DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The current Onan 125 kw emergency generator is over 20 years old and has failed on multiple occasions. This backup generator is the sole source of power for our cave elevators when the power routinely is interrupted. (see photographs at end of document for current system) JECA provides guided tours to over 120,000 visitors a year. The tour route starts nearly

300’ below the surface. At any given moment during operating hours there could be over 50 individuals in the elevators and over 150 people in the cave. When the electrical service is interrupted, the backup generator automatically engages and ensures that visitors will not be entrapped 300’ below the surface or in the elevator shaft. The replacement of the outdated diesel-powered generator and transfer switch with a new propane powered generator and automatic transfer switch of equal capacity will ensure safe and reliable operation for years to come.

1.2 Work Covered by the Contract Documents:

A. Project Location: Jewel Cave National Monument 11149 US Hwy 16 Custer SD 57730

B. Work consists of: Replacing the Onan 125 DGEA, Specification 53643F genset with an equal

125 kw propane fueled generator, automatic transfer switch and load bank. A possible replacement generator that meets these requirements is an Onan Cummins Model: C125N6 propane generator 60 Hz with Load bank Model:OSM1-0100.1-208V33-0600-(4) and automatic transfer switch PowerCommand OTEC transfer switch 40A-1200 A or equal. (See photographs of current specifications at end of the document). All bidders will be required to ensure that the new genset has an equal load bank, specified with automatic battery tending, oil heater and weather Protected Sound Attenuated Enclosure Level 2.

C. To ensure safe operation of the Visitor Center and Elevators during the project the generator will be offline for no more than 7 days. The contractor will coordinate this outage with the COR at least 30 days prior to the outage so tours may be adjusted. The work includes completing all electrical connections to NEC code. The contractor may reuse the existing conduit and wiring if they meet the new generator needs. If not, the contractor will install all necessary conduits and wiring according to NEC code. Propane line installation shall include, but not limited to a buried propane main connection, riser, fully connected and appropriately sized regulator to supply service to the Generator. The generator line connection will not be serviced by the Visitor

Center regulator or riser. The current 2” poly propane line is buried approximately 2’ deep and approximately 10’ from the desired location of the new generator. The contractor is responsible for verifying that the replacement generator and transfer switch will provide the same or more power to the Elevator Operation and the Visitor Center.

D. The current generator, 250-gallon fuel tank, its associated concrete pad, fuel, fuel lines, electrical lines, and bollards will be removed from the premises. All disconnected electrical lines will be properly terminated to NEC specifications. The disturbed areas will be compacted to the surrounding soil strength, graveled with approved by COR ¾ minus road base and compacted.

Disturbed vegetation will be reseeded where necessary with approved seed mixture. The

Page | 4 installation of the new 125Kw generator that has the same capabilities as the old genset will be installed in the same approximate location as the old generator. The onsite work may not take place from May 1 through September 15 due to park requirements. (see photographs at end of document for current system).

E. All work will be performed under a single contract.

F. Period of performance: Work shall be completed within 320 calendar days of the start date provided on the Notice to Proceed.

a. Clarification: The Notice to Proceed will be issued with a period of performance that is all inclusive of supply lead times, material deliveries, decommissioning, installation, anticipated average weather days for location, final commissioning, and acceptance of completed work.
