The Land Use Act (132/1999) and the Building Act (751/2023) are the primary pieces of legislation regulating construction, land use and planning in Finland.
Several subordinated regulations and decrees regulate in more detail – eg, the technical requirements of buildings.
These regulations are issued by the government and relevant ministries pursuant to the Land Use Act and the Building Act.
In addition, certain matters, such as energy efficiency and requirements for construction materials, are regulated in separate laws.
There is no law specifically governing construction contracts, but the Finnish Contract Act (228/1929) governs all types of contracts and is also applicable to construction agreements.
Use of standard contracts is not mandatory. However, they are generally widely applied throughout the contract chains in construction projects in Finland. Some of the terms are already dated and do not fully take some factors into account – eg, digitalisation. Currently, deviations from the standard agreements are agreed widely between different parties throughout the subcontracting chains to reflect – eg, division of design and project management responsibilities between the parties in different forms of construction projects.
Standard contracts include YSE 1998 General Conditions for Building Contracts, KSE 2013 General Conditions for Consulting and RYHT 2000 General Procurement and Delivery Terms for Construction Products. In larger and more complex construction projects and especially in the field of infrastructure, the FIDIC (International Federation of Consulting Engineers) terms may also be used.
YSE 1998
These conditions are widely used between employer/contractor and contractor/subcontractor for construction works contracts.
KSE 2013
These conditions are commonly used between client/consultant for design and consulting services.
RYHT 2000
These terms are widely used between buyer/supplier for construction materials procurement throughout the construction chain.
FIDIC: Employer/Contractor/Engineer
These terms are widely in use in the employer-contractor relationship. The type of FIDIC contract depends on the scope and risk allocation. Some of the most used terms are:
In Finland, the companies that act as an employer in a construction project are typically developer/constructor companies, or sometimes project companies or real estate companies established for the purpose of the project. A significant portion of the employers are also public organisations or entities.
It should be noted that in Finland the risk allocation and general rights and obligations depend heavily on the chosen type of construction project. Parties can agree freely on the division of responsibilities under the contract. However, the most common contract types are:
In Finland, companies that act as a contractor in a construction project are typically construction companies. Contractors are always responsible for the construction works and procurement of all related construction materials, but depending on the contract type, they may also have responsibilities for design and/or construction management. Usually, the employer arranges the finance for the project but sometimes, especially related to residential building projects, the contractor may also act as the developer of the project. In this case the contractor also arranges the finance. Usually, the contractor co-ordinates the subcontractors and side contractors, and reports to the employer.
Subcontractors are usually smaller companies specialised in a specific field of construction such as electricity, civil works, HVCA and earthmoving.
According to YSE 1998 conditions, the contractor needs to inform the employer of any subcontractors used in the project and the employer may refuse the use of a specific subcontractor for due cause. The contractor always carries total liability for the subcontractors’ work towards the employer.
The co-ordination obligation of subcontractors’ work on site is usually carried out by the contractor. However, the division of responsibilities between different subcontractors is set out in the project agreement documents.
In Finland, it is common that a specific real estate company is established for the construction project. The real estate company then acts as the employer of the project. Typically, investment management companies and funds act as financiers of the established real estate company, thereby indirectly financing the construction project. In addition, sometimes the construction company carries out the project based on so-called founder contracting, where the construction contractor acts as the property developer and the financing of the construction is at least partly covered by selling the building premises in parallel with the construction works.
Please also see 3.3 Design. The type of company chosen to act as designer in a construction project is largely determined by the type of construction project. The largest construction companies can provide all the services required for a construction contract, including building design, on a turnkey basis. However, in most cases, they use design and architecture offices as subcontractors, or the planning/design is procured separately. Architects are in charge of design and planning, and they work hand in hand with other designers such as structural, civil and HVAC engineers.
The responsibilities and relationships between the designer, the employer and the contractor vary entirely depending on the type of construction contract and the type of construction project.
KSE 2013 conditions are widely used in construction consultation and design agreements. These terms define the obligations and liabilities between the consultant and the client (usually contractor) and the basis for charging, as well as IPR issues. As for the IPR, the client may not utilise the materials delivered by the consultant for an object or purpose other than the one specified in the contract without the consultant’s consent, unless otherwise agreed. The client is, however, entitled to any invention created during research or development efforts in the course of the agreed assignment. The consultant is entitled to additional compensation if the client’s right to the invention proves to be substantially more valuable than the compensation paid to the consultant.
The scope of each party is defined in the main construction contract and other contract documents attached to the contract, which usually include, for example, the building contract programme, building contract requirements, protocol for the contract negotiations, the division of responsibilities table, invitation to tender by the employer, tender documents by the contractor, specifications, designs, safety rules and safety programme, etc.
YSE 1998 conditions stipulate a procedure to manage any changes to the agreed scope due to modifications in building plans occurring during the construction phase. These variations are divided into modification works and additional works. A modification work may be a change, increase or reduction of works, whereas the additional works are works that did not originally form part of the obligations agreed under the contract. The pricing of the variations to the agreed scope is usually agreed in the agreement – eg, by setting out a unit price list that will apply in case of any agreed change orders during the project.
