The Year in Infrastructure 2007 - (Page 57) WestLink M7 leighton Westlink M7 is a 40-kilometer toll road in Sydney, Australia, that links three major motorways: M5 at Prestons, M4 at Eastern Creek, and M2 at Baulkham hills. Westlink M7 is a fully electronic toll road with no cash booths, so there is no stopping or slowing down to pay tolls. The two major interchanges with M4 and M5 have provided the biggest challenges to the design and construction team, because it involved the construction of more than 20 separate ramps at up to five different levels over some of the busiest sections of motorway in Australia. Adopting a standardized and automated design approach across all design teams using Bentley MX solutions has ensured efficient development of model data and presentation of drawings. Streamlining of the design workflow allowed the complex interchanges to be designed efficiently, on time, and on budget. Harlingen Downtown Drainage maverick engineering, inc The $2.5 million downtown drainage project is located in the downtown area of harlingen, Texas. The purpose of this project was to redirect storm drainage to the outfall east of Business 77 to prevent flooding south of the downtown area. The major challenges of this project included working around existing utilities and having enough ground cover for the boxes while keeping the slope required for drainage. Bentley’s StormCAD software made it easy to make changes and determine if different designs would get the results required. The reports created by StormCAD, along with the profiles, helped Maverick Engineering see where it needed to make changes and/or had a problem (for example, ground cover, inverted or no slope, or flooding). StormCAD also integrated with AutoCAD easily so that the firm could use street details that had been drawn in AutoCAD. BE AWARDS OF EXCELLENCE 57
