Shelter Build Series 2
The ceiling form boards are attached to the trusses and the steel ventilation pipes are installed on the bottom form boards.
The riser blast hatch is attached to the riser truss pair. Note the matrix of rebar that runs through and parallel to the steel trusses.
This shelter was finished with a corrugated roofing material and a plastic vapor barrier on the walls. Note the sealant around the vent pipes and other penetrations. Also note the slope of the roof toward the hill. Water is directed to the drain pipes between the shelter and the hill shown on picture number two, above.
