The project seeks professional engineering services for a structural vulnerability assessment of the existing Annex Building and a geotechnical investigation for a proposed new Annex Building and Irrigation System at the Ambassador’s residence in Bogotá, Colombia. Services include field investigations, laboratory analysis, structural diagnostics, and engineering designs for reinforcement, all in compliance with the Colombian Seismic Code (NSR-10). The Irrigation System features an underground tank and a ground-level control equipment facility, with structures classified as low-category requiring subsurface exploration. The government intends to award a contract to the lowest priced technically acceptable offer, potentially without discussions, and contractors must be registered in SAM. The solicitation will be officially published on SAM.gov and the U.S. Embassy Bogotá website.
