Maintenance and repair of steel structures and components fall into
five general categories: coating and wrapping, cathodic protection, concrete
encasement, partial replacement, and complete replacement.

PLANNING THE REPAIRS. Repairing steel structures are often
controlled by the availability of skilled personnel and equipment. In many cases,
structural repairs, particularly of bearing piles and sheet piling, will be done by
contract.
The initial planning step for establishing the repair approach must
involve review of prior inspection reports to determine the scope of damage or
deterioration, the rate of deterioration, and specific operational constraints placed
upon the facilities because of the deterioration. Once the scope of repair
requirements, including priorities, is established, how the work will be done,
whether in-house or by contract, must be determined.
8-2.1
Special Skill Requirements. Repairing the pier decking and curbs,
pile caps, fender system, and deck hardware involves having skills common to
in-house shop forces. Underwater repairs require special skill levels that may not
be available with in-house forces. These include general diving capability plus
knowledge of:
removing marine growth
jetting or air lifting procedures
underwater cutting, welding and drilling techniques
underwater lifting procedures
application techniques for underwater protection coatings
wrapping materials used in underwater construction
8-2.2 Equipment Requirements. Repairing pier decking and curbs, pile caps,
fender system and deck hardware requires equipment common to in-house shop
forces. Equipment for bearing or sheet piling repairs, however, may include:
high-pressure water blaster
hydraulic grinders with barnacle buster attachment
hydraulic drill with bits
hydraulic power unit
oxygen arc cutting and oxy-acetylene torch equipment
