BY DESIGNS A F E T YTYLI engineers strive to present designs

that reflect the communities they serve

while meeting critical transportation and safety

needs. The new Pedestrian Overpass at University

Metrorail Station that crosses the U.S. 1/Mariposa Court

intersection in Coral Gables, Florida, is no exception.

The new Pedestrian Overpass at University Metrorail Station keeps users off the busy highway.

TYLI provided complete design services for the pedestrian bridge, which opened to the public on August 8, 2017. At 125 feet long, the translucent steel pedestrian bridge now provides an important link between the adjacent residential and business neighborhoods of Coral Gables and the University of Miami (UM) campus and the heavily used University Metrorail Station.

TYLI’s scope of work on the Pedestrian Overpass at University Metrorail Station project included design services for structural, mechanical, electrical, and civil engineering, architecture, surveying, right-of-way issues, soils investigation, utility identification and relocation, lighting, and maintenance of traffic. The firm also oversaw coordination with Miami-Dade Transit (MDT) and other affected entities, including the City of Coral

Gables, Miami Dade Public Works, the Miami-Dade Building Department, the Transportation Aesthetics Review Committee, the Florida Department of Transportation, the University of Miami, and other local permitting agencies.

For the TYLI team, safety during construction, as well as the ultimate safety of the final overcrossing, were key concerns throughout the design, coordination, and implementation of the project. Sadly, over the past 20 years before any overpass existed, the U.S. 1/Mariposa Court intersection had been the site of a number of pedestrian fatalities or serious injuries as students tried to cross the busy arterial highway. That kept the community’s gaze firmly fixed on this high-profile overpass project.

Safety during construction, as well as the ultimate safety of the final overcrossing, were key concerns throughout the design, coordination, and implementation of the project.

The initial conceptual study phase of the project began in 2006, and included bridge design, public involvement activities, construction documents, technical specifications, and preparation of the engineer’s estimate of probable construction cost. TYLI held architectural concept coordination meetings with the lead agency, MDT, and the City of Coral Gables to develop and receive approval on the details of the bridge supports and special design features integrated into the structure.

The final concept for the Pedestrian Overpass at University Metrorail Station, which was designed by TYLI’s Architecture & Visualization group, was conceived in two parts. First, the elevator towers are solid, stately masses that are clad in local fossilized limestone. Reflective of the historic houses in the adjacent Coral Gables neighborhoods, the substantial towers anchor the bridge to its community heritage. Then, the truss jumps off in a futuristic direction.

TYLI’s context-sensitive design took into consideration numerous factors, such as quality of life, livability, sustainability, the cultural environment, architectural styles, natural environments, and the open-space character of the neighborhoods surrounding the overpass. While the resulting structure is simple and efficient – two circulation towers connected by a steel truss – its architectural character is quite unique.

Clad in a series of perforated metal fins that constantly change angles to create a flowing wave form, the truss is emblematic of the more contemporary architecture styles found at UM and throughout greater Miami. The wave feature gives the structure a sense of dynamic movement, making people curious about how the distinct form looks from all angles. This, in turn, accomplishes one of TYLI’s key goals: to allow innovative design to draw people to use the bridge, thereby keeping them safely off and away from the busy highway below. >>>

TYLI Completes Strategic Countywide Master Plan Last year, TYLI’s Atlanta office was selected to provide the Fairfield County - Strategic Community and Economic Development Master Plan (SCEDMP). The countywide master plan, delivered by TYLI earlier this year, has been designed to enable the County to preserve the qualities that make it unique while stimulating economic potential to ensure quality future development patterns.

The TYLI team created the SCEDMP using data analysis and the identification of specific goals and objectives. The document describes a broad vision for the County, implemented through an array of guiding principles that describe policies, programs, and projects, all supported by a comprehensive public engagement process.

The public engagement process validated the master plan by identifying community groups, who then described goals and selected their particular vision for the future. Through an effective implementation strategy, the SCEDMP will affect both social change for the County through an economic development program, and physical change through the adoption of policies and improvements to infrastructure.

