Contractors beware: clauses requiring employer pre-approval of additional work costs
Switzerland | 10 September 2018

Clauses that require a contractor to obtain the employer's pre-approval of the cost of any additional works are increasingly common in lump-sum construction contracts. According to a recent Federal Supreme Court decision, these pre-approval clauses will be applied strictly, subject to certain exceptions. In its decision, the court enforced such a clause to deny a contractor's claim to recover the cost of additional works performed by a subcontractor.

Contractors' obligation of diligence and duty to inform persist even after termination
Switzerland | 02 July 2018

A recent decision by the Swiss Federal Supreme Court ruled that a contractor's duty of loyalty continues even after termination by the employer. When the contractor stops its works for any reason, it has the duty to take all necessary measures to prevent any harm to the employer and must provide to the employer all relevant information about the works.

Pricing unilateral change orders in lump-sum contracts
Switzerland | 26 March 2018

The Supreme Court has for the first time interpreted the provisions on the pricing of change orders in the most widely used Swiss standard form contract, the SIA Norm 118. But the decision also has wider ramifications for Swiss law construction contracts. It makes clear that it should be assumed that parties to a lump-sum contract intended to contractually regulate the effect on the contract price of a unilateral change order, even if the terms of the contract are ambiguous.

Regulatory changes and force majeure – impact on lump-sum and build-operate contracts
Switzerland | 13 November 2017

Swiss courts and arbitrators have addressed the interface between force majeure clauses and regulatory changes, and how they impact on the contractor's entitlements. Clauses addressing unforeseen circumstances will be construed in line with the parties' actual intentions. If they cannot be established from the text and surrounding circumstances and evidence, the tribunal will construe the clause objectively, regarding how it can be understood in good faith.

No contractor liability for defects visible at final inspection except concealed defects
Switzerland | 09 October 2017

Employers should keep a watchful eye on contractor variations and ensure that they do not modify any important quality or original requirements specified in the contract. Whatever the length of the contract, the employer is duty bound to notify any deviation from the contract on final inspection. However, the courts will not protect a contractor which has fraudulently concealed a defect or prevented the employer from discovering a defect.

Valid change orders can amount to breaches of employer's ancillary obligations
Switzerland | 10 April 2017

Employers typically have the power to vary works, including by making changes to the sequence or timing of their execution. Sometimes, these variations do not entitle the contractor to additional remuneration. However, as confirmed by a recent Federal Supreme Court decision, even a change order that is permitted under a contract could result in a breach of the employer's ancillary obligations and therefore give rise to a right to compensation.

Implicit employer approval of progress reports
Switzerland | 13 February 2017

Many construction contracts provide that the contractor must submit daily, weekly or monthly progress reports, which then serve as a basis for invoices or applications for payment certificates. In some cases, the contract provides that these progress reports must first be approved by the employer. A recent case before the Supreme Court demonstrates that, in certain circumstances, such approval may be implied through the employer's silence.

The consequence of skipping a mandatory pre-arbitral step
Switzerland | 05 December 2016

In mid-2014 the Supreme Court ruled that the requirement in the International Federation of Consulting Engineers Conditions to submit a dispute to a dispute adjudication board was a mandatory precondition for arbitration, but avoided the question of what the consequence for failing to comply should be. In a recent decision that is particularly important for international construction contracts, the court provided welcome guidance on a question that often arises in construction disputes.

Do erroneous tender documents entitle a lump-sum contractor to additional remuneration?
Switzerland | 23 May 2016

A lump-sum contractor may be entitled to additional remuneration if its work is rendered more difficult due to a fault of the employer. But what happens if the contractor is aware of the employer's fault? A lump-sum contract will not protect employers from having to pay additional remuneration to the contractor for costs that the latter has incurred due to a fault of the employer or its representatives.

