Project description
What I am asking for is a proper grid of elevations and a cut-and-fill map. Please lay a square grid over the plot, ten by ten metres where the ground is calm and five by five where it breaks: at the gate, along the edge of the dip and near the old shed. Add extra points at the break lines and tie everything to a single datum. I would like the datum to be the threshold of the house, which is poured and cannot be changed, and I also want the kerb level at the gate shown on the same sheet, because the driveway has to drain to the street and not back towards the garage or onto the neighbour.
Then the design surface and the volumes. I need cubic metres of cut and cubic metres of fill separately, the balance over the plot, and the imported soil figure already increased for compaction, so that I order trucks by calculation instead of guessing. If there is surplus, tell me how many cubic metres and how many truckloads that is: there is room for a bank in the far corner. Separate design levels are needed for the paths, for the parking pad by the gate and for the terrace behind the house, with gradients in per cent.
Deliverables: a table of existing and design elevations point by point with working heights and signs, the cut-and-fill drawing with hatched zones and volumes written into each square, a volume summary, and a short note in plain words saying where the water goes after rain. Prepared for A3 printing plus the source table in a spreadsheet. I am not in a great hurry, but a week and a half would suit me, because the machinery is booked for the end of the month.
