Application of Digital Photogrammetry in Trenchless Engineering

This paper introduces the application of photogrammetric methods in trenchless engineering applications including construction job site monitoring and three-dimensional underground utility mapping. Accurate three-dimensional representations of buildings, roads, and other utilities on the job site can be easily obtained through the processing of digital photographs using photogrammetric software. This provides an avenue for assisting contractors in quality control of their construction processes. The existence of telecommunication, electrical, cable, water, wastewater, and gas pipelines provide potential strike hazards for trenchless methods such as horizontal directional drilling. Subsequently, it is imperative that accurate as-built maps be generated. This paper demonstrates the use of digital photogrammetric methods through field trail of mapping and monitoring applications.
