Leigh & O’Kane LLC

Leigh & O’Kane L.L.C. is a Structural Engineering firm with a broad scope of services and experience. The firm works as a prime engineering consultant and consultant to the best architects and engineers in the area.

We have been in business in Kansas City since 1986 and have sustained growth by providing excellent structural design and responding to the needs of our clients. Our structural experience has grown to include buildings, bridges, and infrastructure. As a complement to the engineering, Leigh & O’Kane added construction services to our scope of work, including Special Inspections and Material Testing. This provides a further level of quality control for the project.

From wood structures to steel, masonry, and concrete, the firm has experience in all materials and all building types. A drive through Kansas City and beyond is a living portfolio of our projects in some surprising places.

Everything has changed since 1986: the design process, the codes, the structural analysis software, the drafting, the modeling, and the integration of both, the delivery method of documents and construction, and the speed of everything.

Everything has changed except the principles of good design:

• Safe structures

• Creative solutions

• Economical materials suited for the structure

• Thorough Construction Documents

• Good communication and service throughout the design and construction process
