27.1.CN.03 Constraints Map_Final.pdf

This is a Constraints Map document prepared by the Oregon Department of Transportation (ODOT) for the Hillsboro/Beaverton OR8/OR10 ADA Ramps project. The map identifies physical and environmental constraints affecting the proposed ADA ramp installations along the OR8 and OR10 corridors in the Hillsboro/Beaverton area. The document outlines the geographic scope of the project, marking locations where accessibility improvements are needed to comply with Americans with Disabilities Act requirements. The constraints map serves as a planning tool for Architecture and Engineering (A&E) service providers responding to ODOT's request for proposals from eligible Tier B Price Agreement holders, establishing the baseline conditions and limitations that will inform design and construction recommendations.

The constraints identified on the map provide critical context for service providers developing scope of work proposals and cost estimates for the ADA ramp improvements. The document depicts existing infrastructure conditions, right-of-way limitations, topographical challenges, utility locations, and other site-specific factors that will impact design feasibility and construction methodology. This information is essential for qualified consultants to accurately assess project complexity, develop appropriate engineering solutions, and prepare realistic proposals under the sample Work Order Component included as Attachment C in the solicitation materials.
