Gayanga Co. was a Detroit-headquartered, Black-owned heavy civil and demolition contractor founded to create real careers for the people who lived in the neighborhoods we rebuilt. From 2016 to 2026 we grew a 32-home residential demolition contract into the largest Black-owned heavy civil and demolition firm in Michigan — more than $80 million of work, every dollar of it competitively bid. This page is the record of what we built, who we built it with, how we won the work, and what happened at the end.

Gayanga took its name from Gaspar Yanga, who led a colony of escaped enslaved Africans in Mexico during Spanish colonial rule in the 16th and 17th centuries. Yanga instilled a passion for liberty and self-determination in his people, and his community became the first free colony of Africans in North America.
Too many "Black-owned" construction companies are Black in name only.
A Black name on the truck. A Black founder at the press conference. And a company that is white where it counts — who owns the equipment, who runs the crews, who keeps the profit. The neighborhood gets nothing.
Gayanga was named so it could never be that.
Self-determination meant Black ownership that owned the work: its own crews, its own iron, its own estimators, its own decisions. It was never only about tearing buildings down. It was about who got to do the work, who got paid a living wage for it, and who got to say they built something in their own city.
Gayanga Co. was a place where people built their dreams. Our focus was on people. We weren't solely creating jobs — we were creating opportunities.Brian McKinney Sr., Founder & CEO
Detroit was running the largest residential demolition program in the country. Thousands of blighted homes were coming down and the money was real. But very few of the firms doing the work were owned by Detroiters, and very few of the people on the crews came from the neighborhoods being cleared. The Detroit Free Press would document it plainly in 2018: in a majority-Black city, the demolition money was going overwhelmingly to large firms from outside it.
Brian McKinney, a native Detroiter who had spent years in the technology startup industry before coming home, founded Gayanga Co. in 2016 as a certified minority-owned construction engineering firm headquartered in the city. The idea was simple: if Detroit was going to be rebuilt, Detroiters should be the ones getting hired, trained, and paid to do it.
It was not easy to get in. Detroit was the only municipality in Michigan that required its own demolition license, and the board that reviewed a new applicant was made up largely of the established contractors it would be bidding against. The City's prequalification process had already been gamed by firms with no workforce at all, and a new Black-owned company with no track record had to be bonded before it could bid a single group of houses.

Growth came one bid at a time. Gayanga razed 32 homes in the last quarter of 2017, 186 in 2018, and more than 400 a year in 2019 and 2020. City work went from a $500,000 first contract to $17 million in 2021, and annual revenue grew from about $450,000 in 2017 to nearly $18 million in 2024. Bonding capacity grew from $3.5 million to $12 million. And the work grew beyond demolition — into water mains, earthwork, site development, industrial work for Marathon and DTE, and joint ventures on some of the biggest projects in the city, with an in-house engineering and estimating team to win it.

32 homes under the Hardest Hit Fund. Gayanga began hiring from the neighborhoods where it worked.
The first 32 homes were also nearly the last. The federal Hardest Hit Fund money was going overwhelmingly to large non-minority firms, and when Gayanga said so — loudly, publicly, and to the Free Press — the Land Bank's bidding rules changed in ways that shut the company out of the regular bid groups. For the better part of two years Gayanga lived on emergency demolitions, the one-off hazard jobs nobody planned for, and on a water contract it won on its own: sole contractor disconnecting water service lines and pumping out flooded basements for the Detroit Building Authority's Blight Removal Program — more than 700 disconnects and pump-outs under a $2.2 million contract. The work went well enough that the DBA kept Gayanga on when the contract moved to the City in 2020, extended it into 2021, and then awarded the company a new $2.25 million Water Related Services contract that spring. It was Gayanga's first underground utility work, and the crews trained on it became the company's water main and excavation teams. 186 homes demolished.
Gayanga was selected directly by BNA Constructors, the joint venture building the Gordie Howe International Bridge, for clearing, grubbing, and grading of the 160-acre U.S. port-of-entry site; took the five-story Historic Woodland apartment building down in 10 days; and handled demolition, contaminated-soil removal, and ash-basin backfill as a subcontractor to Independence Excavating at DTE's Conners Creek Power Plant — a job DTE later marked with commemorative awards to the project team. 400-plus homes demolished. Brian McKinney named to Crain's 40 Under 40.
