OJCA Gym Roof Core Sampling
Solicitation # ojca-gym-roof-core-sampling

The project involves conducting moisture assessments and core sampling on two specific areas: a flat roof installed in 1994 and a hip area installed in 2003. The primary objective is to determine moisture levels in the existing insulation to evaluate if the roof is suitable for a coating over the existing membrane. Key deliverables include the removal and temporary waterproof patching of roof sections, photo documentation of strata, and comprehensive laboratory analysis of the findings. The solicitation is open to various small business set-asides, including SBA certified, women-owned, HUBZone, and veteran-owned businesses. Bids are due by 12:00pm on September 16, 2026. Award decisions will be based on the best overall value rather than the lowest price, with evaluation factors including pricing, technical approach, and New York State licensing. Required submissions include a completed bid sheet, a detailed cost breakdown, a W-9, and a vendor acknowledgement form. The winning contractor must maintain an active Sam.gov registration and a Unique Entity ID. Compliance requirements are stringent, mandating adherence to OSHA regulations, the National Electrical Code, NFPA Standard No. 101, and the Davis-Bacon Act. Depending on the final project value, performance and payment bonds may be required, specifically for projects exceeding 35,000 dollars. Final payment is contingent upon the submission of a signed punch list and applicable warranties. All inquiries and submissions are managed by Purchasing Agent Katie Curran.
