Infrastructure Procurement Collusion

1. Introduction

Infrastructure procurement involves the acquisition of roads, bridges, railways, ports, airports, tunnels, utilities, energy infrastructure, water-treatment systems, telecommunications networks and large construction projects. Because these projects involve high contract values, repeated tenders and relatively small pools of qualified contractors, they are particularly vulnerable to bid rigging, price coordination, market allocation and unlawful consortium arrangements.

In competition law, infrastructure procurement collusion occurs when otherwise competing suppliers coordinate instead of independently competing for a public or private infrastructure contract. Typical arrangements include:

• agreeing in advance who will win a tender;
• submitting cover bids or deliberately high bids;
• rotating successful bidders;
• allocating geographical territories or projects;
• exchanging confidential tender prices;
• agreeing minimum prices;
• withdrawing bids in favour of another contractor;
• using a nominal consortium to eliminate competition;
• agreeing that losing bidders will receive subcontracting work;
• coordinating bids through an association, intermediary or "hub".

The Danish Competition and Consumer Authority specifically identifies bid rigging as an arrangement where competitors agree in advance who will bid, who will win and often the winning price.

For Denmark, the principal provisions are Section 6 of the Danish Competition Act and, where the effect on trade between EU Member States is capable of being established, Article 101 TFEU. Recent Danish enforcement has also demonstrated that coordination through an intermediary or pooling arrangement can constitute unlawful bid coordination even where competitors do not communicate directly with one another.

2. Legal Framework

A. Section 6 of the Danish Competition Act

Section 6 prohibits agreements, concerted practices and decisions by associations of undertakings that have as their object or effect the restriction of competition.

Infrastructure procurement collusion normally falls within the prohibition because competitors are expected to determine their:

• prices;
• production capacity;
• bidding strategy;
• allocation of contracts; and
• commercial terms

independently.

When competitors coordinate these matters, the procurement process ceases to reflect genuine competition.

B. Article 101(1) TFEU

Where the conduct is capable of affecting trade between EU Member States, Article 101(1) TFEU becomes relevant.

Infrastructure bid rigging can particularly raise Article 101 concerns where:

1. the contracting authority operates in a cross-border market;
2. contractors from several Member States can participate;
3. the infrastructure project is financed or structured at EU level;
4. the cartel affects cross-border supply of construction materials or services; or
5. the conduct forms part of a broader European cartel.

The Danish road-marking litigation expressly involved both Section 6 of the Danish Competition Act and Article 101 TFEU.

3. Why Infrastructure Procurement Is Particularly Vulnerable

Infrastructure markets have several characteristics that facilitate collusion.

1. Few qualified contractors

Large infrastructure projects often require:

• specialised machinery;
• engineering expertise;
• financial capacity;
• safety certifications;
• technical personnel; and
• previous-project experience.

Consequently, the number of realistic bidders may be relatively small.

2. Repeated tenders

Construction companies frequently encounter the same competitors in successive tenders.

This can facilitate:

"You win this project; we win the next one."

Such bid rotation can constitute market allocation.

3. High-value contracts

Infrastructure contracts can be worth millions or billions of currency units. Even a relatively small artificial increase in the contract price can create substantial unlawful gains.

4. Similar cost structures

Competitors may have similar:

• labour costs;
• materials costs;
• equipment costs; and
• project schedules.

This can make coordinated pricing easier to conceal.

5. Geographic segmentation

Roads, railways, utilities and regional infrastructure projects are naturally divided geographically.

This creates opportunities for competitors to allocate:

• regions;
• municipalities;
• project types; or
• individual contracts.

4. Main Forms of Infrastructure Procurement Collusion

A. Bid Rotation

Competitors decide in advance which undertaking will win particular tenders.

Example:

The remaining contractors submit intentionally unattractive bids.

B. Cover Bidding

Competitors submit bids that are deliberately higher than the predetermined winner's bid.

For example:

• X: €10 million — intended winner
• Y: €12 million — cover bid
• Z: €12.5 million — cover bid

The procurement authority sees several bids but does not receive genuine competition.

C. Bid Suppression

A competitor agrees not to bid.

The non-bidding company may subsequently receive:

• subcontracting work;
• another project;
• compensation; or
• an agreed share of profits.

D. Market Allocation

Contractors divide infrastructure opportunities geographically or by project category.

For example:

• Company A → northern region;
• Company B → southern region;
• Company C → bridges;
• Company D → tunnels.

Such arrangements may constitute market-sharing in addition to bid rigging.

E. Price Information Exchange

Competitors exchange:

• intended bid prices;
• labour costs;
• material costs;
• discounts;
• margins;
• quantities;
• tender strategies; or
• technical assumptions.

The central problem is that the tenderer is no longer determining its bid independently.

