The plant expansion at Willamette’s Surepine facility required the design of 21 pneumatic systems including low pressure conveying systems, high pressure conveying systems and dust collection systems.  Eagle/WPS personnel led the design and implementation of the project.  The design work was broken into two phases:

Preliminary Engineering

The scope of work included the development of preliminary layouts and budget estimates for the pneumatic systems associated with the addition of a new forming line and press.  General arrangement drawings, scope of work, and equipment specifications were generated for the bid packages.

Final Engineering

Once the project was approved, the final engineering on the pneumatic systems was performed. Final engineering included the design of all support structures and foundations for the pneumatic systems.

WPS provided complete fabrication and installation services for these systems.

The scope of work included the design of the exhaust duct between four plywood veneer dryers and a new RCO.  This duct was routed across the roof of the existing buildings which required extensive structural modification.

Dryer Exhaust Systems

These were “push-pull” systems with exhaust fans at each dryer and a large FD fan at the RCO inlet.  The design challenges included designing the ductwork in a way to balance the system with multiple fans, designing in a way that allowed adequate maintenance access, and providing for thermal expansion in the duct.

Structural Design

Extensive structural modifications were made to the existing building to support the new duct and to support maintenance platforms on the roof.  A structural analysis was performed of the existing building and columns were added in key locations to reinforce the frame.  In one location a truss was designed to fit under the existing building frame to reinforce it to carry the new loads.  New stair towers were designed to provide adequate access to the roof at both plants.  The scope also included the design of the foundations for the new RTO’s, fans, and structures.

WPS Industries provided all fabrication and installation services for these projects including the installation of the RTO’s.
