GEOTECHNICAL DATA REPORT

1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of vibracores. The associated vibracore 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 vibracore 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 THE LOCAL GEOLOGY

Sediments of the Pleistocene Age (15,000 to 50,000 years BP) and Holocene Age (present to 15,000 years BP) were deposited during the formation of marine terraces and beach ridges. These sediments blanket all of Duval and Nassau Counties. 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 portions of the Counties. The deposits are thickest below ridges and in places where they overlie depressions in the surface of the upper Miocene or Pliocene deposits.

The surficial 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 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.

2.2 MATERIALS ENCOUNTERED

The IWW – Vicinity of Sawpit Creek has been dredged to the maximum authorized depth with allowable over-depth several times; the most recent dredging event occurred in 2013. Therefore, all shoaled materials are newly deposited in the channel through normal coastal processes occurring in and around inlets. As such, all of the recent vibracore logs were collected prior to the last dredging event, but are representative of the shoaled material.

Maintenance Dredging 12-Foot Project AIWW - Vicinity of Sawpit Creek

00 31 32 - 4

The materials encountered within the dredging template for Cuts 23 to 27D are shoaled materials represented by vibracores collected in 2008. The materials to be encountered primarily consist of poorly graded, fine-grained sand-sized quartz, silty sand or poorly-graded sand with silt, and whole and broken angular shell fragments ranging in size from sand to gravel-size.

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.

4.3 BORING LOG NOTES

All vibracore borings were sampled using an Alpine style, pneumatic vertical hammer, vibracore drilling apparatus having a continuous 10-foot by 4-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.

4.5 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.
