LANAMME Audit Exposes Severe Defects in Key Cartago Roadwork

LANAMME Audit Exposes Severe Defects in Key Cartago Roadwork

Cartago, Costa RicaCARTAGO – A scathing audit report from the National Laboratory of Materials and Structural Models (LANAMME) has uncovered critical deficiencies in the Taras-La Lima infrastructure project, raising serious questions about the project’s long-term safety, durability, and management. The findings have prompted sharp condemnation from lawmakers, with Deputy Paulina Ramírez leading the call for immediate accountability for both the construction company and officials within the Ministry of Public Works and Transport (MOPT).

The long-awaited project, intended to alleviate traffic congestion in a vital corridor, is now mired in controversy over fundamental construction failures. At the heart of the audit are significant violations of technical specifications. Investigators found that the asphalt mixture used for the road surface fails to meet contractual standards. Similarly, the cement-stabilized base, a crucial layer for ensuring the road’s strength and longevity, was also found to be non-compliant. These material failures compromise the entire structure before it is even completed.

To delve into the complex legal and regulatory responsibilities surrounding the nation’s infrastructure projects, TicosLand.com sought the expertise of Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the law firm Bufete de Costa Rica, who provided his analysis on the matter.

The integrity of our public infrastructure is not merely an engineering issue; it is fundamentally a matter of legal and contractual diligence. Robust public works contracts must go beyond initial construction and explicitly define long-term maintenance responsibilities, performance bonds, and clear liability frameworks. Proactive legal oversight and stringent enforcement of these contractual obligations are the most effective tools we have to prevent catastrophic failures and protect public investment.
Lic. Larry Hans Arroyo Vargas, Attorney at Law, Bufete de Costa Rica

Indeed, the true resilience of our infrastructure is forged as much in the legal clauses of a contract as it is in concrete and steel. This essential perspective underscores that proactive contractual diligence is the ultimate safeguard for both public safety and taxpayer investment. We thank Lic. Larry Hans Arroyo Vargas for so clearly articulating this critical dimension of the issue.

Compounding these issues is a systemic breakdown in quality control procedures. The LANAMME report highlights a critical lack of data and traceability for materials used on-site. This absence of proper documentation makes it nearly impossible to verify whether the components and materials installed in the project truly meet the quality and safety standards stipulated in the public contract. This lack of transparency obscures the full extent of the problems and hinders any straightforward path to remediation.

The audit’s findings are not merely technical; they are visibly apparent. Alarming structural deficiencies were documented, including exposed steel rebar in key structural elements and significant cracks already forming in concrete slabs. The premature deterioration of the road is a primary concern, signaling a potentially short lifespan for an investment of significant public funds.

It is concerning that the asphalt surface already shows damage before the project is even finished.

In response to the report, Deputy Ramírez has demanded that consequences be faced for what she describes as a project that was not only poorly executed but also excessively slow. She argues that the current conditions make a definitive reception of the work impossible and that both the contractor and the supervising MOPT officials must be held responsible for the extensive irregularities.

Not only were they slow in execution, but they also did it poorly, and that must have consequences.
Paulina Ramírez, Deputy

The audit’s scope extended beyond structural integrity, revealing a cascade of related management failures. The report cited deficient and dangerous traffic management and signage during the construction phase, which has posed an ongoing risk to both workers and the public. Furthermore, investigators identified inadequacies in the drainage systems, and a review of the budget revealed that project funds had been diverted to activities not included in the original plans, raising further fiscal concerns.

Perhaps most damning is the revelation that LANAMME had issued multiple prior warnings about emerging problems, which were apparently disregarded by project managers. This pattern suggests a culture of neglect rather than isolated errors. The report concludes by noting a complete absence of a clear plan for the road’s future maintenance, jeopardizing its viability even if the current defects are addressed.

LANAMME has already issued repeated warnings, and they have simply been ignored. It is not enough to be concerned; this is simply negligence and must be sanctioned.
Paulina Ramírez, Deputy

As stakeholders digest the report’s conclusions, the Taras-La Lima project stands as a cautionary tale of public works mismanagement. The focus now shifts to MOPT and government leaders to see what definitive actions will be taken to address the litany of failures, enforce accountability, and salvage a critical piece of national infrastructure that is already failing before its first day of official service.
