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 1.4.6 and 1.4.7, 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 The Regional and Local Geology

Jacksonville Harbor Entrance Channel and the surrounding vicinity fall within the coastal lowlands physiographic division of northeast Florida, which runs parallel to the coastline and extends from the Atlantic Ocean to just west of downtown Jacksonville.

The regional geology of the Jacksonville Harbor Entrance Channel area is characterized by Holocene to Upper Miocene age undifferentiated surficial deposits underlain by sediments of the Hawthorn Group, and followed by Eocene siliciclastic sands and marine carbonate sediments.

The undifferentiated surficial deposits are composed of Holocene to Pleistocene age (recent to 2 million years ago), marine terrace and beach ridge sediments consisting of sands, silts, clays, and shell beds, and Pliocene/Upper Miocene age(2 to 10 million years ago), tan or light gray sand, shell, sandy clay, and limestone. Those sediments are approximately 70 feet thick.

Underneath the undifferentiated surficial deposits follow the sediments of the Miocene age Hawthorn Group(10 to 20 million years ago). The

Jacksonville Harbor Deepening 47-foot Project, Contract A

Section 00 31 32-3

Hawthorn Group consist mainly of dark gray and olive green sandy to silty clay, clayey sand, clay, and sandy limestone, and contain moderate to large amounts of black phosphate sand-size 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 occurs at depths ranging from approximately 50 to 200 feet below land surface throughout Duval County.

1.2.2 Materials Encountered

The materials to be dredged are characterized from historic and recent core and vibracore borings from 1980 through 2014. Boring locations are depicted in Plate B-1 through B-2 and listed in Tables 1 and 2.

Laboratory index testing results are presented in Table 3, sedimentation rate data in Table 4.

A marine resistivity survey was conducted for the entire Jacksonville Harbor Channel in 2009. The Resistivity Survey Report is attached in paragraph 1.4.8.

Jacksonville Harbor has been maintenance dredged historically multiple times. The current design template reaches to -40 feet MLLW plus 2 feet allowable over depth. The material shown to this depth presented on the boring logs and sediment gradation curves has been removed by previous dredging events with subsequent shoaling of similar materials.

Within the deepening template, the material recovered from the borings and depicted on the borings logs consist of poorly-graded quartz sand (SP), sand with silt (SP-SM), silty sand (SM), and clayey sand with varying amounts of sand to gravel-sized shell, including oyster shell underlain by clay and silt. Multiple feet thick shell and oyster shell beds have been encountered in the past and are expected to be present within the dredge template. The sand/clay contact is undulating and the clay usually starts below -50 feet MLLW, but there are several areas were clay is present as high as -44 feet MLLW. The clay and silt is of firm consistency and has a high plasticity.

Trash, debris, large oyster shells and rock fragments were encountered during previous dredging events and are present in the materials to be dredged. The last 2 dredging events of Cuts 3-5 has dredged up notable amounts of organic wood debris that has required cleanup from the beach.

1.3 DEFINITIONS

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

1.4.4 Boring Log Notes

Borings CB-MPJ08-11, CB-JHPM09-29 through CB-JHPM09-34, CB-JH14-094 CB- JH14-095, CB-JH14-097; CB-JH14-099 through CB-JH14-120, CB-JH14-122, CB- JH14-123, CB-JH14-125, and CB-JH14-127 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

Jacksonville Harbor Deepening 47-foot Project, Contract A

Section 00 31 32-12 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 VB-JHB2014M-9 through VB-JHB2014M-14, VB-MPH08-26, VB-MPH08-29, and VB-MPH08-30 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.

1.4.5 Recovered Materials

The material recovered from borings CB-MPJ08-11, CB-JHPM09-29 through CB-JHPM09-34, CB-JH14-094 CB-JH14-095, CB-JH14-097; CB-JH14-099 through CB-JH14-120, CB-JH14-122, CB-JH14-123, CB-JH14-125, and CB-JH14-127, and VB-JHB2014M-9 through VB-JHB2014M-14 is available for inspection by prospective offerors at the Corps of Engineers District warehouse listed below:

Address: 3077 Talleyrand Avenue Jacksonville, 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 904-232-1890 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) the project title; (2) the specific borings or entire set which are to be viewed; (3) the date, time, and duration of the visit; the name of the person(s) and company to view the borings; and (5) a 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.

1.4.6 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.
