# Roof replacement at four Gwinnett County schools

Gwinnett County Public Schools is seeking roof replacement work at Walnut Grove Elementary School, Central Gwinnett High School, Collins Hill High School and North Gwinnett High School. The canonical notice identifies the opportunity as a non-state agency procurement and lists an electronic bid as unavailable. It does not provide a project description, quantities, specifications, pricing basis or participation conditions. The exact portal’s Robots response was an invalid HTML service error, so no notice detail page was requested.

# Roof replacement at the Curitiba II campus

UNESPAR seeks an engineering or architecture company to replace the roofs of Blocks I and II and the cafeteria/patio at its Curitiba II campus. The PNCP notice lists an electronic pregão with open dispute mode and an estimated total of BRL 699,492.38. The proposal period is scheduled to open on 15 October 2026 at 08:00 and close on 30 October at 17:00, as listed without a timezone. The official API’s project location is Curitiba II, although the canonical issuer-location field says Paranavaí. The notice listing does not provide a work breakdown or award criteria.