After City Council rejected the Mayor's first $250 million blight bond in November 2019, Gayanga's leadership and a coalition of Black contractors stood with Council members at a July 2020 press conference to push a rewritten proposal centered on Detroit jobs and Detroit businesses. Council put Proposal N on the ballot that week, and voters approved it in November 2020 — a $250 million bond to demolish or stabilize 16,000 vacant houses, with a 30 percent set-aside for Detroit small businesses and a 51 percent Detroit-resident hiring target. Mayor Duggan publicly credited Gayanga's CEO for helping get the bond approved. In December 2020 Gayanga worked with City Council and Locals 324 and 1191 on the Construction Project Equalization Credit amendments that gave Detroit-based union contractors a fair shot at the work. The same year Gayanga formed its first joint ventures with Major Cement, a Detroit civil contractor it had been hauling for since 2017: roughly $10 million of Department of Public Works streetscape work on McNichols and Conant, then Grand River and Puritan, Rosa Parks, and the first DWSD water main packages. It was the start of the underground and civil business — and of a partnership that would last the rest of the company's life.
BridgeDetroit's breakdown of Proposal N data showed Gayanga holding six contracts worth about $18.45 million — the most of any contractor in the program. Marathon Petroleum brought Gayanga on as its prime demolition contractor for the Boynton neighborhood property program beside the Detroit refinery — private industrial work that continued through 2025. The Major joint venture — now Major Contracting — added the West Warren and East Warren streetscapes. A three-year DWSD water contract followed. The Workforce Development Program graduated its first cohort.
Gayanga had been building its back office since 2020 — recruiting field and office leaders from Independence Excavating, Homrich, Barton Malow, Detroit Dismantling, and the City itself, and paying to keep them. In 2023 the key pieces landed: the City of Detroit's Deputy CFO came over as CFO, the compliance specialist was hired out of the City's own demolition compliance department, and the safety and environmental compliance manager recruited from Independence had a full year of authority over every site. 70 employees on payroll.
78 employees, $3.3 million in payroll, and a network of Detroit-based trucking, abatement, and concrete subcontractors working alongside Gayanga. Henry Ford Health selected Gayanga as a minority partner on its Destination: Grand campus expansion.
Gayanga and Major Contracting were awarded roughly $43 million of Detroit Water & Sewerage Department water main work for 2025–2027. Together with the Henry Ford Health work, Gayanga entered 2025 with more than $40 million of contracted work on the books for the following three years.
Demolition was the front door. By 2025 Gayanga was a heavy civil contractor: water main replacement, underground utilities, electrical duct banks and pads for electrical contractors, streetscapes, earthwork, and site development, often as the Detroit-based, Black-owned partner that let a larger firm meet the City's inclusion goals with a company that actually self-performed the work. The longest of those partnerships was with Major Contracting, known as Major Cement when Gayanga first hauled backfill for it in 2017. From 2020 on, the two firms bid the City's streetscape program together through individual joint-venture agreements, each one certified by the City as a joint venture: the McNichols streetscape (PW-7004, bid April 2020, the first, with more than 7,000 feet of curb), Conant (PW-7016, 6,000-plus feet), Grand River and Puritan (PW-7017), Rosa Parks (PW-7015), and in 2022 West Warren (PW-7013) and East Warren (PW-7034) — about $10 million of streetscape work in the first year alone and about $25 million of Department of Public Works work in all, with Gayanga's crews on the curb, sidewalk, and pavement removal and its trucks on the hauling. They went on to DPW sidewalk replacement, the DWSD Huber parking lot, and DWSD water main work, and in 2025 formed a standing joint-venture company, Gayanga Major Joint Venture LLC, to pursue larger packages together.
Most demolition contractors Gayanga's size bought their estimating from the outside. Gayanga built it in. LaCresha Turner — an African American civil engineer and Detroit Public Schools graduate with a quarter century in construction — joined after the first award as Vice President of Engineering & Estimating and built the department that took the company from house-by-house demolition bids to water main packages, streetscapes, and industrial site work. Her team priced every DWSD and DPW package the company pursued, ran submittals and value engineering on the joint ventures, and trained a rotating bench of engineering interns from the University of Michigan, Wayne State, and Michigan State, several of whom stayed on as Gayanga engineers. When Gayanga had under $1 million in awards, that department did not exist; by 2022 it was pricing $25 million of work a year.
The City's program was the foundation; the private and industrial work proved the company could operate anywhere. In 2019 Independence Excavating brought Gayanga on as a subcontractor for DTE's Conners Creek Power Plant demolition — the excavation, hauling, and disposal of 20,000 cubic yards of contaminated soil, backfill of the plant's ash basin, and demolition of the Edison Boat Club, more than 3,500 crew hours on a live industrial site. It put a Black-owned Detroit contractor on a power plant demolition of that scale, doing the heavy work. Independence's project manager closed the job with a note: "A great project, with great team members. Looking forward to working with you on the next one." Within the year Independence had Gayanga hauling processed steel on its own out-of-state work. In 2022 Marathon Petroleum, after putting the company through its safety and drug-testing prequalification, hired Gayanga directly as its demolition contractor for the Boynton neighborhood property program beside the Detroit refinery — abatement, demolition, and site restoration on Liebold, Patricia, and Bassett — and kept issuing work orders through 2025.

