Denver International Airport added their first new runway since opening the airport. This sixth runway, which is the longest public use runway in the USA, required that one of the fire stations be relocated to service the new runway without having to cross another potentially active runway during an emergency.
The new Aircraft Rescue and Fire Fighting (ARFF) Station 4 is modeled after the previous stations but responds uniquely to it's site. At the Owner's suggestion, the open courtyard near the entry was oriented toward the west to take advantage of the expansive mountain views and landing path for the new runway. This also allowed the vehicle bays to act as a sound buffer to the much closer runway just to the east. Earth berms, special acoustical windows and masonry walls were incorporated into the design to suppress the noise on the interior.
