SAMPLING CRITERIA AND 



PROCEDURES FOR UNDERWATER 



INSPECTION OF 



WATERFRONT FACILITIES 



ABSTRACT Sampling criteria have been developed for planning and executing an 

 underwater inspection of waterfront structures. The proposed sampling criteria 

 use the scientific approach to sampling, where an estimate of the condition and the 

 extent of required maintenance is obtained, which guarantees that the inspection 

 will gather information that can be analyzed in a manner consistent with standard 

 statistical practices. Data obtained using these criteria can be compared to each 

 other with proven correlation procedures to indicate trends in deterioration rates 

 and allow more accurate projections of maintenance and repair requirements.
