Site work and paving for a civil project in Pittsburgh, Pennsylvania. Completed plans call for site work for a bridge / tunnel; for paving for a bridge / tunnel; road / highway; and road / highway.

The cost estimate is: $500,000 - $999,999 This work provides for the superstructure replacement, approach roadway work, and temporary bridge work for the existing single-span non-composite prestressed adjacent box beam structure. The structure carries Booker Street over Pucketa Creek and connects Plum Borough (Allegheny County) to the west and Upper Burrell Township (Westmoreland County) to the east. The existing bridge has a center-to-center bearing length of 43'-6" (45'-0" total length), a skew of 90 0' 0" at both abutments, measures 28'-3" out-to-out (22'-6 1/2" curb-to-curb) and carries two lanes of bi-directional traffic. A 3" bituminous wearing surface is present on top of the box beams. The existing bridge railing consists of concrete curbs with 3'-0" high steel railings mounted to the curbs and fascia beams. A 4'-0" wide raised sidewalk is present along on the right side. The existing superstructure consists of seven 48" x 21 " prestressed concrete adjacent box beams. The substructure consists of two reinforced concrete gravity abutments. The simple span replacement structure consists ofseven new 48" x 17" prestressed concrete adjacent box beams with a new 5 A" minimum thickness reinforced concrete composite deck and concrete barriers. The proposed cross section will have a 26'-6" curb to curb and a 28'-6" out-to-out consisting of two 9'-0" lanes, a 2'-0" left shoulder with a 1 ft wide by 2'- 8" high vertical face concrete barrier, and a 6'-6" right shoulder with a 1 ft wide by 3'-6" high vertical face concrete barrier. The existing beam seats will be demolished and rebuilt to maintain the low chord values of the existing bridge. The existing neoprene bearing pads will be replaced with new elastomeric bearing pads meeting cun-ent design standards. The reinforced concrete substructure will remain in place except for portions of the bridge seats and wingwall tops, which will be reconstructed to accommodate the new beams and barriers. The wingwalls consisting of reinforced concrete crib-wails adjacent to the abutment stems will remain in place. The widened right shoulder will not feature a raised sidewalk but will utilize pedestrian-friendly features including special striping adjacent to the vehicle lane and the same TL-5 barrier typically used on raised sidewalks. The proposed bridge profile sets within a crest vertical curve and is aligned horizontally on tangent. For the replacement structure, work includes bridge seat and partial wingwall reconstruction at both abutments, placement of a new prestressed composite adjacent box beam superstructure (including deck and barriers), proper disposal of portions of the existing abutments, and proper disposal ofthe existing prestressed adjacent box beam superstructure. For the temporary bridge structure, work consists of procurement, design, construction and demolition of a modular open-panel temporary bridge. For the replacement structure, this work also includes full depth bituminous pavement reconstruction and associated approach roadway work, including but not limited to placement of updated guide rail, maintenance and protection of traffic during construction, new signing and pavement markings, and erosion and sediment pollution control measures within the project limits as indicated on the drawings. These work items are also applicable to the temporary bridge and temporary bridge approach roadways where applicable. Traffic control measures consisting of lane shifts for Greensburg Road (SR 0366) from Sta. 5+83 to 13+70, will be required to perform approach roadway tie-in work along the shoulder of Greensburg Road during the superstructure replacement project. A modular open-panel temporary bridge will be constructed just upstream of Pucketa Creek Bridge No. 5, which will maintain access to SR 0366 for residents of the neighborhood located east of the bridge. *The value for this project is based on a financial range.
