• Construction of a 25-foot-long segment of retaining wall (SRW) section #D was in progress.
• Construction of RCC precast box culverts at the outlet area of the detention pond was completed.
• Ten (10) inch lifts were placed and compacted for the backfill of retaining wall (SRW) section #D using SD45B and trench packer BMP 8500 equipment.
• At the time of arrival our representative observed that work was in progress at the construction entrance with one (1) foot lifts being placed and compacted using CP54B and D51PX equipment.
• Density test results indicate that the compacted materials met the project requirement of 95% of the maximum dry density obtained by a Standard Proctor ASTM 698.
