The City of Saskatoon has widened its court battle over delays with the Circle Drive South Project. It has launched a statement of claim against the engineering firm Stantec.

Construction on the project, which included a bridge, five interchanges and a stretch of highway began in 2010 and opened in 2013, nearly a year late.

Stantec managed the city's contract with general contractor Graham Flatiron. The city and Graham are in arbitration over a $19 million dispute about the project.

Now the city alleges Stantec failed to review various designs on time and failed to manage the project with the standards of care and diligence normally practiced by professional engineering firms.
