ROGER A. ARCHABAL, P.E. RELEVANT EXPERIENCE DEEP FOUNDATIONS Mr. Archabal has served as project engineer and project manager for a wide variety of deep foundation systems, including all types of driven piles and drilled cast -in -place piers; and augered cast -in -place (augercast piles). Several of his representative projects are presented below: Oceania Island - North Miami Beach, FL - The project consisted of two 28 -story tower structures and associated parking garage structures on a man-made island in the Intracoastal Waterway. The island was created by placement of varied fill primarily consisting of sand and rock fragments, but also including pockets of organic materials and construction debris. Fourteen and 16 -inch diameter augercast piles, 45 to 55 feet long and socketed into competent limestone, were ultimately selected for support of the Parking Garage and Tower Structures, respectively. Special interest was given to the installation of uncased augercast piles through the varied fill. Pile "pull -out" tests and load tests proved that installation of uncased augercast piles was feasible for production. Over 1000 production piles were installed under close supervision without complications. Louisiana Light & Electric (LL &E) Tower - New Orleans, Louisiana - Project consisted of a geotechnical exploration and load test evaluation for a 37 -story high -rise building. Considering the soft, compressible upper deltaic soils, it was necessaryto support the structure on 350 foot long, 30 inch diameter steel pipe piles embedded in a thick, very dense sand stratum to achieve a 350 ton designload carrying capacity. American Airlines Arena - Miami, FL - The project consisted of construction of a 20,000 seat sports arena, built over and old port area and dredged fill deposits. Consultation included providing foundation recommendations with regard to high capacity auger -cast piles, dewatering recommendations and ground floor slab elevation requirements. Mr. Archabal served as Project Engineer. ' Key Biscayne Resorts and Residences, Key Biscayne, FL - The project consisted of the development of two high rise Condominium Tower structures, a high rise resort Hotel Tower structure, associated Parking Garage structures and amenity structures, adjacent to the Atlantic Ocean. The geotechnical exploration, ' conditions and geotechnical evaluation resulted in augercast piles foundations being the preferred foundation alternative. Sixteen -inch diameter, 150 -ton design capacity piles, installed to depths of 50 to 55 feet, were used to support the Tower structures. Pile load tests and production pile supervision were also ' performed. The Parking Garage and smaller structures were supported on shallow foundations using a bearing capacity of 5 kips/ftz. Miami International Airport - Miami, Florida - Mid -rise Parking Garage No.7 and 5 to 7 -story Concourse ' D /E/F Wrap Structures projects. Based on structural loading, site constraints and site history, augercast pile foundations were recommended for support of these structures. Recommended pile diameters ranged from 16 to 18 inches for design load capacities of 130 to 200 tons. Pile embedment lengths were designed I to minimize settlements to less than one inch. At both sites installation concerns which were addressed and consisted of potentially deleterious upper fill materials, as well as petroleum contamination. Regional Distribution Warehouse - New Orleans, Louisiana - The project consisted of the construction of a one million square foot distribution center located on a site that had received 10 to 15 feet of hydraulically dredged fill materials decades before. The facility was to utilize a high -tech, sensitive rail ' system for merchandise handling which could only tolerate a maximum of 1/10 of an inch of deflection over 10 feet. Based on the geotechnical study and pile load testing program, a 65 foot long, composite timber - concrete (spliced) pile was chosen as the most suitable and economical rile type. ' Perdue Feed Mill - Bridgeville, Delaware - The project consisted of the construction of a new Feed Mill Facility containing various heavy structures including a 125 foot tall Silo and a 160 foot tall slipform-
