Abstract
Utilizing GIS to Manage Engineering Quality Assurance
Track: Architecture, Engineering, and Construction
Author
Traditional engineering quality assurance of design and construction projects is extremely document-centric, relying on sheet numbers, structure numbers, and hand-measured distances of station and offsets from wood staking of multiple alignments. Newer technologies, such as model-based design, GPS and robotic total stations, allow us to cost-effectively locate all quality attributes of project elements in a single three-dimensional coordinate system. Once this data is brought into GIS, it can be overlaid onto CADD-based design model. Quality assurance data can now be seen in the context of the entire project, instead of being limited to traditional graphs, reports, and statistics. GIS also allows us to compare collected data against both the design model and the contract requirements much more quickly and error free than traditional review. Additional uses of the data include payment documentation based on quantities of work performed, and real-time updates of as-built project schedules.
