Community Infrastructure

Communities rely on critical infrastructure such as sewer and water services, water and waste water treatment, community flood protection, power and gas distribution, water retention structures, and communication services (buried fiber optics and communication towers). Each type of community infrastructure has its own unique technical aspects, many of which are geotechnical related that require special considerations in design and construction. Groundwater seepage and excavation stability are often controlling factors in the design of underground structures for these projects, and can also be crucial in the proper selection of installation techniques, for example open-trench or trenchless installation of buried pipes and culverts. The vital nature of community infrastructure means that efficient, reliable design and future maintenance considerations are key in delivering essential services to communities.
