What IDOM does
IDOM is a privately-held, multidisciplinary engineering, architecture, and consulting firm founded in 1957 and headquartered in Bilbao, Spain. The firm operates across more than 40 countries with a workforce of 5,001–10,000, delivering projects in data centers, water infrastructure, energy, heavy industry, rail and transit, buildings, and marine energy. Its core offerings span the full project lifecycle — feasibility studies, FEED (Front-End Engineering Design), detailed design, EPCm (Engineering, Procurement, Construction Management) contracts, and construction supervision — provided either directly or through consortia with peer engineering firms such as Técnicas Reunidas, Webuild, Larsen & Toubro, and Alstom.
The company's technology stack centers on BIM-based multidisciplinary coordination, proprietary methodologies in data center design (modular/brick architecture, non-traditional chilled-water free-cooling), and the MARMOK-A-5 oscillating water column wave energy converter deployed at BiMEP. It holds certifications including ISO 27001/27017/27018, Uptime Institute Tier III/IV, LEED Gold, ICREA IV/V, and BREEAM, qualifying it for sensitive public-sector and hyperscale mandates. Pricing is fully bespoke, negotiated per project scope on fixed-fee, time-and-materials, or EPCm terms with multi-year durations. Its customer base spans government and public administration (Royal Commission Riyadh, EIB, EJIE Basque Government, Hospital La Paz), enterprise industrials (ArcelorMittal, Hadeed, REE), and data center operators (AXTEL, FIVE Infinitum), distributed across a project-by-project delivery model with no standardized rate cards or self-serve channels.

Revenue model
- Engineering and Architecture Consulting Services: IDOM generates revenue through fee-based consulting, engineering design, and architecture services for infrastructure, buildings, industrial plants, data centers, water systems, and energy projects. Revenue is project-based, typically structured as fixed-fee contracts, time-and-materials mandates, or EPCm (Engineering, Procurement, Construction management) arrangements. Project scales range from feasibility studies and FEED phases to full design and construction supervision.
- EPCm (Engineering, Procurement, Construction Management) Contracts: Large-scale project delivery contracts where IDOM provides end-to-end engineering, procurement oversight, and construction management, often through consortiums with other firms. Revenue recognized over project execution timelines measured in years, with revenue recognition tied to project milestones.
- FEED (Front-End Engineering Design) Contracts: Pre-construction engineering design contracts that define project scope, specifications, and cost estimates before final investment decisions. Revenue is milestone-based and serves as a precursor to potential larger EPCm engagements.
- Data Center Full-Service Engineering and Architecture: Comprehensive consulting, architecture, civil engineering, electrical, HVAC, fire protection, BMS, and project management services for data center construction and expansion projects, covering the full project lifecycle from feasibility through construction supervision.
