Transystems Corporation contracts FAQ

- The largest single award on file is $49,995,000, described by the city as "PROFESSIONAL QUALITY CONTROL AND QUALITY ASSURANCE CONSTRUCTION INSPECTION ENGINEERING SERVICES (QA/QC)", approved Sep 1, 2021, through Chicago Department Of Transportation.
- Why can a contract amount be negative?
- The city records revisions and de-obligations as separate rows with negative award amounts. That means a vendor total is the net of original awards plus every later adjustment, not a running tally of payments. Awarded dollars are also not the same as dollars spent — a contract can be awarded and only partly drawn down.
