Retaining Wall Design

  • Similk Bay:
  • City of Blaine:
    • Design of a 400′ long geogrid reinforced retaining wall- Merit Engineering conducted geotechnical engineering investigation for about 500 feet of bike path on Washington State Department of Transportation (WSDOT) Interstate Highway 5 Right-Of-Way. Merit provided engineering design and specification for construction of a geogrid retaining wall. The design has been reviewed by WSDOT and approved for construction. Parallel with this retaining wall, Merit provided full geotechnical services for 5,000 feet of 3rd street reconstruction including pavement section design, subsurface conditions and evaluation of the existing road conditions.

Underground Utility Design

  • Western Washington University:
    • Underground tunnel for a communication project
  • City of Bellingham:
    • About 2,000 linear foot Yew Street sewer extension project

Foundations

Slope Stability

  • Point Whitehorn:
    • Slope stability investigation for 15 acre site on Point Whitehorn- MERIT ENGINEERING was hired to perform a slope investigation of the subject property. The subject property is about a 15 acre site on Point Whitehorn. The sea cliff was about 50 feet high and had a history of numerous landslides. Whatcom County Planning Department required that a comprehensive geotechnical, geological, and hydrogeologic study be completed so that the new development will not contribute to the problematic area, especially causing an influx of water to the already troubled residences on the bluff. Merit conducted a geological, geotechnical, and hydrogeological investigation on the Point Whitehorn area, including literature review, test borings and test pits, monitoring well installation and inspections. Merit Engineering was able to derive the geology settings of the area, soil and groundwater conditions based on the results from test borings and monitoring wells. Merit then evaluated the stability of the sea cliff and the effect of the recession of the cliff on the proposed project. We provided recommendations for site drainage and bearing capacity for buildings. The plan using Merit’s report and recommendations has been approved by Whatcom County and is under construction.
