SECTION 323114 - AUTOMATIC GATE OPERATOR AND …



This master should be used by designers working on Port of Portland construction projects and by designers working for PDX tenants (“Tenants”). Usage notes highlight a few specific editing choices, however the entire section should be evaluated and edited to fit specific project needs.

This section is under revision by the Replace Access Control System and new equipment is under selection. Significant specification revisions are expected.
