Message from the CEO

Welcome. We hope you find the information you need, the projects which reflect our work, but most importantly the people who do the work!

BMB is a professional engineering and survey company. We offer civil and horizontal structural design and complete survey services. Our company has been in business in San Antonio for over fifty years. We have worked throughout Texas from the Pan Handle to Brownsville, Orange to El Paso, with a concentration on South and Central Texas.

In San Antonio, we have been a part of virtually every important addition to the City and County, including, HemisFair, the growth of the International Airport, National, County and City parks including the Historic Missions, The San Antonio Zoo, Hike and Bike parks like Salado Creek, drainage improvements to areas including the Olmos Basin, and the growth of UTSA, Alamo Colleges, and SAISD. We have highlighted people and projects which showcase our work over the past few years, but we have a very long list of work, of which we are most proud.

BMB is a small, woman-owned business and HUB Certified by the State of Texas. The existing ownership has been working together since 1982, and the current management structure has been in place since 1992.

Our stability and passion for what we do, has allowed us to grow, and stay up with the latest tools and methods, necessary for design in the 21st Century. The quote “Don't tell me how hard you work. Tell me how much you get done.”, exemplifies our work ethic. We want to answer the questions each client asks – what are you doing for me? Will your work be good, on time? Can you deliver this within budget?

We love our City and State, and feel like our work reflects not only our profession, but our intention of leaving something behind, which will “pay it forward”. Each of us volunteers with professional organizations which provide programs supporting education, preservation, conservation and the arts. We are family friendly and have a relaxed work environment, believing that a balanced life makes for better work. Our “Red Room tab will allow you to see us as the people we are, and the joy we have as a working family.

On behalf of all of us, thank you.