After a series of DPW streetscape and road joint ventures, the partnership was awarded two DWSD water main replacement contracts, WS-744 and WS-745, covering Detroit neighborhoods through 2027. Gayanga was the joint-venture partner on both, with its own crews in the trench and responsibility for the trucking.

Selected as a minority partner on the multibillion-dollar Henry Ford Health expansion in New Center — utilities, excavation, and concrete work on one of the largest health-care builds in Michigan.

Site clearing, grubbing, grading, erosion control, sediment ponds, and berm construction for what became one of the largest ports of entry in North America.
Between 2017 and 2025 Gayanga demolished approximately 2,500 structures in Detroit and won more than $80 million in contracts across demolition, water services, underground utilities, streetscapes, site work, and joint ventures. Every City contract among them was won through a competitive bid.

A century-old, five-story, 36,000-square-foot, 44-unit apartment building — long a neighborhood hazard — taken down with a high-reach excavator and union crews in 10 days on a contract that allowed 120, with the debris hauled by Gayanga's own trucks. Dust suppression and air monitoring ran throughout; the City's demolition appeals board later reviewed the job and cleared Gayanga.

Residential demolition, environmental abatement management, backfill, grading, and hauling across every district of the city — from the Hardest Hit Fund through Proposal N.

Subcontractor to Independence Excavating on the plant demolition: excavation, hauling, and Class II landfill disposal of 20,000 cubic yards of contaminated soil, ash-basin backfill, and demolition of the Edison Boat Club.

Board-up, asbestos survey and abatement, demolition, and backfill of refinery-purchased homes in the Boynton neighborhood, performed directly for Marathon under its own safety program — nine job packages by 2025.
A Black-owned contractor doing the most work in the program knew it would be watched more closely than anyone else. So Gayanga built a compliance operation that no other demolition contractor its size carried — and paid for it entirely out of City contract margins.
Gayanga did it by going to the people who already knew the City's rules and paying them more to enforce those rules inside the company. Where the City required one designated project manager per contract, Gayanga assigned a full team, so that every stage of every site had overlapping oversight — and every one of those people had been recruited from the City, the Land Bank, or the largest union demolition firms in the region.
Superintendents and foremen were paid above union scale. The finance, operations, and safety leads — including dedicated, full-time safety professionals — were paid well into six figures. Even the support roles were paid to keep the paperwork perfect, and every one of them had the autonomy to do their jobs. All of it was dedicated to City of Detroit work. That level of staffing and compensation was not excessive. It was necessary. It worked. From 2016 until the September 2025 suspension, every complaint or inquiry raised against Gayanga was examined and found unsubstantiated. The most thorough test was the first investigation by the City of Detroit Office of Inspector General (the City's OIG). A company doing this much work draws complaints, and this one began with an allegation — later found unsubstantiated — about an individual's handling of backfill load tickets, not about the company's process. Gayanga still had to answer it, at its own expense and on its own time. It turned over everything: where every load of dirt came from, the City's approval of each source, and the load tickets for every site. The City of Detroit Office of Inspector General then brought Gayanga's field and office staff in one at a time for individual interviews — the superintendents, foremen, and operators who actually ran the backfill, and the office staff who processed the tickets — with no company leadership in the room. Every one of them described the same process. On September 27, 2023, the OIG closed the case, reporting that it did not find evidence to substantiate the allegations. Gayanga was cleared — and responded by moving its backfill to City-listed public sources and City-approved suppliers anyway. That is what a real investigation looked like: everyone was called in, everything was produced, and the conclusion followed the evidence. Two years later, on the same subject, the same office did none of it — no interviews of the crews who did the work, no request for the tickets, no call to the supplier it named — before publishing its findings. To Gayanga, the difference was the whole story. The 2023 investigation was an inquiry. The 2025 one felt, from the first day, like an investigation with its conclusion already written.
It was not the first time Gayanga had been tested in public and cleared in the record. In 2019, after the Historic Woodland apartment building came down, a local media personality ran a series claiming Gayanga had released asbestos into the neighborhood. The facts were different. The building had been ordered demolished as unsafe to enter, with asbestos left in place under the state's own rules for such structures; Gayanga ran a Dust Boss misting system throughout the takedown and had an environmental firm perform air monitoring during the demolition. The state's review came down to a notification form — a box that should have been updated, and an ordered-demolition letter the City's building authority had not attached. On September 17, 2019, the City's demolition appeals board reviewed the air-monitoring data and dust-suppression records and cleared Gayanga, finding no evidence of improper demolition work. Gayanga's response was to hire an in-house industrial hygienist so that every environmental notification and every site would have a specialist on it from then on.
