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 0 and 4.6. A character of materials paragraph is included to provide a comprehensive description of the materials utilizing recent 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 THE LOCAL GEOLOGY

The local geology is recent artificial fill, swamp deposits, and alluvium. Artificial fill includes man-made debris, concrete, waste, sand to gravel sized rock and wood fragments, limestone, and volcanic rock. Swamp deposits, which are generally less than 15 feet thick, include sandy organic fine-grained deposits and clayey sand. The alluvium, generally less than 30 feet thick, is described as sand, clay, and sandy clay. The alluvium is derived from the physical and chemical disintegration of Tertiary sedimentary formations (Mucarabones Sand, San Sebastian Formation and Rio Piedras Siltstone) exposed along the Quebrada Margarita up to the headwater between the municipalities of Guaynabo and San Juan.

The alluvium deposits are underlain by Rio Piedras Siltstone of Eocene and Paleocene ages which are characterized by thin bedded siltstone containing thin layers of clay stone and calcareous sandstone. Near Bechara Industrial area the Aymamón and Aguada limestone formations of Middle Miocene age underlay the alluvium deposits. Geologic descriptions of outcrops in the area show hard, cavernous limestone to poorly cemented limestone. Both of which contribute to the karst of northern Puerto Rico.

2.2 MATERIALS ENCOUNTERED

The materials to be dredged were characterized from vibracore borings taken in 2018.The materials primarily consist of silty sand, silt and clay with varying amounts of organic material, sand to cobble sized whole and broken shell and rock fragments are expected to be encountered.

3 DEFINITIONS

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

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.

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.
