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

2.1 THE LOCAL GEOLOGY

The shallow sediments on the upland adjacent to Kings Bay Inner Channel are typified as fine to medium-grained sands interbedded with silty and/or clayey fine sands that extend to a depth of at least 50 feet below ground level.

Kings Bay Naval Submarine Base is situated at the edge of a salt marsh. The present marshlands surrounding Kings Bay developed over the past several thousand years as sea level slowly rose to reoccupy the area behind the existing barrier islands. Marshland sediments anticipated to be part of the shoaled maintenance dredging areas consist primarily of current-borne sands, silts, and clays, in addition to a significant quantity of organic material contributed by indigenous plants and animals.

2.2 MATERIALS ENCOUNTERED

Special information regarding materials is provided in the Special Instructions paragraph of the Dredging Specifications, Section 35 20 23.

2.2.1 Channel O&M, Ranges E through I, Stations 31+800 through 48+175

The materials to be removed from the maintenance areas in the federal channel accumulated as a result of shoaling since the previous dredging and dredged materials descriptions are based on current and historical records. Depending on the location or depth, these materials will consist primarily of fine to medium-grained sand, silt, and clay, with smaller amounts of gravel sized shell and/or limestone fragments.

2.2.2 Special Feature Areas, to Include Magnetic Silencing Facility – North, Magnetic Silencing Facility – South, and Site Six – South

The materials to be removed by maintenance dredging from the special feature areas outside the federal channel are described by VB-KBIC13-03 (MSF – South), VB-KB15-49 (Site Six – South), and VB-KB15-61 (MSF – North); the material encountered accumulated as a result of shoaling since the previous dredging and dredged materials descriptions are based on current and historical records. Depending on the location and/or depth, these materials will primarily consist of silty sand, silt, and clay. Gravel sized shell and/or limestone fragments may also be present.

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.

4.4 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

00 31 32 - Page 11 vibration. The vibracore apparatus is equipped with a graph-type depth of penetration recorder but is was not functioning at the time the cores were collected.

4.5 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1 is available for inspection by prospective offerors at the Corps of Engineers District warehouse listed below:

Address: 3077 Talleyrand Avenue Jacksonville, 32206 Florida Hours: 7:00 am to 2:30 pm

The recovered materials will be available for inspection during normal business hours as noted above, except Federal holidays, during the entire bid period. Prospective offerors shall notify the project geologist at 904-232-1054 or Chief, Geology and Explorations Section at 904-232-1617 at least four (4) working days before the visit.

The following information will be required to schedule the visit:

(1) Project title;

(2) Specific borings or entire set which are to be viewed;

(3) Date, time, and duration of the visit;

(4) Name of the person(s) and company to view the borings; and

(5) Point of contact and phone number regarding the visit.

Prospective offerors shall record their material examination visit in a record book maintained at the inspection site.

It is strongly suggested that prospective offerors view the samples before submitting their bid.

4.6 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.
