Description:
The construction of a new Courtyard Marriott was proposed for the southeast quadrant at the intersection of Florida (US-61) and Third Streets in Baton Rouge, LA. The $20 million project, highlighted by an 8-story, 147- room hotel, was to be built on concrete spread footings, and slabs on grade, designed to bear on compacted subgrade soils or properly compacted fill.
Based on the results of the geotechnical investigation, excessive settlement was predicted unless ground improvement was provided.
Ground Conditions:
Solution:
To mitigate settlement of the new building, Menard proposed the use of Vibro Stone Columns (VSCs) for support of interior and exterior spread and strip footings. By utilizing 30-in diameter VSCs, total settlement was limited to less than an inch, with a maximum differential settlement between adjacent footings less than 1/2 in.
The VSCs allowed for the construction of footings on improved subgrades. The improved ground provided adequate bearing capacity exceeding the maximum design bearing pressures. A total of 32 helical piers were also installed to resist tensile loads in select footings.
The project met the client's requirements for safety, quality and schedule.
