AD7323.The horizontal coordinates were established by GPS observations

HHD Rehabilitation Project, Reach 1 Cutoff wall Gap Closure, AD7323.and adjusted by the National Geodetic Survey in June 2012.

AD7323.NAD 83(2011) refers to NAD 83 coordinates where the reference

AD7323.frame has been affixed to the stable North American tectonic plate. See

AD7323.NA2011 for more information.

AD7323

AD7323.The horizontal coordinates are valid at the epoch date displayed above

AD7323.which is a decimal equivalence of Year/Month/Day.

AD7323

AD7323.The orthometric height was determined by differential leveling and

AD7323.adjusted by the NATIONAL GEODETIC SURVEY

AD7323.in September 2001.

AD7323.The X, Y, and Z were computed from the position and the ellipsoidal ht.

AD7323

AD7323.The Laplace correction was computed from DEFLEC12B derived deflections.

AD7323

AD7323.The ellipsoidal height was determined by GPS observations

AD7323.and is referenced to NAD 83.

AD7323

AD7323.The dynamic height is computed by dividing the NAVD 88

AD7323.geopotential number by the normal gravity value computed on the

AD7323.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45

AD7323.degrees latitude (g = 980.6199 gals.).

Geotechnical Data Report

1.1 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 1.5.6 and 1.5.7, 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 PROJECT BACKGROUND

Herbert Hoover Dike (HHD) is an earthen embankment that completely encompasses Lake Okeechobee, located in south central Florida. To reduce seepage pathways, restoration of the embankment is being achieved by constructing a seepage cutoff wall into its foundation and replacing the aged culvert structure.

Gaps exist in the Reach 1 cutoff wall at Structures 308, 352, 351, PS-2 and at the Torry Island Bridge. Cutoff wall will be placed in the gaps by tying in to existing cutoff wall and the existing concrete structures.
