What ECONOMIE80 does

ECONOMIE80 is a French construction economics and engineering firm (économiste de la construction) founded in 1965, headquartered in Bois Guillaume, Normandy, with a secondary office in Caen. The firm provides technical and economic design expertise during construction and renovation operations, operating as a member of maîtrise d'œuvre teams or in design-build arrangements for public and private sector clients across metropolitan France and DOM-TOM territories.

The firm's offerings are organized into four specialized poles: Pôle Economie (feasibility studies, cost estimation, quantity surveying, OPQTECC certified); Pôle Thermique (thermal regulatory studies under RT 2012 and RE 2020, DPE diagnostics, Passivhaus labeling, OPQIBI certified with RGE designation); Pôle Fluides (MEP engineering, HVAC, plumbing, electrical); and Pôle VRD (roads and utilities networks). These poles operate within a BIM (Building Information Modeling) process at Levels 1 and 2 with stated orientation toward Level 3, using Revit Architecture, Revit MEP, and Clima-Win software for 3D digital coordination and data exchange with project stakeholders.

ECONOMIE80 generates revenue through project-based professional services engagements as an economist of the construction and engineering study provider. Fees are determined per project based on scope, complexity, and client requirements, with no publicly disclosed pricing. The firm is managed by Grégory Larcheveque (Gérant), is privately held with no disclosed external investment or parent company, and maintains a multidisciplinary team of approximately 15-20 professionals including economists, quantity surveyors, engineers, and BIM technicians.
