Blue Ridge Hotshots Fiber Optic Install, Coconino NF

BLUE RIDGE HOTSHOTS FIBER OPTIC DIVISION 1 GENERAL SUMMARY OF WORK – 011100 PART 1 - GENERAL Scope of Work The Contractor shall be responsible for furnishing all labor, equipment, transportation, and specified materials/supplies necessary to complete the installation of aproximatly 1,500 lineal feet of single mode (SM) fiber optic cable (6 strand pairs running to each building; 12 stand pairs total) providing for an outside plant (OSP) fiber optic backbone between three (3) buildings located on the project site. Fiber optic cable penetrations into each building shall be installed with wall mounted NEMA enclosures on the building exterior and terminated in a wall mounted NEMA enclosure with cooling fan, uninteruptable power supply (UPS), and fiber adapter panel in building interior. All fiber optic strands shall be terminated on a fiber adapter panel with duplex LC connectors in the interior NEMA enclosure. All new fiber optic strands shall be tested to industry standards and shall meet minimal requierments. Optional work includes the installation of dedicated 15 amp electrical circuits, each with a quadplex 20amp 120v recepticle installed near the new interior NEMA enclosures, and the testing of existing fiber optic cable. The existing fiber optic cable (SM; 24 strands) shall be tested to industry standards. Background The Blue Ridge Ranger Station is a remote facility on the Coconino National Forest. The ranger station is the main hub for operations on the ranger district. The facility is host to office space, residential buildings, and wearhouse space. The station is located in a dense ponderosa pine forest, and mostly flat, rocky terrain. Office Buildings, living quarters, and operations facilities are located on the ranger station; with wet and dry utilities that service most buildings. Users located on this facility have historically experienced a substandard level of service with regards to telecomunications and internet bandwith. This low level of service limits the telecoms capacity and reliability for the workforce on-site. The existing telecom infrustructure is in need of upgrades before the network can be improved. 1.3 - Location All work items contained in this contract will be located at the Blue Ridge Ranger Station in the Coconino National Forest, near Happy Jack, AZ: Blue Ridge Ranger Station: Address: 8738 Ranger Road Happy Jack, AZ 86024 Directions: From Flagstaff, Arizona, take Lake Mary Road (CR-3) southbound for 53.6 miles. At the Junction of Lake Mary Road (CR-3) and AZ-87, Turn Left (to the East) and travel for 9.1 miles. Blue Ridge Ranger Station will be located on the right side of the road (south side). 1.4 Work Description: BASE ITEMS Fiber Optic Cable Approximately 1,500 lineal feet of SM (OS2) loose tube fiber optic cable shall be installed as a fiberoptic backbone. Fiber optic cable shall be rated for OSP use and appropriately rated for the installed application 12 fiber optic strands (6 strand pairs) shall be run between the recreation modular building and the maintenance building (refer to site schematic) 12 fiber optic strands (6 strand pairs) shall be run between the recreation modular building and the hot shot building (refer to site schematic) The suggested alignment for the proposed fiber optic cable backbone is shown on the Site Schematic, included in this document. However, the contractor is responsible for choosing the final alignment that is cost effective, low impact, and provides the required infrastructure; as specified in this contract. Proposed alignment must be approved by contracting officer’s representative (COR) prior to construction. There will be no adjustment of payment to the contractor based on deviations to the proposed alignment shown in this document. Fiber optic cable may be installed utilizing aerial, ducted, and/or direct burial methods. Contractor is responsible for avoiding and resolving any conflicts with existing site utilities (existing utility plans provided in this contract). All existing trees shall remain undisturbed, fiber optic cable shall not encroach within any existing tree drip line. Contractor must receive permission for installation of fiber optic cable on any utility owned infrastructure, existing government-owned poles may be used if all design and technical recommendations/requirements can be met. Use of existing government owned poles must be approved by COR in writing. Minimum allowable vertical clearance between new aerial fiber optic and existing grade shall be 18 feet. When fiber optic cable crosses a roadway, the fiber optic cable shall be aligned within 10 degrees perpendicular (normal) to the roadway centerline. Aerial fiber optic cables shall be installed in accordance with NESC guidelines All Poles, cables, strands, masts and appurtenances installed by contractor shall be rated for the designed application. All Poles, cables, and appurtenances installed by contractor shall have a horizontal separation of 20 feet from existing utilities unless otherwise approved by COR. Load calculations for all components (including cable, messenger, support and attachment hardware, poles, crossarms, structures, and braces) of the aerial cable system shall be provided to COR prior to construction. Aerial cable system shall conform to all load and strength requirements of the NESC guidelines. At/below grade installations shall utilize trenching and excavation methods. All trenches must be uniform in width. Trenchless methods may be utilized for short distances (e.g. roadway crossings), all instances of trenchless construction must be approved by COR. Contractor shall review existing utility plans (provided in this contract) for potential utility conflicts. Underground installations must be installed with a minimum of 18 inches and a maximum of 36 inches of cover, measured from the top of the cable or duct to …
