Description: Works of renovation, adaptation and expansion of the IlhaMuseu, in Ilhabela, São Paulo, Brazil.

Deadline for Submission of Sealed Tenders: August 28, 2026

Posting Date: July 17, 2026

United Nations Educational, Science and Cultural Organization (UNESCO) hereby invite qualified companies to submit sealed tenders as follows:

Execution of services of renovation works and expansion and of new constructions of the project IlhaMuseu on Ilha das Cabras, located in Ilhabela, in São Paulo, as the projects of architecture and engineering.

The project aims to balance two fundamental aspects: reusing as much as possible the buildings, infrastructures and construction materials present on the island, considering the difficulty and cost of transporting materials both to the island and within it. The proposal provides for the renovation of existing buildings to adapt them to the new museum use, reducing the amount of material that would have to be transported to the island. With a focus on sustainability, accessibility, and integration with the natural environment. The island's rugged topography, with significant unevenness, poses an additional challenge for accessibility. The project foresees the construction of an accessibility system that includes suspended wooden walkways, ramps, an inclined plane elevator that follows the topography of the terrain and a vertical accessibility platform. Among the main buildings on the island are a pier, a jet-ski garage, stone-paved trails, a viewpoint, three houses and a swimming pool built directly on the rocky coast.

The purpose of this notice is to provide general information on the requirements for the procurement process and to inform interested suppliers how to obtain a copy of the Solicitation Documents.
