This afternoon, we spent the time going over the drawings, calculating the
exact positions of the sewage pipes coming out the ground (and through the
concrete slab). We also discovered that the swimming lane is pretty accurate
and parallel to the house. This and the garage as the 2nd reference point,
will form the basic alignment for the whole house.
We created a spreadsheet of all the distances from each of the batter boards markers to all “interest” points on each of the three sewage pipes we have got to
run under the house.
We now have these numbers, we can start marking and cutting the narrow
trench lines for the plastic pipes to go in.
