Leading the Future of Mobility

Mobility involves moving people between where we live, work, and play, along with transporting the goods and services that support or enhance our lives. As cities grow more congested and are plagued by aging transportation infrastructure, mobility planning becomes an urgent objective for urban environments.

TYLin recently introduced our Mobility Systems practice and our global team of experts in the design and delivery of innovative, real-world mobility solutions across physical and digital networks. According to Megan Huff, PfMP, TYLin’s Mobility Systems Leader, the timing couldn’t be better for cities across the United States.

“Nearly half of all U.S. bridges are over 50 years old, and more than 40% of public roadways are overcrowded and outdated,” says Huff. “And even if more people decided to start using public transportation, 45% of Americans don’t have any access to it.”

Modernizing transportation infrastructure is a massive undertaking on a physical scale. For example, roadways need modernization, transit systems need extensions to connect outlying areas, and communities increasingly demand active transportation options.

However, while we have the technology to upgrade transportation systems, there is another issue facing the U.S. transportation sector. Creating smart cities involves large-scale technology integration, and urban areas have enormous volumes of data trapped in silos.

“Mobility planning breaks down those silos and creates vital data connections between transportation agencies,” adds Huff. “This not only improves the customer journey and operational efficiency, but it will also help realize the vision of a smarter, more integrated system in this country.”

TYLin’s Mobility practice comprises the combined vision and expertise of TYLin, GPO Group, A TYLin Company, Sam Schwartz, A TYLin Company, Ross & Baruzzini, and Integral Group. Prioritizing sustainability, innovation, and equity, we help develop smarter cities with more connected solutions. Here are some examples.

Urban Mobility: We combine the different transportation modes to create a seamless user experience and ensure that cities can accommodate and benefit from the changing mobility landscape. Solutions range from Complete Streets to Shared Mobility and Seamless Payment Models .

The South Bay Bus Rapid Transit (BRT) Project in Chula Vista, California, is a system that emulates rail service and increases user safety and convenience. TYLin completed the final design of Segment 2, consisting of close to 1.5 miles of dedicated BRT guideway, two stations, and a two-frame bridge.

Congestion Management: From Integrated Traveler Information to Traffic Management and Tolling, we blend industry-transforming concepts with data-driven analysis and implement them to manage congestion in critical areas .

For the Riverfront Square Traffic Impact Study + Parking Consulting project, Sam Schwartz, a TYLin Company, performed a traffic impact study and recommended improvements for the proposed Riverfront Square development in Newark, New Jersey.

Connected /Autonomous Vehicles : We help prepare cities for emerging technologies such as electric mobility and mobilityon-demand while continuing to work across all modes and prioritizing safety

TYLin designed structural components and associated infrastructure for part of the Automated People Mover (APM) system at Orlando International Airport in Florida. The system increases capacity and expedites traveler movement.

Customer Experience: To build ridership and system use, we help agencies and the public understand the value of a safe, efficient, enjoyable customer experience. Solutions include Station-Area Master Planning, Architecture, and Interior Design.

Sam Schwartz, A TYLin Company, led the transportation elements of an award-winning master plan to transform Uptown Pittsburgh, Pennsylvania, into a model “ecoinnovation district .”

Digital Transformation: Technology is continually evolving. We leverage big data sets to help clients better analyze system operations and effectiveness, including Turning Data into Solutions, Digital Enablement, and Automation

Amtrak engaged Ross & Baruzzini, a TYLin affiliate, to conduct a comprehensive study of the traffic control systems and control center facilities for its most heavily used passenger rail corridor in the United States. As a result, ways were uncovered to improve operations and security and reduce maintenance costs.

Energy Transitions : Our mobility team assists with the planning and implementation of fleet transition strategies that pair with alternative fuel options to reduce emissions.

TYLin is working with the Regional Transportation Commission of Southern Nevada to develop its first Zero Emission Transition Plan and Facility Modernization Strategy. This will include operations and maintenance facilities for battery electric bus, hydrogen fuel cell electric bus, and zero emission paratransit vehicles.

Resiliency : We offer expertise in a wide range of resilience frameworks and targeted studies to enable better operations today while preparing for tomorrow’s shocks and stresses .

