Recent Examples of Services We Offer
Port Admin Building & RV Resort - Olympia, WA
Our Geologists, Mr. McCann and Mr. Gean worked with the Port of Olympia to inform the design of a new administration building, RV Resort, and new roadways in and around those sites. QG conducted a geotechnical investigation and environmental site assessment to determine preexisting site conditions, coordinated drilling, test pit digging and provided detailed technical reports providing information about liquefaction, piles, pavement design, stormwater, and sewer construction recommendations for use in and around the Olympia Port Admin building and RV Resort. The project involved frequent communication with local municipalities as well as federal, such as the Department of Ecology, City of Olympia, and County Health.
Tiger Mountain Slope Evaluation - Issaquah, WA
The client for Tiger Mountain proposed building a single-family residence into the slope. The initial building plan proposed building a hillside road throughout the entire slope up to the house, which was to be built in the upper portion of the slope. QG provided a report with recommendations for culverts to be placed where the hillside road would cut through natural outwash areas, slope stabilization for areas where the hill side road would cut into the slope. QG report also provided foundation, drainage, earthworks, erosional control measures, and proper setbacks for the structure. Report recommendations include following local municipal code and the local Critical Area Ordinance.
McLane Creek Piles - Thurston County, WA
QG Staff Geologist was on site at McLane Creek Nature Trail to observe and direct test piling to evaluate axial capacity for supporting new trail improvements across the site. The test pilling was done in order to start the planning process of expanding the nature trails and replacing walk-out observation platforms throughout the trail as well as small foot traffic bridges. Once the test piling was completed, QG used the schematics of the hammer and pile type to provide the client with over all depth for future pilings and the typical capacity for all pilings with necessary safety factor in place.
Birchfield Roadway Evaluation - Onalaska, WA
QG evaluated an existing primitive roadway that was approximately 3600 linear feet in length. The roadway will be servicing approximately 25 future single family residence. Roadway was evaluated by multiple test pits dug to a depth of approximately 5 feet to identify soil layers. QG used a standard T-Probe and a Dynamic Cone Penetrometer (DCP) to evaluate bearing capacity. Soil samples were collected and sent to the lab for testing. Testing included Sieve, hydrometer, cation exchange (CEC) and Loss of Organic thru Ignition (LOI). The results from the DCP and lab analysis were used for recommendations for roadway enhancements, infiltration, and impervious pavement designs.
Mechanically Stabilized Earth Wall - Lacey, WA
QG designed a Mechanically Stabilized Earth (MSE) Wall to support new private roadway construction along a steep slope. QG used information from the geotechnical reports to recommend and design a MSE wall that is approximately 15-feet in height and approximately 100-feet in length. Wall design included specifications on fill foundation properties, seismic data, surcharges, water pressure, external and internal stability, reinforcement layout, and required minimum factors of safety and proper drainage recommendations.
Lincoln Creek - Rochester, WA
Quality Geo was hired by the client to inform the engineering team designing a bridge across the South Fork Lincoln Creek in order to allow access to the western portions of the site for further structural development. Quality Geo conducted a soils investigation including: test pits, soil lab analysis, bearing capacity and stormwater infiltration feasibility evaluation. The main obstacle for this project was the subject parcel ran along Lincoln Creek Road and the South Fork Lincoln Creek intersected the property from the east northeast to the west southwest. The South Fork Lincoln Creek cutoff the most practical piece of land to build on. QG excavated multiple test pits, located between Lincoln Creek Road and South Fork Lincoln Creek. Each test pit was excavated to a depth of approximately 10 feet and soils were classified in the filed according to ASTM D2487. Soil samples were sent to a lab for sieve, hydrometer, cation exchange and loss of organics by ignition analyses. A dynamic Cone Penetrometer was used in the field to assess at what depth a feasible bearing capacity would be reached. Report included recommendations for foundations, earthworks, and stormwater management.
Orchard Park Development - Tacoma, WA
Our Geologists, Mr. McCann and Mr. Gean worked with the Port of Olympia to inform the design of a new administration building, RV Resort, and new roadways in and around those sites. QG conducted a geotechnical investigation and environmental site assessment to determine preexisting site conditions, coordinated drilling, test pit digging and provided detailed technical reports providing information about liquefaction, piles, pavement design, stormwater, and sewer construction recommendations for use in and around the Olympia Port Admin building and RV Resort. The project involved frequent communication with local municipalities as well as federal, such as the Department of Ecology, City of Olympia, and County Health.
