Abstract: As a part of the process of environmental site closure, an industrial waste impoundment required the construction of a large gravity earth retention system built from the top-down using the deep mixing method (DMM). The earth retention system (DMM Wall) is 3, 155 feet long and consisted of 4, 613 individual DMM columns arranged in a cellular configuration, installed to a maximum depth of 83 feet. The project team utilized a construction information management system (CIMS) with customized automated processes to: (i) rapidly prepare as-built reports; (ii) track the constructed position of each DMM column in three dimensions and perform calculations regarding verticality and overlap with adjacent columns; and (iii) collect and display other QA/QC data such as unconfined compressive strength. CIMS process outputs were displayed in near real-time on a data management and visualization platform. CIMS allowed for expedited acceptance of DMM columns and rapid identification, evaluation and resolution of over 50 non-conformities resulting in uninterrupted construction work flow and no schedule delays.
