The Ingenious Transformation of the Domino Sugar Refinery BROOKLYN, NEW YORK, USA

Silman, A TYLin Company, has built a strong portfolio of complex adaptive reuse projects that repurpose former industrial sites. At nearly half a million square feet, the circa 1880s Domino Sugar refinery building (Domino) in Brooklyn, New York, represents one of our crowning achievements in adaptive reuse.

Domino joins a growing list of key projects in this Buildings category. Other examples include Empire Stores, an office and retail development created from a series of coffee warehouses; Powerhouse Arts, a multi-disciplinary artist hub at a former central power station; and multiple projects at Brooklyn Navy Yard, including a nanotechnology production hub within a former shipbuilding facility.

The renaissance of the Domino refinery building started in 2007 when the hulking structure received a New York City Landmarks Preservation Commission designation for its exterior only, opening the door to future redevelopment.

In 2017, the architecture firm PAU unveiled a scheme that called for a new office building to be inserted within the footprint of the landmarked refinery walls.

Temporary bracing and shoring was limited to avoid interference with new construction.

Maximizing Adaptive Reuse Due to its industrial functions, Domino lacked normal floor plates.

That meant the designers had to start from scratch to create something that could be used as office space. The solution was to construct a new steel and concrete building with the help of a crane that was assembled inside the hollowed-out courtyard.

As the structural engineer for both the support structures and the new framing, Silman was able to limit temporary bracing and shoring to both the building exterior and within the future moat to minimize interference with the new construction.

“Adaptive reuse projects require knowledge of archaic structural systems, historic preservation, sophisticated reinforcing, and the integration of existing structural elements with new components,” says Silman’s Pat Arnett, PE, Principal in Charge.

“That was the key to our success with Domino. We brought a keen understanding of the complex sequence of bracing, demolition, and new construction.”

At the apex of the new 15-story building, perimeter columns bend in to form a barrel vault penthouse with a profile reminiscent of the refinery’s round arch-style windows. The new structure is fully enclosed by a glass façade that is inset by 12 feet from the historic brick shell. This creates a continuous moat that functions as a lightwell filled with native plants and trees.

Now, nearly two decades after shutting its doors, the old refinery has been reborn as a building within a building that houses Class A office space, tenant amenities, ground-level retail, a tripleheight atrium lobby, and a penthouse event space.

“The refinery building project is the centerpiece of an 11-acre redevelopment of the former Domino complex along the East River,” says Nat Oppenheimer, PE, TYLin Buildings Sector Leader, Americas. “That’s the power of innovative and sustainable adaptive reuse. It allows us to repurpose iconic structures and their environs to meet the needs of today’s cities and communities.”

INSIGHTS

High Praise from NYSDOT on Buffalo Skyway Effort BUFFALO, NEW YORK, USA TYLin has received the final Performance Evaluation from the New York State Department of Transportation (NYSDOT) for our work on the Buffalo Skyway project.

With high marks in each category, NYSDOT noted that TYLin is “highly recommended for work on future Highway Design Phase I-IV contracts.”

The Buffalo Skyway has been a crucial element of the Buffalo metropolitan transportation network for over 60 years, facilitating the movement of more than 40,000 vehicles daily. In 2019, TYLin was selected as the prime contractor to prepare a scoping study assessing the aging viaduct’s long-term viability. It is accurate to say that while our agility and adaptability were tested on this high-profile, accelerated project, they were never broken or compromised.

TYLin led the team of 32 TYLin staff members, five subconsultant firms, and several subcontractors to address environmental issues; provide economic impact and cost-benefit analyses; and deliver expertise in urban planning, geographic information system analysis, highway design, bridge inspection and design, traffic forecasting, surveying, public involvement, and stakeholder engagement.

Five months after the initial planning study began, NYSDOT accelerated the project from a concept-level planning study to a Scoping Report, Design Report, full Environmental Impact Statement (EIS), and Section 4(f) evaluation. The project team held dozens of public involvement and stakeholder meetings to complete the Scoping Report and produce a full Draft EIS/Design Approval Document/Section 4(f) evaluation for review

by NYSDOT, the Federal Highway Administration, and cooperating federal and state agencies — all in less than 13 months.

