LINDE FUSRAP SITE REMEDIATION, UTILITY TUNNEL REPLACEMENT, ANDINDUSTRY OPERATIONS: A CASE STUDY OF CHALLENGES MET IN WESTERNNEW YORK

摘要

Building 14 was a radiologically impacted Manhattan Engineer District-era (MED) structure atrnthe Linde Formerly Utilized Site Remedial Action Program (FUSRAP) remediation site inrnTonawanda, New York that required dismantlement in 2004. Remedial action at the Linde Siternrequired simultaneous radioactive contamination cleanup, active industrial facility infrastructurernrelocation and uninterrupted facility operations. The challenge was to design and construct arnreplacement subsurface utility tunnel, relocate numerous active utilities, and remove allrnradioactive contamination within the new tunnel’s footprint within 16 months to allow Buildingrn14 dismantlement to start on time. The U.S. Army Corps of Engineers – Buffalo Districtrn(USACE) and Shaw Environmental, Inc. (Shaw) worked in close cooperation with the facilityrnowner to design and execute the work. Meeting the challenge involved design and constructionrnof a new structure, a large open excavation between closely spaced steel and masonry buildings,rnand of several utility systems including high-pressure steam, high voltage electric, and fiber opticrncommunications concurrent with removal of several thousand tons of uranium-238 (U-238),rnradium-226 (Ra-226), and thorium-230 (Th-230) impacted material. Design started in Februaryrn2003 and construction was completed in June 2004 to meet the Building 14 dismantlement startrndate.