F. Consortium Collusion

A consortium is not automatically unlawful.

Joint bidding may be legitimate where firms genuinely need one another's:

• capacity;
• technology;
• equipment;
• financing;
• technical expertise; or
• workforce.

The competition concern arises when two actual competitors capable of bidding independently combine merely to eliminate competition between themselves.

The Danish road-marking litigation is particularly important on this issue.

5. At Least 6 Important Case Laws / Enforcement Decisions

Case 1: LKF Vejmarkering A/S & Eurostar Danmark A/S — Road-Marking Consortium

This is one of the most important Danish infrastructure procurement cases.

The Danish Road Directorate invited tenders for road-marking services covering three Danish districts. LKF Vejmarkering and Eurostar Danmark were major competitors and formed a consortium to submit joint bids.

The Competition Council found that the consortium infringed competition law because the companies could have independently participated in the tender.

The Competition Appeals Tribunal upheld the finding in 2016. The litigation subsequently reached the Danish Supreme Court, which in 2019 concluded that the consortium infringed the Competition Act.

The later criminal proceedings also resulted in the Eastern High Court finding the consortium agreements criminally unlawful, although punishment was ultimately waived because of the particular circumstances and lengthy proceedings.

Principle

A consortium between competitors may infringe competition law where the parties could independently have competed and the cooperation eliminates competitive bidding.

This is especially important for:

• road construction;
• road maintenance;
• railway infrastructure;
• civil engineering;
• public works.

Case 2: Jorton A/S & H. Skjøde Knudsen A/S — Construction Bid Rigging

In this case, two construction companies were prosecuted for coordinating bids in three public procurements between January 2012 and August 2013.

The companies exchanged prices and coordinated their bids. The Danish High Court subsequently imposed substantial fines after the City Court had initially acquitted them.

The case demonstrates that the exchange of confidential price information is not merely a procedural irregularity.

Principle

Competitors cannot exchange intended tender prices or coordinate bids in public infrastructure procurement.

The case is particularly relevant to:

• public construction;
• building projects;
• civil engineering;
• municipal infrastructure.

Case 3: Greater Copenhagen Building Cartels

The Danish authorities uncovered a large series of construction-sector bid-rigging arrangements involving numerous companies.

The companies rigged prices for construction contracts worth approximately DKK 400–500 million. Ultimately, fines totalling approximately DKK 31 million were imposed on 25 companies and 21 executives.

The case demonstrates the danger of systemic cartelisation, rather than isolated coordination between two companies.

Principle

Infrastructure procurement collusion can operate as a continuing network involving:

• repeated tenders;
• multiple competitors;
• coordinated prices;
• recurring allocation arrangements; and
• management-level participation.

Case 4: Demolition Companies — Construction and Infrastructure Works

Several demolition companies were prosecuted for exchanging prices with competitors in connection with demolition tenders.

G. Tscherning A/S, for example, accepted a substantial fine concerning 12 cases involving the exchange of prices with competitors. Other demolition companies also entered settlement agreements.

Although demolition is a specialised component of construction rather than an infrastructure project in every case, it is highly relevant because demolition contracts frequently form part of:

• road projects;
• urban redevelopment;
• transport infrastructure;
• public construction;
• redevelopment of infrastructure sites.

Principle

Price exchanges between competitors concerning specific tenders can amount to prohibited bid rigging even where the underlying project is only one component of a larger infrastructure development.

Case 5: Fredensborg VVS-Teknik A/S — Plumbing Procurement

Fredensborg VVS-Teknik accepted a fine after coordinating bids and exchanging price information with a competitor in five cases in the Copenhagen area.

The conduct occurred between April 2012 and August 2013 and concerned public procurement.

The case illustrates that procurement collusion is not confined to the principal infrastructure contractor.

It can arise at the level of:

• plumbing;
• electrical works;
• HVAC;
• mechanical installation;
• utility connections; and
• specialised subcontracting.

Principle

Competition law applies throughout the infrastructure supply chain, not merely to the prime contractor.

Case 6: Sanoterm Danmark A/S — Cruise Terminal Plumbing Works

A particularly useful example concerns Sanoterm Danmark A/S.

The company and a competitor exchanged information about prices and other terms in connection with plumbing work for a new cruise ship terminal. A management member ultimately accepted a personal fine.

This is directly relevant to infrastructure procurement because the project concerned a major transport-related infrastructure facility.

Principle

Coordination of prices and commercial terms in a specialised infrastructure subcontract can constitute an infringement even where the parties are not competing for the entire infrastructure project.

Case 7: Effekthandel ApS and 49 Power Plants — Energy Infrastructure Procurement

A particularly significant modern Danish case concerns the procurement of balancing reserves in Western Denmark.

