Review of a separate item as such will not indicate approval of assembly in which item functions.

B. Affix stamp and initials or signature, and indicate requirements for resubmittal, or review of submittal.

Engineer's action on submittals is classified as follows:

1. Reviewed: Submittal has been reviewed and appears to be in conformance to design concept of

Project and Contract Documents. Contractor may proceed with fabrication of work in submittal.

2. Reviewed As Noted: Submittal has been reviewed and appears to be in conformance to design concept of Project and Contract Documents, except as noted by reviewer. Contractor may proceed with fabrication of work in submittal with modifications and corrections as indicated by reviewer.

3. Reviewed As Noted-Resubmit: Submittal has been reviewed and appears to be in conformance to design concept of Project and Contract Documents, except as noted by reviewer. Contractor may proceed with fabrication of work in submittal with modifications and corrections as indicated by reviewer. Contractor shall make any corrections indicated by reviewer and resubmit for review.

4. Resubmit: Submittal has been reviewed and appears not to be in conformance to design concept of Project or with Contract Documents. Contractor shall not proceed with fabrication of work in submittal, but instead shall make any corrections required by reviewer and resubmit for review.

7. Void: Submittal is voided because it is no longer required or has been superseded by another submittal.

C. Return 1 copy of submittals to Contractor. Contractor shall make additional copies as required.

D. Review of submittals shall not relieve Contractor from responsibility for any variation from Contract Documents unless Contractor has, in writing, called Engineer's attention to such variation at time of submission, and Engineer has given written concurrence pursuant to Contract Documents to specific

SECTION 01 33 00 - Page 3 variation, nor shall any concurrence by Engineer or other reviewer relieve Contractor from responsibility for errors or omissions in submittals.

SECTION 23 05 23 - Page 3

3. The bearings shall be of sufficient length and designed in a manner to minimize the load and wear

4. The bearings shall include a separate and replaceable seal of graphite to eliminate media and solids ingress.

I. Pressure Rating: The pressure rating of the valve shall be in accordance with ASME B16.34

J. Testing:

1. The valve body shall be hydrostatically tested per API 598 to 150% of the maximum design pressure.

2. No leakage shall be detected through the valve body.

3. Each valve shall be tested for seat leakage in both directions with both liquid and air in accordance with API 598 for resilient seated valves. Valve leakage shall be zero.

K. Actuators: All valves shall include a self-locking manual gear operator as standard.

2.03 CHAINWHEEL ACTUATORS

A. Description: Valve actuation assembly with sprocket rim, brackets, and chain.

1. Sprocket Rim with Chain Guides: Ductile iron, of type and size required for valve.

2. Brackets: Type, number, size, and fasteners required to mount actuator on valve.

3. Chain: Hot-dip, galvanized steel, of size required to fit sprocket rim.

PART 3 EXECUTION

3.01 EXAMINATION

A. Examine piping system for compliance with requirements for installation tolerances and other conditions affecting performance.

1. Proceed with installation only after unsatisfactory conditions have been corrected.

2. Modify piping as necessary for installation of new valves. Contractor is to verify piping connection dimensions prior to ordering valves.

B. Examine valve interior for cleanliness, freedom from foreign matter, and corrosion. Remove special packing materials, such as blocks, used to prevent disc movement during shipping and handling.

C. Operate valves in positions from fully open to fully close. Examine guides and seats made accessible by such operations.

D. Examine mating flange faces for conditions that might cause leakage. Check bolting for proper size, length, and material. Verify that gasket is of proper size, that its material composition is suitable for service, and that it is free from defects and damage.

E. Do not attempt to repair defective valves; replace with new valves.

3.02 VALVE APPLICATIONS

A. Refer to piping Sections for specific valve applications. If valve applications are not indicated, use the following:

1. Shutoff Service: butterfly valves.

B. Chilled Water Systems: Use the following valve types:

1. 14” Butterfly Valves: as specified above for valves noted as follows on plans (CHS Valves

3,4,5,6,7,8 and CHR Valves 3,4,5,6,7 and 8)

C. Condenser Water Systems: Use the following valve types:

1. 16” Butterfly Valves: as specified above for valves noted as follows on plans (CWS Valves

3,4,5,6,7,8 and CWR Valves 3,4,5,6,7 and 8)

3.03 VALVE INSTALLATION

A. Drawings indicate general arrangement of piping, fittings, and specialties. Contractor shall verify valve locations, dimensions, connection styles and dimensions with existing conditions prior to ordering valves. Contractor shall modify piping as required for installation of valves.

B. In general, install valves as per manufacturer’s instructions.

C. Install valves with unions or flanges at each piece of equipment arranged to allow service, maintenance, and equipment removal without system shutdown.

D. Locate valves for easy access and provide separate support where necessary.

E. Install valves in horizontal piping with stem at or above center of pipe wherever possible.

F. Install valves in position to allow full stem movement.

G. Install chain wheel operators on valves NPS 4 (DN 100) and larger and more than 96 inches (2400 mm) above floor. Extend chains to 60 inches (1520 mm) above finished floor elevation.

3.04 ADJUSTING

A. Adjust or replace valve packing after piping systems have been tested and put into service but before final adjusting and balancing. Replace valves if persistent leaking occurs.

3.05 REINSULATION OF PIPING AND NEW VALVE BODIES

A. Reinsulate all chilled water piping where insulation was removed for installation of valves with insulation that is of the same construction of the existing insulation serving chilled water system.

Insulate valve bodies complete and seal to provide complete vapor barrier around working chilled water system.

3.06 CLEANING DURING CONSTRUCTION

A. Execute periodic cleaning to keep work, site, and adjacent properties free from accumulations of waste materials, rubbish, and windblown debris, resulting from construction operations.

B. Provide on-site containers for collection waste materials, debris, and rubbish.

C. Remove waste materials, debris, and rubbish from site periodically and dispose of at legal disposal areas away from site.

D. Dispose of waste materials, debris and rubbish at designated dumping area on Owner's property.

3.07 FINAL CLEANING

A. Employ skilled workers for final cleaning.

B. Remove grease, mastic, adhesives, dust, dirt stains, fingerprints, labels, and other foreign materials from sight-exposed interior and exterior surfaces, as well as all tools, appliances, construction equipment and machinery, and surplus materials.

C. Prior to final completion, or Owner occupancy, Contractor shall conduct inspection of sight-exposed interior and exterior surfaces, and all work areas, to verify that entire Work is clean.

D. Contractor shall broom clean exterior paved surfaces; rake clean other surfaces of the grounds, so as to leave site ready for occupancy by Owner, and restore those portions of site not designated for alteration by Contract Documents to their condition as of beginning of Work.

B. Distribute Samples which carry Engineer stamp as either "Reviewed" or "Reviewed as Noted" as directed by Engineer.
