Abstract: Municipal pipe line installation projects are characterized to have a relative large excavation depth, quick backfill, short construction duration and long excavation support horizontal length. A case history of pipeline excavation project is presented in this paper to demonstrate the design, construction and construction monitoring aspects of the project site with a soft mucky soil layer.
