Commissioning Plan, lune 24, 2015 o Start-up by Installing Contractor: All systems must be inspected point-to-point and tested prior to start-up, and start-up must be completed per manufacturer's instructions. Any issues discovered during start-up must be resolved by the installing contractor. Check all operating modes, interlocks, control responses, and responses to abnormal or emergency conditions, and verify proper response of building automation system controllers and sensors. o All systems are to be tested and verified for the intended operation of all components and system interactions in various conditions and modes of operation. Testing is to start with components, move to subsystems, then systems, then to interlocks, controls and connections between systems. o Tests are to be completed by the testing engineer, general contractor, and subcontractors, with the owner's maintenance staff present in order to maximize their training time. o Simulated conditions may be required by the use of artificial loads when it is not practical to test under design conditions. Installing contractor to provide equipment to simulate loads. Set simulated conditions as explained in the Commissioning Specifications and document simulated conditions and methods of simulation. Return settings to normal operating conditions after tests. o Any Acceptance Tests required per the California Energy Code must be completed by the installing contractor and any special inspectors (e.g., "HERS Raters"), and all acceptance test forms and reports must be completed with copies provided to the Commissioning Provider. c Installing contractor to provide a list of all test equipment used including manufacturer, model number, serial number, and date of last calibration. Provide an updated report if any instruments are added while testing is in process. c For temperature measurement: ■ Range: Minimum +14°F to 248°F ■ Type: Thermometer, Digital Electric ■ Minimum Accuracy: +1- 5 OF ■ Calibration Interval: Per manufacturer instruction, not exceed every 12 months. a For hydronic pressure and differential pressure measurement: ■ Range: 0 to 30 psi, 0 to 60 psi, and 0 to 200 psi. • Type: Calibrated test gauges, 3 inch, or electronic digital device (TSI or similar) meeting accuracy and calibration interval requirements. ■ Minimum Accuracy: 2% of scale (Gauge), 3% of reading (electronic) ■ Calibration Interval: Per manufacturer instruction , not exceed every 12 months ■ Note: Use lowest range instrument or scale o For air pressure measurement: ■ Range: 0 to 1 inch w.c., 0 to 4 inch w.c., and 0 to 10 inch w.c. ■ Type: Use properly leveled and zeroed manometer, Magnehelic or electronic instrument meeting accuracy requirements ■ Minimum Accuracy: 2% of reading (Magnehelic), 3% of reading (electronic) ■ Calibration Interval: Per manufacturer instruction , not exceed every 12 months ■ Note: Use lowest range instrument or scale 4of8
