The purpose of this project is to develop guidelines for the evaluation of the load capacity of pressurized pre-1970 normal to shallow-buried pipelines under static and cyclic surface loads resulting from construction equipment and activities.  The governing design conditions addressed in determining the load capacity are failures of girth and seam welds under axial or hoop stresses.  A set of guidelines defining safe construction activities around these pipelines are developed.
