About this file
This is a construction drawings document prepared for the City of Milwaukie, Oregon, detailing design specifications for masonry and bollard improvements at Balfour Park. The project encompasses several key elements including chain link swing gates with dark green vinyl coated steel wire fabric, split rail fencing, post and cable fencing, decorative metal fencing, step stones constructed from Columbia River basalt, bollards with chain attachments, and boulder benches fabricated from wood slats and steel frames. The construction drawings contain detailed elevation views, sections, material specifications, and installation notes for each component. A mandatory pre-bid meeting is scheduled for 9:00 a.m. PDT on Thursday, June 4, 2026, at Balfour Park, located at 3039 SE Balfour Street, Milwaukie, Oregon 97222. Sealed bids are due by 2:00 p.m. PDT on Tuesday, June 23, 2026, with no public opening of bids. All work must be completed by November 30, 2026. The City is seeking qualified contractors to provide all labor, materials, machinery, tools, equipment, and other means necessary for project completion.
The solicitation utilizes a competitive sealed bid process for the purpose of selecting the bidder with the lowest cost. The project documents were prepared by Greenworks Landscape Architecture Environmental Design firm located in Portland, Oregon, and are the property of the City of Milwaukie, not to be reproduced without prior written permission. All materials specified include detailed notes requiring contractor shop drawing submissions for approval prior to installation, with specifications for materials such as dark green vinyl coated chain link, untreated cedar split rail fencing, Columbia River basalt step stones, and non-toxic preservatively treated Douglas fir wood slats. Specific hardware requirements, welding standards, and finishing specifications are detailed throughout the construction drawings to ensure quality and durability of all installed improvements.
