GRI Celebrates Earth Day at Tryon Creek State Park

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.

GRI and KPFF Win the 2015 COPRI Project Excellence Award for Port Of Newport International Terminal Renovation

COPRI Blog Photo2The Coasts, Oceans, Ports, and Rivers Institute (COPRI) announced in June that the 2015 Project Excellence Award in the Large Project Category was awarded to GRI and KPFF Consulting Engineers for the Port of Newport International Terminal Renovation.  GRI Principal, Scott Schlechter accepted the award at the ASCE ceremony held in Boston, Massachusetts earlier this month.  This project also received the ACEC-Oregon 2014 Grand Award for Engineering Excellence in the Transportation-Marine/Ports Category.

The Port of Newport International Terminal is located in Yaquina Bay on the Pacific Coast in Newport, Oregon, and serves the fishing and timber industries of the Northwest.  Due to major deterioration of the WWII concrete hull ships that were sunk to create the berths, significant portions of the Ports facility were shut down.  Goals for this project were to develop a design to renovate the facility that could be implemented in phases as funding was available and to create a terminal that would once again serve the large fishing and timber industry in the area.  It was also necessary to remediate ongoing contamination issues that developed as the most unstable ship continued to break apart and leak fuel-based contaminants into the bay.

Success of the project has allowed the Port of Newport to fulfill its mission to build and maintain waterfront facilities and promote/support projects and programs in cooperation with other community organizations and businesses that will retain and create new jobs and increase community economic development.

GRI has been involved with this project since 2000.  We worked closely with the owner, design team, and CM/GC contractor to select the design and construction alternative that best met the challenging geotechnical, structural, environmental, and financial constraints of the project.  The project was successfully completed in November 2013.

GRI is honored to have been a part of such a challenging but rewarding project, and we strive to continue to deliver the same degree of excellence to every project.
