Yes Measurement: A minimum cover distance of 3 inches was measured between the steel reinforcing and the inside edge of the concrete form, the top elevation was checked to be within 0.02 ft. of the design elevation, and the reinforcement bars were measured to be 4 inches from the expansion joints. 18. Were any photographs taken? Yes 19. Was the drone flown today? Yes Detailed Observations: 1. Mclean was observed stripping the wooden forms from the underside of the shore anchorage section's concrete cap between Sta. 1+00 and 2+00 (See Photo #2). 2. Stone fragments and misc. debris observed within the excavated area in proximity to Sta. 0+00 to 2+00 of the sheet pile wall (See Photo #3). 3. Observations of the concrete cap formwork and steel reinforcement showed that a minimum of 3 inches of cover was being maintained between the steel and form work between Sta. 1+00 and 2+00. Plastic chairs were observed being used to support the steel rebar. Double strut coil ties were observed in place at every other sheet pile handling hole location (See Photo #4). 4. McLean's crew was observed pouring concrete between Sta. 2+00 and 3+00 (See Photos #5 and #6). 5. Materials Testing Technicians from ECS Limited and Carolina Ready Mix were observed on -site and testing the concrete slump and air content. The technicians also made 5 concrete cylinders (7-day, 14-day, and three 28-day cylinders) that will be used for compressive strength testing. 6. CDC and McLean lined a depression adjacent to the concrete cap with a plastic liner to be used as a washout location for the concrete trucks. 7. The top elevation was checked observed to be within 0.02 ft. of the top of cap design elevation. 8. Armor stones (Size B) were observed being delivered to the project site via flatbed tractor trailer from the Rockingham Vulcan quarry. All stones appeared to be within the size range for the Size B stone (See Photo #7). Cnn P■�ru,�n E■u■uun COASTAL PROTECTION ENGINEERING OF NORTH CAROLINA, INC.

The offroad truck was observed delivering the stones to the area adjacent to Sta. 3+00 where they were stockpiled (See Photo #8) 10. Several non -spec. stones were observed along the rubblemound structure primarily within Sta. 4+00 to Sta. 7+00. 11. The high tide the storm surge from the previous day brought ocean water to the base of the dunes and/or sandbags along the beach fill area between Sta. 1+00 and 30+00 (See Photos #9 and #10). 12.
