Dewatering is an essential part of the excavation phase of most construction projects, whether to mitigate groundwater infiltration or to remove accumulated stormwater. This practice is broadly termed ‘water control’, and can consist of ‘dewatering’ the subsurface below the excavation (using wells or well-point systems to control the water table), ‘unwatering’ the surface of the excavation (using localized mops/sumps), or a combination of the two.
It is common for the parameters of a water control project to be based upon a generic set of data (often generated from a previous project). Failure to measure and design for site-specific conditions can lead to widely inconsistent bids, significant schedule delays, and inordinate change order requests. Additionally, substantial liability may be incurred due to unanticipated changes in soil stability/bearing capacity, settling of adjacent structures, or unwanted influence on local contaminant plumes. Preliminary geotechnical, hydrogeological, and environmental testing are essential steps to defining the scope of any water control project.
ECC can provide labor and water control equipment, as well as expertise with design engineering, agency contact, and permit acquisition.
