This $15.2 million bypass extension in Bethlehem, N.Y., was a pilot project for NYSDOT to test the integration of automated machine control grading and the use of Bentley technology’s quantity managing capabilities. Creighton Manning Engineering developed 3D digital terrain models (DTMs) and worked with the estimating software to meet the project goals. The quantity manager capability linked the InRoads DTM features to the pay items database.

The stakeless survey (grade control) technology was particularly useful for significant earthwork. Using the DTM and GPS-based survey and machine controls, the contractor moved over 200,000 cubic meters of earth in a relatively short time. The technology not only increased productivity but improved quality through improved accuracy. This technology also aided the inspector in managing quantities during construction.

Part of the western corridor into Brisbane, Australia, the Safelink Ipswich Motorway operates under peak demand with significant commute delays and poor safety records. This project includes the upgrade of 2.5 kilometers of centenary motorway; expansion of 5.5 kilometers of Ipswich Motorway from four to six lanes; earthworks and bridgeworks for a new rail line; a new multi-level interchange for road and rail; and civil works involving 30 bridges, underpasses, and drainage structures.

With the motorways required to be fully operational during construction, the design team had to focus on temporary works and staging as well as the ultimate design. Because a local skilled-labor shortage necessitated gathering team members from around the globe, the project team selected MXROAD and ProjectWise as intuitive design tools with the flexibility to operate on multiple CAD platforms and manage design data among offices.

A new six-lane elevated highway on the Delhi-Agra section of NH2 will pass through Delhi and Faridabad, India. This $100 million project includes construction of a complex interchange at Badarpur Junction and the widening of ground roads on both sides. The designer used MXROAD to produce the best alignment plans with the least impact on urban settlements and the Delhi Metro Rail project under construction along the corridor.

Since construction of the elevated highway and metro rail was simultaneous, design solutions were limited. The goals were achieved by a team of just three people using the MXROAD tools. The software integrated a range of tasks and enabled the coordination of design. Sight distances and visibility were checked and improved using the visualization tools. Bentley software saved 20 percent of the design cost and shortened the design schedule by 35 days.

West Des Moines is a rapidly growing suburb to Iowa’s state capital. The Cascade Avenue project, which borders the new headquarters for the world’s fifth-largest insurance group,was partially funded by the state program called Reinvesting in Iowa’s Sound Economy. The road project consists of a half-mile of new construction that will transition from a five-lane roadway with a continuous left-turn lane to a four-lane divided roadway with dual left turns.

MicroStation and GEOPAK developed a precise, 3D model of the corridor for contractors to use in pre-bid estimating and during construction with machine-control grading and earthmoving equipment. This helped produce a lower bid, minimize change orders, and decrease the construction schedule for an estimated 25 percent cost savings on construction.

LJB prepared a safety study and preliminary engineering plans for a 3.2-mile section of U.S. Route 40 near the Interstate 270 interchange in Franklin County, which has one of the highest accident rates in Ohio. The study analyzed more than 1,200 crashes from a three-year period. Traveled by nearly 40,000 vehicles per day, the five-lane corridor required $20 million in improvements, including traffic signal modifications and phasing, and access controls.

LJB developed phased construction plans to widen and replace pavement, and replace the antiquated closed drainage system. Bentley products seamlessly integrated the design process. Using 3D laser scanning to collect point-cloud survey data, LJB assembled the data into a 3D site map with Bentley CloudWorx and deployed MicroStation VBA to import data into GEOPAK, which eliminated human error.
