SVSU facility. With so few firms and a handful of repeat owners, winning work here is about being known and trusted, not about underbidding. For a BD practice, that thin competition is the opening: it’s an underserved market where consistent presence and relationships compound fast.

Flint is a small AEC market, roughly 41 engineering firms and 70 design and construction firms across the metro, which makes it underserved rather than crowded, and that is the opening for a focused BD effort. Demand here is unmistakably local: GM’s billion-dollar reinvestment across its Flint plants, including Flint Assembly, the Flint Metal Center, and Flint Engine Operations, keeps industrial and facilities work in play, while the water crisis turned the City of Flint and Genesee County into scrutinized public-infrastructure owners, with the lead service line program now largely complete but water-plant modernization, property restoration, and broader public works still on the table. Winning that work is about trust and a track record on sensitive public projects, not the low bid, because owners and residents here have long memories and watch who delivers.

Detroit is the densest AEC market on the northern end of the corridor, and the buyer base is unusually concentrated: the auto OEMs (Ford’s Michigan Central campus, GM, Stellantis) drive a private capital build that no other metro on this route can match, sitting alongside a healthcare construction boom led by Henry Ford Health’s $2.2B Destination: Grand expansion and Wayne State’s new health-sciences research building. Public work is split across the three core counties, Wayne, Oakland, and Macomb, each with its own road agency plus MDOT’s Metro Region, the Great Lakes Water Authority, and the Wayne County Airport Authority, so a firm has to maintain relationships across a fragmented set of owners to keep a pipeline full. With nearly 1,500 AEC firms competing and large primes like Barton Malow and Ghafari rooted here, winning institutional, municipal, and OEM work in this market is about reputation and a track record owners already trust, not the low number.

Toledo is a manufacturing town first, and that shapes who buys design and construction here: heavy industry like the Jeep-badged Stellantis Toledo Assembly Complex, GM Toledo Propulsion Systems, and the legacy glass makers O-I, Libbey, and Owens Corning, alongside anchor institutions ProMedica, Mercy Health, and the University of Toledo. With 88 engineering firms and 142 AEC firms total in a metro of roughly 644,547, this is a concentrated market where the same primes, plant engineers, and facilities directors recur on project after project. Winning work here runs on being a known quantity to those buyers, not on coming in low against a stranger.

Dayton runs on Wright-Patterson Air Force Base, Ohio’s largest single-site employer, and the defense-engineering cluster it pulls in around it: AFRL, NASIC, and the contractor base working outside the fence. That makes the dominant buyer a federal one, with security clearances, IDIQ vehicles, and prime/sub teaming relationships deciding who wins, not low bids on the open market. Layered on top is a civilian market split between two competing health systems, the University of Dayton and Wright State, and a City of Dayton water enterprise sitting on the Great Miami Buried Valley Aquifer. AEC firms here win by being known to the right primes, agencies, and institutional owners, which is exactly the relationship-building most technical firms have no one dedicated to doing.

The Cincinnati metro spans three states, Ohio, Kentucky, and Indiana, which means AEC firms here navigate three regulatory environments, three sets of public owners, and a fragmented buyer landscape that rewards firms with real local relationships. It is one of the densest AEC markets on the corridor, and competition for institutional, municipal, and private work is correspondingly intense. The firms that win consistently here do it on relationships and reputation, not low bids.

Lexington concentrates Central Kentucky’s institutional and healthcare construction into a single, relationship-driven market: the University of Kentucky, major hospital systems, and a steady stream of state and municipal work. It is a smaller metro than Cincinnati or Atlanta, which makes reputation travel fast. The AEC firms that win here are known quantities, and breaking in without relationships is hard.

Knoxville is a priority expansion market: a growing East Tennessee metro anchored by the University of Tennessee and the Oak Ridge technical economy, with steady population and construction growth that outpaces the BD capacity of most local AEC firms. It is underserved by national business-development consultants, which leaves room for a firm that actually shows up and builds the relationships.

Chattanooga pairs manufacturing investment, the Volkswagen plant and its supplier base, with infrastructure growth and an emerging tech economy, all in a metro small enough that relationships compound quickly. Its position gives AEC firms east-west reach toward Huntsville and the Carolinas, and the market is underserved enough that a disciplined BD effort stands out.

Atlanta is the largest AEC market on the I-75 corridor by a wide margin, a metro of more than six million people with data-center, transportation, federal, and commercial construction running at a scale that dwarfs the rest of the corridor. That scale also means the most competition. Standing out in Atlanta requires a focused BD strategy and the teaming relationships to pursue larger work, not scattershot outreach.

