How do geologists use seismographic data to make maps of faults? Seismographs detect the reflected seismic waves and geologists use this data to map the length and depth of the fault. Why do geologists collect data on friction along the sides of faults? So they can try to predict the probability of a large earthquake.
The total cost for a concrete garage floor, including concrete, labor, supplies and equipment, varies region to region because of geographic variables. The total cost for a 400-square-foot garage floor in San Francisco ranges between $3.91 and $4.28 per square foot and between $3.26 and $3.60 per square foot in Atlanta.In suburban Chicago, the same floor will cost between $3.70 and $4.05 per square foot.he total cost for a 400-square-foot garage floor in San Francisco ranges between $3.91 and $4.28 per square foot and between $3.26 and $3.60 per square foot in Atlanta.

Just for the concrete on a plain driveway, the cost will average $6-$9 per square foot. Take some measurements of your driveway and create your own concrete driveway cost calculator. Be sure to include the garage floor if youâre having that replaced.For example, a driveway 14 feet wide and 50 feet long (14Ã50) contains 700 square feet.nowing these figures can help you calculate potential costs for contractors who charge a set fee for the number of yards of concrete required. For the 700 square foot driveway, you would need 8.6 yards of concrete for a 4 inch driveway and just about 13 yards of concrete for a 6 inch driveway.