Every time someone came for Gayanga's name — a media personality, a former employee, an inspector general — the record was checked. And every time the record was checked, it held.
A local media personality ran a series claiming Gayanga had released asbestos into a neighborhood at 31 Woodland.
Dust suppression ran throughout; an environmental firm monitored the air. The state's review came down to a notification form — a box that should have been updated. On September 17, 2019, the City's demolition appeals board reviewed the data and cleared Gayanga.
An allegation, later found unsubstantiated, about one individual's handling of backfill load tickets — a claim about a person, not the company.
Gayanga produced every ticket and every source approval. The OIG interviewed the field and office staff one at a time. On September 27, 2023, it closed the case: no evidence to substantiate the allegations.
The OIG announced that Gayanga had filled its sites with contaminated dirt from a Northland Mall redevelopment.
The Mayor's own review found otherwise. "We reported to the Inspector General that the idea that in the first half of 2024 large amounts of dirt came from other locations did not appear to be true." — Mayor Mike Duggan, December 22, 2025. Watch the briefing.
Much has been said about how Gayanga got its contracts. This is how it actually worked. Every demolition group in Detroit's program — Hardest Hit Fund, City General Fund, Proposal N — was put out by the City's Office of Contracting and Procurement as a sealed, competitive bid. The lowest responsive bidder won. Gayanga bid on nearly all of them, lost far more than it won, and won its share. One more point of fact: under Detroit's charter, City Council does not select contractors. Awards were made by the Mayor's administration — the Office of Contracting and Procurement, the Construction & Demolition Department, and the departments Gayanga worked for — with Council voting only on approval of the resulting contracts. The idea that a Council member could hand Gayanga a contract is not how the City works.
The City's award terms were the same for everyone: if "the lowest bidder does not receive final contract approval, the City of Detroit reserves the right to award to the next lowest bidder." Prices, not relationships, decided the work.
June 2023: the City released Proposal N Groups Q7, Q8, Q9, and Q10 together. Gayanga bid all four and won one — Q10. The other three went to lower bidders.
Summer 2024: of eighteen emergency demolition bids the City opened, Gayanga won three. Other Detroit contractors won six, seven, and three.
Every contract above the threshold went to City Council in public session for approval, with the bid tabulation attached — roughly $59 million of Gayanga awards between 2019 and 2022 alone, according to the Free Press.
Detroit's ordinance gave certified Detroit-headquartered and Detroit-based businesses a small bid equalization credit — a few percentage points — to offset the higher cost of hiring residents and paying union scale. Gayanga earned that credit the hard way: by actually being headquartered in the city, actually employing Detroiters, and actually paying prevailing wages with fringe benefits, all of which the City verified.
Proposal N went further. The $250 million bond that Gayanga's leadership helped campaign for included a 30 percent set-aside — about $75 million — for Detroit small businesses and a 51 percent Detroit-resident hiring requirement. That was the program Gayanga competed in, alongside more than twenty other contractors, most of them Detroit-based.
Gayanga did not only bid for itself. The company's leadership pushed the City to enforce its own prequalification rules after firms with no employees were prequalified and won bids over legitimately qualified contractors. Gayanga hired workers who had been paid in cash by non-union firms and put them on union payroll. It advocated, in writing and in public, for smaller Black contractors who struggled to get access to the program, and it brought them on as subcontractors, truckers, and abatement crews when it won.
No contractor in the demolition program created more living-wage jobs for Black and brown residents in the city of Detroit.Gayanga statement, October 2025
Giving back was not a program. It was the point.
1,000 mealsWith the City's Parks & Recreation Department and FEED Detroit, we served Thanksgiving meals at four recreation centers across the city — Adams Butzel, Farwell, Kemeny, and Joseph Walker Williams — and packed and delivered more the next day.
In the roomAt Randolph Career and Technical Center, Brian McKinney talked with Detroiters getting into the trades about what a union demolition career looked like and how to get one. It was a constant: career fairs, high schools, recreation centers, community meetings, the first-week CDL class at Wayne County Community College's Eastern Campus, hiring days at the Northwest Activities Center — Gayanga showed up, told people the jobs existed, and made sure the people telling them looked like them. That included 1,500 incoming freshmen from 22 Detroit public high schools at the Find Your Future fair and 750 more young people at United Way's Summer Career Connections Fair. And when Brian saw women in that CDL class, he told them one of Gayanga's best drivers was a woman — and brought Whitney in to tell them herself.
Side by sideFor years the relationship ran both ways. When the City needed a contractor at a community meeting, a neighborhood outreach event, a press conference, or a career fair, Gayanga went. And when Gayanga celebrated, the City came: at the company's fifth-anniversary dinner the guests included Conrad Mallett, then the City of Detroit's Deputy Mayor and now its Corporation Counsel, who joined the toast. Gayanga had reached the point where the City did not just award it work — it showed up for it.