Limitations on right to terminate entire construction contract for delay to only part of works
Switzerland | 21 December 2015

The Federal Supreme Court has limited an owner's right to terminate a contract in case of delays attributable to the contractor. The owner's interest in terminating the entire contract must be worthier of protection than the contractor's interest in keeping it in place for the works that are on time. Owners should avoid setting unreasonably short time limits to remedy delays and contractors should object immediately to unreasonably short grace periods.

Technical and safety standards – impact on owners' non-contractual liability
Switzerland | 12 October 2015

In a recent decision the Supreme Court clarified the relevance of the Swiss Society of Engineers and Architects' standards for planning and construction in relation to the owner's third-party liability. The court held that an increase of technical norms indicates an increased risk arising from the respective work, against which the owner must take all reasonable and adequate protective measures.

Supreme Court – DAB proceedings precondition for arbitration under FIDIC Conditions
Switzerland | 13 October 2014

The Federal Supreme Court recently analysed whether dispute adjudication board (DAB) proceedings are a precondition that must be met before resorting to arbitration under the International Federation of Consulting Engineers (FIDIC) Conditions of Contract. The court recalled that the introduction of the DAB in the FIDIC conditions was to allow for an efficient resolution of disputes arising during construction works.

Will new Swiss sanctions against Russia affect construction projects?
Switzerland | 22 September 2014

Sanctions imposed by the Swiss government are of particular importance to the international construction industry. Construction contracts governed by Swiss law may be deemed null and void if they are in breach of sanctions, regardless of whether the parties have any link to Switzerland. Construction practitioners should therefore note a new ordinance imposing commercial and financial restrictions against Russian interests in relation to Ukraine.

Additional works performed with owner's knowledge but without formal approval
Switzerland | 14 April 2014

An owner refused to pay for alleged additional work, claiming that it had not been aware of any changes. The contractor sued the owner claiming the amount it quoted for the new work. The Supreme Court accepted that an owner could be ordered to pay a contractor for the value of the work as a whole. The case highlights the clash between contractual requirements of form and good-faith reliance on the other party's conduct.

Impact of embargoes on construction contracts - Swiss sanctions against Iran
Switzerland | 17 June 2013

Switzerland has adopted a number of sanctions against Iran. These sanctions may affect construction contracts if, among other things, one of the parties is blacklisted or the construction contract concerns works falling under the restrictions imposed by the sanctions. Any breach of the sanctions would be considered to be illegal and entail the nullity of the contract.

Amendments extend warranty claim time limit and modify terms and conditions rules
Switzerland | 04 February 2013

The statutory time limit for warranty claims has been extended from one to two years. The two-year time limit is mandatory only for consumer contracts. Contracts between businesses may still provide for shorter limitation periods for warranty claims. In addition, a recent revision of the Unfair Competition Act allows tribunals to invalidate general terms and conditions that are unfair towards consumers.

Time limits for main contractor's warranty claims against subcontractors
Switzerland | 05 November 2012

The Federal Supreme Court recently confirmed that a main contractor can align the contractual time bars for warranty claims against its subcontractors with the time limits applying to warranty claims that the owner has against the main contractor. This decision is relevant for both main contractors and subcontractors involved in large construction projects.

Failure to submit progress reports not fatal to compensation claim
Switzerland | 25 June 2012

The controversial issue in a recent court of appeal case was whether the contractor still had a claim for compensation, despite its failure to submit progress reports and have them signed by the owner. The court ruled that in the absence of the contractually agreed progress reports, the contractor was still entitled to compensation but should establish (the amount of) its claim by other means of evidence.

Right to rescind: delayed and unfulfilled construction contracts
Switzerland | 19 March 2012

The Supreme Court recently confirmed that an owner may rescind a contract for works if the contractor is in default. Before doing so, the owner must put the contractor on notice and grant it a reasonable grace period. In the present case, the contractor failed to reach agreed-upon output requirements and its delivery of the works was late. The court held that no prior notice or grace period was required in these circumstances.