Effekthandel and 49 cogeneration and power plants participated in a pooling arrangement concerning auctions for manual Frequency Restoration Reserve (mFRR).

The participants agreed to leave pricing of their bids to Effekthandel. The Danish Competition Council found that the arrangement infringed Section 6 and Article 101(1) TFEU.

The Competition Appeals Tribunal subsequently upheld the infringement in relation to Effekthandel and eight participating plants.

The Maritime and Commercial High Court later dealt with six test cases and found unlawful coordination of bids and prices.

Principle

A cartel does not require competitors to communicate directly with each other.

Coordination through a central intermediary or pool operator can still constitute unlawful coordination.

This principle is highly relevant to:

• electricity procurement;
• energy infrastructure;
• capacity markets;
• balancing services;
• grid-related procurement;
• reserve-capacity auctions.

6. Hub-and-Spoke Infrastructure Collusion

A particularly important modern form is the hub-and-spoke arrangement.

Structure

             Contractor A                  |                  | Contractor B — HUB / INTERMEDIARY — Contractor C                  |                  |             Contractor D

The intermediary may:

• collect prices;
• communicate bidding information;
• determine pricing;
• distribute market information;
• coordinate bids; or
• allocate revenues.

The Effekthandel case illustrates why the absence of direct competitor-to-competitor communication does not necessarily save an arrangement from competition-law liability.

7. Information Exchange in Infrastructure Procurement

Information exchange is especially sensitive immediately before or during a tender.

High-risk information includes:

1. intended tender price;
2. minimum acceptable price;
3. expected profit margin;
4. planned bid;
5. whether a company intends to bid;
6. capacity available for the project;
7. identity of subcontractors;
8. cost calculations;
9. discount strategy;
10. technical assumptions affecting price.

The Danish Competition Authority's procurement guidance and enforcement materials recognise bid-rigging indicators such as unusually similar bids and competitors sharing calculations or prices.

8. Cover Bids and "Loan Prices"

A particularly deceptive practice is the cover bid.

Suppose a contractor is designated as the cartel winner.

The other participants submit intentionally inflated bids.

Another variation is a loan price, where one contractor provides another with a price calculation or bid figure so that the tender appears competitive.

This can be particularly difficult for contracting authorities to detect because multiple bids are technically submitted.

9. Subcontracting as Compensation

An unsuccessful bidder may receive compensation through subcontracting.

For example:

Contractor A agrees to win the main contract.
Contractors B and C submit higher bids.
A subsequently awards subcontracting work to B and C.

This can preserve the cartel because the losing bidders are not necessarily economically disadvantaged.

The European Commission's procurement-fraud materials identify patterns such as losing bidders becoming subcontractors as indicators that may warrant investigation.

10. Market Allocation in Infrastructure

Infrastructure markets are especially susceptible to geographical allocation.

For example:

             Infrastructure Market                     |       ┌─────────────┼─────────────┐       ↓             ↓             ↓   Region A       Region B       Region C       |             |             | Company X       Company Y      Company Z

The companies may agree not to compete for each other's geographic territories.

The arrangement can operate without explicit price fixing because the allocation itself removes competitive pressure.

11. Tender Rotation

Another common mechanism is rotating winners.

Example:

The other firms submit non-competitive bids.

Tender rotation is particularly dangerous where the same companies repeatedly encounter one another in public procurement.

12. Procurement Authority's Role

A contracting authority can reduce collusion risks through tender design.

Important safeguards include:

A. Increasing participation

Where possible, procurement should avoid unnecessary technical or financial requirements that exclude otherwise capable bidders.

B. Independent bid evaluation

Tender information should be handled confidentially.

C. Monitoring suspicious patterns

Authorities can examine:

• identical prices;
• identical calculation errors;
• unusual bid gaps;
• repeated winning patterns;
• unexplained withdrawals;
• subcontracting relationships;
• common consultants;
• common contact details.

The Danish Competition Authority has developed Bid Viewer tools using screening indicators to identify potentially suspicious collusive bidding patterns.

13. Red Flags in Infrastructure Procurement

A procurement authority should investigate patterns such as:

Pricing indicators

• identical bids;
• nearly identical bids;
• unusual price differences;
• repeated percentage differences;
• unexplained price increases;
• bids that appear systematically high.

Behavioural indicators

• regular winner rotation;
• competitors taking turns winning;
• qualified companies repeatedly refusing to bid;
• competitors withdrawing bids;
• competitors using the same subcontractors.

Documentary indicators

• identical typographical mistakes;
• identical spreadsheets;
• identical calculation errors;
• metadata linking bid documents;
• common consultants;
• common addresses or telephone numbers.

The European Commission's Anti-Fraud Knowledge Centre similarly identifies identical offers, common errors, common personnel and competitors becoming subcontractors as potential bid-rigging indicators.

