3. 1302-1308 Tele-Comm Blueprints.pdf

This document is a comprehensive set of telecommunications infrastructure design drawings and legends for a federal facility. The materials include detailed specifications for the installation of telecommunications systems, underground cable/duct infrastructure, manhole assemblies, and cable tray configurations throughout a multi-floor building complex.

The drawings specify telecommunications grounding requirements, color-coding standards for voice and data wiring systems, and detailed schematics for underground cable routing. Key infrastructure elements include pulling-in iron details, manhole hardware specifications, ductbank section details with 4-inch to 8-inch conduit configurations, and standard electrical trench backfill procedures. The document establishes specifications for cable management systems including overhead cable trays with 12-inch mounting heights, floor-mounted telecommunications cabinets, and raising access floors (RAF). Special attention is given to fiber optic cable installation (72-strand single-mode and 26-strand cables), copper cabling specifications (1200-pair, 600-pair, and 900-pair configurations), and separation requirements between power and communications conduits. The building includes multiple telecommunications spaces across first and second floors, a Communications Equipment Room (CER), and a separate Maintenance and Storage Building with dedicated communications infrastructure. All work must comply with ANSI/EIA standards, and contractor-provided materials and labor are required for complete system installation. The drawings serve as the technical basis for bidders to prepare accurate cost estimates and implementation schedules for the full telecommunications infrastructure build-out.
