A Busy Week...Footing Forms and Footings Poured!
Although I was a little unsure about the levelling process now that I have seen it, its much simpler than what I was expecting. The footing contractor lays out the forms according to the survey pins. he then uses a transit to find the highest/lowest point. The go to the corners and sights an elevation and pound a nail into the inside of the form. then they go to another corner, or along the form, sighting elevations to match the previous. Then they snap a chalk line between the nails on the inside of the forms and that gives them a measure of how much concrete to pour. This work took about a day. The concrete gets poured in less than 20 mins. As the concrete was poured one of the labourors follows behind levelling the footing to the lines with a shovel by moving the concrete around. Another guy followed, further flattening the concrete with the end of rake. What you are left with is a poured footing, ready to set up over night to a nice set of hard concrete footings....A solid foundation for the Flatrock Passive House.
