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 and test pits. The associated boring logs and laboratory data are presented in paragraphs 5.5 and 5.6, 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 PROJECT BACKGROUND

The project consists of two features: constructing an upland dredged material management area O-23 (DMMA O-23) and modifying the stormwater system for Martin County Business Park in Martin County, Florida. The disposal area dikes shall be constructed using fill material excavated from within the containment basin footprint. Twin steel-framed box riser weirs with composite weir boards are to be constructed to provide the site decant water system. The stormwater modification consists of constructing three detention ponds, replacing manholes and catch basins, and installing control structures. Other features of work include clearing and grubbing, fencing, and slope protection.

3 CHARACTER OF MATERIALS

3.1 REGIONAL GEOLOGY

Martin County falls within the Atlantic Coastal Province physiographic unit and is part of the Eastern Flatland Region which was formed during the inundation and subsidence of recent ice ages and the respective oceanic submergence and emergence. The surficial sediments consist of sands, silts and clays of Holocene to recent age. Those surficial deposits are underlain by the Anastasia formation, which is composed of interbedded sands and coquina limestone. The coquina limestone is almost entirely comprised of whole and fragmented mollusk shells, is lightly to moderately indurated and of orange-brown color. The interbedded, unconsolidated to lightly-cemented sand layers are gray to orange-brown in color and can contain fossils. The Anastasia Formation is followed by the sediments of the Pleistocene-age Fort Thomson formation and subsequently by the Pliocene Tamiami Formation. Lithologically these sediments are varying from unconsolidated fossiliferous quartz sands to well-indurated, sandy, fossiliferous limestone. Clayey sands and sandy clays are also present. The Pleistocene and Pliocene sediments have a thickness of 50 to 200 feet and form part of the surficial aquifer system.

3.2 THE LOCAL GEOLOGY

The county soil survey describes the general on-site soil and groundwater conditions. Moderately well drained Jonathan Sand is the predominant native soil found on site, with poorly drained Salerno Sand found in a narrow band along the railroad right-of-way that forms the site's southeastern boundary, as well as in the site's southwestern corner. The site's western one-third is wooded. A small (0.2-ac) wetland, classified as mixed wetland forest, lies in the site's extreme southwestern comer adjacent to the railroad right-of-way.

3.3 MATERIALS ENCOUNTERED

The geotechnical investigation consisted of nine (9) standard penetration test (SPT) borings and three (3) test pits, thirteen (13) recharge tests, and three (3) percolation tests.

3.3.1 Interior of DMMA (Borrow Area)

Two (2) test pits were excavated in the interior of DMMA O-23 to a depth of 15 feet below ground surface (bgs). The materials encountered in the test pits consist of predominantly poorly-graded fine to medium-grained sand-sized quartz with few silt.

3.3.2 Dike Alignment

The subsurface investigation consisted of one (1) test pit, excavated to a depth of 15 feet bgs, and eight (8) SPT borings, drilled to a depth of 45 to 60 feet bgs, along the proposed perimeter dike of DMMA O-23. The subsurface investigations show the materials encountered consist predominantly of poorly-graded fine to medium-grained sand-sized quartz with occasional sand to gravel-sized shell fragments, and few to some silt.

3.3.3 Staging Area

One (1) SPT boring was drilled in the northwest corner of the site, in the vicinity of the staging area. The subsurface investigations show the materials encountered consist predominantly of poorly-graded fine to medium-grained sand-sized quartz with occasional sand to gravel-sized shell fragments, and few to some silt.

5.3 BORING LOG NOTES

Borings CB-DMMAO23-17-01 to CB-DMMAO23-17-09 were driven using the Standard Penetration Test (SPT) procedure using an ATV mounted CME 45 drill rig 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.

Test pits TP-DMMAO23-17-01 to TP-DMMAO23-17-03 were excavated using a backhoe.

5.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1 is available for inspection by prospective offerors at the Corps of Engineers District warehouse. The address and hours of operation for the warehouse are listed below:

5.5 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.
