This week, Steve taught us some tips and tricks on setting up batter boards. These batter boards will be used not only as a guide for excavating but also for setting the rebar reinforcement and pouring concrete. The strings that are pulled from stake to stake mark the edges of the footing and the middle string helps to delineate the center, where the screens will connect to the concrete. After the lines were taut and centered, the ground was spray-painted as a reference for digging, and the string was rolled back.
In a day the footing trenches were excavated! Most of it was dug with a mini excavator, but in areas where there were pipes, the digging was done by hand.
Considering the rain in the next couple of days, the team made a provisional cover with 2″x4″ and plywood that was sloped to let the rain shed off to the side. Then tarps were placed on top of the plywood so that the plywood didn’t get soaked.
