Step 3Foundation slabs
iImage Information

Forms were made to pour slabs that could be carried to the site. These slabs ensured that the bridge abutment was on solid ground, had adequate rise, and gave space for gravel fill. A specific bolt pattern was devised to connect the slabs using flat stock steel. The steel pieces were created after the slabs were dry and in place allowing for a little bit of variance.
Bolts were set in the forms along with rebar and all of it tied together with wire. Forms were tapped with a hammer and prodded well with spare rebar to ensure minimal air pockets.
