Thank you and your firm for the excellent engineering services that you provided on the recent levee certification studies for diking districts in southwest Washington. The topographic maps you developed for the levee systems at Castle Rock and the Port of Camas/Washougal were a key part in the FEMA levee certification process. You are to be commended for your helpful attitude and timely input during all phases of the project. Again, it has been a pleasure working with you and we look forward to future teaming opportunities.

In my positions at Cowlitz County Dept. of Public Works and Beacon Hill Water and Sewer District, I have worked with Gibbs & Olson on quite a few projects over the last 11 years ranging in variety from water and sewer line replacements and sewer and stormwater pump stations to land surveying. Gibbs & Olson’s expertise and integrity set them apart from other firms. Their team members provide excellent services and bring solutions that are in our best interest. It is without hesitation that I recommend Gibbs & Olson to others that need engineering and surveying services.

Astoria selected Gibbs & Olson to provide engineering services for our combined sewer separation project. The project limits include several known inactive and active landslide areas. Gibbs & Olson and Shannon & Wilson have not only provided sound design solutions to address our pipeline and roadway stability concerns, but have also provided regular and consistent communication throughout our project.

We have worked with Gibbs & Olson since 1995. When our wastewater treatment plant was under an Administrative Order, Gibbs & Olson worked closely with us to carefully evaluate all the feasible alternatives. They took into account how the costs for a new wastewater treatment plant would impact our community and our citizens. The final solution was cost-effective and the resulting plant is affordable to maintain. We appreciate their efforts and approach to solutions that work for us and continue to use Gibbs & Olson for our projects.

It is a pleasure to work with Gibbs & Olson. Together we have completed several projects including our new wastewater treatment plant and collection system, several street renovations and water system projects. Gibbs & Olson is readily available to answer questions. If my main contact isn’t available there is always another knowledgeable engineer available to assist in resolving a challenge. Their planning experience, design work and construction oversight is top quality.

During construction of the horizontal directional drilling of the HDPE forcemain under the Chehalis River, Gibbs & Olson and their subconsultant put the Contractor on notice that their drilling machine was marginal and could lead to significant delays. Gibbs & Olson’s proactive approach and knowledge eliminated a potential claim on the project after the drilling contractor got the drilling head stuck under the River and spent an extra week performing the work. Gibbs & Olson has always worked to protect the City’s best interest and I appreciate their proactive approach.

The Port of Chehalis has worked with Gibbs & Olson since the early 90s that has resulted in many projects being completed on time and on budget. The versatility and broad knowledge of their staff has been of great value to the Port. Of note is the Port’s landmark 66 acre wetland mitigation site which was skillfully designed and construction supervised by Gibbs & Olson with no net loss or gain of soils. The site was sculpted into a functioning wetland mitigation site which received praise from the Washington Department of Ecology. Additionally, the firm has completed several hydrology research and analysis projects for the Port and the local flood control district which have been invaluable to mitigate for and reduce future flood damage.