As a main rule, the contractor is obliged to carry out any modification works requested by the employer. The only exception is when the requested modification would significantly alter the nature of the scope agreed in the building contract. On the other hand, the contractor is also entitled to increase the contract price in the event there is an increase to the agreed obligations due to a modification in the building plans. The contractor has an obligation to notify the employer of any modifications in advance and, as a general rule, no modification work may be commenced before the parties have agreed on the effects of the modification works on the project schedule and contract price. The parties shall also agree on the time-related costs due to the modification works in the change order in accordance with the agreed change management procedure.
The responsibilities related to the design process depend on the contract between the parties and the type of construction project. In Finland, parties may agree freely on the division of obligations and the allocation of risk. However, the responsibility for design is usually determined by choosing the type of construction project. In Finland, there are standard contract templates published by the Confederation of Finnish Construction Industries RT for different project types. These templates can be freely modified by the parties, but they form a base for the risk allocation, when used.
In a divided multi-party construction work project and all-in works contract, the liability for design lies with the employer. In design-build contracts and turnkey contracts, the contractor is the party responsible for the design, and in project management contracting the responsibilities can be agreed to be carried by either party.
The division of responsibilities regarding the construction process may be agreed in several ways, but usually after the design phase, the allocation of responsibilities is as follows.
Responsibilities of the Employer
The employer is responsible for, inter alia, the following:
Responsibilities of the Contractor
The contractor is responsible for all the work carried out by the contractor or any subcontractor within the agreed scope. The contractor shall further ensure that the construction works are performed in accordance with the agreement documents, such as designs and specifications, and that they meet the requirements of construction regulations and are of good professional practice and industry standard.
In addition, the contractor is responsible for the co-ordination of the works of different subcontractors on site and schedule planning and management during the whole project.
Further Obligations of the Contractor
Unless agreed otherwise, the following obligations concerning the work of the contractor also apply to every contractor and subcontractor:
In addition, there are other obligations to be met by the contractors, which are indicated in the contract documents.
The responsible party for ensuring the condition of the soil of the planned site is the owner or the possessor of the real estate – ie, the employer. By mandatory law, Finland has a principle according to which the party that has caused pollution shall bear the liability thereof. However, secondary liability lies with the owner of the property.
The employer shall carry out all the relevant surveys and studies related to, inter alia, pollution, underground obstacles and geotechnical conditions on the site and further provide any reports and findings as part of the tender request documentation.
The contractor has an obligation to review all the reports and findings related to the construction site and further inspect the site before commencing the works. In the event the contractor identifies a reason due to which carrying out the construction works according to the planning is not possible, the contractor has an obligation to notify the employer of the matter without delay.
During the construction phase, the contractor is usually responsible for ensuring that the construction site meets the regulatory requirements (eg, regarding safety) set out for construction projects. The building inspection authorities can close down the construction site in the event the site does not meet the regulatory requirements.
According to Finnish law, almost all construction projects require a building permit that is granted by the regional building supervision authority. Application for the permit must be filed before the construction commences and the process is typically carried out by the employer. The requirement for other permits depends largely on the location and type of the construction project.
Under YSE 1998 conditions, unless otherwise agreed, each contractor carries the obligation for obtaining the permits required for the works under their scope.
During the construction phase before the handover, it is the contractor who is responsible for maintenance of the works. This is due to the fact that it is the contractor who bears the risk of damage or loss related to the works and materials during the construction phase.
After the handover of the project, the maintenance obligation transfers to the employer. Also, in the event the employer takes part of the works into use before the handover, the maintenance obligation and the risk of loss or damage related to such part lie thereafter with the employer.
Other functions of the construction process, such as operation, transfer or finance, are typically not instructed by the employer to the contractor or other third parties, but there are exceptions in relation to specific project types.
When the construction works are completed and the works are ready for the handover, the contractor needs to first pre-inspect the quality of the work that it is under obligation to carry out, and correct any deficiencies and defects detected. After the contractor’s pre-inspection, the works can be inspected by both parties in the handover inspection.
Inspection of construction goods and building components must be carried out on site before they are taken into use, and continuously during the work. Operational inspections of systems and installations shall be carried out in the form of performance tests before taking into use or, at the latest, in connection with the handover inspection when the system is ready and functioning. The contractor shall bear the costs of customary tests of construction goods and building components and for ascertaining the quality of works.
Qualified supervisors appointed by the employer monitor and supervise the works continuously. The supervisors and the employer have a right to inspect the site and the works at any time and to carry out tests that they deem necessary. It is important to note that these inspections do not diminish the contractor’s liability and responsibility for the works.
Both the employer and the contractor have a right to request the handover inspection when the works are at a stage where any work still in progress can be completed before the handover inspection takes place.
Before the handover inspection, the contractor needs to pre-inspect the quality of its works and that the works meet the requirements stated in the contract, and in case any defects are detected, correct such deficiencies and defects before the actual handover inspection takes place.
In the handover inspection it is assessed whether the finished result of the construction works fulfils the criteria stated in the contract. Minor finishing works yet to be completed do not prevent the handover in the event they will not cause impediment or harm when the works are taken into use.
In the handover inspection the employer prepares a protocol, in which it is stated whether any agreed obligations have been left unfulfilled and if the works are approved for handover. In addition, the parties agree a schedule for the minor finishing works to be carried out.
