Attachment S Tower Loading - Monopole - Cumberland.pdf

This is a tower loading specification document for a communications monopole tower project in Cumberland, Maryland, submitted by the Maryland Department of Information Technology (DoIT). The document outlines the structural design requirements for a 185-foot monopole tower, specifying antenna mounting locations and configurations across multiple elevation levels. The design accommodates nine antenna systems distributed across the tower structure, including one lightning rod at 200 feet, three CC807-11 BOG6 antennas with collar mounts at the 180-165 foot elevation, two 6-foot HP Dish R5 antennas with collar mounts at the 150-145 foot level, and six WPA-700102-8CF-3-25-850 PSA6 antennas with collar mounts positioned at the 125-100 foot and 100-75 foot elevations. The design mandates that cables be routed inside the monopole with cable ports positioned below proposed antenna elevations to maintain structural integrity. The tower and foundation structure must incorporate 50 percent additional design capacity beyond calculated loads, and the document notes consideration for additional antennas in the structural design calculations.

The tower loading specification is part of a larger procurement package for the Cumberland Communications Facility, with proposals due August 21, 2026, at 12:00 PM via electronic submission through eMMA. A mandatory pre-proposal site visit was scheduled for July 16, 2026, at 11:00 AM at 600 Bishop Walsh Road, Cumberland, Maryland. The contract is subject to a 3 percent Minority Business Enterprise (MBE) subcontracting goal and Maryland prevailing wage requirements, as the contract value exceeds $500,000.
