Our Role

McNary Bergeron is providing construction engineering services for an aerial guideway that has over 200 spans. The guideway is built using a conventional overhead gantry that can accommodate a 150' span at a 1000' radius and an articulating gantry that can erect a 150' span at an extremely tight 400' radius. Engineering services include segment erection manuals, geometry control, falsework, independent review of equipment, and engineering support during design and construction.
