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, muck probes, and field permeability test data. The associated boring logs, field test results, and laboratory data are presented in paragraphs 5.1, 5.2, and 5.3. 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 PROJECT BACKGROUND

The project will construct culverts S-631, S-632, and S-633 within the L-67A levee. The L-67A levee is one of two seepage management levees that trend northeast to southwest to separate Water Conservation Areas 3A and 3B (WCA-3A, WCA-3B). The project objective is to construct three culverts within the L-67A levee to direct surface water flows eastward from WCA-3A to WCA-3B. Once constructed, surface water will flow in a controlled manner to equilibrate water levels in both WCAs, leading to more natural hydroperiods in these wetlands. Plate 1 and Plate 2 show the vicinity map, and project feature locations, respectively.

3 CHARACTER OF MATERIALS

3.1 REGIONAL AND LOCAL GEOLOGY

The project is located in an undeveloped area of south Florida, within the WCA-3A and WCA-3B.

The surficial geology consists of Holocene peat, an organic-rich soil that forms in wetlands. Peat is underlain by a thick sequence of marine limestones. The uppermost layer of limestone is a hard, weathered limestone, which is the upper weathered surface of the Fort Thompson Formation. The Fort Thompson Formation consists of superposed sequence of marine limestone, carbonate sands and silts, and thin freshwater limestones (marl) that were that were deposited during changing sea levels of the Quaternary Period. The Fort Thompson Formation thickness is approximately 70 feet in the project area, and thins to the west.

3.2 MATERIALS ENCOUNTERED

Three Standard Penetration Test (SPT) borings/cores were collected along the L-67A at the proposed culvert locations. L-67A levee materials consist primarily of sand- to boulder-sized carbonate rock with various amounts of shell, clay and silt. L-67A levee was constructed directly on top of peat and limestone. The limestone is moderately hard to hard, highly to slightly

00 31 32 - Page 3 weathered, and pitted to vuggy. The limestone varies in hardness as shown on the logs and can be underlain by sand as seen in borings CP20-S632-CB-01 and CP20-S633-CB-01. Where sampled, UCS tests show rock above 3300 psi. Rock strengths may be higher in the vicinity based on the natural variation of the rock. Due to the hard nature of the rock, pretreatment of the rock is needed. Boring locations are shown in Plate 2, and coordinates are shown in Table 1.

Boring logs are shown in Section 5.6.

4 DEFINITIONS

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

4.1 DEFINITIONS OF BASIC TERMS

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.

5.4 BORING LOG NOTES

Borings CP20-S631-CB-01, CP20-S632-CB-01, and CP20-S633-CB-01 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 3 3/8-inch core barrel until the rate of penetration indicated softer material, at which point the SPT procedure was resumed.

5.5 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. The address and hours of operation for the warehouse are 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 904-232-1236 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.

5.6 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.
