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 4.5 and 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.

2 CHARACTER OF MATERIALS

2.1 REGIONAL AND LOCAL GEOLOGY

The project site is located in the southwest corner of Martin County in the Everglades physiographic region. Below a thin layer of Holocene soils, undifferentiated Pleistocene quartz sands and clayey quartz sands with occasional sandstone layers are present. Those sediments can reach a thickness of up to 20 feet. These are underlain by marine sands, shell beds, limestone, or sandstone of the Pleistocene Caloosahatchee, Fort Thompson, and Tamiami Formations. The Pleistocene sediments are approximately 100 to 200 feet thick and lay unconformable above the deposits of the Hawthorn Group, which is composed of limestone, dolomite, shell, quartz sand, clay, and abundant phosphorite grains.

2.2 MATERIALS ENCOUNTERED

Eight standard penetration test (SPT) borings (CB-347, CB-348, and CB-383 through CB-388) and eight roto-sonic borings (CB-431 through CB-438) were drilled in 2005 and 2006 along the C-44 intake canal. The borings and inherent knowledge obtained during the construction of the C-44 Intake Canal in 2010-2012 indicate the materials encountered are composed of poorly graded sand, clayey and silty sand with shell fragments. Occasional clay, organic and hard sandstone and limestone layers of up to 5 feet were encountered during the construction of the canal and are present within the project limits.

The site was modified as part of Volume II in Contract No. 1, W912EP-11-C-0019, after the performance of the herein provided borings. During construction the intake canal slopes were cut into existing ground but may also have been reformed with placement of fill to meet final grade.

Typically canal excavation material was utilized as fill, in accordance with the Contract No. 1 Plans & Specifications construction contract docs. Description of “fill” is, in general, what’s depicted in the borings and any mixture in between. The encountered materials is primarily composed of

C-44 Reservoir/STA Project

SECTION 00 31 32 - 4

poorly graded clayey and silty sand with shell fragments. The thickness of the fill placed is as much as 8 feet above original grade toward the northern end of the canal and, as low as 1 foot of fill towards the southern end of the canal. Thin veneers of fill may exist on the canal slopes as a result of excavation procedures or slope re-grading from construction/operation of the canal.

The project site vicinity is depicted on plate B-1. All sampling locations are depicted on Plate B-2 and listed in Tables 1 and 2. Laboratory data for the project area is summarized in Table 3.

4.3 BORING LOG NOTES

Borings CB-347, CB-348, CB-383 through CB-388 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- and 24’ 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.

Borings CB-431 through CB-438 were driven with a Roto-sonic drill rig.

4.4 INSPECTION OF RECOVERED MATERIALS

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. Accordingly, prospective offerors shall form their own conclusions from the examination of the recovered materials prior to submission of their offer.
