Professional Service Industries (Geotechnical Engineering) Newport Pier Restaurant and Fishing Pier, Sunny Isles Beach, FL PSI is currently providing geotechnical construction material testing and inspection on this project. The project will include the construction of a restaurant structure and a fishing pier in Sunny Isles, Florida.

The canal banks had undergone significant slope failures and an I t r l emergency re~ponse was re~uired t~ evaluate the ~~~-;":;;:. ~11",:"'~~~1i\~' ;Il!'~. _~ cause of the failures and solutions to fix the problem. e-'.. ~. ...4-4 '. . ~ "~1 .1; In addition to reviewing the subsurface conditions, our ~.

Slope stability models were developed using the program PC-Stabl and RSS for both steady state and rapid draw-down conditions. We provided several remedial options such as the modifying the slope, the use of gabion walls, riprap and sheet piles for this project along with a study on the cost implications of each alternative 5197 Structure Replacement, U.S. 1 in Proximity to Manatee Bay, Miami Dade County, FL The project site is located near the mouth of Canal C-l11 and is less than 1,000 feet east of U.S. 1 and approximately 3 miles from the shore of Manatee Bay in the Southeastern part of Miami-Dade County, Florida (Homestead Field Station service area). The SFWMD is planning to replace the existing S-197 water control structure from corrugated metal pipe (CMP) culverts to reinforced concrete box structures. I The 5-197 structure maintains optimum upstream water level in Canal C-l11 and prevents saline . intrusion during high tides. Most of the time, 5-197 . diverts discharge from the S-18C overland to the panhandle of the Everglades National Park and releases water during major floods as established by the structure's operational plan. Performance of field work included a full-time manatee observation and turbidity monitoring. In land, the geotechnical field investigation revealed surficial fill material comprising Iimerock, fine sand and silt. In water, a soft compressible silt stratum was disclosed. Keeping in mind, the potential settlement to be induced by the proposed structure, PSI provided cost-effective foundation alternatives. They also provided recommendations for a cofferdam and tremie seal to facilitate construction. ,CH UfO No,ll'04-04!Jesig/l ami I'ermilti/lg Services ofllle ll1tracoastllll'arks &ASSOCIAICS
