In Portugal the execution of public works is governed by Decree-Law No. 18/2008, of 29 January 2008, which enacted the Public Contracts Code (Código dos Contratos Públicos), as amended. Construction works that are procured by private (non-public sector) entities are governed by the Civil Code, enacted by Decree-Law No. 47344, of 25 November 1966 (Código Civil), as amended.

In general any construction activity can only be undertaken by the contractor if he holds a contractor issued by the Institute for Public and Private Construction and Real Estate (IMPIC, IP) and in accordance with the type and the value of works that the relevant permit allows. This contractor, which is valid for an unlimited time, is issued in accordance with Law No. 41/2015, of 3 June 2015, as amended.
Some non-relevant works can be undertaken by the contractor if it holds a simple registration certificate issued electronically by IMPIC, IP, which is also valid for an unlimited time period.
Furthermore, in general terms, the construction of a building itself must be authorized by the municipality before the contractor can initiate any. The construction works.
As stated in the Legal Framework for Urbanization and Building (Regime Jurídico da Urbanização e Edificação), and taking into account the recent changes dictated by the Decree-Law No. 10/2024, of 8 January 2024, the starting of any construction activity (whereas a prior licensing procedure is applicable) is no longer dependent on the issuance of a construction permit, which is nowadays replaced by the receipt of payment of the legally required licensing fees.
The circumstances in which works carried out by the public sector do not need prior authorization have been increased by the Decree-Law No. 10/2024, of 8 January 2024. Amongst others, works carried out by the State, public institutes, universities, state enterprise sector for equipment and infrastructure regarding the State´s public housing do not require a prior authorization.

As part of the process of obtaining a licence, from the local authorities, for construction work to proceed, the developer may be required to fulfil certain conditions relating to the associated infrastructure that is required to support the development. For example, it is common for a developer to accept an obligation to build roads, electrical grids and other support infrastructures, in accordance with the specifications required by the local authority grantor of the construction permit or to transfer, to the municipality, part of its land and to build parking spaces, gardens and to provide areas for accessible housing or controlled costs housing.

Construction work procured by the public sector is governed by the Public Contracts Code. In general, the provisions of this code cannot be amended or excluded by the parties. In contracts for the design and construction of works procured by a private sector developer, the parties have greater freedom to agree their own terms and conditions. However, in a scenario where subcontracting is allowed by the Public Contracts Code, such contracts must clearly set out::
If the agreement fails to include this information, its terms will be deemed null and void. These contracts must also be kept on file for a ten-year period following completion of the works.

In relation to public works, the public sector is required to use a standard form contract which accords with the provisions of the Public Contracts Code. In relation to private works, the parties have to use a standard form contract which accords with the provisions of the Civil Code and, in addition, with the Public Contracts Code in relation to specific matters (eg price, additional works, etc). FIDIC forms are only used by major contractors or on international contracts.

The main parties are the employer and the contractor. The contractor may be responsible for both construction and engineering services (either directly or through a sub-contractor) or just for the construction. If the employer contracts the construction and the engineering services to the contractor, the latter will be the sole responsible towards the employer. On the other hand, if the engineering services are let directly by the employer, the contractor will have no contractual relationship with the engineering company and, therefore not be responsible for providing those services. The construction has to be carried out in accordance with the employer's specifications.

Normally, the contractor only assumes risks concerning the construction of the building (eg execution in accordance with the employer specifications, with the applicable regulations and without defects). It is, however, unusual for contractors to bear the financial risks that arise from the construction work or the cost of procuring licences.
Force majeure legal provisions will assist a contractor who is seeking a remedy for delay to or termination of works due to an unforeseen event that cannot be attributed to either party. It is also common (and advisable) for the parties to set out what sorts of events may qualify as force majeure and the contractual consequences of those events occurring.

Public-private partnerships (PPPs) are common in Portugal. They have been promoted and encouraged by the state for more than 20 years. According to the 2012 Report of the Treasury and Finance General Directorate, the public expense in PPP between 2008 and 2011 increased four times more. The main areas in which PPPs operate are transport infrastructures and health. Since 2011, there has been a slowdown of new PPPs. PPPs are governed by the Public Contracts Code and by the Decree-Law No. 111/2012, of 23 May 2012, as amended.

Yes, it is possible for parties to enter into a fixed price contract. However, parties often agree on the terms and conditions which allow the fixed price to be revised in certain circumstances. The Civil Code (applicable to all private works contracts) allows the employer to change the scope of the works, provided that its changes do not exceed one fifth of the total amount of the works and the associated costs are paid to the contractor. In public works contracts, payment of the fixed price is the rule; it is only if permitted by law and in very strict circumstances that the contractor will see the construction price revised.

The contractor is required to take out insurances (and present evidence of the same having been taken out by its sub-contractors) covering non-contractual liability arising from the construction activity as well as in respect of labour accidents (covering all hired personnel), 'automobile liability' (covering all the vehicles used in the construction of the works and those operating both on the site of the works as well as in adjacent public streets and areas) and equipment (covering all auxiliary means used in the works).
In addition, technicians responsible for the co-ordination and subscribing of projects as well as inspection of the works are required to enter into an insurance contract covering non-contractual liability. This insurance is intended to provide for proceeds which will cover any damage caused to third persons (outside the scope of the construction contract) by actions or negligent omissions. The insurance also covers liability for the actions and omissions of employees, lawyers and other persons involved in the activities of the insured or who provide services to the insured.