The 207th Street Yard in New York, New York, is a major New York City Transit (NYCT) facility that was severely damaged during Superstorm Sandy. TYLin is working closely with NYCT to rehabilitate the yard and protect it from future storm events.

Safety : Our safety specialists have an impressive record of reducing crashes and creating safe travel for everyone. We design urban improvements, pedestrian amenities, and Complete Streets that support Vision Zero ideals

After the City of Chicago, Illinois, launched its Vision Zero Action Plan to eliminate deaths and serious injuries from traffic crashes by 2026, Sam Schwartz, A TYLin Company, was tasked to support the Action Plan over five years.

Sixth Street Viaduct Opens to Public

LOS ANGELES, CALIFORNIA, USA

In 2015, the City of Los Angeles Department of Public Works awarded TYLin the task order to provide construction management services for the Sixth Street Viaduct Replacement project. The City’s new “ribbon of light” bridge opened to great fanfare on July 10, 2022.

The original landmark structure, constructed in 1932, used reinforced concrete with a distinctive steel arch spanning the Los Angeles River. Over the years, the concrete deteriorated due to alkali-silica reaction (ASR).

As a result, the structure became unable to withstand a moderate earthquake structurally and required a retrofit or replacement.

The new Sixth Street Viaduct is the largest bridge project in the history of Los Angeles and utilized the Construction Manager/General Contractor (CMGC) method of contract delivery. The USD 570 million bridge is 3,060 feet long and connects the downtown Los Angeles Arts District with the Boyle Heights neighborhood.

Spanning the Los Angeles River, multiple railroad tracks, and State Route 101, the post-tensioned cast-inplace concrete bridge features 10 pairs of arches and enhancements along local intersections to improve traffic flow. The project also includes the development of a much-needed recreational park for Los Angeles and Boyle Heights residents.

THE CITY OF LOS ANGELES’ “RIBBON OF LIGHTS” SIXTH STREET VIADUCT

Throughout the 7-year on-call contract, TYLin provided construction management during bridge demolition, pile installation, and superstructure construction; independent checking of the contractor’s extensive falsework design; post-tensioning installation quality assurance; materials inspection and quality assurance; geometric control and hanger installation monitoring; schedule and change order management; and coordination with the California Department of Transportation (Caltrans) and other agencies.

Site challenges included minimizing impacts on downtown traffic, working within the Los Angeles River and near active rail lines operated by five agencies, and managing right-of-way challenges and utility conflicts.

Overseas Highway over Spanish Harbor Bridge

FLORIDA KEYS, FLORIDA, USA

Through our Florida team of bridge rehabilitation experts, TYLin won the Florida Department of Transportation’s (FDOT) Overseas Highway over Spanish Harbor Bridge Rehabilitation Contract in the Florida Keys of southern Florida. Our team formulated a strategy for executing the design to address safety and bridge preservation measures, cost savings, and

Theconstructability.rehabilitation

of the SR-5/US-1 Overseas Highway Channel Bridge over Spanish Harbor Channel is a unique undertaking due to its remote location and the structural deterioration caused by an extremely aggressive coastal environment. TYLin has been retained by FDOT District Six to design a rehabilitation project to preserve this important structure and extend its service life.

TYLin performed a detailed engineering inspection, and we are currently diagnosing deficiencies and developing solutions to maintain the bridge’s safety and function. We used a high-speed camera to capture deficiencies like cracking and spalling on the bridge deck. Hands-on inspections of the beams were performed using a snooper bucket truck, and the substructure was inspected by boat.

TYLin will also be performing Service Life Modeling to provide an understanding of the rate of chloride intrusion and to project when corrosion will initiate on a component currently in good condition. The procedure will help FDOT in the decision-making process for the next round of bridge repair or replacement initiatives.

Steveston Interchange Project

METRO VANCOUVER, BRITISH COLUMBIA, CANADA

TYLin was selected by the British Columbia Ministry of Transportation and Infrastructure to complete the Independent Engineer services through the construction and demolition phases of the Steveston Interchange Project in Metro Vancouver, British Columbia, Canada.

