The trestle will maintain the same footprint as the new bridge, but it will be constructed above the bridge's <br />profile. Removable crane mats will allow caps to be built and beams set from the same trestle. Because the <br />weight of the exterior beams is so great, a 200 TN crane must be used on the trestle. <br />Concurrently with the structures work over water, the roadway work will begin on the opposite side of the <br />bridge. The exfiltration trench along 172nd Street will be constructed in the wet so that no dewatering will <br />be required. Work along this road will take place adjacent to live vehicular and pedestrian traffic, requiring <br />the use of flaggers and special attention to eliminate drop off and clear zone hazards after each shift. <br />Roadway and MSE wall construction will take place after drainage. MSE work is common for us, but the <br />tight access on the south side will require special material handling plans to construct. We have constructed <br />several roads in Miami with the similar geogrid typical sections. <br />Furthermore, we have developed excellent relationships with South Florida subcontractors, which will <br />perform the flatwork, lighting, fencing, paint and asphalt work. We treat subcontracted work as our own <br />and will maintain a supervisor over each operation. <br />As seen on the construction schedule below, the anticipated award date is on 5/18/15 with the anticipated <br />NTP on 6/22/15. With the given completion time of 390 days, we have scheduled the work to be completed <br />by April 14, 2016 in 297 days. All the work shown on the schedule will be completed with one structures <br />crew and one roadway crew. The critical schedule items, which will be subcontracted, are the soil mixing <br />and drilled shaft work. <br />OBid 4/10 <br />0 Award 5/18 <br />0 NTP 6/22 <br />Owner Substantial Completion 7/16 0 <br />— Permits <br />F: Mobilization <br />f : Set MOT :— :172nd St. MOT <br />+ Mangroves Clearing <br />Soil Mix : : : 2 Week Cure Time <br />Erosion Control <br />F� Temporary Trestle F—: Remove Trestle <br />H Test Shaft <br />• Drilled Shafts <br />:--: Demo Seawall :: Rip Rap <br />:—: South Abutment <br />: Drainage <br />F i Substructure Concrete <br />0 Kiewit Completion 4/14 <br />H Remove MOT <br />Roadway & MSE Walls <br />F iSet Beams <br />Form and Place Decks <br />:—: North Abutment <br />F� Barrier Wall and Flatwork <br />:--i Approach Slabs <br />F� Barrier Wall <br />F--+ Lighting <br />Class V Paint <br />-- :Fencing and Signs <br />F—i Flatwork <br />:— Asphalt and Striping <br />MKiewitConstruction of the North Bay Road Pedestrian Emergency Bridge I No. 14 -09 -01 <br />
