Construction Design

Eric Lindquist, PhD, PE

Chairman of the Board

Moraga, CA

Eric is a nationally recognized geostructural engineer and designer of complex, yet constructable support of excavations systems in challenging ground conditions and urban settings. He completed his Ph.D. dissertation on the strength and deformation properties of mélange (complex rock bodies made up of stronger blocks embedded in a weaker matrix material). His dissertation was nominated for the Rocha Medal, the annual award presented to the top dissertation in the field of rock mechanics in the world. Eric received the 1991 Harry Bolton Seed Award as the top graduate student in the U.C. Berkeley Geotechnical Engineering Department. In 1990 he was one of only six U.C. Berkeley undergraduates awarded a Certificate of Distinction for his academic work.

Charles Luxford, PE, SE, PEng

Director of Engineering

Austin, TX

Charles is Brierley’s Director of Engineering. Charles’ experience with one of North America’s largest and heavy civil contractors enables him to deliver constructable designs for: earth retention systems, cofferdams, falsework & formwork, erection & demolition sequencing, multiple crane lifts, customized rigging, rebar cage handling, access platforms and marine operations. Our contractor clients rely on Charles to solve a wide array of challenges on high profile projects in urban or constrained work sites.

Russell Lutch, PE

Construction Sector Lead

Detroit, MI

Russell’s experience working for one of North America’s largest general contractors has given him hands-on understanding of how contractors implement efficient geo-structural designs. Since joining Brierley Associates, he has brought this knowledge to the delivery of the effective and constructable geotechnical and structural design of deep shafts and tunnels in soil and rock, excavation support systems, cofferdams, shallow and deep foundations, marine construction, and the design of permanent steel and reinforced concrete structures.

Bill Zietlow, PE

Geostructural Consultant

Denver, CO

Bill has worked in geotechnical engineering for more than 25 years and specializes in design of earth support systems for tunnels, shafts, road cuts, and temporary excavations such as soil nail, tieback, sheet pile, soldier pile, and micropile walls. He has also designed deep foundations and landslide stabilizations. He primarily provides design services for specialty contractors on design-build projects but has also provided geotechnical designs for public and private owners, primarily on transportation and utility works. He has design, construction observation, geotechnical investigation, and project management experience on a wide variety of projects and ground conditions across the Western and Midwestern United States. His responsibilities include engineering design, project management, and claim support services. He completed a Master of Science in Geotechnical Engineering at the University of Minnesota.

Eric Michal, PE, SE

Geostructural Engineer

Moraga, CA

Eric has more than 10 years of experience designing excavation shoring, pile foundations, and various contractor support functions including concrete formwork and structure loading. His experience with excavation shoring includes cantilevered, braced, and tied-back piles, soil nail walls, underpinning, and secant pile walls. Pile foundations include design of augercast piles, soil mixing, and micropiles. He is experienced at monitoring construction practices, analyzing field issues, designing and inspecting concrete formwork, and analyzing surcharge loads on both temporary and permanent structures.

Amshu Chappa, PE

Geostructural Engineer

Moraga, CA

Ms. Chappa is experienced in the fields of Civil, Structural and Mechanical Engineering in Heavy Civil. Her experience includes design of excavation shoring, deep foundations and various contractor support functions. Her excavation shoring design experience includes tied-back and internally braced systems using sheet piles, deep-soil mix walls, concrete secant piles, slurry diaphragm walls and soldier piles and lagging. She has also designed soil nail walls and underpinning systems. Deep foundations design experience includes drilled displacement piles, auger cast piles and micropiles. Other design experiences also include the design of temporary bridges and stair tower support systems. Contractor support includes analyzing field concerns and inspecting concrete formwork.

Brent Lindeloff, PE

Trenchless Engineer

Weaverville, NC

Brent has acquired a very broad base of civil engineering experience, focusing primarily on water and wastewater infrastructure. He has developed significant expertise in trenchless construction, planning and design in mid to large diameter water, wastewater, and storm applications. Brent’s interests include horizontal directional drilling, pilot tube guided boring, conventional auger boring, Microtunneling, shield tunneling and tunnel shaft construction and design.

Zach Anderson, PE

Geostructural Engineer

Syracuse, NY

Zach is proficient with design and analysis software such as RISA3D, STAAD.Pro, CivilTech Shoring Suite and CivilTech Allpile and utilizes these to develop efficient designs for a variety of heavy civil works. He has performed analysis and design of support of excavation systems, cofferdams, temporary construction works, reinforced concrete, masonry, timber and steel buildings, shallow and deep foundations and permanent earth retaining structures. He has developed technical specifications for atypical construction such as fiber-reinforced plastic grating and structural shape platforms, concrete mix design for tipping floors, shaft lining, diaphragm slurry walls and flowable fills.