Grand Rapids is a maker town with a research spine, and both shape who buys design and construction here. The office-furniture base built it: Steelcase, MillerKnoll, and Haworth still run major operations alongside Amway, Meijer, SpartanNash, Wolverine Worldwide, and the consumer-health maker Perrigo. Layered on top is the Medical Mile, where Corewell Health, Van Andel Institute, and MSU's College of Human Medicine drive a steady clinical and lab pipeline, including Corewell's planned Butterworth campus expansion. What sets this metro apart is concentrated civic capital: Grand Action 2.0 and the DeVos and Van Andel families steer marquee downtown work like the Acrisure Amphitheater and Amway Stadium. This is a competitive, relationship-bound market where the same owners, developers, and primes recur, and selection runs on reputation, not low bids.

Fort Wayne is a hospital-and-defense town, and that decides who buys design and construction here. The two biggest owners are the rival health systems Parkview Health and Lutheran Health Network, and right behind them sit defense and precision manufacturers in expansion mode: BAE Systems on the Armored Multi-Purpose Vehicle, L3Harris, GM Fort Wayne Assembly, and Fort Wayne Metals. The development pipeline runs through Electric Works, The Eddy, and the airport's Project Gateway. It's a tight design community where Elevatus, MartinRiley, MSKTD, Hoch, and Engineering Resources keep showing up on the same teams. Winning work here means being the known firm those owners and primes already trust, not the low number from a stranger.

Columbus is the corridor's boom market, and the money flows from a handful of named owners with enormous capital programs. Intel's Silicon Heartland campus in New Albany and the Honda-LG battery plant near Jeffersonville are anchoring a wave of supplier, road, and utility work. Ohio State's Wexner Medical Center just opened a $2 billion University Hospital tower, OhioHealth is spending over a billion across Riverside and Grant, and Nationwide Children's is mid-build on a multi-tower program. The $2 billion John Glenn terminal runs under Hensel Phelps as construction manager. Add headquarters owners like Nationwide, AEP, and Bath & Body Works, plus OSU itself. It's a crowded, well-funded field, so the win goes to the firm those owners and their program managers already trust, not the low number from a stranger.

Indianapolis runs on one outsized buyer first: Eli Lilly, whose Indiana capital push now tops $21 billion, including the $4.5 billion Lilly Medicine Foundry at the LEAP Lebanon district, has pulled cleanroom, utility, and process work to firms that already know pharma owners. Around it sits the metro's other anchor demand: IU Health's $4.3 billion downtown hospital consolidation, the Indiana Convention Center and Signia by Hilton expansion, Traction Yards at the old Circle Centre, and IndyGo's Blue Line BRT. This is a deep, competitive market with strong homegrown primes like American Structurepoint, so a stranger underbidding goes nowhere. Work flows to firms the plant engineers, health-system facilities directors, and IEDC and INDOT program managers already trust by name.

Louisville buys design and construction across an unusually broad base, and that shapes the BD game here. Logistics drives capital through UPS Worldport, manufacturing through Ford's Kentucky Truck Plant and GE Appliances Park, and a bourbon building boom flows from Brown-Forman's Old Forester expansion. Health systems are the steadiest owners: UofL Health, Norton Healthcare, and Baptist Health keep tower, clinic, and campus work in motion. Public capital runs deep too, from the billion-dollar-plus SDF Next airport program to MSD, Louisville Water, and KYTC District 5. The catch for outside firms: Louisville is a dense, competitive AEC market with entrenched homegrown players like Luckett & Farley, K. Norman Berry, and CMTA who already own these buyer relationships. Winning here means being known to facilities directors and program managers, not underbidding an incumbent they trust.

Nashville buys design and construction at boomtown speed, and the buyers are concentrated. Healthcare runs the table, with HCA Healthcare's headquarters, Vanderbilt University Medical Center's roughly $500M Link tower, Ascension Saint Thomas, and HCA's TriStar all building. Layer in corporate relocations like Oracle's 70-acre East Bank campus and Amazon at Nashville Yards, the $2.1B new Nissan Stadium, and BNA's $3B New Horizon expansion. It's also a deep AEC town: homegrown primes like Gresham Smith and Smith Seckman Reid headquarter here, and national firms have planted flags. That makes this a crowded, competitive field, not an open one. The same owners, primes, and program managers recur, so winning runs on being known to them, not on underbidding a stranger.

