An extensive survey was made at Naval facilities to determine the extent of decay of above water portions of waterfront wooden structures. The purpose was to analyze the decay problems encountered and to find suitable preventive and corrective measures. Seven areas were visited, four on the West Coast and three on the East Coast. Approximately 75 facilities were inspected. Serious decay was found in pier and wharf decks, curbs, chocks, wales, stringers, caps, and fender piles which resulted in serious and expensive maintenance problems. It was observed that much of the decay could have been prevented by using wood which was pressure treated with preservatives such as creosote, pentachlorophenol, copper napthenate or a fluor-chrome-arsenate-phenol mixture. It was concluded that no situation was observed for which pressure treatment of all wood components in a waterfront structure might not be justified. Further, Douglas-fir items will need supplementary treatment during construction and during later years.
