Construction tenders in Latin America and the Caribbean: where they are published and the rules behind them

States, provinces, municipalities and public works ministries often run procedures of their own on these systems, so search by buyer as well as by keyword.

Nearly every country keeps a register of suppliers and contractors, and a bid from a firm that is not on it, or whose registration has lapsed, is set aside. Foreign firms usually need apostilled or equivalent documents, so allow time.

The bid guarantee, the garantía de seriedad de la oferta, is set by law in several countries; check its amount, form and validity in the tender before you go to your bank.

Much of the region's infrastructure is financed by the Inter-American Development Bank and the World Bank and procured by the borrowing government under the lender's rules. Only firms and individuals from the IDB's member countries are eligible for IDB-financed procurement. As of October 2026 the IDB website refuses Bidligence's automated requests, so its notices reach you from the national portals and the nightly search; development-bank tenders explains how lender-funded procurement works.

The list below shows the multilateral sources that returned tender notices to Bidligence in the last 30 days.

Bidligence reads the national sources below for new notices on a schedule. A portal from the table above that is missing here is one Bidligence cannot read automatically today: Chile's Mercado Público and Jamaica's GOJEP build their tender lists in the browser, and Bidligence does not yet read Compras MX, Mexico's new platform.

New notices are matched against your watch profile (keywords, words to exclude, countries, regions, sources and a minimum value) and land in your opportunity inbox, with a daily or weekly digest e-mail. One click turns a notice into a bid, carrying the buyer, the deadline and the estimated value across; see tender alerts.

If a state, municipality or ministry you bid for is not listed, add its tender page or RSS feed to your workspace's sources. Bidligence then reads it daily, extracting the notices from a web page with AI, and matches them to your watch profile like any other source.

Some tenders appear only on state or municipal sites, or on portals that load in the browser. For the countries below, Bidligence also runs an AI web search for new tenders during the country's local night, once a workspace watches that country, and what it finds lands in the same inbox. It is a second net across 66 countries worldwide, not a promise to find every notice, so keep the official portals in your routine.

Brazil and Mexico are among Bidligence's 21 regional procurement profiles. Each sets the currency, the procurement rules, the typical buyers, the standards and the price sources that the analysis, the documents and the BOQ pricing work from: the Brazil profile brings in Lei 14.133 and the SINAPI and SICRO reference prices, which are mandatory ceilings, with ABNT standards; the Mexico profile brings in the public works law, lump-sum and unit-price contracts and the NOM and NMX standards. Tenders from other countries in the region use the global profile, which follows World Bank and FIDIC practice.

When you analyse a tender, Bidligence reads the bid security it asks for, the mandatory documents, and the closing date as it stands after every amendment you upload. The Bid Score rates the tender before you commit to pricing, and the Submission Guard checks each mandatory item against your Evidence Vault before you submit. The workspace can be read in Spanish or Portuguese, among other languages; the tender and the bid documents stay in the language the tender asks for.