After the handover of the works, the contractor has a liability for any defects for a guarantee period of two years unless otherwise specified in the contract. During this time, any detected deviation from the contract requirements must be repaired or replaced by the contractor. The contractor’s work covered by the guarantee also includes additional and modification work.
During the guarantee period, the contractor is obliged to repair all defects, which the contractor cannot establish to have occurred for reasons beyond its control, for example by showing that the defect is due to normal wear and tear, or caused by incorrect use or neglect of maintenance measures for which the employer is liable.
Defects that create impediments for using the works or cause danger or disrepair must be repaired or removed by the contractor without delay. If the contractor fails in carrying out the repairs, the employer shall be entitled to carry out the work at the expense of the contractor after the employer has given prior notice of this to the contractor in writing.
If the defect is such that its correction is not necessary for the use of the building, and the cost of the repair would be unreasonable, the contractor, instead of repair or replacement, is obliged to reimburse the loss in value to the employer.
To secure its rights, the employer shall notify the contractor within a reasonable time after the defects were discovered or should have been discovered. If the employer fails to notify the contractor within a reasonable time, it may lose its right to claim the rectification of defects.
Even after the two-year guarantee period, the contractor is liable for any defects that the employer could reasonably not have noticed during the handover inspection or during the guarantee period, and that are due to gross negligence, work left uncompleted or a material failure of the contractor’s quality assurance process. The contractor is released from this liability after ten years have elapsed from the handover inspection.
In Finland, the price may be agreed as a fixed price or as time- and material-based, or a combination of these two. The methods to establish the price can be agreed freely between the parties. However, the most common way to establish the price is to agree on a fixed price with a milestone payment plan.
The price usually includes all the construction materials and work necessary for carrying out the agreed scope. The scope, which needs to be covered by the price, is presented in the employer’s invitation to tender documents, based on which the contractor will calculate the price of its tender.
Finnish legislation, along with the commonly used YSE 1998 and RYHT 2000 standard terms in construction contracts, allow the contract price to be indexed. However, the application of such clauses has traditionally been relatively limited. In recent years, there has been a growing trend towards including indexation clauses, particularly in large-scale projects where the construction phase spans a longer period. Even so, the decision to include such clauses is made on a case-by-case basis, and a significant proportion of projects still operate on a fixed-price basis. If indexation is not explicitly agreed in the contract, general cost increases do not affect the price. Thus, if there is no indexation clause in the contract, the contractor alone bears the risk of rising costs and ultimately the profitability of the contract. On the other hand, the owner of a building project does not benefit from a fall in prices.
Under the principle of freedom of contract, the parties can agree on how to link the price to the index, but YSE gives an option where the agreed price is paid as usual and revised when the index point value is published. In most cases, the contract price is linked to the Building Cost Index published and revised monthly by Statistics Finland. The aforementioned templates (YSE and RYHT, for example), can be freely modified by the parties, but they form a base for the risk allocation when used. All in all, the parties are free to agree on risk allocation in the contract as they deem fit.
The parties can agree the payment term and the delayed interest rate in their agreement.
Unless agreed otherwise, the contractor may claim delayed interest stipulated under the Interest Act, if the employer does not fulfil its payment obligations within 14 days from a legitimate invoice.
In addition, the contractor has a right to terminate the agreement in the event of non-payment, provided that the contractor has notified the employer of the termination threat in writing and has given the employer a reasonable time to correct the non-payment. Instead of terminating the agreement, the contractor may also interrupt the works temporarily until the payment obligation is fulfilled.
It should be noted that the employer may have a withholding right related to the contract price not yet paid – eg, in the event of delay or defect on the contractor’s side.
The parties can agree on the invoicing in the construction agreement.
Unless otherwise agreed, the invoices must be paid when the invoice is presented to the employer and the corresponding work stage under the contract is found to be completed or the invoice has otherwise been accepted to be due for payment. If the contract does not include a payment schedule or other provision on the arrangements for payment, the employer must pay the contract price to the contractor in the form of instalments, where the part payment to be paid is in proportion to the works carried out.
The final instalment of the contract price must be paid on the date defined in the payment schedule. Unless defined otherwise in the payment schedule or the contract, the final instalment must be paid after the handover, but at the latest after the final settlement of the accounts is completed, or when the financial relationship of the contracting parties has otherwise been settled.
An increase in the contract price or, correspondingly, a reimbursement, on account of additional or modification work, must be paid to the contracting party once the modification or additional work is completed. In the case of fairly extensive modification or additional work, the parties may agree on paying the compensation in several instalments as the work progresses.
The employer prepares a high-level main schedule for the different phases of the construction project, which guides the more detailed planning of different project phases (design and planning phase, procurement phase and execution phase).
Unless otherwise agreed, the employer will also prepare the project/design schedule together with the contractor.
Unless otherwise agreed, the contractor is responsible for planning and scheduling the works under its scope. The main contractor is also responsible for preparing the site construction schedule and co-ordinating the works together with the other contractors and the employer. The approved construction schedule will be followed by all the parties to the project and, except for minor refinements, changing the schedule shall be agreed jointly.
