Massachusetts Department Of Transportation Highway Division Proposal No. 609200-106704 DOCUMENT A00801 SPECIAL PROVISIONS BERKLEY, LAKEVILLE AND FREETOWN 4 Railroad Bridge Replacements (Steel) along the South Coast Rail Line over the Cotley and Cedar Swamp Rivers and Fall Brook Labor participation goals for this project shall be 15.3% for minorities and 6.9% for women for each job category. The goals are applicable to both contractor’s and subcontractor’s on-site construction workforce. Refer to document 00820 for details. SCOPE OF WORK Location 1 – Cotley River Bridges North and South (Bridge No’s B-08-004 and B-08-005) The work at this location includes replacing Bridge Number B-08-004 and Bridge Number B-08- 005 on the New Bedford Main Line over Cotley River North and Cotley River South respectively, in Berkley, Massachusetts. The proposed improvements include the demolition and reconstruction of the bridge carrying the New Bedford Main Line over the Cotley River as shown in the Contract Documents, including earthwork, full depth railroad track construction, steel sheeting or block walls for wetland avoidance, and drainage improvements to accommodate the bridge replacement. The new bridges will consist of a single span ballasted steel deck plate girder superstructure with precast concrete stub abutments on driven steel H-piles to support the (future two-track) New Bedford Main Line. The new bridges are designed to provide 1'-9" (minimum) of hydraulic freeboard at the design Q100 flood event. The New Bedford Main Line is currently operated and maintained by the Mass Coastal Railroad and used to support local freight rail service. The plans are detailed showing a two-phase construction process. Phase 1 constructs the offline portion of the bridge while the existing bridge maintains active service. Phase 2 constructs the online portion of the bridge under the specified track shutdown. Alternatively, the proposed work in Phase 1 may be completed simultaneously with phase 2 during the track shutdown. With regards to the track construction, the Cotley River trackwork will follow a similar phasing as the bridge construction phases. Due to constraints imposed by the operating railroad, Mass Coastal, the track at the Cotley River Bridges must remain in service throughout the construction process. Although only a single track will be in service upon completion of this project, approximately 4,350 linear-feet each of Tracks 1 and 2 will need to be constructed to maintain continuous operations through the project area. Phase 1 of the bridge construction will also include Phase 1 of track construction, construction of Track 1 to its final profile and alignment. When Track 1 and Phase 1 of the bridge construction is completed service will be shifted from the existing track to the newly constructed Track 1. Track 2 will be constructed simultaneously with Phase 2 of the bridges construction. Upon completion of Track 2 construction, train service will be shifted back over to the Track 2 alignment and Track 1 will be dead ended on both ends. A00801 - 1 Massachusetts Department Of Transportation Highway Division Proposal No. 609200-106704 SCOPE OF WORK (Continued) Location 2 – Cedar Swamp River Bridge (Bridge No. L-01-018) The work at this location includes replacing Bridge Number L-01-018 on the New Bedford Main Line track over Cedar Swamp River Bridge in Lakeville, Massachusetts. The proposed improvements include the demolition and reconstruction of the bridge carrying the New Bedford Main Line over the Cedar Swamp River as shown in the Contract Documents, including earthwork, full depth railroad track construction, steel sheeting wall installation for wetland avoidance and global stability related to existing subgrade conditions, and drainage improvements to accommodate bridge replacement. The new bridge will consist of a single span ballasted steel deck plate girder superstructure with precast concrete stub abutments on drilled micro-piles to support the single-track New Bedford Main Line. The new bridge is designed to provide 1’-10” (minimum) of hydraulic freeboard at the design Q100 flood event. The New Bedford Main Line is currently operated and maintained by the Mass Coastal Railroad and used to support local freight rail service. Accelerated bridge construction techniques shall be utilized to limit track outages. Work also includes the installation of approximately 300 feet of steel sheeting wall to provide embankment support and with 3” diameter weep holes for drainage. There is also approximately 110 feet of steel sheeting on either side of the track approaching the bridge (220 feet total) for global stability support. The track work at Cedar Swamp River Bridge consists of approximately 3,500 linear-feet of new track construction, a small percentage of which is replacement of track, ties, OTM, and ballast, while the majority is full depth construction inclusive of 8” of subballast, 12” of ballast, and all the related track materials. Location 3 – Fall Brook Bridge (Bridge No. F-09-028) The work at this location includes replacing Bridge Number F-09-028 on the New Bedford Main Line track over Cedar Swamp River Bridge in Freetown, Massachusetts. The proposed improvements include the demolition and reconstruction of the bridge carrying the New Bedford Main Line over the Fall Brook as shown in the Contract Documents, including earthwork, full depth railroad track reconstruction, steel sheeting walls for slope stability as well as global stability related to existing subgrade conditions, drainage improvements to accommodate bridge replacement, and installation of a proposed culvert. The new bridge will consist of a single span ballasted steel deck plate girder superstructure with drilled micro-piles behind the existing stone masonry abutments to support the single-track New Bedford Main Line. The new bridge is designed to provide 5 feet of hydraulic freeboard at the design Q100 flood event. The New Bedford Main Line is currently operated and maintained by the Mass Coastal Railroad and used to support local freight rail service. Accelerated bridge construction techniques shall be utilized to limit track outages. Work also includes the removal of a 3’x3’ box culvert and installation of a 7’x7’ cross- track concrete box culvert. The track work at Fall Brook Bridge consists of approximately 1,100 linear-feet of new track construction, a small percentage of which is replacement of track, ties, OTM, and ballast, while the majority is full depth construction inclusive of 8” of subballast, 12” of ballast, and all the related track materials.