The Fairfield County Vision is a set of implementable policies, programs and projects for the three elements of most concern for county residents: Housing, Community Image, and Education. To “Plan and Strategize” is at the heart of implementation, including various methods and tools for implementing goals imbedded in the master planning process. These include Housing – diversity programs and policies; Image – creating a positive “brand” for Fairfield County; and Education – improvements to diversity in education that include a promotional effort for existing

educational achievement, programs, and policies. The vision for the master plan is “Build & Create,” to be achieved through implementation of specific projects related to Infrastructure, Improved Services, Business Development, Heritage Tourism, and Recreation Development. >>>

TYLI Completes Design of MIA Airfield Improvement ProjectIn August 2016, the Miami-Dade Aviation Department (MDAD) selected TYLI to design a $70M airfield improvement project at Miami International Airport (MIA). The project includes taxiway rehabilitation, a new parallel taxiway R, expansion of an aircraft cargo parking ramp, filling of a canal as part of major drainage improvements, construction of a fuel tender truck parking lot, and replacement of a Glide Slope and precision path indicator (PAPI) for aircraft guidance to the runway.

This project was especially challenging on three fronts. First, the design needed to be complete by June 2017 in order to capture sizeable funding from the Federal Aviation Administration (FAA). Second, the project is being constructed in a contaminated site. Finally, at the 100% submittal, MDAD directed TYLI to move the new taxiway 50 feet further away from the runway, resulting an intense effort to produce a new set of plans within one month. Ultimately, the project was bid on time, and the low bid was within 3% of TYLI’s engineer’s estimate.

Moving forward, TYLI has been engaged to provide full construction administration, management, and inspection services for the three-year duration of the project. The firm’s Miami Aviation Group is to be commended for successfully completing a major, client-directed redesign effort within an unreasonably tight timeframe. The total fee once this project is completed will be over $6M. >>>

TYLI Supports Transportation Modeling Study for Virginia DRPTTYLI recently provided travel demand modeling support on an economic benefit analysis for the Virginia Department of Rail and Public Transportation (DRPT). The study, titled “Quantification of Economic Benefit Resulting from Public Investments in Transportation for Virginia Department of Rail and Public Transportation (DRPT),” estimated the impact of transit service changes on transit mode share and highway network travel time reliability, with a focus on Northern Virginia, Richmond/Tri-Cities, Hampton Roads, and Fredericksburg.

Scope of work included a thorough review of the Virginia Department of Transportation (VDOT) and Metropolitan Washington Council of Governments (MWCOG) travel demand model to determine specific transit modes to be included in both base year and future year for service change alternative analysis. Definitions of scenarios were developed based on various transit operations characteristics, study years, and different times of day. Travel demand forecasting models provided by VDOT and MWCOG were used for analysis.

Development of transit service change scenarios: Among the many factors that may affect travelers’ willingness to take transit, such as headway (defined as the time between consecutive services, such as a train that runs every 30 minutes), transit run time (average speed), transit fare, and parking availability near a transit station/stop, TYLI selected headway as the key variable. The percentage change is based on a DRPT funding scheme.

Travel demand model run and output data compilation: Transit headway changes were coded in the four regional models before model run started. Numerous scripts were prepared to automate output data formatting and post-processing. Performance measures included passenger miles (hours) traveled by transit sub-mode, vehicle miles and hours traveled (VMT/VHT) by vehicle type, and transit share.

SHRP2-C11 reliability analysis data preparation: Based on INRIX corridor peak period congestion data, Route 7, I-95, I-395, and I-66 were selected for travel time reliability analysis. Input data, such as free flow speed, number of lanes, capacity, and passenger vehicle/commercial vehicle value of time, were extracted from the model. >>>

Topsham Trails Opens to PublicOn June 1, 2017, TYLI joined a ribbon-cutting ceremony celebrating the completion of the second phase of the Topsham Trails bicycle/pedestrian path system in Topsham, Maine. The project was funded through the Maine Department of Transportation and managed locally by the Town of Topsham Planning Department.

