| Description |
Shirley forces, as part
of the TKC Joint Venture, played numerous key
roles in the construction of the foundations for
the future bridge. Shirley pile driving crews
supervised and placed the main land piles consisting
of 72” and smaller diameter steel tubes up to
and over 175 feet in length. These large piles
provided the support for massive footings to support
the ultimate precast substructure system. In conjunction
with this operation, Shirley Crews provided piles
driving and shoring support for land excavation,
as well as constructing cofferdams in the Potomac
River for the marine foundations. Utilizing both
vibratory and hydraulic pile hammers ( capability
of up to and over 365,000 ft. lbs. energy) and
handled by both track and a Ringer Based Crane
due to the massive weights and sizes of individual
members the project was one of the significant
“heavy” projects for the region. |
