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 LOCAL GEOLOGY

Underneath a thin layer of recent deposited sediments, Pleistocene age Pamlico sands mantle almost all of Palm Beach County. The sand is gray or white and about 10 feet thick along the coastal ridge, and up to 50 feet in the dune areas. Pamlico sand is primarily quartz sand deposited during a higher stand of sea level and lies unconformably over the Anastasia Formation.

The Anastasia Formation is composed of sand, sandstone, limestone, coquina, and shell beds and underlies all of eastern Palm Beach County and reaches a thickness up to 200 feet beneath the coastal ridge.

2.2 MATERIALS ENCOUNTERED

The Palm Beach Harbor Entrance channel, Cut-1, Cut-2, Southern and Northern Turning Basin, and the Settling Basins have been dredged historically multiple times. The last maintenance dredging event of the entire Palm Beach Harbor was in winter 2017.

The Settling Basins were deepened to 35 feet Mean Lower Low Water (MLLW) in 2012.

Therefore, the materials presented on the boring logs and sediment gradation curves prior to 2012 have been removed with subsequent shoaling. However, the historic boring logs give still valid information about the materials below the dredge template and also show what type of material can be expected in the side slopes and possibly any collapse of side slope materials.

Based on materials encountered during previous dredging events and the historic and recent borings, the materials to be dredged consist primarily of poorly-graded quartz sand with variable amounts of silt and gravel to sand-sized shell fragments. Trash and debris were encountered during the last dredging event and are present in the materials to be dredged.

Palm Beach Harbor Maintenance Dredging

00 31 32-3

Since in-situ rock was encountered in the Entrance Channel, the Northern Turning Basin and the Settling Basins during the 2012 dredging event, sand to boulder-sized rock fragments are present within the shoal material along the channel and basins sides and in the overdepth. Any in-situ rock, if encountered, is not required to be dredged.

All sampling locations are listed in Table 1 and depicted on Plate 2 and Plate 3. Laboratory data for the project area is summarized in Table 2.

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.

Borings CB-PBH95-1, CB-PBH95-2, CB-PBH95-3, CB-PBH95-7, CB-PBH95-8, CB-PBH95-12, , CB-LWI13-3 through CB-LWI13-5, CB-LWI13-10 through CB-LWI13-14, CB-LWI13-16, CB- LWI13-18 through CB-LWI13-20 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 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.

CB-WP97-17 were driven using a 300 pound hammer with a 18-inch drop using a 2.0 foot split spoon similar to the Standard Penetration Test (SPT) procedure. The blow counts indicated are those required for sampling only and do not correlate to the N-values of a

SPT.

Borings PBVC-05-02, VB-LWI2012-04, VB-LWI2012-05,VB-LWI2012-07, VB-LWI2012-08, VB- LWI2012-11, VB-LWI2012-13, VB-LWI2012-15, VB-LWI2012-16, VB-LWI2012-17 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 that was advanced until a depth of 20 feet was reached 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.

4.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1 and Table 2 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 904-232-1890 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.

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 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. Accordingly, prospective offerors shall form their own conclusions from the examination of the recovered materials prior to submission of their offer.
