Solicitation Number: W912WJ-20-Q-0104 July 2020

A. General Description of the Work to be Performed

The general description below is given to indicate the approximate scope of this project only. It does not limit the work required under the project drawings and specifications.

The Old South Street Bridge at Westville Lake in Sturbridge, Massachusetts was constructed in 1956. The bridge is a two lane bridge (26'-0" wide roadway) and carries Old South Street over the Quinebaug River. The bridge is a simple span, composite steel stringer bridge with a span length of 85'-6 1/8" and a total bridge length of 89'-6". The bridge is affixed with 2'-8" high steel handrails on top of 2'-3" wide by 0'-8" high curbs on each side.

The purpose of this project is to repair/ remove deteriorated concrete, replace broken concrete curb, and install four Object Markers at the Old South Street Bridge located at Westville Lake Dam in Sturbridge, Massachusetts.

The scope of work for this project will focus on concrete repair work which will include the rehabilitation of the concrete bridge deck and curb and as shown on the plans. There is broken concrete curb along the North and South Approach slabs that will be replaced with granite curb. The repair work to be performed by the Contractor requires the removal of unsound and deteriorated concrete on 100% of the deck as shown on the plans. The locations and areas of the concrete repairs shown on the drawings are approximate. Some selective light demolition will be required around the existing expansion joint steel plates to ensure full continuous repair under the expansion plate as shown in the drawings. There is one fixed joint and one expansion joint on the bridge. The extent of the curb repair along the bridge deck will be localized to one area as shown on the plans. The final areas of concrete repairs and depths on the deck shall be based on sounding the concrete and visual inspections performed by the Contractor and the Contracting Officer Representative, also known as (COR). The depth of removal on the deck will be 3” across the entire deck. In areas where the deterioration is below this depth, the removal depth shall be up to 5”. For example, if sound concrete is encountered at 3”, no more removal is required. Alternatively, if sound concrete is not encountered at a depth of 3”, chipping shall continue until sound concrete is encountered or to a maximum depth of 5”, whichever is encountered first. The entire deck shall have a minimum of 3” of concrete removed. During concrete removal, if any areas appear to be unsound below 5”, the Contractor shall notify the COR for guidance.

Surface preparation and concrete removal equipment may be of the following types:

(1) Pneumatic and Power Driven Chipping Hammers: In no event shall any pneumatic or power hammer weighing in excess of twenty-five (25) pounds be used for the removal of concrete.

Pneumatic power hammers heavier than the nominal fifteen (15) pound class shall not be used for removing concrete from below any reinforcing bar.

(2) Hydro-Blasting: The contractor shall be able to contain water and concrete debris during the operation.

Water and concrete debris shall not enter the waterway.

Completion of scope of work may require fall protection. Means of access shall be approved by the Contracting Officer's Representative prior to beginning of work.

Following completion of the work, the area shall be restored by the Contractor to its condition prior to the start of construction. This shall include regrading and seeding disturbed grass embankment areas beyond where granite curb was placed.
