These images are from Stanton
Airfield, Stanton Minnesota. Two
Ensign “Northern Edition” Sailplane hangars are being built here. To the right is a picture of one of the prepared sites. We first had an excavator remove 2 feet of topsoil with heavy equipment. We then had 24-inches of crushed aggregate placed in the “hole,” with the top of the fill compacted and leveled to become the new “grade-level” referred to on the blueprints supplied by Ensign’s Engineering firm. Though only 6 inches of fill is called out on the plans, we wanted to use plenty of dry, well-drained fill to minimize the effect of frost heave on the slab. The site was slightly over-sized to allow some improved drainage as well. |

The NORTHERN EDITION plans calls
for 18-inch wide and 48-inch deep footings for the three support posts. This then required the concrete to be reinforced
with a 12-inch wide, 40-inch deep rebar cage for each footing. We spent about $65 per building for the #3
(3/8th inch) and #4 (1/2-inch) rebar called out in the plans. The box contains rebar ties
(wire loops) needed for making the rebar cages. |

|
Pat Watson and Kent Johnson used
a torch to first cut the rebar to the sizes needed. The stock material came in 10-foot lengths. We cut the #3 material in thirds (40”) and
the #4 material in half. For one
building’s worth this took nine #3 and five #4 10-foot lengths respectively
for the three cages. |
|
|
We used chalk to mark the cuts
and within 30 minutes it was all cut.
Set-up and cutting took roughly 1-man hour per building. |
|
|
We then used the torch and a
1-foot pipe to make the 180-degree bends in the #4 material (heating up the
bend point), and used a hole in a tractor hitch to aid manually bending the
#3 material into a circle (no heat used).
This part took 2-man hours. |

cages took 4-man hours (only 3 cages were needed for each building). |