14. Legitimate Cooperation vs Collusion

Not every joint infrastructure bid is unlawful.

This distinction is essential.

The Danish authorities expressly recognise that many consortia can be legitimate, particularly where participants are not competitors or the cooperation produces genuine competitive benefits.

15. Cementa/Aalborg Portland — Great Belt Bridge Example

The Danish Competition Authority's guidance on joint bidding discusses the Cementa/Aalborg Portland case involving cement supply for construction of the Great Belt Bridge.

The undertakings sought permission to bid jointly. The Swedish Competition Authority considered potential efficiency gains but raised serious concerns because the parties had extremely high combined market shares and foreign entry was difficult.

Significance

Infrastructure importance does not automatically justify cooperation between competitors.

Even where cooperation may produce efficiencies, authorities must consider whether it substantially eliminates competition.

16. Effect on Public Funds

Infrastructure procurement collusion can cause several types of harm.

1. Higher contract prices

The government or public authority pays more than it would under competitive conditions.

2. Lower value for money

Higher prices can result in:

• fewer infrastructure projects;
• reduced maintenance;
• lower project quality; or
• budget overruns.

3. Reduced innovation

Competition normally encourages contractors to offer:

• better construction methods;
• faster completion;
• improved technology;
• lower lifecycle costs.

Collusion reduces these incentives.

4. Market foreclosure

Smaller or new contractors may be prevented from entering markets controlled by established cartel participants.

17. Relationship with Public Procurement Law

Competition law and procurement law operate alongside one another.

A contracting authority confronted with suspected collusion may consider:

• exclusion of the undertaking where legally permitted;
• cancellation of the tender;
• redesign of the procurement;
• referral to competition authorities;
• damages or contractual remedies;
• criminal or administrative sanctions, depending on the jurisdiction.

The European framework also contains additional mechanisms addressing distortive subsidies in procurement. Under the EU Foreign Subsidies Regulation, for example, the Commission can investigate certain large public procurement bids where foreign subsidies may distort the internal market.

That is conceptually different from cartel collusion, however: foreign-subsidy distortion and bid rigging should not be treated as the same legal infringement.

18. Sanctions and Liability

Infrastructure procurement collusion can expose participants to:

• corporate fines;
• individual liability;
• criminal sanctions in applicable systems;
• damages claims;
• exclusion from procurement;
• reputational damage;
• loss of future government contracts.

The Danish cases demonstrate that liability can extend beyond companies to individual management members. The Jorton/H. Skjøde Knudsen case, for example, resulted in fines for both companies and members of management.

19. Compliance Measures for Infrastructure Contractors

Companies participating in infrastructure tenders should implement:

Before tender

• competition-law training;
• written bidding protocols;
• competitor-contact restrictions;
• approval procedures for consortium formation;
• independent preparation of prices.

During tender

• separate bid teams;
• restricted access to pricing information;
• no communication of intended prices;
• documented justification for consortium arrangements;
• careful treatment of subcontractor discussions.

After tender

• preserve bid records;
• document legitimate business reasons for pricing;
• investigate unusual competitor contacts;
• maintain audit trails.

20. Practical Compliance Test for Joint Bidding

Before two competitors submit a joint infrastructure bid, ask:

Question 1

Could each company independently perform the contract?

Question 2

Could each company independently satisfy the tender's minimum requirements?

Question 3

Does the cooperation eliminate competition that would otherwise exist?

Question 4

Are there genuine efficiencies?

Question 5

Are those efficiencies passed on through stronger competitive conditions?

Question 6

Is the cooperation broader than necessary?

Question 7

Have the companies exchanged competitively sensitive information?

If independent bidding is realistically possible and the cooperation removes competition, substantial competition-law risk arises. The LKF/Eurostar road-marking litigation illustrates this principle particularly clearly.

21. Key Case-Law Principles

22. Conclusion

Infrastructure procurement collusion is one of the clearest forms of horizontal competition restriction. The central legal concern is the replacement of independent tendering with coordinated conduct.

The most important prohibited mechanisms are:

1. bid rotation;
2. cover bidding;
3. bid suppression;
4. price coordination;
5. market allocation;
6. exchange of tender information;
7. unnecessary competitor consortia;
8. hub-and-spoke coordination; and
9. compensation through subcontracting.

The Danish road-marking cases demonstrate that a consortium can be unlawful where competitors could independently bid, while the Effekthandel proceedings demonstrate that sophisticated coordination through a central pool or intermediary can also constitute bid rigging.

For infrastructure procurement, therefore, the decisive competition-law question is not simply whether companies formally submitted separate bids, but whether the tendering process preserved genuine independent competitive decision-making.