Warranty claims extended for sale of goods: impact on construction contracts
Switzerland | 21 November 2011

It is expected that the upper house of the Swiss Parliament, the Council of States, will approve an amendment to the Code of Obligations which will align Swiss law on warranties with the UN Convention on Contracts for the International Sale of Goods and the EU Sale of Consumer Goods Directive. Since the rules on warranties applicable to the sale of goods under Swiss law also apply to contracts for works, the extension of the time limit will also impact on Swiss construction law.

Owner's liability for ground conditions and duty of care towards contractor
Switzerland | 09 May 2011

The scope of liability between owner and contractor with regard to subsoil conditions that affect the location where works are performed is often a source of dispute. The Supreme Court recently applied the duty of care in a case where a contractor's equipment was damaged by obstacles on the ground. The court's findings may be applied to construction contracts in general.

Remedies for contractor's refusal to repair defective works
Switzerland | 07 March 2011

Contracts for works are regulated by Articles 363 to 379 of the Code of Obligations. The interface between these specific provisions and those applicable to all contracts under the General Part of the code raises thorny issues, as was illustrated by a recent Federal Supreme Court decision in which the court had to deal with the remedies available to the owner in case of the contractor's default.

New case law regarding defect notice requirements
Switzerland | 31 August 2010

In two recent decisions, the Federal Supreme Court has reaffirmed a number of rules regarding defect notices. While neither judgment overturned or modified existing precedent, the principles underlying the court's findings are of paramount importance for contracts governed by Swiss law.

Failure of performance tests and contractual grounds for termination
Switzerland | 01 March 2010

Many of the international arbitrations conducted in Switzerland relate to construction and engineering contracts and contracts for the supply of equipment for industrial plants and construction projects. A Federal Supreme Court decision sheds light on an award that dealt with the relationship between statutory and contractual grounds for termination of a works contract where the failure of performance tests was alleged.

Timeliness of Defect Notices in the Event of Uncertain Liability of Multiple Contractors
Switzerland | 03 August 2009

A recent Supreme Court decision confirmed the opinion that, in the event of the discovery of a defect with uncertain liability between multiple contractors, the owner must establish not only the existence of a defect, but also which contractor is contractually liable for that defect. Only at that point does the time limit to notify defects commence.

Veto Rights Within a Construction Consortium
Switzerland | 01 June 2009

A recent case demonstrated that, in disputes over a consortium member's refusal to pay for supplies additional to those stated in the building contract, a contractual veto right is not unlimited. The case showed the member's right to refuse to provide additional supplies without additional payment, although it is unlikely that a veto right could allow a party to refuse to provide such supplies where additional payment has been offered.

Guarantees: Limitation of Liability and Dispute Resolution Clauses
Switzerland | 01 December 2008

Bank or parent company guarantees can be used in construction projects to guarantee payment by the employer, delivery of the project, performance of the works or that a party keep a tender offer open during a certain period, among other things. In 2008 the Swiss Supreme Court rendered three important judgments dealing with disputes arising from these guarantees.

Notice Requirements in Cases of Hidden and Evolving Defects
Switzerland | 18 August 2008

Short time limits for notices are a typical feature of construction contracts and statutes. In practice, disputes often arise regarding the date on which a defect was or could have been discovered, the nature of the defect (apparent or hidden) and the validity of the notice of the defect. The Supreme Court addressed some of these issues in a recent decision.

Owner's Defect Notice and Remedies in Case of Hidden Defects
Switzerland | 18 February 2008

Swiss law and many international standard forms contain requirements which owner's defect notices must meet. In a recent case involving defective material used by the contractor, the Supreme Court highlighted the stringent requirements as to the form and substance of the notice, but added that the circumstances may warrant more lenient application. The court examined statutory remedies available to the owner.

Public Procurement in Construction Projects: Issues for Foreign Contractors
Switzerland | 12 November 2007

Public tenders for construction projects in Switzerland are heavily regulated by federal, cantonal and municipal laws. This update identifies a number of issues which foreign contractors may have to deal with in case they participate in tender proceedings in Switzerland.

