About
Lach Engineering
We pride ourselves on the quality of our work and the value we bring to the industry.

Providing Excellent
Consulting Engineering
Since 2006, Lach Engineering has been providing engineering solutions to clients serving the commercial, industrial, DOT, lighting, and utility markets. Although our core area of expertise lies in structural design of lighting poles, traffic signal supports, overhead highway sign structures, and foundations, we are equally proficient in design of transmission poles, distribution poles, and substation structures.
Lach Engineering is a family-owned company. Each one of our staff members is handpicked to represent our company, which means serving as an extension of our family. This way of thinking and working culture is essential to our continued success. This mindset crosses over to our clients, most of which have been working with us since our inception. We have collaborated with many of our clients, coupling their engineering needs with our services, allowing us to effectively operate as their external engineering department.