It is common that specific milestones with set dates are agreed between the parties and such milestones are also associated with delay penalties and milestone payments.
Both parties have an obligation to notify the other party without delay in the event a party becomes aware of an event or obstacle that could cause a delay to the construction project. A party shall notify the other party of the expected duration of the delay and the mitigation actions that the party is planning to carry out in order to prevent the delay.
A delay on the side of the employer may entitle the contractor to an extension, provided that the contractor has notified the employer of the grounds for the extension and the likely duration of the required extension in writing. In the event there are several reasons which would entitle the contractor to an extension simultaneously, the contract period can be extended only based on the combined effect of these reasons, and the contractor is not entitled to full extension for each reason separately. In the event the delay is due to the employer, the contractor has a right to claim the time-related costs due to the delay to the extent the contractor could not avoid the costs – eg, by re-organising the works on site.
According to YSE 1998 conditions, in the event of delays, the employer is entitled to claim a penalty. The penalty must be paid for each working day that the construction works remain uncompleted beyond the times agreed. The parties can agree the amount of the penalty as they wish, but YSE conditions state the penalties that will be applied unless otherwise agreed.
According to YSE conditions, the penalty for delay is 0.05% of the contract price exclusive of value added tax for each working day the works are delayed (0.1% in subcontracts). The penalty for delay shall be calculated for a maximum of 50 working days for the completion of the works, and a maximum of 75 working days if the milestones with set dates are included in the agreement. The employer is not entitled to any other compensation for the delay unless the contractor has acted wilfully or with gross negligence.
According to YSE 1998 conditions, the contractor is entitled to request, and thereby can be granted, an extension of time in the following circumstances:
To secure its rights to the extension, the contractor must, without delay notify the employer of the required extension and of the grounds for the extension, at the risk of otherwise forfeiting its right to the extension. The requirement and justification for the extension of time can be established, for example, by means of site journals (containing information on the progress, delays and changes of the contract) and other written evidence, but in most cases the justification for the extension requires a detailed analysis of the effects on the schedule. In addition to the YSE conditions, the parties may specify separate criteria for the extension of time in the building contract.
Force majeure is widely recognised as a contractual principle in Finnish case law. A force majeure event is generally an unforeseeable event beyond the parties’ control that could not have been reasonably avoided or overcome and that is not attributable to the other party. Force majeure may include events such as war, strike, natural catastrophes, pandemic, etc. It is possible to contractually limit or exclude certain circumstances from being qualified as force majeure.
Under YSE 1998 conditions, force majeure is defined as:
In case of force majeure, the contractor is entitled to suspend the works and receive an extension to the agreed completion time and milestones, but only part of the costs incurred by the contractor due to such suspension are covered by the employer.
The parties are entitled to terminate the contract if it is necessary to interrupt the construction works for a long and indefinite period on account of a force majeure event.
Unforeseen circumstances are not governed by mandatory or regulatory law. The subject is contractually agreed upon by the parties. Unforeseen circumstances may qualify as a force majeure event if the conditions mentioned in 5.5 Force Majeure are at hand.
According to YSE 1998 conditions, a contractor has the right to obtain a reasonable extension to the agreed schedule, if the employer causes a delay – eg, by not providing the necessary approvals in a timely manner. The same right also rests with the contractor when any other contractor or supplier contracted by the employer causes a delaying disruption at the site. However, to secure its right to the extension, the contractor must notify the employer of the required extension and of the grounds for the extension, at the risk of otherwise forfeiting its right to the extension. It is the obligation of the contractor to establish both the existence and the duration of the disruption and its causal connection to the required extension.
According to Finnish general legal principles and case law, damages caused by wilful misconduct and gross negligence cannot be contractually excluded. In addition, parties cannot exclude their liability based on the mandatory Product Liability Act, which is also applicable in the field of construction.
Wilful misconduct and gross negligence exist under Finnish law. The terms are defined in the Criminal Code and the concepts are also well established under contract law and form a firm principle of the type of liabilities, which cannot be contractually excluded. Based on the freedom of contract principle, parties can agree on limitations of liability under a contract, except to the extent a party has acted wilfully or with gross negligence.
Parties can agree contractually on limitations to their liability. However, in the construction field, extensive limitations to one’s liability are quite exceptional and limited in their content.
Under YSE 1998 conditions, there is only limitation regarding damage that could not have been avoided even if the party had acted with all due care. According to YSE conditions, a contracting party shall not be liable for any damage that it could not have avoided, even if it had taken all possible care.
Liability to a Third Party
The same principle also applies to the contractor’s liability to a third party.
Under YSE 1998 conditions, the contractor is liable for any loss, damage or harm caused to a third party and to the third party’s property during the construction works. The contractor is not, however, liable for loss, damage or harm that is an unavoidable consequence of the work that had to be carried out and that even by taking the utmost care, the contractor could not have avoided.
The contractor is nevertheless liable for any loss or damage irrespective of negligence for which the liability results from mandatory law, such as the Product Liability Act.
In construction projects in Finland, indemnity clauses are typically used only as regards to damage caused to third parties in relation to personal injury, death or damage to property.
Typically used guarantees under construction projects are the guarantee for the construction period and the guarantee for the warranty period, and, occasionally, the advance payment guarantee.
Under YSE 1998 conditions, the guarantee for the construction period is 10% and the guarantee for the warranty period is 2% of the construction price excluding VAT. A guarantee can be provided by a bank or other financial or insurance institution, or it can be a deposit of money in a financial institution. A parent company guarantee does not qualify for a guarantee unless the parties agree that such guarantee is sufficient. Generally, on-demand guarantees are not used in the construction industry, except in complex projects.
Providing guarantees can apply to both of the parties depending on what has been agreed, but it is typical that at least the contractor will provide the guarantees. In the event the parties agree that the employer shall provide a guarantee for its contractual obligations, the amount of guarantee is 10% of the contract price exclusive of VAT under YSE conditions.
According to the YSE 1998 conditions, the contractor is obliged at its own expense to take out insurance for the replacement value of the building project, construction products and working materials procured for the purposes of the works. However, the parties may agree to deviate from this main rule in the construction contract.
Insurances for a Construction Project
Unless otherwise agreed, the contractor responsible for site management duties is obliged, at its own expense, to take out insurance for the replacement value of the building project and construction products, and any working materials procured for the purposes of the works under the agreed scope.
The insurance must also cover any subcontracts, as well as procurement of goods and services by the employer and other insurance objects specified in the contract documents. If the project does not have a contractor responsible for site management duties, each contractor shall be responsible for insurance covering its own work.
The employer notifies the contractor of the estimated value of the nominated subcontracts, procurement by the employer and other objects of insurance in the invitation to tender.
If the value of an insurance object changes significantly, the insurance sum shall be adjusted in line with the value of the object. The corresponding change in the insurance premium must be covered or reimbursed to the contracting party.
The insurance shall be taken out as contractors’ all-risk insurance or other indemnity insurance that covers the insurance object for unforeseeable events such as loss due to a fire or malicious damage, including demolition and clearance costs. The insurance must remain in force until the entire insured building project is handed over, and it must also cover loss or damage arising from any work undertaken after the handover during the guarantee period. The general responsibility for the insurances after the handover lies with the employer/building owner.
Insurance must be taken out in the building owner’s name from a financially sound insurance company that engages in general insurance activity in the country in which the building project is located. The sum insured must at all times correspond to the full value of the insurance object, including any additional and modification work. Unless otherwise agreed, the deductible in the insurance may not exceed 0.5% of the contract price between the contractor and the employer.
The insurance policy or the certificate issued by the insurance company pertaining to the insurance that is in force must be provided to the employer before instalments payable on any work or procurement can be made.
Subcontractors are obliged to take insurances for the building project as separately agreed. In addition, all the contractors working on the site shall have valid business liability insurance.
Insurances for Repair Work
Unless otherwise agreed, the contractor’s insurance obligation in repair work of older structures is limited to the value of the repair. The building owner must notify the contractor of any valid buildings insurance and further notify the insurance company of the repair work.
Each contractor shall itself be responsible for insurance of its construction equipment and also for insurance of its construction products and working materials in repair work.
Under YSE 1998 conditions, both the employer and the contractor have the right to terminate the contract if the other party is declared bankrupt, or it is otherwise deemed likely that the party is unable to fulfil its contractual obligations.
In the event it is deemed likely that the party is unable to fulfil its contractual obligation due to insolvency, the party may avoid the termination by providing a sufficient surety to secure the performance of its obligations.
In Finland, the parties are free to agree on risk allocation in the contract as they deem fit. Using model agreement templates that are fit for certain types of construction project, and general terms such as YSE 1998 conditions, risk is allocated based on the chosen agreement model and construction project type. There are no general principles for pricing of shared risks in Finland although the standard contract templates (published by the Confederation of Finnish Construction Industries RT) form a base for the risk allocation between the parties. The pricing of shared risks depends on the type of construction project and contract and what has been agreed between the parties.
Project alliance is a relatively popular project delivery model in Finland. In this delivery method the parties assume joint responsibility for the design and construction of the project. The joint responsibility is realised through a joint project management organisation and a contract according to which the parties share both positive and negative risks related to the project.
Under YSE 1998 conditions, there are a number of obligations directed to the contractor regarding personnel working on the construction project.
First, the contractor must have a sufficient number of skilled employees to carry out the building contract works. The contractor is obliged to provide the employer with information concerning the number of persons working on site and all persons must have an individual identifier when on site.
Management Obligations of the Contractor
The contractor responsible for site management duties must have a foreman in charge of the building site who manages the building work and is responsible for ensuring that the work is carried out in accordance with the Building Act, the Building Decree and the building regulations.
Each contractor must operate with management that is sufficient and competent for the demands of the building contract works and must appoint a person in charge of the work for the full period of the construction. The employer must be able to contact the contractor’s representative, and the representative must always be available on site as required.
Health and Safety at the Site
The contractor responsible for site management duties must appoint a person responsible, for example, for ensuring that the general management on the site is sufficient from a health and safety perspective.
In addition, each subcontractor must appoint a competent and accountable person for the management and supervision of its work, who shall be responsible for observing the rules concerning health and safety at the site.
If a person employed by the contractor proves incompetent or unsuitable to the extent that the work performance suffers and the matter is not rectified after a written notice from the employer, the person must be replaced with another more competent person.
