Who we are
We are a well-established and growing employee-owned general contractor that operates throughout the United States. We have a strong track record of performance in bridge and heavy highway construction with a portfolio of work that includes highly visible and complex projects for Class 1, 2, 3 and commuter rail owners, state and local government agencies, and the Army Corps of Engineers, among many others.
We operate in a sweet spot in the construction industry—the capabilities and equipment of a large contractor combined with the expertise and attention to detail of a niche builder. Our agility and company culture reflect our humble, family-owned beginnings, while our reach and self-perform capabilities give us the ability to tackle large-scale construction projects.
We have built a strong reputation as problem solvers. This is a product of empowering our workforce not just to make detailed plans, but also to make the situation adjustments required by the nature of the complicated and complex jobs we take on.
Our approach creates a solid partnership between contractor and owner that ensures high-quality work, completed on time and within budget.

Our deep self-perform capabilities are a major contributor to our ability to produce the highest quality work at a highly competitive price. We have the ability to complete a majority of a project’s tasks with our own skilled labor union workforce, generally self-performing structural and site demolition, excavation, and concrete framing and placement. We self-perform other tasks such as structural steel erection and demolition, rebar installation, stud-welding, and other specialized ironworker functions.
Our pile-driving crews have the experience, talent and equipment to tackle a wide variety of h-pile, shell pile or wooden pile-driving jobs. Our millwrights and ironworkers routinely make complicated and sophisticated repairs to movable bridges and erect all types of equipment.

At ICC, we have developed a culture centered on promoting an injury-free environment and providing the safest workplace possible for our employees, clients, subcontractors and others who enter our construction sites. We believe that every accident, and therefore every injury, is preventable. This philosophy, as evidenced by our 0.65 EMR, is first on every ICC employee's mind and project priority list and constantly reinforced through ongoing training programs and field procedures.
We have developed a full complement of highly detailed, site-specific safety programs for a variety of project types and field conditions, including environmental monitoring plans for sensitive wet areas and lead containment plans for rehabbing older steel structures.
We are dedicated to elevating the standards for safety in the construction industry through a wide variety of methods, from our zero-tolerance substance abuse program to our fall protection program, which includes partnering with insurance industry leaders to develop the next generation of fall protection systems.
It is our goal and commitment to provide a place of employment where all employees are given the necessary time, training and equipment to perform their jobs without injury, and where supervisors view safety and health performance as a critical element of on-time, under-budget project completion.

Quality is a cultural and operational fundamental at ICC. We have had our Quality Project Program in place for decades, which includes continuously reviewing our processes to improve, based on four tangible drivers of quality and customer success:
A deep understanding of client needs Our clients often have complicated and time-sensitive services and operations that require seamless integration with the project plan and execution. Our construction team goes beyond contract documents to understand and support our clients' broader needs, schedules and operations.
A strong grasp of all design criteria We take the time to understand all elements of the contract, including drawings, specifications, geotechnical reports and schedule. When there are conflicts between the contract documents, specified systems or field conditions, we identify them early and work with the owner and design team to address them, maintaining the design intent with minimal impact on project cost and schedule.
Open, timely communications between all members of the team Open, efficient and ongoing communication among the project team is key to identifying, discussing and resolving project issues in a timely and cost-efficient manner.
Strict adherence to clear, exacting project quality standards The correct application of the standards outlined in contract documents results in a quality project delivered to our client. We achieve this through careful early material reviews, open pre-construction meetings, quality installation analysis and expertise sharing.
