What is the typical construction sequence when using precast concrete noise barriers?
After shop drawings have been approved, surveyors lay out the alignment of the wall and place stakes at each column location. Offset stakes are also provided in case of the accidental removal of an alignment stake. The contractor then begins the process of drilling and pouring concrete footings; the posts are then placed on or in the footings, depending upon which style is used. Once the posts are in place, the panels are then installed between the posts to the desired height.
