Experts in the Principles and Practice of Post-Tensioned Concrete and Seismic Design

Specialists in post-tensioning and seismic design, not generalists in everything.

Seneca Structural Engineering, Inc. provides specialized post-tensioning and seismic design. That focus — rather than a broad, do-everything practice — is what lets the firm push into more efficient, more inventive solutions for both new construction and existing structures that need strengthening.

The majority of the software used by the firm was written by the principals and focuses on exactly the types of projects that the firm regularly engineers, creating even more efficient designs.

The firm is led by two principals who between them have designed, evaluated, and published on post-tensioned concrete and seismic design since the firm's inception in 1998: K. Dirk Bondy, S.E., and Bryan Allred, S.E. Their book and design software have been used by students and practicing engineers for learning and designs well beyond Seneca's own project list.

• 01 Post-tensioning is engineered on every project to meet not only the latest code requirements, but the current standards of care and practice
• 02 Principals perform calculations and create drawings directly; no hand-off to junior or drafting staff
• 03 Calculation packages are organized to help plan checkers and peer reviewers easily understand and follow the design intent, as opposed to overwhelming them with volumes of muddled computer output
• 04 Knowledge gained is passed on to other practicing engineers and the next generation through our book, publications, online webinars and University courses for the benefit of the entire industry
