Project Deficiency Reports

Any deficiencies or problems that would prevent us from performing our work or that would affect the satisfactory operation of the HVAC system, will be communicated to the mechanical contractor or the responsible party in the form of a written deficiency report signed by the field technician. If the deficiency causes a work shortage and occasions us to pull off the project, we will check back periodically. We would also expect to be notified that the deficiencies have been corrected and when to proceed. The deficiency reports are sent out on a daily basis via fax or mail to the responsible party and a copy is maintained in our job file.

Reports

All reports are submitted in booklet form containing test sheets of the various apparatus installed on the subject projects. Recorded data includes: equipment, unit number and location, manufacturer, model number, serial number and operating conditions specified and actual. For terminal devices, the number of the device with the associated prime mover is listed on the recorded air terminal test sheet. The report could also contain a summary or remarks and recommendations. Reports are reviewed and stamped by our NEBB Certified Supervisors, issued on NEBB approved forms completed by our technicians using notebook computers to record retrieved data.
