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 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 Geosystems Branch.

2 PROJECT BACKGROUND

The Saint Francis Barracks Seawall Design consists of the following: a gravel “French” drain with weepholes along the entire 544-foot length of seawall, patch/fill large cracks/voids on the seaward face of the seawall, fill soil voids encountered landward of the gravel drain system with flowable fill, emplace a gutter drain system between the seawall and the Building #8 (aka the “JAG” building), cut 30 inches off porch slab in order to continue installation of the gravel trench drain system along the entire porch and building, apply coquina mortar mix on the seaward face of the existing seawall (the inferior construction wall segment), install through-wall soil anchor system, and apply coquina mortar mix onto the seaward face at the seawall corner for 25(+/-) feet in both directions (above the shotcrete wave-break).

3 CHARACTER OF MATERIALS

3.1 REGIONAL GEOLOGY

Peninsular Florida occupies a portion of the much larger geologic unit called the Florida Plateau.

Deep water in the Gulf of Mexico is separated from deep water of the Atlantic Ocean by this partially submerged platform nearly 500 miles long and 450 miles wide. In the last 200 million years, the plateau has been alternately dry land or covered by shallow seas. During that time, up to 20,000 feet of carbonate and marine sediments were deposited. There has been a tilting of the Florida Plateau about its longitudinal axis. As a result, the west coast is partially submerged, as indicated by the wide estuaries and offshore channels, while the east coast is correspondingly elevated, showing the characteristics of an emergent coastline.

During the last million years, a series of four glacial periods, or ice ages, brought about significant changes in sea level. As a result of these sea level fluctuations, the Florida peninsula has been covered and exposed.

Approximately 15,000 years ago, sea level began its most recent rise towards present sea level.

About 7,000 years ago, the sea level rose to about 30 feet below its present level. It was at this most recent sea level rise that the modern barrier islands of southeast peninsular Florida formed.

The primary components of the modern barrier island sand is quartz that has migrated southward along the Atlantic coast and the reworking of the Pamlico Sand that was previously deposited over the entire region. Much of the coastal sediments are carbonates locally produced by calcite producing plants and animals. Additional carbonate material is reworked materials from outcropping Pleistocene formations offshore (Duane and Meisburger, 1969).

3.2 THE LOCAL GEOLOGY

The project is located on the barrier beach on the Atlantic Ocean, in central St Johns County, in the Atlantic Coastal Plain physiographic unit. The regional geology of St. Johns County for the Quaternary and upper Tertiary Systems range in age from Recent to Pleistocene to Miocene age sediments. The Recent to Pleistocene age sediments are undifferentiated and cover the entire county and consist of fine to medium quartz sand and thin lenses of shell and clay of varying thickness. These beds are generally discontinuous and vary within short distances both horizontally and vertically. The shell beds thicken and can become consolidated along the coast and form coquina of the late Pleistocene Anastasia Formation. These sediments occur at land surface and have an average thickness of 50 feet. These deposits lie conformably with the sediments of the Upper Miocene/Pliocene sediments. The Miocene/Pliocene sediments are comprised of interbedded layers of marine, fine to medium sand, shell and green, calcareous, silty clay. These sediments vary in thickness (20-75 feet) throughout the county, and have an overall trend to thicken to the east.

3.3 MATERIALS ENCOUNTERED

The materials encountered within the construction footprint primarily consist silty sand and sand.

The materials are described as poorly graded, fine- to medium-size quartz sand with some silt, little sand to gravel-sized shell fragments, and trace organic matter.

Some of the materials encountered were placed as fill during previous construction and repair events. Debris may be present within the subsurface materials.

5.3 BORING LOG NOTES

Borings CB-1 and CB-2 were driven with a Geoprobe® 7822Dt drill rig 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.

Borings HA-1, HA-2, and HA-3 were sampled with a hand auger. Borings HA-4 and HA-5 were collected using a Geoprobe® 7822Dt drill rig.

Mud probes were completed at the 4 test locations. Initially they were pushed with a 1 1/4" PVC rod. Due to the limited penetration, the probes were reattempted with a 5/8" aluminum bar with similar results.

5.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1 and Table 2 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:

Address: 3077 Talleyrand Avenue Jacksonville, 32206 Florida

Hours: 7:00 am to 2:30 pm

The recovered materials will be available for inspection during normal business hours as noted above, except Federal holidays, during the entire bid period. Prospective offerors shall notify the project geologist at 904-232-1054 or Chief, Geology and Explorations Section at 904-232-1617 at least four (4) working days before the visit.

The following information will be required to schedule the visit:

(1) Project title;

(2) Specific borings or entire set which are to be viewed;

(3) Date, time, and duration of the visit;

(4) Name of the person(s) and company to view the borings; and

(5) Point of contact and phone number regarding the visit.

Prospective offerors shall record their material examination visit in a record book maintained at the inspection site.

It is strongly suggested that prospective offerors view the samples before submitting their bid.

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.
