Where "Project Manager" is used in this Specification, we mean that person so designated by the Owner. 2. DRAWINGS AND MEASUREMENTS A. Contract drawings for mechanical work are in part diagrammatic, intended to convey the scope of work and indicate general arrangement of equipment, ducts, conduits, piping, and approximate sizes and locations of equipment and outlets. Mechanical trades shall follow these drawings in laying out their work, consult general construction drawings to familiarize themselves with all conditions affecting their work, and shall verify spaces in which their work will be installed. Coordinate work with other trades as job conditions reasonably require. B. Where job conditions require reasonable changes in indicated locations and arrangement, make such changes without extra cost to Owner. C. The drawings are not intended to be scaled for roughing in measurements nor to serve as shop drawings. D.

A letter must be obtained by the Contractor and be filed with the Engineer's Office, if the tests were witnessed by the Owner. Where required, perform such tests in the presence of local or state building inspection officials. Bobcat Ridge Residence 15010 - 4 15010.doc – 5/26/2006 Bid Issue B. General 1. The pipe systems shall be tested to assure they are installed leak tight and structurally safe for the intended purpose. 2. Cleaning and flushing tests and approvals shall be completed before performing pipe system tests to eliminate retesting. 3. If the pipe tests fail, the pipe system shall be repaired and retested. 4. The installing supervisor shall confirm the safe test pressure for vessels, equipment and accessories in the pipe system from drawings, specifications, or name plate data. 5. Notify the Owner's Project Manager 24 hours in advance of each test. C. New System Test 1.

Remove or block and vent direct operated or self-contained regulators. Each part of a pipe system shall be tested, divided as indicated, for the time specified for the given class of test. 2. Safety valves, relief valves, and rupture discs shall be removed during the pipe system test and reinstalled after the test. New gaskets shall be used when reinstalling all flanged items. Do not change spring settings or make inoperative any safety and relief valves, except valves designed to be pinned or yoked. Normally closed control valves shall be opened before test. 3. Piping and vessels shall be vented when draining them to prevent their collapse by vacuum. 4. The pipe system installer shall provide all necessary connections, vents and drains to test and drain the system completely. 5. Allowance shall be made by the Project Manager for variations of pressure and volume due to temperature changes in determining satisfactory maintained test pressure. 6. The Project Manager shall check the test pressure at the beginning and end of each test before acceptance of the system. 7. Pipe systems shall be tested and accepted before insulation, paint, or other covering or coating is applied.
