Runway Rehabilitation at MIA
MIAMI, FLORIDA, USA
TYLin was selected and recently completed negotiations for the Runway 9-27 pavement rehabilitation project at Miami International Airport (MIA). This marks the firm’s 3rd consecutive runway rehabilitation “win” at MIA.
TYLin’s world-class Aviation sector has a long history of providing services to Miami-Dade Aviation Department (MDAD). MDAD is an anchor client of the firm’s Aviation practice in South Florida, and we are very proud of continue our 40-year plus relationship with the Department.
The contract amount is USD 4,956,360 and the term of the contract is six years. The contract goes before the Board of County Commission for approval in October.
Scope of work includes overlaying the runway and associated taxiways with asphaltic concrete surface pavement, upgrades to the runway edge and centerline lighting, pavement grooving and restoration of pavement markings.
The total project area includes the runway and extends to the existing taxiway hold bars to the north, the runway shoulder to the south, and the blast pads on either end of the runway. Since Runway 9-27 intersects with Runway 12-30, the rehabilitation will also include the intersection pavement extending to the northern and southern edges of Runway 9-27.
Maintenance of Traffic (MOT) and phasing will be critical components of the project to provide for the safe and efficient execution of the construction while minimizing impacts to airport and airline operations.
We are excited to begin design on this important project, and are looking forward to working hand-in-hand with MDAD staff to successfully deliver yet another challenging aviation project at MIA.

Zaoqiao Interchange on National Freeway No. 1
ZAOQIAO TOWNSHIP, MIAOLI COUNTY, TAIWAN
Zuoqiao is located in northwest Miaoli County in Taiwan, where National Freeway No. 1 passes through. However, travel for local traffic is inconvenienced by the fact that the two nearest interchanges are both seven kilometers away from Zuoqiao.
As a result, the Freeway Bureau launched the Zuoqiao Interchange Project on National Freeway No. 1. The project includes constructing interchange ramps, relocating a weigh station, and widening the access road to improve traffic capacity. The project will not only provide a better transportation service for residents, but it will also promote local tourism and industrial development for Zuoqiao.
TYLin’s Taiwan team has been contracted for the planning and design of numerous interchanges in the country, including the Shulin interchange of Freeway No. 3, Ganshan 2nd interchange of Freeway No. 1, and Gaoyuan interchange of Freeway No. 3. This demonstrates that we understand the needs of the Freeway Bureau as well as the specific challenges and characteristics of this project.

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 constructability.
The 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.

RENDERING OF THE NHHIP IN HOUSTON, TX

HOUSTON, TEXAS, USA
TYLin will serve as the Bridge Design Lead for the North Houston Highway Improvement Project (NHHIP) Segment 3B in downtown Houston, Texas. We are a member of the IDCUS Team that was awarded the design-bid-build contract for the Texas Department of Transportation’s USD 400 million interchange project. NHHIP Segment 3B is the second project to be awarded as part of the program to reconstruct Interstates 69, 10, and 45.
The NHHIP is a planned reconstruction of Interstate Highway 45 from south of downtown Houston to the North Sam Houston Tollway. Included in the reconstruction is Interstate Highways 10 and 69 in downtown Houston, as well as the Segment 3B interchange of Interstate 69 and State Highway 288. The segment of the project awarded to IDCUS and TYLin involves the main lanes of SH288 and US69 where they merge at a multi-level interchange in southwest downtown Houston. The project includes more than 10 new and replacement bridges. TYLin’s primary focus will be the design of three multi-span tied arch bridges that will create the most visually identifiable elements of the project.
The proposal and interview presentation by TYLin’s Dan Fitzwilliam, William Detweiler, Steven Skeele, and Allan Lapidario emphasized a winning technical approach that highlighted TYLin’s vast experience in the design and construction of complex bridges in an urban environment.
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.

EXAMPLE OF THE INTERIOR OF A VALVE CHAMBER WITH AIR VALVE, GATE VALVE, AND SAMPLE POINT

York Region Air Valve Venting
YORK REGION, ONTARIO, CANADA
TYLin 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.
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.

Design professionals observe the partially completed bridge deck on the ASCE Technical Tour. 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 tsunamis.
