Wood Utilization Grinding Services

The City and County of Denver Department of Parks and Recreation is seeking proposals for wood utilization grinding services through a competitive Request for Proposal (RFP) process. The procurement aims to secure a contractor capable of processing approximately 23,000 cubic yards of urban wood residue annually, collected through tree pruning and removal operations. Proposers must have a minimum of two years of experience handling landscape materials and will be responsible for tub grinding services, with estimated service requirements of one to two engagements per year, averaging 80 hours per engagement. The RFP requires detailed submissions including a Proposer Response Form, Price Sheet, Contract Certification Form, and Diversity & Inclusiveness Form. Key evaluation criteria will focus on qualifications, experience and capacity, billing rates, and diversity efforts. The proposal deadline is set for May 2, 2025, at 12:00 P.M. Mountain Time, with a virtual pre-proposal meeting scheduled for April 17, 2025, at 9:30 A.M. Mountain Time. Proposers must demonstrate capability to manage dust and noise levels and produce mulch meeting specific size and uniformity specifications.

The RFP does not explicitly indicate specific set-aside designations or restrictions for disadvantaged enterprises, though the Diversity & Inclusiveness Form suggests a preference for diverse and inclusive contractors. The City anticipates awarding a single contract with a maximum compensation of $450,000.00 over a three-year term, to be performed at the Office of the City Forester's Havana Nursery in Denver. Contractors must comply with prevailing wage requirements, with hourly rates determined by the 2025 Heavy General Wage Decision, which mandates minimum wages ranging from $18.81 to $55.25 per hour depending on trade classification. The contractor will be responsible for providing all necessary equipment, including tub grinders, wheel loaders, water trucks, skid steers, and service/fuel trucks. Insurance requirements and specific contract terms will be detailed in the sample contract, with the City retaining the right to cancel or suspend services. The pricing structure will include mobilization costs, fixed hourly equipment rates, and hourly labor costs, with careful consideration of the Prevailing Wage rates for Power Equipment Operator Group 3.
