In the last 30 years, the public has played an increasingly instrumental role in shaping the projects that affect their communities. From advocating for dedicated funds in order to renovate an aging public library to identifying specific social and economic impacts issues caused by right-of-way acquisition, the voice of the citizen has become an increasingly critical project component. The influence of the general public hasn’t happened by accident, but through the ability to design and implement successful public involvement programs, which is often a legal mandate.
ABCs of Bridges
According to the Federal Highway Administration's (FHWA) Bridge Inspector's Reference Manual, there are three basic types of bridges: arch-supported, beam-supported, and cable-supported bridges. Components common to each bridge type include:
Traffic forecasting is often compared to predicting the weather — it's not 100 percent accurate. However, traffic forecasting remains vitally important in transportation planning as it helps define future needs for the life of a state's transportation system.
Many people think that SEH Project Manager Sue Mason, PE, has the "Midas Touch." And, even though everything she touches doesn't turn into gold, it does, oftentimes, turn into a City Engineers Association of Minnesota (CEAM) Project of the Year Award.
When a major rainstorm rolls through a community, it has the potential to wash away gardens and lawn debris. In addition, it may carry pollutants directly into our stormwater systems, and eventually into our rivers and lakes.
New discharge permit standards require wastewater treatment facilities to achieve lower concentrations of pathogenic microbes, bacteria, and environmentally hazardous nutrients in their effluent. In order to meet these regulatory demands, some wastewater treatment plants are retrofitting their facilities with membrane separation filters. These membrane filters act as a physical barrier to suspended solids and replace the large round settling tanks used in conventional plants.
Snow-covered ground and frozen lakes, swamps, and ponds no longer signal the termination of wetland delineation work. Although the optimal time for completing wetland delineations falls during the traditional growing season from April – November, work may continue during the winter months to keep a project on pace.
Wireless communications is now a mainstay in our everyday lives. Mergers, acquisitions, and technological advances in the telecommunications industry drive the need for new telecommunications sites and/or updates to existing telecommunications towers and antennas. Installations and upgrades of telecommunications sites, from the planning phase to activation, can extend over multiple years creating an unpredictable construction season.
