Glenwood Springs - Colorado Mountain College

 RFP 495‐11 Telecom Cabling – Glenwood Springs Addendum 001 Issued 03‐21‐2011 Scope of Work: 1. Overview a. GENERAL The purpose of the telecommunications cabling standards is to insure the highest level of performance, while allowing for the easy migration of emerging technologies within the CMC infrastructure. b. SCOPE OF WORK 802 Grand Avenue is approximately 40,000 square feet, 30,000 of which falls within the scope of this RFP. The building is two parts, an original structure of three stories and a new structure of three stories plus a basement. MDF will be in the “new” basement and five IDF’s will be on the “old” 2nd and 3rd floors plus the “new” 1st, 2nd, and 3rd floors. Generally, work will consist of fiber optic pulls from MDF to each IDF, and copper pulls from IDF to work spaces. Most of the latter can be accomplished in the space above suspended ceilings. The work will be incremental by stages as areas and offices are prepared for occupation by departments or groups. It is CMC’s intent to prepare large suites and areas served by a single IDF rather than individual offices. c. CONTRACTOR/SUB CONTRACTOR i. Contractors must be licensed and bonded and must have a minimum of five years of experience in the installation and maintenance of the system equipment specified, including supporting materials and equipment. March 21, 2011 ii. The Contractor/installer shall insure that telecommunications cable is installed with care, using techniques which prevent kinking, sharp bends, scraping, over tightening of tie wraps, cutting, or deforming the jacket, or other damage. During inspection by the College or its designee, evidence of such damage will result in the material being declared unacceptable. The Contractor shall replace unacceptable cable at no additional expense to the College. d. WARRANTY i. Colorado Mountain College requires a minimum of a 15‐year manufacturer’s warranty covering telecommunications passive infrastructure products for all new installations. The warranty will include labor and materials for the installation, as well as, an applications assurance clause. 2. Infrastructure Standards a. INTRA‐BUILDING CONNECTIVITY i. Intra‐building connectivity, closet to closet, will be supplied by means of fiber optic cable. This fiber cable shall be 62.5/125 m multimode with a minimum 12 strands. If single mode is needed in the installation, the installation shall be a 8.3‐9/125 m single mode, with a minimum of 12 strands. Transmission capacity shall not be less than 500 MHz on any installed fiber ii. All intra‐building fiber shall be installed in a minimum of 1 inch interdict between closets. Intra‐building copper shall be installed in conduit of adequate size, or otherwise protected from damage and wear. iii. Each intra‐building fiber optic cable shall be fitted with a fan‐out assembly prior to termination. The contractor shall use a fan‐out assembly recommended by the cable manufacturer. All fiber optic strands shall be terminated with LC type connectors. The terminations shall meet all applicable standards and be finished in a manner to best assure longevity and reliability. March 21, 2011 iv. Intra‐building fiber optic runs shall be pulled only from an MDF location, to an IDF. IDF to IDF trunks will not be permitted. b. INTERMEDIATE DISTRIBUTION i. Edge port distribution shall be a minimum of Category 6 from the distribution frame to the communications outlet ii. Category 6 cable shall be plenum rated throughout and shielded where needed. This will be evaluated by the Network Service team prior to installation iii. All communications outlet shall be rated for minimum Category 6 specifications iv. All cables, other than those in the Telecommunication Closets at the terminal backboard shall utilize conduit, support rings, cable tray/ladder, or acceptable equivalent when being routed through the building. v. All horizontal support outside of a cable tray shall route parallel and perpendicular to building walls. Routing will follow the hallways, not be routed through classroom or office ceilings. Optional routing of horizontal cable shall not be permitted without prior approval from the college or its designee. vi. All bend radius and pulling tensions must comply with EIA/TIA‐568‐B. vii. Cable bundles shall contain no more than 50 cables at any support point; plenum tie wraps utilized to secure cables shall not damage the cable jacket. viii. The length of each cable shall not exceed 90 meters. ix. Horizontal wiring shall be star‐wired from the telecommunications closet to each work area outlet, with no intermediate connections. x. Cables shall not be spliced or taped. xi. There shall be adequate slack wire between the Category 6 jack and the wall surface of the outlet box to allow for future repeat termination. xii. The contractor shall leave a minimum 10 foot service loop in each horizontal cable neatly coiled in the ceiling area. xiii. Cable bend radii shall be observed for any work area service coils. xiv. The contractor shall terminate the 4 pair cable according to the manufactures recommended practices. xv. The cable jacket shall be maintained as close as practicable to the point of termination and pair twists shall be maintained to within ½” of the pair termination. March 21, 2011 3. FIBER OPTIC PATCH PANELS a. All terminated fiber strands shall be housed in a fiber optic patch panel. The fiber panels shall be sized based upon the number of strands being terminated plus 25% for growth. b. The fiber panels shall be capable of being rack mounted in a standard 19” equipment frame. c. Each fiber optic panel installed shall be fully loaded with duplex LC coupling modules. d. Each connection shall be labeled with the remote termination data. March 21, 2011 4. WORK AREA OUTLETS a. The quantity and location of the work area outlets will be as defined in the plans. b. The voice/data outlets shall be mounted at 18” above the finish floor and all wall phone data outlets shall be mounted at 56” above finish floor. c. The faceplates at each work area shall be either a single gang or double gang plate depending on the outlet type. i. Each faceplate shall be equipped with ACO unshielded cable installation with 110 edge connector kits. ii. All faceplates and components shall be ivory or white in color. iii. Every port will be labeled in a manner consistent with the patch panel ports. d. The voice and data ports at each outlet shall utilize ACO inserts. i. Each data insert shall be a single 8‐position category 6 minimum jack with T568B wiring. 5. COMMUNICATIONS CLOSETS a. Equipment racks in each closet shall have at least 36” around the front and back of all racks. i. All equipment racks shall be freestanding 19”x 84” (or appropriately sized wall‐mount racks) with EIA 5/8”‐
5/8”‐1/2” hole patterns along each side of the vertical rails. ii. All cable will terminated at 45‐degree angled patch panels mounted in the appropriate two‐post racks. All patch panels and ports will be labeled in a manner consistent with the work area outlets. iii. Equipment racks will be securely mounted to the floor or wall using the appropriate anchors. b. Install 9” minimum width telecom runway above any freestanding rack and backboard with a section connecting the two. i.
