HIGHWAY DESIGN: URBAN STREETS PONCE DE LEON BOULEVARD IMPROVEMENTS Coral Gables, Florida This project involved the streetscape reconstruction of Ponce de Leon Boulevard through the City of Coral Gables Design District. In order to fund the project, the City of Coral Gables established a Local Improvement District for all properties fronting Ponce de Leon Boulevard, and project costs were assessed to these properties on a frontage basis. The improvements consisted of sidewalk reconstruction, drainage systems, curbing, parking reconfiguration to create landscaped islands, decorative tree grates with foxtail palms along both sides of the street, irrigation, street resurfacing and provision for future conversion to underground electrical service for street lights. Our firm was intimately involved from the conceptual planning and public workshops, through design, permitting and bidding, and we performed the construction administration, public information and final project cost apportionment.   HIGHWAY DESIGN: RURAL HIGHWAYS MINOR HIGHWAY – 3R DESIGN SERVICES C3TS has completed design services for numerous Resurfacing, Restoration, and Rehabilitation (3R) projects throughout Florida, on both urban to rural roadways. Each 3R project poses unique challenges including geometric deficiencies, right-of-way restrictions, ADA compliance, drainage improvements, utility conflicts, varying pavement sections, etc. C3TS has developed various innovative concepts that include reduced plan production drawings, cross slope correction schemes, variable milling concepts, early coordination with project stakeholders, and close coordination with utility agencies to ensure the project goals and objectives are satisfied. Our 3R projects have ranged from multi-lane urban arterials to rural undivided 2-lane facilities with and without paved shoulders. We have provided solutions to various corridors including railroad crossing replacements, bridge railing retrofits, sidewalk placement within an existing urban area, geogrid reinforced pavement sections, etc. Our design teams understand the value and need to maintain our roadway system. Our solutions are aimed at extending the service life of the road while addressing safety and operational deficiencies.

HIGHWAY DESIGN: MAJOR ARTERIALS
SR-50 (W. COLONIAL DRIVE) MAJOR HIGHWAY DESIGN SERVICES
Lake & Orange Counties, Florida

FDOT District V selected C3TS to provide Final Design Plans for the widening of W. Colonial Drive (SR-50) from a 4-lane rural arterial to a 6-lane divided urban arterial from west of Hancock Road in Clermont, FL (Lake County) to east of the Turnpike Interchange (MP 272) in the Town of Oakland (Orange County). The added capacity is intended to service the rapid ongoing development through most of western Lake County and southern Orange County. Numerous commercial developments have emerged subsequent to commencement of the project, including Super Target, Publix, Walgreens, McDonalds, and Clermont Dodge to name a few. The new SR-50 section will also include 6 travel lanes, a divided median, bike lanes, and sidewalks. The project, despite numerous changes and complex challenges has remained on schedule and is one of the first along the corridor to obtain funding for construction, which is set to begin in 2007.

SR-7 / US-441 MAJOR HIGHWAY DESIGN SERVICES
Palm Beach County, Florida

The expansion of western Palm Beach County over the last twenty years has created the need to increase the capacity of the county’s north-south arterials. As development moved further west, the need to widen SR-7 / US-441 from a two lane rural arterial to a multi-lane suburban arterial became a necessity. Upon obtaining Location Design Concept Acceptance for the expansion of SR-7 from FHWA, District IV of the Florida Department of Transportation selected the firm of C3TS to develop expansion plans for the segment of SR-7 which lies between Boynton Beach Blvd. and Lake Worth Road. The reconstruction of this section consisted of widening the road to a six-lane divided facility with a construction cost of $23.0 million dollars. C3TS’ design engineers faced unique challenges in the development of this project. Dealing with complex drainage issues and multiple drainage districts complicated the permitting of the improvements. Extensive coordination with the adjacent residential and farming communities due to impacts brought about by the construction and required right-of-way acquisition necessitated additional public involvement efforts and one-on-one coordination meetings. C3TS was asked to participate in the Partnering Process as part of the Post Design Services. The Partnering team was composed of the Department’s contractor, the CEI firm and C3TS as the designers. Coordination with the permitting agencies and impacts from new developments, right-of-way agreements and new utility installations were just a few of the complex issues dealt with during construction. Through the Partnering Process, these challenges were resolved and/or incorporated into the construction process. The team’s efforts demonstrated the benefits of Partnering by delivering this corridor to the public ahead of schedule.

