More than ever before, building commissioning is a vital component of any new construction, renovation or expansion. Gone are the days of the building that just houses advanced technology. Modern facilities incorporate high-end technologies throughout. Building commissioning provides a comprehensive approach to quality assurance for a buildings entire infrastructure. Such systems may include heating and air conditioning, plumbing, electrical, safety equipment and security systems. Commissioning ensures a new facility begins its life cycle at optimal productivity with all systems operating as intended. GL2M Engineering's brings together a small group of engineers committed to the goal of helping buildings work better through this process commonly referred to as building commissioning. Combining years of mechanical and electrical design experience with special emphasis on energy efficient operation for both new and existing buildings, GL2M has focused on refining the methods that ensure successful design, construction and operation of our client’s buildings.
