Subcontractor says unpaid balance forced a shutdown

Mike Owen, president and owner of Adamson Plumbing Contractors, says his company is still owed nearly $4 million for work at the Obama Presidential Center in Chicago. He says the unpaid balance and project fallout pushed him to suspend operations and lay off 25 union workers. He went on record in broadcast and print reports. He described months of attempts to collect that failed before the shutdown decision in late June.

The company worked under the name Marsh-Adamson on the project’s plumbing scope. Reporting states Adamson filed a $1.72 million mechanic’s lien against the property. A mechanic’s lien is a legal tool that helps secure payment for labor and materials supplied to a property. It does not decide the dispute. It preserves the right to collect while the parties fight over what is owed.

Delays, rework, and last-minute demands deepened the losses

Owen says the losses grew beyond the unpaid balance due to delays, rework, and changing demands on site. He pegs the hit at about $3.9 million. He also says Adamson agreed to provide two plumbers for last-minute overnight work in return for a partial payment before the June 19 opening but that the payment did not arrive on time. He says the company then suspended operations on June 25 after the cash crunch became unsustainable.

Construction payment fights often spike at closeout. Large projects rely on layered contracting, change orders, and complex approvals. When change orders stall and communication breaks down, subcontractors face the squeeze first. They must front payroll, materials, and remobilization while they wait for approvals. That structure tilts leverage away from small firms. The Obama Presidential Center dispute follows that well-known pattern, which makes the claims plausible on their face within industry norms.

Other firms report unpaid invoices and strained communication

Multiple outlets report that other trade contractors on the project say they remain unpaid for change orders and added work. Some describe broken communication during crunch time before the opening. One trade publication reported several firms citing unpaid change orders and limited response from project leaders. Broadcast segments also featured subcontractors who say they are owed millions, with some bound by non-disclosure agreements that limit what they can share publicly.

These parallel accounts do not prove Adamson’s exact number. They do show a broader payment dispute environment around the job. When several firms report similar friction at the same milestone, that points to a systemic closeout problem, not a lone outlier. For readers who value fair dealing and a hard day’s work paid in full, that pattern raises red flags that deserve a fast, transparent reconciliation.

What remains disputed, and why it matters

Public records surfaced so far show a mechanic’s lien for $1.72 million, not the full nearly $4 million. No court judgment, arbitration award, or sworn deposition in this record confirms the final amount due. FactCheck.org reports the Obama Foundation says it has no direct contracts with subcontractors and that Lakeside Alliance has primary responsibility for subcontractor payments. That chain-of-contracting detail shapes who owes whom, and where to press a claim.

Common sense says pay the people who did the work, and do it on time. The facts reported so far give Adamson a clear, documented stake: years of work, a public claim, a recorded lien, and layoffs that hurt families. The Foundation’s stance about not contracting directly with subs may be legally sound. But if the owner paid the construction team, and the subs still lack payment, then the construction manager must show its ledger, fast. Sunlight solves this kind of dispute.

What a clean resolution looks like

A fair fix starts with a side-by-side ledger: base contract, approved change orders, pending change orders, pay applications, and retainage. The construction manager should share a dated list of payments made and disputed items. Adamson should share invoices, change-order requests, daily reports, and time-and-materials tickets for the alleged overnight and rework tasks. A short mediation with senior decision makers can close gaps in days, not months. The public deserves that clarity now.
