AMNJ <br /> Intersection of CR 512 at Willow Street: <br /> The traffic signal design will incorporate a mast arm pole design layout in accordance with FDOT mast <br /> arm standards and County's preferred signal configuration for the intersection of CR 512 at Willow Street. <br /> The design will feature LED signal heads, video detection, and overhead street name signs in accordance <br /> with FDOT approved materials. <br /> Intersections of CR 512 and Broadway Street and CR 512 at Cypress Street: <br /> Based on information provided by the County it is assumed that the existing signal poles and span wire <br /> system will require replacement, including replacement of the flashing beacon signal heads and wiring. <br /> Relocation of existing ITS pull boxes and connect proposed signal at Willow Street to ITS system.: <br /> Based on existing pull box locations provided by the County the Consultant will show re-located pull box <br /> locations along CR 512 on the construction drawings and connection of the proposed new traffic signal at <br /> Willow Street to the ITS system. It is assumed there is sufficient slack in the existing pull box for the <br /> relocation. <br /> 4. Structural Review: <br /> Intersection of CR 512 at Willow Street: <br /> The Consultant will review the Project Geotechnical Investigation Report (provided by the County) of the <br /> proposed mast arm locations. The report will be based on the Traffic Signal Concept Plan provided to the <br /> County by the Consultant. The report shall provide geotechnical boring information for all four mast arm <br /> pole locations at the intersection of CR 512 and Willow Street. <br /> Based on review of the Project Geotechnical report, the Consultant will provide a structural evaluation of <br /> the geotechnical findings to determine if FDOT standard signal poles and foundations can be used. If the <br /> finding are outside the standard guidelines then a more extensive structural design for the poles and <br /> foundations will be necessary(not included within this scope of work and fee proposal). <br /> TASK 3A: STRAIN POLE DESIGN <br /> 1. Strain Pole Design: <br /> Intersections of CR 512 and Broadway Street and CR 512 at Cypress Street: <br /> The Consultant will review the Project Geotechnical Investigation Report (provided by the County) of the <br /> proposed signal pole locations. The report will be based on the Traffic Signal Concept Plan provided to <br /> the County by the Consultant. The report shall provide geotechnical boring information for all signal pole <br /> locations at the Broadway Street and Cypress Street intersections. <br /> The Consultant will provide the structural analysis in order to design the two strain poles at each <br /> intersection. This analysis will include designing the poles and foundations and identifying the <br /> appropriate poles at each location. <br /> 2. Subsurface Utility Excavation (SUE): <br /> Atkins will retain the services of a qualified professional to provide SUE at the four (4) proposed signal <br /> pole locations. A maximum of 20 test holes will be performed to clear the foundation locations of utilities. <br /> The proposed foundation locations will be provided to the SUE contractor by ATKINS based on the Traffic <br /> Signal Concept Plan approved by the County. Based on information obtained from the test hole excavation, <br /> the SUE contractor will provide a utility location plan sheet documenting the apparent utility type and <br /> observed location, depth and size uncovered in this investigation. This information will be used in the <br /> design phase to minimize or avoid utility relocations. The utility location plan sheet will be forwarded to <br /> the County for their information regarding any utilities that require relocation. <br /> March 23,2016 <br /> Page 4 of 10 <br />
