Excerpt from Marine Structures, Their Deterioration and Preservation: Report of the Committee on Marine Piling Investigations of the Division of Engineering and Industrial Research of the Research Council

The section of the San Francisco Bay area forming the northeastern por tion of the bay contained many large and valuable structures practically all of which had been constructed on unprotected wooden piles during the 40 years preceding 1920. While San Francisco Bay proper had since 1849 been known to be infested by marine borers, none Of them had been known in the northeastern section through which the waters of the San Joaquin and Sacramento Rivers were discharged.

In 1914 it was found that a species Of shipworm previously unknown in, or at least unrecorded from, these waters had attacked the dikes at the en trance to the Mare Island Navy Yard and other structures in this part of the rbay, and in 1917 signs of serious damage appeared in the dikes. Within the next four years practically every timber structure in San Pablo Bay and Carquinez Straits was destroyed, and those in Suisun Bay were attacked. Local engineers, chemists and biologists formed a committee for the purpose of endeavoring to devise protective measures. On account Of the magnitude Of the problem and its importance to all sections Of the country, members of this committee requested the National Research Council to organize the study on a nation-wide scale.

For this purpose the National Research Council organized the Committee on Marine Piling Investigations to study the preservation of wooden strue tures from the attack of borers and to conduct an investigation into the value and proper use of the various substitutes for timber Of which concrete is the most important.

Excerpt from Marine Structures, Their Deterioration and Preservation: Report of the Committee on Marine Piling Investigations of the Division of Engineering and Industrial Research of the Research Council

This report presents the results of work done by the Committee on Marine Piling Investigations of the Division of Engineering and Industrial Research of the National Research Council. In its work the Committee was assisted by the Divisions of Biology and Agriculture and of Chemistry and Chemical Technology of the Council, The Committee wishes to acknowledge also the generous contributions of funds and services by a large number of other agencies and individuals. Without these contributions it would have been impossible to have carried on the investigations which are reported in the following pages.

While these investigations were planned by the Committee, the credit for their administration is due to Colonel William G. Atwood, Director of Investigations for the Committee. Full credit is also due to Colonel Atwood and to Mr. A. A. Johnson, Assistant to the Director, for the writing of this report, with the exception of those sections for which other authors are indicated.

The Committee presents this report with the distinct realization that much remains to be done in future study on the several phases of the problem of the protection of structures in seawater. It is believed, however, that the work of the Committee has been brought to a stage where such a compilation as this of results already obtained is warranted and it is hoped that the data here brought together may be found to be of value to the engineering profession.
