Foundation Sciences, Inc. is determining the feasibility of collecting information on the construction of underground works, especially those of the last twenty years. The gathering and quantitizing of this type of information is being performed for the Oregon and Washington areas as a pilot project. The first phase of the study is the collection of as much of the data as available about the geology, design, construction and performance of existing underground rock excavations and the tabulation of this knowledge for a data bank. To date, all information contained in the general data forms for 256 projects have been entered into the computer. Four general computer programs are employed to obtain accurate answers to specific inquiries and report writing demands. The Inquire and Print program is the only program necessary for the data user and is available to all terminal users at any location in the United States. Detailed operating instructions are included for this program plus a brief discussion of three other programs used to enter the information into the computer. The second phase of the study is the evaluation of data available with special reference to those items of design and construction affecting supports. Two projects have been selected for intensive study.
