Solicitation R15PS00433, Amendment 0002 Questions and Answers Question 1. Please confirm the required code for this project? (ex. ANSI 2010) Answer: ASME A17.1 - 2013 Safety Code for Elevators and Escalators Question 2. Please describe the process and cost to receive a confined space permit. Also, outline its valid duration.

Answer: The Contractor will be required to have its own, Reclamation approved safety program that is at least as stringent as the Reclamation Safety and Health Standards. The Contractor’s safety program will have Hazardous Energy Control Program, (Lockout-Tagout) and a Confined Space Entry Program. We do not consider the elevator pits to be permit-required spaces if the dangers are eliminated. For example, as the moving car and counterweight are dangers, the power supply to the elevator hoists would be locked out. At this point we would consider the elevator pit to be a non permit required confined space. A Job Hazard Analysis (JHA) would be performed with all personnel who would be entering the confined space, and the JHA with signatures of each entrant would be posted near the means of ingress/egress. If, however, the Contractor’s Safety Program mandates that all elevator pits are Permit Required Confined Spaces, the Contractor would take the appropriate steps.

Question 3. Section C, Subsection C.1.1.D.1, specifies to rehabilitate the Gearless DC Motor, replace the motor bearings, drive sheave and brake assembly. This is a relatively uncommon request to provide new drive sheave, motor bearings and brake assembly while retaining the machine. Is a “like new” or new machine option acceptable? (Section C.1.18 as well) Answer: Prepare your proposal in accordance with the specifications as written. Failure to comply with the specification may cause the entire proposal to be deemed nonresponsive. Alternative proposals will be accepted for consideration.

Question 4. Section C, Subsection C.1.3.1 specifies The Government will supply cranes and crane operators to unload equipment, materials, etc, in the power plant. Please confirm if this will be provided for the visitor center and will also include setting of machines, drives, controllers and other essential items.

Answer: Reclamation will open and close hatches, lift materials on and off trucks, assist in moving materials and equipment across the power plant from the loading bay to the elevator tower at West end of power plant, and in moving equipment out of the elevator and under the lifting hatch.

Reclamation will make available the facility’s 30-ton boom truck and operator to lift out of or into the Visitor Center elevator room. In case existing or new equipment has to be disassembled to make a safe load, all work will be done by Contractor.

Reclamation will not disassemble, uncouple or do any other demolition work on existing equipment, including any grout pads, floor bolts, etc. that will be removed. Reclamation will not rig any equipment or material for the lifts. Reclamatiohn will not set or install any equipment or do any foundation or floor preparation.

Answer: Badging is usually accomplished during the time interval between Notice to Proceed and the beginning of onsite work. Not all contractor employees will need to be badged.

Question 22. Under Section C.1.3, Item 2 states that the Government will provide five (5) governors manufactured by Payne Industries for the contractor to install, and the sixth governor is to be provided by the contractor. During the walkthrough it sounded like this was going to be 100% confirmed by the facility. Please confirm that the Government will in fact supply the contractor with (5) governors to install. Also, if this is the case, please confirm which elevator the contractor is to provide the sixth governor for, as the equipment can vary between units.

Answer: Section C.1.3 has been changed to correct the number of governors to by supplied by Reclamation. Under the changes the Contractor is to furnish three governors, one each for the Block 8, Block 17 and Power plant elevators. Reclamation will furnish three governors, two for the Visitor Center elevators and one for a Power plant elevator.

Question 23. During the walkthrough, the question was asked about the type of hoistway conduit that is to be used. Please confirm if “rigid” conduit is required in the hoistways. Also, please verify if existing may be retained, if sufficient.

Answer: Conduit in the hoistways is required to be rigid. Existing conduit may be reused, if adequate; however, we do not know the condition of existing conduit.

Question 24. Please confirm if all hoistway switches that are to be installed new are required to be NEMA 1 or NEMA 4 rated.

Answer: NEMA 1 rating is required.

Question 25. Sections C.1.23 & C.1.49 reference a Remote Monitoring System and Maintenance Management System. First, please confirm if these are referencing the same system. If it is, is the Government requesting a single (1) remote monitoring station in a centralized location showing all 6 units, or is the Government looking for a remote monitoring station in each machine room? Second, to my knowledge, I am not aware of a Maintenance Management System that is specified within Section C.1.49 that operates on a Windows 7 platform. Does the Government have any documentation regarding this specific monitoring system?

Answer: As noted above, Section C1.23 has been removed in its entirety. The requirement is that the controllers be capable of performing self monitoring (see the change at Section C1.19), and the separate remote monitoring system is eliminated.

Question 26. Under Section C.1.44, Item A. states all Hoistway Entrance components to be re-used or replaced with new; however, it does not reference the actual hoistway door panels. Item E within this section states “Provide doors with two point suspension sheave type hangers.” Please confirm if this is requesting all new hoistway doors for all 6 elevators (total of 42 sets of hoistway doors).

Answer: Existing hoistway doors will be retained.

Question 27. Section C.1.45, Item C. requests new door protective devices for all elevators, but it does not specify them to be 2D or 3D.

Question 36. Who is responsible for coring holes through the elevator shafts into the elevator lobbies where needed?

Answer: The Contractor.

Question 37. In Section C.1.16.C, MACHINE BEAMS AND OTHER SUPPORT STEEL, it states “Fill and finish all unused holes in machine room, secondary floors and walls, and hoistway to maintain all fire ratings.” Is the contractor responsible for sealing existing penetrations in the elevator shafts, etc.?

Answer: No. The contractor is only responsible for holes which it makes or accidental damage it causes during performance of the contract.

Question 38. Section C.1.22.C.7, identifies “Telephone system tie into the existing phone network.” as a required device in the main car operating panel. Also Section C.1.39 describes additional features of the telephone device. How are the existing brown phones/communication devices in the elevator machine rooms, pit areas and car tops tied onto the existing equipment? Will this same system be retained or replaced, as the scope of work does not mention what is required?

Answer: All telephones are currently connected to the facility telephone system. There is not a separate system for the elevators. The new telephone devices are to be connect to the existing system.

Question 39. Are there any special wiring requirements, spare wires needed for these phones?
