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 THE LOCAL GEOLOGY

Underneath a thin layer of recent deposited sediments, Pleistocene age Pamlico sands are present in northern Dade County. The sand is gray or white and about 10 feet thick along the coastal ridge. Pamlico sand is primarily quartz sand and lies unconformable over the Miami limestone. The Miami limestone formed as the result of the drastic changes in sea level associated with recent glaciations or ice ages. Beginning some 130,000 years ago the Sangamonian Stage raised sea levels to approximately 25 feet (7.6 m) above the current level. All of southern Florida was covered by a shallow sea. Several parallel lines of reef formed along the edge of the submerged Florida plateau, stretching from the present Miami area to what is now the Dry Tortugas. The area behind this reef line was in effect a large lagoon, and the Miami limestone formed throughout the area from the deposition of oolites and the shells of bryozoans. Starting about 100,000 years ago the Wisconsin glaciation began lowering sea levels, exposing the floor of the lagoon. By 15,000 years ago, the sea level had dropped to 300 to 350 feet (110 m) below the contemporary level. The sea level rose quickly after that, stabilizing at the current level about 4000 years ago, leaving the mainland of South Florida just above sea level.

2.2 MATERIALS ENCOUNTERED

Historic vibracore borings VB-IWW06M-DA9-6 through VB-IWW06M-DA9-9, and VB-IWW08M- DA9-1 through VB-IWW08M-DA9-3 are located in cut DA-9 of the IWW Channel in the vicinity of Bakers Haulover Inlet. Most of the materials within the project template presented on the boring logs have been removed by previous dredging events with subsequent shoaling of similar materials.

Intracoastal Waterway Jacksonville to Miami, Florida, 00 31 32 - 3

The encountered sediments within the dredging depth consist of poorly graded, mostly sand-sized quartz and shell fragments with various amounts of gravel-sized shell and shell fragments. Only occasional layers of sand with silt and silty sand are present.

Bakers Haulover has been dredged historically multiple times to 10 feet plus 2 feet overdepth.

The last dredging event was in 2014. The materials to be excavated consist of shoaling that has occurred since the channel was last dredged. Any insitu rock, if encountered, is not required to be dredged. Gravel- and cobble-sized rock may be encountered in the overdepth from previous dredging.

3 DEFINITIONS

Definitions not explicitly indicated in the sections below are typical industry standard definitions from their respective ASTMs.

4.3 BORING LOG NOTES

All Borings were sampled using an Alpine style, pneumatic vertical hammer, vibracore drilling apparatus having a continuous 10-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.

4.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings is not available for this project.

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. Most of the materials within the project template presented on the boring logs 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 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.

STATEMENT OF TECHNICAL REVIEW AND CERTIFICATION

The Water Resources Engineering Branch has completed the water stage report for the preparation of plans and specifications for the Intracoastal Water Maintenance Dredging 10-Ft Project Vicinity of Bakers Haulover Inlet. Notice is hereby given that technical review, that is appropriate to the level of risk and complexity inherent in the project, has been conducted as defined in the Quality Control Plan. During the technical quality review, compliance with established policy principles and procedures, utilizing justified and valid assumptions, was verified. This included the review of: methods, procedures, and material using in analyses; the appropriateness of data used and level obtained; and reasonableness of the result, including whether the product meets the customer’s needs consistent with law and existing Corps policy.

The quality review was conducted by appropriate team members, with all comments resulting from the review having been resolved. Products developed through an A-E Contractor have been verified to be in compliance with policies and procedures set forth for quality control, quality assurance and independent technical review (ITR).

MEMORANDUM FOR: Chief, Design Branch

SUBJECT: Request for Water Stage Report, Intracoastal Waterway Maintenance Dredging 10- Ft Project Vicinity of Bakers Haulover Inlet, Dade County, Florida

1. As requested by CESAJ-EN-DW email dated 20 June 2017, a Water Stages Report for preparation of Plans and Specifications for the subject project is provided:

2. The following water stage, wave, wind, and weather data are provided for inclusion into the subject Plans and Specifications. The following water level datums are provided for information only and are not to be utilized in conjunction with any contract related hydrographic surveying.

3. A technical review has been performed on the following data and this memo, signed by Chief, Water Resources Engineering Branch, signifies EN-W Branch Quality Control Certification.

a) Water Stages. Water levels in the project area are mainly affected by semi-diurnal tidal fluctuations in the Atlantic Ocean. The project area is also subject to storm surges from hurricanes and tropical storms from June through November. Surges from extratropical storms may affect the area during any time of the year.

Elevations of tidal datums in the vicinity of the project area are provided in the following tables.

All datum elevations in these tables are referred to mean lower low water (MLLW). The datums in the first table are based on field measurements from a tide station located inside of Haulover Inlet and the second table is based on the tide station located at Haulover Pier. The National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS) established these tide stations. The tidal station data for both stations is based on the 1983-2001 tidal epoch.

Additional information on this and other nearby tide stations is available at this NOAA website:

http://tidesandcurrents.noaa.gov/map/index.shtml?type=Datums&region=Florida
