Work locations are 3788 78th Ave SE, 5472 W Mercer Way, 7036 W Mercer Way, and 7203 W Mercer Way. The contractor must maintain local access through designated blocks at all times during construction and may not perform major work on federal holidays or times prohibited under the right-of-way use permit. Substantial Completion is required within 130 working days from the Notice to Proceed, with Final Completion 10 calendar days thereafter.

The engineers' estimated project cost is $2.6 million. The contract is subject to Washington State prevailing wage requirements for King County, effective September 14, 2026. A bid deposit equal to at least 5% of the total bid price must accompany each bid. Bidders must be registered contractors with current Washington Unified Business Identifier numbers and comply with all applicable state and federal labor, safety, environmental, and nondiscrimination requirements, including Title VI. The City encourages participation of certified disadvantaged business enterprises and women business enterprises as prime contractors and subcontractors.

The non-mandatory pre-bid meeting is scheduled for August 31, 2026 at 9:00 a.m. at 3788 37th Ave SE. The City Council award is tentatively scheduled for October 6, 2026, with Notice to Proceed anticipated for the week of October 27, 2026.
