EBL, Inc. was founded in January of 1971 by Edgar Boyce "Ed" Laird. Ed Laird started EBL. with a small bankroll and a great deal of knowledge and a tremendous work ethic. EBL was a company known to do difficult projects which specialized in concrete structures, primarily bridges. Ed Laird possessed the knowledge to estimate and build the projects. He grew EBL into a company of 5 crews.

Ed Laird sold EBL, Inc. to his longtime partner H. L. "Harold" Gilbert. Under Harold Gilbert's leadership EBL continued to grow and do larger and more complex projects. EBL built many railroad and roadway grade separations, storm water pump stations and sound walls that were new to Houston during the 1980's.

Harold Gilbert sold EBL, Inc to W. K. Neely and David Boehm and at that time changed the name to NBG Constructors, Inc. To preserve the EBL legacy Mr. Gilbert kept the same Federal ID number and changed only the name of the company. NBG stands for Neely, Boehm and Gilbert. Kyle Neely joined the company and was responsible for the accounting, and insurance portion of the business. Thru the 90's and into the 2000's NBG, Inc. grew and earned a reputation of being able to coordinate and complete emergency repair projects. During this period Mike Westering joined NBG. Mike's immense knowledge of bridges, repair work and other structures proved to be an asset in obtaining and completing a greater volume of work. Harold Gilbert passed away in 2010 leaving Kyle Neely and David Boehm as sole owners.

W. K. Neely sold his shares of NBG to David Boehm. David Boehm is now the sole owner of NBG Constructors, Inc. During David's tenure NBG has grown in both employees and volume of work, and has built a team for small design-build projects. NBG continues to build new projects; overpasses, a cable stayed pedestrian bridge, decorative bridges, arched culverts and many other types of concrete structures. NBG has done many major bridge repairs including complete replacement of West Dallas Street over I 45, major deck repairs on Louisiana Street over Buffalo Bayou, and bank stabilzation of SH 99 at the Brazos River. It is our goal to continue the traditions and work ethic that Ed Laird and Harold Gilbert instilled in EBL/NBG. We thrive on difficult complicated projects by giving great attention to all the details from the owner to the laborers. NBG Constructors, Inc. has built a team of professionals in the construction industry that can compete with anyone.
