66 -- LINEAR ACCELERATOR SYSTEMS SOL NCI-RFQ-00167-NV DUE 081400 POC Debbie Moore, Purchasing Agent & Todd Cole, Contracting Officer (301) 402-4509 RFQ-NCI-90098-NV for a "Linear Accelerator System," which was issued as a combined synopsis/solicitation in the Commerce Business Daily (CBDNet) on July 14, 2000 and was amended on July 28, 2000 is being amended again in order to answer the following questions from potential offerors: QUESTION 1: Please provide drawings. ANSWER: Drawings were provided to all offerors on the source list. QUESTION 2: Additional clarification of "turnkey" is needed. Who is responsible for required room renovation necessary for equipment installation, i.e. electrical conduit, incoming power changes, water requirements and chilling, floor cutting and concrete work for installation of new base frame, floor tile replace, etc. A site visit will be necessary to fully evaluate the scope of work required. How is this to be arranged? ANSWER: The vendor is responsible for all installation work required to make the machine fully operational. We do not believe the room will require renovation in the classic sense, but electrical and plumbing modifications will be necessary. The vendor is responsible for all electrical service up to and, if necessary, including the wall breaker outside the room. While existing conduit should be sufficient, there is the possibility the vendor will have to provide more. Chilled water is provided to the room, but the necessary plumbing connections to hook it up properly is the responsibility of the vendor. Since the system is a secondary loop system, any control valve will require a bypass (3 way valve) in order to keep the secondary loop pump running properly. The vendor may choose to run off the primary loop of chilled water, but a heat exchanger must be provided which can deal with the amount of sediment inherent in that system. Floor cutting, concrete, work, etc are the vendors responsibility. The floor must be returned to an "as is" or better condition. The Institute does not believe a site visit is necessary for this type of work, nor does it believe the proposed installation is unique. Installation staff familiar with replacing a Varian high energy accelerator with one of its own products should not find that the proposed installation is any more difficult than others. Therefore, a site visit should not be necessary to develop an installation estimate. QUESTION 3: Will NCI provide the appropriate interfaces required for the IMPAC ACCESS system from IMPAC, including modules for interface to the accelerator, MLC, Auto Sequencer and IMRT or are these to be provided by the selected vendor from IMPAC and provided with the equipment bid? The same requirement exists for the EPID interface to the existing system. ANSWER: The vendor will be responsible for making any connections to the record-and-Verify system (IMPAC or whatever the vendor chooses to supply). The NCI will provide the control computer and connection to the local server and currently is licensed to add this equipment into the system. The vendor is required to supply those additional modules, such as sequencer or IMRT, necessary for the accelerator to carry-out its functions. Quotations and all related materials must shall be received in the contracting office by 3:00 PM EDT (local Washington, D.C. time) on August 14, 2000. All submitted quotations shall acknowledge receipt of this amendment. Except for the above clarifications, the July 14, 2000 combined synopsis/solicitation (Submission No. 475011) and July 28, 2000 amendment (Submission No. 479886) remains unchanged.
