Use Pier Protection Barrier (PPB) when bridge piers require protection. Example Layouts for PPB are shown in Index 521-002. For determination of PPB applicability, see the Pier Protection Selection Flowchart in FDM. The purpose of this Engineering Directive is to introduce updated MassDOT guidelines for the protection of bridge piers and abutments. The guidelines on the following pages supersede the corresponding guidelines contained in Part I of the 2013 MassDOT LRFD Bridge Manual. Cables tha are laid close to the surface are vulnerable to damage from the passage of heavy traffic. The first line of defense is to position bridge piers on land or in shallow water, if possible, to avoid having ships be able to reach the bridge piers. Figure 2: Cable-stayed. This standard requires the inclusion of standard BPPS-2B in the set of plans. below ground line to top of 2'-0” x 2'-0”.
