About this file
This is a technical drawing specification document for the Portland International Airport, a facility under Oregon's jurisdiction, detailing expansion joint replacement work for the Terminal Upper Roadway. The project, identified as PDX 2026-514, focuses on seismic joint repair at the approach ramp (Joint 35), with specifications for joint material removal, concrete surface preparation, and installation of new expansion joint assemblies. The drawing provides detailed construction requirements including concrete scanning procedures to locate and protect existing reinforcing, notching and sawcutting specifications, and anchoring methods using Hilti HIS-N 5" threaded insert anchors spaced at 18 inches on center with epoxy doweling into concrete. The scope includes cover plate fabrication in lengths between 4 and 6 feet, application of bonding agents, installation of welded wire mesh, and final sealing with Emseal Wabocrete product and stainless steel cover plates secured with countersunk machine bolts.
The technical specifications emphasize protective measures during construction, requiring contractors to scan existing slabs prior to drilling and cutting to avoid damage to reinforcing steel, with a minimum 2.5 inches of pour-back clearance and non-shrink grout application. The document, dated October 2026 and prepared by design and engineering professionals at the listed Portland address, establishes the standard for bid specifications and construction documentation. No pricing terms, set-aside provisions, incumbent contractor information, funding sources, or contract award details are provided in this technical drawing document; it serves solely as the engineering and design reference for the joint replacement project scope.
