8th Annual Kickball Without Borders Fundraiser

img_20160820_103456A few GRI kickball enthusiasts took part in the 8th annual Engineers Without Borders (EWB) fundraiser.  It was a blistering hot day, and each team brought their top competitors.  GRI took the field first and was able to hold back the opponent the first few innings, but after several scoring runs we lost the first game.  After a small break, GRI was back on the field facing off against a new team.  Every inning we seemed to be evenly matched, and after a few controversial plays the other team eventually pulled ahead.  Now 0-2 we had one more game to restore our honor.  There was no way we could walk away without a win and it was time to take the field for the last time.  Third time is a charm, because we dominated our third game.  Unfortunately, we did not qualify to make it to the next round…but there is always next year.

GRI is a big advocate of the EWB organization and was one of the sponsors for the event.  The GRI team captain, Kyle Wolfe, also regularly volunteers for the organization.  Currently he is the Responsible Engineer-in-Charge for the Honduras Program.  Thanks to the contributions of all the sponsors EWB was able to raise $20,500, which will be distributed between the active EWB projects.

Groundbreaking at the Vancouver Waterfront Park !

test-2The ground breaking ceremony of the Vancouver Waterfront Park – Grant Street Pier took place on July 18, 2016, and commenced Phase I of park construction for this project, which has been in the making for more than 10 years. The renovations will reconnect downtown Vancouver to the Columbia River and inspire a new vivacity in the Vancouver Community.

GRI’s Washington office, located in downtown Vancouver, has taken an active role in the development stages of the project and is excited to provide geotechnical support to an innovative transformation of the Vancouver Waterfront.  GRI conducted the geotechnical investigation for the Grant Street Pier and core park improvements, which include a large plaza, viewing platforms, and riverfront access.  This investigation included review of available geotechnical information for the site; subsurface explorations; laboratory testing; and engineering analysis for the planned pier, walls, and other improvements.  GRI is currently providing construction engineering services to support construction of the Grant Street Pier foundations.

The planned location of the 7.3-acre Vancouver Waterfront Park is on the north bank of the Columbia River in downtown Vancouver at the site of a previous Boise-Cascade paper finishing plant.  The park will be approximately 2,300 ft long, will extend about 250 ft north of the river, and is scheduled to open to the public in 2017.

This past weekend GRI employees and family members participated in the SOLVE IT for Earth Day Event at Tryon Creek State Park.  GRI worked with several other community volunteers and pulled out non-native English Ivy from surrounding native vegetation. Together with 7,000 volunteers across the state of Oregon we cleared 12 acres of non-native invasive plants from 170 parks, waterways, neighborhoods, and natural areas!

English ivy has become a major issue for Pacific Northwest Forests and Parks.  This past Saturday GRI got a first-hand look at the invasive plant species.  Thick mats of vines covered the ground surface and climbed any adjacent object including old stumps and trees.  This becomes a problem for the native vegetation because the mat of ivy prevents significant amounts of light from reaching the forest floor and the climbing ivy roots can potentially damage mature trees.

GRI is proud to take an active role in the local environment by restoring the native plant community to its previous state before the introduction of non-native invasive plants.  For more information on how to volunteer for the next clean-up day, visit: http://www.solveoregon.org/

OEMA Innovation Award for Seismic Risk Assessment

The principals of GRI have provided the Port of Portland (Port) with geotechnical, environmental, and seismic-related consulting services for over 30 years.  The geotechnical services have primarily involved floodplain and waterfront developments along the Columbia and Willamette Rivers.  Notable projects include concourses, parking structures, and roadway expansion projects at Portland International Airport; multiple water-transportation terminals, wharves, bulkheads, and docks; various industrial developments and office parks (structures, foundations, piers and piling, parking lots, roadways, embankments, infrastructure design); and numerous projects involving rivers, including bank stabilization and dredging projects.

In 2015 the Port was awarded the Oregon Emergency Management Association (OEMA) Partner Award for Innovation for the recently completed port-wide seismic risk assessment.  In response to the 2013 Oregon Resiliency Plan created by the Oregon Seismic Safety Policy Advisory Commission, the Port’s management team selected their top 20 marine and aviation assets for evaluation based primarily on a combination of revenue stream and their potential role in supporting resiliency following a significant regional earthquake.  The objective of the project was to understand the general seismic vulnerability of selected critical Port facilities and to provide benefit/cost analyses of selected mitigation strategies that could be considered for inclusion in the Port’s Capital Improvement Program (CIP).

It was an honor to be a part of this innovative project and helping to increase the seismic resiliency of the Port and the Pacific Northwest. For more information about OEMA visit their website: http://www.oregonemergency.com/.

Advantages the DMT Can Bring to Your Next Project

The Flat Plate Dilatometer test (DMT) can be used to investigate soil properties and has many applications in geotechnical engineering.  Dilatometer testing has several benefits compared to other standard-of-practice in situ methods, such as the Standard Penetration Test (SPT) and Cone Penetration Test (CPT). Benefits of the DMT include the direct measurement of the small strain elastic modulus of the soil.  Additional geotechnical engineering parameters can be evaluated with the dilatometer data including lateral stress, shear strength and overconsolidation ratio.  The Dilatometer testing method is considered to be less intrusive to the soil than the SPT and CPT, allowing GRI to more accurately characterize the in situ soil strength and stiffness.

Because the test directly measures the elastic modulus of the soil, estimated foundation settlements are less conservative than traditional analysis methods.  The settlement evaluation can be completed using a linear elastic modulus based settlement evaluation with the foundation load and footprint.  Case studies have shown settlements estimated using the DMT elastic modulus are in good agreement with field measurements, generally out-performing estimates from SPT, CPT, or consolidation tests(Monaco et al., 2007).  DMT results also allow us to quickly estimate shear strength profiles, soil types, preconsolidation stress, overconsolidation ratio, and effective stress friction angle.

Engineering Applications of DMT Data

DMT4-reduced – Settlement Analysis of Shallow Foundations
– Liquefaction Analysis
– Slope Stability Analysis
– Deep Foundation Design
– Soil Characterization

The DMT was acquired by GRI in 2013 when Wes Spang joined GRI as a Principal.  Wes has over 30 years of experience and has been using the DMT for geotechnical design for the past 20 years.  Our other in-house DMT specialist is Jason Bock, a project engineer who has 10 years of experience and about 5 years of experience using the DMT for soil characterization and foundation design.
