II. STATEMENT OF SERVICES

Description of Work.

The Contractor shall perform a total of 39 27 vibracores and 225 153 lab samples for this project. All coordinates are provided in Table 1. Following vibracore collection, the Contractor shall carefully transport the vibracores to a facility for processing. The collected vibracores shall be processed and field logs and photos provided to the COR.

Following the receipt of the vibracore logs and photos, SAW will require 5-business days to determine the lab test sampling interval for soils testing.

All vibracores shall be horizontally referenced to North American Datum (NAD) 1983 State Plane South Carolina Survey International Feet. The top and bottom of each vibracore shall be referenced to the MLLW vertical datum.

Sampling procedures for all vibracores shall be accomplished in accordance with paragraph “Vibracore Sampling.”

Field logs, Preliminary Drilling Logs, and Final Drilling Logs for all vibracores shall be accomplished with the paragraph “Drilling Logs.” In addition to the Field Logs, Preliminary Drilling Logs, and Final Drilling Logs, the Contractor shall take detailed photographs of each vibracore to highlight changes in lithology. Laboratory testing on USACE-designated samples shall be accomplished in accordance with the paragraph “Laboratory Testing Procedures.”

Performance Period.

The Contractor shall mobilize to the site to begin drilling within 5-calendar days following acceptance of the Accident Prevention Plan (APP). The entire work, including the vibracore drilling, logging, photographing, laboratory analyses, and the Final Report (hard copy and electronic files) should be submitted within 125 calendar days from time of award.

USACE Furnished Materials.

Map showing the vibracore locations are provided in Figure 1 while coordinates are provided in Table 1.

An Open Ground database, which includes the Open Ground core log template, shall be used to generate the drilling logs and will be furnished after contract award. GIS files of existing vibracores, NOAA charts, bathymetric data may be available on request.

Designated sampling intervals for laboratory testing shall be provided by the Wilmington District, based on the Contractor’s Field Logs and photos. The sample intervals for each field log will be provided to the contractor within 5-business days upon receipt of the field logs and photographic mosaic logs.

Vibracore Sampling.

The Contractor shall designate all vibracores as “EB-23-V-###”. Vibracores shall be performed within 20 feet (horizontally) of the locations provided by the Wilmington District (Table 1).

Vibracore drilling shall be accomplished by vibrating a sampling tube at either 10 feet, 15 feet, or 20 feet, with a minimum 3-inch diameter, to the maximum target depths below the ocean floor or to refusal (Table 1). Per the South Atlantic Regional Biological Opinion (SARBO) for the Endangered Species Act, the vibracore sampler will not be operated until the vibracore platform contacts the seafloor and vibracore barrel contacts the seafloor. The vibracore sampler will not be operated during retrieval operations (SARBO, 2020). The recovered sediments in each vibracore should not be less than 75% unless the collected vibracore encounters refusal. In order to document refusal, penetrometer data collection shall be recorded and presented to verify vibracore refusal. Vibracore refusal is defined as the sampling barrel having a penetration rate of less than 0.2 feet over a 30-second period. If vibracore refusal is encountered at the seabed, the Contractor shall offset up to 20 feet and conduct an additional vibracore attempt at a separate location within 20 horizontal feet of the original point. Location information and refusal depth shall be recorded for each location where refusal is encountered.

Given the dynamic nature of the project area, which includes factors such as shallow water, tidal influence, shifting shoals, and exposure to swell, if access to a vibracore location becomes impossible due to life safety concerns, immediate communication between the COR, KO, and the contractor's project manager is required to assess the need for location abandonment. Life safety concerns encompass issues or situations directly jeopardizing individuals' safety and well-being. If such concerns arise, the COR must be promptly informed via phone, with written communication sent to both the KO and COR detailing the encountered conditions during the location attempt. In the event that the Government concurs with the decision to abandon a location due to life safety concerns, the contractor will not receive payment for the vibracore collection at that location and logging and photographing since no vibracore was collected.

For each drilled vibracore location, real-time kinematic (RTK) Global Positioning System (GPS) surveying techniques shall be utilized to provide accuracies of 0.2 feet vertically and horizontally. The Contractor shall collect the actual coordinates (Easting and Northing) and top of hole (TOH MLLW) elevation of each vibracore at the time of drilling. Field Logs not containing proper coordinates and TOH will not be accepted. These are required in order for the Government to determine the number of lab sample picks per core.

Completed vibracores shall be carefully transported for processing, field logging, and visual soils classification. A photographic mosaic log depicting the stratigraphic horizons relative to depth shall be produced for each vibracore.

