1.1 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 1.4.5 and 1.4.6, 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.

1.2 CHARACTER OF MATERIALS

1.2.1 Local Geology

Collier County is located in southwest Florida and covers approximately 2,032 square miles. Its boundaries are formed by Lee and Hendry Counties, on the north, and Monroe County on the south. The shoreline of Collier County is characterized by sandy barrier islands backed by shallow bays, marshes, and mangrove areas. Collier County lies within the Atlantic Coastal Plain physiographic province and is part of the terraced coastal lowlands physiographic region. The terraced coastal lowlands were formed during the Pleistocene epoch when a series of glacial periods, or ice ages, brought about drastic changes in sea level. As a result of these sea level fluctuations, the Florida peninsula was alternately covered and uncovered by shallow seas. During periods of high sea levels large amounts of sediment were deposited, such as the Pamlico Sand which underlays the recent coastal sediments in Collier County. The Pamlico Sand is composed of fine to medium grained quartz sand and is 10-15 feet thick. Underneath those sediments, hard limestone of the Anastasia Formation is present.

SECTION 00 31 32-3

1.2.2 Materials Encountered

GIWW Naples Gordon Pass has been dredged historically multiple times.

The last dredging event was in 2009. The borings include in this GDR were collected in 2008. Therefore the materials presented on the boring logs and sediment gradation curves have been removed with subsequent shoaling. However, the historic boring logs provide still valid information about the materials in and below the dredge template and they indicate what type of dredge material can be expected.

Based on materials encountered during previous dredging events and the historic borings, the materials to be dredged consist of poorly-graded quartz sand with variable amounts of silt and gravel-size to sand-size shell fragments. Trash and debris may be present in the materials to be dredged.

The project site vicinity is depicted on plate B-1. All sampling locations are depicted on Plate B-2 and listed in Table 1. Laboratory data for the project area is summarized in Table 2.

1.3 DEFINITIONS

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

1.3.1 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.

Borings VB-NGP08-1 through VB-NGP08-6 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 material recovered from borings VB-NGP08-1 through VB-NGP08-6 is not available for inspection.

1.4.5 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.
