ASI General Contractors, Inc was founded in 1978 in Buena Vista, Colorado.  The company was owned and managed by two partners and operated as a regional heavy-civil contractor, with a work portfolio that varied from small dams, tunnels, and industrial construction with annual revenues typically at $10 million. 

In 1984 the company constructed Middle Fork Dam in Parachute, CO.  This was the second Roller Compacted Concrete (RCC) dam built in the United States.  Throughout the mid 1980’s the company established itself as a leader in RCC dam construction.

In 1987 the company was reorganized as ASI RCC, Inc. with ownership maintained by one of the original principals and several minority partners.   The company continued to operate as a heavy-civil contractor in the Rocky Mountain region and also maintained a leading position in the continually growing RCC dam construction market.  

In 1997 the majority ownership of ASI RCC, Inc. was purchased by Patel Engineering, Ltd. and at that time two long-time shareholders assumed management responsibility for all company operations. Between 1997 and 2000 annual revenues were increased from $20 million to $50 million as the company expanded operations to both the Southeast and Pacific Northwest 

ASI Constructors, Inc. was incorporated in December 2005 in Colorado.  In this corporate transition key management individuals purchased the majority of assets from the previous shareholders and re-established ASI Constructors as a domestic corporation. 

The company remains privately owned by managing principals and key employees with proven track records for successful project delivery through a professional and hands-on approach to business and field operations.

ASI is headquartered in Pueblo West, Colorado and operates throughout the United States. 


Annual water resource construction in the United States has fluctuated between $2.6 and $3.1 billion since 2000.  Continued strong population growth has created strong pressure to increase water storage and distribution system capacities throughout the nation.  

Dams and reservoir systems are the most economic means to store and distribute municipal and irrigation water, as well as providing for flood control, hydroelectric power generating capacity, and recreational use.  These multiple benefits have created a stable and steadily growing market for new dam construction. 

More than 79,000 dams have been built for water supply, power, irrigation, flood control, and recreation in the United States.  Many of these fail to meet modern engineering standards and most pre-1960’s-era facilities do not meet current regulatory safety criteria.

Existing dams have typically been designed for a service life of 50 years. Today, more than 30% of these structures have surpassed their original design life and require replacement or major rehabilitation, and before 2020 this figure will increase to 80% of dams in the nation.

Failures of aging dams can be catastrophic, with damage measured in lost lives, displaced communities, and multiple-millions of dollars.  Recent dam failures throughout the country have brought the condition of our nations dams into the media and political spotlights, and many states have embarked on major upgrade requirements for dams. 

Dam construction and rehabilitation is a technically challenging division of the water resources construction market.  ASI is a proven leader among contracting firms in this growing market segment with a 30 year history of successful project delivery.

ASI Constructor’s principals have been responsible for the profitable management and construction of revenues that consistently ranks within ENR’s top 5 in dams since 2001, exclusively in dam construction and rehabilitation.

ASI’s client base includes Federal government agencies such as the US Army Corps of Engineers, US Bureau of Reclamation, NRCS and Fish & Wildlife Service, various State and Municipal government agencies, regional and local water infrastructure districts, and private hydroelectric power generation utilities.

Public Safety Improvements

The first ASCE report card for our nation’s infrastructure was published in 1998 and dams were given a D letter grade. Subsequent report cards published in 2001, 2003, 2005 and 2009 have also given dams a D grade and, according to the Association of State Dam Safety Officials (ASDSO) the number of high hazard deficient dams has swelled from 488 in 2001 to over 4,400 now. As dams, and other water resources infrastructures continues to age these structures and systems will require ever greater maintenance and upkeep. As experts in water resources infrastructure ASI will continue to work to provide safe and reliable water systems. 

Regulatory Upgrades

With the heightened concerns surrounding terrorism and its potentially devastating effects on our society, the US Department of Homeland Security has established a dams sector in its counterterrorism division tasked with improving the security of our dams against a terrorist attack. With dams recognized in such a prominent role as a vital component and in need of vigorous protection, they are gaining much needed additional attention and associated funding. ASI has the expertise, equipment, and the capacity to participate in the upgrade and security of dams and water resources infrastructure.

Capacity Development

As populations continue to grow, and our water storage infrastructure continues to age, many water providers have begun to become concerned about securing future water supplies and increasing their water storage capacities. ASI has built, enlarged and rehabilitated over 100 dams in our 30+ year history and we will work on hundreds of these projects in the future. We have participated in every aspect of water storage projects, from feasibility studies and permitting through construction through operation and maintenance and we are proud to bring this expertise to our clients around the world.

Renewable Energy

Hydroelectric power is one of the most cost effective and sustainable means for energy production, a fact that is causing a large increase in hydropower projects around the world. Combined with a desire to become energy independent, the number of hydropower projects planned for the coming years is increasing dramatically. ASI has worked on and constructed dozens of hydropower and Federal Energy Regulatory Commission (FERC) regulated projects, and we are fully versed and familiar with all of the FERC regulations. Regardless of the type of project – pumped storage, existing facilities, expansions and enlargements, retrofits, ongoing operation and maintenance issues, etc. – ASI has the experience and expertise for the job.

Flood Control

Recent and dramatic flooding has underscored the critical importance of providing safe and reliable flood control systems for communities around the world. Many existing flood control systems are in poor condition and in need of upgrades, repair, and complete removal and replacement. As leaders in the water resources infrastructure market, ASI understands the critical role flood control system play and the complex requirements for their design, construction and maintenance. We are adept at working with a wide range of clients to solve these critical issues in timely and cost effectively ways.

At ASI we take pride in our work, and offer to you, only today’s most sophisticated engineering and construction technologies, along with innovative and cost-effective solutions to complex projects.
