CFD Hydraulic Modeling Helps Find Solutions to Dam Flow Problems

By Pete Haug, PE Today’s engineering challenges are complex, especially for dam owners and operators. Flow problems around dams include spillway scour, riprap damaging currents, river debris collecting in the wrong places, and uneven overtopping of training walls. Imbalanced flow entering powerhouse units can create trash rack vibrations, excessive bearing wear, and even air-core vortex… Read More »

BIM Delivers Dividends on Unusual Structure Upgrades

By Pete Haug, PE Building information modeling (BIM) can play a big role in keeping the wheels from coming off an intricate project. We’ll look at a case study of a turbine and powerhouse upgrade project where the goal was to minimize changes to the exterior of a historic 1910 dam. But first, here are… Read More »

Material Recycling: A Sustainable Approach to Demolition and Transformation

By Michael Leopold Should a building be demolished? That is a question many owners face when deciding what to do with an existing property. Cost, schedule, and operational impacts are all important considerations. From the perspective of environmental/sustainability considerations, it would be beneficial to reuse whenever possible. The fewer structures that are razed means more… Read More »