For nearly a decade, the public record on Gayanga was a record of a company doing what it said it would do. It is still there for anyone who looks.
On September 11, 2025, the City of Detroit Office of Inspector General (the City's own OIG — not a state or federal office) publicly suspended Gayanga Co. and its founder over backfill dirt at demolition sites, without first contacting the supplier it accused us of misrepresenting. The suspension expired on March 11, 2026, at the 180-day limit set by City ordinance, with no findings against the company. By then the City had canceled every one of Gayanga's contracts, and a company built over a decade was gone. The facts below are drawn from public statements, public meetings, and the complaint Gayanga filed in Wayne County Circuit Court.
A prior inquiry into Gayanga's backfill by the City's OIG, under Detroit Inspector General Ellen Ha, was not substantiated. Gayanga was cleared and, on its own initiative, moved all backfill to the City's public sources.
The City raised Gayanga's required pace from 10–12 to 16–18 demolitions a week — and the pressure came from the top. On July 24, 2024, the Mayor's office wrote to Gayanga that "Mayor Duggan has asked to meet with you" that week, together with the City's Group Executive for Construction and Demolition and a second senior City executive, "to discuss demolition production of his current contracts." The meeting was held in the Mayor's office the following Tuesday. Gayanga had a City-owned, City-approved source of its own at Far West / Rouge Park. It chose to move off it anyway — to the City's public source list and City-recommended brokers and certified suppliers — because after the 2023 investigation the company was under constant scrutiny and believed the public list would give it more protection, not less. It bought material where the City told every contractor to buy it, to keep the City's schedule. Every load was documented, and the City's own liaisons inspected the sites.
The Construction & Demolition Department pulled Gayanga sites at random and audited the load tickets and compliance forms "for completeness and consistency." Its one question was a truck number typed as "19" instead of "198." Eight months later the same department's testing would be the basis for a public suspension.
Following the City's public source list, Gayanga used Iron Horse of Michigan — approved by the City in 2023 through AKT Peerless and a native pit of the kind the Mayor called "the gold standard for backfill" — at dozens of properties. Three other contractors — SC Environmental, Adamo, and Salenbien — used the same source at hundreds more.
The OIG suspended Gayanga and Brian McKinney, alleging the dirt came from a Northland Mall redevelopment and that "33 of 41" tested sites failed, and referred the matter to the Detroit Police Department. Before publishing, the OIG had contacted one supplier — Ashley Land Development, which confirmed Gayanga's loads. It had not contacted Iron Horse, the source it accused Gayanga of misrepresenting; Major Contracting, which hauled most of Gayanga's material; or any other carrier. It had not interviewed Gayanga. The OIG has never told Gayanga who made the 2025 allegations or what they were based on. Whatever they were, they were published before anyone checked them against the load tickets, the City's own liaison inspections, or the supplier.
After Gayanga named its supplier publicly, the City tested other sites, found the same contamination, and suspended Iron Horse as a program supplier.
The City's Inspector General told Council that Gayanga had "filled roughly 2,400 residential sites across the city." Gayanga's field work stopped. Payroll for dozens of Detroiters stopped with it.
Delivering the City's Final Blight Removal Report in his last week in office, Mayor Mike Duggan disclosed that the OIG's original tip — that Gayanga had filled "all of their holes" with Northland Mall material in early 2024 — was checked against the supplier's own records, and that Ashley confirmed 309 of the 323 sites in question. "The report was inaccurate," the Mayor said. He also disclosed that Iron Horse had supplied four contractors at 424 sites, only 87 of them Gayanga's; that "the great majority" of Iron Horse sites belonged to other contractors; and that the City had "no evidence to believe that the contractors knew."
After 90 days and three 30-day extensions, the suspension lapsed at the 180-day limit in the City's debarment ordinance. No investigation — by the OIG, the Detroit Police Department, or anyone else — has resulted in a finding of wrongdoing by Brian McKinney or anyone at Gayanga Co. But the City had canceled roughly $34 million of Gayanga's Proposal N contracts and cut off its share of the $43 million DWSD joint venture. There was nothing left to return to.
Gayanga Co. announced it had closed its doors and filed a defamation lawsuit against the City of Detroit Office of Inspector General in Wayne County Circuit Court (Case No. 26-007722-CZ), seeking $100 million, so the full record could be examined in open court.
The City's response to the lawsuit was a motion to dismiss on governmental immunity — an argument that the City's Inspector General cannot be sued for what it said, not an argument that what it said was true. Gayanga filed its opposition on August 7, 2026. The motion is pending.