As an integrated extension of the owner, TYLin will focus on reviewing the design and construction documentation and the project work for progress evaluation, including site and plant inspections. We are ultimately responsible for certifying statements of progress and advising the owner on the commercial aspects of the project.

The CAD 90 million project comprises the upgrade of an aging interchange and bridge with only two travel lanes. The new interchange will establish five travel lanes - two eastbound lanes and three westbound lanes – and a leftturn lane onto Highway 99.

There will also be improved ramp connections between Steveston Highway and Highway 99 and public transit bus priority measures to allow buses to move through the interchange more efficiently. These include traffic signal

priority at intersections and a dedicated bus lane and in-lane bus stop on the northbound offramp. Additionally, there will be dedicated walking and bicycling pathways on both sides of the new Steveston Highway overpass across Highway 99.

Construction faces numerous challenges, including myriad below-ground and above-ground utilities, a tight construction envelope, and very poor soil conditions. In addition, an extensive intelligent transportation system (ITS) network and counterflow lane infrastructure must be maintained for the duration of the work, presenting significant traffic control restrictions on the work.

The project is also highly linked to the upcoming CAD 4.15 billion Massey Tunnel replacement project located immediately south of the Steveston Interchange, which required TYLin to implement a series of non-disclosure agreement measures.

The project broke ground in July 2022 and has an expected completion date of mid-2025.

York Region Air Valve Venting YORK REGION, ONTARIO, CANADA

was retained by the York Region in Ontario, Canada, to address deficiencies identified on air valves and their associated valve chambers at various locations within the Region. Correcting these deficiencies will keep regional water infrastructure operating in good condition and able to provide a reliable and uninterrupted source of potable water to the community.

The work includes providing inflow protection to the air valves using vent pipes against flooded chamber conditions. Where required, the valve chambers will be repaired, rehabilitated, and improved from an operational perspective by introducing platforms to facilitate access for better servicing.

Air valves protect watermain networks by releasing air from the system during operation and protecting against surges during transients. In the event of a watermain break, air valves prevent pipes from

collapsing from a sudden vacuum and allow air to release during the recharging of the watermain.

To produce the chamber design drawings, TYLin will use sub 4Sight to carry out LIDAR scans at each valve chamber location. The 3D point cloud from the LIDAR scan will then be converted into a 3D Revit model by TYLin’s team in Panama. Our Panama team will also create 2D design sheets from the Revit model. TYLin’s Canada team will then use the design sheets to detail the modification, repair, and improvement work for each chamber and air valve.

The LIDAR Scans will be obtained using the Faro Focus LIDAR scanner. The scanner gathers information up to 70 meters away and is accurate to 2 millimeters at 10 meters from the scanner and 3.5 millimeters at 25 meters.

Touring the West Mission Bay Drive Bridge Replacement Project

SAN DIEGO, CALIFORNIA, USA

TYLin and the City of San Diego, California, presented a technical tour of the West Mission Bay Drive Bridge Replacement Project to the San Diego Chapter of the American Society of Civil Engineers (ASCE) this past July. The tour provided up-close information on the planning, design, and construction of this USD 150 million bridge replacement project, which is nearing the final stages of construction.

Attendees included 25 design professionals throughout the San Diego region, including representatives from the Cities of Carlsbad, El Cajon, and San Diego, the San Diego Association of Governments (SANDAG), and local consulting firms.

West Mission Bay Drive links the Sports Arena and San Diego Bay to the south with Sea World and Mission Bay Park to the north. When complete, the new bridge will consist of two parallel 1,300-foot-long structures that provide an improved transportation link across the San Diego River. Each structure will carry three lanes of vehicular traffic and a 12-foot-wide barrier-separated shared-use path.

Architectural features include curved soffits and exterior girders, colored and textured surfaces, and aesthetic railings and lights. Other improvements include the reconfiguration of the westbound Interstate 8 offramp, widening of West Mission Bay Drive, stormwater enhancements, and water and sewer line replacement.

TYLin has served as Prime Consultant for planning, environmental documentation, design, and design support during the construction of this highly successful project. Located just over a mile from the Pacific Ocean, the new bridge is designed to withstand the effects of flooding, sea-level rise, earthquakes, liquefaction and lateral spreading, and Fortsunamis.moreinformation,

Parker Boulevard Complete Streets Project

TONAWANDA, NEW YORK, USA

Construction has begun on the Parker Boulevard Complete Streets Initiative from Englewood Avenue to Sheridan Drive in Tonawanda, New York. TYLin’s design increases accessibility while reducing vehicular speeds and conflict points to enhance safety for pedestrians, bicyclists, and automobiles. Services included planning, public outreach, preliminary and final design, and cost estimating.

An extensive public outreach program led us to hold a two-day “Tactical Urbanism” event, where we temporarily applied elements of the proposed design to a two-block segment, including a mock miniroundabout at Decatur Road. The event garnered additional feedback and community buy-in.

TYLin also assisted the Town’s grant writer in securing a funding source for construction through the Transportation Alternatives Program and Congestion Mitigation and Air Quality Improvement (TAP/CMAQ) Program administered by the New York State Department of Transportation.

The construction contract was awarded to Nova Site Company in early August. The project is one of New York State’s first fully designed Complete Streets treatments and includes three mini-roundabouts to be constructed at the intersections of Englewood Avenue, Decatur Road, and Harrison Avenue.

The Englewood Avenue roundabout corrects poor geometry and perceived safety risk while realigning a crossing of the Tonawanda Rails-to-Trails. The Decatur Road roundabout replaces an unwarranted and outdated traffic signal and emphasizes visibility and safety at a high pedestrian volume location in the middle of a large town park. In addition, vehicular travel lanes along the entire corridor are being narrowed to add continuous bicycle lanes in both directions and a parking lane along the southbound side of the street.

TYLin is providing office support to the Town and its onsite construction inspector during the construction phase. This project is expected to be the model for future Complete Streets projects throughout the Town of Tonawanda and Erie County.

Ribbon-Cutting Celebration for El Portal Undercrossing

ENCINITAS, CALIFORNIA, USA

On August 14, TYLin joined residents and local leaders from the City of Encinitas, California, and the San Diego Association of Governments (SANDAG) to celebrate the grand opening of the new El Portal Undercrossing.

The new undercrossing is the first safe and legal pedestrian and bicycle crossing of the North County Transit District railroad tracks along this 2.5-mile stretch between Leucadia Boulevard and Encinitas Boulevard. It connects residents on the west to the local elementary school across the street and residents on the east to businesses and the beach within walking distance to the west.

TYLin began its involvement in the El Portal Undercrossing project in the late 2000s, serving as the prime engineering consultant from the planning stage through final design and construction. The bridge was constructed using accelerated bridge construction that allowed the entire structure to be installed in one weekend closure of the railroad.

The aesthetics of the undercrossing were an integral part of the design. Designed with an architectural form liner, the retaining walls include frames blocked out for the future installation of mosaic tiles to be created by a local artist in cooperation with students from the local elementary school. The project had a construction cost of USD 7 million and was funded through an Active Transportation Program (ATP) grant and local funds.

The grand opening of the new El Portal Undercrossing was met with great excitement and enthusiastic use. During the ribbon-cutting ceremony, residents used it to reach the local farmers market, and some people even carried their surfboards past the podium on their way to the beach.

Residents and city officials gathered on the west side of the undercrossing to celebrate the grand opening.

100% Design Milestone at Port Everglades

FORT LAUDERDALE, FLORIDA, USA

In early August, TYLin and its consultant team reached the 100% design milestone on the first two bulkhead replacement projects at Port Everglades in Fort Lauderdale, Florida. These Group 1 projects involve the replacement of close to 3,500 feet of bulkhead walls at Berths 3, 2, 1, 1A, 1B, 1C, and 1D (BERTHS) and the North Bulkhead at the Entrance Channel (NBEC).

The combined estimated construction cost is USD 53 million. TYLin will provide bid and award, post-design, and CEI services during the 2-year construction phase starting in 2023.

