Experienced Mechanical Engineers That Understand Your Building Goals

NDBS grew out of St. Louis’ very competitive Design/Build market, where Design/Build is the predominant method of construction.  Our experience in this competitive marketplace has been a spring board to expand to emerging Design/Build markets across the U.S.  Over the past decade, we have built a track record of successful HVAC Design/Build projects in over thirty-five states.  Our commitment to quality and excellence is reflected in each and every one of our designs.  NDBS’ approach to the Design/Build process has resulted in the company being named one of the top 10 largest mechanical contractors in St Louis.


NDBS is a Leader in Green Engineering

In addition to cost savings, NDBS takes pride in protecting the environment for future generations.  We treat each and every community that we work in with the same high-level of respect that we treat our own.  We engineer designs incorporating initial cost considerations and life-cycle sustainability.  All systems that we install receive a complete commissioning to confirm that operation is within design parameters.
