Aberdeen Lake Dam Upgrades

The Aberdeen Lake Dam is an earthen dam originally built around 1908 and modified in 1964. It needed repairs and modifications for long-term safety and operational efficiency. The project, for the Regional District of North Okanagan, involved partial removal and replacement of the existing dam, replacement of the low-level outlet pipe, and installation of a new vertical gate with a gate chamber and access shaft. Everything had to support a potential future 5-meter rise in reservoir water level.

Piedmont Atlanta Hospital Marcus Tower

950,000 sq ft | $450 million | 16 stories | Completed in 2020 Structural Features:This major expansion to the Piedmont Atlanta Hospital campus houses critical and acute care patient beds, laboratories, and surgery centers.The signature curved geometry of the building was achieved using post-tensioned concrete framing.Tower columns could not continue through the large open ground floor lobby, resulting in the need for a system of massive 10-foot deep post-tensioned transfer girders above.Special measures were undertaken to accommodate the tie-in to multiple adjacent buildings.The sloping site and variable subgrade conditions resulted in significant earth retention challenges and also the need for multiple foundation types.

Amli Arts Center

Structural Features Planted landscaping, a structured pool, sundeck, and other luxury amenities are supported on the top level of the parking deck. Tower floors typically consist of 7-1/2″ thick post-tensioned flat slabs which minimizes structural depth and allows for reduced overall building height. This provides significant savings on building skin costs, while still allowing for luxury features such as 10 foot ceiling heights and floor-to-ceiling windows. The concrete flat slab also allows for the slab soffit to serve as the ceiling in many locations, which provides additional savings. The multi-story pedestrian bridge is constructed using concrete-framed structure. This allowed the bridge to be constructed efficiently and simultaneously with the tower.
