As a service to our clients, H.E. Callahan provides a wide variety of delivery methods or approaches to construction tailored to the needs of the individual project.

Below is a breakdown of the services we provide:

General Construction

Working with owners and designers, H.E. Callahan provides traditional general contracting services by either competitive bid or negotiated contract. Working with our suppliers and subcontractors, the project managers and site supervisors coordinate the construction effort to ensure adherence to budgets and schedules. H.E. Callahan’s own field forces have the ability to perform concrete, steel erecting, and carpentry.



Increasingly, H.E. Callahan finds its clients prefer to have one entity responsible for all aspects of planning, design, and construction. H.E. Callahan provides this comprehensive service by uniting with HEC+A, a full service architectural firm that is innovative and responsive to our and the client’s needs. Together, we can bring a client’s vision to a built form for any project type, of any size.

H.E. Callahan can also furnish custom, pre-engineered metal buildings that are ideally suited to warehouse, commercial, or industrial uses due to our long lasting relationship with Varco-Pruden Buildings, a highly reputable metal building manufacturer that combines a steel structure with any exterior finish to create metal buildings that are energy efficient and provides years of trouble- free performance.


Construction Management

Construction management services are offered and ideally suited for certain complex, fast-track, or unusual projects. In this process, H. E. Callahan provides direction and leadership through the various phases of construction. We represent the interests of the owner by arranging for the design, bid phases of the work, administration of the contracts, and by ensuring timely and cost-effective construction. We feel strongly that as the general contractor we have valuable experience with this method and additionally can provide the resources and financial strength to guarantee the final price.


Construction Consulting Services

H.E. Callahan’s experienced staff of engineers, estimators, schedulers and project managers are available to assist owners and designers in the initial planning phase of a project. These services are often beneficial by ensuring accurate budget estimates, analysis of constructability, and developing realistic schedules. Often, value engineering studies at the early planning phase can result in substantial cost savings. The early collaboration efforts between owner, architect and contractor ensure a well planned and ultimately successful project.

H.E. Callahan believes that our primary responsibility is to ensure the Owner receives an optimum value for the budget available. This requires looking at all facets of the design, including product availability, constructability, first cost and life cycle costs.
