W. L. French completes mass excavation at 399 Binney, upcoming lab and office building in Kendall Square

W. L. French Excavating Corporation has completed the mass and footing excavations for 399 Binney Street, an upcoming 172,500-square-foot lab and office building located in Kendall Square, one of the United States’ strongest life sciences real estate markets. W. L. French has hauled and disposed of over 60,000 tons of soil, and is currently preparing and installing basement slab subbase materials. As part of W. L. French’s contract to install site utilities at 399 Binney, work has begun to connect water services to the project site. W. L. French will install water infiltration, drainage and sanitary sewer systems throughout the site in Spring 2018. 399 Binney’s excavation is supported by an internally braced support of excavation system, which was installed between May and July 2017.

Completion of 399 Binney is expected by the end of 2018. The building will be built to LEED Gold efficiency certifiable standards and will also include a 1,500-square-foot ground-floor retail space. 399 Binney is part of the existing nine-building One Kendall Square office and retail campus, which 399 Binney developer Alexandria Real Estate Equities acquired in November 2016 from DivcoWest for $725 million, or $1,124 per square foot, one of 2016’s most significant real estate sales. Space at 399 Binney is now available for lease, with demand reportedly strong; overall, the Cambridge lab real estate market has a microscopic vacancy rate below 1% per Lincoln Property Company's latest Cambridge Office & Lab Market Report.
