The next two phases of the garage sidewalk project have been completed. The first of these was relatively easy, just a flat section in an alcove between the house and garage. A channel drain was added at the roof drip line and conduit added for future utilities to access the area (hopefully fiber eventually). The second phase was not as simple since there were heat pump units in the way. To get around this I installed a ledger board to the wall framing then made a frame out of old landscape timbers, with the frame legs outside the concrete area. The units were then carefully lifted onto the frames with ratchet straps, making sure not to stress any of the electrical/refrigerant connections. Concrete was then poured the same as before.
Next phase is one more small section from the heat pumps to the end of the wall, this will catch the rest of the rain run-off and direct all of it into a pipe that will run under the grass.
