21 00 01 Owner General Requirements and Design Intent

.01 General

1. Provide fire protection systems unless exempted by the local code, and FM Global.  A fire standpipe protection for buildings during construction should be referenced to the requirements of the code, the fire department and FM Global.
2. If requested by the University, an approved automatic fire-suppression system shall be provided where solvents and/or explosive materials are stored or used, and in kitchens over appliances which produce grease-laden vapors.
3. Professional Note:  The University has established specific quality assurance requirements for installation of sprinkler systems protecting areas of 1,000 square feet or greater in new buildings and renovation projects.  Consult with the University Project Manager for the proper terminology to be incorporated in the project specifications.

.02 Design

1. Design systems in accordance with the local code, the requirements of the local fire department, BOCA, applicable NFPA Standards and FM Global standards.
2. For a few isolated sprinklers, use 100 square feet, ordinary hazard pipe schedule with sprinklers at least 50° above ambient temperature.  A fire department pumper connection is not required.  Water flow and valve tamper should be monitored.  Inspector's test is required at the end of the system, along with a drain close to the control valve.

.03 Submittals and Approvals

1. All devices and equipment installed in the systems must be approved and listed by Underwriters Laboratories and Factory Mutual Research Corp., (FMRC).
2. Early contact with FM Global by the Professional is suggested.
3. Prior to final approvals by the University, the Professional shall submit plans and specifications to FM Global for their approval and submit these approvals to the University.
4. Final Contractor's shop drawings and specifications shall be submitted to FM Global for their approval prior to submittal to the Professional for his approval.

.04 Hydrant Tests

1. All projects involving street-pressure sprinkler systems, street-pressure fire standpipe systems or fire pumps require hydrant tests on the mains in all streets that could be used to feed the building.  Since these tests take time to get, they should be initiated as soon as possible at the start of a project.  Have a hydrant flow test made by the local water department, water company, or FM Global.  At University Park, flow data is available from the Utilities System Engineer.  Any flow data obtained from University utilities or local water departments should be confirmed with FM Global before being used for design basis.

.05 Utilities (Refer to Division 33 00 00)

.06 Mechanical Rooms

2. Coordinate and comply with other applicable mechanical room requirements as described in 23 00 01.06.

.07 Janitor Rooms

1. Janitor rooms are not accessible to maintenance employees.  Therefore, mechanical equipment, valves, electric panels, thermostats, etc. are not to be placed in these rooms.

21 01 00 OPERATION AND MAINTENANCE OF FIRE SUPPRESSION

1. Coordinate and comply with all applicable general Operation and Maintenance requirements as described in 23 01 00, adapted to all Fire Suppression systems, equipment and controls.

4. Access panel locations shall be indicated on contract drawings.
5. Access panels are not required in lay-in ceilings, but identify appropriate tile with color button, cleated through, located on the adjacent ceiling grid.  Use color code of principal service.

.03 Motors and Drives

1. Motors
1. All motors over 1/2 hp shall be ball bearing unless otherwise noted.
2. All ball bearing motors shall be equipped with lubricating type bearings, and provided with one (1) grease fitting per bearing and one (1) removable plug per bearing in the bottom of the grease sump to provide for flushing and pressure relief when lubricating.  Motors shall be permanently marked that bearings are lubricating type bearings.  Where motor grease fittings are not accessible, extend 1/8" steel or copper tubing from fitting to an accessible location.
3. Motors 3/4 hp and larger to be three phase, 60 hertz.
4. Motors smaller than 3/4 hp to be single phase, 60 hertz, 120V and shall have built in thermal protection.
5. All motors above 1 hp shall be the low loss - high efficiency type.  Motors shall be tested in accordance with NEMA standard MG1 1.536 and name plate shall indicate the index letter.
6. All 3-phase motors larger than 5 hp shall have power factor correction capacitors as recommended by the manufacturer.
7. Motor inrush current must not create a voltage sag in excess of 3 percent without specific University approval.
8. A voltage sag report shall be completed by the Professional on selected projects as determined by the University.  Report shall include backup calculations and expected building voltage sag when motor or motors in question are started.
9. The University has experienced widespread premature motor shaft bearing failures due to fluting from electrical arcing on motors equipped with Variable Frequency Drives.  The Design Engineer must specify appropriate technologies and/or include provisions in the system design to prevent electrical fluting induced premature bearing failure from occurring.
2. Drives
1. All belt driven equipment shall include properly selected adjustable sheaves and matched V belts, all rated for 150% of motor horsepower.  Proper expanded metal guards should be provided for safety protection and to allow for proper ventilation for cool operation of belts.  Solid sheaves and band belts shall be used to minimize vibration in multiple V-belt driven equipment.
