Challenges of Small Site Construction: Access Limitations, Earth Retention Systems, and Other Site Specific Issues

The sprawl of suburban development, requirements to update and expand existing water systems, and the desire to make use of all available land has made construction on smaller sites more common. Once conventional only in urban areas, the use of tiebacks and earth retention systems are being used in suburban and rural areas where existing development impedes on the construction site's boundary. A project completed recently in the Village of Orland Park, a southwestern suburb of Chicago, is a prime example of the constraints a small construction site places on a project. The project included the construction of a buried, concrete reservoir that would connect to existing reservoirs and a pump station. The site's location in the center of a residential subdivision and boundary with an elementary school presented issues associated with restricted access, the requirement of an earth retention system, and extensive communication between the Village of Orland Park, the contractor, and the engineer.
