Engineered Solutions: New Bridge in Hawaii Forest Replaces Roadway Prone to Flooding
Acrow Bridge designed and provided a permanent bridge to Mocon Construction for vehicle and pedestrian use in the Keahua Arboretum in the Keahua State Forest in Kauai, Hawaii. Planted with native plants and vegetation introduced by the University of Hawaii, the arboretum also is enjoyed for picnicking, swimming, hiking, biking and horseback riding. The original route, a concrete roadway, had sunk over time and flooded after heavy rains. Safe passage over the Keahua Stream wasn’t always possib...
'Out of Tolerance’ before 'Out of Time'
DPR Avoids Construction Delays with Automated Verification Software By Kevin P. Corbley A general contractor avoided what could have been a significant delay in the exterior shelling of a new multi-story retail building by finding twisted, missing and poorly aligned steel beams in the interior structure. The company used automated construction verification software to analyze 3D laser scans of the steel framework to identify precisely where as-built conditions deviated from the design...
Hydroseeding Takes Root at the Panama Canal
In a country that receives more than 100 inches of rain per year, on slopes as steep as 45 degrees, controlling soil erosion is crucial. In 2006, when the $5.7 billion Panama Canal expansion project kicked off, headlines were awash with news about the engineering feats required to expand one of the world’s busiest shipping lanes. What received much less attention—but just as critical to the project’s success—was the stabilization of the banks along the nearly 50-mile-long canal. After seeding...
Sponsored: MicroStation CONNECT Edition - The Foundation of Efficient Civil Engineering Design Workflows
Most of us must work with various file formats, integrate multiple disciplines, and improve project workflow efficiency. With all the different applications used by the many consultants that collaborate on today’s design projects, a lack of interoperability between software products represents a huge risk. That’s where Bentley Systems comes in. MicroStation CONNECT Edition, and all Bentley BIM applications, are built on the same comprehensive modeling platform so that users can easily progre...
Vibration Control in Hospital Construction
A renovation of White Plains Hospital, a 123-year-old healthcare facility north of Manhattan, featured the construction of the new, steel-framed, six-story Center for Cancer Care. Long-span high-performing composite slabs were designed to support heavy booms over operating rooms and limit vibration that could adversely affect hospital occupants. Project Team Steel Decking Source: New Millennium Building Systems Architect of Record: Perkins Eastman Structural Engineer:...
Engineered Solutions: Barren Arkansas Roadside Springs to Life After Soil Amendments
After completing an open cut slope for a recent highway project, the Arkansas State Highway and Transportation Department (AHTD) encountered a difficult mitigation challenge: a soil bed totally unsuitable for organic growth. The highly acidic soil, composed primarily of clay, rejected initial attempts at sustainable vegetation and threatened to create a high erosion environment. Soil analysis confirmed the poor growth conditions. Clay content was measured at 50 percent; such high concentratio...
What Is the P3 Model? Can It Save Infrastructure?
Todd Danielson, the editorial director of Informed Infrastructure, spoke with several private-sector infrastructure executives to learn more about the public-private partnership (P3/PPP) model, how it works and if it can be part of the solution to the massive infrastructure problem in the United States and beyond. Danielson: What’s the status of infrastructure in the United States? Hopping: I think most of us agree, even Congress agrees across the aisle, that our infrastructur...
Drones Are Transforming Infrastructure Design
By Hugh McFall It’s increasingly common to hear the steady hum of a drone flying on a construction site. They’re being used to share progress updates, manage earthworks, perform cut-and-fills and much more. But there’s also an emerging use case for drones within the civil engineering space: as designers move from 2D toward 3D design and BIM workflows, the reality-capture data that drones provide are making a huge impact on their projects. In short, drones are the latest tool in the...
SunTrust Park: Project Collaboration Helps Meet Opening Day Deadline for Atlanta Braves

Moore Fabricator: Hirschfeld Industries Modeler/Detailer: BDS VirCon A photo shows the erection of the left-field terrace-level trusses. Architectural renderings describe the exterior east side. The Atlanta Braves called Turner Field home for nearly 20 years, but time had taken its toll on the stadium, and the team was faced with a structure that needed nearly $150...
Sustainable Restoration: Engineers Look to Stabilize and Revitalize Historic North Carolina Farm
By Scott King, Project Manager Vertical, unstable, eroding stream banks will be cut back and vegetated for stabilization. The historic Lochill Farm, nestled in the rolling hills of the Piedmont in the heart of North Carolina, has been a regional treasure for more than 200 years. Located just outside the town of Hillsborough, N.C., in the Upper Neuse River basin, the farm offers a unique landscape along Finches Branch stream and its tributaries, where horseback riders can enjoy...
