Geometrix Northwest Surveying & Mapping
A Few Representative Projects
STRUCTURAL SURVEYING
Hwy 99W Pedestrian Crossing Project, Sherwood OR - 2024-2025
Awards: Pending
Client - Carter & Company
​
Geometrix Northwest is providing structural surveying for the assembly and transfer of this 5 span high-arched alternating structure with inverted arch trusses.
McKinley Grade Separation, Corona CA - 2024-2025
Awards: Pending
Client - Walsh
​
Geometrix Northwest provided structural surveying and unprecedented monitoring of this suspension bridge in Southern California. Geometrix installed surveying instrumentation mounted to the bridge and kept in collimation in real time through robotic servo-driven levelers. Ten prisms were monitored across the structure to check for twist and rack as OXBO transported the 2.4 million pound structure to its final location.
​
Earl Blumenheaur Bridge, Portland, OR - 2019-2022
ACEC Oregon, Engineering Excellence Awards, Project of the Year, 2023
ACEC Engineering Excellence Awards, National Recognition Award, 2023
Client - HP Civil
​
Geometrix Northwest provided structural surveying for this deck-tied steel arch bridge. Seen here Geometrix Northwest utilizes remote robotics to monitor and guide the bridge across I-84 with HP Civil and Omega Morgan.
​
Sellwood Bridge, Portland, OR 2014-2017
DJC Project of the Year 2017
Client - Slayden Sundt Joint Venture
​
Geometrix Northwest was recruited midstream to take over structural survey of the deck arch bridge and to provide quality assurance survey of the entire 350 million dollar project for the Slayden Sundt Joint Venture. In time, all survey work for the project was awarded to Geometrix. See our awards and testimonials pages for additional information.

OR 62 Corridor Solutions Unit 1, Medford, OR 2016-2018
Client - Knife River Materials Southern Oregon
​
Geometrix Northwest provided construction survey and machine control support for the 37 million dollar bridge and highway project in Medford, Oregon. The project included nearly two miles of white paving controlled by Trimble Robotics.
Elk Creek - Hardscrabble Creek Rapid Replace Bridges, Hwy OR38 OR
Client - Slayden Construction Group, A Stantec Company
​
Geometrix Northwest performed all survey work for this 50 Million Dollar rapid bridge replacement project, including 5 bridges, two of which were constructed outside the active alignment, and then rolled into place during a weekend closure.
​
Design Mapping
Gasco Shell Oil Site, Portland OR
Client - Anchor QEA Environmental
​
Geometrix provided multiple technologies to provide complete mapping from the air, terrestrially, and underwater. Photogrammetric mapping was used in combination with terrestrial robotics, LiDAR, and side-scan SONAR.
State Wide Airport Design Mapping
Clients - Precision Approach Engineering, Mead & Hunt, Coffman
​
Since 2005 Geometrix Northwest has provided design mapping to FAA standards for air-side improvements at multiple airports across Oregon. Geometrix is well versed in providing mapping to FAA Standards utilizing AC 150-5300 Sections 16, 17, and 18, including surveys of PACS and SACS.
Geodetic Surveying
Since 1992, Geometrix Northwest Principal, Randy Fitch, has performed complex geodetic surveys across the Pacific Northwest, from county wide geodetic surveys of PLSS corners, to DOT control surveys, to FAA Standard Primary Airport Control PACS Networks.
Deformation Monitoring Surveys
Sellwood Bridge, Portland OR
Client - Slayden Sundt Joint Venture & Multnomah County
​
Geometrix developed unprecedented deformation monitoring surveys of the multiple stages of steel erection and concrete placement. Throughout bridge construction reports were provided on key structural nodes to < .01' along with graphical exhibits tracking the structure's movements in real-time. Geometrix has provided monitoring surveys for tracking structures such as false work, bridges, walls, and buildings.
​
Vessel Tracking
Port of Portland Columbia River Dredging, Portland OR
Client - Dutra Dredging & Etrac Engineering
​
Geometrix provided real-time navigation for Dutra's Clam Shell Dredge when its GPS navigation system was off-line. Real-time data was communicated through telemetry from robotics to the ship's navigation system. Geometrix worked round the clock to allow Dutra's dredging operations to continue.
​
Geometrix also provides geodetic verification for dredging vessels such as the Stuyvesent (shown left) upon entering Oregon's ports as well as reporting for the Army Corp of Engineers.
