Tab 4. Schedule & Methodology Our Methodology & Approach to Completing the Work As an experienced bridge and roadway constructor, we understand the work involved with completing the North Bay Road Pedestrian Emergency Bridge. One of the main elements is installing 42 -in. drilled shafts. Then, the substructure is placed on bents founded on the drilled shafts. The bridge's superstructure will consist of a cast -in -place reinforced concrete deck supported by continuous Florida 1 -36 prestressed concrete beams. In addition, a barrier wall with handrail and a Class 5 finish will be installed. Another primary element is the bridge deck. In order to accomplish the deck's tricky pour, the bidwell will have to be setup on a skew to match the bents vs. perpendicular to the bridge deck. This will ensure that the beams will all deflect at the same time. Additionally, the bidwell's west side will have to stay loose so that it can adjust to fluctuating span dimensions. Another project aspect is the clear and grub work. On the south side of the roadway, work can start from the east to the west on NE 172nd Street. During this operation, all the organic material will be removed under utility installations. The geosynthetic fabrics (BX1200 and BX 1100) will be used to stabilize the area underneath the roadway. This method was used successfully in a high traffic area on the outside shoulder of US 441 during the Golden Glades project. After clear and grub on the north is completed, the soil mixing subcontractor will mobilize the north side. Due to the weight of the embankment in the MSE walls on the organic layers, there will be short -term and long -term settlement. We concur with the geotechnical report that the best option to mitigate this issue is soil mixing. We have used this exact application of soil mixing at the Port Everglades project. The advantages of soil mixing include low vibrations, mostly clean and quiet work, the use of readily available materials such as cement, and it generates nearly no spoils for disposal. In addition to these technical project aspects, we understand that this project will require effective coordination and communication with local businesses and residents to minimize potential impacts and keep them informed. We work with the City to foster positive perception of the project by the project and other stakeholders. We will also remain diligent about protecting the area's natural resources and way of life by minimizing any potential impacts to the environment. With experience such as building a bridge in the Florida Everglades, we understand the concerns of working in environmental sensitive areas around the state and how to comply with all the extensive requirements. Our Organization of the Project The timely and efficient project delivery is the end goal of all project teams. We want to look back on the job and be proud of what was accomplished and the manner in which it was built. This fact has driven our project management organization to adopt a Partner - Driven Approach. This foundation of our approach will be built on solid partnering and teamwork principles established on previous projects, putting the project goals first and maintaining open and honest communication from start to finish.
