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 and laboratory data are presented in paragraphs 1.4.5 and 1.4.6, 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.

1.2 CHARACTER OF MATERIALS

1.2.1 Local Geology

Lee County, in southwest Florida, covers approximately 803 square miles.

Its boundaries are formed by Charlotte County on the north, Hendry and Collier Counties on the east, and Collier County on the south. The shoreline of Lee County consists of a series of barrier bars broken by numerous inlets. The shoreline is further characterized by sandy barrier islands backed by shallow bays, marshes, and mangrove areas. The coastal plain in the vicinity of San Carlos Bay and Estero Bay is of low relief and low elevation. The Caloosahatchee, Peace, and Myakka Rivers all drain the estuary system. The barrier islands of Lee County are believed to have been initially formed around 4,400 years ago and prograded seaward. A reduction in the rate of Holocene sea level rise at that time, combined with a local sand supply and pre-existing topography, helped in the location and formation of the present barrier island chain.

1.2.2 Materials Encountered

Fort Myers Beach Harbor has been dredged historically multiple times.

The last dredging event was 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 slough in.

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

All sampling locations are listed in Table 1 and depicted on Plate B-2.

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

1.3 DEFINITIONS

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

1.3.1 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.

VB-FTM11-C4-1, VB-FTM11-C4-2, VB-FTM15-01 through VB-FTM15-03, and VB- FTM15-03B 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

Borings MP-08-V2 was 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 moonpool 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 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) 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.

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.
