I-595 Shared-Use Drainage

The I-595 corridor in Broward County, Florida, is being reconstructed to accommodate three reversible tolled express lanes in the median and additional auxiliary lanes. RS&H serves as the Owner’s Representative for the Florida Department of Transportation (FDOT) in a public-private partnership agreement to design and construct the $1.2 billion project and was tasked with identifying a cost-effective solution for managing the stormwater. 

Limited right-of-way available along the 10.5-mile corridor posed significant permitting and drainage challenges. To minimize right-of-way acquisition and avoid impacts to nearby residents and businesses, RS&H designed shared-use drainage facilities by partnering with three privately owned golf courses adjacent to the corridor: Lago Mar, Pine Island Ridge, and Arrowhead. 

RS&H provided quality verification and oversight on the final design and construction of the Lago Mar and Pine Island Ridge Golf Courses and served as the final design consultant for the Arrowhead Golf Course. The drainage facilities within the Arrowhead Golf Course consist of a series of wet detention ponds, which are interconnected with 48-inch pipes. The increased pond areas and modifications to the interconnecting pipes and control structures maintain the peak stages within the golf course ponds and the peak discharges from the ponds into the receiving water bodies at approximately the existing levels.

By incorporating social, economic, and sustainable design considerations, the I-595 shared-use drainage project offered a “soft” engineering solution that effectively balanced transportation needs with the surrounding environment and community. The project ultimately saved FDOT over $60 million in potential right-of-way acquisition costs, offered a solution for implementing capacity improvements in highly populated and dense urban areas, and balanced the state’s transportation needs with social and environmental considerations.

Ulmerton Road Widening

During design for the widening of Ulmerton Road in Pinellas County, Florida, RS&H identified an innovative solution that saved the Florida Department of Transportation over $13 million in right-of-way costs, while simultaneously accommodating two adjacent projects for the county.

In addition to widening 1.5 miles of the corridor while adding bicycle lanes and five-foot sidewalks, the original design called for extending the road north to avoid impacts to a large and unsafe drainage ditch along the south side of the corridor. Shifting the roadway north would require substantial right-of-way acquisition. However, since the ditch was within the existing right-of-way, RS&H recommended creating a box culvert to convey the stormwater in lieu of the ditch, thus allowing the corridor to shift south instead. This alternative reduced costs from just over $17 million to approximately $3.48 million and ultimately improved safety within the corridor.

Early in the project, the team also learned that the county was planning to extend the multi-use Pinellas Trail by constructing a $3.5 million pedestrian bridge over Ulmerton Road. The county also planned improvements to the intersecting Cross Bayou Canal, which is a designated blueway. To accommodate both projects, RS&H designed a three-span concrete bridge for Ulmerton Road’s crossing of the canal, which also included a pedestrian ramp that merged the trail extension with the newly widened roadway. This alternative added to the cost of the widening project, but ultimately saved over $1.5 million from what the county would have spent on a completely separate pedestrian bridge.

I-10/I-610 Interchange Reconstruction

RS&H prepared the geometric design, as well as construction plans, specifications, and estimates (PS&E) for one of the most heavily congested freeway interchanges in the United States: the four-level I-10 Katy Freeway interchange with I-610 Loop Road in Houston, Texas. This interchange is projected to accommodate over 270,000 vehicles a day by 2023 and was one of ten sections along I-10 reconstructed by the Texas Department of Transportation to improve travel conditions in northwest Harris County.

The project included eight system-to-system directional ramps, four system-to-service ramps, and two high-occupancy vehicle (HOV) flyover ramps to the area’s Northwest Transit Center. Also included were improvements to the area street network, as well as interstate grade separations with surface streets and the Union Pacific Railroad.

Since our geometric design of the interchange affected two adjacent design sections, it was critical to complete the renovations within six months in order to maintain the overall corridor schedule. RS&H completed final plans only 27 months after notice to proceed.