TYLI designed the 10-foot-wide, half-mile trail segment, which connects the town’s Main Street and municipal offices area to a retirement community, medical and Red Cross office buildings, and the Topsham Fairgrounds site. The off-road trail passes through a forested area and along a state-owned right-of-way, providing a safe and attractive alternative to walking or riding on busy local roads.

This segment was the second phase of a trail system that was recommended in a Feasibility Study completed by TYLI in 2004. The completed system will eventually connect Topsham’s trail system to the Androscoggin River Path in the neighboring town of Brunswick, which is a 2.6-mile-long trail currently used by approximately 2000 bicyclists and pedestrians every week, from spring through fall. The path is also part of the East Coast Greenway, a national trail system proposed to extend over 2,100 miles from Key West, Florida, to Calais, Maine. >>>

Substructure construction throughout the project is also ongoing, with all the marine foundations completed. Another milestone was achieved this summer when the first segments of the steel pier caps reached the job site from Spain. The unique W-shape of the steel pier caps is one of the major architectural features of the bridge, and is repeated on all 38 piers throughout the 3.4-kilometer-long structure. As the precast concrete pier legs are being completed, the steel pier caps are being lifted on top of the pier legs and anchored via post-tensioning.

The New Bridge over the Saint Lawrence (NBSL) team is surely having a very busy 2017. The next phase of erection will be the construction of the upper towers, cable-stays, and superstructures of the signature cable-stayed bridge – all of which go hand-in-hand and require meticulous erection engineering supports. The NBSL team is ready for the challenge and looks forward to seeing the signature span take its shape against the backdrop of the Montreal skyline.

New Champlain Bridge Corridor Project ContinuesConstruction is in full swing on the New Champlain Bridge in Montreal, Quebec, Canada. TYLI is the managing partner of the TYLI-IBT-SLI Joint Venture responsible for the design of this major signature structure.

The new bridge reached a major milestone this summer when the upper crossbeam of the Main Span Tower, nicknamed “bow-tie” because of its shape, was lifted into place. The 400-metric-ton bow-tie was casted onsite and lifted into place in one piece, anchored and clamped in place by prestressing rods and tendons. Together with the lower crossbeam, the bow-tie forms the A-frame of the Main Span Tower. Following the bow-tie erection, the upper cast-in-place portion of the tower will continue to rise, allowing the stay-cables to be anchored and supporting the erection of the superstructure segments.

On the superstructure front, construction for the back-span girder is ongoing. The precast deck panels are reinforced with stainless steel rebars that provide protection against the corrosive environment under deicing salt exposure. At the precast shops, a total of eight casting lines were used to produce 38-48 panels per week. To date, close to 40 panels for the north, south, and transit corridors are installed and about 12 stitch pours are being completed onsite.

Marwan Nader Presents Paper on New Champlain BridgeMarwan Nader, Technical Director of TYLI’s Bridge Line of Business, presented a paper that he co-authored with colleagues from Infrastructure Canada, International Bridge Technologies, SNC Lavalin, Inc., and Flatiron Construction Corp. on August 22, 2017, at the 9th annual New York City Bridge Conference. The session, entitled, “Bridge Analysis & Design III,” covered the topic of the design and construction of the New Champlain Bridge in Montreal, Canada.