The BERTHS are in Northport and face Terminal 2. They are used by Princess Cruise Lines and Holland America Lines, and face the newly expanded Greater Fort Lauderdale Broward County Convention Center, now under construction. The NBEC faces the port’s entrance channel. While each project employs different bulkhead systems and have unique challenges, they both call for the new bulkhead walls to be built in front of the existing structures.

The bulkhead walls for the BERTHS are 2243 feet long. Engineering the first 100 feet of the bulkhead walls was the most challenging due to conflicts with existing toewalls, soil anchors, five existing high-capacity bollard foundations (HCBs), and one new HCB for Disney Cruise Lines.

The NBEC involves a close to 1250-foot-long cantilevered wall system. It follows the perimeter of a large, landlocked grass area fronting several homes and a 17-story condominium

include waterside construction, mitigation of impacts on seagrasses, and avoiding a sea turtle nesting site. Engineering determinants include a varying mudline elevation and high scour and wall undermining potential from strong tidal currents and vessel wakes. An extended concrete cap to encase the sheet piles’ splash and tidal zones will protect them from corrosion. Erosion and scour protection are provided using a concrete mattress placed at the mudline and a 3-foot concrete apron landside on-grade and right next to the new bulkhead cap.

Muskegon Museum of Art Expansion

MUSKEGON, MICHIGAN, USA

Originally opened in 1912, the Muskegon Museum of Art in Muskegon, Michigan, is currently undergoing its first expansion in 30 years. Silman, A TYLin Company, is providing structural engineering services for a two-story, 22,000-square-foot addition that will more than double the museum’s exhibition space, allowing it to showcase more of its 5000-piece collection. A new north-facing entrance, rotating galleries, and a roof terrace will all help to elevate the visitor experience. There will also be a dedicated space for works created by women artists. The project is expected to be completed by 2024.

The museum addition will be steel framed with a concrete composite acoustic deck. The lateral system consists of steel braced frames and concrete masonry unit (CMU) shear walls. Silman considered the deflection and vibration of structural slabs to ensure adequate stiffness and minimize cracking of the polished concrete gallery floor finishes.

Careful consideration of fire separation was also required. Silman designed for several fire conditions to allow for varying structural elements to break away to contain a fire and minimize damage.

Muskegon, located about three hours away from Silman’s offices in Chicago, Illinois, and Ann Arbor, Michigan, is the most populous city along Michigan’s western shore. Since expanding to the Midwest in 2019, Silman has been able to provide services to longtime East Coast clients like Annum Architects in a wider geographic area.

This project has also benefitted from Silman’s expertise in new additions to existing adjacent buildings, particularly cultural institutions. Other Midwest projects on the boards include the revitalization of Michigan Central Station in Detroit, a structural study of the Illinois State Capitol Dome in Springfield, and several private residences.

Another Award for Grist Mill Bridge

HAMPDEN, MAINE, USA

The Northeast Association of State Transportation Officials (NASTO) has named the Grist Mill Bridge in Hampden, Maine, as a Northeastern Region winner in the 2022 America’s Transportation Awards Competition. The Maine Department of Transportation (MaineDOT) project, designed and built by TYLin, Advanced Infrastructure Technologies (AIT), and T Buck Construction, Inc., was recognized as the winner in the Best Use of Technology and Innovation Category, Small Project Group.

The 75-foot single-span Grist Mill Bridge features a firstof-its-kind superstructure using cutting-edge composite girder technology. The five fiber-reinforced polymer (FRP) composite girders, which will significantly reduce maintenance costs, are expected to ensure a useful life of 100 years.

The FRP composite beams were developed at the Advanced Structures and Composites Center by the University of Maine and AIT. TYLin led the project management, engineering, and construction support effort for the USD 8.9 million project.

In 2021, the Grist Mill Bridge was recognized as the Kitty Breskin Project of the Year by the Maine Section of the American Society of Civil Engineers.

Historic Facilities Recognized at AIA DC Awards

WASHINGTON, DC, USA

Silman, A TYLin Company, provided structural engineering services for multiple projects that recently received Design Awards from the American Institute of Architects DC Chapter (AIA DC). These projects, all involving historic structures, have enhanced the educational and cultural fabric of Washington, DC, the nation’s capital.

