Test reports shall show the results of the testing, including the dates/times of the tests, location of tests, and results (contaminant levels). Include a list of HVAC system deficiencies observed during the testing, if any. D. Sequencing: 1. Testing shall be performed after air and water balancing is complete. 2. Testing shall be performed after all interior finishes are installed, including but not limited to millwork, carpet, paint, doors, wall coverings, and acoustic tiles. 3. Testing shall be performed after commissioning is complete related to the HVAC and control systems. Commissioning shall verify proper operation of equipment, drain pan operation, filter installation and shall eliminate any obvious sources of contamination. 4. Testing shall be performed prior to building occupancy. 5. Testing shall be performed prior to the installation non-fixed furnishings such as systems furniture and/or moveable furniture. 6. During testing, construction activities in the area of testing shall be held to a minimum. E. Scheduling: The testing shall be incorporated into the master project schedule. Indicate critical path items. Coordinate with the lead contractor. F. Coordination: The air balancer, BAS installer, General contractor and HVAC contractor shall assist the Testing Agency by setting the HVAC systems to the proper operating modes, installing clean filters prior to testing, and coordinating other construction activities in the area which may affect the tests. G. Testing Agency: Testing agency shall have minimum 5 years experience in the types of testing specified herein. Testing Agency s credentials and resume shall be submitted for approval prior to start of testing. 1.
