Design / Build

Vancon pioneered the use of Design/Build Construction as a viable contract delivery method in the Dayton area. Since the inception of the company, Vancon has strived to find a better way to meet each client’s unique needs and provide each client with a superior value. With these goals in mind, Vancon developed a Two-Phase Design/Build Program that has proved to be an efficient way to accomplish this goal.

Vancon’s proven Two-Phase Design/Build Program, in combination with the additional services Vancon offers, and Vancon’s knowledge of the often overlooked factors that affect total project cost, set Vancon apart from other Design/Build contractors.

Two-Phase Design/Build Program


In Phase I Vancon will gather info, analyze the site, and investigate the building and zoning code implications before preparing a schematic design and conceptual estimate, along with a preliminary development and construction schedule.

At the completion of Phase 1 the owner will have the budget information necessary to make good business decisions without committing to the cost of a complete design or construction contract.

Site Analysis Pre-Design

  • Evaluate topography
  • Discuss proposed building footprint or review exiting drawings
  • Analyze building codes
  • Analyze zoning codes
  • Investigate soil conditions


  • Present information from the site analysis and discuss how it relates to the project and client needs
  • Confirm that the results of the analysis align with the client needs
  • Receive feedback and provide estimated cost
  • Prioritize and create owner’s program
  • Discuss ways to curtail costs up front and over the lifetime of the property.

Preliminary Development & Construction Schedule

  • At the completion of Phase I, Vancon meets with each client to present the schematic design, preliminary construction estimate, and preliminary development and construction schedule. Van Con also has the capability to help the client visualize the proportion and flow of the building through the use of a rendering or virtual walk-through of the building.


Upon the completion and acceptance of Phase I Vancon will prepare a construction contract agreement.
