Cedar Hills Scale & Canopy, King County Solid Waste Division
CivilTech provided structural engineering services to replace in-bound and out-bound scales at Cedar Hills Landfill and to add a canopy at the vehicle maintenance shop. Improvements included raising and/or replacing scale decks, providing new approach slabs, revising a slab on grade, designing wingwalls, and installing bollards. CivilTech also prepared demolition plans for existing structures. The scale replacement was constructed, but King County elected not to replace the canopy at the same time. CivilTech provided construction support services for the scale replacement, which included evaluating the adequacies of the existing footings and piers exposed during construction to support new scale loads, reviewing concrete break test results, preparing sewer pipe detail for sewer line replacement and preparing record drawings.
