| Special Report: Sorting through pipe materials, applications, and suppliers |
| October 29, 2009 CE News |
| Pipe is perhaps one of the oldest and most common products used in water infrastructure construction — potable water, wastewater, and stormwater. The amount of pipe of all types installed and, in some cases, ongoing failures caused by improper application or simply pipe reaching the end of its lifecycle, have spawned a highly competitive market, technology advancements, and a wide choice of materials and suppliers. CE News presents this special report to help civil engineers begin sorting through all of the pipe choices they face when designing water projects. |

| Importing pavement innovation |
| October 21, 2009 CE News |
The use of geotextiles in pavements is hardly a new thing. They can be commonly found between and within subgrade and base layers to mitigate the effects of poor quality materials, as a filter around subdrains, and along embankments for stabilization. However, the use of geotextiles as an interlayer between cementitious layers in concrete pavements is not common in the United States — at least until now. |

| 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. |

| 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… |
