One of the more challenging aspects of a modern grouting program is managing and assessing the large quantity of data generated by the project. Grouting information needs to be quickly accessible by the whole construction team and put into context with the surface data, subsurface details, optical televiewer logs, drilling records, QA observations, photographs, flow measurements, artesian pressures as well as with instrumentation and other key features. Understanding the effects of grouting in a large project such as Mosul Dam where there have been repeated grouting programs over an extended period adds another layer of complexity to the problem. Automated grout monitoring provides a wealth of information about each hole, but as with all grouting projects it is the details of the subsurface and previous programs that are needed to gain a full understanding. The USACE (US Army Corps of Engineers) SIMDAMS (Site Information Modeling and Data Management Solutions) tools and methods are being used on the Mosul Dam project to support both the current construction grouting efforts and the ongoing risk assessments and dam safety modification study of the project. The method develops GIS (Geographic Information System) based 2D models in plan, profile and section views along with a 3D model. Features are hyperlinked to a document library allowing the models to act as a visual index to project information. The 2D and 3D GIS models have been developed to aid in the quick display of data allowing both the construction staff to see current grouting data and risk assessment/dam safety modification study personnel to understand the details of the subsurface, of previous work and the impacts of current grouting. Models are delivered over the web to the Government of Iraq, to the on-site construction team and to the “reach back” team in the United States. These easy to use web based models allow users with no previous GIS experience to fully engage with the information that has been gathered to date. It allows the dam safety community access to a BIMlike (Building Information Management) model of an earthen embankment dam along with its foundation that is continually updated as progress continues on the project.
