April 18: Building Concrete Forms

 Erik uses a transit to precisely pinpoint the pier elevations.

A rebar grid is placed in a footing, continuous under the

four East piers to resist potential seismic forces.

 The rebar grid must centered and tied to the forms prior to pouring concrete.

 The piers on the East side are square to accommodate the larger post bases.

High uplift capacity post bases are placed in pier forms.
Concrete will be poured around them.

 The forms pass county inspection.

  One of the piers required a pump to remove the ground water seeping in through fractured bedrock.  

John Cadden returned to the site to excavate for footings for all the barn posts. Erik and Scott then built plywood footing forms with rebar cages tied inside them.  Sonotube pier forms were then secured to the top of the form boxes.  Most of the posts are on individual piers, however the east wall of the barn required a continuous footing with four piers which resist seismic forces on the structure.
