Inspections 



Following construction, periodic inspections of the project should be 

 conducted. Inspections should focus on structural deterioration that affects the 

 functionality of the breakwater. Repairs should be made in a timely manner 

 to prevent further unravelling of the structure. Inspections should also 

 identify potentially hazardous conditions to public safety that may have 

 developed as a result of the structure. 



Operations and maintenance manual for local sponsors 



EM 1110-2-1617 provides a description of the requirements and guidance 

 for post-construction activities for a shore protection project. Specific 

 performance requirements and guidance for accomplishing the satisfactory 

 maintenance and operation of shore protection works, including coastal 

 structures and beach fill projects, are provided in Engineer Regulation 111 0-2- 

 2902. This regulation prescribes operations, maintenance, inspection, and 

 record-keeping procedures required to obtain the intended purposes of shore 

 protection projects. 



Post-Construction Monitoring 



A post-construction monitoring program to evaluate the functional and 

 structural performance of a detached breakwater project is recommended and 

 described in EM 1110-2-1617. Project monitoring will assist in both the 

 specific project's performance and with developing guidance and methodology 

 for future projects. A monitoring program will allow the identification of 

 specific deficiencies in the performance of a project for which modifications 

 may be made to better meet the project's objectives, and establish if a given 

 structure has sustained damage that may affect its functional capacity. The 

 coastal zone is a complex area; frequent storms can occur and coastal 

 processes can fluctuate over time. From the research standpoint, monitoring 

 of prototype projects, whether successful or not, will provide the data 

 desperately needed to improve design guidance. 



A monitoring program should be designed based on the site-specific 

 project. The program must consider not only data collection, but analysis 

 methods and associated costs once the data are obtained. There are several 

 types of basic data that are often included in a monitoring program (EM 1 1 10- 

 2-1617).
