2-1.4.3 Maintenance. Maintenance is the recurrent day-to-day, periodic, or
scheduled work that is required for a facility to be used for its designed purpose.
It includes routine work undertaken to prevent damage or deterioration of a
facility that otherwise would be more costly to restore. The more common
concerns in maintenance of waterfront facilities are:
Painting and protective coating.
Routine replacement or mending of fender components (e.g., rub
strips) to prevent damage to ships and the pier.
Maintenance of utility systems to prevent outages.
Routine mending of protective plastic wraps.
Routine patching of small concrete spalls and cracks.
Maintenance of the cathodic protection system.
Chapter 3 provides details of maintenance procedures in addition to
2-1.4.4 Repair. Repair is the restoration of a facility to such a condition that it
can be used for its designed purpose. The repair is done by overhaul,
reconstruction, or replacement of deteriorated constituent parts or materials that
have not been accomplished through maintenance. The more common repair
projects for waterfront facilities are:
Replacement or reconstruction of fender systems.
Repair of eroded or failing quaywalls.
Repair and resurfacing of pier decks.
Reconstruction of major concrete spalls and cracks.
Chapters 6 through 10 provide details of repair options for waterfront
structures. These sections are organized to guide engineering and maintenance
personnel in selecting repairs to waterfront facilities. Each repair procedure is a
stand alone document, with the repair description on the left and the illustration
on the right hand page. In Sections 6, 7 and 8, repair procedures are numbered
(for example, TR-1; timber repair number one) to permit identification and
reference. For many of the repair procedures, problem definition and application
constraints are also provided to guide the user in selecting the proper repair
technique to match the problem.
TYPES OF FACILITIES. The types of waterfront facilities include:
