Construcción de plantilla de concreto con rampa frontal

Triple A S.A. E.S.P. is seeking technical information and referential pricing for the construction of a non-slip, washable concrete slab and front ramp located at Carrera 46 with Calle 6, at the entrance to the Bendición de Dios neighborhood in Colombia. The primary objective of this project is to create a stable surface to support two existing containers while ensuring that the sidewalk remains unobstructed and collection vehicles have a clear, continuous path without steps or protrusions. This solicitation is a sources-sought effort to estimate the budget for a future contract, with a response deadline of November 25, 2026. The scope of work includes technical visits, level surveys, area cleaning, excavation, and the installation of a 0.15 m compacted granular base and concrete slab. Key deliverables include validated construction proposals, material data sheets, and quality control records. Contractors must propose and justify the concrete strength, reinforcement, and soil improvement based on site visits. The project explicitly excludes the supply, transport, painting, or handling of the containers. Proposals must be submitted in COP and include detailed unit prices for labor, materials, and equipment, as well as the proposed execution period and time to put the site into service.