The Abstract for the paper reads: “The deteriorating condition and associated high maintenance costs of the existing Champlain Bridge (opened to traffic in 1962) prompted the accelerated need to design, build, operate, maintain, and finance the New Champlain Bridge Corridor Project. Part of

the largest transportation infrastructure project currently underway in North America, the 3.4-km New Champlain Bridge comprises a signature cable-stayed bridge, an east approach, and a west approach. Performance and

design criteria for this lifeline structure must meet the design-life requirement of 125 years. The severe winters in Montreal, along with the requirement to maintain navigation channel traffic during construction, present unique challenges to design and erection. The design-build team provided innovative use of precasting, modular segments, and non-traditional erection techniques and sequencing to meet the fast-track project schedule.” >>>

Two Projects Win Project of the Year Awards from ASCE MLAB TYLI received Project of the Year Awards from the American Society of Civil Engineers, Metropolitan Los Angeles Branch, (ASCE MLAB) for two recently completed projects for the City of Santa Monica in California. The California Incline Bridge Replacement was named Outstanding Road and Highway Project of the Year. The Idaho Avenue Pedestrian Overcrossing Replacement was selected as Outstanding Bridge Project of the Year. The ASCE MLAB Awards recognize projects that further advance the field of civil engineering and provide an exemplary display of the ASCE values.

TYLI served as Lead Designer for the California Incline Bridge and associated improvements, including roadway, multiuse bicycle and pedestrian path, drainage, and replacement of a 12-inch water main. TYLI also oversaw traffic and electrical engineering, geotechnical engineering, hazardous material testing, and surveying. The 750-foot-long, cast-in-place concrete post-tensioned slab bridge replaces a series of deteriorating sidehill viaduct structures built in 1930. The new, seismically resilient bridge begins atop the bluff slopes of Pacific Palisades Park and carries vehicular traffic, pedestrians, and bicyclists down to the Pacific Coast Highway at the base of the bluffs near Santa Monica State Beach.

For the Idaho Avenue Pedestrian Overcrossing, TYLI served as Prime Consultant, providing concept alternative analysis, architectural design and visualization, final engineering, and construction support for the overcrossing and improvements to the Idaho Trail. The new landmark pedestrian bridge is a curving structure with a signature V-shaped pier that emerges seamlessly from the historic Idaho Trail and spirals tightly around the vertical clearance envelope of the California Incline roadway. Connecting to a new multiuse pedestrian/bicycle path, the bridge offers panoramic views while providing users with a safer, more efficient path of travel.

“From the onset, the T.Y. Lin International team was dedicated to overcoming challenging site conditions in order to provide the City of Santa Monica and local residents with the most structurally sound, efficient, and visually aesthetic structures possible,” says Mark Ashley, TYLI West Region Director. >>>

Hayford Creek Bridge on Wildwood Road Wins ASCE Award TYLI’s Sacramento office was recently honored with the 2016 Outstanding Structural Project of the Year Award from the American Society of Civil Engineers (ASCE), Sacramento Section, for the new Hayfork Creek Bridge on Wildwood Road in Weaverville, California. TYLI served as Prime Engineer.

The project replaced a deteriorating, single-lane bridge built in 1928 with a 162-foot-long, cast-in-place prestressed slab, supported on pier walls founded on spread footings and seat abutments. The new, 2-lane bridge improves traffic flow and provides the capacity for 100-year flood events. The project also included realignment of the approach roadway, where access at the river crossing and residential driveways had to remain unobstructed at all times.

Preliminary studies included a hydraulic analysis and geotechnical report, including scour analysis and seismic issues. Because the abutments of the old bridge required deep excavations, and the potential existed for cultural resources within the project area, a geoarchaeological study/excavation was also overseen and reviewed by the TYLI team.

Following the preliminary engineering phase, TYLI provided full plans, specifications and estimate (PS&E) for the bridge replacement. The firm also assisted the Trinity County Department of Transportation in successfully securing Federal Highway Bridge Program funds and additional special cost approvals for the project. >>>

D I D YO UK N O WTYLI’s China office has long been the go-to bridge design and engineering firm for new structures in or near the rapidly growing municipality of Chongqing. Here are three of the firm’s latest bridge design projects in the region:

1 Egongyan Rail Bridge across the Yangtze River In a joint venture with SMEDI, TYLI provided complete design services for this new self-anchored suspension bridge, one of the most important components of Chongqing’s “Circular Line Transit System.” It will carry only metro rail and bicycle/pedestrian traffic. Completion is slated for 2018.