The initial study explored various concepts, including maintaining the existing structure, constructing a new one, or removing it with upgrades to the regional transportation network. The expanded Scoping Report included the analysis of more than 25 concepts. The EIS evaluated the no-build alternative, two new-build

14

alternatives, and all associated environmental and economic studies and visual impact analyses.

TYLin also managed the development and calibration of a full PTV Vissim traffic model. Additionally, the team provided preliminary design services for one of the build alternatives, a boulevard roadway and bridge over multiple rail lines.

“The Department is well satisfied with the high quality of the Scoping Report and the DEIS and is appreciative of the successful efforts of TYLin to keep the project on schedule. TYLin has been a very dependable prime consultant for this project.” - NYSDOT. Since this was a very high-profile New York State project, the TYLin team utilized a co-Project Manager approach to delegate and efficiently proceed with the various project elements. We had a very strong team for all involved disciplines and subconsultant subject matter experts, each led by senior staff members with similar project experiences.

Says Dennis Kennelly, PE, TYLin Co-Project Manager and Design QC Engineer, “We engaged key staff from other TYLin offices to provide the deep bench to achieve all that was required in such a short time. On the client side, we collaborated daily and at weekly team meetings with senior agency members and department heads. This level of collaboration was not only invaluable, but it was also executed very well. We truly performed as a single team.”

Although the Buffalo Skyway project is currently paused, the preferred alternative involves a 2.6-mile connector roadway, seven new bridges, removing three existing bridges, and enhancements to I-190. The removal of the Buffalo Skyway could unlock waterfront acres for recreation and development, reflecting the project’s potential to reshape the area’s mobility and economic landscape.

TYLin efficiently switched gears to produce a Scoping Report and full Draft EIS/ Design Approval Document in just 13 months.

The Buffalo Skyway carries over 40,000 vehicles daily, connecting New York Route 5 with Buffalo’s downtown core.

BOS Taxiway November Rehabilitation BOSTON, MASSACHUSETTS, USA As part of the Massachusetts Port Authority’s (Authority) 2023 Airfield Capital Improvement Projects solicitation, TYLin was selected as the Prime Consultant for the design and construction phase services to reconstruct Taxiway November and the end of Runway 22R at Boston Logan International Airport (BOS).

The project will repair, preserve, and extend the facilities’ service life, including reconfiguring taxiway geometry to meet the current Federal Aviation Administration (FAA) design standards and strengthening existing pavements.

Scope of work also includes the electrical infrastructure, cabling, and fixture replacement of lighting systems and guidance signs. The project limits extend from the northern side of Runway 15R-33L to Runway 22L, with a total length of approximately 7,000 feet on reclaimed land within Boston Harbor.

Historically, asphalt pavements in the project’s limits have been subject to severe rutting caused by slow-moving, fully-loaded departing aircraft. Converting the taxiway and

16

runway pavements to cement concrete pavement may be the preferred method, but the construction process would impact air operations more than asphalt reconstruction. To balance the impacts and service life of the construction, the TYLin team will develop and evaluate multiple reconstruction strategies, including superior asphalt mixes, cement concrete pavement conversion, and varying subgrade improvement techniques.

Taxiway November is an essential, low-visibility taxiway at BOS and the main taxiway route for the largest passenger plane, the Airbus A380. Careful consideration will be required when developing the project’s schedule, phasing, and sequencing, as well as close coordination with the Authority, FAA, and the airlines.

Our services for this project will include planning; geotechnical, civil, structural, and electrical engineering design; environmental permitting; bidding, award, and grant administration; and construction phase services.

Reuniting Rochester Neighborhoods ROCHESTER, NEW YORK, USA The City of Rochester, New York, has chosen a team to redesign and reconstruct the remaining 1.5-mile segment of its Inner Loop Expressway, extending from the I-490 interchange to North Union Street. Following the successful transformation of Inner Loop East in 2017 and the completion of the Inner Loop North (ILN) Transformation Planning Study in September 2022, the design aims to convert ILN into an accessible, multimodal boulevard with at-grade, traffic-calmed city streets and pedestrian and bicycle facilities.

