The Williams Transmission Tower located adjacent to Oak Street at Miami University in Oxford, OH is approximately 342' tall including the former 54’ WPTO transmission antenna atop the 288’ self-supporting tri-leg tower.

Project Scope –

1. Deconstruction and disposal of the Williams Transmission Tower to include any/all attached antennas, cables, and devices, ice bridges (2) and their associated/attached cables to the point of ice bridge connection to Williams Hall. The tower top beacon and hazard lights are to be salvaged and turned over to MU. The concrete bases/piers at the junction to the tower structure and the surrounding fence will remain. All other removed materials are to be properly disposed by the contractor.

2. Power pole adjacent to Oak Street and associated meter housings, enclosures, etc., pull any remaining wire, cut/cap conduit(s) 2’ below grade feeding distribution panel adjacent/outside to tower fence enclosure post Duke disconnection at head). two breaker panels inside the fenced area. These two panels to remain. Remove and dispose of the pole, back fill/compact hole, topsoil, and sod disturbed area. Overhead feed to the pole was removed 11/2/20.

3. Transmission distribution panel/generator hookup and associated poles/concrete bases (3) adjacent to tower fenced area to be removed and disposed. Underground feed to be pulled from conduit to power pole and conduits (3) into fenced area to be cut/capped 2’ below grade. Back fill/compact holes, topsoil, and sod disturbed area.

4. Remove and dispose of (3) Satellite dishes and their mounting supports to the concrete bases. The bases to remain.

5. Remove electric feed and associated conduit from Williams Hall wall to tower lights; patch wall penetration and paint to match existing exterior wall. Remove electric feed to satellite dish on west side of Williams Hall patch wall penetration and paint to match existing exterior wall.

6. Remove (cut flush with ground) and dispose of the red I-Beam support structure adjacent to the building chiller condensing unit and its walkway.

7. Remove and dispose of the round transmission waveguide and its mounting brackets attached to Williams Hall. Cable traverses from the transmission building to the ice bridge (runs west to east on the south side Williams Hall). Patch bracket mounting holes and paint to match existing wall color.

8. Patch the panel beneath the ice bridge where the former cables penetrated Williams Hall – details to be provided in addendum 2.

It is anticipated that tower deconstruction will use the lots adjacent and West of Williams Hall - the pick point being about due South from the location of the outside chiller (in the picture). Build boom to the West. Ideally, Oak street (other than the parking spots adjacent the building) is not impacted. The parking lots and traffic in these lots would be closed to support deconstruction. Contractor to provide flaggers to coordinate traffic control when entering/leaving. If traffic on Oak Street is impacted or road closure required – contractor is responsible for any costs associated/permit filing etc.

The contractor is responsible for providing a temporary construction fence to enclose the working area (laydown, ground demolition, truck loading, etc).

The contractor is responsible for protecting existing hardscape/landscape, buildings, and infrastructure during the deconstruction, dismantling, and disposal. As above, scrap is the responsibility of the demo contractor to remove and properly dispose off-site.

The contractor is responsible to provide and maintain a temporary restroom facility (Port-o-let) for their personnel’ use during the project.

Schedule - start no earlier than 11/30/20 and no later than 12/7/20. The University anticipates the job completion requires less than ten days. The majority of students will be off campus for the long holiday break. Staff, faculty, and students in Williams Hall will relocate and the building unoccupied/locked while the tower is being deconstructed and/or while the crane is vertical. Substantial completion required by 12/24/20.

Additional information:

Lead Paint - Due to the age of the structure (constructed prior to 1978) the contractor should assume that painted surfaces contain some amount of lead. The contractor should follow the OSHA standards to control lead exposure during demolition unless they take paint samples that show the paint to be free of lead. Means and methods (e.g. torch cutting) the contractor plans on using to demolish the structure will determine if testing of the paint is needed.

OEPA notifications for Demo/Reno jobs in Ohio – contractor responsibility to obtain permit and ensure notification is made and appropriate waiting period complete prior to commencing deconstruction. The following information is provided based on Miami EHSO input “visible review of the Antenna to see if anything that would be suspect material and after looking at the structure itself (steel), the base (concrete), the various items attached (steel/aluminum/fiberglass), and lastly the electrical/communication wiring coming from the building and running up the tower itself.  The structure and items I just listed would not be something I would sample as a licensed Asbestos Hazard Evaluation Specialist due to their composition.  That being said, if, during the demolition process, the contractor doing the work would become aware of or suspicious of a material I did not list above, we would want to make sure we stop the work and re-evaluate to see if we needed to sample any hidden or suspect material. My OEPA Asbestos Hazard Evaluation Specialist Certification Number is: ES35993 and if your contractor requires a more formal report/recommendation that the above information please let me know and we can work on providing them what they require.”
