- Description
- This solicitation is hereby amended to respond to technical questions submitted: Vendor questions and answers: 1. Question: The MCU is the master control unit, the MCR is the master control room, as the master location is mentioned, it is assumed this is all the same location as to where all of the conduits end? Where is the Main Control room location on drawing E043? Answer: The Main Control Room is located on the second floor of the Confinement Building. It is not shown on the drawing and NIST will be responsible for running the communications cable between new centralized data collection unit of the Area Monitoring System and the equipment in the Main Control Room (MCR). Cable trays run around the perimeter of the two Guide Halls (original and new). Conduits run down from the trays to the Area Monitoring Detectors in the original Guide Hall or to the location for these units in the new Guide Hall. Drawing E043 shows the location of the existing detectors as well as the recorder rack which serves as the centralized data collection point in the current system. 2. Question: It states that 2 conduits with 4" boxes are provided at each monitor/detector location. DO both Conduits run to the Main Control Room? Answer: No. These conduits run up to the cable trays that run around the perimeter of the new Guide Hall (approximately 6 feet). Nothing runs to the Main Control Room. 3. Question: Will NIST provide duplex 120V outlet and how far away from the detector/monitor? Answer: The Radiation Monitoring System in the existing Guide Hall supplies electrical power to the individual detectors from the centralized recorder rack through the interconnecting cabling. No provisions for electrical power have been provided in the new Guide Hall. If the design requires an ac power source locally at the local Area Monitor Detector, NIST will provide the necessary outlets. Otherwise, NIST will provide electrical power to the centralized location for redistribution through the contractor's interconnecting cabling. 4. Question: If in fact NIST does provide AC power from one of the conduits, is the other conduit available for us to use for our communication line, and does that conduit go to the MCR and MCU? Answer: Most of the cable runs associated with the existing equipment are in cable trays which will be available for use by the vendor supplying the new Area Monitoring System. Similar provisions have been made in the new Guide Hall. These trays run around the perimeter of the Guide Hall, both old and new. Conduits run from the cable trays to the mounting locations for the Area Monitoring System detectors. 5. Question: Contractor's are to supply 2 dry contacts, do you want Normally Closed, or Normally Open, and is NIST responsible to hook up the interlocks to our contacts, as we do not know what they are going to control? Answer: The requirement is for two (2) sets of dry contacts and they are to be Normally Open (NO) contacts - contacts that are open when the armature is in the un-operated or de-energized position. NIST will be responsible for connecting these points into other equipment where appropriate. 6. Question: If in fact the 2 conduits at each location do terminate at the MCR / MCU, is the other conduit able to be used for our network wire? Answer: The connections to the two (2) sets of dry contacts will be the responsibility of NIST. See response above concerning the use of the conduits and cable trays. 7. Question: If the answer is yes to question 6 above, what is the maximum length of conduit from the meter/detector to the MCU/MCR, as 100 meters, or approx 300 feet is about the maximum run we can provide without having to use some kind of a booster? Answer: The cable trays run around the perimeter of the original and new Guide Halls. The dimension of the original guide hall is approximately 200 feet long by 100 feet wide by 50 feet high. The new guide hall is approximately 200 feet long by 80 feet wide by 50 feet high. Cable trays are installed approximately 10-12 feet above finished floor. Conduits only run from the cable trays to the mounting locations of the Area Radiation Monitoring detector. 8. Question: On each conduit, what is the maximum distance from each pullbox to pullbox, or pullbox to termination point? Answer: Refer to response to Question Number 7 above.
