Former RAF Alconbury: Petrol, Oil and Lubricant (POL) Refueller Vehicle Shelter (Building Number 215)

The Petrol, Oil and Lubricant (POL) Vehicle Refueller Shelter at the former RAF Alconbury was built in 1988 for the United States Air Force. Designed by C Cavenagh and constructed by Fairclough Civil Engineering Limited, this structure is made of monolithic reinforced concrete.

The shelter has a rectangular double design, oriented from north-north-east to south-south-west. Its exterior resembles a double garage, featuring two pairs of blast-proof double-leaf steel doors beneath a continuous concrete drip course at the north end. A T-shaped roof ventilator is positioned above these doors. At the rear, there are two emergency escape hatchways, each topped with a T-shaped roof ventilator, while the return walls are blind.

Inside, the shelter is divided into two garages, each measuring 4.8 meters wide by 17.35 meters long. A reinforced concrete fire wall, 0.25 meters thick, separates the two garages, and there is a connecting door between them. The reinforced concrete floor has a maximum thickness of 0.80 meters and a minimum thickness of 0.65 meters at the main door end.
