Naperville Park District is seeking sealed construction bids for the Nike Sports Complex Improvements, due at the Park District Administration Building by 11:00 a.m. on November 5, 2026. The work includes asphalt and concrete paving, synthetic turf, poured-in-place surfacing, playground and splash-pad equipment, fencing, a picnic shelter, shade sail, electrical and underdrainage work, landscaping, and lawn restoration. This is a construction solicitation, partly financed by an OSLAD grant rather than a grant opportunity; bid documents became available October 15, 2026, at 11:00 a.m., and a nonmandatory pre-bid meeting is scheduled for October 29, 2026, at 11:30 a.m.
