![]() ![]() Has all the engineering been completed incorporating civil and mechanical principles? Has adequate subsurface data been retrieved? If not, can it be performed during installation?.Has an appropriate crossing method been selected? Which method was used to select the crossing type?.Have all major crossing risks been identified and communicated to the client in advance of detailed design?.Is a wildlife assessment and archeological site investigation required?.Has an adequate ground elevation profile been provided in CAD format? Has the thalweg (river profile bottom) been identified?.Can the right-of-way or temporary workspaces change as the project progresses or are they fixed?.Which season is construction planned for? Has a local water source been identified? Are access roads required?.Have surface and subsurface obstacles been identified? If not, will another on-site investigation take place during construction?.Have all land and regulatory permit processes been initiated?.Has there been a thorough on-site planning investigation with buy-in from all project stakeholders?.This post is designed to act as a quick guide and to escalate risks to project owners that may not have otherwise been captured. Crossing methods such as HDD, microtunneling, direct pipe, guided auger boring, open cut, trenchless, trenched, semi-trenched, aerial, bridged should be evaluated using risk-adjusted techniques. Proper planning, front-end design, installation, and maintenance are critical components of a successful pipeline river crossing project. ![]()
