I I Geotechnical Report Mountainview Business Center - Lots 3, 4, and 5 IIndustry Street and Associated Boulevard Everett, Washington I i 1.0 PROJEC'T DES�RIPTIO\ IThe project site is compriscd oFLots 3,4, and 5 in the Mountaiuview Business Center. �Ve were provided witlt a conceptual site plan for Lot S showing construction of an approximatcly 40,000 square-foot, single-story Iwarehouse building with an adjoining office area. A 2,000 square-foot mezzanine level will be constructed over thc office in the nottht��est comcr of d�e building. Loading docks and a ramp into the building will be bcated � along ti�e west side of the building, with parking provided along the north and �vest sides. f�ccess to Lot 5 ��ill be I off Industry Street at the lot's northwesl corner. D[ain level building iloor slabs will Ue constructed at Elev. 42�.00. Site grading will consist of wts and fills up to six feet in depth to achieve planned finish grades. The ! planned development nn Lots 3 and 4 is unknown at this timc. It is our understanding that similar structures will � be constructed on these lots in the future. I We espect building construction �vill consist of perimeter pre-cast concrete tilt-up wall panels, «�ith interior isofated columns supporting tlic roof strucwre. Specific building loads �vere not provided. However, based on our experience with similar building design, structural loads will likely bc 6 to 8 kips per lineal foot for perimcter ( walls, und RO to 100 kips for interior isolated columns. Nominal Iloor slab ]oadino in thc range of 250 to 300 powtds per square foot (ps� is likely. VJe expect die loading dock �valls will be designed as retaining walls aprroaching hcights of four fcet. I Tlie recommcndations cantained in the Collowing sections of this report are based on our understanding of the project design Ceatures as discussed nbuve. Wc sho�ld review project civil and structural drawings as they I becomc available in order to supplement or amend our recommendations, if required. I � 2.0 SCOPE OF 1VORK Our work �vas completed in accordance �vith our authorized proposal dated November 22, 2004. Accordingly, on January 13, 2005, we excavated 10 test pits to a maximmn depth of 1 l5 fcet below esisting surface grades. Using the ini'ormation oUtained Crom the subsurface exploration, we performed analyses to develop geotcchnical � recommendations for project design and constn�ction. Specifically, diis report addresses the fullowing: • Soil and groundwatcr conditions ' • Seismic/liquefaction • Site preparation and grading � • Gxcavation • 1=otmdations ; �� �
