Caldwell wins Houston Agent's "Developer of the Year" Award

EHRA Engineering is excited to join in the celebration with Caldwell Companies in their achievement of receiving Houston Agent’s “Developer of the Year” award! EHRA believes in engineering with a purpose. The infrastructure and developments that we produce are key components in our effort to create impactful change in the communities that surround us. All of which, however, would cease to exist without our successful partnerships with the developers that make it all possible.

EHRA is honored to have worked with Caldwell Companies for more than 15 years in producing beautiful communities throughout the Greater Houston region. As a proud and long-standing engineering firm, it is our mission to execute the vision of our devoted developers. Our positive relationships with the leaders and staff of Caldwell Companies have led to award-winning residential development projects with the hope of many more to come. Fred Caldwell, Chief Executive Officer of Caldwell Companies, shared that, “It all comes down to trust. Is EHRA a partner we can trust? The answer is yes!” A partnership that was cultivated more than a decade ago has grown stronger than ever in our most recent and upcoming projects.

The best part about working with developers like Caldwell Companies is the opportunity to break the barriers of engineering. The 2,400-acre mutli-use lake community, Towne Lake, was awarded, "GHBA 2012 Master Planned Community of the Year" and is now considered a "destination for living and recreation." Chambers Creek, one of our most recent developments with Caldwell, is hoped to become the largest and most active 55+ community in Texas. It is our hope and achievement to bring new life and excitement to the communities we serve. Peter Barnhart, Caldwell Companies President and Chief Development Officer, stated that “The main amenity at Chambers Creek is going to be FUN!”

“Developer of the Year” is a tremendous achievement, and one well deserved. EHRA is honored to team with such talented individuals that share our passion for building a better future for Houston.
