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 and surface samples. 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 Geosystems Branch.

2 CHARACTER OF MATERIALS

2.1 THE LOCAL GEOLOGY

The local geology of the project area is characterized by Pleistocene and Holocene age, marine terrace and beach ridge sediments, which were deposited on an irregular and undulating surface.

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, the Pliocene age Cypresshead Formation is encountered which typically consists of tan or light gray quartz sand, shell, and clayey sand/sandy clay. The Miocene age Charlton Member of the Coosawhatchie Formation underlies the Pliocene age sands in the project area. Contained within the Hawthorn Group, the Charlton Member includes limestone, dolostone, clay, and phosphates. The thickness of the Miocene age Charlton Member and the Pliocene age deposits ranges from as little as 25 feet to more than 130 feet in the project area.

The Miocene age Hawthorn Group consists mainly of dark gray and olive green sandy to silty clay, clayey sand, clay, sandy limestone, and dolostone. The lithology of the unit is distinguished by the presence of significant percentages of black phosphate sand, granules, and pebbles. The Hawthorn Group ranges in thickness from about 250 feet to as much as 500 feet in the project area.

2.2 MATERIALS ENCOUNTERED

Jacksonville Harbor has been dredged, historically, multiple times for maintenance and deepening. Cut-3 through Cut-17 were last maintenance dredged in 2023 for the second time after

Maintenance Dredging

SECTION 00 31 32.20-3

the most recent deepening. Cobble to boulder size rocks were encountered at the southside of the channel in Cuts 9-11 during the last maintenance dredging event.

Vibracore and SPT/core borings are included in the GDR to characterize the material to be dredged. Vibracores were collected in 2020 and 2022 after the deepening. The borings show the shoaling material above the design depth. However, this material was removed during the prior maintenance dredging events. Nevertheless, the boring logs can be used to characterize the material to be dredged since similar material is anticipated to have shoaled in since.

The material above the design depth shown on the core boring and vibracore boring logs drilled in 2014 and 2016, respectively, was removed during the deepening. Those boring logs show the material still present beneath the overdepth and in the side slopes which can slough into the channel. Thus, those boring logs give important information about the dredging.

Based on the boring logs and previous dredging events, the shoaling material consists of poorly-graded quartz sand (SP), and sand with silt (SP-SM) with varying amounts of sand to gravel-sized shell. Gravel to boulder-size rock, silt and clay layers, clay balls, and oyster shells are also present in the material to be dredged.

Additionally, there will be material in the channel dredge template that sloughed in from the side slopes, containing gravel to boulder-size rock fragments, clay balls, and remnants of relict oyster beds. The overdepth will also contain gravel to boulder-sized rock fragments and stiff clays remaining from channel deepening. Any in situ rock, if encountered, is not required to be dredged.

This is an active navigation channel. Trash and debris, such as ropes, anchors, aluminum cans, plastic bottles, etc. from navigation activities are present in the materials to be dredged.

All sampling locations are depicted on Plates 2 and 3 with boring locations listed in Tables 1 and

2. Laboratory data for the project is summarized in Table 3.

4.3 BORING LOG NOTES

Borings of the CB-JH14- series 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 PQ wireline core barrel until the rate of penetration indicated softer material, at which point the SPT procedure was resumed.

All vibracore borings were sampled using an Alpine style, pneumatic vertical hammer, vibracore drilling apparatus having a continuous 20-foot or 10-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.

SECTION 00 31 32.20-11

4.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Tables 1 and 2 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 seven (7) 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.

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 maintenance and deepening 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. .
