Bridge Replacement Over the Williams River

in West Stockbridge, MA

Under MassDOT’s Accelerated Bridge Program, JHM replaced a structurally deficient 1927 bridge that carried two lanes of traffic over the Williams River.  JHM demolished the old 50 foot, single span concrete T-beam superstructure consisting of a concrete deck and bituminous concrete wearing surface. Maxymillian’s 240 ton crane picked the large, heavy demolition pieces and loaded them onto trucks for off-site removal. JHM replaced the existing bridge with a new 73 foot long, 35 feet wide superstructure consisting of NEXT Beams with a concrete deck. The bridge replacement was performed in 2 stages.  An earth support system of soldier beam, lagging and tiebacks was installed down the center of the bridge to maintain traffic flow on one side of the road, while working on the other half.  The full scope included installing a new bridge rail, safety signing, wetland creation, and pavement markings.

Concrete Retaining Wall Replacement Adjacent to Rt. 9 at Bridge #C-21-023 over the Westfield Brook in Cummington, MA

JHM replaced a failed major retaining wall located along Route 9.  Prior to commencing wall demolition and construction, JHM designed and installed a temporary earth support system above the failed wall for slope protection and constructed access to the channel elevation. JHM then installed water control/diversion from the work area, removed sections of the failed wall, constructed sections of new concrete walls, removed debris from Hurricane Irene, installed rip rap, backfilled, and restored the existing slope.

Sawyer Library Demolition and New Quad at Williams College in Williamstown, MA

This was a $12 million, multi-phased renovation that created an innovative, new green space/academic Quad in the heart of the Williams College campus.  The extensive, fast-tracked project scope was completed in two phases.

In Phase 1, JHM demolished the Sawyer Library and installed temporary sidewalks and turf that would be replaced in Phase 2 with the new Quad landscaping. Before collapsing the library into its footprint, a custom 4 story beam/netting shield was erected to protect the occupied school buildings less than 25’ away. Over 7,000 CY of demo material was crushed on-site and combined with 5,000 CY of local borrow to backfill the cellar hole. JHM also constructed the new Stetson Plaza, the new North Parking Lot, and a new Chapin Hall Drive South. In Phase 2, 8 JHM crews and 16 subs were adeptly coordinated 8-10 hours/day to demo, hardscape and landscape the entire 3.4 acre space in only 12 weeks.

GRS-IBS Bridge Replacement

over Housatonic RR in Sheffield, MA

JHM was awarded the ENR 2015 Best Small Project for this bridge reconstruction project, the first Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS) of it's kind designed and constructed in Massachusetts. JHM provided labor, materials, and equipment required for the replacement of Bridge No. S-10-023, which carries Route 7A/Ashley Falls Road over the active Housatonic Railroad. JHM installed a single span, 105' steel; multi-girder structure on a 30-degree skew with GRS abutments founded on reinforced soil foundations. The abutments work together with the integrated approach and superstructure, resulting in a GRS-IBS bridge. This method provided minimal disruption to the community and train traffic below. Using GRS-IBS on this multi-million dollar project saved 49% compared to the original design that featured conventional construction.