This USD 100 million project will finalize Rochester’s transition from a divided city to a unified urban landscape, removing the ILN as a physical and visual barrier. It will reunite neighborhoods, restore a human-scale street grid, and enhance public access to the City’s riverfront and High Falls. The project aligns with the “ROC the Riverway” Vision Plan and Rochester 2034 comprehensive plan. It will create new housing opportunities, foster community-based development, and generate job opportunities.

As a member of the Stantec team, TYLin will provide civil engineering design for areaways and utilities while also delivering bridge architecture expertise. The TYLin team members include Dennis Kennelly, PE; Nate Buczek, PE; Mark Bellavia; Noel Shamble, AIA, NCARB, EIT; and Dan Fitzwilliam, PE.

TYLin will perform a comprehensive feasibility study to enhance safety, accessibility, and the transportation infrastructure.

connectivity, and aesthetic design features to elevate the urban streetscape. Our focus includes improving the look, feel, and character of historic downtown Caribou, aligning recommendations with current growth trends and potential future developments in the historic downtown district.

The study will address traffic volume, safety, and parking issues while developing ways to enhance active transportation connections. This initiative targets key areas, including the city’s historic downtown, local schools, community center, and the riverfront area along the Aroostook River. The study area includes Route 161/Sweden Street and 14 other streets.

As he leads this project, TYLin’s Project Manager, Chris Helstrom, PE, an Aroostook County native, will draw upon his local perspective and commitment to the community. Reflecting on Caribou’s economic decline after the closure of the Loring Air Force Base in 1994, Chris is passionate about implementing solutions that address traffic concerns, create inviting gateways, introduce cohesive signage, enhance pedestrian safety, and encourage non-motorized recreation. He will work collaboratively on this project with Tom Errico, PE, Shawn Davis, PE, Thomas Antz, EI, and Terri Blair.

Building on our commitment to service in northern Maine, TYLin is conducting similar studies for the Town of Fort Kent and the City of Presque Isle. Longtime teammate Rasor Landscape Architecture, a Maine-based landscape and urban design firm, joins us on all three projects.

Ultimately, the study will equip city officials with realistic options for future downtown upgrades. The proposed enhancements prioritize active transportation, increased

Widening Project on National Freeway No.1, Hsinchu to Toufen HSINCHU, TAIWAN Since the completion of the widening program on Taiwan’s Freeway No. 1 from Wugu to Yangmei, the freeway’s Taipei to Taoyuan section has regained its fast and convenient travel function. However, with the expansion and development of the Hsinchu County and city living area, the Hsinchu section of the freeway has become a recurring bottleneck.

This project poses a significant challenge in terms of design capability and the planning and arrangement of construction routes. However, given our deep understanding of the work required, long-term track record of collaboration with clients, and extensive experience with freeway projects, we successfully secured the contract for the South Section lot.

The Freeway Bureau is now promoting a program to widen Freeway No. 1 from Yangmei to Toufen by adding a viaduct on both sides, effectively mitigating traffic congestion between local roads and the freeway. The Yangmei to Toufen widening program is divided into two sections, with the Hsinchu to Toufen section occupying the South Section.

The total length for the South Section is 17.8 kilometers, including the 10-kilometer-long viaduct structures and 7.8 kilometers of embankment. With a total service fee of USD 72 million, the project represents TYLin Taiwan’s largest to date.

TYLin’s Taiwan office is providing design and construction supervision services for the project. The project will construct new viaduct structures within the limited space of a busy freeway and interchange and includes prestressed box girders, steel box girders, and precast segmental bridges. Additionally, there will be replacement work for the substructure of a freeway bridge affected by river erosion.

20

Project work will also introduce technologies such as Ultra-High Performance Concrete (UHPC), multi-spiral reinforcement bridge piers, precast bridge decks, and Bridge Information Modeling (BrIM) to accelerate progress, enhance quality, and ensure smooth execution. This will further elevate our capabilities in bridge design and construction supervision.

