    • 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.

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.

Manchester Annex Superfund Landfill:

  • Clay Cap Integrity Study

manchesterThe Army Corps of Engineers hired Merit Engineering to test the integrity of a clay cap on a superfund landfill in Manchester, WA. The investigation included test borings and soil sampling in the area of concern aimed at determining the moisture content of the subgrade waste materials. With our OSHA Hazardous Materials training, we were equipped to deal with the potentially contaminated samples and any leakage from the landfill that might have occurred during the boring process.

No matter how careful locating services may be, during subsurface exploration or excavation, there is the possibility that an unknown fuel tank or other hazardous material may be encountered. Merit Engineering has the knowledge and expertise to deal with any such circumstances.

Blue Canyon Alluvial Fan:

  • Geological Feasibility Study for a Subdivision on the Alluvial Fan

bluecanMerit Engineering provided geotechnical engineering services for a proposed logging and conversion plan for a 70 acre forest land on the southern end of Lake Whatcom. The site is on a steep sloped hillside with complicated geology characterized by phyllite bedrock. Several landslides have occurred on the inner gorge area of the Blue Canyon Creek. DNR and Whatcom County required a full scale study on the geologic condition with particular interest to slope stability of the hillside and the inner gorge area of the creek, and the effect of logging on slope conditions, safe setback requirement from the bank of the creek. Merit conducted a comprehensive literature review of published papers, geology reports and geologic studies in the area. Merit then conducted a site investigation, mapped all the slope failures and the geometries of potential failure slopes. Merit analyzed the strength properties of the soils and rocks including friction angles and cohesions by back-calculating from the mapped slope failures. Using the strength properties of the rocks and soils, Merit was able to predict the safe slope angle and provided safe setbacks for logging practice and safe design for logging road construction and drainage. The plan prepared according to Merit’s recommendations was approved by both DNR and Whatcom County.

bluecan2Merit Engineering also conducted a geological engineering study of a subdivision of the alluvial fan. The site geology and geomorphology were investigated by visual reconnaissance and subsurface test pits and dynamic cone penetration tests. Recommendations for safe guarding the proposed development were, therefore, derived.

Silver Springs Apartments:

  • Level I Environmental Site Assessment

silver_springsMERIT ENGINEERING conducted a Level I Environmental Site Assessment on a property proposed to be an apartment complex consisting of approximately 250 units in Kent, Washington. The objective of this study was to determine whether the property or the adjacent sites had releases of hazardous substances, pollutants or contaminants. Natural hazards were also investigated by researching relevant geological literature. This study was limited to the research into and evaluation of the existing information documented by others concerning this property and it¡¯s vicinity.

The objective of geotechnical investigation was to study the subsurface soil and groundwater conditions at the proposed project site, derive conclusions, and provide preliminary recommendations for design of foundations to support the proposed structures. Also included in the geotechnical investigation was the design of several retaining walls using geogrid soil reinforcements.

The soils at the site varied greatly and in the three month time it took to complete the earthwork, Merit Engineering provided critical information daily to the contractors. Our responsibility was to insure quality assurance with regards to the earthwork. Many times during the project, Merit was complimented on our knowledge and reliability by the owners, contractors and city officials involved with the project.

Ocean Star Seafood:

  • Hydrologic Study and Monitoring Well Installaions for Wastewater Treatment Plant

ocean2Merit Engineering was retained to investigate the hydrogeologic conditions at the site for an on-site waste water treatment system. Merit conducted a hydrogeological study based on a literature survey and well logs collected by DOE and completed a hydrogeological report including groundwater level, type, flow directions and gradient. Merit also estimated groundwater conductivity and analyzed the extent of the groundwater contamination area based on an analytical groundwater transport theory. With Merit’s report, the waste water treatment system has been approved by the DOE. Merit also provided design service for installation of groundwater monitoring wells system for inspection of the groundwater quality. Merit provided technical support for installation of the wells by providing full observation service guiding the well driller to install the designed wells. Subsequently, Merit prepared a written manual guideline for groundwater monitoring procedures, equipment, quality control and a reporting guide
