How to turn a 90m ski jump at the Calgary Olympic Park into a cell tower?

Solution
The height and location of the Calgary Olympic Park 90m ski jump provided a great structure for the cellular coverage of western Calgary, AB. Mounting the antennas to the concrete structure was quite simple. The challenging part was locating the equipment. No ground space was available for the shelter and the few floors in the ski jump were occupied.

The main section of the tower forms a hollow concrete column with a staircase on one side and an elevator shaft on the other. After careful consideration, a completely enclosed mezzanine was engineered in the tower to house the cellular equipment.

The design minimized the aesthetic impact to the picturesque surrounding area, while cost-effectively locating the equipment near the antennas.

How to overcome little or no ground space when designing a site?

Solution
This busy interchange near Vancouver, BC was a dead spot for one carrier's cellular coverage. The only reasonable location for the needed cell site was at the edge of a golf course property near the interchange. This location proved challenging as it was right on the embankment of the existing highway.

A concrete lock-block retaining wall was engineered to allow for the safe installation of the shelter and monopole. The wall was engineered to retain the soil with the increased surcharge of the vehicle load on the highway. The final result was a cell site neatly tucked into the bank of the highway.

How to bring sufficient power to a rooftop shelter installation?

Solution
TRK was retained to engineer a rooftop cellular installation on this high-rise apartment building. The antennas were wall-mounted to the exterior of the penthouse. The building's structure was carefully reviewed to determine a suitable location for the 40,000lbs. shelter. The shelter was located over two shear walls near the penthouse- mounted antennas.

A sufficient power supply for the shelter was only available from the ground floor of the building. It would have been quite costly to core and route a new feeder through all floors of the building to obtain the necessary power. Instead, the capacity of an existing feeder to the penthouse was increased by the installation of step-up and step-down transformers at the main floor and roof respectively.

Though the rooftop installation described above is quite typical, the details in the engineering saved the client time and money. TRK makes the commitment and takes the time to search for unique and practical solutions.
