Lockheed Martin and Hatzel & Buehler’s working relationship began in the early 1990’s with a building renovation to one of the Lockheed Martin facilities in South Eastern Pennsylvania. Hatzel & Buehler has maintained an ongoing relationship with Lockheed Martin at this location and other such locations, including data centers, administrative offices, research facilities, manufacturing facilities and development facilities.

Recently, Hatzel & Buehler performed a complete replacement and upgrade of the security system for all buildings within the South Eastern Pennsylvania campus along with other such upgrades, renovations & installations. Hatzel & Buehler is proud to be known as a Valued Lockheed Martin Supplier.
