1. Excavation, marine mattress installation, and armor stone (Size B) installation operations were being conducted
today on the terminal groin between Stations 7+20 and 7+40. (See Photo #2 and #6).
2. Armor stone (Size A) was observed being delivered and offloaded from trucks during the site visit (See Photo #8).
3. The On -site Observer noted a large fragment of a stone along the outer portion of the groin's west side in proximity
to Station 5+00 (See Photo #5). Jim Gunn (CDC) was made aware.
4. Construction signs were observed in place and fencing was observed around the 4th Street and Shallotte Blvd
staging and laydown areas.
5. No work was observed at the Shallotte Blvd staging area. Signs and barricades were observed in place.
6. The On -site Observer noted a portion dislodged section of a marine mattress along the east side of the groin in
proximity to Station 5+00. The section of marine mattress was discarded (See Photo #7).
7. A scarp was observed immediately to the NE of the groin (See Photo #2).
Items Discussed with Contractor's Superintendent, Surveyor, Regulatory Agencies, ... etc.:
1. The property owner of 469 E. V Street told Brad Rosov (CPE) that cracks have been observed inside his home.
He attributed the cracks to the activity associated with the construction of the terminal groin. Brad Rosov
conveyed that information to Jim Gunn (CDC). Jim Gunn stated that the vibration sensors have not detected any
vibrations above 50% of the allowable threshold.
2. Richard Mattingly (CDC) told Brad Rosov that it was anticipated that 18 mattresses would be installed today
followed by the placement of armor stones (Size B).
Brad Rosov (CPE) told Jim Gunn (CDC) that several dislodged sections of the marine mattresses were observed
alongside the east portion of the groin. Jim Gunn explained that it is not unusual for a portion of the mattress to
break off during construction and it will not result in deficiencies in structural integrity.
