case the pipe did freeze or become blocked. It wasn’t good to put back pressure on a spring.
The final project for the summer, into fall, was installing the heat sink piping for a geothermal, ground source, heating, ventilation, air conditioning (HVAC) system. It so happened that bigger was better, so Brady used 30” inside diameter clay tiles for the system. He marked out where he wanted the tiles to go. A second contractor put in more of the tiles. Both were told they were being put in now, but the system wouldn’t be completed until he was ready to build. He wanted to be able to landscape the area and not disturb it later, except for digging up the ends and making connections.
Since the contractors dug where Brady marked, they had no idea one of the strings of tiles stopped just short of the second “water tank”, with others conveniently placed where they would be adjacent to the buildings Brady would have erected. Some of them were actually for the HVAC system.
Brady put up a few more cameras with recorders around the perimeter of the main area. He drove down at least once a month during the winter to check the DVDs and change the batteries for freshly charged ones. All that ever showed up on the recordings was wild life, a great deal of it, and the occasional hunter passing through. None had done anything to the well, pumps, or pond, which were about the only things showing above ground.
The next spring Brady had the first structure on the property built. It was a large utility room and garage, built over a half basement with the well a ways inside one end wall. The foundations were substantial, including the basement walls. The building walls consisted of an outer wall of reinforced, grout-filled, concrete block.
Inside the block wall solid foam insulation was sprayed on, and then a twelve-inch-thick, staggered six-inch stud, wood wall was erected, covered on the living space with ¾” marine plywood and vapor barrier, and the space between the plywood and insulated block wall filled with minus ¾” crushed rock. A six-inch concrete ceiling was poured and then an enameled steel hipped roof installed over it, a thick layer of insulation being sprayed in to cover the ceiling.
The openings for several small windows, three regular doors, and three 9’ garage doors were left empty. The doors and windows would be installed later. Two cameras went into the building. There still wasn’t much to steal, just the pumps. The building might be vandalized, but Brady was prepared for that. Even the steps down to the basement area of the building were of steel, not subject to much damage.
The same with the electrical and plumbing. The rough-ins were done, but the finish components were not installed.
And then Brady had some walls constructed. Sort of here and there, going all different directions. Tall, thick walls with deep foundations. Some of them quite long. The walls were reinforced concrete block on one side and the ends, and interlocking retaining wall blocks on the other. The two rows of blocks were tied together regularly with metal ties. The area between the block walls was filled with compacted crushed rock. Five feet wide at the top, seven at the bottom. Two of the walls connected to the garage/utility building, but were freestanding on the other ends.
The walls took everything he had budgeted for the year, and then some. He got a couple of complaints from the gravel pit operators from which he was sourcing the rock. He was taking everything they were producing and his other regular customers were complaining.
But the business was booming. He and Harry, plus two others, concentrated on the detective work. Barbara was running the security operation and had hired two office staff to help her.
The following year Brady didn’t do any building. Instead he made occasional trips to camp out, change batteries on the surveillance equipment, and check on the place. And empty the heavily laden Suburban of its
