SPECIAL PROVISIONS

SOMERVILLE

Federal Aid Project No. HIP(NGB)-003S(987)X

Bridge Replacement, S-17-016, Webster Avenue over MBTA/BMRR

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

All work under this Contract shall be done in conformance with the 2026 Standard Specifications for Highways and Bridges, the Supplemental Specifications contained in this book, the Construction Standard Details in effect as of July 2026, the 1990 Standard Drawings for Signs and Supports, the 2015 Overhead Signal Structure and Foundation Standard Drawings, the 11th Edition of the Manual on Uniform Traffic Control Devices (MUTCD) and the January 2026 Massachusetts Amendments to the MUTCD, the 1968 Standard Drawings for Traffic Signals and Highway Lighting, the latest edition of The American Standard for Nursery Stock, the Plans and these Special Provisions.

The work done under this Contract consists of furnishing all necessary labor, materials, equipment and services to replace Bridge No. S-17-016, which carries Webster Avenue over the MBTA/CSX in the City of Somerville, Massachusetts. The bridge was built in 1911 and is comprised of steel floor girders, floor beams, and stringers that support a timber and reinforced concrete deck. The proposed replacement bridge will be a single-span steel plate girder structure with reinforced concrete deck.

The existing superstructure and portions of the existing substructure are to be removed. Proposed abutments, founded on micropiles, will be constructed in front and on top of the existing abutments. The proposed superstructure will be comprised of steel plate girders, a reinforced concrete deck, paved roadway, and CP-MTL3 bridge barriers. The proposed bridge alignment will be slightly modified to move the intersection of Newton Street with Webster Ave off the bridge and into approaches. This allows for a slight narrowing of the existing bridge footprint. The vertical clearance of the proposed bridge is slightly raised to match the low chord of the adjacent Prospect Street Bridge.

The structure will be replaced in a single stage due to the difficulty of staging the demolition of the existing floor girder bridge superstructure. A vehicular and pedestrian detour will be implemented to facilitate construction. The proposed curb-to-curb width over the bridge of 24’-0” allows for two 10’-6” travel lanes, a 2’-0” shoulder on the west side and a 1’-0” shoulder on the east side. An 8-6” sidewalk is located on the west side and an 18’-6” sidewalk with separated 10’- 0” bike lane on the east side. CP-MTL3 bridge rails are also proposed and will connect with existing sidewalks at all four corners of the bridge. The proposed bridge span is 77’-10” between centerline of bearings with a total project length of 556 feet.

SCOPE OF WORK (Continued)

Additional work to be completed includes a splayed wingwall at the northwest corner, temporary Verizon and City of Somerville Fire Department utility relocations, and permanent Eversource Gas and Electric, Verizon and City of Somerville Fire, and City of Somerville Water utility relocations. There is an Eversource electric substation at the northeast corner of the bridge and the existing substructure shall be used to retain the existing grades in this area. The adjacent MWRA utility bridge is not proposed to be affected by this project and the Contractor shall take care not to damage this structure. Various utilities are located within the project limits that must be relocated to facilitate construction. The Contractor shall, as part of this work, coordinate with all utility owners before and during construction. The work will also include coordination with MBTA/Keolis to relocate overhead MBTA PTC wires into proposed conduits below grade.

The work includes bridge construction, roadway reconstruction, drainage modifications, pavement markings, landscaping, utility relocations, and other incidental items necessary to complete the required work. All work shall be performed in accordance with all environmental permits included in this contract document.

On Federally-aid projects the Buy America (23.CFR § 635.410) and Build America, Buy America Act. requires the following,

(1) all iron and steel used in the project are produced in the United States--this means all manufacturing processes, from the initial melting stage through the application of coatings, must occur in the United States. Foreign steel and iron can be used if the cost of the materials does not exceed 0.1% of the total Contract cost or $2,500, whichever is greater.

The action of applying a coating to a covered material (i.e., steel and iron) is deemed a manufacturing process subject to Buy America. Coating includes epoxy coating, galvanizing, painting and any other coating that protects or enhances the value of a material subject to requirements of Build America, Buy America. Steel used for temporary support of excavation, including H piles, soldier piles, and sheeting when the steel is required to be left in place is subject to requirements of Build America, Buy America. Temporary steel, shall remain in place when it falls within the influence zone of the soil supporting any structure or railroad tracks.

(2) all manufactured products used in the project are produced in the United States—this means the manufactured product was manufactured in the United States and

(3) all construction materials are manufactured in the United States—this means that all manufacturing processes for the construction material occurred in the United States.

“Construction materials” includes an article, material, or supply—other than an item of primarily iron or steel; a manufactured product; cement and cementitious materials;

aggregates such as stone, sand, or gravel; or aggregate binding agents or additives—that is or consists primarily of:

• non-ferrous metals,

• plastic and polymer-based products (including polyvinylchloride, composite building materials, and polymers used in fiber optic cables),

• glass (including optic glass),

• lumber; or

• drywall.

The Buy America preference only applies to articles, materials, and supplies that are consumed in, incorporated into, or affixed to an infrastructure project. As such, it does not apply to tools, equipment, and supplies, such as temporary scaffolding, brought to the construction site and removed at or before the completion of the infrastructure project. Nor does a Buy America preference apply to equipment and furnishings, such as movable chairs, desks, and portable computer equipment, that are used at or within the finished infrastructure project but are not an integral part of the structure or permanently affixed to the infrastructure project.

All articles, materials, and supplies should be classified as an iron or steel product, a manufactured product, or another product as specified by law or in 2 CFR part 184 (such other products specified by law or in 2 CFR part 184 include “excluded materials” and “construction materials”); an article, material, or supply must not be considered to fall into multiple categories.