The project adds viaducts on both sides of existing roads.

Providing MaineDOT with Software Support FALMOUTH, MAINE, USA The Maine Department of Transportation (MaineDOT) is undergoing a significant software migration, transitioning from Bentley Systems’ MicroStation and InRoads V8i series to the OpenRoads Designer CONNECT Edition (ORD) series.

This shift is in preparation for specific projects to be delivered digitally. To facilitate this transition, TYLin has been developing a process that combines emerging technology with the Department’s existing CAD software. Through this endeavor, we have provided valuable insight into one of MaineDOT’s largest programs, positioning TYLin as a critical partner to our client.

Recognizing the importance of pavement preservation in maintaining Maine’s infrastructure, MaineDOT is committed to enhancing this category of projects. While traditionally delivered as “book jobs” with no survey and minimal project plans, in 2023, MaineDOT generated over USD 175 million in pavement preservation. With this heightened focus comes an increased emphasis on accurately estimating pavement quantities and rectifying pavement deficiencies.

Sound Transit E360 Light Rail Extension BELLEVUE, WASHINGTON, USA TYLin has issued the final as-built documents for the E360 Design Build Project in Bellevue, Washington, for the Kiewit-Hoffman-led team. This is the project’s final design milestone, with substantial completion and opening celebrations for the pedestrian bridge, station, and Eastlink Starter Line anticipated in 2024.

22

To facilitate the delivery of such projects, TYLin is developing a process that leverages existing CAD software and LiDAR (Light Detection and Ranging), a remote sensing technology utilizing laser light for precise distance measurements. This process involves collecting a truncated survey to assess pavement conditions related to cross slopes and rutting. The desired final surface is created using modified modeling templates. The variance between the existing LiDAR surface and the proposed model surface enables accurate estimation of contract quantities.

Developed through our understanding of MaineDOT personnel skillsets and desired outcomes, this process ensures the simplest and most effective effort in producing deliverables. TYLin’s Tim Kelley, with his excellent grasp of Bentley Software, and Shawn Davis, PE, with his intricate client knowledge, have proven to be an effective team.

KCM Interim and South Annex Base Electrification KING COUNTY, WASHINGTON, USA TYLin is working closely with King County Metro (KCM) in King County, Washington, on the electrification of two facilities — an Interim Base (USD 90 million retrofit) and a South Annex Base (USD 250 million new base) to add Battery Electric Bus charging equipment for over 350 battery electric buses. This project contributes to KCM’s goal of a 100% zero-emissions fleet by 2035.

The ongoing project review for the Interim Base is on track to conclude in December 2023, paving the way for construction to begin in the first quarter of 2024 upon the issuance of permits. The design of the project is 90% complete and features electrical charging infrastructure comprising steel gantry structures and chargers for approximately 120

battery electric buses. The TYLin team is performing an independent, expedited permit review of the project for the City of Tukwila, Washington, to support KCM’s project schedule goals and commitments.

TYLin’s role on this project will help advance KCM’s commitment to a zero-emission future. Their zeroemissions target is central to their Strategic Climate Action Plan, which strongly aligns with the County’s broader objectives centered around equity and social justice.

We are excited to be involved in a project that helps KCM progress towards their sustainability goals while contributing to a more equitable and socially just public transit system.

Update on New Boca del Cerro Bridge MEXICO The execution of the steel structure for the central span of the new Boca del Cerro bridge in Mexico for the Maya Train has been completed. With the work carried out by advancing in cantilevers, the onsite execution took barely two months, concluding recently with the closure of the central segment.

The structural conception of the bridge, designed by IDEAM, A TYLin Company, for Mota Engil, was based on two very demanding conditions. First, bridge construction must be executed independently of the Usumacinta River, Mexico’s largest river. Second, because the new bridge crosses parallel to the existing classic arch of Boca del Cerro, which has been in service since 1950, the bridge design cannot compete with its historic neighbor.

IDEAM’s proposed solution was to design the structure of the new bridge to be below the deck, allowing the crossing to integrate with the beauty of its natural environment and the old bridge.

