Multnomah County’s central courthouse was built between 1909 and 1914, when the county had only 250,000 residents and long before modern building code standards for the region’s risk of earthquakes were in place. The new Central Courthouse Project is a swiftly rising, 17-story-structure at Southwest First Avenue and Madison Street, and is slated for completion in the spring of 2020.

The beginning of the exterior envelope can be observed as the installation of the façade exterior window is ongoing. Leading up to the current stage of construction, the team engaged in numerous studies for cladding systems and curtain wall assemblies. During the design phase, 3D modeling was used not only to design and conceptualize the project but also to create prefabricated materials and choreograph different systems.

A free-standing mockup has been used extensively by the team to coordinate transition of the panels forming the moisture barrier with the fenestration systems and cladding.

The Architect, Exterior Envelope Consultant, and Building Envelope Commissioning Authority will present as a panel to offer insight into the design of the envelope and also methods used to verify installations in the field.

1.5 AIA CE LU/HSW

The session is a Case Study driven review of façade details for transparent systems. Where many education provide a review of the basic stock details the critical design issues often occur at the atypical conditions. The basic "rules of thumb" do not apply when the geometry or material choice require more from the design. This session will review the atypical conditions that do not occur in the idealized conditions. The course is crucial to those designing the enclosure of buildings that do not fit the mold of a common box. The case studies will include both transparent and opaque façade systems. Most importantly the discussion will include the junction of the transparent and opaque assemblies, where most facade failures occur. Important topics will include continuous insulation, mitigation of thermal bridges, condensation, waterproofing and structure.
