GEOTECHNICAL DATA REPORT

1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of surficial samples.

The associated laboratory data is presented in paragraph 4.4. A character of materials paragraph is included to provide a comprehensive description of the materials utilizing recent and historical knowledge of the project area.

When evaluating the subsurface conditions, use all of the data, including the character of materials paragraph and the laboratory data.

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 AND REGIONAL GEOLOGY

The subsurface in the vicinity of Manatee Harbor is comprised of a surficial layer of undifferentiated deposits which can reach up to 40 feet in thickness. Those deposits are composed of loose, fine to medium quartz sands, silty sands, and silts with shell deposits and are underlain by Pliocene sediments which were deposited on the undulating surface of the Hawthorn Group.

The Pliocene deposits vary in thickness from a few to up to 40 feet. They are composed of semi-indurated soft to firm sands, silty sands, clayey sands, clays, and silts. The sands are mostly fine to medium quartz with minor amounts of phosphate and varying amounts of shell. It is common for these materials to be interbedded with moderately weathered soft to hard sandstone, clayey limestone (marl), and hard-cemented silt. Typically the rock is less than 6-inches thick and discontinuous, however, some layers are as much as 2-feet thick.

The Hawthorn sediments found beneath the Pliocene sediments primarily consist of thick beds of indurated, firm to hard clayey sands, silty sands, clays and silts, interbedded with varying thicknesses of discontinuous sandstone, clayey limestone (marl), and siltstone.

2.2 MATERIALS ENCOUNTERED

The Manatee Harbor Dredge Material Management Area (DMMA) shown on Plate 1 is used to store dredged material from Manatee Harbor for decades. The dredged material from Manatee Harbor consists primarily of silt, stiff clay, silty sand, sand, and sand to boulder-size limestone fragments.

SECTION 00 31 32-3

The entire DMMA was completely submerged in March 2018. Dewatering activities were performed from July through August 2018. Twenty samples were collected on 29 August 2018 from the stockpiles and also from approximately 1 foot below the ground surface where material was sampled in-situ. The sample locations are listed on Table 1 and depicted on Plate 2. All samples were analyzed in the laboratory for grain-size and water content, and five selected samples for Atterberg limits. The lab results are summarized in Table 2 and the gradation curves are attached in paragraph 4.4.

The lab results characterize the material to be offloaded as silty and clayey fine-grained sand with little to some silt or clay, and trace to some sand to gravel-sized limestone.

The water content of the samples was 18-42%. Besides the type of material described from the samples, pockets of stiff clay, silt, and cobble to boulder-size limestone are present.

Since the samples were collected additional dredged material was placed within the site.

Furthermore, dewatering activities were performed throughout the site. The condition of the material is altered in the dewatering process. It is strongly suggested that prospective offerors visit the site to examine the current condition of the material before submitting their bid.

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.