SR-50 (BLOXAM AVENUE TO HANCOCK ROAD)
Lake County, Florida

C3TS provided engineering services to expand SR-50 from West of Bloxam Avenue to West of Hancock Road. The project includes the reconstruction of the SR-50 / SR-25 interchange within the city limits of Clermont and improvements to several local off-system roads including Grand Highway, Hook Street, Highland, etc, to facilitate access and mobility to neighboring businesses and communities. The existing diamond interchange configuration requires two additional signals at the ramp terminals resulting in the need for four traffic signals within a half-mile segment of SR-50. To improve this congestion, C3TS developed a new alternative that includes a partial cloverleaf configuration that eliminated two signals and improved mobility along SR-50. The design of the new partial cloverleaf interchange includes several significant challenges due to the limited right of way available. Extensive Public Involvement and coordination with Lake County and City of Clermont was required to develop an intergraded concept amenable to all stakeholders. C3TS worked with FDOT to develop an innovative approach to project delivery that included breaking up the project into two segments (Section at Interchange and Section to the East). This approach permitted the FDOT the flexibility to Let the interchange with either the on-going SR-25 six-laning project, or the segment to the east, should funding become available for one first. To catch up to the SR-25 design job already at the 90% phase, C3TS proposed an Initial/Final plans review process along with an advanced right of way phase to ensure the interim design of the interchange was not required, thereby reducing extensive throwaway work and saving millions of dollars.

HIGHWAY DESIGN: LIMITED ACCESS FACILITIES

SR-482 (SANDLAKE ROAD) / SR-435 (KIRKMAN ROAD) INTERCHANGE WIDENING
Orlando, Florida

C3TS provided highway and bridge design services to the FDOT on this very important limited access facility. The interchange is located at the entrance to the Lockheed Martin facility in Orlando. The improvements to the interchange included the widening of five (5) multi-span AASHTO beam bridges and the widening and resurfacing of the mainline portion of SR-482 within the limits of the interchange. The challenges overcome by the C3TS Team included the development of a complex traffic control scheme to minimize impact to the traveling public. This multi-phased traffic control scheme allowed expansion of the bridges to each side and included temporary detours for placement of bridge girders.

SR-874 KENDALL DRIVE NORTHBOUND ON-RAMP TO
SR-874 / SR-878
Complex Highway Design – Miami Dade County, Florida

The Miami-Dade Expressway Authority (MDX) selected C3TS to provide design services for the construction of a new SR-874 northbound on-ramp from Kendall Drive. The 1.25-mile new ramp consists of approximately 2,000 feet of curved twin steel box girders supported by eccentric post-tensioned concrete piers. The project also includes the final geometrics of the future SR-874 mainline including the SR-878 System Interchange to ensure constructability of future mainline capacity improvements given the proximity of the new on-ramp. This project includes a noise study along the corridor and noise abatement measures, including a noise wall along the east side of the ramp, north of the C2 canal (Snapper Creek) that will be required. In addition, the ramp will be converted to Sun-Pass only requiring the use of Electronic Toll Collection. Some additional structural services provided by C3TS under this contract include 30% plans and BDR for the westbound SR-878 flyover over mainline SR-874, and analysis for the special sign support structure to be adopted by MDX as its standard sign support system.

I-95 (SR-9A) SB WIDENING FROM NW 125th STREET TO OPA-LOCKA BOULEVARD
Miami Dade County, Florida

The FDOT District VI selected C3TS to provide Capacity Improvements to southbound I-95 (SR-9A) from NW 125th Street to Opa-locka Boulevard. The purpose of the project was to balance the number of lanes through this section by providing an additional general-purpose lane and the relocation of the existing exclusive auxiliary lane. The project involved the widening of the existing roadway section that consists of concrete pavement and is supported intermittently by MSE walls. Modified pre-stressed beams were used to maintain existing vertical clearances with NW 131st Street and NW 135th Street. The widening of this section of I-95 involved three bridge structures. Given the tight nature of the right-of-way in this area, various retaining wall systems were required. Also, considering the proximity of the proposed walls to the existing systems, special designs were required to attach the new wall straps to the existing walls. At the southwest approach to the NW 131st Street bridge, a special tie-back anchored H-pile wall with a concrete fascia was required. The soil anchors were driven through the existing MSE soil mass. This wall required increased height and reinforcement since the existing MSE wall strap density did not meet the proposed requirements. In addition, the existing drainage system, which consists of exfiltration trenches and swales, was modified to meet the additional needs. Coordination to avoid conflicts with the existing ITS facilities was carried out and design plans for relocating this facility prior to construction were completed. Right-of-way coordination was completed early for a temporary construction easement to allow for the widening of the NW 131st Street bridge which spans the current parking area for St. James Catholic Church and School.

TURNPIKE SAFETY
Turnpike Enterprise

C3TS has been selected to provide fast-track contract documents for several projects including the Median Barrier Project for the HEFT in Miami-Dade County from MP 0.0 to MP 17.0 and the Canal Protection Project for all of Miami-Dade County. In an attempt to reduce the accidents resulting from the median crossovers, the Turnpike created both of these projects and counted on C3TS to deliver. This project included provisions for several barrier systems to be constructed along the Turnpike median to prevent crossovers that were contributing to the number of fatalities. The Turnpike asked C3TS to prepare Contract Documents for a Test Pilot Project for three distinct cable barrier systems. These systems were all new to the State of Florida and C3TS coordinated extensively with the manufacturers, Central office, maintenance, construction, etc. to include the necessary details and technical special provisions. In addition to the cable barrier, single- and double-face guardrail were used. Special details and coordination was required for the placement of emergency turnarounds / crossovers with FHP.