Vibracores shall be field classified and logged in accordance with ASTM D2488 “Standard Practice for Description and Identification of Soils (Visual-Manual Procedure).” The top and bottom of the vibracores and vibracore photos shall be referenced to MLLW vertical datum. Once field classification of the vibracore lithology is complete, the field logs, core photographs, and penetrometer records shall be submitted to the Wilmington District to select samples for laboratory testing.

Drilling Logs.

All drilling logs shall be developed using USACE Bentley OpenGround Cloud configured for the Edisto Beach project. USACE will provide necessary permissions to Contractors entering data. If the Contractor does not already have a license for OpenGround Cloud, the Contractor must obtain user-specific "named user" or concurrent licenses.

Field logs, at a minimum, shall include the date and time when each vibracore was taken, run time for the vibracore, the horizontal location of the vibracore (NAD 1983 State Plane SC FIPS 3200 International Feet), tide-corrected ocean bottom elevation (MLLW), and a visual description of the stratigraphy and the lithology in accordance with ASTM 2488-09A. Supplemental information including depths for the entire length of recovered material, vibracore recovery, and refusal depth shall also be denoted. The Wilmington District shall determine the sample intervals to be tested. Following Wilmington District’s sample selections, the Contractor shall designate the samples “S-1, S-2, S-3, etc…”, with top and bottom depths listed and send to the laboratory for testing. Once the lab data are compiled, Preliminary Drilling Logs shall then be developed with the necessary information mentioned above and include the laboratory data specified in laboratory testing procedure. Once the Preliminary Drilling Logs are reviewed and comments are addressed, they will be the Final Drilling Logs and can be submitted to the Final Report.

The Contractor shall conduct a QA/QC of the Final Drilling Logs to ensure that the coordinates and TOH elevations are correct, stratigraphic field classifications are consistent and within 1-USCS letter/symbol of the laboratory tested sample, and the graphical symbology utilized reflects the stratum described. The Contractor shall provide a legend or key to soil symbols and terms utilized.

Laboratory Testing Procedures.

Laboratory testing shall be the responsibility of the Contractor. Laboratory tests shall be conducted by a USACE validated soils testing lab. A listing of USACE validated laboratories is available at:

http://www.erdc.usace.army.mil/Media/Fact-Sheets/Fact-Sheet-Article-View/Article/476661/materials-testing-center/.

For estimating purposes, 39 27vibracores are to be collected. The maximum number of samples for which laboratory testing is required shall not exceed 225 153 samples. The exact number of samples per vibracore will be dependent of the materials encountered. Although up to 225 153 samples could be tested, the Contractor will only be paid for samples that are selected for laboratory testing by the Wilmington District. The Wilmington District shall determine the depth intervals for each test sample based on the Field Logs and photographs. The laboratory test reports shall include the project name, laboratory name, vibracore number, sample identification number, and date each sample was tested. The final laboratory test results shall be included in the Final Report and on the Preliminary and Final Drilling Logs.

Three (3) test procedures shall be performed on each sample:

1) ASTM D6913, “Particle‐Size Distribution (Gradation) of Soils Using Sieve Analysis,” modified by using the following sieve sizes: 1‐in., 3/8‐in., No. 4, No. 7, No. 10, No. 14, No. 18, No. 25, No. 35, No. 40, No.

60, No. 80, No. 120, No. 170, No. 200, and No. 230;

2) ASTM D2487 “Standard Practice for Classification of Soils for Engineering Purposes (Unified Soils Classification System);” and

3) Visual, volumetric percentage of shell and rock fragment determination. Visual percent shell content and visual percent rock fragment content shall be estimated for the 1-in., 3/8-in., and No. 4 sieve sizes.

Reporting Requirements.

A Draft Report shall be submitted to USACE for review and comment. The Draft Report shall include a description of the work, details of the underlying geology, final vibracore locations on maps and in a table, Preliminary Drilling Logs, penetration rate records and graphs, core photographic mosaics, and lab test data, complete with gradation tables and curves for each sample tested with a summary table.

The Contractor shall revise the Draft Report, incorporating Wilmington District’s comments. The Contractor shall submit the Final Report to the COR for USACE to review and backcheck that all comments have been appropriately addressed. Once accepted the revised report will become the Final Report.

Once accepted, the Contractor shall furnish one (1) hard copy of the Final Report, electronic/digital files containing the Final Report, all the lab test data in Excel and PDF formats, the USACE Bentley OpenGround database file, and ArcGIS shapefiles, layers, or feature classes showing vibracoring locations.