In addition to the YSE conditions, in Finland there is the mandatory Act on the Contractor’s Obligations and Liability when Work is Contracted Out, which also needs to be complied with in construction projects. The purpose of the act is to promote fair competition between companies, as well as compliance with terms of employment on the labour market.
Before concluding the agreement, the contractor must ensure that its subcontractors comply with their statutory obligations. Compliance with obligations is verified by providing the information listed in the Act on the Contractor’s Obligations and Liability when Work is Contracted Out:
Each contractor is responsible for obtaining these reports and documents from their subcontractors.
Subcontracting is widely used in the Finnish construction industry and thus all Finland’s general terms and industry standards acknowledge the use of subcontractors.
YSE 1998 Conditions
Subcontracting is allowed under YSE conditions. However, the contractor must obtain an approval from the employer for the main subcontractors. The leverage of the employer when choosing the subcontractors is, however, limited, since the employer can refuse to approve the subcontractor only with due cause.
The due cause can exist – eg, due to the subcontractor’s failure to fully comply with the provisions on quality assurance, or neglect in payment of taxes or employer’s contributions.
The contractor shall assume responsibility for any works carried out by the subcontractors and further ensure that duties performed by the subcontractors are carried out in accordance with the time schedule.
KSE 2013 (Construction Consultation, Design)
According to the KSE 2013, the consultant is not entitled to use another consultant as a subconsultant while performing its duties without the client’s consent. The client’s consent is not required when subcontracting routine or minor tasks under the consultation agreement.
If subconsultants are used, the consultant shall inform the client of this. The consultant is liable for the subconsultant’s work as if it were its own.
As for intellectual property rights, YSE 1998 conditions only govern copyright. According to YSE conditions, the basic principle is that each contracting party shall retain the copyright for their own drawings and other planning documents. Using the other party’s planning documents in other projects is prohibited without the party’s permission.
Also, according to KSE 2013 conditions, which are widely used in construction consultation and design agreements, the client may not utilise the materials delivered by the consultant for another object or purpose than the one specified in the contract without the consultant’s consent.
Under KSE 2013 conditions the client is, however, entitled to any invention created during research or development efforts in the course of the agreed assignment. The consultant is entitled to additional compensation if the client’s right to the invention proves to be substantially more valuable than the compensation paid to the consultant. Miniature models and other illustrative materials paid for by the client are considered to be the property of the client.
There are several remedies governed under YSE 1998 conditions in the event of breach of contract. The remedy available depends on the type and severity of the breach.
Contractor’s Breach of the Agreement
If the contractor neglects to fulfil one of its obligations under the contract, and the contractor fails to rectify the situation within a reasonable time limit after receiving a written notification from the employer of the breach, the employer is entitled to fulfil the obligation at the expense of the contractor.
The employer may claim the expenses related to the neglect from the contractor either by setting off an equivalent amount of the contract price as being paid, or by debiting the expenses separately from the contractor.
Employer’s Breach of the Agreement
If the employer fails to pay for the works on time or if the employer otherwise breaches its obligation under the contract, the contractor may claim the costs for the breach from the employer and suspend the works, provided that the contractor has notified the employer of the breach in writing and the employer has not corrected the neglect within a reasonable time.
Termination of the Agreement
Both contractor’s and employer’s material breach of the contract may lead to a situation where the other party is entitled to terminate the contract as a remedy. YSE conditions include detailed provisions concerning situations where the termination of the contract can be used. The contractor is also entitled to temporarily interrupt the work as a remedy instead of termination of the contract.
Before the contract is terminated, the party must draw the other party’s attention to the termination threat by notifying the other party in writing of the threat to terminate the contract, unless the neglect is corrected within a reasonable time.
In Finland, it is not very common to contractually limit the remedies available to a party under the general conditions of YSE 1998. However, as the general conditions are relatively old and do not always provide sufficient protection for the parties’ rights in today’s projects, it would be recommended to carefully assess whether any modifications to the YSE 1998 conditions would be necessary and especially consider whether the allocation of risk and remedies available are sufficient.
Sole remedy clauses are not typical in construction contracts in Finland.
In relation to delay, the employer’s options for remedy are usually limited to claiming liquidated damages (delay penalty). In the event of delay, the employer may not seek any other damages except the agreed delay penalty, and this could be seen as a sort of a sole remedy clause. However, if the delay is due to wilful misconduct or gross negligence, the liability of the contractor is not limited solely to the delay penalty, but the employer can also claim damages caused due to the delay.
Unless the parties have agreed otherwise in the construction contract, there are no limitations on the type of damages that a party is obliged to compensate due to a breach of the agreement. As a general rule, the parties are entitled to the full compensation with no maximum cap in the event of contract breach, unless otherwise stated in the construction contract. A contracting party is not, however, liable for loss or damage that it could not have avoided even by taking the utmost care.
However, as explained in 5.3 Remedies in the Event of Delays, the contractor’s liability for delay is limited to the obligation to pay a delay penalty unless the delay is caused wilfully or by gross negligence.
