Construction companies in Chile

Section F, construction, holds 162,917 Chilean company records as of 2026-08-03, 161,509 of them active. By region, Metropolitana de Santiago leads with 73,761 (45% of the section), followed by Valparaíso (15,377) and Biobío (13,426). The largest divisions are 43 (specialized construction activities, 120,322) and 41 (construction of buildings, 22,471); one further division completes it. That is 4.8% of the Chile registry in this build.

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. In Chile, 100% of these rows carry an ISIC class; size is known for 41%; the registry publishes no website or e-mail; 14,842 were registered in the 12 months before the extraction. An economic activity is registered for about half of Chilean RUTs, so this section undercounts companies that never registered one with the SII.
