Beginning in 1996 as a small, heavy civil construction firm, our successes have been greatly dependent on our founding principles of Safety, Quality, Integrity and Flexibility. Every effort is made on every job we undertake to build a project utilizing those four principles. For that reason, DBA has been able to establish itself as a reliable, safe and quality contractor. This is evident in our consistent ability to obtain repeat work from our clients.

Delivery Methods

Alternative delivery methods are a form of advanced thinking and customer service.

Design-build, construction manager at risk, and job order contracting are all a part of DBA's history in Arizona. The benefits to our clients using these delivery methods include a true partnering spirit with the lead designers and other stakeholders, the ability to better control project costs and schedule, and to assist the team with innovative solutions to project challenges during preconstruction and in the field.

Construction Manager at Risk (CMAR) is a delivery method that entails a commitment by the CMR for construction performance to deliver the project within a defined schedule and price, either fixed or a Guaranteed Maximum Price (GMP). The CMR acts as consultant to the owner in the development and design phases, but as the legal equivalent of a general contractor during the construction phase.

Design-Build (D/B) is a project delivery method which combines architectural and engineering design services with construction performance under one contract. Variations include:

A designer is retained by the owner to develop the design documents to a specific point (usually schematic level) prior to engaging the Design-Build contractor, who then finishes the design and constructs the project.

A private entity or consortium of investors provides some or all of the required capital with a commitment to deliver a completed project for a public sector owner in exchange for revenue that the completed facility is anticipated to generate.

Hard Bid is similar to the Traditional Design-Bid-Build method. The owner hires an architect to design a facility in response to the owner's program requirements. The architect then prepares drawings and specifications to define the scope of work. Once the drawings/specs are prepared, a general contractor is selected typically on the basis of the lowest bid. The advantage of this method is familiarity, as this is the traditional, well known delivery method.

A long term, indefinite delivery-indefinite quantity contract for construction services delivered on an on-call basis through firm fixed price delivery orders based on pre-established unit prices.

Company History

Established in 1996, DBA Construction, Inc. operated as a small, highly specialized, concrete subcontractor. Devoting most of its time to specialty subcontracting in the Phoenix area, DBA grew its staff and resume to include all forms of heavy civil cons

Today, DBA employs over 125 construction professionals. The company owns a large fleet of heavy equipment including dozers, excavators, scrapers, backhoes, water trucks, dump trucks, and other associated equipment, minimizing the need for equipment rentals and allowing the company to self-perform over 85% of the work awarded. Work has continued throughout Arizona, but has also expanded to include several large projects in Texas.