24

With a main central span over the river of 160 meters, the new bridge is a composite steel and concrete truss painted dark green and embedded in two hidden compensation spans of 30 meters using a prestressed concrete box-girder. Execution advanced in cantilevers using movable gantry travelers, which transported the steel segments over the bridge to its final position without depending on the river.

IDEAM’s truss solution has proven the most successful, especially from the vantage point of the closest towns downstream. This is because the view of the new bridge is blurred behind the great arch of the circa 1950 crossing.

The new Boca del Cerro Bridge will be finished in less than one month, becoming the largest span of Mexico’s Maya Train system.

See time-lapse video of bridge construction here.

AERIAL VIEW OF TENOSIQUE VIADUCT.

Bridges in Section 1 of Maya Train Near Completion MEXICO Construction of the bridges for Section 1 of Mexico’s Maya Train is nearing completion. The three main viaducts of Section 1 (Tenosique, Candelaria, and Escarcega) were designed by IDEAM, A TYLin Company, for Mota-Engil México and consist of a deck with a twin composite (steel and concrete) girder and multiple simply supported spans of 40 meters.

The Tenosique Viaduct, the longest viaduct in the section at 2,920 meters long, and the Candelaria Viaduct, with a total length of 990 meters, have both been completed. For the 1,080-meter-long Escárcega Viaduct, the last steel span has been placed onsite, and workers are finishing the placement of the upper precast slabs and the reinforcement and concreting of the upper slab.

The decision to design these long three viaducts as a succession of simply supported spans has proven to 26

be the best solution for this project. It has allowed work to be performed concurrently on multiple fronts while leaving spans with lower crossings and their affected services for the final phases, avoiding interruption to the execution of the rest of the spans.

Finally, the 136-meter-long Palenque Station Double Viaduct, comprising precast prestressed concrete girders and an upper concrete slab, has also been completed.

IDEAM has carried out the conception and detailed design of the bridges in Section 1, collaborating with LAMAT Consorcio Tramo 1, led by Mota-Engil México, and has provided technical assistance during construction. Recal is the Mexican steel workshop that executed the steel structure of the three main viaducts.

Double Cantilever Viaduct Deck, Section 3 of Mexico-Toluca Interurban Railway MEXICO Construction by balanced cantilevers is progressing on the deck for the West access viaduct to the Vasco de Quiroga Station in section 3 of the Mexico-Toluca Interurban Railway Line. In recent weeks, the closing segment of span 3 has been executed. With the execution of the closing segments in every span, the deck stops behaving structurally as a double cantilever embedded in the central piers and becomes a continuous beam embedded in the two central piers and simply supported on the two abutments.

The total length of the concrete viaduct is 191.70 meters, divided into three spans of 58.7+85+48 meters. Construction is being executed using a double balanced cantilever construction system.

The concrete box girder is 11.5 meters wide and has variable depth, starting at 5.5 meters in the surroundings of the central piers and reducing to 3.45 meters in the center of the main span. For the execution of the deck segments, four formwork travelers supplied by VSL are being used.

The original viaduct project was developed by SENER. IDEAM, A TYLin Company, is collaborating with the contractor, OHLA, and providing technical assistance during construction, especially for controlling the instrumentation and the camber definition and checking of the deformed deck. IDEAM successfully addressed a critical phase in the deck construction processes by advancing in equilibrated cantilever, where it is essential to correctly monitor and adjust the deflections of the two cantilevers that connect with the closing segments to provide continuity to the deck.

GENERAL VIEW OF VMC, PART OF THE ELLINIKON PROJECT IN GREECE.

Detailed Design Completed for Vouliagmenis Mall Complex ATHENS, GREECE IDEAM, A TYLin Company, recently finished the Detailed Design phase of the Vouliagmenis Mall Complex (VMC) in Athens, Greece. The VMC will be located in Athens near Vouliagmenis Avenue and is included in the general development known as “The Ellinikon Development.”

