Key Facts

The protest.Subcontractors called a machinery convoy for Thursday 20 August 2026, outside the Concepción municipality and the regional Serviu offices.
Who is protesting.Subcontractors and suppliers of the Spanish construction firm Tapusa.
What was abandoned.The Esmeralda overpass and Eje Colón works in Concepción, the Perales interchange in Talcahuano and a municipal pavement contract. Minvu terminated the contracts on 5 May.
How many are affected.More than 50 contracting firms in the Biobío region.
How much is owed.Roughly CLP 3 billion (about US$3.3 million) across the region; one small firm, Ingeniería CMX, faces over CLP 600 million (about US$650,000) in factoring claims.
The official answer.Minvu and Serviu say responsibility lies with Tapusa and that the affected firms must go through the courts.

Heavy machinery shut O’Higgins avenue on Thursday. The people driving it are owed money by a company that left the country’s bridges half-built.

The Biobío contractors unpaid by Spanish builder Tapusa did what small firms do when nobody answers the phone: they called out the excavators. A machinery convoy was announced for Thursday 20 August, to gather in front of the Concepción municipality and the regional housing service, and the reason was money that has not arrived since April.

What Tapusa left behind

Tapusa walked away from work in the Gran Concepción area with jobs unfinished. The housing ministry terminated three Serviu Biobío contracts on 5 May: the Esmeralda overpass and a stretch of the Colón–Perales public transport corridor in Concepción, and the Perales interchange on the Concepción–Talcahuano motorway. A separate municipal pavement contract was also left unfinished.

Those are not marginal projects. Concepción and Talcahuano sit on either side of the Biobío river mouth, and the bridges between them carry a large share of the metropolitan area’s daily movement. An unfinished bridge is a visible, permanent reminder of a contractual failure.

Behind each of those contracts sat a chain of local subcontractors and suppliers — the firms that provided machinery, aggregates, formwork, labour and haulage. More than 50 of them in the region are now waiting to be paid. Housing minister Iván Poduje said at the time that the company had behaved like a delinquent and announced legal action across four regions.

How the money disappears

The mechanism is familiar to anyone who has worked in construction anywhere. A main contractor wins a public tender, subcontracts most of the physical work, receives progress payments from the state, and passes some of that money down the chain. When the main contractor stops, everything below it stops with it.

The regional total is put at around CLP 3 billion, roughly US$3.3 million. Individually the sums are small — these are family firms with a handful of machines — and that is exactly what makes them fatal. Ingeniería CMX, run by one of the affected owners, says it is facing more than CLP 600 million (about US$650,000) in factoring claims, meaning it sold its invoices to a finance company that now wants its money regardless of whether Tapusa ever pays.

Factoring is how small Chilean contractors survive the gap between doing work and being paid for it. It is also what turns a late payment into an existential one.

What the state says

The housing ministry and Serviu, its regional implementation arm, have been consistent. A ministerial memo issued by Poduje on 7 August states that where factoring credits are involved, Serviu must comply with what the courts decide and may not make payments or retentions outside those decisions. In plain terms: the debt is Tapusa’s, and the affected firms should sue.

Legally that position is defensible. Practically it asks small firms to fund a multi-year lawsuit against a foreign company that has already demonstrated it can leave. As Marcela Cuevas of Ingeniería CMX put it, going to trial means waiting three or four years, and they will not last that long.

This is the gap that Chilean subcontracting law has never closed. There is no general mechanism that lets the state pay down the chain when a main contractor collapses, and every few years a case like this makes the absence visible.

Why Biobío contractors unpaid is a bigger story than it looks

This is the second Spanish construction group to run into trouble in this region this month. In early August the finance ministry froze two Biobío public transport corridor concessions, on routes 160 and 150, worth about US$400 million — a separate case involving Azvi and a different set of projects.

The two are not connected, and it would be wrong to treat them as a single story. But together they raise a question that Chile’s infrastructure programme cannot avoid: whether the country’s tendering process is selecting for the lowest price rather than for the capacity to finish.

Chile has a very large pipeline of works ahead of it — the CBC counts US$87.7 billion of investment projects with defined schedules for 2026 to 2030, of which public works are just under a quarter. If small regional contractors conclude that working under an international main contractor carries an unmanageable risk of not being paid, the pipeline gets more expensive, not less.

What happens next

For the firms, the immediate path is judicial and slow. Some will not survive it. Chilean bankruptcy processes are not fast, and a factoring company holding an unpaid invoice does not wait.

For the region, the bridges remain unfinished until the contracts are re-tendered, which takes months at minimum and usually costs more the second time.

For anyone doing business in Chile, the practical lesson is the one the factoring companies already learned: check who is above you in the payment chain, not just who signed your contract. A public tender does not make the state your counterparty.

Frequently Asked Questions

Why have Biobío contractors gone unpaid?

The Spanish construction firm Tapusa abandoned works in the Gran Concepción area and the housing ministry terminated its contracts on 5 May 2026, leaving more than 50 regional subcontractors and suppliers owed roughly CLP 3 billion, about US$3.3 million.

Will the Chilean government pay the subcontractors?

The housing ministry and Serviu have said responsibility rests with Tapusa and that affected firms must pursue the debt through the courts. Direct payment from the ministry is not available.

Is this the same as the Biobío concessions story?

No. The freeze on the route 160 and 150 public transport corridor concessions involves Azvi and different projects, and was a finance ministry decision. The two cases are separate.