2 Guojiatuo Bridge across the Yangtze River TYLI is the designer of this new suspension bridge crossing the Yangtze River. The upper deck of the 4,606-foot-long bridge will carry eight lanes of traffic, and the lower deck is reserved for light rail.

3 Luzhou Bridge over the Yangtze River TYLI is the Engineer of Record for this bridge, which is the second crossing of the Yangtze River in Luzhou. The double-decker suspension bridge carries six vehicular lanes on the upper deck, with the lower deck reserved for light rail. The design of the portal-shaped towers was inspired by a desire to welcome guests from all over the world.

After 38 years of service, Kim Prishtina, Ph.D., P.E., retired on August 1, 2017, ending his 42-year career as a structural engineer and San Francisco Unit Manager. For many years, Kim was responsible for the project development and management of buildings and special structures. This includes his involvement in the design of major offices and hotel towers in Northern California, including 456 Montgomery Plaza and the Meridian Hotel, both in San Francisco, and the Pacific Renaissance Plaza in Oakland.

During the 1980’s, as TYLI solidified its reputation as a leader in transportation infrastructure, Kim served as Project Manager on the structural design of the BART Turnback and Yard in Daly City, California. He was also Principal Engineer for the MUNI Metro Turnback in San Francisco, which won the American Council of Engineering Companies’ Grand Conceptor Award in 1998. In 2000, Kim was named Unit Manager and supervising engineer for TYLI’s San Francisco office. He was promoted to Vice President in 2007.

Kim will be greatly missed by his TYLI colleagues. Long-time friend, Sajid Abbas, describes Kim’s contributions aptly: “We’ve been so fortunate to have Kim’s experience and guidance to rely on. He helped many engineers to thrive in their careers and it is hard to imagine this office without him!”

456 Montgomery Plaza was the first high-rise building in San Francisco to use an eccentrically-braced frame system. The building sustained no architectural or structural damage during the 1989 earthquake.

Dr. Kim Prishtina (front row, center) celebrated his long career with TYLI surrounded by San Francisco office colleagues.

Dr. Kim Prishtina, P.E., Retires after 38-Year Career with TYLIFellow colleague, Tom Ho, shares, “Kim’s tenure ran parallel to TYLI’s rich history and its long tradition of excellence in design. He helped the company achieve many milestones.”

Marwan Nader adds, “It’s a great end to a wonderful career. We wish Kim all the best in his new adventures after T.Y. Lin International.”

Kim earned his Ph.D. in Civil Engineering in 1973 from the University of Naples, Italy. Now that he is retired, he looks forward to spending more time with his grandchildren, his children, and his wife, Mary. >>>

El Salto Falls Street Bridge Featured in Aspire

The Summer 2017 issue of Aspire, the Concrete Bridge Magazine, features an article on the new El Salto Falls Street Bridge over Buena Vista Creek in Carlsbad, California. TYLI provided design engineering and construction management services for the project. Co-authored by TYLI’s Jay Holombo and Wade Durant, the article describes how TYLI developed

an innovative design for the El Salto Falls Street Bridge using high-performance precast concrete. This allowed construction to proceed without entering an Environmentally Sensitive Area, eliminating the lengthy process of obtaining a U.S. Army Corps of Engineers’ regulatory permit and averting construction delays.

TYLI’s design plan also utilized three-stage accelerated bridge construction, keeping all work outside creek limits. Complex operations included the placement of the precast girders for the end spans cantilevered over the creek, 30 feet past the piers, and placement of the 120-foot-long center span girders using a two-crane operation and a midair hand-off over Buena Vista Creek.

This past summer, the American Society of Civil Engineers, San Diego Chapter, selected the El Salto Falls Street Bridge as 2017 Outstanding Civil Engineering Project of the Year (Bridge Category). The American Public Works Association, San Diego & Imperial Counties Chapter, named the project 2017 Public Works Project of the Year (Structures Category $2 - $5 million). >>>
