Let's Talk

The HVJ Difference

HVJ delivers superior engineering services. We delight clients, employees, providers, and franchisees by always developing improved ability to succeed working together. Following is a sampling of comments we’ve received:

  • It is hard to compare HVJ to other subs, they just "get it" they know what you need
  • HVJ is very reliable; they are professional in the services they provide
  • They've been cooperative in working with the system to get our projects moved forward.
  • Their understanding of the technical side is valuable.  I'm not a geotech engineer and I need them to really know their stuff—they do.
  • Their services are excellent. They're not just responsive. They are reachable and available. They find a way to get someone out to the job and help out if needed.
  • HVJ does a really good job of producing a service that in return reduces our risk back to our client, which is the ecstasy of the team.

Much of HVJ's work is repeat business with long-term clients. Our accomplishments are a direct result of the individual effort and dedication of each HVJ employee and their commitment to the high standards and ideals set by HVJ's Management Team. The keystone of our business is the relationship we establish with each client that translates to a commitment to meet each client's unique needs on their project. Our entire team is trained to listen, take ownership, keep commitments, and stay in touch. Our difference is the unrelenting focus on the improving the ability to interact effectively, which is what makes a difference.


Company Profile

Herbert V. Johnson, PE, established the firm in 1985. We have become one of the largest specialty, minority-owned engineering companies in Texas. We have broadened our service lines by consistently listening to our clients' needs and in response, building our technical capabilities and expertise, providing intelligent analysis of projects and always providing value-added service.

To meet our firm's goals of providing superior services for our clients as well as creating opportunities for broadened firm ownership, HVJ Associates, Inc. has created a franchise business structure. We have taken this initiative as it allows us to expand our reach while preserving the firm's characteristics that our clients value. The business structure provides for local ownership, closer to the clients and communities that the business serves. The franchise component provides a cohesive system following our proven, successful business model and practices. Our franchise offices are created from our former offices, with the personnel, project experience, and equipment from those offices. The franchisee companies have been formed by trusted former employees of the firm.