The theory behind the suspension is that Gayanga bought cheap contaminated fill to save money. The record shows the opposite. Through its joint-venture partner's DWSD project at Far West Detroit / Rouge Park at 21800 West Warren — a City-owned site whose material was reviewed by AKT Peerless and, after an initial denial, approved as a public source on resubmission by the City's Group Executive for Construction and Demolition — Gayanga had access to clean, City-approved backfill at no cost — and the material was trucked to its sites at no cost as well. Free dirt, freely delivered. There was no financial reason to put anything else in a hole, and no incentive to try.
As the City's pace climbed, Gayanga went looking for more clean dirt the hard way. From November 2024 to April 2025 it paid for months of independent retesting of Waste Management's Woodland Meadows site — some 900,000 tons of native soil excavated from a former golf course — through four separate laboratories and consultants, with Waste Management sharing the cost, to get it approved as a new public source for the whole program. The City's consultant declined the submittal in April 2025. A contractor trying to sneak bad dirt into Detroit does not spend six months and its own money trying to get good dirt approved.
It is alleged Gayanga used contaminated dirt from a Northland Mall redevelopment in Southfield, Michigan to backfill residential properties in the City of Detroit.
Test results showed that the dirt located at 33 of the 41 (over 80%) properties tested thus far failed to meet the state's residential standards.
The expiration of the interim suspension is strictly the result of time limits imposed by the Debarment Ordinance and should not be interpreted as a finding or indication that Gayanga Co., LLC or Mr. McKinney has been cleared of wrongdoing.
The first report we got was from the Office of the Inspector General, who said that they had a tip that in the first six months of 2024, Gayanga wasn't actually using approved sources. They were filling all of their holes with contamination from the Northland Mall. Now the tickets showed that the dirt came from Ashley, a native sand and gravel pit … We went out to Ashley and said to Ashley, did they get the dirt from you? And Ashley said in 309 of the 323 cases, they did get the dirt from us. And so, the report was inaccurate.
We reported to the Inspector General that the idea that in the first half of 2024 large amounts of dirt came from other locations did not appear to be true.
"We reported to the Inspector General that the idea that in the first half of 2024 large amounts of dirt came from other locations did not appear to be true."
None of this is exotic. It is what the same office did in 2023, and what Gayanga's complaint and its response to the City's immunity motion lay out step by step.
| An investigator normally | The City of Detroit Inspector General, 2025 |
|---|---|
| Interviews the accused before accusing them. | Never interviewed Gayanga's leadership or the crews who ran the backfill before publishing. Its own office had done exactly that in 2023. |
| Verifies the tip against the sources named on the records. | Checked one source — Ashley, which confirmed 309 of 323 — then stopped. Never called Iron Horse, the joint-venture partner that hauled most of the material, or a single carrier. |
| Tests the allegation against the documentation on file. | Published before checking the tip against the load tickets or the City's own liaison inspections, and later described the program as "self reporting … no independent source." |
| Counts everything it knows. | Announced 41 sites. Left out the 323 the City had already checked — and put four of those already-checked sites on the "failed" list. |
| Corrects the record when the facts change. | After the Mayor said on December 22, 2025 that the theory "did not appear to be true," the OIG repeated "33 of 41 (over 80%)" on March 19, 2026, without updating a number. |
| Finishes within the time the law allows, or says why it could not. | Let the 180-day suspension run out with no findings, then said the expiration should not be read as clearing anyone. |
| Treats everyone in the same position the same way. | Four contractors used the same City-approved source with the same results. One was named, suspended, and stripped of its contracts. |
| Refers to the police after it investigates — not instead of investigating. | The suspension came September 11. By the Mayor's account the police were brought in September 17, and the OIG's own investigation was still "ongoing" six months later. |
The OIG's "33 of 41" was the whole public case. The list of those 33 properties is attached to Gayanga's complaint, and it breaks down like this.

were backfilled between January and June 2024 from the Ashley pit — the exact period the City had already checked with the supplier, found 309 of 323 loads confirmed, and reported to the OIG "did not appear to be true." They are on the OIG's own list: 3946 Lemay (backfilled January 5, 2024), 3526 Beatrice (February 12, 2024), 4563 Belvidere (April 4, 2024), and 6760 Brimson (June 4, 2024).
was backfilled in 2018, six years before the tip, under a different program and a different set of rules.
Here is the arithmetic, using only the City's own numbers. By the Mayor's account, the City checked 323 first-half-2024 sites with the supplier before the suspension: 309 were confirmed, and of the 14 that were not, 12 tested elevated and 2 did not — 311 clean. The OIG had that information. It announced the 41 and left out the 323. Put the two lists together, counting the four first-half-2024 properties that appear on both only once, and 360 sites had been checked. The OIG's 33 against 360 is about 9 percent, not 80. Even adding every other site the City itself said tested elevated — the eight of its twelve that are not already among the 33 — the total is 41 of 360, about 11 percent. Either way, roughly nine out of ten sites were clean. That is not a number that justifies a public suspension, and it is nothing like the number the public was given.
