Due to time constraints and facility management manning, site visits will not be possible.

The state conveyance number for the elevator is: SC65129X 141529

This requirement was previously awarded to Capitol Elevator under contract 12905B24P0020.

It is a hydraulic elevator.

The CAT 5 and semiannual inspections are required this year so yes, they should be included in the contract. I don’t believe you need both a CAT 1 and CAT 5 inspection.

They can be done at the same time. The CAT 5 inspection can include the scope of the CAT 1 inspection however, they both need to be reported. The option years should include the CAT 1 and semiannual inspections. The Contractor shall provide any needed equipment to perform the pretest examinations and tests at no additional cost. The Contractor shall also provide all necessary weights and testing equipment to perform tests and assist the inspector at no additional cost.

Annual inspections need to be performed by the contractor.

Deficiencies should be addressed by the contractor. Aside from any major repairs, any normal issues will be handled by the contractor and covered by the contract. Major repairs will be handled separately from this contract and not included in the price.

MAINTENANCE INSTRUCTIONS

I. GENERAL MAINTENANCE

Like all equipment of this type on the market today, it is designed, manufactured and installed to minimize maintenance. However, maintenance must be provided to prolong the life of your equipment and protect your investment.

A planned sequential procedure, regularly performed, will keep your maintenance cost to an absolute minimum and ensure realization of the long trouble-free service the equipment was designed to deliver. Cleanliness of the elevator components, machine room and hoistway cannot be overstressed in its importance. A program of planned maintenance should begin the day the elevator goes into service. Failure to provide this regular maintenance when the equipment is new will eventually result in premature failure of components with consequent equipment breakdown.

CAUTION: Every precaution should be taken when servicing any elevator. Whether specifically mentioned here or not common sense precautions should be followed, making sure life and limb of the serviceman and the public is not endangered.

Make certain all voltage is removed before touching any parts of the electric controller, power unit or when servicing any part of the oil system. The proper interval for servicing varies with conditions of use, but should be at least semi monthly. When.access to the pit or hoistway becomes necessary, exercise all safety precautionary measures to the fullest.

II. JACK

Since the jack packing is most vital to smooth operation and conservation of oil, check the packing at regular intervals for excessive leakage which will accumulate in the elevator pit, and for gritty materials in the packing which will damage the finish of the jack plunger. If packing is damaged or there is excess leakage replace with original factory packing.

ID. GUIDE RAILS AND SHOES

The guides should be checked at regular intervals for conditioning and adjustment.

Check clearance between guide shoes and the guide rails. All bolts holding the shoes in place should be tight. Check that all bolted connections on the guide rail and equipment are securely fastened thereto. Guide rail lubricators, when used, are located on the elevator car. The level of oil in these lubricators should be checked at regular intervals and refilled when low.

maintenance instructions, continued

Where roller guides are used, no lubrication is required, either on the rails or roller guides themselves. The rails should be kept smooth and free from rust. Although the roller guide bearings are lifetime lubricated, check the roller to be sure they are properly adjusted, so that the load is evenly divided on each roller. Keep the hoistway and pit clean.

IV. CABS

The cab should be visually inspected for burned out lamps, damaged flooring or carpeting, and damage to cab fixtures. All bolted connections on the cab should be tightened securely.

The car sill should be kept clean at all times as trash in the grooved sill can affect proper door closing.

The car push button station must be kept clean as dirt or water can cause electrical damage.

Basic items to inspect are:

1. Free operation of all pins in the linkage mechanism on the doors; sparingly lubricate.

2. Check brushes regularly on DC motors and replace when sufficiently worn.

3. Proper operation of the switch and cam that governs acceleration and deceleration of the drive motor.

4. Smooth operation of the pick-up clutch and roller.

5. V belts on the drive wheel should be in good condition; watch for fraying or splitting belts. Where chain drive is used, lubricate lightly with suitable chain lubricant.

6. See Lubrication Chart.

V. POWER UNIT

The oil in the elevator is important to the elevator system. It must be kept clean at all times. Cleanliness of the oil cannot be stressed enough. Tank filters should be checked at regular intervals and cleaned whe:µ necessary. The oil should be checked regularly and cleaned or replaced when dirty.

The pump should be checked regularly for leakage. Clean the strainers in the tank and oil line if provided. Check the motor in the power unit and lubricate accordingly. V belts, when used, should be kept taut and free of oil. Inspect belts for splitting and fraying, replacing when necessary. Where a direct connection between the motor and maintenance instructions, continued pump is used, the :flexible coupling should be checked for worn out cushions and for misalignment. Check all hoses for deterioration or softening and clamps for tightness.

VI. HATCH SWITCHES

Check switch brackets to make sure that they are tightened securely. All mechanical switches should be inspected for wear of the roller tire condition of contacts.

VII. OPERATION

Check to see if the car runs smoothly and levels into the :floors properly. The car should stop within plus or minus ¼" from the floor.

CARE AND CLEANING OF ARCHITECTURAL METALS

Listed below are suggested care and cleaning instructions and typical products for use by building owners. Qualified professionals should handle any cleanup or refreshing, other than routine.

#4 BRUSHED and #7 or #8 MIRROR FINISHED STAINLESS STEEL

Routine cleaning with a mild dishwashing liquid removes fingerprints, smears and everyday liquids such as soda, coffee, and other beverages. Consumer type glass cleaners are also effective on :fingerprints and beverage spills; a good stainless steel cleaner can also be used.

Do not use abrasives such as scouring powders.

#4 BRUSHED and #7 or #8 MIRROR FINISHED MUNTZ (BRONZE)

Only routine care and cleaning is recommended. The surface should be waxed weekly with paste wax, or more often depending upon building traffic. The wax puts a protective coating over the lacquer and reduces scuffing. Do not use any abrasives or chemical cleaners as this type of product will cause damage. Recommended cleaning to remove spills, smears and fingerprints is with a soft cloth dampened with plain tap water. If this recommendation is not followed, early failure of the coating is imminent.

PAINTED FINISHES

Routine cleaning with a mild detergent, soap and water will remove fingerprints, smears and everyday type liquid spills such as soda or coffee. Do not use any abrasive powders or harsh chemicals.
