About Us

Koga Engineering & Construction, Inc. is engaged in the segment of the industry commonly referred to as municipal & utilities construction. The industry as a whole consists of General Contractors, Subcontractors, Material Suppliers and Equipment Dealers. Koga Engineering, although licensed to do both engineering and building construction, concentrates primarily on engineering type projects involving excavation, utilities and roadwork.
"The Koga team is one of the most professional, responsible firms that I’ve had the privilege of working with in the more than 20 years that I’ve been in construction.  From the preconstruction and estimating services to their field personnel, they are responsive and attentive to the project’s needs.  Quality and safety are primary focuses.  Our project has a very tight budget and an even tighter schedule.  They have continually and repeatedly demonstrated commitment and dedication in their actions.  Koga has been a true partner in achieving the goals of the project.  I would not hesitate to use them again on another project and would wholeheartedly recommend them for your project."
