The Hwy 212 Bayou Derriseaux Structures project involved the replacement of two bridges - a main structure and relief structure - over Bayou Derriseaux on Highway 212 in Cleveland County, Arkansas. The goal was to improve hydraulic capacity, comply with Arkansas Department of Transportation (ARDOT) standards and remove load limits. The new integral bridges, measuring 143 feet by 33 feet and 241 feet by 33 feet, feature two 11-foot-wide paved travel lanes with 4-foot-wide shoulders. One of the key advantages of these integral bridges is their durability. By eliminating expansion joints and ensuring structural continuity, they require less maintenance and offer superior performance in terms of structural integrity, seismic resistance, and ride quality. Michael Baker International played a crucial role in this project, providing roadway and bridge design plans, hydraulic and geotechnical studies. The project also involved acquiring additional right of way and temporary construction easements.

Happy Friday, Let’s flashback to one of the Tony Gee and Partners’s iconic projects, The Shard as the tallest building in the United Kingdom. Its proximity to a live rail corridor underscores the critical importance of maintaining structural stability and minimizing the impact of shoring excavation for its three-level basements on the transit infrastructure. Tony Gee provided expert analysis and review for this iconic project, focusing on: 𝐌𝐚𝐢𝐧𝐭𝐚𝐢𝐧𝐢𝐧𝐠 𝐫𝐚𝐢𝐥𝐰𝐚𝐲 𝐬𝐭𝐚𝐛𝐢𝐥𝐢𝐭𝐲: Ensuring the structural integrity of the nearby London Bridge Station. 𝐌𝐢𝐧𝐢𝐦𝐢𝐳𝐢𝐧𝐠 𝐠𝐫𝐨𝐮𝐧𝐝 𝐦𝐨𝐯𝐞𝐦𝐞𝐧𝐭: Limiting the effects of the Shard's construction, including its three-level basement excavation, on the railway tracks and equipment. 𝐈𝐧𝐝𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐭 𝐯𝐞𝐫𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧: Reviewing permanent works, construction methods, and temporary works to identify potential impacts on Network Rail assets. The fully staged analysis of the basement construction was performed using PLAXIS 3D. The model data and input parameters were devised using reported heave measurements from published case histories and calibrated against heave recorded during the demolition of Southwark Towers. This model allowed us to predict movements at all parts of the adjacent structures at every stage of the works. Tony Gee's involvement in The Shard project showcases our commitment to delivering innovative and reliable solutions for the most challenging engineering projects. #EngineeringExcellence #TonyGee #TheShard #StructuralStability #RailInfrastructure #CivilEngineering #PLAXIS3D #InnovativeSolutions

Of course Lunda is known for their award-winning and iconic major river crossing projects, but we're in the business of connecting on a smaller scale, too. The Bridges of Mower County project involved the replacement of four rural bridges on I-90 through Austin, Minnesota: the Dobbins Creek Bridge, the Business Loop Flyover Bridge, and the eastbound and westbound bridges at Turtle Creek. Work also included grading, concrete and bituminous pavement, utilities, and hydraulics. Additionally, as a design-build project, the scope included bridge design, structure design, hydraulic, and roadway design. Project challenges included complex traffic control and staging on high-speed, high-volume roadways; construction in and near environmentally sensitive areas; and challenging subsurface conditions. The project also required collaboration and cooperation with multiple local stakeholders. For properties adjacent to the construction activities, the team coordinated with businesses and residents, conducting pre-condition surveys and vibration monitoring services. Three of the structures were located over impaired waters and Lunda developed and implemented an extensive environmental management plan during construction activities. An environmental team was assigned, with key individuals responsible for stopping work if necessary, and every individual on the project was charged with the responsibility to alert the team and project management of any environmental concerns. This proved critical when an unforeseen scour hole below an old culvert outfall (undiscoverable during design or initial construction) caused the failure of an aggregate retaining structure. Lunda issued a stop work order and worked with MnDOT, the DNR, and the engineer, to develop and implement a solution, keeping the project on schedule and budget. They might not have their own movie (yet) but we think the Bridges of Mower County are worthy of a #FlashbackFriday post! #fbf #bridgeconstruction #infrastructure #bridges #transportation #construction #lundaconstruction #lunda

The group leading the Interstate Bridge replacement project released a document that offers insights into how a new I-5 bridge between Oregon and Washington would change travel in the region. Select highlights from the analysis show tolling of the bridge is not expected to cause significant diversion to the Glenn Jackson Bridge, some areas of the Fort Vancouver site could be affected by the construction, and travel times during rush hour should improve if the bridge is built.

Calculating the appropriate transverse slope for highways is crucial, especially in regions with high levels of precipitation, to enhance road safety 🛣️. This was evident yesterday on the M1 in Melbourne during light rainfall when the entire left side of the road became inundated with water. Consequently, visibility significantly decreased, creating a potential rear-end collision scenario and endangering drivers and their families. This issue gains further significance in light of climate change, where sudden and intense precipitation events are becoming increasingly common. Proper civil engineering in road design is essential for safety. 🚗 Austroads #CivilEngineering #RoadsDesign #Safety

Municipalities that only use one or two pavement preservation treatments are hurting themselves. Imagine you're building a house, but the only tools you brought to the job site are a hammer and drill. It's going to be tough to build that house, right? You need a full toolbox with the right tools for the job as the building progresses through different stages. Pavement preservation is similar. There is no one-size-fits-all treatment. As a city or county, not utilizing a full "toolbox" of surface treatments is setting yourself up to fail. #pavementpreservation #asphaltmaintenance #publicworks #infrastructure #construction #roads #Streets #engineering #civilenginering

"Unfortunately, we have taken things for granted for too long. We haven't done the appropriate maintenance, the appropriate upgrading. And so this is the result of that." Roberto Leon, a structural engineering expert with Virginia Tech College of Engineering has been quoted and interviewed by dozens of national and regional outlets since the collapse of the Francis Scott Key Bridge in Baltimore last week. Check out his NPR interview which aired on Morning Edition today. #BreakingNews #StructuralEngineering #Engineering #Infrastructure

Engineer: Baltimore collapse will change how bridges are built When the Key Bridge was built in 1977, bridge designers would not have planned for a strike from a ship the size of the Dali, Gunalan said, as they wouldn’t have expected a collision of that magnitude. Rachel Sangree, associate teaching professor at Baltimore-based Johns Hopkins civil and systems engineering department, agreed with Schafer...Read More>>> https://buff.ly/3JBu7tG #MitoInsulation #Insulation #ConstructionNews #Housing #Construction #MultiFamily #MultiFamilyRealEstate #MultiFamilyConstruction #MultiFamilyBuilding #CommercialInsulation #multifamilyhousing #multifamilyinvesting
