Herbert V. Johnson didn’t found HVJ Associates just as a means to provide engineering services, but to create opportunity. Shortly after graduating college in 1985, Herbert founded HVJ with an initial focus on geotechnical engineering, environmental engineering, and construction materials testing. By the early 2000s, however, HVJ evolved to include pavement engineering and civil design services.

Herbert's idea for business growth, which are rooted in spiritual growth, is focused on improving the community and everyone who interacts with the firm.  As such, HVJ's structure was formed - paving the way for an engineering services firm with emphasis on character and learning.

The HVJ Difference

HVJ firmly believes that the success of infrastructure projects rests on the character of those involved. We delight clients, employees, providers, and franchisees by delivering on the ability to succeed working together each step of the way.

Through the years, we've compiled numerous comments from satisfied clients, including:

  • 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.

HVJ frequently works with previous clients to build repeat business and long-term relationships. 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.

HVJ works as an ambitious, supportive, and resilient team focused on each project's success.  To accomplish this, HVJ's ideals are implemented in each sector of our business, with special focus on inspiring excellence, owning the solution, growing with gratitude, and amplifying every voice.

The keystone of our business is the relationship we establish with each client, one which translates to a commitment to meet their unique needs for their projects.  The HVJ difference is the unrelenting focus on improving the ability to interact effectively with boundless enthusiasm and support.
