Appendix G 



Construction Cost Summaries for 



Alternative 2: Semifixed Plant 



This appendix provides the background for the cost estimate for the semifixed alternative at 

 Shinnecock Inlet given in Table 15. It is based on the Indian River Inlet costs as shown in 

 pages G2-G6 from the General Design Memorandum and Environmental Assessment: Atlantic 

 Coast of Delaware (U.S. Army Engineer District, Philadelphia 1984), 1 pages G7-G8 from "Sand 

 Bypassing System Selection" (Engineer Manual 1 1 10-2-1616 (Headquarters, U.S. Army Corps 

 of Engineers (HQUSACE) 1991)) and other sources as noted. Many of the costs have been 

 determined using the Indian River Inlet costs and converting to 1997 dollars using "Civil Works 

 Construction Cost Index System (CWCCIS)," EM 1 1 10-2-1304, dated January 1996 

 (HQUSACE 1996).
