Detailed Observations:
1. CDC was observed arranging armor stone (Size B) to meet the project design template. The excavator was working
between Sta. 6+40 and Sta. 6+00 (See Photo 8).
2. A trench was observed on the western side of the structure between Sta. 5+80 and Sta. 6+90. CDC excavated the
trench to expose the armor stone along the toe of the structure (See Photo #3).
3. McLean's crew was observed constructing the form for the concrete cap along the landward 100 ft. of the installed
sheet pile wall (Sta. 0+00 to Sta. 1+00) (See Photos #3 and #4).
4. McLean's crew was observed working with CDC to remove the temporary ramp over the installed sheet pile near
Sta. 2+50 and made final adjustments to the final elevation of the seaward 100 ft. of installed sheet pile.
5. CDC was observed excavating sand from the stockpiled material and loading it into off -road trucks that
transported the sand to sections of sandbags the Town had identified to be covered with sand. CDC was observed
placing the sand on sections of sandbags at the end of Lumberton St. and Durham St. (See Photos #5 and #6).
6. Stone fragments were observed along the waterline near Sta. 2+50 on the east side of the structure.
7. No escarpments were observed along the accretion fillet shoreline between Sta. 1+00 and 10+00.
8. Several beach goers were observed fishing from the end of the terminal groin structure. The on -site observer
informed them of the safety risks and asked them to stay off the structure.

Items Discussed with Contractor's Superintendent, Surveyor, Regulatory Agencies, ... etc.:
1. Adam Priest (CPE) spoke with Mike (McLean) about the concrete cap form construction. Mike indicated that the
form for the first 100 ft. should be completed by Thursday (3/24) afternoon and that he anticipated pouring
concrete at 10 am Friday (3/25).
2. Adam Priest (CPE) spoke with Richard Mattingly (CDC) about the stone fragments observed near Sta. 2+50 on the
east side of the structure. Richard indicated that CDC has been picking them up periodically during lower tides
and that the crew would be continuing this process until all of the stone fragments are removed.
A Bi-weekly meeting was held at the OIB Town Hall to discuss the status of the terminal groin construction. The
meeting was attended by Daisy Ivey (OIB), Debbie Smith (OIB), Adam Priest (CPE), and Richard Mattingly (CDC)
and Jim Gunn (CDC), Richard Gunn (CDC) and Brad Rosov (CPE) attended via Zoom. Daisy inquired about the time
frame for completion of the rubblemound structure, Richard Mattingly responded that there was roughly 330 ft.
more to complete and he anticipated it would take several more weeks to complete. Adam asked if the Town
had received any volume quantities for the accretion fillet from the USACE. Daisy said they have not received
anything, but she would reach out and request the volume data. Daisy asked Jim Gunn if he would provide a cost
estimate to spread the remainder of the stockpiled material left over after the sandbags were covered and the
gap filled in up to the terminal groin. Jim indicated that he would provide an estimate tomorrow (3/23). Jim
asked about getting permission from the regulatory agencies to demob several pieces of equipment from the
east end sand spit. Brad said that he would reach out to the appropriate regulatory agencies and get back to
him. Brad asked if the Town had begun planning to install sand fence and plant vegetation at the covered sandbag
locations. Debbie mentioned that they were in talks with a contractor to plant the vegetation and install hay
bales.
Were any issues identified today which may result in a field adjustment report, contract modification,
request for interpretation, or noncompliance? If so, describe:
1. No issues were discussed today.
