Prepare and complete a Functional Performance Test Checklist for each item of equipment or system.

3.2.6.7.3 Seasonal Tests

Regardless of the season, perform initial Functional Performance Tests of equipment and systems at the time of system completion. Develop and implement means of artificial loading to demonstrate, to a reasonable level of confidence, the ability of the HVAC systems to handle peak seasonal loads.

In addition to the initial Functional Performance Tests, perform Functional Performance Tests of the HVAC systems during peak heating and cooling seasons during outdoor air condition design extremes. Schedule the seasonal Functional Performance Tests in coordination with the Government.

Systems may be partially accepted by the Government prior to seasonal testing if they comply with all construction contract and accepted design requirements that can be tested during the initial Functional Performance Tests. All Functional Performance Test procedures must be completed prior to full systems acceptance.

3.2.6.7.4 Aborted Tests and Re-Testing

Abort Functional Performance Tests or Seasonal Tests if any deficiency prevents successful completion of the test. Reimburse the Government for all costs associated with effort lost caused by re-testing due to test failures and aborted tests. These costs must include salary, travel

SECTION 01 46 00.00 06 Page 17 costs, and per diem for Government commissioning team members. Re-test only after all deficiencies identified during the original tests have been corrected.

3.2.6.7.4.1 100 percent Sample

Systems or items of equipment for which 100 percent sample are tested fail if one or more of the test procedures results in a discovery of a deficiency and the deficiency can not be resolved within 5 minutes during the test. Upon test failure, abort the test of the system or item of equipment. Schedule a re-test, in coordination with the Government, only after all deficiencies for all failed equipment and systems have been corrected.

Re-test to the extent necessary to confirm that the deficiencies have been corrected. At the sole discretion of the Government, all test procedures for the failed item of equipment or system must be repeated to confirm that no deficiencies remain within that equipment or system.

3.2.6.7.4.2 Less than 100 percent Sample

For systems or equipment tests with a sample size less than 100 percent, if one or more of the test procedures for an item of equipment or system results in discovery of a deficiency, regardless of whether the deficiency is corrected during the sample tests, the item of equipment or system fails the test. Correction of the deficiencies during Functional Performance Testing may be performed only at the sole discretion of the Government.

If the system failure rate is 5 percent or less, meaning that 5 percent or less of the equipment or systems had at least one deficiency, re-test only the items which experienced the initial failures.

If the system failure rate is higher than 5 percent, meaning that more than 5 percent of the equipment or systems tested had at least one deficiency, re-test the items which experience the initial failures. In addition, test another sample of the same size as the initial sample for the first time. If the second sample set has any failures, re-test those failed items and all remaining equipment and systems to complete 100 percent testing of that system type.

3.3 SYSTEMS TRAINING

The training specified by the specification sections associated with commissioned systems must be provided by certified technicians or trainers. Include both demonstration of proper equipment and system operation both at the equipment and classroom training. For the classroom training, include proper operating and maintenance procedures, preventative maintenance requirements and procedures, trouble-shooting procedures, and calibration frequency and procedures. Include identification of the equipment and system warranties and procedures for correction under the warranties. Include a review of the draft systems manual, maintenance plan, and service life plans.

Visibly and audibly record the systems training. All instruction on the recording must be clear and intelligible.

3.4 TRAINING PLAN

Develop a training plan which identifies all training required by specification sections associated with commissioned systems. Include a matrix listing each training requirement, content of the training, the trainer name, trainer contact information, and schedule and location of training.

Document training attendance using Training Attendance Rosters and provide completed attendance rosters to the Lead Commissioning Specialist and the Government.

3.5 SYSTEMS MANUAL

Prepare and submit a Systems Manual including a signed certification or letter from the Lead Commissioning Specialist and Electrical Commissioning Specialist stating that the Systems Manual is complete, clear, and accurate. The Systems Manual, for all commissioned systems, must conform to Appendix A SYSTEMS MANUAL ORGANIZATION AND CONTENT to ER 25-345-1 , available at the USACE Publications website at the following location:

https://www.publications.usace.army.mil/USACE-Publications/Engineer-Regulations/ Update and resubmit the Systems Manual based on any corrective action taken during the warranty period.

3.6 CURRENT FACILITIES REQUIREMENTS AND O&M PLAN

Prepare and submit a Current Facilities Requirements and O&M Plan document that contains information necessary to operate the building efficiently.

Include the following:

a. Sequences of operation for all commissioned systems.

b. Building occupancy schedule.

c. Equipment run-time schedules.

d. Setpoints for all HVAC equipment.

e. Set lighting levels throughout the building.

f. Minimum outside air requirements.

g. Changes in schedules or setpoints for different seasons, days of the week, and times of the day.

h. Systems narrative describing the mechanical and electrical systems and equipment.

i. Preventative maintenance plan for building equipment described in the systems narrative.

j. Commissioning program including periodic commissioning requirements, ongoing commissioning tasks, and continuous tasks for critical facilities.

Information from other submitted documents may be referenced from the current facilities requirements and O&M plan in lieu of repeating information provided that the reference includes the location of the information in those other submitted documents such as page number or

SECTION 01 46 00.00 06 Page 19 chapter or part and section.

3.7 COMMISSIONING REPORT

Following the completion of Functional Performance Tests, with the exception of Seasonal Tests, the Lead Commissioning Specialist must prepare a Commissioning Report including an executive summary describing the overall commissioning process, describing the results of the commissioning process, listing any outstanding deficiencies and recommended resolutions, and describing any seasonal testing that must be scheduled for a later date. Indicate, in the executive summary, whether the systems meet the requirements of the construction contract and accepted design and the Owner's Project Requirements.

Detail any deficiencies discovered during the commissioning process and the corrective actions taken. Include the completed Building Envelope Inspection Checklists, Pre-Functional Checklists, Functional Performance Test Checklists, the Construction Phase Commissioning Plan, the Issues Log, Performance Verification Test Reports, Training Attendance Rosters, the Design Review Report, and the final TAB Report.

Following any Seasonal Tests or Post-Construction Activities, update the Commissioning Report to reflect any changes and resubmit.

3.8 POST-CONSTRUCTION SUPPORT
