| Advances in wastewater collection and treatment |
| October 3, 2009 CE News |
| Wastewater collection and treatment arguably ranks among the most significant advances in public health in the United States. Yet today, the public is largely unaware of the civil infrastructure that has virtually eliminated diseases that spawned deadly epidemics in this country during the last century. Nevertheless, many aging municipal wastewater systems now need rehabilitation, replacement, or expansion, and new technologies and design tools are poised to take the wastewater industry to new heights in sustainability, energy efficiency, and cost effectiveness. |

| Redecking Michigan’s Cut River Bridge |
| September 15, 2009 Rebuilding America's Infrastructure |
| Like its famous younger cousin just to the east, the mighty Mackinac Bridge, the U.S.-2 bridge over the Cut River is known for its elegant construction and breathtaking views of Lake Michigan.
The 62-year-old structure became such a tourist attraction that in 1985 it was widened to accommodate sidewalks on each side for pedestrians who had previously braved passing logging trucks to snap photos from the railings. It was this widening project that added complexity to the Michigan Department of Transportation’s (MDOT) planned redecking of the historic bridge in 2008. |

| New technology speeds bridge replacement in Utah |
| July 15, 2009 Rebuilding America's Infrastructure |
| When it comes to bridge construction, time is not just a fourth dimension — it's a critical factor in determining the success of a project. Particularly when a replacement is involved, saving time reduces cost, minimizes disruption to the community, and enhances the safety of travelers and workers. Toward that end, the Utah Department of Transportation (UDOT) has implemented an innovative construction technique that enabled the replacement of 12 bridges in a two-month period during the summer of 2008 — an unprecedented achievement in the construction industry |

| Infrastructure projects rely on precision surveys |
| June 15, 2009 CE News |
| The ability to conduct precision surveys using robotic total stations and 3D laser scanners—in conjunction with powerful processing and analysis software—is broadening the application of geomatics technology in the civil infrastructure arena. The following three examples demonstrate how such technology can improve safety during dam rehabilitation and tunnel construction and provide high levels of detail for effective operation and maintenance of bridges and roads… |
