SUMMARY OF WORKSHOP SESSION ON SUBDRAINAGE--PORTLAND, OREGON
This paper summarizes the work session on subdrainage held at the 1973 Federal Highway Administration workshop on Water in Pavements in Portland, Oregon. All agencies represented in the session are using underdrains and horizontal drains of some nature with varying degrees of magnitude and varying degrees of success. There is minimum usage of perforated metal pipe in conjunction with filter cloth. Most agencies have developed a standard with regard to the conditions of placement of underdrain systems. The Occupational Safety and Health Administration (OSHA) requirements concerning shoring and cribbing of excavations were discussed extensively. Most states would be greatly affected by more stringent regulations on the part of OSHA. It was agreed that more consideration should be given to the maintenance of drainage systems than has been given in the past.
