Geotechnical Data Report

1.1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of borings and wash probes. 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 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

The study area is located within the shallow marine shelf that surrounds the Commonwealth of Puerto Rico. Sediments of Holocene to and Pleistocene overlie limestone of Tertiary age. The limestone is found at depths varying from 40 feet to more than 100 feet in depth. Periods of fluctuating sea levels occurred during the glacial periods at the close of the Tertiary exposing the limestone allowing for weathering and erosion to occur. Sediments including silt and clay were deposited on the bottom of San Juan Harbor in the final glacial melt. Shallow lagoons formed in depressions along the coast. Silt and clay were and still are transported from upland areas by streams and are deposited into the San Juan Harbor.

1.2.2 Materials Encountered

San Juan Harbor has been dredged historically multiple times with the last maintenance dredging event in 2011. Therefore the materials presented on the boring logs and sediment gradation curves prior to 2011 have been removed with subsequent shoaling of similar near surface materials. Nevertheless, the historic boring logs included in this GDR give still valid information about the materials below the dredge

San Juan Harbor Maintenance Dredging, 30 Foot Project, SECTION 00 31 32.10 Page 3 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, the historic borings, and the grab samples collected during fall 2015, the materials to be dredged consist primarily of soft fat clay and silt with trace amount of sand that has been deposited since the last dredging event. Limestone is shown on the historic boring logs within the dredge template of the Army Turning Basin and the West Cruise Ship Channel.

The rock has been removed during the last deepening event, however sand to boulder-sized rock fragments can be encountered in the shoal material along the channel slopes and in the overdepth. The same is applicable for the stiff clays which have been removed during the last deepening event; left-over spots can be present in the overdepth.

In-situ rock, if encountered, is NOT required to be dredged. Debris such as ropes, tires, anchors, scrap metal, wood and other trash are present in the shoaled material throughout San Juan Harbor.

An overview map is include as Plate B-1. Boring locations are presented in Table 1 and are depicted in Plate B-2 and B-3, and Grab Sample locations are presented in Table 2 and are depicted on Plate B-4 and B-

5. Available laboratory testing is presented in Table 3.

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.

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.

1.4.3 Boring Log Notes

Borings were drilled using one of two methods. They 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.

The second method used to drill the borings was using a 5 foot sampler with a procedure similar to the Standard Penetration Test (SPT). The blow counts indicated are those required for sampling only and do not correlate to the N-values of a SPT. Clamshell bucket was used on select borings to obtain samples of the softest material found at the top of the boring. Those borings in which a 5 foot sampler or the clamshell bucket was used are noted on the boring logs.

1.4.4 Recovered Materials

The material recovered from the borings and grab samples is not available.

1.4.5 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. The materials within the project template presented on the boring logs have been removed by previous dredging events with subsequent shoaling of similar near surface 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.
