1.1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of borings and dilatometer testing. The associated boring logs and laboratory data are presented in paragraphs 1.5.6 and 1.5.7, 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 PROJECT BACKGROUND

The structural features that are part of Contract 2D Walls include the construction of a channel wall between the Confluence Wall of the Margarita Channel Improvements and the West Abutment of De Diego Bridge Modification. On the other side of the channel, a wall will be constructed from the East Abutment of the De Diego Bridge to Station 85+50 of the Margarita Channel.

1.3 CHARACTER OF MATERIALS

1.3.1 Regional Geology

The regional geology of the project area can be inferred from the Geologic Map of the San Juan Quadrangle, Puerto Rico, published by the U.S. Geological Survey in 1977 as Miscellaneous Investigations Series Map I-1010. Sediments on the north coast of Puerto Rico dip to the north and are truncated by erosion displaying progressively older rocks toward the center of the island. The basement rocks of early Tertiary to Cretaceous age are volcanic, volcaniclastic, clastic and metavolcanic rocks. Overlying the basement is an on-lapping sequence through the Pliocene with overlying Quaternary deposits including paludal, beach and

Rio Puerto Nuevo Flood Control Project CNT 2D Walls

Section 00 31 32-3 alluvium deposits. The uppermost Tertiary sediments are primarily limestone of varying quality.

1.3.2 Local Geology

At the project site, 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.

1.3.3 Materials Encountered

The subsurface investigations found within the project limits are illustrated on Plate 2. The uppermost materials on site are fill, which is found nearest the De Diego Bridge abutments and Expressway. This fill material is composed of yellowish brown fat clays and clayey gravel with varying amounts of sand and organic materials. The clays are of soft to medium stiff consistency and the clayey gravel is typically loose density, which can become dense when larger particles are encountered. Based on general knowledge of the area, large pieces of debris (boulders, rubble, wood, waste material) may be encountered within the fill layer. The borings indicate the fill as high as elevation 24 feet NGVD29 to as low as elevation of -5.5 feet and may vary upon location.

The fill is underlain by soft layers of both organic and inorganic clays, silts and occasional peat up to approximately elevation -6 feet NGVD29. These soft layers of clays, silts, and peat are locally interbedded with sands with varying amounts of fines approximately up to

3.0 feet thick.

Below the soft organic layers, stiff yellowish brown alluvial clays with varying amounts of fine to coarse sand and limestone gravel were found between approximate elevations 2.0 to -76 feet. These stiff clay layers are locally interbedded with medium to dense, fine to coarse sands, silty/clayey sands, and sandy clayey gravel.

Below the stiff clay layer, limestone derived saprolitic sand, clay, silt, and limestone is encountered from approximate elevations ranging

Rio Puerto Nuevo Flood Control Project CNT 2D Walls

Section 00 31 32-4 from -47 to -76 feet to the deepest boring of elevation -92 feet. The materials are highly variable and can have SPT blow counts from the single digits to refusal. No rock strength data have been collected from the borings.

Groundwater levels at the time of drilling ranged approximately between elevations 2.5 feet to -6 feet. Local variations in groundwater are expected.

1.4 DEFINITIONS

1.5.3 Summary of Additional Laboratory & Field Testing Data

Sedimentation rate curves were obtained for this data set. For testing results, see paragraph 1.5.7.

Triaxial testing results were obtained for this data set. For testing results, see paragraph 1.5.7.

Dilatomenter testing results were obtained for this data set. For testing results, see paragraph 1.5.7.

1.5.4 Boring Log Notes

Borings 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.

1.5.5 Recovered Materials

The material recovered from borings is not available for viewing.

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.
