The inspection shall include, but not be limited to, general condition and cleanliness of all exterior and working parts, and any evidence of large or small leaks from steam or hot water equipment, emissions, pipes, valves, and covers. The Contractor shall submit a report outlining the results of the inspection to the COR/ACOR within three (3) working days.

However, any defects identified by the Contractor shall be submitted in writing to the COR on the same workday.

2.8 Boiler/Heat Plant Shutdowns. The Contractor shall inform the COR within thirty

(30) minutes of shutting down any boiler or heating plant for unplanned repairs. The Contractor shall provide written notice 30 days in advance of planned repairs that require the shutdown of any boiler or heat plant, unless shutdown is otherwise requested by the COR.

2.9 Boiler Water Treatment Chemicals. The Contractor shall supply the chemicals necessary to maintain all boiler water chemistry IAW TM 5-650 Central Boiler Plants.

2.10 Boiler Water Test Samples. In addition to the required boiler and distribution system water testing and treatment, the Contractor shall submit monthly, a series of boiler plant water samples to a Government designated lab as directed by the COR/ACOR. Analysis, results, and comments will be sent to the Contractor. The Contractor shall pay the costs for submission and lab analysis of these samples. The Contractor shall pay lab analysis costs directly to the Government designated lab. The water samples submitted each month shall include a boiler water sample, a condensate sample, and the Contractor plant test results for these samples. Test results and water samples from one (1) boiler/condensate system are required from each of the high-pressure boiler plants operated for the Government.

Additional tests may be required if the Contractor's test results and the lab's test results vary by 10 percent. Additional tests shall be at the Contractor’s expense. The Contractor shall provide copies of Lab Water Analysis Reports to the COR within five (5) days after receipt.
