Tree Assessment

The City of Warren in Macomb County, Michigan, is seeking electronic bids for a comprehensive tree assessment of all trees within public right-of-way, parks, and public properties through Invitation to Bid (ITB-W-1535). The procurement requires a qualified consulting firm to perform a complete tree inventory using GPS equipment, collecting detailed information on each tree including location, species, size, condition, maintenance needs, and risk rating. Bidders must have specific qualifications, including at least five previous tree assessment projects, college-educated professional arborists with International Society of Arboriculture certification, and at least one team member with Tree Risk Assessment Qualification (TRAQ). The bid is due by 12:30 PM on May 7, 2025, with a public bid opening via Zoom at 1:00 PM EST on the same day. The selected vendor must complete the entire tree assessment within 180 calendar days of receiving the purchase order. Evaluation criteria will include the firm's experience, technical competence, reference list, capacity to perform work, past performance, and ability to deliver high-quality data in various formats. The City prefers a solution that integrates with ArcGIS and will provide supporting street maps, right-of-way information, and GIS data layers.

The procurement documents do not specify specific set-aside designations or restrictions for disadvantaged enterprises. The City reserves the right to award the bid based on the most advantageous proposal and emphasizes that the contract is not exclusive. While no incumbent vendors are explicitly mentioned, the project requires technological integration with existing ArcGIS infrastructure. The bid does not specify a precise budget range or award value, leaving flexibility for competitive proposals. The comprehensive nature of the tree assessment suggests a significant municipal investment in urban forestry management and infrastructure maintenance. Potential bidders will need to demonstrate substantial technical expertise, technological capabilities, and professional certifications to be considered competitive for this contract.