Contract Termination: Rights and Obligations of Employers and Contractors
Switzerland | 10 September 2007

Swiss law distinguishes between terminations of contract for good cause and those for convenience. While the former are premised on proof of the contractor’s fault, the latter provide the employer with a right to terminate at any time, provided that it fully compensates the contractor. In a new precedent the Supreme Court introduced the possibility of reducing the amount of such compensation on equitable grounds.

Standing of Consortium Members in Consortium Disputes with Third Parties
Switzerland | 29 May 2007

The outcome of a recent construction dispute indicates that contracts providing for cooperation between contractors should establish expressly the consortium's relationship with third parties. If the members of the consortium sign a contract with third parties jointly, they should clearly determine the circumstances in which one of the partners can alone negotiate with, settle claims and sue the third party.

Pricing of Additional Works
Switzerland | 16 April 2007

The Federal Supreme Court recently elaborated on some crucial aspects of construction law, particularly relating to the pricing of works beyond the initial scope of the contract issues. The scope of the engineer's powers of representation and the consequence of a party's failure to object to any aspects of the contract during the performance of the works were also addressed.

The Contractor’s Right to Remedy Defects
Switzerland | 18 December 2006

The Swiss Federal Supreme Court has elaborated on the conditions that must be met before the owner can request a third party to remedy defects allegedly caused by the contractor. Contractors confronted with an owner's defect notice are well advised to draft their reply carefully in order to ensure that the owner cannot order a third party to perform the works at the contractor's cost.

New Case Law on the Taking Over of a Turnkey Plant
Switzerland | 20 November 2006

A recent construction dispute concerned alleged defects. The supplier argued that the owner had taken over the plant and that the claim for defects was time barred. The owner claimed that it had not yet taken over the plant and that the defect liability period had not begun. The tribunal held that delivery and taking over are in fact the same event, and that the works need not be without defect to be delivered.

International Construction Contracts under Swiss Law: An Outline
Switzerland | 10 July 2006

Swiss law often applies to international construction contracts. It is concise and easily accessible, and is often chosen as 'neutral' law to govern the main contract in a construction project and, more frequently, ancillary contracts - in particular, subcontracts. In the absence of a choice of law, the Swiss conflict of law rules point to the law of the party providing the service - that is, the contractor.

Energy & Natural Resources

The consequence of skipping a mandatory pre-arbitral step
Switzerland | 28 November 2016

In a recent case, the Supreme Court finally addressed the question of what the consequence for failing to comply with a mandatory pre-arbitral condition should be. The decision is particularly important for international construction contracts and other contracts in the energy sector, which often contain multi-tier dispute resolution clauses requiring parties to resort to mediation, conciliation, dispute boards or dispute adjudication boards before initiating arbitration.

Authorisation process for construction of new nuclear power plants suspended
Switzerland | 28 March 2011

In the aftermath of the Japanese earthquake and the accidents that ensued at the Fukushima nuclear power plants, the Swiss Federal Department of Environment, Transport, Energy and Communications has suspended the authorisation process for the construction of new nuclear power plants in Switzerland. The suspension will be in effect "until safety standards have been carefully reviewed and if necessary adapted".

International Trade

Swiss sanctions against Iran
Switzerland | 12 July 2013

Switzerland has adopted sanctions against Iran by transposing into Swiss national law the United Nations' sanctions and certain EU and US sanctions. Current Swiss sanctions include a blacklist of Iranian companies with which any business transactions are prohibited. However, there is no ban on oil and gas trades and related financial transactions – merely a duty to report such transactions.

Projects & Procurement

AlpTransit Gotthard SA builds world's longest railway tunnel
Switzerland | 27 July 2010

The Gotthard Base Tunnel is part of the Sfr20 billion AlpTransit project to build a new rail link through the Alps, with the objective of creating a direct and level route for high-speed passenger and freight trains. The Gotthard tunnel project was one of the first in Switzerland where foreign contractors were admitted to bid, and they were actually awarded many of the lots.
