Sinanian Development, based in Tarzana, has obtained contracts to construct a library and classrooms at L.A. City College and a family and consumer studies center at Mission College, among other projects.
In 2008, as the trustees were considering another contract bid from the company, they directed district officials to look into complaints about Sinanian's work, including its failure to meet deadlines, records show.
The company pledged to meet district performance standards and was awarded the contract, for which it submitted the lowest bid, according to minutes of trustee meetings.
About this time, Sinanian pumped more than $75,000 into one of the bond drives.
Trustee Georgia Mercer, one of those who expressed concerns about Sinanian's performance, said in an e-mail that the company's co-president, Sinan Sinanian, "assured us that his company was committed to improving." The firm has since "performed in a very adequate manner," Mercer said.