Why did the announcement leave out the 309 sites the City had already confirmed?
So the question a reader is entitled to ask is this: if the City had told its own Inspector General that the first half of 2024 checked out, why were four properties from that period on the list? If the source at fifteen of the sites was one the City had approved, was using with four contractors, and would soon suspend itself, why was one contractor named? And why did the announcement leave out the 309 loads that were confirmed?
Gayanga's answer, in its complaint, is that the OIG was looking for a contractor to blame, not for the truth. Its office never interviewed Gayanga's leadership or the crews who ran the backfill before suspending the company. It never called the supplier it accused Gayanga of misrepresenting. It relied, by its own later statement, on the City's Construction & Demolition Department to do the testing — the same department that approved every source the material came from and the only body with authority to do so. It referred the matter to the police only after it had already made the accusation; by the Mayor's own account, the police were brought in on September 17, six days after the suspension, and after Gayanga had been cleared on the first-half-2024 allegation. None of the other three contractors using the same source had their staff questioned, their tickets pulled, or their contracts touched.
In Gayanga's view, that is the tie that holds the whole thing together. Every source in question — Far West Detroit, Ashley, Iron Horse — was approved by the City's Construction & Demolition Department and its consultant. That department set the pace, ran the field liaisons who inspected the sites, published the source list, and then conducted the testing the OIG relied on. A finding that the approved sources were bad is a finding about the department that approved them. A finding that one contractor cheated is not. Gayanga believes the second story was told because the first one could not be. It was not the first time, either: in Gayanga's experience, the official who as a deputy director of the Building Authority oversaw the 2018 rule changes that pushed Gayanga out of the regular bid groups went on to run the department that approved these sources — a consistent theme across seven years, and a department with every reason not to want residents asking who picked the dirt.
That reform is an admission of what was wrong before. Gayanga is asking who was responsible for it.
Gayanga does not say this with bitterness. It says it because the public record says it, and because the people who lost their jobs deserve to know why.
Iron Horse of Michigan's pit on Childs Lake Road in Milford was approved as a public backfill source by the City's environmental consultant, AKT Peerless, on August 3, 2023, and was on the public source list the City's Construction & Demolition Department circulated to every demolition contractor in 2024. The Mayor himself called a native pit like Iron Horse "the gold standard for backfill." What the City did not say is that Iron Horse's owner, Rodney Burrell, had pleaded guilty in 2010, in the federal corruption case that ended the Kilpatrick administration, to submitting an inflated bid to help a Kilpatrick associate win a City contract — a fact BridgeDetroit reported after the suspension. The department that scrutinized every load ticket Gayanga filed put that supplier on its public source list. Gayanga used it, on the City's list, at dozens of properties between March and July 2025 — 87 by the City's own count. So did SC Environmental, Adamo, and Salenbien, at hundreds more.
On March 9, 2026, at City Council's Public Health & Safety committee, a City Construction & Demolition official told Council members that a contaminated site at 5558 Ivanhoe was "the Gayanga dirty-dirt property." The State of Michigan's public demolition data for that address lists SC Environmental as the demolition contractor — and the City had already paid $37,298.40 to remediate it.
In June 2026 the Free Press reported the highest cleanup bill yet in the program: nearly $93,000 to remove and replace the fill at 4551 25th Street. That site, too, was SC Environmental's, not Gayanga's.
Gayanga used the same City-approved sources the Construction & Demolition Department put on its public list, yet we alone were accused of sourcing fill from somewhere we didn't — and it was only after we identified our supplier and handed over the records that the City tested other sites and found the same elevated contamination elsewhere, including one cleanup now costing roughly $92,880. Had the City's Inspector General investigated before making public accusations against Gayanga, this source would have been stopped sooner and far fewer holes would have been filled with dirt that could have been contaminated.Gayanga Co. statement to the Detroit Free Press, June 25, 2026
While the City described itself as cleaning up the contamination — and its Law Department told Council in May 2026 that cost recovery "is being pursued" — against Gayanga — it was hiring the contractor whose sites had failed to do the cleanup. At 3314 Edsel the City paid SC Environmental $19,382 to demolish the house and fill the hole, then $32,795.16 to dig out and replace its own backfill. It did the same at 1230 Patricia, 8392 Gartner, and 8087 Vanderbilt. At five more SC Environmental sites it paid other contractors to do the remediation. And, as Gayanga's complaint states, SC Environmental "later performed the majority of backfill replacement work on Gayanga's sites using the same Iron Horse sourced materials."
