CHAPTER XIV. 



Coat of Works Cost per Acre of Water Area Cost of Locks and Docks Cost of 

 Quay Walls Cost of Floating Docks Dock Gates Cost of Caissons Cost of 

 dredging. 



IT is difficult to compare the cost of different dock works on 

 account of dissimilarity in the physical characteristics of site 

 and strata, local rates of labour, and materials available, the 

 habits of the people, and their methods of working. 



The probable approximate cost of a projected work may, 

 however, be arrived at, based upon the cost per unit of works 

 executed; but such data can only be of value when applied 

 under conditions generally approximately similar.
