GEOTECHNICAL DATA REPORT

1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of borings. The associated boring logs and laboratory data are presented in paragraphs 4.5 and 4.6, respectively. A character of materials paragraph is included to provide a comprehensive description of the materials utilizing both recent and historical knowledge of the project area. Also included in this section are definitions of terms and boring log notes, which provide additional explanation of the boring logs and drilling techniques.

Items discussed in the character of materials paragraph may not appear explicitly on the boring logs. Based on historic knowledge of the project area, the character of materials paragraph includes items that supplement the data documented by the boring logs. When reviewing the boring logs, use all of the data on the logs, including the materials description, legend, and blow counts. When evaluating the subsurface conditions, use all of the data, including the character of materials paragraph and boring logs.

During the solicitation period, any questions that pertain to the information provided in this section should be addressed to the contract specialist identified in Block 9 of SF1442. After contract award, questions should be addressed to the appointed ACO/COR, which will coordinate with Geotechnical Branch.

2 CHARACTER OF MATERIALS

The project includes the maintenance dredging of cuts SJ-60 and SJ-61 in St. Johns County, and cut F-2 in Flagler County.

2.1 THE LOCAL GEOLOGY

The project is located in the Atlantic Coastal Plain physiographic unit. The regional geology of St.

Johns County for the Quaternary and upper Tertiary Systems range from Recent to Pleistocene to Miocene age sediments. The Recent to Pleistocene age sediments are undifferentiated and cover the entire county and consist of fine to medium quartz sand and thin lenses of shell and clay.

These beds are generally discontinuous and vary within short distances both horizontally and vertically. The shell beds thicken and can become consolidated along the coast and form coquina of the late Pleistocene Anastasia Formation. These sediments occur at land surface and have an average thickness of 50 feet. These deposits lie conformably with the sediments of the Upper Miocene/Pliocene sediments. The Miocene/Pliocene sediments are comprised of interbedded layers of marine, fine to medium sand, shell and green, calcareous, silty clay and vary in thickness (20-75 feet) throughout the county.

2.2 MATERIALS ENCOUNTERED

The IWW in the vicinity of Matanzas Inlet has been dredged historically multiple times to -12 feet MLLW plus 2 feet overdepth. The materials to be excavated consist of shoaling that has occurred since the channel was last dredged in 2016.

The most recent vibracore borings were collected in 2008 and 2006, and represent the materials that typically shoal in the IWW Channel in the vicinity of Matanzas Inlet in St. Johns County, including the IWW cut F-2 in Flagler County.

Maintenance Dredging, IWW - Vicinity of Mantanzas Inlet

00 31 32 - 3

The encountered sediments within the dredging depth consist of poorly graded, mostly fine to medium grained quartz sand with trace to little sand-to-gravel sized shell fragments, and occasionally sand with silt. No rock was encountered.

3 DEFINITIONS

Definitions not explicitly indicated in the sections below are typical industry standard definitions from their respective ASTMs.

3.1 DEFINITIONS OF BASIC TERMS

4.3 BORING LOG NOTES

All Borings were sampled using an Alpine style, pneumatic vertical hammer, vibracore drilling apparatus having a continuous 20-foot by 3 or 3 1/2-inch core barrel with clear plastic core liner until refusal was encountered. Refusal is defined as no additional penetration of the vibracore with two minutes of additional effort applied to penetrate through the resistant layer at maximum vibration. The vibracore apparatus is equipped with a graph-type depth of penetration recorder.

5.5 BORING LOGS

Applicable boring logs are presented on the following pages.

The borings presented in this section are available historic borings within the project area. Most of the materials within the project template presented on the boring logs have been removed by previous dredging events with subsequent shoaling of similar materials. The current elevations of the materials at these locations are shown on the contract drawings.

While the Government’s borings are representative of subsurface conditions at their respective locations and vertical reaches, local variations in the characteristics of the subsurface materials of this region are to be expected. Accordingly, prospective offerors shall form their own conclusions from the examination of the recovered materials prior to submission of their offer.