Huntsville runs on federal money, and that decides who buys design and construction here. Redstone Arsenal anchors everything: 72 tenant organizations including NASA's Marshall Space Flight Center, a fast-growing FBI campus, and the incoming U.S. Space Command headquarters. Around it sit the defense primes in Cummings Research Park, the second-largest research park in the country, where Lockheed Martin, Boeing, Blue Origin, Leidos/Dynetics, and SAIC keep building. Add the Huntsville Hospital Health System, one of the largest publicly owned hospital systems in the nation, UAH, Alabama A&M, and the Mazda Toyota plant on the west side. This is a relationship market full of repeat institutional and federal owners, where facilities directors, prime contractors, and the Health Care Authority pick firms they already trust over a low bid from a stranger.

Birmingham is unusual: the biggest buyers of design and construction and the biggest builders both sit downtown. UAB and the UAB Health System anchor everything, with a steady pipeline like the $73M North Pavilion emergency department expansion, the Zeigler research building renovation, and the new UAB Medical West hospital in Bessemer. The corporate base runs deep too: Regions Financial, Protective Life, Vulcan Materials, Encompass Health, EBSCO, and the $330M Coca-Cola Bottling Company UNITED campus. What makes this market its own animal is that Brasfield & Gorrie, Robins & Morton, and Hoar are headquartered here, so the prime relationships you need are local and tightly held. Winning runs on being known to those owners and primes, not on the low number.

Augusta runs on federal and institutional money, and that decides who buys design and construction here. U.S. Army Cyber Command and the Cyber Center of Excellence at Fort Eisenhower, the Georgia Cyber Center downtown, and the Savannah River Site's active plutonium processing build drive a security-cleared, prime-and-sub world where the same players recur. Layer in Augusta University and the Medical College of Georgia, with a state-funded translational research building breaking ground, plus the new Wellstar Columbia County hospital, and you get owners who hire on track record. It's a market with entrenched incumbents like Cranston Engineering and Johnson Laschober, so the work goes to firms the program managers and facilities directors already trust, not the low number from a name they don't know.

Macon's design-and-construction demand is being rewritten in real time by the Macon-Bibb County Industrial Authority, which in 2026 landed ArcelorMittal Building Solutions' North American HQ at the Airport South site and Unified Legacy's $125M aerospace-and-defense fabrication plant on Barnes Ferry Road. Layer on the standing anchors: Robins Air Force Base 16 miles south in Warner Robins, GEICO's largest regional office, Atrium Health Navicent and its 637-bed Medical Center with the Luce Heart Institute, and Mercer University's historic main campus. This is a market where the Authority, plant facilities directors, and hospital and campus owners hand work to firms they already trust. You win here by being on the Authority's shortlist and known to those owners, not by underbidding a stranger on a public letting.

Tallahassee runs on public money, and that decides who buys design and construction here. The state government is the anchor: agency facilities, the Capitol complex, and the Department of Management Services, whose Bureau of Building Construction oversees state buildings. Then come the campuses, Florida State, Florida A&M, and Tallahassee State College, each with its own facilities and construction office, plus the new FSU Health and Tallahassee Memorial academic health center opening in 2026 and the recently finished $265M Doak Campbell rebuild. Local capital flows through one unusual engine: the Blueprint Intergovernmental Agency, the city-county body spending a one-cent surtax on roads, parks, and stormwater. These owners select under Florida's CCNA process, so work goes to firms already on the shortlist and known to procurement. You win by being that name, not by underbidding.

Jacksonville runs on defense, the river, and a downtown that's finally building. Naval Air Station Jacksonville and Naval Station Mayport, with the USACE Jacksonville District, anchor a federal pipeline, while JAXPORT, SSA Atlantic at Blount Island, CSX, and Jacksonville-based Crowley keep maritime and logistics work moving. Healthcare buyers run deep: Mayo Clinic, Baptist Health, UF Health, and Ascension St. Vincent's all build continuously. Add fintech owners FIS, Fidelity National Financial, and Dun & Bradstreet, plus a $6.5 billion downtown pipeline headlined by the $1.4 billion Jaguars Stadium of the Future and Gateway's Pearl Square. It's a sprawling, competitive market where the Haskell, Auld & White, and RS&H tier already owns the relationships. Breaking in means being known to these owners and selection committees, not bidding low against incumbents.

Tampa is one of the corridor's hottest growth markets, and its design and construction buyers split into a few clear camps. Private development drives the skyline: Strategic Property Partners' Water Street Tampa, a roughly $3 billion downtown district, plus Darryl Shaw and Kettler's 50-acre Gasworx in Ybor City. Defense is the other engine, anchored by MacDill Air Force Base, home to CENTCOM and SOCOM, and the contractors orbiting it. Then there's the institutional base: Tampa General Hospital and the USF Health Morsani College of Medicine that anchor the Tampa Medical and Research District. This is a crowded, fast market where national primes and developers run repeat programs. You don't win these by underbidding strangers, you win by being the firm their program managers already trust.
