About Us

Port Experience: CP&A has been involved in the port industry since our founding in 1987. We've brought together a dedicated team of structural, civil, and mechanical engineers, each possessing a wealth of experience in crafting cutting-edge engineering solutions. Recognizing the unique challenges posed by constructing projects within active marine terminals, our experts leverage their expertise in structural engineering, civil engineering, and mechanical engineering to develop designs that not only meet the highest standards but also carefully account for the continuous operation of the terminal during construction. Our holistic approach ensures that every facet of your project aligns seamlessly with the intricate demands of marine infrastructure.


Crane Experience: CP&A is an international engineering firm that specializes in container cranes, ship loaders/unloaders, gantry cranes, floating cranes, and other material handling equipment. The firm has been providing all phases of crane engineering for over 35 years. CP&A holds multiple patents related to container cranes, including the most recent ship to shore (STS) crane base anti-seismic isolation system (BASIS).


Aerospace Experience: Our first project was the structural engineering and mechanical design of a rail‑mounted self‑propelled 100 foot cube building at Boeing's radar range to hide experimental stealth airplane concepts from view of satellites. Since then, Boeing has been a repeat client for dozens of projects for special structures such as an aluminum platform subjected to deafening white noise, several overhead crane projects, and earthquake upgrades at the Everett assembly building reported to be the World's largest building by volume.

To our Chinese clients, CP&A has several exclusive advantages over other engineering companies.  CP&A has engineers fluent in Chinese and registered in both USA and China.  These advantages will minimize engineering miscommunications, and will assure that our Chinese clients get the best engineering services from CP&A.

Learn About Our History

CP&A was founded in 1987 by Bill Casper and Rich Phillips after relocating from California.

We started with pre-established worldwide recognition as structural engineers specializing in container cranes. To provide our ongoing clients with full multi-discipline crane engineering services we expanded our staff and associates to include mechanical engineers who specialize in cranes.

For the container crane industry, we offer a multi-discipline combination of mechanical, structural, electrical, and computer science engineering. The majority of our engineers have advanced degrees.

We have also expanded our crane expertise to now include most types of cranes from RTG, RMG, and Goliath cranes to B.O.P handlers on drill ships. Ports and crane manufacturers around the world use our crane engineering services to design and procure all types of cranes and load handling equipment.


For other industries we offer high quality structural and mechanical engineering services for projects that range from mundane, such as a conventional retaining wall, to specialized and complex, such as an aluminum framework designed to withstand -millions of fatigue cycles from rocket motor tests.

We are located in Tacoma, Washington within convenient driving distance from the Ports of Vancouver British Columbia, Seattle, Tacoma, and Portland.

Our Mission

CP&A is dedicated to providing the best in both client service and engineering excellence. Your expectations for service are uniquely yours. We are always open to your concerns and expectations as circumstances evolve. We urge each client to tell us what is important to them. Most projects have more than one good way to accomplish a task. Your input in selecting which one is best for you is always welcome.
