Summary
- Equans recorded first-half order intake of €10.9 billion and a €27.6 billion backlog.
- Contracts above €5 million represented around 35% of new orders.
- Labour, controls, equipment, and commissioning capacity will determine how quickly the backlog converts into completed facilities.
Equans ended the first half of 2026 with a €27.6 billion backlog after securing a record €10.9 billion of new work, with data centres among the specialist markets contributing to larger technical-services contracts.
The backlog increased by €1.7 billion, or 7%, compared with the previous year. Contracts valued above €5 million rose substantially and represented around 35% of first-half order intake.
Sales reached €8.9 billion, while current operating profit from activities increased by €96 million to €460 million. Revenue declined on a reported basis, leaving the group with orders accumulating faster than completed work entered the accounts.
Large contracts carry longer delivery chains
Data centres sit alongside energy, transport, industrial, solar, and storage projects within Equans’ order book. The group does not disclose the proportion attached to mission critical facilities, although its data centre operation covers design, construction, mechanical and electrical installation, commissioning, maintenance, and operations.
Equans says it has delivered more than 300,000 sq m of IT space and over 500MW of IT power during 25 years of sector activity. Its project record includes facilities in the UK, France, the Netherlands, Belgium, Switzerland, and Austria.
Parent company Bouygues also reported a €17.9 billion construction backlog. Its construction division added approximately €235 million to an Australian data centre contract during the second quarter, following a further €130 million booked in the first.
The group’s first-half results place the data centre expansion cycle inside engineering and construction programmes rather than prospective development pipelines. Once a contract reaches a contractor’s backlog, teams, equipment, designs, and commissioning plans must be allocated against a delivery date.
Mission critical work is particularly sensitive to sequencing. Electrical distribution, cooling, controls, fire protection, security, and network systems must converge before integrated testing can start. A finished roof and weather-tight envelope leave much of the risk still inside the programme.
AI workloads add further coordination. Direct liquid cooling introduces coolant distribution units, heat exchangers, pipework, water-quality management, leak detection, and controls, while higher rack loads increase demands on substations, UPS systems, busway, and protection.
Interfaces can become contractual fault lines when responsibilities are divided among the server supplier, cooling manufacturer, MEP contractor, controls integrator, and operator. A system may perform correctly in isolation yet fail to respond properly when the full electrical and mechanical plant is tested together.
People and commissioning set the pace
European construction programmes are already competing for project directors, electrical engineers, commissioning managers, controls specialists, and authorised persons. A larger backlog cannot become revenue unless contractors can place experienced teams on each site without weakening delivery elsewhere.
The same pressure reaches subcontractors. Pipework specialists, switchgear installers, controls engineers, fire contractors, and commissioning agents are needed across several markets at once, while national certification and employment rules limit how freely teams can move.
Commissioning remains one of the narrowest points. Integrated systems testing must demonstrate how generators, UPS equipment, cooling plant, controls, and protection respond to failures, transitions, and partial loads. High density halls increase the consequence of incorrect settings or incomplete interfaces.
Phased construction can bring customer capacity online earlier, but it requires new work beside operational plant. Temporary arrangements must be clearly controlled, and shared systems need enough resilience to support live halls while subsequent buildings are connected.
Equipment availability adds another constraint. Contractors may reserve switchgear, generators, chillers, pumps, busway, and controls before every site condition is known. Early orders protect factory capacity, although they expose the programme to redesign and delayed grid dates.
Equans’ international scale allows engineering and procurement resources to be shared, but local delivery cannot be standardised completely. Planning conditions, electrical rules, labour markets, utility requirements, and construction practices differ across European jurisdictions.
The backlog spans many sectors, so it cannot be translated directly into data centre megawatts. It does show that large technical-services orders continue to accumulate, increasing the volume of work that must be engineered, installed, tested, and handed over during the next several years.
Equans has improved profitability while taking in more work. Preserving that performance will require disciplined contract selection and programme control, particularly where customers seek fixed dates while grid, design, or equipment dependencies remain outside the contractor’s control.
Europe’s proposed capacity pipeline is steadily becoming a delivery obligation. The limiting factors are moving from announcements and land positions into people, factory slots, site access, system integration, and the finite number of commissioning teams able to prove that each facility will remain operational when individual components fail.
