Callidus Engineering is responsive during projects, and are able to make adjustments quickly, which allows construction to keep moving forward to meet tight timelines. Callidus also displays top of class technical knowledge in the services and solutions they provide.

I started working with Callidus almost five years ago when we hired them as the lead M+E consultant on our new head office in Guelph in 2011.

Callidus was very accessible throughout the duration of the project. They were cost-sensitive, fair on pricing and they truly cared about the success of the project.

We were so impressed by Callidus’ services that we hired them again in 2013 as the M+E consultant on a 600 unit, 5 phase, 12 year high rise project. To this day our first impression of Callidus continues to hold true.

Anytime I need an M+E consultant for a project, Derek is my first call, and I continue to refer both Derek and Matthew to anyone seeking an M+E consultant on their projects.

The team at Callidus Engineering were both responsive and supportive of all those working to complete the project. Not only were their designs effective and balanced but they were also mindful of economics, system efficiencies and practical construction methods.

Callidus Engineering delivers quality work, reliable service and consistent communication through all phases of our projects together. On top of that, they build strong relationships with clients and other consultants on a team. We appreciate how Callidus can find efficient ways to both prevent and solve problems.

I’ve worked with Callidus Engineering for over 10 years on a number of different commercial and residential projects. Not only do they provide and meet realistic timelines, but they are also very friendly and personable. I value the fact that Callidus staff are up-to-date with the Ontario Building Code and industry standards and are open to discussing resolutions to on site issues.
