• Excavation of soil for the sewer pipe trench between MH A8 to MH C1 progressed.
• Two layers of 6072 cubic feet rock was placed and compacted in the temporary pond between Lots #19 and 20 using an Excavator (PC390LC), with each layer equal to 3036 cubic feet.
• One Layer of 1518 cubic feet of soil was placed and compacted at the top of the first layer of rock in the pond between Lots #19 and 20.
• Density tests results indicated that the compacted materials met the project requirements of 95 percent of the minimum dry density obtained by the (Standard Proctor ASTM 698).
