ALTO Ingénierie & Architecture

What ALTO Ingénierie & Architecture does

ALTO Ingénierie & Architecture is a Paris-headquartered structural engineering consultancy (bureau d'études) founded in 1989 by Marc Malinowsky, specializing in the structural design of complex, large-span works exceeding 15 meters, tensile membrane and ETFE structures, and heavy rehabilitation of concrete, steel, timber, and composite buildings. Its service offering is organized into four integrated modules: core structural engineering services, complex structures engineering, tensile structures and canopies, and new construction/renovation/rehabilitation. The firm integrates soil mechanics, material resistance, dynamics, acoustics, and computer simulation into multidisciplinary studies delivered from concept through execution support.

The company serves a mix of public-sector clients (municipalities and public entities delivering sports infrastructure, conference centers, and pedestrian bridges) and private enterprise clients (luxury brands and real estate developers), with a documented portfolio spanning Stade de Limoges, Stade de Villeurbanne, the Louis Vuitton production workshop at Condé, Lyon Confluence footbridge, and multiple Paris office rehabilitations. Geographically it operates across at least seven French regions, with the headquarters located at 3 rue Aumont-Thiéville in the 17th arrondissement of Paris.

Since 2019 ALTO has operated as part of the Archibuild group, a strategic combination that pairs its structural engineering practice with architectural expertise to offer integrated engineering-architecture services. Revenue is generated through project-based professional services fees on a quote-driven basis; no public pricing, no recurring SaaS or product revenue, and no financial disclosures are available. Headcount is reported at 5, with no AI/ML or software product disclosed, and the firm's competitive position rests on 35+ years of accumulated technical specialization rather than technology platform scale.

Core offering

ALTO is a structural engineering consultancy (bureau d'études structures) that provides comprehensive structural design services for complex construction and rehabilitation projects. The firm delivers structural studies from concept through detailed execution design for large-span sports facilities (stadiums, arenas, grandstands), tensile structures with ETFE and membrane coverings, and heavy rehabilitation of commercial, heritage, and infrastructure buildings in concrete, steel, timber, and composite materials.

Product overview

ALTO Ingénierie & Architecture is a single unified engineering service offering (not a software platform) that provides comprehensive structural engineering studies and design. The company operates as a structural engineering bureau with four integrated service modules: Core Structural Engineering Services, Complex Structures Engineering, Tensile Structures and Canopies, and New Construction/Renovation/Rehabilitation services. These modules work together to deliver projects from initial structural concept through to detailed component design, serving clients across sports facilities, commercial buildings, civil engineering structures, and architectural rehabilitation projects. The company joined the Archibuild group in 2019, expanding its capabilities to combine engineering and architectural expertise.

Direct peers

• Arup: Global structural and civil engineering consultancy renowned for complex, large-span, and tensile structures. Most directly comparable to ALTO in terms of structural design pedigree and high-prestige sports/cultural project portfolio.
• Bollinger+Grohmann: European structural engineering consultancy working closely with leading architects on complex buildings, facades, and timber/steel/concrete structures. Comparable boutique scale and design-led positioning.
• Schlaich Bergermann Partner: German structural engineering firm with a globally recognized specialism in tensile and lightweight structures, long-span roofs, and bridges. Directly comparable to ALTO's tensile/ETFE and bridge capabilities.
• Buro Happold: Independent engineering consultancy with strong specialism in complex structures, sports venues, and tensile/ETFE architecture. Comparable size tier and similar mix of stadium, heritage, and infrastructure work.
• RFR (Rice Francis Ritchie): Paris-based structural engineering firm with deep expertise in tensile and glass structures, founded by Peter Rice. Closest French peer to ALTO given shared specialty in lightweight, architecturally expressive structures and heritage-sensitive design.

Broad incumbents

• Setec: French engineering group with structural, civil, and project management practices serving transport, building, and energy sectors. Comparable on the French structural engineering market but at significantly larger scale.
• WSP: Global engineering consultancy providing structural and building services across transport, property, and environment. Overlaps with ALTO on stadia, large-span roofs, and bridge design as part of a much broader portfolio.
• Tractebel (Engie): Large European engineering consultancy operating across buildings, infrastructure, and energy. Competes for complex structural commissions across continental Europe and beyond.
• Egis: Major French engineering group offering structural, civil, and infrastructure services across transportation, buildings, and energy. Overlaps with ALTO's infrastructure and bridge work but at much larger scale and broader portfolio.
• Artelia: French multi-disciplinary engineering firm active in buildings, infrastructure, and industry. Competes for structural design commissions on commercial and sports projects but as a much broader generalist.