The VMC project comprises a large, 650,000-squaremeter shopping center made up of three parts: the Mall, Retail Park, and Mall Offices. The development will include two below-ground parking levels and two to three mall floors above ground. In some areas, there will be an additional basement level and, due to the slope of ground level, some basement levels are staggered.

The Mall Offices component consists of four office modules arranged in two stories above the mall, giving these areas a total of four floors above ground.

The Retail Park is in the western part of the plot plan, with four independent blocks for retail use with two underground parking floors. Various roofs call for landscaped areas and many of them will include skylights. It is also worth mentioning the treatment of façades, which may require a dedicated metal substructure for support.

VMC Ellinikon Project Plan View.

Seismic design has been essential to ensuring the proper behavior of the structure due to the project location in an area of medium-high seismicity. The reinforced concrete structure has a standard grid of 8.50 x 8.50 meters for the general areas, with a mixed seismic resistance system in elevation, formed by a wall system (flat slabs + shear walls) for the basement levels and a dual system of frames and shear walls (beams + shear walls) from ground floor to roof levels.

IDEAM has been involved in the project from the beginning, working for the consulting, engineering, and architecture professional services firm IDOM in conjunction with the international architect AEDAS. The entire project was done using BIM360 technology, from conception to detailed design.

Building Bridges to Prosperity RWANDA, AFRICA

In 2023, volunteers from TYLin and ARUP, in collaboration with Bridges to Prosperity (B2P), successfully completed the construction of the Bishenge (Masuma) Hybrid Suspension Bridge in Rwanda. The 223-foot-long hybrid suspension bridge crosses the Gasumo River at the Nyamagabe municipality.

Working hand in hand with the local community, the team faced numerous challenges over the two-week effort. But, thanks to their determination and expertise, the new bridge now provides continuous safe passage for schoolchildren, especially during the rainy season when the river becomes dangerous to cross. It will also foster economic growth, empower businesses, and ensure access to vital healthcare services for the local community.

We are immensely proud of our volunteers, who contributed their time, skills, and unwavering dedication to this project. Their commitment to connecting people, places, and ideas through the power of engineering is truly inspiring. Learn more.

York Peel Emergency Repair Wins NASTT Project of the Year YORK REGION AND PEEL REGION, ONTARIO, CANADA The TYLin team was honored with the North American Society for Trenchless Technology’s (NASTT) 2023 Project of the Year - Rehabilitation Award for our collaborative efforts on the York-Peel Feedermain Emergency Repair in Ontario, Canada.

In 2022, two leak points were identified at the Humber River crossings of the York-Peel feedermain, a critical watermain that supplies approximately 30% of the water demand for the region. The TYLin and Robinson team completed a comprehensive and expeditious evaluation of rehabilitation solutions, ultimately implementing Carbon Fibre Reinforced Polymer (CFRP) technology.

This uncommon alternative to pipe rehabilitation actually enhances structural integrity and will extend the watermain’s life.

Along with the selected construction team, we were able to temporarily decommission and recommission 7 kilometres of pipe (18,000 cubic metres of water) and repair approximately 370 meters (1,215 feet) of feedermain with CFRP lining within a matter of months. The feedermain had limited redundancy, so completing the repairs in such a short timeframe was critical in minimizing additional stress on the existing water supply system.

Winning this award is a testament to the entire team’s innovation, dedication, and expertise, showcasing our commitment to excellence in infrastructure rehabilitation. We are proud to have looked beyond conventional industry standards to make this emergency repair possible and to spotlight the benefits of more advanced rehabilitation technologies.

La Concordia Arch Bridge Wins COAM 2023 Award MADRID, SPAIN The Official College of Architects of Madrid in Spain has honored the new “La Concordia” Arch Bridge with a Colegio Oficial de Arquitectos de Madrid (COAM) 2023 Award. The COAM Awards recognize the quality of architectural works, good professional practices, and exemplary initiatives that have contributed to disseminating the cultural values of architecture in society. These prestigious awards are among the oldest on Spain’s national scene, with this year’s awards marking the 51st edition.

