Commissioning
AH&P is certified by the National Environmental Balancing Bureau (NEBB) in the disciplines of Building Systems Commissioning (Cx) and Testing and Balancing (TAB). AH&P currently has two NEBB Certified Professionals and one NEBB Certified Technician on staff. Our Certified Professionals, Certified Technicians, Engineers, and Designers are members of NEBB, USGBC, ASHRAE, NFPA, NICET, IEEE, NAIES, ASPE and several other professional organizations. AH&P’s Cx/TAB Department is unique because of the broad knowledge available among AH&P’s Engineers combined with the field experience of the NEBB CP’s and CT’s. AH&P’s Cx/TAB department maintains a full set of highly accurate instruments which are calibrated on a regular basis. The accuracy and resolution of the instruments meet NEBB’s strict specifications, and AH&P’s Cx/TAB department utilizes these instruments to diagnose hidden issues within building systems.
Construction Administration
AH&P has a full time construction administration department. Jim Hughes, P.E., heads this department. He and his staff visit our projects one to four times per month to insure the construction materials and workmanship comply with the contract documents. Jim also expedites submittal reviews, answers to requests for information (RFI’s) and change order review and approval to keep the construction process moving and on schedule.
