Earthquake engineering services

Our advanced design practices and collaborative approach foster success for our clients, partners, and the earthquake engineering practice.

Earthquakes are shifts in the earth’s crust that can result in small-scale damage to regional devastation. Whether you’re seeking geotechnical and seismic design for a building, bridge, or port, there is much to consider. You cannot risk the costs and schedule impacts that come with design modifications from permit reviewers, especially for performance-based seismic design (PBSD) of tall buildings – a smooth review process is essential. If you’ll own a site for the long-term, you may need a cost-effective design that exceeds code minimums and is focused on resiliency with reduced damage and repair/replacement costs following a major earthquake.

Regardless of the project, you need a trusted partner who stays ahead of the evolving seismic regulatory requirements, is at the cutting-edge of the practice, and will advocate for you at every step.

Haley & Aldrich’s earthquake engineering team has earned a reputation for excellence in advancing the practice for more than 20 years. We continually improve upon leading-edge earthquake engineering tools, technologies, and approaches for one purpose – to serve our clients’ best interest. As a result, our clients experience efficient peer review and permitting processes, and ultimately reduced seismic risk, construction time, and costs.

We were involved in the first PBSD project in Seattle over 20 years ago and have the most experience of any geotechnical firm in PBSD in the Northwest. We stay abreast of the changing ASCE 7 peer review standards and have been first to implement those concepts for our clients’ benefit – even before some are officially adopted. In one case, our early adoption allowed us to use more realistic ground motions that resulted in lower seismic forces and a less costly building.

Combining collaboration and experience for efficient peer review and permitting processes

Our clients often tell us that what sets us apart from other consultants is our ability to collaborate, listen, and provide thoughtful responses when teaming with others and specifically during the peer review process. This allows us to quickly come to resolution with peer reviewers and teaming partners, ultimately reducing negative impacts to the project schedule and cost.

Haley & Aldrich’s earthquake engineering team is highly respected in seismic regions throughout the U.S. Our clients, peers, teaming partners, and regulators often call on us to provide expert guidance even when we’re not directly involved in their project. During projects in which we are involved, we take the time to share our experience and expertise with our project partners. These trusted relationships foster success for the project, clients, and the overall earthquake engineering practice.

We provide earthquake engineering services for the following markets:

At Haley & Aldrich, we know you need a trusted partner who can deliver technical excellence, as well as understand and advocate for your best interests at every step of your project.
