Exhibit 6 - Plans.pdf

This file consists of engineering design drawings for a Steel Bridge Ramp project on Interstate 5 near the Naito Parkway in Portland, Oregon, prepared by the Oregon Department of Transportation (ODOT) and David Evans and Associates, Inc. The project involves the structural strengthening and girder reinforcement of an existing steel bridge on an on-ramp, with detailed plans including traffic control detour routing, internal shear anchor specifications, and construction sequencing. The drawings are dated December 12, 2025, with renewals noted through June 30, 2026, and include multiple sheets showing plan views, elevations, internal shear details, and girder strengthening details at various scales.

The construction notes specify that all materials and work must be performed according to the Oregon Standard Specifications for Construction 2020 and the 2024 edition of the Oregon Bridge Design Manual. Design of strengthening modules includes live load specifications from ODOT OP-40-D, OP-15-A, and EV-3. The work requires installation of internal shear anchors (SAX) for shear strengthening at spans, with reinforcing steel meeting ASTM A706 Grade 80 specifications. The project includes epoxy injection of cracks as required, with work items numbered and referenced on the design plans. The structure number is 02733C, with a structure ID of 113265, and work is designed for the Highway 101 West Naito Parkway location in Portland, Oregon. The project includes provisions for internal shear anchor reinforcement at multiple girder lines and locations as depicted in the structural sections and elevation details provided.
