Careful attention to appearance has led to <br />numerous engineering design awards. Recent awards include the Fort Lauderdale-Hollywood International Airport Interchange where <br />BHA designed an innovative pier cap. The composite pier cap was the first in the U.S. built using <br />segmental balanced cantilever construction methods, and the project received the national Engineering <br />Excellence Honor Award for American Consulting Engineering Companies (ACEC) as well as the <br />statewide 2004 Grand Award for Engineering Excellence for Florida Institute of Consulting Engineers <br />(FICE). <br /> <br /> <br />2.2 Bridge Development Report <br /> <br />Pf3oE3sI-ri.an E3ric::lg~ <br />over <br />BHA has also designed numerous Dressel's Dairy Canal <br />pedestrian, pedestrian/vehicular bridges <br />where aesthetics has been a pnmary <br />consideration due to the existing ~Il',~...

The report will be prepared to resolve major issues in <br />the overall design and to set the basic parameters for the final design (e.g. bridge type, span arrangements, bridge length, etc.). The <br />following is a proposed outline for the Bridge Report: <br /> <br />1. Executive Summary <br />Brief Description of recommended structural alternate and cost <br />comparison against other alternates considered. <br />2. Existing Conditions <br />Existing features that influence the bridge design, such as, <br />geotechnical conditions, utilities, intersection, R/W, proximity of the <br />buildings and parking to access vibration and settlement/cracks, etc. <br />3. Proposed Alignment <br />Note controlling factors of alignment such as, horizontal and vertical <br />clearances. <br />4. Design Criteria <br />a. Roadway: ADT, Design Speed and Typical Cross Section. <br />b. Bridge: AASHTO, ADA requirements and FDOT Specifications, Live Load, Design Method, Vertical Clearance, etc. <br />c. Bridge Design and Construction over waterway: <br />· U. S. Coast Guard vertical and horizontal clearances if applicable. <br />· Vertical clearance requirements for coastal crossings ( 12 feet above the MHW). <br />· Use of concrete admixtures to enhance durability. <br />· Develop special coatings to provide extra protection in harsh environments if a steel superstructure is chosen. <br />d. Environmental/Permitting <br />Environmental Classification, Easement Required, Permits required, etc. <br /> <br /> <br />5. Alternates Considered <br />a. Superstructure <br />b. Substructure <br />c. Span vs. Cost Graphs <br />6. Analysis and Recommendation <br />Discussion of pertinent issues that control selection including MOT, Cost, Aesthetics, Utilities, Maintenance, constructibility <br />etc. <br />7. Typical Section and Layout of the Proposed Alternate <br />Provide as a minimum Plan and Elevation and Typical Bridge Section (11 "x1 T' drawings). <br />8.
