Vendor questions must be submitted by email by 8/20/2026, with answers provided via amendment on SAM.gov on 8/24/2026. The procurement uses a cascading set-aside approach, evaluating SDVOSB first, then VOSB, then other small businesses if adequate competition isn't received. Vendors must be actively registered in SAM.gov, and SDVOSBs must have the NAICS code on their profile and be certified by the SBA by the time bids are due. Quotes must be complete and address all requirements; commonly missed evaluation factors include three recent similar tree project references, a Certified Arborist resume with three years supervisory experience, and ISA certification. No site visit is scheduled; photos of the trees are available in the attachments on SAM.gov.
