ABSTRACT: During construction of a water treatment plant addition, the existing structure suffered significant damage, had to be removed from service and a forensic investigation ensued. Ground and structure responses to the adjacent excavation were evaluated using analytical methods and finite difference numerical modelling. Input parameters for the soil constitutive model were calibrated to laboratory data and preloading responses of the site predating construction of the original treatment plant. The numerical model simulated the entire construction history of the existing building and neighbouring excavation. The numerical modelling, coupled with analytical evaluation of other contributing ground displacement mechanisms, corresponded to displacement measurements and remedial grout volumes, and provided valuable insight into issues that are vital in selection, design, and construction of excavation support systems.
