	San Francisco Ferry Building Seismic Restoration. The retrofit of this historic structure started in early 1997. The building is occupied and thus, much of the construction work has been during the night hours and on Saturdays. Several areas were damaged by the Loma Prieta earthquake. Renovation required the preservation of historical structural parts, which were integrated with new construction. Vintage steel was analyzed for weldability to new steel. Some cast iron structures were located but no welding was performed onto cast iron. The major strengthening was to add heavily reinforced shotcrete shear walls to the structure.
	San Francisco International Airport Concourse H/ART. This BART Extension/Concourse H/ART Station was constructed as part of the Master Plan for the New International Terminal to bring together the new BART extension with a major aerial rapid transportation (ART) system for the San Francisco International Airport. The BART train arrives on the 5th level and passengers can transfer to the SFIA aerial transit system on the 7th level. The station is a four level 264,000 sq. ft. reinforced concrete structure supported on precast concrete piles. The seventh level canopy is designed with prescribed TK&Y node connections where SFIA has requested ISI to inspect with automated ultrasonics in lieu of radiography. .
	Fire Station #1 and #3, Vallejo, CA The project was the special inspection and materials testing for improvements to two existing fire stations. The scope of work included concrete mix design review, assistance with interpretation of procedures and advise on the provisions of the contract documents pertaining to cast-in-place concrete work and CMU walls.
	Pier 30-32 Investigation, Port of San Francisco ISI was hired to perform the structural investigation of 4,000 existing concrete piles and pile caps under the Pier 30-32 structure. Services included visual inspection and testing, coring of damaged piles, underwater visual inspection (performed by Underwater Resources), pachometer testing, and Schmidt Hammer testing. ISI inspectors identified and documented over 1,000 damaged piles. All work was performed from a 12' skiff during low tide periods over an 8 week fast-track schedule.
