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 sediments which occur in the project area are of Holocene and Pleistocene age (10 kya to 2.6 mya). These were deposited on an irregular and undulating surface during the formation of marine terraces and beach ridges and blanket all of Duval County. The thickness of these deposits can be up to 10 feet in the St. Johns River valley. The deposits are thickest below the ridges and in places where they overlie depressions. The deposits consist primarily of tan to yellow, medium to fine grained quartz sands, which are locally stained rusty brown or red due to iron oxide. Locally thin gray sandy clay beds, which contain occasional mollusk shells, are present, particularly near the coast.

Beneath these sediments follow upper Miocene or Pliocene (2.6 to 23 mya) deposits, consisting of tan or light gray sand, shell, sandy clay, and limestone. Due to the deposition on the irregular surface of the underlying Hawthorn Group, the thickness of the upper Miocene or Pliocene deposits ranges from as little as 10 feet to as much as 130 feet. There are no known exposures of the upper Miocene or Pliocene deposits in Duval County. However, dredge spoil indicates that the river may be incised into the deposits, particularly in east Jacksonville.

The underlying Hawthorn Group, of middle Miocene age, consists mainly of dark gray and olive green sandy to silty clay, clayey sand, clay, sandy limestone, and contains moderate to large amounts of black phosphate sand, granules, and pebbles. The Hawthorn Group ranges in thickness from about 250 feet to as much as 500 feet. Although the formation thickens generally to the northeast, it varies in thickness from place to place because of both an irregular upper and lower surface. The Hawthorn Group is not exposed in Duval County but occurs at depths ranging from approximately 50 to 200 feet below land surface throughout the county.

The sediments being dredged in this project are mostly the Holocene and Pleistocene deposits that are mentioned above. There are some known instances of rock within the project area, but it is not exposed, and is present below the project depths.

2.2 MATERIALS ENCOUNTERED

Recent investigations using core boring methods, surface samples, and historical knowledge of the project area were used to describe the character of the material to be dredged. The borings and surficial samples included in this GDR were collected in 2005, 2008, and 2009.

2.2.1 Sill

The sill consists of an aggregate concrete that is reinforced with rebar. Core borings CB- BIMC08- 4 and CB-BIMC08-5R were collected within the sill. The sill is set in sandstone and limestone, as described on the logs. See the plan drawings for additional information.

2.2.2 Channel

The material in the channel consists of shoaled material deposited since the last dredging event, and includes silt, clay, shell and fine to medium grained quartz sand in various thicknesses.

The materials presented on the boring logs and sediment gradation curves have been removed during previous dredging events. However, the boring logs still provide valid information about the materials in and below the dredge template and in the slopes and, thus, indicate what type of dredge material can be expected.

Based on past dredging events, occasional gravel to cobble sized pieces of moderately hard sandstone and limestone may be encountered at the base of the dredge limits. In-situ rock, if encountered, is not required to be dredged.

4.3 BORING LOG NOTES

Boring CB-BIMC08-3 and CB-BIMC09-28 were driven using the Standard Penetration Test (SPT) procedure with a 140 pound hammer with a 30-inch drop using a 2.0 foot split spoon (1 3/8-inch I.D. and 2-inch O.D.). Borings were advanced in 18-inch intervals, or until refusal was encountered. Refusal is defined as a total of 50 blows of the hammer within any 6- inch increment, a total of 100 blows within any 1-foot increment, or no observed advance of the sampler after 10 successive blows of the hammer. When refusal was encountered, the borings were continued with a 4-inch by 5 1/2-inch diameter core barrel until the rate of penetration indicated softer material, at which point the SPT procedure was resumed.

Borings CB-BIMC08-4 and CB-BIMC08-5R, located on the concrete sill, were also advanced with a 4-inch by 5 1/2-inch diameter core barrel.

Surficial sediment samplesGS-BIMC05-2 was collected with a clamshell sampler.

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.
