    Heat pumps are installed throughout one tower, the central hydronic system is circulating, and the make-up air unit and fluid cooler have completed start-up. The emergency generator has also been load tested, with integrated systems testing completed in June. These milestones were captured during our latest field review of this two-building, 322-unit residential development in London. Our mechanical and electrical scope includes HVAC, plumbing, fire protection, power distribution, emergency power, lighting, fire alarm, communications and access control. With one tower nearing completion and work advancing through the second, the project is showing the level of coordination required to bring complex building systems from design through construction and into operation. #EngineeringExcellence #LDNOnt #LifeSafety ...

    With eighth-floor precast set to begin, the building systems below are already moving quickly to keep pace. Sanitary and storm risers are advancing upward, domestic water and hydronic piping are progressing through the building, and underground ductwork and make-up air risers are taking shape alongside the structure. Our team was recently back on site at Tricar’s new 18-storey apartment development in London, where the mechanical and electrical systems we designed are moving deeper into construction. The development includes 145 residential suites and four levels of parking, supported by a central boiler and chiller plant, suite fan coil systems, fire protection and standpipe systems, emergency power, fire alarm, lighting, power distribution and communications infrastructure. Our latest visit offered a good look at that coordination becoming physical. The chiller is now on site, standpipe risers have reached the upper levels, and electrical, lighting and fire alarm rough-ins are continuing through the parking levels, corridors and suites. There is still plenty of construction ahead, but seeing a project of this scale rise floor by floor is a strong reminder of how much engineering has to come together for important projects like this to succeed. #EngineeringExcellence #LDNOnt #OntarioConstruction ...

    The truth was out there, and last month our Kingston team went looking for it through Improbable Escapes’ Kingston Conspiracy.Downtown Kingston became the setting for an extraterrestrial mystery as some of our Kingston team moved from landmark to landmark, decoding clues, comparing theories and putting their collective problem-solving skills to work. Every stage demanded close observation, clear communication and a little creative thinking.The team cracked every riddle before time ran out and escaped with the truth intact. This outing brought everyone together outside the office for an afternoon of teamwork, friendly pressure and a very unconventional tour of Kingston’s beautiful downtown and waterfront.#EngineeringExcellence #YGK #TeamBuilding ...

    No, Callidus Engineering has not rebranded. Our graphic designer is simply on vacation, and the rest of us were left unsupervised. Questionable graphic design choices aside, our mechanical and electrical engineering work continues as usual. Proper branding returns next week. Buildings still need to work in the meantime. #EngineeringExcellence ...
