Charter was contracted by the US Army Corps of Engineers (USACE) New England District to perform construction of the Muddy River Flood Risk Management and Environmental Restoration Phase 1 Project located in the Fenway section of Boston, Massachusetts.
The project consists of the installation of two 24-foot wide by 10-foot high pre-cast concrete arch culverts supported by drilled shafts for 3’ diameter and approximately 50 -foot long caissons under existing roadways, the construction of concrete headwalls and wing walls also supported by caissons, installation of granite veneer and capstones, excavation to construct open channel sections of river, and landscaping of new and existing channel sections. The scope requires dewatering sections of the Muddy River, earth support systems, removal of existing culverts, utility modifications, construction of new and temporary roadways, installation and modification of traffic signals and controllers, and construction of a weir structure upstream of the project area. Because of the busy urban setting, there are significant traffic management requirements to minimize impacts on the surrounding infrastructure.