As mentioned in 5.5 Force Majeure, under YSE 1998 conditions the contractor has the right to temporarily interrupt the work until it can be seen whether the force majeure event will inevitably lead to termination of the contract. In such cases the contractor must provide a written notice to the employer stating the cause for the interruption.
The contractor is entitled to suspend the contract works temporarily if the employer does not fulfil its payment obligation or any other obligations that materially affect the execution of the building contract, or if the employer, through its actions, prevents completion of the construction works in accordance with the contract.
The contractor is also entitled to suspend the works if the employer is deemed to be in a situation where it cannot be expected to appropriately fulfil its contractual obligations. The employer can avoid the suspension by providing a reliable additional surety or a report of the fulfilment of the obligations within one week of the contractor’s written notification of the suspension.
As for the employer, it is a common remedy for employers to withhold a payment or set off a claim from the agreed payments in the event the employer has a claim against the contractor due to a contract breach such as delay.
YSE 1998 conditions include detailed provisions concerning situations where the termination of the contract for cause can be applied.
According to YSE conditions, the employer has the right to terminate the contract if, inter alia, the contractor does not commence the works in the agreed schedule or the works are being carried out so slowly that it is apparent that the works cannot be completed in the agreed time, except if this is due to reasons that would entitle the contractor to an extension. In addition, the employer may terminate the agreement in the event the contractor has not provided the agreed guarantee to the employer in time.
The contractor has the right to terminate the contract if, inter alia, the employer does not fulfil its payment obligation, or other obligation substantially affecting the performance of the contract.
The termination is only possible in the event the party in breach has not remedied the situation within reasonable time after receiving a written termination notification from the other party.
In the event the contract is terminated for cause, the breaching party shall compensate all the damages and costs due to the termination to the other party in full.
If nothing else is agreed in the construction contract between the parties, the respective district court is competent to adjudicate disputes related to construction contracts.
It is possible and fairly common for the contracting parties to agree on alternative dispute resolution means in the construction contract.
Arbitration is commonly used in the larger construction project contracts and the YSE 1998 conditions also include provisions concerning arbitration. If arbitration is used as a dispute resolution method, it is typical to agree on the arbitration procedure in accordance with the Rules of the Arbitration Institute of the Finnish Chambers of Commerce. The arbitration procedure is governed by the Finnish Arbitration Act.
In addition, the parties may agree on dispute resolution by means of mediation, and different kinds of mediation clauses have become increasingly popular in construction contracts, partly due to the high costs related to other dispute resolution alternatives.

The Finnish construction market is gradually recovering from a long downswing. The obstacles related to lack of new housing starts, tighter financing conditions and rising material costs have not been completely overcome, but the market is also giving signs of cautious optimism for 2025 and beyond. Residential construction activities are still far below their peak, while other segments such as infrastructure and industrial facilities as well as public projects are still moving forward. The renovation market, especially for improving energy efficiency, is also expected to be strong. At the same time, sustainability and digitalisation continue to play a central role, reshaping the way construction projects are planned and delivered across Finland. In 2025, the adoption of technological advancements such as building information modelling (BIM), automation and AI in project management and design processes, as well as smart building technologies, is anticipated to increase significantly within the Finnish construction sector.
One significant ongoing reform is the revision of the general industry conditions in the construction sector, the YSE 1998 conditions. The renewal negotiations are being conducted by the industry associations Finnish Property Owners Rakli and the Confederation of Finnish Construction Industries RT (CFCI). The revision examines the effects of changes in the operating environment and the needs for change identified jointly by the parties. Negotiations address, inter alia, conditions related to change orders as well as conditions concerning co-operation between the parties. The local industry standard conditions are almost 30 years old, and although they have stood the test of time, there are several drivers that address the need for “YSE 1998 2.0”. One of the drivers is the fact that many stakeholders in the field, especially in more complex projects, already supplement or deviate from YSE 1998 conditions in the construction contracts to address more modern forms of risk-sharing. In addition, over the decades a vast Finnish case law has evolved around YSE conditions and many practitioners in the field believe that a new version could incorporate clarifications on the practices established by the courts.
Recent Case Law
The Supreme Court of Finland has recently issued some important preliminary rulings on construction law.
The first decision concerns the contractor’s ten-year liability after the end of the warranty period. According to Clause 30 of the widely used YSE 1998 conditions, the contractor is liable even after the warranty period for defects which the client proves to have been caused by the contractor’s gross negligence, non-performance or substantial non-compliance with the agreed quality assurance and which the client could not reasonably have discovered during the construction period or the warranty period.
The contractor’s liability under this clause has been the subject of much debate. On 9 January 2025, the Supreme Court issued a preliminary ruling, KKO 2025:3, on the question of whether a defect in the contractor’s performance was caused by gross negligence. The contractor had replaced the water pipes in an apartment block with dozens of flats. A very large number of these pipes were found to have material sealing defects after the warranty period had expired. The Supreme Court held that the contractor’s defect had been caused by its gross negligence and that the contractor was therefore liable for its defect after the warranty period. The decision will help to clarify the interpretation of post-warranty liability in the future.