By July 2026 the City had excavated more than 100 sites at an average of roughly $34,000 to $36,000 each, with 450 more to go and a total cost estimate approaching $27 million — more than triple the $8 million the Mayor forecast in December. Gayanga, suspended and stripped of its contracts, was the one contractor not working.

Every address in the first nine rows was demolished and backfilled by SC Environmental, not Gayanga — each one confirmed in the State of Michigan's public EGLE asbestos-notification records. The City paid SC Environmental itself $143,041.67 to redo its own work at four of them (highlighted), and paid other contractors $234,828 to fix the other five — $377,869.67 in all for one contractor's work, a contractor that was never publicly named, never lost a contract, and was then hired to do the bulk of the backfill replacement on Gayanga's sites. The last row is the City's own admitted mistake: its field team "incorrectly marked off/fenced off the wrong address," SC Environmental was paid $27,280.64 to dig out and refill 8982 McClellan, and the contaminated property next door, 8990 McClellan, "will need to be rebid." The requestor of record on that form was the Construction & Demolition Department's director.
Gayanga has never asked for special treatment. It has asked for the treatment the City gave everyone else in the same program. Here is how that treatment compared.
In 2019 two former employees of the Adamo Group — one of the largest demolition contractors in the program — pleaded guilty in federal court to bribery and bid-rigging in Detroit's demolition program, including sharing another contractor's price sheets. The company said it had not known. It was not suspended. Its contracts were not canceled. No public OIG investigation of the company followed, and it was still working in the program, using the same Iron Horse source, in 2025.
Gayanga: no employee charged, no finding of wrongdoing, company and founder suspended by name, every contract canceled.
In June 2022 the OIG suspended Inner City Contracting, a Detroit-based demolition contractor with nearly $10 million in program contracts. In September 2022 the OIG rescinded the suspension and declared the company "eligible to resume all work." Its contracts had waited for it.
In November 2025 the OIG told City Council that an interim suspension means "all contracts are canceled … you can't" work. That is what happened to Gayanga. It is not what had happened to Inner City Contracting three years earlier.
The Mayor promised the City would remove bad fill first and "go after" those responsible for the cost. Instead the City paid SC Environmental — a contractor whose own sites had failed — $143,041.67 to replace its own backfill at four of its own addresses — Edsel, Patricia, Gartner, and Vanderbilt — paid other contractors $234,828 to fix five more of its sites, paid it another $27,280.64 to remediate the wrong address — 8982 McClellan, when the contaminated property was 8990 McClellan — and then hired it to do the bulk of the backfill replacement on Gayanga's sites. Adamo and Salenbien, whose sites received the same Iron Horse material, kept working. So did Gayanga's own joint-venture partner — the firm that hauled most of Gayanga's material and supplied it on shared work like the West Warren streetscape. It was never questioned, never publicly named, and never lost a contract.
Gayanga, whose sites received the same material from the same City-approved source, was the only one of the four not working — and the only one named.
The suspension was announced to the press on September 11, 2025 — eight weeks before Detroit's mayoral election, with the founder's name in the headline and, to Gayanga's knowledge, before anyone from the company had been asked a question. If the OIG believed individuals had done something wrong, it never told the company who, or what. It suspended the company.
Gayanga believes the timing and the target were not accidents. Readers can draw their own conclusions from the record above.
By the City's own count, Iron Horse material went to 424 demolition sites across four contractors. Eighty-seven were Gayanga's. The OIG led with "33 of 41" and never corrected it, never mentioned the 309 of 323 sites its own tip got wrong, and never named the other three contractors — SC Environmental, Adamo, and Salenbien — who kept working, and were then paid to clean up. The questions Gayanga has asked the court to answer are simple ones: why the selective narrative, and who it was meant to protect.
Gayanga was built with a purpose — to create real opportunity for Black Detroiters in an industry where access has historically been limited. For nearly a decade we worked to open doors, build careers, and prove that a Black-owned firm can compete and lead at the highest level. We bid for our work, competed fairly, and advocated for smaller Black contractors who struggled to get access to opportunities in the City. When Gayanga closed, no one stepped in to fill the void. The union-scale jobs for Detroiters from these neighborhoods did not move to another company. They simply went away.
What happened over the past year does not just impact me or this company. It sends a chilling message to the next generation of Black contractors and workers trying to break into this industry, and it left the smaller contractors, truckers, and partners who depended on this work dealing with the fallout. That is why we filed suit: so the truth can be told — not just for Gayanga, but for every small, community-based business striving for a fair shot in Detroit.
This is bigger than Gayanga. It is about what kind of environment we are creating for Black entrepreneurs and skilled workers in Detroit, and whether opportunity in this industry will truly remain open.
While this chapter closed painfully, we remain proud of what Gayanga stood for, proud of the opportunities we created, and confident the truth will finally be told.
