The work covers the sector between kilometer DM 1,500.00 and DM 3,700.00 of route D-845, in the commune of Salamanca, province of Choapa, region of Coquimbo. The economic and administrative parameters of the call are:

• Financing: sectorial.
• Contract No.: 438927.

• 1 O.C. Earthworks.
• 3 O.C. Pavements, category 3rd B.

The terms and conditions are available exclusively on the portal www.mercadopublico.cl. The notice specifies that the sale of documentation or the delivery of physical terms does not apply, meaning the entire process is handled electronically.

Process calendar

The schedule set in the official publication establishes four consecutive milestones:

• Agency responses: until November 10, 2026.
• Closing of technical and economic bid reception: November 13, 2026, at 09:30 hours.

Interest for contractors and communities

With nearly 2,200 linear meters of intervention and a budget exceeding 725 million pesos, the call targets a narrow segment of the road works market, but one of high sensitivity for the inhabitants of the interior valley of Choapa. Route D-845 connects Salamanca with Zapallar, and its conservation affects the transport of agricultural cargo, access to basic services, and the daily connectivity of the rural communities in the area.

The requirement for a 3rd B category in pavements, combined with earthworks, restricts participation to contractors with registered experience with the MOP, which concentrates competition among a small group of regional and national companies capable of executing 240 days of continuous work. Interested parties have less than a week to submit inquiries to the agency, with the deadline expiring on November 4.
