Project consisted of demolishing a 38-slip marina built in 1953 and building a 50-slip marina in the same footprint. There were 156 - 7'' OD pipe piles and 16 - 12-3/4'' OD pipe piles that supported 5000 SF of synthetic wood decking on the lower floor and 6000 SF of composite steel floor deck on the upper floor. Because of unforeseen conditions caused by blasted rock from the original construction of the marina, approximately 260 linear feet of 3 ft by 3 ft grade beams had to be constructed while Lake Austin was lowered to support 60 of the 7'' OD pipe piles. Also, a reinforced gabion was built to support 35th Street.
Project consisted of driving 228 - 8-5/8'' OD pipe piles that ranged from 39 to 61 feet due to an excavated pit for the theatre's trap. A 20 foot wall of 25 foot long, 6 gauge sheet piles supported by 12-3/4'' OD pipe piles and tied back to 8-5/8'' OD pipe deadmen was constructed to allow for temporary support of a heritage oak adjacent to excavated pit.
Project consisted of removing sediments from Michael's Cove connected to Lake Austin along Westlake Drive. Original depth of cove varied from 6 to 24 inches and was dredged to 3 to 6 feet in depth. Over an 8 week schedule, approximately 360 truck loads of material was hauled offsite. Aquatic plants were planted to rehabilitate the wetlands after construction.
