Hangar and Garage Foundation

Pouring the foundation for the hangar and garage is a separate step from constructing the foundation for the house.  Unlike the house, the foundation for the hangar and garage is poured in a trench without any forms.  That cannot be done until after back-filling around the basement walls.

This shows one corner of the basement walls before back-filling.  A hangar wall will join this corner on top of the blocks.  The basement walls have been treated and pea gravel has been added around the foundation. 

This is taken from what will eventually be the driveway after back-filling around the basement walls.

This is taken from in front of what will be the garage door as the garage and hangar foundation are being poured.
Due to the pass-through design of the garage and hangar, the side walls do not have the benefit of a full cross wall to resist racking.  Consequently, some additional measures are necessary to provide proper support.

A corner of the garage foundation. The rods and strap that are embedded in the concrete will firmly hold the walls to the foundation. 

Steel posts will reinforce the narrow walls on either side of the bi-fold hangar door.  These posts will be fastened to concrete pads by threaded rod.  The threaded rods are inserted into the concrete pads before the concrete cures.  A plywood template ensures that the rods are positioned correctly relative to one another as they are inserted.

This is one of the concrete pads on each end of the bi-fold hangar door.  The threaded rods are assembled into the template and waiting.

Inserting the threaded rods into the concrete pad.  The pink string marks a reference line from which to determine the correct position.

Carefully measuring to ensure that the rods are in the correct position.
