7 GROVE AT GRAND BAY Miami FL Terra Grove Communities LLC BIG/NBWW Geotechnical The former Grand Bay Hotel site was replaced by two 21-story luxury residential towers and a three-level podium in Coconut Grove. The varying depth to the towers' bearing layers required that augercast pile foundations vary from intermediate to deeper depths. Langan worked closely with the project design team and the general contractor to understand loading requirements and site constraints caused by former precast pile foundations from the previous development as well as potential impacts to neighboring properties from the project construction activities. Langan's coordinated geotechnical studies were performed prior to and during demolition of the former building which resulted in timely foundation designs for the two towers and amenities podium.

8 1000 MUSEUM Miami FL 1000 Biscayne Tower LLC Zaha Hadid Architects Geotechnical Environmental 1000 Museum will be the first high-rise building in the Western Hemisphere designed by Pritzker Award winner Zaha Hadid. This ultra-luxury residential building will rise 62-stories and ultimately stand out amongst its neighbors at 710- feet-tall. The project fronts historic U.S. Highway 1 in the heart of Downtown Miami. Former uses of the site included a gas station and a pawn shop. Langan provided geotechnical and environmental services in support of the project.

9 PORTMIAMI TUNNEL Miami FL Florida Department of Transportation City of Miami Florida Miami Access Tunnel Concessionaire Partner: Bouygues Civil Works Florida Geotechnical Lead Designer: Jacobs Engineering Group This project is the first large-diameter tunnel constructed in Florida's challenging soft sedimentary geology using a tunnel boring machine (TBM). The purpose of the PortMiami Tunnel is to relieve traffic congestion in downtown Miami by diverting car truck and bus traffic from nearby highways directly to the Port of Miami through twin 42-foot diameter tubes extending below the main ship channel. Langan evaluated the subsurface data to develop the geotechnical engineering parameters required for design of the bored tunnel and the TBM. Langan also observed and monitored early-phase testing consisting of foundation load testing and Cutter Soil Mixing for the U-wall and cut-and-cover portions of the project.
