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 5.6 and 5.7, 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

2.1 REGIONAL GEOLOGY

The east coast of Florida consists of a series of sandy barrier islands, broken by inlets. The coastline is relatively straight with the exception of Cape Canaveral. The source of the silica sand present on the Florida east coast is from the Savannah, Altamaha, and other rivers of Georgia and the Carolinas. The sand was carried down to the sea by the rivers and deposited. Coastal processes such as shore currents and wave action transported the sand gradually to the south.

The underlying material of the majority of Florida beaches contains a large portion of unconsolidated sand and shell mixture deposited during the later stages of emergence.

2.2 THE LOCAL GEOLOGY

Sediments of the Pleistocene and Holocene Age were deposited during the formation of marine terraces and beach ridges. These sediments blanket all of Duval County. They overlie the upper Miocene or Pliocene deposits and were deposited on a slightly irregular, undulating surface.

The thickness of the Pleistocene and Holocene deposits ranges from less than 10 feet in the St.

Johns River valley to about 100 feet in western Duval County. The deposits are thickest below ridges and in places where they overlie depressions in the surface of the upper Miocene or Pliocene deposits.

The Pleistocene and Holocene deposits consist primarily of tan to yellow, medium to fine-grained quartz sand, that are locally stained rusty brown or red due to iron oxide. The deposits locally contain thin grey sandy clay beds that, in places, contain mollusk shells, particularly near the coast. Discontinuous layers of rusty brown hardpan, composed of slightly well indurated iron

00 31 32 3 oxide cemented quartz underlie some of the higher areas. The hardpan is generally 2 to 3 feet below the surface and ranges in thickness from ½ to 20 feet.

2.3 MATERIALS ENCOUNTERED

The character of materials within the offshore borrow area is indicated on the core boring logs and laboratory data appended to the end of this section. The material within the borrow area consists primarily of poorly-graded, mostly fine to medium-grained sand-sized quartz with trace to few fine to medium-grained sand-sized shell and trace to little silt. Clay and silty sand, with increased shell size and percentage, was recovered in core borings outside of the vertical and horizontal limits of the borrow area.

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

Carbonate – Soil component that reacts with HCl of an indeterminate origin (shell, rock, etc.).

Fill – Material that has been placed by man, described with all soil characteristics.

Layer – Rock or soil with a thickness of 6 inches or less.

Lens – A geologic deposit of variable thickness, which disappears laterally in all directions and cannot be correlated to adjacent borings.

Rock – A naturally occurring substance composed of one or more minerals bound together. This geologic term includes a range of engineering properties: strength, hardness, permeability, weathering, and discontinuity. These properties are noted or can be inferred from the boring logs as blow counts, penetration rate, RQD, hardness, etc.

Shell – Material composed of predominantly (>75%) coarse-grained sand to gravel-sized whole or broken shell.

4.3 BORING LOG NOTES

Borings CB-DUC03-24 and VB-DUC13-B2-2 through VB-DUC13-B2-33 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 that was advanced until a depth of 20 feet was reached or 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.

4.5 BORING LOGS

Applicable boring logs are presented on the following pages.

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.
