Bridge Deck and Median Barrier Reconstruction, Milepost 160.6 to 162.5

Professional Engineering Services are required for the supervision of construction of Contract No. P100.511, Bridge Deck and Median Reconstruction, Mile Post 160.6 to 162.5 Contract P100.511, Bridge Deck and Median Reconstruction, Milepost 160.6 to 162.5 involves the partial demolition and reconstruction of Bridge Nos.161.5S, 161.6S, 161.7N, 161.8S and 161.9N on the northbound and southbound roadways of the Garden State Parkway. The work will be accomplished in stages while maintaining the flow of traffic by utilizing multiple lane shifts and precast concrete construction barrier. Bridge Nos 160.6S and 160.7N will be reconstructed in weekend High Intensity Construction Cycles. Work at these structures consists of demolition and replacement of bridge deck slabs with precast concrete steel composite panels, precast HPC panels, cast in place HPC construction include the installation and removal of MPT measures, milling, substructure concrete spall repairs, deck joint replacement, bearing replacement, diaphragm replacement, cleaning and repainting structural steel, replacement of underbridge lighting, waterproof membrane installation, paving, temporary bridge supports and pavement resurfacing. Precast panels will be set in place by mobile crane during off peak or night time hours and will require closure pours using specialized grout material. The concrete median barrier will be replaced and roadway milled and paved between Milepost 160.6 and 162.5. All concrete bridge decks will be micro-milled to meet current Authority ride quality standards. The bridge decks of Bridge Nos. 162.1S, 162.2N and 162.4S will be repaired by milling, spall repairs and paved prior to new joints installed at the abutments prior to final paving and stripping