The renovation of the Hyde-Addison School, completed in 2019, upgraded and merged two century-old public facilities into a single, cohesive campus in DC’s Georgetown neighborhood. A brightly colored, 30,000-square-foot addition links the existing structures and provides a new gymnasium as well as other specialized areas. This LEED Gold-certified project was part of a major DC government modernization and stabilization effort, a multi-billion investment in the city’s K-12 schools.

Across the city on Franklin Square, another historic school building received an award for its transformation

into a voice-activated language arts museum. The Franklin School, designed by Adolf Cluss and originally opened in 1869, was one of the earliest co-ed high schools. It was designated as a National Historic Landmark in 1996.

A careful renovation of the five-story, 50,000-squarefoot Renaissance Revival structure introduced a restaurant, 10 immersive galleries, an auditorium, a language laboratory, and more. In addition, Silman carefully modified the ceiling of the building’s Great Hall to support a 15-foot-diameter LED planet display while also meeting the needed loading capacity for a new event space located directly above.

The third award-winning project is the renewal of the Martin Luther King Jr. Memorial Library. Silman designed structural upgrades and modifications to the facility, which was designed by celebrated architect Mies van der Rohe and is now listed on the National Register of Historic Places.

WuYun Lake Park and Kowloon Bund Win 2022 IFLA AAPME Awards

CHONGQING, CHINA

Two TYLin projects in Chongqing, China - WuYun Lake Park in the Shapingba District and Kowloon Bund in the Jiulongpo District - have won 2022 awards from the International Federation of Landscape Architects (IFLA). WuYun Lake Park received an Honorable Mention in the “Wildlife, Biodiversity, Habitat Enhancement or Creation” category, and Kowloon Bund received an Honorable Mention in the “Social and Community Health” category.

Kowloon Bund in the Jiulongpo District creates a resilient riverfront that uses “seasonal use” as the design concept. The long-term goal of the project is to restore and revitalize urban life back on the north bank of the Yangtze River. The project includes 1.8 kilometers of retaining walls and restored 26 hectares of land that fluctuate seasonally.

Featuring a multi-tiered public space, Kowloon Bund provides space for diverse activities, such as shopping, special events, leisure, and physical fitness. The new cultural and environmental zones respond to the river’s dramatic water-level fluctuations while maximizing the protection and restoration of the Yangtze River ecology.

WuYun Lake Park is an ecological restoration project with a design that has to address various challenges, including the park’s use as a reservoir and local mountainous terrain.

The site is lusciously planted with various plants and trees that display different-colored leaves, depending on the seasons. The greenway around the lake also provides 2.1 kilometers of barrier-free access.

Offering smart technologies in a natural environment, WuYun Lake Park features a road with fluorescent materials that absorb sunlight during the daytime and form a luminous pavement at night.

The IFLA AAPME Awards 2022 is an international design award organized by the IFLA Asia Pacific region (APR) in collaboration with IFLA Africa and Middle East regions. IFLA is a UNESCO-directed organization representing tremendous professional influence in international landscape architecture.

TYLin at 2022 NASTO Conference

HARTFORD, CONNECTICUT, USA

TYLin staff members attended the recent 2022 Northeast Association of State Transportation Officials (NASTO) Conference in Hartford, Connecticut. The three-day event was used to promote TYLin’s Alternative Delivery Method (ADM) Group and the Roads + Highways and Bridge sectors.

NASTO brings together representatives from state transportation departments across the northeastern United States and the Canadian provinces of Ontario and Quebec. NASTO members represent Departments of Transportation (DOT) in Connecticut, Delaware, District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Ontario, Pennsylvania, Quebec, Rhode Island, and Vermont.

TYLin made new connections with delegates of both Connecticut DOT and MassDOT. We also met with members of the DOTs from Delaware (DelDOT) and New Jersey (NJDOT) and made additional post-conference meeting plans with staff from several DOTS and other consulting firms.

TYLin’s key messaging focused on our new sector alignment and our ability to provide services with a broader pool of resources while maintaining our local knowledge, expertise, and connections.

For ADM, we emphasized the support provided across sectors and geographies that allows us to excel at implementing best practices and identifying and managing risks.
