At The HIDI Group, we have always placed importance on ownership and transparency – as a 100% employee owned company, we enable our team to play a vital part in the firm’s direction, decision-making, and sharing of our founding principles and values.



Passionate about fueling client success through the delivery of integrated solutions, we analyze Mechanical Design, Electrical Design, Fire Protection Design, Architectural Lighting Design, Communications & Audiovisual (AV), Security & Risk Design, Energy Services, and Commissioning Service in tandem to maximize efficiency, minimize operating costs, and manage risk. This multidisciplinary approach yields synergies that result in projects of the highest quality, and efficiencies with regards to design, budget, human capital and timelines.

Mechanical systems have a direct impact on the human experience within any building. Human comfort is not just a thermal issue; it comes from the knowledge that our lives and the properties we inhabit are protected by integrated fire protection systems, clean tap water, responsible energy usage, prime indoor air quality, and proper process requirements. We effectively engineer optimal environments, and frequently update our knowledge and skills to develop and deliver state-of-the-art systems. Through teamwork, creativity, and cutting edge expertise, we develop appropriate solutions that balance performance against capital and operating costs.