IDEAM, A TYLin Company, was responsible for the structural conception and detailed design of the “La Concordia” Arch Bridge and for providing Construction Management services for the Owner, Junta de Compensación Parque de Valdebebas. The contractor was Ferrovial. The original bridge proposal, which was presented by IDEAM’s Francisco Millanes Mato and coordinated by the IDEAM engineering team and project architects Francisco Domouso de Alba, Lorenzo Fernández-Ordoñez Hernández and Emilio Rodríguez Jiménez, was the winner of a 2007 ideas competition in which there were 12 other entries.

The bridge design presents a modern architectural reference, creating an iconic gateway to Madrid from the T4 Terminal of the Madrid Barajas Airport. “La Concordia” arch bridge connects the T-4 Terminal with Valdebebas, crossing over the M-12 highway. With a main span of 162 meters, the longest span in the Madrid Region, the bridge has a total length of 214 meters and a width of 24.5 meters.

TYLin Attends Maine Transportation Conference AUGUSTA, MAINE, USA TYLin staff attended the recent 72nd Maine Transportation Conference in Augusta, Maine, joining over 700 attendees from across the state and Northern New England. The conference theme was “Smart Investments Strong Infrastructure” and featured a full day of technical and policy track discussions.

Topics included how smart infrastructure investments can bring substantial returns, adapting to the changing climate, intersections and roundabouts for safety, and legislative funding. Regional and national transportation leaders attended and presented at the event. In addition to hosting a booth, TYLin used the opportunity to network with staff from the Maine Department of Transportation, the Maine Turnpike Authority, the consultant community, and numerous municipalities.

The conference tested the attendees’ creative minds by offering two opportunities to showcase bridge-building talents. For the popsicle stick bridge competition, bridges were built in advance using only popsicle sticks, Elmer’s glue, and ten sheets of plain copier paper. For the inaugural accelerated bridge onsite competition, teams of four individuals had 30 minutes to build a bridge with supplies provided. Winners earned prizes based on the weight the structures could support.

TYLin’s Ben Smith took the second prize in the competitive and long-running popsicle-stick bridge contest, bringing TYLin’s string of first or second-place finishes to four consecutive conferences. TYLin’s team of Daniel Myers, Ben Toothaker, Ben Smith, and Jeff Legere tied for victory in the accelerated bridge contest, equaling the highest weight-bearing capacity of a bridge constructed of manila folders, masking tape, and popsicle sticks.

TYLin’s ABC Bridge entry tied for first place in the first year of competition.

TYLin Attends Maine Asphalt Pavement Association Conference

Supporting Local Maine Chapter of Engineers Without Borders

FALMOUTH, MAINE, USA

PORTLAND, MAINE, USA

TYLin continues to think creatively and differentiate itself from the competition. On November 7, we sponsored and attended the Maine Asphalt Pavement Association Conference, which drew construction professionals from the major asphalt companies in Maine, as well as the Maine Turnpike Authority (MTA).

With TYLin as an official event sponsor, Chris Taylor, PE, and Nick DiMariano of TYLin’s Falmouth office attended a fundraising event in support of the Engineers Without Borders-USA, Portland, Maine Professional Chapter (EWB-PMP). The fundraiser took place on October 12 at Custom House Hall in Portland.

The event provides vital insight into the direction of the industry, the latest technologies, and projected trends in production and pricing. This year’s keynote speaker was an economist from the State of Maine who examined the state’s aging demographics and the challenges our industry will face in building and maintaining a workforce in the coming years.

Event proceeds fund EWB-PMP’s water distribution project in El Progreso, Ecuador. Residents in El Progreso do not have reliable access to potable water. EWB-PMP volunteers are working with residents to develop a drinking water catchment and distribution system.

TYLin was the sole design engineering consulting firm in attendance, which provided us with a unique opportunity to network with the nearly 100 attendees, including members of the contracting community in Maine and public sector clients. Our participation also demonstrates our willingness to consider all design aspects, including routine maintenance and preservation.

Shawn Davis, PE, and Jim Ferguson, both from TYLin’s Falmouth, Maine, office, spoke one-on-one with industry experts and representatives from MTA.
