1. Mob & Demob 



Indian River Inlet (Appendix G, page G2 above) $25,000 



Using CWCCIS Code #20-Permanent Operating Equipment for FY83 to FY97 (Cost Index = 

 330.82 and 464.31, respectively) gives an increase of 40.35%. So $25,000 is converted to 

 $35,087.50. An additional conversion in CWCCIS for differences between construction in 

 Delaware and New York (FY97 Cost Index = 521.6875 and 531.3475, respectively) increases 

 the cost by 1.85% (say 2%). Therefore, Shinnecock estimate is $35,789.25 (say $35,800). 

 Shinnecock Inlet $35,800 



2. a. Operations Building 



Indian River Inlet (Appendix G, page G4)~ 1,290 SF facility at $50/SF $64,500 



Using CWCCIS Code #19-Buildings, Grounds and Utilities for FY83 to FY97 (CI = 



330.82 and 464.31, respectively) gives an increase of 40.35%. A $50/SF cost becomes 



$70.18, and when increased by the state difference of 2% becomes $71.58/SF (say 



$72/SF) 



Shinnecock Inlet-1,500 SF facility at $72/SF $108,000 



b. Utilities 



Indian River Inlet (Appendix G, page G4) $7,740 



Using CWCCIS Code #19~Building, Grounds and Utilities (see 2a. above) increases cost 

 by 40.35% so that $7,740 becomes $10,863.09. The state difference (2%) increases it to 

 $11,080.35 (say $11,100). 

 Shinnecock Inlet utilities $11,100 



c. Security 



Indian River Inlet (Appendix G, page G4) $5,000 



Using CWCCIS Code #19— Building, Grounds and Utilities (see 2a. above) increases cost 

 by 40.35% so that $5,000 becomes $7,017.50. The state difference (2%) increases it to 

 $7,157.85 (say $7,200). 

 Shinnecock Inlet security measures $7,200 



3. Mechanical Equipment 



a. Indian River Inlet water supply pump & engine (Appendix G, page G4) $22,300 



As per phone conversation with Mr. Johnny Green of Standard Gravel Company, 

 Franklinton, LA (manufacturer of jet pumps), a Caterpillar Model 3408 (8 cyl), 450 HP 

 engine costs approximately $37,000. The water pump itself costs approximately $7,000. 

 Total cost is $44,000. 

 Shinnecock Inlet water supply pump & engine $44,000
