About Us

Tue, July 29, 2014

As with so many construction firms, our beginning was quite humble: one truck and a tool box. Hard work, motivated employees, patient clients, passion and integrity have resulted in the company you see here.


Our Results

Our long history has resulted in the development of our highly skilled workforce that has extensive experience within a wide range of industries. Our broad knowledge base allows us to provide new and innovative ideas to client projects. We start by supporting the initial planning, budgeting, scheduling, and constructability of a project, and continue with the ability to support the on-going operating and maintenance.

Our Beginning

Corporate Values Safety, Integrity, Quality and RespectCorey Delta Constructors was founded in 1974 by Gene Waken. Mr. Waken, an alumni of several iconic mechanical/industrial firms, approached the management of the Dow Chemical Company plant in Pittsburg, California, with the concept of providing "open shop" services as a general contractor. A virtually unprecedented concept at that time.

With little more than a deep passion for and a commitment to excellence, we began the very treacherous journey to becoming a successful service provider and viable company. The list of clients that you see on Our Clients page is a testimony to our commitment to integrity in our every action, building trust and loyalty.

Our progress in the succeeding decades has been virtually linear in every aspect, fueled by the passion and perseverance of the extraordinary people that make up our company.
