Türkiye’s construction mix highlights civil-engineering research opportunities for materials suppliers

Verified facts

• TÜİK reported a 4.7% year-on-year decline in the July 2026 construction-production index, alongside divergent changes across building construction, civil engineering and specialised construction activities. The index measures volume change at aggregate NACE sub-sector level, not a project pipeline or product order.
• The same release stated a 1.1% month-on-month rise in seasonally and calendar-adjusted construction production. A short-period movement does not identify a purchaser, material category, technical specification, inventory level, tender, margin or payment route.
• TÜİK reported a September 2026 construction-confidence index of 83.0, down 0.2% month on month. Confidence is a survey indicator, not a construction permit, budget, developer mandate, demand forecast or credit decision for a named material supplier.
• Türkiye’s Ministry of Trade Product Rules Database identifies the construction-products regulatory framework and related market-surveillance context. A framework must be checked against the exact product family, technical specification, declaration/performance evidence, economic operator and project acceptance route; it is not blanket conformity or customs clearance.
• European Commission construction-products material explains the European CPR structure and its reliance on applicable harmonised standards or European assessment documents. It is independent reference context and cannot decide the Turkish rule, local scope, transitional position, project specification or enforcement outcome for a product.
