Project Experience <br />Watermains N, O, Q, TU V & W Replacements – Everett, WA <br />Client: City of Everett – Amie Roshak PE, PMP <br />These projects involved subsurface investigations and geotechnical engineering recommendations for <br />replacement of aging water mains. Krazan provided geotechnical engineering investigations to evaluate the <br />subsurface soil and groundwater conditions at these sites; a review of available geotechnical reports pertaining <br />to subsurface soil and groundwater conditions in the general site area; laboratory testing; recommendations for <br />earthwork and site preparation including the suitability of on-site soils for trench backfill, placement and <br />compaction of on-site soils, the mitigation of unsuitable soil conditions, and an evaluation of weather sensitivity <br />during construction; recommendations for conventional trenching techniques, excavation, pipe support, erosion <br />control during construction, and construction dewatering considerations; and recommendations for seismic <br />design considerations including site coefficient and ground acceleration information. <br />Maywood Hills Elementary School - Bothell, WA <br />Reference: Northshore School District - Ngan-Ha Yang, P.E. - nyang@nsd.org, Tel: 425-408-7858 <br />This project involves major building additions to the existing Maywood Hills Elementary School. Our team <br />members coordinated two phases of site investigation. Phase I involved exploratory soil borings and a <br />preliminary Geotech report for the site. When the design team elected to re-locate the planned new building, <br />Krazan conducted a Phase II investigation, with additional borings and prepared a Phase II geotechnical <br />engineering report, with the results of the subsurface explorations, exploratory boring logs, a site plan, and <br />interpretations of fill / native soil stratification across the planned building area. The report also included <br />groundwater observations, geologic and seismic hazards, and recommendations for foundations, retaining walls, <br />shoring walls, and pavement design. <br />16th Avenue SW Pedestrian Safety & Traffic Calming - White Center, WA <br />Reference: King County - Linda Mott - linda.mott@kingcounty.gov, Tel: 206-477-3669 <br />King County contracted Krazan to determine pavement thickness, soil types, and environmental contaminant <br />levels within the soils at two boring locations within the right-of-way of 16th Avenue Southwest in White Center, <br />WA.. The Krazan team examined the soils and geologic conditions encountered, obtained samples of the <br />different soil types for soil classification and environmental testing, and maintained logs of the explorations. <br />Samples from the soil borings were collected continuously, resulting in a full soil stratification profile to the <br />depths explored. <br />Bothell High School Modular Classrooms - Bothell, WA <br />Reference: Northshore School District - Devlin Piplic - dpiplic@nsd.org, Tel: 425-408-7816 <br />This involved removal of existing portable classrooms, and installation of a new modular building. Krazan was <br />contracted for stormwater infiltration testing. Then we were contracted to provided earthwork <br />recommendations for the new building. We conducted a site investigation involving two (2) exploratory soil <br />borings. Our team prepared a geotechnical engineering report detailing geologic hazards, and recommendations <br />for site preparation, temporary excavations, structural fill, foundations, lateral earth pressures for retaining <br />walls, site drainage and landscaping.
