INGES-BTP

What INGES-BTP does

INGES-BTP is a privately held French structural engineering consultancy (SARL) founded in 2020 in Bordeaux by Elian Marques, a 2012 graduate of École Supérieure d'Ingénieurs de Paris-Est. The firm specializes in the rehabilitation of existing buildings, offering structural diagnostics, disorder analysis, and project-management assistance. It operates with a small team of approximately four people as of early 2025, organized around a Bordeaux headquarters (9 rue de Condé) and a Champs-sur-Marne regional office covering Ile-de-France. The company is bootstrapped, carries minimal share capital (€5,000), and has no disclosed external investors.

The company delivers three interconnected service lines. The first, Diagnostic / Bureau d'étude, uses on-site investigation methods — non-destructive testing (radiography, pachometry), destructive testing (core drilling, sclerometry, steel reinforcement sampling), and laboratory compression/tensile testing — to characterize existing structures. The second, Expertises, provides disorder analysis (fire damage, pathologies, cracking, deformation, shock) for insurance experts, insured parties, and project owners. The third, AMO / AMOE, offers project-management assistance spanning contractor consultation, technical specifications drafting, quote review, and conformity analysis through work acceptance. Coverage spans residential, commercial, industrial, and heritage structures in wood, metal, concrete, masonry, vaults, balconies, and frameworks.

Revenue is generated on a project-based professional services model with custom quotes tied to scope and complexity. Customers span real estate developers (Linkcity, Angelys Groupe Bordeaux, Cote Ouest), social-housing operators (Logirep, Batigere IDF, France Horizon), large enterprises and institutions (SNCF, Bouygues, Société Générale, Poste Immo), insurance expertise firms (Saretec), and heritage sites (Château de Bruyères-le-Châtel). Go-to-market is direct, founder-led, and referral-driven, supported by a content-marketing program on the company blog and LinkedIn, and an opportunistic geographic footprint across Nouvelle Aquitaine, Ile-de-France, Occitanie, and Auvergne-Rhône-Alpes.
