Obama Center Subcontractor Shuts Down Amid $4M Payment Fight, 25 Jobs Cut

A Chicago-area plumbing contractor (Adamson Plumbing/Marsh-Adamson) shut down and laid off about 25 workers after a nearly $4 million payment dispute tied to work on the Obama Presidential Center, filing a $1.72 million mechanic's lien and claiming about $3.9 million in overall losses; Lakeside Alliance and the Obama Foundation say payment disputes are being resolved as the project closes, but the financial strain underscores broader concerns about subcontractor payments on the project.
