This is Addendum #3 to the bidding documents for the 2020 Improvement Projects in Adrian, Michigan, issued by the Lenawee Intermediate School District (LISD) on March 26, 2020, with engineering services provided by Dailey Engineering Inc. The addendum clarifies and modifies the original bidding documents issued March 23, 2020, and becomes an integral part of the project specifications. The projects involve improvements to the LISD Trenton Hills Learning Center and include electrical relocation work, flooring installation totaling 1,361 square feet across two areas, cabinet and countertop modifications with specific finishes (Wilsonart laminate and Karndean design flooring), vinyl base installation, and comprehensive network infrastructure upgrades. Network improvements require the installation of 126 total data drops: 52 new drops at TECH East Building and 74 new drops at Trenton Hills Learning Center, with no changes to TECH Main Building network closets.

The addendum specifies detailed technical requirements for network cabling and equipment, mandating Category 6 plenum-rated UTP and STP wiring throughout with strict installation standards including 6-foot bundling intervals, firewall sealing with Fire Stop red caulk, and EIA/TIA 568B compliance. Network equipment specifications include three Cisco 2960X 48-port switches with corresponding stack kits and cables, three Belkin 48-port Cat6 patch panels, and 126 1-foot blue non-booted Cat6 patch cords. All electrical outlets and raceways affected by cabinet and countertop installations must be relocated or modified to maintain usability in the new configuration, with outlets and raceways raised several inches above countertops. Cable certification testing must be performed using a Fluke DTX1800 tester, with comprehensive labeling requirements for all wiring components. Contractors must include in their bid amounts any cost changes resulting from this addendum.

Network Specifications

Cabling Cabling and connections must be consistent with exiting data cabling and terminations.

The UTP and STP wiring, jacks, patch cables, and patch panels shall be Category 6 plenum rated throughout the entire installation (NO Substitutions allowed without documented written approval).

All cables being run for horizontal distribution within the plenum areas must be bundled together with cable ties every 6 feet, and supported by cable trays, and/or structures attached directly to the building structure/upper decking in the plenum areas or crawl spaces. Where cable trays and conduit is not provided, wiring shall be attached and supported to upper decking by way of J-hooks or bent steel rods installed between decking grooves, or comparable support devices, attached directly to the existing building structure decking or like framework. Wiring will not be supported by ceilings, ceiling hangers, or to existing electrical, plumbing, or air ventilation structures or to existing conduit.

No single Cat6 run shall exceed 100 meters.

Use provided sleeves for all firewall and/or floor interconnects. Seal all wall penetrations with Fire Stop red caulk (MetaCaulk 1000) or other pre-approved fire stop installation.

Wiring must be routed so that it does not interfere with access to panels, switches, valves or other maintenance systems.

The punch down jacks and punch down patch panel cross connects shall be designed so installer will always punch down the cable pairs according to EIA/TIA 568B specifications.

TWISTED PAIRS MUST REMAIN TWISTED TO WITHIN 1/4" OF CONNECTOR. This is required for high-speed data networks.

Wiring will not be installed near fluorescent lighting, high-voltage sources, electrical motors, or other sources of interference. Recommended distances for UTP cabling shall be at least 1 ft. for florescent lighting (unshielded), and 3 ft. for transformers or motors (unshielded). If STP cabling is required, vendor must request in writing to owner.

Splices within cable runs are not acceptable because it may compromise the integrity of the wiring for high-speed data transmission.

Contractors must adhere to manufacturers’ requirements for bending radius and pulling tensions for all cable runs.

All conduits must have bushings at the end of the conduit to prevent cable jacket tears. Where cable is being run from one conduit to another, the cable vendor must insure that twists do not occur during the cable installations as this can cause kinking and tangling of the cabling within the cable run.

After installation is complete, any debris resulting from cable installation must be removed, with the area left as clean as before the installation started.

Raceway The Contractor shall furnish and install; white, metal raceway, wiremold brand cable pathways, Addendum #3 - 2020 Improvement Projects

A3.3 mechanically affixed .

Patch Panel/Cables The Contractor shall furnish and install 48 port patch panels. All cables labeled on the back of each patch panel. Use one 1 foot Cat6 non-booted patch cables, blue in color in the racks in each MFD or IDF rooms.

The wiring components shall consist of jacks, faceplates, wire and all accessories required to properly install the wiring and devices.

Cable Certification Tests and Labeling UTP cable certification must be performed with a Fluke DTX1800 tester. Tests results shall be identified by the corresponding labeled Cable ID and must include wire map, resistance, length, propagation delay, impedance, return loss, attenuation, and cross-talk.

UTP wiring will be labeled on both ends of the outlet, 3 inches back from punch down panel, and 3 inches back from the face plate punch down. Labels for all UTP wiring shall be white, self laminating, adhesive labels.

EXAMPLE: RACK-SHELF-PORT 00-C-27

Cable contractor identification tags shall be attached above conduit stub-up, and at each end of every UTP installation.
