The Tribunal de Cuentas flagged a risk of collusion / price-fixing in seven 2021 Antel fiber-to-the-home tenders: awards to different suppliers with none objecting, and firms bidding while intending to form consortia with rivals.
The other side It is an alert and investigation, NOT proven collusion nor a sanction against any firm. The names are co-bidders in the same tenders.
In a 2006 UTE tender (Batlle plant lifespan), CSI Ingenieros —with Soluziona— billed US$2.8 M via add-ons exceeding 130% of the original contract. It was one of at least six UTE tenders (2006-2011) investigated for "rigged" contracts and over-billing.
The other side CSI Ingenieros denied wrongdoing and said it acted "by the book". It is a complaint and investigation, with no known conviction against the firm.
The Grupo Vía Central consortium (Saceem, Berkes, Spain's Sacyr and France's NGE) built the Central Railway for UPM under an MTOP PPP. The project ran up heavy cost overruns, questioned for lack of prior technical studies, and ended in crossed claims over over-prices and unpaid amounts.
The other side It is an overcost-and-payment dispute, not a criminal case. Both sides claim breaches by the other.
The consortium won OSE's Neptuno Project (a water plant in Arazatí drawing from the Río de la Plata) under a 20-year private-participation scheme. The Tribunal de Cuentas observed both the contract and its renegotiation for "substantially changing the object of the contract", breaching equality and competition.
The other side It is a legal-regularity observation on a highly politically and environmentally contested contract, not a criminal charge against the firms.
Alleged irregularities in the 2021 deal that extended to 2081 the exclusive container-terminal concession at the Port of Montevideo to Belgium's Katoen Natie. Senators charged that the ANP president approved the extension without the board.
The other side It is a concession, not a purchase: the flag is about the deal's regularity, not a supply contract. Competitors are pursuing international arbitration.
In the 2012 auction of state airline Pluna's seven planes, Cosmo (a "front" tied to Juan Carlos López Mena) bid backed by a Banco República guarantee granted in a "clearly and arbitrarily abusive" way. The Supreme Court called the guarantee "murky or less than transparent".
The other side The probe of the private parties (López Mena, Calvo Sánchez) was archived for lack of intent. The conviction falls on the officials who granted the guarantee, not on Cosmo.
