Abstract
The Island of Montreal covers 450 km (super 2) in the middle of the St. Lawrence Lowland; it is located between the St. Lawrence River to the south and the Ottawa River to the northwest. The sedimentary rock basement of Cambro-Ordovician age is intruded by a Cretaceous pluton and breccia; the sub-horizontal strata are also cut by three systems of faults. Bedrock is found at shallow depth and the rock conditions for the foundations of large buildings are very good. Geotechnical problems related to surficial deposits are minor in the Montreal area. The problems encountered in underground works are related mainly to faults, dikes and sills and their associated fractures and alteration and to glaciotectonic disruptions in the upper part of the bedrock. The major expansion of construction in the last 30 years created an increased need to easily and efficiently access the geotechnical information collected in the numerous boreholes. In March 1972, the data from 25,540 boreholes were collected from geotechnical firms and municipal public works files; they were coded with the system proposed by the GSC at that time. From 1975 to 1979 the Laboratoire de Controle et de Recherche of the City of Montreal planned its own system, FIGARO, as a permanent and more comprehensive system for the consultation and filing of the ever-growing flow of data. The main task of coding and validating of 10,000 boreholes was done during the summer of 1982. The data bank has now increased to over 38.000 records, but the associated software suffers from a lack of performance and features. A new and more convenient way to make use of the data is now required.
