Q (No subject): Will there be a recording for the prebid meeting for those who can not attend?
A: No recording will be made. Contractors are encouraged to attend the pre-bid meeting, however attendance is not mandatory.
Q (No subject): Are you only accepting bids from qualified MBE/DBE/WBE firms?
A: No. The Town will accept all bids from contractors who are able to supply the specified goods and services.
Q (Data Center Uninterruptible Power Supply (UPS) Replacement): I would like to verify that you currently possess the three 20kVA UPS units and that you only need assistance with their installation and removal.
A: The subject project requires the supply of three new UPS units and the replacement of the three existing UPS units. This installation requires the disconnection of existing UPS and re-wiring of new units. All of this work is included in the project specifications.
Q (Please clarify 2.01 - A.): Does the Town of Nantucket need to purchase Three EATON 93PM 120kW UPS units as described in section 2.01 A.
A: The specification of the EATON UPS unit is used for the basis of design. Contractors may submit in their bid three EATON units as specified or three other UPS units from another manufacturer that meets or exceeds the design specifications for the UPS units listed in the project specifications.
Q (2.01 SYSTEM DESCRIPTION AND OPERATION): 1) The description (2.01 – A) is not clear whether they need to purchase 3 Eaton 93PM 120KW UPS. We need clarification if they need to purchase 3 EATON 93PM 120KW UPS? Do they already have the 3 Eaton 93PM 120 KW UPS?
A: Specifications Division Section 263353, PART 2- Paragraph 2.01, subsection A. Reads: 2.01 SYSTEM DESCRIPTION AND OPERATION A. Three UPS units will be required for this project. Manufacturer: The basis of design is the EATON 93PM 120kW UPS. Provide External maintenance by-pass side car as shown on contract documents for UPS#1 and UPS#2. CURRENTLY INSTALLED AND WHICH WILL BE REPLACED are three (3) Mitsubishi 2033C Series 20 kVA UPS units. Each of these units will be REPLACED by a UPS unit that meets or exceeds the design and operational specifications equivalent or exceeding the EATON 93PM 120kW UPS. Massachusetts procurement law generally prohibits specifying a product by only one manufacturer. Alternates may be submitted provided that they meet or exceed the product specified as the basis for design. The successful Bidders to whom the project will be awarded to must supply and completely install three (3) new UPS units in accordance with the project specifications. Bidders must completely remove and dispose of the existing three (3) Mitsubishi 2033C UPS units in accordance with the project specifications. The Town is not independently purchasing three stand-alone UPS units. This project is a complete installation involving electrical wiring and related components as well as the disconnection and connection of the UPS system. This entails that the successful bidder shall SUPPLY and INSTALL three NEW UPS units which are replacing the three existing Mitsubishi units which shall be removed and disposed of.
Q (No subject): From what I’m seeing, the spec appears to be calling for a 120-kW frame size. Is there a specific reason for the preference toward the 120-kW frame versus the smaller 60-kW frame, given the stated load? Understanding the driver here will help us make sure we’re recommending the most appropriate configuration. Also, can you have the customer share a bit more about the environment these units will be installed in? We want to confirm that the room conditions (temperature, humidity, etc.) are within the UPS operating limits and that there aren’t any extreme conditions we should be accounting for.
A: Please refer to the project specifications when preparing items for bid. Specific rationale is immaterial to compliance with the bid specifications. Environmental factors for this installation should be considered to be a standard office environment.
Q (No subject): Just to confirm as well — are all three systems intended to be identical? Our understanding is: • 20 kW load • 15 minutes of runtime at full load • Same configuration applied to each of the three UPS systems
A: Please refer to the project specifications and that this project involves the supply and installation of a UPS unit that meets or exceeds the design and operational specifications equivalent or exceeding the EATON 93PM 120kW UPS. Two UPS units are connected to a battery bank and one UPS unit is stand-alone.
Q (No subject): One other item I noticed on the technical sheet: panelboards are referenced. Can you confirm whether the scope includes an Eaton cabinet for the panelboards, or if the expectation is UPS and battery only?
A: Please refer to the project specifications and that this project involves the supply and installation of a UPS unit that meets or exceeds the design and operational specifications equivalent or exceeding the EATON 93PM 120kW UPS. Existing panelboards are not being replaced.
Q (Drawing Review): 1) The breaker sizes illustrated in the Electrical drawings are 80A, 70, and 60A, all too small for a 20KVA 93PM, which will require a 90A breaker. Please advise.
A: [GGD] UPS #1 is fed from an existing 80A circuit breaker, UPS#2 is fed from an existing 70A circuit breaker and UPS#3 is fed from an existing 80A Circuit breaker. No 60A circuit breakers are utilized. The project intent is to replace the existing UPS units and connect to existing infrastructure. 20KW at 208V, 3phase equates to 55.5A.
Q (Drawing Review): 2) The illustration shows only 2 units with a bypass cabinet; this UPS always requires either a bypass cabinet or a wall-mounted bypass for back-feed protection. Please advise.
A: [GGD] The Eaton 93PM UPS does not include internal backfeed protection on the bypass path. As a result, the system requires a means of preventing backfeed into the bypass source. Provide bypass cabinet on all three UPS units.
Q (Drawing Review): 3) The drawings indicate 20kVA/16kW 93PM, document text indicates a 20kW system. Please clarify that the 93PM is a unity power system with a 20kVA/20kW rating.
A: [GGD] The Specified UPS is a unity power factor with the ability to support .8 leading or .8 lagging without de-rating. Provide 20KW model.
Q (No subject): Follow up on question 9: Unless the breakers are 100 percent rated, in which case we can take 80A @ 208V or 70A @ 220V, we will need a 90A breaker upstream. AC input to the UPS rectifier at full load + battery recharge current for the 93PM is 71A @ 208V, 80A breaker rated at 80% supplies 64A. While UPS is likely not at full load and will run fine off the existing breakers, we cannot guarantee the startup technician will initialize a unit not installed up to specs. We like to hear your feedback.
A: [GGD] I have reviewed the trip curve for the Square D model QO with a trip rating of 70Amperes and 80Amperes and they can hold 100% of their rating indefinitely. 71 amperes will hold for hours. These breakers have had no issues with the existing loads.
Q (No subject): Could you please provide the exact location for the equipment delivery and the installation address?
A: 4 Fairgrounds Road, Nantucket Massachusetts 02554. Lower Level Data Center Lower Level Main Electrical Room Please consult the project drawings for additional information.
Q (Delivery ): Is there a loading dock for delivery?
A: No, but we do have a garage where we can accept deliveries.