It is common for the employer to demand a guarantee of performance of the construction works and a guarantee that the works will be free from defects. These guarantees are usually given by the contractor by way of an independent 'first demand' bank guarantee (insurance bond contracts are also used) or deposit. The employer is granted a contractual right to withhold part of the construction price, for a specified period of time (to be agreed) as security against any construction defects that may arise during the specified period. In public contracts, works of less than EUR 200,000.00 in value do not require a guarantee, unless otherwise established in the tender rules. The usual amount of the guarantee is 5% of the construction price that the employer must pay to the contractor.

Contractors and sub-contractors are generally paid as they perform their obligations and carry out the works. To this end, construction milestones are agreed and payments are made if, and when, the milestones are met by the contractor. If the parties agree, a third party entity (typically a quantity surveyor) may be appointed to assess the works, for payment purposes. In public works contracts, payments according to construction milestones are the general rule. Each time part of the construction is completed, the parties calculate the value of the works carried out and a corresponding payment is made to the contractor.

The time frame within which the construction works have to be carried out and completed has to be specified in the construction contract. A delay in completion of the works may lead to the contractor having to pay contractual fines and possibly indemnities and, ultimately (the worst case scenario), to the contractor being replaced by another contractor or termination of the contract altogether. Completion of the works may, however, be delayed as a resulty of causes attributable to the employer, notably a delay in or lack of payment of the construction price or any instalment. In this case, the contractor may terminate the construction contract, request the overdue payments due to it and retain the building up to the date on which the employer meets its contractual obligations.

The Civil Code regulates private works contracts and, in relation to additional or complementary works, it states that the contractor may only perform such works with the consent of all involved parties and if the works are necessary for the completion of the original contract or if they result from unforeseeable circumstances. The contractor must notify the developer of the need for additional works and the parties must agree on the scope and the price of the additional works.
Regarding price adjustments, the Civil Code allows for price revisions if there are changes in the work scope or if the cost of labour and materials increases significantly beyond what was initially estimated. The parties may agree on the terms and conditions of price adjustments at the time of contracting. If no such agreement is reached, the developer must pay the contractor a fair price for the additional work. However, the price of the works cannot be increased in cases where the increase results from defects or omissions attributable to the contractor.
The Public Contracts Code in Portugal regulates the execution of additional or complementary works and states that they may be carried out under certain conditions, such as being necessary for the proper execution of the contract or resulting from unforeseeable circumstances. The contractor must submit a request for authorization to carry out such works, which will be evaluated by the developer.
In terms of price adjustments, the Public Contracts Code allows for variations in the initial contractual price under certain circumstances, such as changes in the scope of the work, unforeseeable circumstances or changes in applicable legislation. The developer may also agree to adjust the price if the contractor presents evidence of increased costs due to factors beyond their control. However, any price adjustments must be based on objective criteria and subject to the approval of the contracting entity.
Given the exceptional situation verified in the supply chains resulting from the global energy crisis, the COVID-19 disease pandemic and the war in Ukraine, and its consequential increases in the prices of raw materials, materials and labour, an extraordinary price review mechanism applicable to public works contracts was enacted which aims to adapt the form of price review that exists in the relevant contract to the actual and effective structure cost of the contract. This review mechanism is enshrined in the Decree-Law No. 36/2022, of 20 May 2022, and envisages accommodating the changes in the prices of materials, labour and equipment support (under the terms already defined in the Decree-Law No. 6/2004, of 6 January 2004).
This exceptional and temporary regime of extraordinary price revision depends on the contractor's initiative and was designed especially for public works contracts whose ordinary price revision is mandatory pursuant to the provisions of the article 382 of the Public Contracts Code. However, this regime applies also, with the necessary adaptations, to public contracts for the acquisition of goods and services.
In everything that is not expressly provided for in Decree-Law No. 36/2022, of 20 May 2022, are applicable the rules contained in the Decree-Law No. 6/2004, of 6 January 2004.

The construction must be performed in accordance with the applicable architectural and specialities projects and, as between the parties, with the terms of the relevant construction contract.
As far as pre-completion obligations are concerned, it is common for the employer to have the right to audit the construction works (either directly or through a third party) and, upon handover, to subject its acceptance to the removal of any construction defects. For contractual purposes, completion of the works is certified by both parties, directly or indirectly.

Under Portuguese law, the contractor is liable not just for breach of contract but also for unlawfully and wrongfully 'offending the rights of third parties' (such as purchasers, tenants and banks) or 'any legal provision meant to protect the interests of others'.
Breach of the construction contract leads to contractual liability; offending the rights of third parties may give rise to a non-contractual or tortious liability.
The contractor will only be liable if it acted with guilt and the burden of proof lies with the offended party, the claimant.

Yes. Construction contracts usually include arbitration clauses, particularly if foreign companies are involved. In Portugal, arbitration is considered to be more flexible than litigation through the courts. Arbitration is generally a quicker process than litigation, particularly as the parties are entitled to waive their rights of appeal. It is also a private process; this means that the parties are able to avoid disclosing trade secrets and to keep information confidential. The parties are also entitled to choose their arbitrators; appointed arbitrators are often lawyers with experience of matters such as those in dispute.

In Portugal, it is possible (but not mandatory) to refer construction disputes to ADR. The use of ADR as a method of dispute resolution is entirely dependent on agreement between the parties. ADR procedures include determination by an expert, mediation and conciliation. In Portugal it is not yet common for dispute to be referred to ADR.
