What We Built

The new Dalchau Service Center includes Class A office space and multiple conference rooms with integrated A/V systems. Energy-efficient elements include an insulated tiltwall envelope, LED parking lot lighting, and a high-efficiency HVAC system with magnetic drive chillers. Rainwater collection and HVAC condensate recycling were incorporated for use in landscape irrigation.

How We Built It

Energy and water consumption were a key focus for the project. Tiltwall concrete sandwich panels with integrated insulation provided efficient structural and insulating properties at a competitive price. High-performance glazing, overhangs, and louvered sunshades combine to block excess glare and heat from entering the building. To reduce the heat island effect around the building, 100% of impervious surfaces have been constructed with high-albedo materials.

A computer model estimated the building would save 20% in energy cost over the industry baseline, and the owner has noted the results. Looking at data from the first eight months, energy use was 40% less than their other comparable offices.

Project Awards

ABC Central Texas Excellence in Construction Eagle Award

For the outstanding work on this project, American Constructors received the ABC Central Texas Excellence in Construction (EIC) Eagle Award. The EIC strives to honor those who exemplify the highest quality of workmanship in their projects, while upholding a dedication to building projects on time and on budget.

Tilt-Up Concrete Association Excellence in Achievement Award

The Tilt-Up Achievement Awards were established to honor projects that use site-cast tilt-up concrete to introduce new building types, advance industry technology and provide unique solutions to building programs. For more than 25 years, the winning entries have illustrated the variety, beauty, and flexibility of the tilt-up construction concept.

LEED Silver Certification

LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world. Available for virtually all building types, LEED provides a framework for healthy, highly efficient, and cost-saving green buildings.


“I’ve worked with many general contractors on large commercial projects in the course of my career and I can state without a doubt that the ACI team is one of the best. I appreciated their hard work and dedication. They don’t have a weak link anywhere in their organization.”
