Public-Private Partnerships - PPPs - are long-term contracts between a public authority and private parties to design, build, finance, operate or maintain public infrastructure and services. In La Plata, PPP projects are governed by a mix of legal rules: national PPP legislation and public procurement rules, provincial norms from Buenos Aires Province, and municipal ordinances and procedures enacted by the Municipalidad de La Plata. Typical PPP sectors include transport and roads, water and sanitation, solid waste, public buildings, urban regeneration and certain social infrastructure projects. Because PPPs commonly involve private financing and multi-year performance obligations, they require careful legal, technical and financial structuring to protect the public interest while delivering value.
PPPs are complex transactions that combine public law, contract law, procurement rules, administrative law, finance, land and environmental law, and labor regulation. You may need legal assistance in many common situations, including:
- Preparing or evaluating bid documents and tender offers to ensure compliance with procurement rules and bid requirements.
- Drafting, negotiating and reviewing concession or contract terms, including performance standards, payment mechanisms and termination clauses.
- Structuring project companies or special purpose vehicles - SPVs - and advising on corporate, tax and regulatory implications.
- Conducting legal due diligence on land titles, permits, liens, concession rights and third-party obligations.
- Securing and structuring project financing, including drafting security instruments and advising on guarantees and covenants.
- Obtaining necessary municipal and provincial approvals, land use and zoning permits, and environmental authorizations.
- Advising on risk allocation, force majeure, renegotiation procedures and potential conflicts with public policy goals.
- Representing clients in disputes, arbitration or administrative challenges arising from procurement or contract performance.
- Legal framework - National and local interplay: The national PPP framework provides a model and certain tools for PPPs, but provinces and municipalities adopt their own implementing rules. In La Plata, municipal ordinances and provincial procurement rules will often govern the award and execution of local PPPs.
- Procurement and tender procedures: Public tenders typically must follow competitive bidding rules, transparency requirements and public notice obligations. Bid evaluation criteria, prequalification rules and submission requirements are strictly enforced.
- Contract form and duration: PPPs are often structured as concession, lease or service contracts with detailed performance standards and long durations designed to allow cost recovery by the private party while protecting public interest.
- Risk allocation and payments: Contracts define who bears construction, availability, demand and financial risks. Payment mechanisms can include availability payments, user fees, shadow tolls or blended models combining public subsidies and private revenues.
- Financing and guarantees: Private financing requires enforceable security interests, guarantees and lender protections. Public entities may provide limited guarantees or payment commitments, but these often require specific budgetary authorizations and transparency.
- Permits, land and environment: Successful PPPs require alignment of municipal zoning, environmental impact evaluations and provincial permits. Delays or missing authorizations are common causes of disputes and renegotiation.
- Labor, social and local content requirements: Contracts may include obligations on hiring, social safeguards and local-sourcing rules that reflect municipal and provincial policy priorities.
- Dispute resolution and renegotiation: Many PPP contracts provide for stepped dispute resolution, including administrative negotiation, expert determination and arbitration provisions. National and provincial laws may influence enforceability of arbitration awards.
- Oversight and transparency: Municipal oversight bodies, audit offices and provincial regulators monitor PPP performance, budgets and potential renegotiations to ensure public accountability.
A PPP typically involves a long-term transfer of responsibilities to a private partner - often including design, construction, financing, operation and maintenance - with payment tied to performance or user revenues. Traditional public procurement usually covers discrete purchases or public works where the public sector retains responsibility for operation and financing.
Review the national PPP framework, applicable provincial regulations from Buenos Aires Province, and municipal ordinances and procurement rules from the Municipalidad de La Plata. Also consider environmental, zoning, labor and tax laws that affect project feasibility.
Bids are typically open to domestic and foreign private entities that meet prequalification criteria. Requirements may include financial capacity, technical experience, legal standing, and compliance with local registration or partnership rules. Joint ventures and SPVs are commonly used.
Projects are usually awarded through public tenders that set technical and financial requirements, evaluation criteria and contract terms. Evaluation can consider price, technical merit, experience and social impact. The process must comply with transparency and competition rules.
Key risks include permit delays, land disputes, construction cost overruns, demand shortfalls, currency and inflation exposure, changes in law or policy, and force majeure events. Contracts should allocate risks clearly and set mechanisms for mitigation, monitoring and compensation.
Some projects include limited municipal or provincial payment commitments, but public guarantees are subject to strict budgetary and legal constraints. Any guarantee or long-term payment obligation must be approved under applicable municipal and provincial fiscal rules.
Typical requirements include zoning and land use approvals, environmental impact assessments, construction permits, utility connections and specific sectoral licenses depending on the project - for example, water concessions may need additional sanitary authorizations.
PPPs commonly include multi-tier dispute resolution: negotiation, mediation or expert determination, followed by arbitration or judicial remedies. Many contracts favor arbitration for efficiency and finality, but enforceability depends on applicable law and public policy limits.
Renegotiation is possible but regulated. Contracts usually include procedures for changes in circumstances, extraordinary events and renegotiation triggers. Public transparency and compliance with procurement rules are essential when modifying contracts to avoid legal challenges.
Timelines vary widely. Preparing a PPP can take several months to a few years - including feasibility studies, procurement, financing and permitting. Implementation and operational phases extend over years or decades depending on the contract duration and complexity.
