This document summarizes a project by WYCO Construction Services to install a temporary 120-foot self-supporting tower using a Rapid Deployment System (RDS) at a site in Seattle, Washington. The tower was needed to allow wireless carriers to remain operational while an existing structure was modified. The RDS design allowed for rapid construction in just three days and later dismantling with no ground disturbance. It provided a temporary wireless coverage solution using a proprietary ballast foundation system until modifications to the original tower were complete.

1. WYCO Construction Services LLC
4240 East Elwood Street
Phoenix, Arizona 85040
Multiple Carrier Site
Seattle, Washington
120’ Self Supporting Tower
20-Block Concrete Ballast foundation
Rapid Deployment System (RDS)
(WYCO Proprietary - Temp Tower Solution Design)

2. Highlights
• Existing failing structure requires a tower modification for additional capacity needs & 20’ tower-
extension.
• (4) wireless carriers required temporary displacement of equipment along one of Seattle’s busiest
highways.
• Carriers were able to achieve full network deployment of new RFDS with this robust tower design
assisting in better and faster coverage for residents while the existing structure was modified
• Jurisdiction would only approve one temp structure making this a very challenging deployment
• Project location is a critical cellular coverage area, all carriers needed to remain on air during
what was estimated as a 60-day project duration.
• Wyco Field Services & Client design collaboration
• No ground disturbance and no restoration post decomm
• Rapid deployment (total of three days from start to finish in the construction phase

3. Tower & Foundation Data
• Wyco Field Services, project specific foundation &
structural analysis completed and approved with CD’s
through jurisdiction
• Monopole, stealth & self-support structure options can be
utilized
• Loading supports configurations of multiple carriers to
200’+
• Concrete ballast block foundation; multi-use ballast blocks
designed for continued use & transport
• Minimal real estate footprint for compact lease areas in
many cases
• Material & equipment inventory managed by Wyco Field
Services as a value-added service

4. Portable Tower Site Lease Area
• Turn-Key solution, from inception of project through completion – Full Site
Acquisition, A&E & Construction services were completed to get this site
approved to be built
• Wyco Field Services coordinated pre, during, & post construction meetings
with necessary stake-holders; municipality, client, carriers

5. Foundation Base Material
• Native or Non-native base material can be utilized for pad leveling
• Provides level surface for ease of ballast installation

6. Ballast Block Installation
• Pad was built in sloped area by bringing in base rock and completed to
meet compaction requirements in one day
• Provides level surface for ease of ballast installation

7. Ballast Block Installation
• Keyed ballast for ease of installation & securement
• Site area must be level, sand/gravel base is used as top layer to achieve
desired foundation grade and compaction requirements

8. Ballast Block Installation
• Use of hydraulic ram to tighten & secure ballast blocks
• 1.25” diameter tension rods are used to fasten ballast blocks by way of
hydraulic ram-jack

9. Ballast Block Installation
• Final pad surface secured; strong enough to maintain most equipment shelter
enclosures, generators, and other carrier cabinet equipment
• Foundation ready for staged tower

10. Tower Installation
• Tower or pole Installation
• Next Steps; configuration of carrier equipment to be placed on new structure

11. Tower Installation Complete
• Total build time on this project from start to finish, was three days.
• After removal once the structural MOD is complete on existing tower, this site
will be removed and relocated to a new project (Multiple Use)
• Upon removal of this temp structure, the site will go back to original condition
after cleanup, requiring no restoration saving money at the decomm phase
