Going underground: waterproofing on Boston's CA/T project
The Central Artery/Tunnel Project (CA/T) in Boston (USA) is said to be the largest, most complex urban infrastructure project in U.S. history. Officials also claim that its USD 10.8 billion price tag exceeds what it would have cost to construct the Panama Canal today. The 'Big Dig' will replace the aging Interstate 93, a perpetually clogged, elevated highway that slices through downtown. In place of this 'Central Artery', a wider underground expressway will be constructed. At the same time, the Massachusetts Turnpike (I-90) will be extended to Logan International Airport. In the end, 161 lane miles will be constructed in a 7.5-mile area. Almost half of CA/T's 161 lane miles are being constructed in tunnels. Construction is currently at peak levels, with approximately USD 3 million of work being completed each day. The project is slated for completion in 2004. In the article, details of the CA/T project are outlined, especially with respect to the measures being undertaken for tunnel element waterproofing installation, including an extensive use of geotextiles. The project comprises the latest equipment and methods for slurry wall construction, excavation support systems, soft ground improvement and geotechnical instrumentation.