Daytona Beach International Airport

As general consultant for Volusia County, Florida, we provided architectural, engineering, planning, and environmental services as determined by a FAA Part 139 Certification inspection that cited portions of the airfield lighting system and airfield marking system were found to need upgrades. Our team designed improvements, which complied with FAA standards, and performed construction services, including numerous partial airfield closures. We also prepared an Environmental Assessment, developed the preliminary engineering report, and designed the Runway 25R Category I ILS system. Among the other services, we designed and provided construction administration services for the Taxiway N reconstruction. RS&H provided design services, which indicated a new pavement section and modified portions of the centerline profile.

Spokane International Airport

RS&H was selected by Spokane International Airport to develop an Apron Rehabilitation program in order to replace old and deteriorated Portland Cement Concrete (PCC) panels in the airport’s existing terminal apron area. The project included an initial pavement evaluation of the existing apron that identified the extent of the panel replacement. Based upon the results of the study, we recommended a full apron replacement. Our team developed plans and specifications to replace the existing PCC ramp, add drainage infrastructure for future glycol collection, regrade ramp to meet NEPA 415, and upgrade the ramp and feeder taxiway connectors to Group IV standards. Elements of the project include geometry, pavement design, drainage/detention pond relocation, airfield lighting, phasing, scheduling, cost estimates, plans, specification, and extensive coordination with airlines and tenants at SIA.

Antilles Elementary School Design-Build RFP

RS&H provided the multidiscipline architecture and engineering to develop a design-build request for proposal (RFP) for a new elementary school. We performed an original planning charrette. In 2011, we modified the design to meet 21st Century Education curriculum. When the design was revised to meet the new criteria, our team spent time working with the Domestic Dependents Elementary and Secondary Schools (DDESS) Area Service Center leadership to define goals. We also conducted presentations to the educators at Antilles to help introduce the 21st Century Education curriculum and define how a new curriculum would affect the new school design. Through indepth client interviews, the design team was able to develop a responsive and effective design-build RFP, which met 21st Century Education concepts while staying within budget and land resources.  

The facility will be LEED Silver certified. Some innovative design requirements include a small demonstration-size green roof, photovoltaic farm, and wind farm. These provide students with outdoor learning opportunities, which are especially significant given the climate of Puerto Rico. Also, traffic circulation was a challenge due to the school site’s residential area. The final design will improve local traffic circulation and enhance safety for the students walking from adjacent housing areas.  

District Superintendent Office

RS&H provided multidiscipline architecture and engineering design of a new administration facility for the District Superintendent at Fort Bragg. The facility includes offices, conference rooms, and other support/administration areas, as well as a multimedia training room for continuing education use. The facility also includes historic artifacts and photo documentation of the history of Department of Defense Educational Activity (DoDEA) Schools on Fort Bragg.  

The design and placement of the building is intended to maximize the view and filter daylight on the wooded side of the facility. The building is designed to meet LEED Silver Certification, as well as meet or exceed all executive orders, including a 40 percent energy reduction as established by ASHRAE 90.1. The building includes a number of sustainable and energy reduction features, including photovoltaic parking lot lamps, photovoltaic roof panels, natural day lighting, clerestory windows, building automation systems, and recycled paving and walks.

Repurposing Building M-207

Under an IDIQ contract, RS&H completed a condition assessment, conducted a planning charrette for repurposing the facility, and prepared designs for the rehabilitation of Building M-207. The two-story, 25,146-square-foot building was originally constructed as a Marine barracks in 1941 and through the rehabilitation, will be repurposed to provide an office building for administration staff. RS&H’s services included full architectural, multidiscipline engineering, interior design, and construction administration services. This project will be designed and constructed to meet the number of LEED credits and all energy-using systems will be either Energy Star or Federal Energy Management Program (FEMP) recommended efficiency.

Joint Indoor Training Tank

RS&H was the Designer of Record for the design-build construction project of a new 25-meter indoor joint water survival training tank, which can accommodate 50 students. The permanent, single-story facility includes all support elements required by the US Navy to use the pool to train military personnel in swimming and water survival, as well to support all military physical fitness programs.

The building is a combination of concrete masonry block walls and structural steel framing, pile foundations with reinforced grade beams, and a slope standing seam metal roof. RS&H designed the facility according to LEED Silver Certification standards, utilizing sustainable principles throughout development, design, and construction in accordance with Executive Order and Energy Policy Act 2000.
