    We Make Buildings Work. The work behind that is only possible because of the people who keep everything moving, and that's what we're highlighting on this Administrative Professionals Day.Across our offices, our administrative team supports every part of the business. They keep financial processes on track, keep teams organized as priorities shift, and handle the day to day coordination that keeps work moving without things slipping through the cracks.Amie Pierson, Catherine Wauthier, Dawn Schaefer, Erica Peckham, Susan Murray, and Stacey Lively each play a critical role in supporting our teams and keeping operations running smoothly.This year also marks a transition for someone who has been a part of that foundation for a long time. After 10 years with Callidus Engineering, our own Misi McKone has retired. Her contributions to our accounting department and growth have left a lasting mark on the team, and we wish her the best into the future!To say we are grateful for the work they put in will always be an understatement.

    We were on site last week at the Carpenter’s Union Hall Addition in London for a final look at the completed space.The project includes a 5,100 sq. ft. addition with a mezzanine, with new mechanical and electrical systems integrated into the existing building. Rooftop HVAC, duct distribution, gas piping, plumbing, lighting, controls, and fire alarm all needed to connect cleanly with what was already in place and perform as intended.With the addition now complete, the facility has expanded space to support training programs for future carpenters, and It’s always rewarding to see the finished design in use on site. #EngineeringExcellence #LDNont #OntarioConstruction ...
