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 are presented in paragraph 1.4.5. Laboratory testing data are presented in paragraph 1.4.6, and vibracore penetration reports in paragraph 1.4.7. 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

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 Pleistocene age, undifferentiated surficial deposits underlain by the Pliocene age, Cypresshead Formation. The undifferentiated surficial deposits are composed of marine terrace and beach ridge sediments consisting of sands, silts, clays, and shell beds, while the Pliocene age Cypresshead Formation consists primarily of reddish brown to reddish orange sands and clayey sands with more isolated lenses of silt and clay. The total thickness of the Holocene to Pliocene age sediments is approximately 50-100 feet.

The Cypresshead Formation is underlain by sediments of the Hawthorn Group, primarily Miocene in age. The Hawthorn Group consists mainly of dark gray and olive green sandy to silty clay, clayey sand, clay, and sandy limestone. Low to moderate amounts of black to brown, sand to granule-pebble size phosphate are present in most lithologies within the Hawthorn Group. The unit ranges in thickness from about 250 feet to as much as 500 feet. Although the Hawthorn Group thickens generally to the northeast, it varies in thickness due to irregular upper and lower formation boundaries.

Materials Encountered

Jacksonville Harbor Entrance Channel Cut-3 through Cut-17 has been deepened to -47 feet plus two feet overdepth and some areas additionally 2 feet of advanced maintenance. This is the initial maintenance event for Cut-3 through Cut-17 after the recent deepening. Vibracores were

FY21 Jacksonville Harbor O&M Dredging 47-foot Project

SECTION 00 31 32.20-3

collected in May 2020 to characterize the material to be dredged. The recently collected data is supplemented by historic vibracore borings from 2014 and 2016 and core borings from 2014 and 2018.

Boring locations are depicted on Plates 1 through 4 and listed in Tables 1 and 2. Laboratory index testing results are presented in Table 3.

Trash and debris, were encountered during previous dredging events and are present in the materials to be dredged.

1.2.2.1 Materials Encountered: High Spot Removal Area

The material encountered at the high spot removal area is in-situ material and consists of poorly graded fine to medium-grained sand-size quartz (SP) with various amounts of sand to gravel sized shell, and clay with various amounts of sand-sized quartz, and sand to gravel-sized shell.

1.2.2.2 Materials Encountered: Cut-3 through Cut-17

The material encountered in cut-3 through cut-17 is shoaling material and material sloughing in from the side slopes. The shoaling material consists of poorly-graded quartz sand (SP), sand with silt (SP-SM) and silty sand (SM) with varying amounts of sand to gravel-sized shell, including oyster shell. The material sloughing in from the side slopes will additionally contain 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 the channel deepening. Any in situ rock, if encountered, is not required to be dredged.

1.3 DEFINITIONS

Definitions of Basic Terms

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.

Shell – Material composed of predominantly (>75%) coarse-grained sand to gravel-sized whole or broken shell.

Boring Log Notes

All vibracore 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 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.

All core borings 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

FY21 Jacksonville Harbor O&M Dredging 47-foot Project

SECTION 00 31 32.20-10

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.

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.

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.
