COGEBAT

What COGEBAT does

COGEBAT (legal form CO GE BAT) is a privately held French construction economics consultancy organized as a SAS and headquartered in Grigny, Essonne in the Greater Paris region. Founded in 1983, the firm provides cost estimation, project economics analysis, and construction consultancy services to real estate developers, institutional asset managers, insurers, and select luxury-sector clients across France. Its service scope spans project values from €500K to over €50M, covering feasibility studies, cost planning, and economic oversight of construction programs. Notable clients include Nuveen, Covivio, Groupama Immobilier, Louis Vuitton Malletier, Amundi, Crédit Agricole Assurances, Monceau Investissements, PERIAL Asset Management, and Espacil Habitat.

The firm holds OPQTECC professional qualification (certification n°2391), a French industry-recognized credential for construction economics professionals, and has adopted BIM-IFC digital modeling capability as part of its technical stack. The team is small, comprising approximately 4–5 professionals led by CEO Cédric Dejardin, which positions COGEBAT as a boutique consultancy rather than a scaled platform. Service delivery is project-based and tied to underlying construction values, with fees typically structured as a percentage of project cost — a model that produces lumpy revenue tied to real estate development cycles.

The business model relies on long-tenured relationships with institutional and corporate clients, evidenced by repeat mandates across multiple project cycles. The firm's strategic posture is best characterized as stable niche specialization rather than growth-stage scaling, with ongoing recruitment suggesting incremental capacity expansion within a constrained boutique format. No M&A, funding events, or geographic expansion beyond France are evident in the available data.

Broad incumbents

• EGIS: Major French engineering and project management group with construction economics, AMO and building design capabilities. Competes with COGEBAT for institutional real estate mandates but operates as part of a much wider portfolio including infrastructure.
• SOCOTEC: Major French testing, inspection and certification group with adjacent construction economics and quantity surveying capabilities. Tangentially competes for cost-control engagements on institutional real estate projects at significantly greater scale.
• Ginger Groupe: Larger French engineering group offering construction economics, geotechnical, environmental and project management services. Overlaps with COGEBAT in the cost/quantity surveying and construction economics niche but at significantly broader scale.
• ARTELIA: Large French engineering and project management consultancy offering building economics, design and construction supervision. Directly competes for institutional rehabilitation mandates that COGEBAT services, but across a much broader multi-disciplinary portfolio.

Direct peers

• Cabinet Bérim: Paris-based independent engineering and construction economics consultancy serving institutional real estate clients across France. Closely comparable in scope (cost estimation, quantity surveying, project economics) and target customers, though generally larger than COGEBAT.
• Oteis: French independent engineering consultancy offering construction economics, project management and AMO services to real estate developers and investors. Directly overlaps with COGEBAT's économiste de la construction offering while operating at larger scale nationally.
• Verdi Ingénierie: French independent engineering firm providing construction economics, structural design, and environmental consulting for buildings. Comparable service profile to COGEBAT, particularly around cost planning and project economics for rehabilitation.
