Construction companies in Antioquia, Colombia

Antioquia has 18,814 construction company records in ISIC section F (construction), 11,083 of them active, according to the RUES + Supersociedades (datos.gov.co) as of 2026-10-02. That is 12.2% of the section in Colombia and makes Antioquia the 2nd largest of 30 departments for construction. Its weight in the local economy is close to the national mix: 8.1% of Antioquia's records against 8.5% nationally (location quotient 0.96).

Colombian rows carry the department of the chamber of commerce; the registry publishes a municipality for under 3% of them, so there is no city breakdown for Colombia. The median active company is 5.0 years old; 12% were registered in the last year and 34% in the last three. In the 12 months to September 2026, 1,325 new construction businesses were registered in Antioquia, -2.4% on the previous 12 months (national section F: +5.3%). By ISIC division, 43 (specialized construction activities) is 37.9% of the records and 41 (construction of buildings) 32.3%. Size is known for 4% of the active companies; 18% of those are micro and 181 are medium or large.

One of the largest sections in every registry and the noisiest: developers register a company per project (SPE/SPV), so division 41 overstates the number of operating builders. Division 43 (specialised trades) is where the actual contractors are. Construction-tech, building-materials distributors, equipment rental and fintech lenders use this section with a size or age filter.
