Bentley Systems, Incorporated, the leading global provider of comprehensive software and digital twins services for advancing the design, construction, and operations of infrastructure, announced the finalists in the Year in Infrastructure 2020 Awards program. The annual awards program honors the extraordinary work of Bentley software users advancing infrastructure design, construction, and operations throughout the world. Sixteen independent jury panels selected the 57 finalists from over 400 nominations submitted by more than 330 organizations from more than 60 countries.
The geotechnical engineering finalists for Year in Infrastructure 2020 Awards for advancements in infrastructure are:
Golder Associates Hong Kong Ltd – Tuen Mun-Chek Lap Kok Link Tunnel, Southern Landfall
As part of Tuen Mun-Chek Lap Kok Link (TMCLKL), a strategic link that will connect Hong Kong, Golder Associates was tasked with designing and constructing a 5-kilometer dual two-lane subsea tunnel. The USD 2.33 billion tunnel will be the deepest and longest subsea road tunnel ever built in the country. They needed software that would support the complex geotechnical conditions and high water pressure on this project.
Golder Associates used Bentley’s geotechnical applications to help construct the tunnels with alluvium overlain, marine deposits, and thick sand fill. With PLAXIS 3D, they optimized barrette design to use 52 less barrettes, shortening 46 of them by 2.8 meters, saving USD 16 million, reducing construction time by two months and reducing carbon dioxide emissions by 1,500 tons. The link shortens travel time by 20 minutes and ensures economic growth in the area.
HDR Engineering – Oroville Dam 3D Seepage and Stability Modeling of the Tallest Earthen Embankment Dam in the US
Project Playbook: ProjectWise, SOILVISION
Oroville Dam is the tallest earth dam in the United States, rising up to 770 feet, and is the key element in California’s State Water Project. The dam is almost 40 years old, however, and the last two five-year inspections resulted in recommendations for an improved seepage monitoring program. HDR Engineering was tasked with developing that program and, due to the dam’s height and steep embankment, traditional design methods would not work.
HDR Engineering chose SOILVISION to help develop a 3D seepage and stability analysis of the model. Using a “layered cake” approach, they converted the model and develop surface meshes. With SOILVISION, they incorporated foundation topography and valley effects into the seepage analysis for more accurate calculations. HDR Engineering developed a mesh that contained 407,561 nodes and 222,930 elements, an extremely large mesh for a complicated internal zoned dam. They are now able to monitor the dam’s seepage level to comply with regulations.
Saidel Engineering SRL – Nine-story Residential Building above the Subway Tunnels in West Bucharest
Project Playbook: PLAXIS
In western Bucharest, Romania, a residential building is being constructed over existing subway tunnels. The estimated EUR 2.5 million structure includes nine aboveground floors and a basement for parking. However, it was the first time that a structure was being built over subway tunnels in the city. SAIDEL Engineering was tasked with reducing the influence of the building on the tunnel lining, providing a safe and cost-efficient foundation solution.
As a PLAXIS user for almost a decade, SAIDEL Engineering knew the best geotechnical application to use for this complex project. The team developed 3D models and compared the results to the original 2D models, providing confidence in the project’s foundation on the tunnels. The influence on the tunnel lining was analyzed for all the relevant stages of construction and during its operation lifetime. The project unlocks the potential of other areas in Bucharest over tunnels, providing a model to follow for other projects.

Chris Barron, Bentley’s chief communications officer, said, “The circumstances of the global pandemic have made the past few months a challenge for us all, and it is a testament to our users’ resilience that we received over 400 nominees for our Year in Infrastructure Awards program. While we are not able to present this year’s conference and awards ceremony in front of a live audience, the new virtual format gives us the opportunity to re-invent Year in Infrastructure and take full advantage of ‘going digital.’ Attendees can access our informative sessions in real time, or on-demand, making it easier for anyone to attend multiple sessions that might have ran concurrently. We are also providing new and exciting ways to engage with infrastructure thought leaders from around the world and to explore and share their innovative insights.”
