Remembering, thanking, blessing, 9.11.01There's still some tweaking to be done with the excavation. Zac from MPW Construction arrived to check the progress. Measuring, marking, looking at the plans, measuring again, marking some more. Brian and Johnny will be back today to catch this bit of excavation. Then the forms for the footers will be added with cement being poured on Monday if all goes as planned. Framing to start soon after that. This is soooo exciting. Again the weather is AWESOME!
Trevor Miller, from Brady 3 will give us a construction schedule at the beginning of the week.
Bill Schwin from MPW Construction arrived with geodimeter in hand to pinpoint, and I mean pinpoint, the exact location of the corners to the footers. He was out earlier marking the front yard before excavation started and returned to remark the points. The footer forms will follow straight lines to and from each corner pin. This is the same kind of equipment siesmologists use to monitor movement of volcanoes.
How did he know where to start? For those who are so far out of the realm of visual trigonometry as I am, the points were drawn up and uploaded to the brains of the equipment standing on a fixed point outside the excavated area. The gizmo on his arm relates information between the brains (geodimeter) and the reflectometer he is moving around, to find the exact point for the pin. The g-meter has a level, as everything should to ensure perpendicularity, which is of course the straight and narrow way to walk!This ensures the squareness of the new construction, while at the same time points out the out of squareness of the existing structure. Ahh, the advances of technology since 1925 when the original structure was built.
Really, really interesting. Dad read this and just shook his head - overwhelmed with the technology today (since he used to do some of this work without machines. It is called digging by hand).
ReplyDeleteI am not even going to address the seismology brain communication information - I just have a simple question:.
ReplyDeleteAre you going to put the addition around the right corner of the house? (right side as one is looking at the house from the front)
Susan
The new addition actually goes in front of the old garage and part of the porch, which will be reworked with a new entrance from the right side. All of the addition will stay in front and the left side.
