1.1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of borings and grab samples. The associated boring and grab sample logs, and the 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 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 CHARACTER OF MATERIALS

1.2.1 Regional and Local Geology

Much of Florida's surface is covered by a series of interbedded limestone, dolostone, sand and clay units ranging from Eocene to Holocene Epoch.

The local geology of Hillsborough Bay consists of an uppermost layer of undifferentiated Quaternary Period sediments - comprised of silici-clastic, organic sediments and freshwater carbonates. Those sediments range in thickness from approximately 30 to 80 feet and are underlain by the 50 ft. to 330 ft. thick, Oligocene/Pliocene deposits of the Hawthorn Group consisting of phosphatic siliciclastics (sand, silt and clay) and carbonates. Underneath the Hawthorn group are limestones and dolostones of the Ocala Limestone and Eocene Avon Park Formation present.

1.2.2 Materials Encountered

Tampa Harbor has been dredged for maintenance historically multiple times. The last maintenance dredging event for Cut-A(HB) and Cut-C(HB) was in 2011 and for Cut-D(HB) in 2012.

Tampa Harbor, Maintenance Dredging, 43-Ft, 41-Ft, & 34-Ft Projects

00 31 32-3

The materials to be dredged are described on logs and gradation curves from grab samples collected in 2011 and 2012, and one vibracore boring collected in 2014. The grab samples located in Cut-A(HB) were collected before the dredging event in 2011, and the grab samples in Cut-D(HB) were collected before the dredging event in 2012. Therefore the materials presented on the grab sample logs and respective sediment gradation curves have been removed with subsequent shoaling of similar materials thus providing still valid information about the materials within the dredge template. Vibracore Boring VB-HBC14-1 was collected in 2014. The material from this boring has not been removed. The elevation of this boring is 43.9 feet MLLW, which is below the design depth but within the overdepth.

Based on historic knowledge, and the historic and recent sediment samples, the material to be dredged is composed of silty sand, silt and clay. Various amounts of sand-sized shell are present in the silty sand. Trash and debris such as for example ropes, anchors, beer cans, and plastic bottles are present in the materials to be dredged.

The project site vicinity is depicted on plate B-1 and sampling locations on presented on Plates B-2 and B-3 and listed in Table 1 and

2. Laboratory data for the project area is summarized in Table 3.

1.4.3 Boring Log Notes

Boring VB-HBC14-1 was sampled using an Alpine style, pneumatic vertical hammer, vibracore drilling apparatus having a continuous 20-foot by 3 or 3 1/2-inch core barrel with clear plastic core liner until refusal was encountered. Refusal is defined as no additional penetration of the vibracore with two minutes of additional effort applied to penetrate through the resistant layer at maximum vibration.

All grab samples were taken with an AMS 6”x6”x6” clam shell sampler which weighs approximately 25 pounds. The sampler was tied to nylon rope and mounted on a shipboard winch with pulley. During sampling, the clam shell was allowed to free-fall from the winch at the target location.

1.4.4 Recovered Materials

The grab sample material is not available for inspection.

The material recovered from boring 'VB-HBC14-1 is available for inspection by prospective offerors at the Corps of Engineers District warehouse:

Address: 3077 Talleyrand Avenue Jacksonville, 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 904-232-1890 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) the project title; (2) the specific borings or entire set which are to be viewed; (3) the date, time, and duration of the visit; the name of the

Tampa Harbor, Maintenance Dredging, 43-Ft, 41-Ft, & 34-Ft Projects

00 31 32-9 person(s) and company to view the borings; and (5) a 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.

1.4.5 Boring Logs

Applicable boring logs are presented on the following pages.

The grab sample logs presented in this section are available historic information within the project area. Most of the materials within the project template presented on the logs and graphs have been removed by previous dredging events with subsequent shoaling of similar materials.

The current elevations of the materials at these locations are shown on the contract drawings.

While the Government’s borings and grab samples 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.
