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 REGIONAL AND LOCAL GEOLOGY

Sarasota County is within the Coastal Lowlands physiographic region of peninsular Florida. The topography reflects the marine terrace deposits origin, formed during the Pleistocene, when sea level rose and fell in response to the advance and retreat of the continental ice sheets. The melting of the last glacial event, starting approximately 20,000 years ago, marked the beginning of the Recent (in geologic time, the Holocene Epoch). The resulting rise in sea level slowed approximately 7,000 years ago, just below present sea level. At this time, barrier islands of west peninsular Florida began to form, and prograded eastward with continued sea level rise to the present position. The Quaternary sediments overlie the karst surface of Miocene Hawthorne Group limestones, sediments, and erosional features of the west Florida continental shelf.

2.2 MATERIALS ENCOUNTERED

Venice Inlet and cut S-20 were dredged historically multiple times to 9 feet Mean Lower Low Water (MLLW) plus 2 feet overdepth. The last dredging event was in 2009 and the materials to be excavated consist of shoaling that has occurred since the channel was last dredged. Cuts S-16 and S-17 were never dredged since the initial construction in the 1960s.

Vibracores were collected in January 2018 to characterize the material to be dredged. The boring locations are depicted in Plate 2 and listed in Table 1. Laboratory testing results are summarized in Table 2. Boring logs and laboratory testing data sheets are included in paragraphs 4.5 and 4.6, respectively

Gulf Intracoastal Waterway - Caloosahatchee River to Anclote River

00 31 32 - 3

The encountered sediments within the dredging depth consist of poorly graded, mostly sand-sized quartz with various amounts of sand to gravel-sized shell and shell fragments, and trace to little silt. Silt is occasionally present in the overdepth.

Any in-situ rock, if encountered, is not required to be dredged. Trash and debris are present in the materials to be dredged.

3 DEFINITIONS

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

3.1 DEFINITIONS OF BASIC TERMS

Carbonate – Soil component that reacts with HCl of an indeterminate origin (shell, rock, etc.).

Fill – Material that has been placed by man, described with all soil characteristics.

Layer – Rock or soil with a thickness of 6 inches or less.

Lens – A geologic deposit of variable thickness, which disappears laterally in all directions and cannot be correlated to adjacent borings.

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.

4.3 BORING LOG NOTES

All Borings were sampled using an electrical vibracoring machine that was housed on a 35-foot vessel. A generator with an electrical vibrator was attached directly to a three-inch diameter galvanized sample barrel and lowered to the sea floor through a moon pool in the deck of the sampling platform by attaching lengths of drill stem. The sample barrel was allowed to penetrate the sea floor until it reached the target depth 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. The vibracore apparatus is equipped with a graph-type depth of penetration recorder.

4.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1. is available for inspection by prospective offerors at the Corps of Engineers District warehouse listed below:

Address: 3077 Talleyrand Avenue Jacksonville, 32206 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) Project title;

(2) Specific borings or entire set which are to be viewed;

(3) Date, time, and duration of the visit;

(4) Name of the person(s) and company to view the borings; and

(5) 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.

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.
