The mayor of Quebec City said efforts to avoid cost overruns on public works contracts have been successful.

The city commissioned a study to look at all of its contracts over the last four years.

The results show that of the nearly $700 million awarded by the municipal government in public works contracts, less than one per cent  — $2 million — resulted in overspending.

Quebec City Mayor Régis Labeaume said he is proud of his administration and hopes all the hard work will help restore people's faith in how municipalities control their spending.

He said the hiring of 40 city engineers four years ago has helped keep tabs on the city's spending.

Daniel Lessard , head of Quebec City's engineering department, said its approach to limiting budget overspending is unique in the province.

He said that every time there is a modification to a job site budget, a city engineer is present to intervene and help keep extra expenses at a minimum.
