6400 Bluewater Timeshare Resort, Hilton Head Island SC. Fine Tuned Structures is the Structural Engineer of Record for this private development project. The building is approximately 88,000 sq. ft. 6 story tall located in Bluewater Resort and Marina in Hilton Head Island, South Carolina. This is the third building in the same development designed by Fine Tuned Structures. The Architect for the project is General Design, Inc. of Branson, Missouri. The contractor is Fraser Construction from Bluffton in South Carolina. The main structural system is reinforced concrete frame with two-way reinforced concrete post-tensioned slabs. Lateral support is provided by specially reinforced concrete shear walls. Resisting lateral loads and keeping torsion into control was very challenging on this project due to the length of the building and the lack of any shear walls along the waterfront façade. The architectural vision for this side of the building was for large windows to allow owners a full view towards the beautiful intercostal waterway. The entire first level is on-ground parking under the building which restricted the use of large shear walls and columns. The building is supported on auger cast displacement piles. All structural plans are generated with Revit Structure. With very aggressive schedule the project was completed in July 2016 approximately 14 months since construction began.
