Bore Hole vs. Holeless Jacks

Many of today's hydraulic elevators have jacks located inside the hoistway and thus a bore hole is not required. Further, there are environmental benefits to installing holeless pistons which the local Planning authority welcomes as it eliminates the risk of in-ground contamination of petroleum-based hydraulic fluids. We recommend you consult Bermuda Elevator to determine the best model for your installation. If however, you have an existing in-ground piston that needs replacement, we have wide experience in the safe extraction and replacement of the jack that is cost-effective and efficient.

Temporary Service

Should a Purchaser require use of any elevator(s) prior to substantial completion and final acceptance, the Purchaser agrees to sign Bermuda Elevator’s Construction Use Only Agreement, and be bound by the terms and conditions thereof. Any permit fees for temporary service shall be paid by Purchaser.

Work Not Included

Bermuda Elevator’s proposal does not include the following work, and is necessarily conditioned on the proper performance of the General Contractor or their subcontractors. Most items below are requirements of the authority having jurisdiction (AHJ), the Bermuda Government's Dept. of Planning.

2. A fixed vertical ladder of non-combustible material for pits over 35” h. It should extend from floor upward not less than 48” above the bottom landing floor level. Refer to elevator shop drawing for exact location.

3. A permanent light fixture (guarded and min. 100 lx) and ground fault receptacle on a separate branch circuit shall be provided and mounted 12” off pit floor on rear wall with switch to be located 18” above lowest landing adjacent to pit ladder. Wiring to conform to National Electric Code ANSI/NFPA No. 70.

4. (Hydraulic units): The well hole area around the plunger and cylinder must be sealed.

5. Adequate supports and foundations to carry the loads of all equipment (car, capacity, jack, buffers, etc.) at pit floor.

6. Provide chases through walls and/or floor etc. for installation of conduit and oil line (for hydraulic unit) as necessary. Consult BESL for location and sizing of sleeves.

Hoistway & Entrances

1. During construction, scaffolds with secure platforms are required in hoistway for initial setting out and guide rail bracket installations. Please consult Bermuda Elevator prior to erection of scaffold to ensure adequate clearances.

2. Removable barricades to prevent fall protection. (42” top rail, 21” mid rail, 4” kickboard able to withstand 200 lbs of force.

3. Leave out entire front wall where openings occur so that entrances can be set in proper relation to rails in hoistway or provide rough openings 18” wider and 12” higher or as noted on layout drawings provided by Bermuda Elevator.

4. All sills and elevator machine beams must be grouted

5. Provide finished floor material thickness at each landing for setting our door sills.

6. Pockets (located by Bermuda Elevator) for mounting signal fixtures & the finishing of walls at entrances

7. Inside Hoistway walls shall be flush on sides. Any projections or setbacks over 4” shall be provided with a bevelled angle not less than 750. Any holes must be filled in.

8. Fire-resistive construction throughout shall conform to the building code requirements.

9. Provide hoisting ‘I’ beam at top of hoistway for lifting equipment into place.

10. Provide adequate supports for guide rail brackets. Blockwork to be filled with concrete. If hoistway is constructed of drywall, mount metal plates to structure for support.

Elevator Cab

1. Elevator cab flooring or assistance with its installation. Confirm with us regarding floor thickness allowance prior to ordering the elevator.

2. Telephone connection to elevator controller (must be a dedicated line and monitored 24 hours. Bermuda Elevator will connect from controller to cab.

Equipment Room

1. Fire-resistive construction shall conform to the building code requirements.

2. GFCI receptacle and permanent lighting with minimum illumination of 200 lx. Switch to be located within 12” of door strike jamb.

3. An independent means of air conditioning to maintain a temperature between 50O to 80O F

4. Access door shall be 2-hr. labelled, min. 36”w x 80”h, self-closing, self-locking and openable from inside without a key.

5. Lockable fused disconnect shall be provided with power feeder wires to elevator controller, piped and sized for each elevator controller depending on motor size, 3-phase source, and starting/full load amps. Consult Bermuda Elevator for specific requirements.

6. Branch circuit disconnect and wiring to controller for car light and fan must be lockable in open position. It shall be sized for noontime delay fuses, thermal circuit breaker and dual element time delay. Consult Bermuda Elevator for specific requirements.

7. Owner/General Contractor to provide a bonded ground wire, properly sized, from the elevator controller(s) to the primary building ground

8. Fire extinguisher (Class ABC) mounted on wall adjacent to the door.

9. Clear headroom must not be less than 7’-0”.

Other:

1. Only equipment used in conjunction with the elevator shall be permitted in the equipment room, pit, and hoistway. No other pipes, ducts, or wiring of any kind that convey gases, liquids, vapours, communication, etc. unrelated to the elevator is permitted per Code.

2. The contractor or owner is to provide a temporary 208V – 30Amp single phase terminal with disconnects for each traction elevator in each machine/equipment room or within 50 feet of machine room for hydraulic elevators at the start of the job for temporary operation of the work platform.

3. Complete connections from the electrical power mains to each controller, including necessary circuit breakers and fused line disconnect switches.

4. 3-Phase electrical power of the same characteristics as the permanent supply without charge for testing and adjusting of elevator.

5. The cutting of walls, floor, etc. and removal of such obstructions as may be necessary for proper installation for the elevator and its components. Setting of anchors and sleeves.

6. Proper trenching and backfilling for any underground piping or conduit.

7. Heat and smoke sensors as required in accordance with latest Fire Code (consult the local authority) and Elevator Code (ASME A17.1) in hoistway, elevator lobbies, and pit.

8. Protection of elevator finishes, including cab, frames, and doors prior to turnover.

9. The contractor or owner is to provide a crane to hoist onto and about the site the equipment required in the hoistway.

10. Building Security system interface is not typically included at time of bid (including wiring through hoistway). Determine prior to order your requirements.

11. Sprinkler systems are not recommended inside the hoistway, pit or equipment room but if provided because of other Codes or building design, then additional requirements for water removal, NEMA rating, power shutdown (shunt trip), etc. is required. Consult the Building Authority and electrical contractor for details. If sprinklers are present in hoistway and equipment room, a means to automatically disconnect the main line and emergency power supply to the elevator prior to the application of water in those areas shall be furnished by the electrical contractor. The means shall not be self resetting.

12. Elevator inspections should be coordinated at the same time as final Electrical, Building, Health, and Fire inspections therefore we recommend this be arranged by the General Contractor/Owner Agent directly following consultation with us. If re-inspections are required due to incomplete work by others, Bermuda Elevator will charge their normal hourly rate for each return visit.
