Jeff Wale

Jeff R. Wale PE, CESCL
Senior Project Engineer

Jeff is a Licensed Engineer with over 14 years of professional geotechnical engineering experience in Washington State and a Certified Erosion and Sediment Control Lead (CESCL). He performs a wide range of geotechnical services, including: site inspection; mechanically stabilized earth (MSE) and gravity wall design; in situ treatments to improve soil characteristics; earthworks plan review; and deep foundation support such as driven pipe, helical anchor, and auger cast pile designs. He has evaluated slope stability for commercial structures and municipal properties, assessed buoyant forces on below water table structures, and evaluated hydraulic forces causing stream scour.

John AndersonJohn H. Anderson PE, CESCL
Project Engineer

John is an Engineer-in-Training in Washington State and a licensed Certified Erosion and Sediment Control Lead (CESCL). As a geotechnical engineering intern with Seattle Public Utilities, he gained a wide range of experience with permitting, field reconnaissance, laboratory testing, and contractor coordination. John’s work in the construction industry provided complementary hands-on experience with foundation reinforcements, drainage, and the interpretation of building drawings and specifications. He performs a wide array of geotechnical investigations and reconnaissance (test pits, borings, subgrade evaluations) as well as in situ (nuclear densometer testing, dynamic cone penetrometer) and laboratory testing (Proctor compaction, sieve analysis, Atterberg limits, moisture density, etc.) of soil.