On 3 October 2024, the Supreme Court issued a preliminary ruling, KKO 2024:56, concerning penalties and damages in the event of delay by the main contractor. In this case, the main contractor, contrary to the agreement between the parties, handed over the work areas to the subcontractor delayed. The subcontractor claimed damages in excess of the agreed penalties. The Supreme Court held that the consequences of the delay were determined by the penalty and limitation clauses and that the subcontractor was not entitled to the damages it claimed in excess of the penalty. The decision clarifies the current legal status as to when damages in excess of the contractual penalty can be claimed for delay.
The Supreme Court has also granted leave to appeal in KKO VL 2024:58, a case concerning the distinction between liability based on the construction period and the warranty period. The case is pending.
The case concerns the defects in the flooded floor drain, which were recorded in the handover inspection report and agreed to be repaired. However, later during the warranty period, it was discovered that the flooding had been caused by faulty installation of the drainage system, which the contractor had failed to correct.
The question in the case is whether the defect is based on the contractor’s breach of his obligations during the works or under the warranty and whether the company that had given a guarantee to the client for the warranty on behalf of the contractor is liable for the damage caused by the repair of the defect. This is a relevant and topical issue given the poor economic climate in the construction sector, which has led to a large number of disputes relating specifically to the liability of guarantors.
Permitting Initiatives
Finland has in recent years seen an upswing in legislative initiatives which aim at eliminating bottlenecks in permitting, especially with respect to green transition projects. Part of these initiatives are motivated by EU legislation, while others are purely based on national regulation.
Siting permit for clean transition projects
The new Building Act entered into force on 1 January 2025. The new Act streamlines the permitting structure for all construction projects and, In addition, introduces a new type of siting permit for clean transition projects.
The siting permit intends to accelerate the planning phase of certain clean transition projects and applies to the following types of construction projects:
The Finnish land use planning system is built on a hierarchy of planning instruments, and preparing or amending a land use plan that enables the construction of an industrial project typically takes two to five years. As of January 2026, siting permits for the above projects must be handled within six months. The new siting permit for clean transition projects allows for the development and permitting of the project types falling into the above scope without a separate time-consuming land use planning process. However, impact surveys (eg, nature impact surveys) need to be prepared to the same extent as for a land use plan.
While a large number of wind and solar power projects are being planned in Finland, these technologies have been excluded from the scope of the siting permit for clean transition projects. These exceptions are a result of political debate. Instead, the Finnish government is preparing amendments to the Finnish Land Use Act, with the intent to introduce a specific land use plan type for solar power, similar to the current land use plan specifically for wind power. The preparation of the amendments to the Land Use Act has been delayed, resulting in unclarities and local variance with respect to land use planning and permitting requirements for industrial-scale solar power.
Accelerated permit processes for prioritised projects
The current legislation includes an obligation for permit authorities and administrative appeal courts to handle, for a fixed period of time, certain permit matters and related appeals with priority. The priority has been given to permits for renewable energy projects and certain other green transition projects. This legislation will likely be extended by a few years until 2030 (for appeals until 2032), and also cover in the future data centres and projects that fall under the EU’s Net-Zero Industry Act and the European Critical Raw Materials Act. A maximum handling time of 12 months is also being introduced to these priority permit applications. The final proposal is being prepared, and the changes are intended to take effect on 1 January 2026.
In addition, the Finnish government is preparing legislative changes aiming at updating the legal maximum timeframes for permitting renewable energy projects as required by the RED III Directive. The final proposal is being prepared, and the changes are intended to take effect as soon as possible.
Developing the one-stop shop principle for environmental permits
The Finnish government is preparing a reform of the environmental permitting authority organisation, which also includes an initiative to develop the one-stop shop principle applicable to environmental permitting.
To date, the permitting and supervision of environmental-related permits have been separated into two national authorities, namely the Regional State Administrative Agency responsible for environmental permitting of most large-scale projects, and the regional Centres for Economic Development, Transport and the Environment, responsible for the supervision of compliance with environmental permits. By combining these two national authorities into one permitting and supervisory authority, the government aims to streamline the national administration, as well as eliminate bottlenecks in environmental permitting processes.
Further, according to the draft proposal, certain permits under environmental protection legislation, water legislation, nature conservation legislation and chemical safety legislation could be handled simultaneously as one process, which could enable more co-ordinated permit and appeal proceedings. This initiative does not, however, cover building permits granted based on the Building Act.
A draft of the initiative has been sent out for comments in 2024, and the final proposal is being prepared by the government. The new authority organisation and other legislative changes are intended to take effect on 1 January 2026.
In Summary
The Finnish construction market is showing early signs of recovery after a prolonged downturn, though challenges remain in residential construction due to limited starts and tight financing. Growth areas include infrastructure, industrial projects and energy-efficient renovations.
Long-awaited negotiations have begun to modernise the nearly 30-year-old YSE 1998 general contract conditions.
Recent Supreme Court rulings have clarified key legal questions on post-warranty contractor liability, delay-related damages, and distinctions between construction-phase and warranty-period obligations. These rulings are expected to influence future contract risk management.
Finland is also progressing with permitting reforms to support clean transition projects. The new Building Act introduces a siting permit to accelerate planning for specific industrial green projects, while legislative initiatives are expanding fast-track permit handling and consolidating environmental permitting under a single authority by 2026. These changes aim to reduce regulatory bottlenecks and support the country’s broader climate and industrial goals.
