- Seismic and numerical modeling were used to evaluate load performance of the 520 Floating Bridge over Lake Washington – one of GeoEngineers' most successful design-build projects.
- The new Cove Lane roundabout and I-210 overpass in Lake Charles, Louisiana.
- Construction on ground improvements at Port of Portland’s Terminal 6, where our team used a PBE approach to maximize limited resources.
- The overpass and new administration building at the US/Canada border crossing at Peace Arch Port of Entry in Blaine, Washington.
Fuel cleanups, right-of-way improvements, landslide evaluations—we have the staff and the experience to achieve appropriate and effective solutions.
GeoEngineers’ national construction design team specializes in a suite of interdisciplinary engineering design services for heavy civil contractors. Their work includes temporary structural design, geotechnical investigation and design, temporary excavation support, soil-structure interaction, seismic modeling and dewatering—all under one roof. This approach gives contractors a single point of contact and more predictable pricing for complex and fast-paced infrastructure projects across the United States and abroad.
GeoEngineers performs feasibility studies at the beginning of many of our projects to identify the most efficient methods and routes to connect point A with point B, and many points between. We look for critical areas, such as wetlands or endangered species habitats, geological hazards, such as areas with landslide and seismic risks, infrastructure to avoid, and work with clients and regulators to evaluate the feasibility of various approaches. By evaluating potential hazards and potential approaches to each project through due diligence studies, GeoEngineers strives to reduce our clients’ risks.
In today’s regulatory framework, most transportation projects demand integrated federal, state, and local permitting. GeoEngineers’ permitting professionals are here to help you create and implement realistic strategies that will help your project move forward in a timely and compliant manner.
We help your project stay compliant, and coordinate conversations between the public and the many stakeholders typically involved in large-scale transportation projects. Our permitting support includes critical areas ordinances, EIS, NPDES and state discharge, dangerous/hazardous waste, NEPA/SEPA, FERC compliance, Clean Air Act, Endangered Species Act, fisheries and hydraulic projects, water rights, and water quality permitting.
GeoEngineers uses a combination of methods to improve soil stability, including the design and installation of drains and various preloading strategies. We specialize in ground-improvement programs in soft soil and earthquake-prone areas. Our Performance-Based Engineering Team performs seismic analyses and numerical modeling to predict the interaction between soil and foundation structures during specific types of seismic events.
We provide stormwater control and quality testing, along with expertise in federal and local stormwater discharge regulations and investigation of subsurface water flow. We reduce and control stormwater runoff during project construction, and design permanent stormwater management strategies for transportation infrastructure, from port terminals to highway culverts.
We integrate transportation infrastructure with ecological expertise to protect sensitive fish populations in the Pacific Northwest and beyond. More than a decade of work in geomorphic process-based fish passage and habitat enhancement has taught us how to efficiently and sustainably help our clients meet their design requirements.
For some of our transportation projects, especially those built on soft soils, conventional force-based and factor of safety approaches may not be adequate. In these cases, GeoEngineers looks to our performance-based engineering (PBE) team. Using a performance-based approach to risk replaces absolute factor-of-safety standards with a more robust strategy for building resilient infrastructure. PBE evaluates the reliability of the design by considering a variety of real-world loads and conditions a structure is expected to face instead of just one design load and condition. This can also lead to increased efficiency and decreased cost. Funds which might have been needed to build a structure to a rigid, and sometimes unnecessary, factor-of-safety standard can be reallocated to address more meaningful risks. Visit our PBE Frontiers Page for more information on this growing service area.
Helping shield our clients from risks is at the core of our consulting practice. We assess risks that can cost our clients money, time and resources. By identifying these risks early and offering mitigation strategies, we give our transportation clients the tools to make smart, safe business decisions.
When everything is on the line, GeoEngineers will do whatever is necessary to restore transportation arteries following a release or other incident. Our combination of environmental remediation and transportation expertise is critical when time is a factor. GeoEngineers is ready to characterize any environmental impacts, mitigate the damage, and design a plan to safely reopen roads, bridges or waterways.
In today’s regulatory framework, most transportation projects demand integrated federal, state, and local permitting. GeoEngineers’ permitting professionals are here to help you create and implement realistic strategies that will help your project move forward in a sustainable and compliant way.
GeoEngineers provides far more than geotechnical and environmental recommendations and guidance. We’re there every step of the way during project construction, working closely with contractors to ensure that the earthwork elements are constructed according to design recommendations and that hazardous materials are removed and categorized appropriately for disposal.
We help clients manage and organize their data. We use our in-house data management software platform, Earth Analytics, to help us monitor and manage instrument data. From discrete, short-term monitoring to expansive networks of wireless instruments tied into our software platform, we have the range of services to meet your needs.
GeoEngineers staff have decades of experience testing driven pile foundations using the pile driving analyzer (PDA, a non-destructive method or NDT). We have PDA and Crosshole Sonic Logging (CSL) equipment in-house to meet large transportation project needs. GeoEngineers also has experience in providing specialized geotechnical field testing such as inclinometer slope monitoring, settlement monitoring, and soil pore pressure monitoring.
Our accredited labs and technicians are available for your special inspection and testing needs. We have laboratories accredited by the American Association of State Highway and Transportation Officials (AASHTO) and the ASTM Cement and Concrete Reference Laboratory (CCRL). We also maintain specific state-required certifications to conduct materials testing, including earthwork, reinforced concrete, structural masonry, structural steel, structural wood framing, proprietary anchors and fireproofing materials.
