What TAŞYAPI İNŞAAT SAN. ve TİC. A.Ş. does

Taşyapı İnşaat San. ve Tic. A.Ş. is a privately held Turkish general contractor founded in 1980 by S. Temel Taşkın and headquartered in Bakırköy, Istanbul, with approximately 110 employees. The company operates three integrated service lines: Infrastructure Works (Altyapı), covering TBM-driven stormwater tunnels, drinking water transmission lines, sewage and stormwater networks, trenchless pipe installation, bridges, and roads; Superstructure Works (Üst Yapı), covering cultural centers, municipal service buildings, healthcare and educational facilities, sports complexes, mass housing, and seismic retrofitting; and Restoration (Restorasyon), covering heritage conservation for mosques, palaces, churches, the Grand Bazaar, and other cultural monuments. Its technology stack centers on heavy civil engineering equipment — tunnel boring machines, pipe jacking, horizontal directional drilling, ductile iron and steel pipe systems, and SCADA-based infrastructure monitoring.

Revenue is generated primarily through competitive bidding for public sector contracts, with the Istanbul Metropolitan Municipality and its water utility İSKİ as anchor clients, supplemented by work for Vakıflar Genel Müdürlüğü, Milli Saraylar İdaresi Başkanlığı, DSİ, and several Turkish universities. The go-to-market is enterprise field sales into a closed tender ecosystem rather than outbound marketing. The customer base is overwhelmingly government, with limited private sector activity. The company has delivered 80+ projects across Istanbul and other Turkish provinces (Rize, Edirne, Kırklareli, Kırıkkale, Trabzon) and has a single flagged international project in Bulgaria, and diversified into tourism with Hotel Taşkın in Trabzon in 1996.

• Doğuş İnşaat: Major Turkish contractor with strong heritage in large-scale infrastructure and public works. Direct overlap on transportation, water, and public building contracts with Turkish state entities.
• Yapı Merkezi: Turkish infrastructure and construction firm with strong track record in metro, rail, tunnels, and water projects. Comparable in tunneling expertise (TBM) and public-sector contracting model.
• Makyol İnşaat: Turkish contractor active in infrastructure, superstructure, and public-private partnership projects. Overlaps directly with Taşyapı on transportation, water, and municipal construction tenders across Turkey.
• Kalyon İnşaat: Turkish infrastructure group with deep municipal relationships and capabilities in water, sewage, and transportation projects. Closely comparable to Taşyapı's ISKI and Istanbul Metropolitan Municipality work.
• Koltek Mühendislik: Istanbul-based mid-sized Turkish contractor focused on infrastructure and building projects. Comparable scale and similar competitive position for municipal tenders in Istanbul and surrounding regions.

Broad incumbents

• Rönesans Holding: Large Turkish construction and real estate conglomerate active in infrastructure, hospitals, and industrial facilities. Comparable on PPP-driven public infrastructure delivery model, though significantly larger and more diversified.
• Enka İnşaat: Turkey's largest publicly listed contractor with a much broader and more international portfolio (power plants, airports, retail). Relevant comparable for the construction model and Turkish public-sector contracting experience, but operates at materially larger scale.
