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 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 surficial geologic deposits of southeast Florida are the Miami, Key Largo, Anastasia, and Fort Thompson Formations. These limestone formations were deposited in shallow Pleistocene seas.

The Fort Thompson Formation is the oldest formation and was deposited in warm shallow seas similar in environment to the broad barren marine plains covering the Bahamas Banks today.

Later, coral reefs of the Key Largo Limestone created a shelter behind which the bryozoan facies of the Miami Limestone formed. Later broad shoals of oolitic sediments were deposited along the coast.

The Anastasia and the Miami Formations were formed as sand shoals and beach ridges 100,000 to 125,000 years ago (Shinn, 1988). Tidal channels cut through the carbonate and oolitic shoals, connecting the shallow sea covering the Everglades with the Atlantic Ocean. These channels form the parallel cuts known today as the Transverse Glades in Dade County (Hoffmeister, 1974).

The topography of Palm Beach, Broward and Dade counties are dominated by Lake Okeechobee, the Everglades, sandy flatlands, the Atlantic Coastal Ridge, coastal lagoons, and the modern barrier islands

The Atlantic Coastal Ridge extends along the Atlantic coast as an irregularly shaped highland composed of broad marine plains, beach ridges and bars. North of Boca Raton, the Anastasia Formation forms the backbone of the Atlantic Coastal Ridge. South of Boca Raton, the Atlantic Coastal Ridge is formed by the Miami Oolite.

Broward County is geologically divided into the Everglades to the west, the heavily populated Atlantic Coastal Ridge on the east, the barrier islands, and nearshore deposits. The barrier islands and the nearshore deposits are underlain by the Miami Limestone. The nearshore shelf off Broward County is characterized by 3 step-like plateaus, each lower than its immediate shoreward neighbor, and separated by irregular, rock reef ridges (Duane and Meisburger, 1969).

The plateaus were created by sediments filling depressions located between the rock ridges.

Each reef grew offshore during a different lower stand of sea level.

2.2 MATERIALS ENCOUNTERED

This reach of the IWW has not been maintained since it was originally constructed in approximately 1965 due to low shoaling rates and the ability to naturally maintain the authorized depths. Dredging will occur in Reach 1 of the IWW channel adjacent to Hillsborough Inlet in Broward County and outside of the IWW channel adjacent to Reach IV for the purpose of accessing MSA-641A in Palm Beach County.

2.2.1 Reach 1, Broward County

The material to be encountered consists of fine- to medium-grained quartz sand, silty sand, and silt, with some sand to gravel sized shell material. Gravel size limestone fragments are recorded within the boring logs. Some wood and organic matter was recorded within the boring logs.

Peat is shown in boring logs VB-IWWBRW14-2 and VB-IWWBRW14-3; this material is below the project dredge depth and should not be removed.

2.2.2 MSA-641A Shoal, Palm Beach County

Taylor Engineering performed geotechnical analysis on the material to be encountered, and provided this data to the Government. The boring collected was adjacent to the IWW channel, not within the channel, and indicates the possibility of rock. In-situ rock, if encountered, is not required to be dredged. Additional information about this material is location in paragraph 4.7.

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 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.

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. 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.
