Sometimes it feels like road construction in Toronto is non-stop, and if the city's head of construction gets his way, it soon will be for some of Toronto's major projects.

Mike D'Andrea, executive director of engineering and construction services for the city, is proposing 24/7 work hours at 7 sites across the city, and extended hours on 29 other projects. Currently, Toronto has 85 ongoing projects, and if approved, more than 40 per cent of road work would extend past the current 7 p.m. deadline.

"At the end of the day we want to get in and out as quickly as possible," D'Andrea told Metro Morning Thursday.

"We have 270 projects planned across the city. We're spending $550 million in renewing our aging infrastructure."

Most of the proposed 24/7 work would be for major intersection work, such as Toronto Transit Commission track work at College and Bathurst Streets and College Street and Lansdowne Avenue.

D'Andrea says the change could reduce costs because contractors wouldn't experience the delays of setting up and shutting down the site each day.

But he said he understands why the prospect of constant construction might not be appealing.

"We are not intending in anyway to look at jackhammering through the night at those intersections," D'Andrea assured host Matt Galloway.

"We get enough complaints as it is."

The overnight work would mean a lot of lighting, traffic controls and some noise from the beeping of heaving vehicles backing up, D'Andrea added.

Currently, construction runs from 7 a.m. till 7 p.m. in Toronto.

The two water mains that are being replaced are about 120 years old and D'Andrea says the project is an example of the city's attempts to coordinate different divisions, water and transportation, in order to get in and out quickly.

"It's a delicate balancing act," D'Andrea said. "We're not a popular crew in the summer."

D'Andrea's report will be considered by the city's works committee on Monday.
