What Tolay Engineering & Construction does
Tolay Engineering & Construction (Tolay Mühendislik ve İnşaat) is a Turkish EPC contractor headquartered in Istanbul that delivers turnkey Pre-Engineered Building (PEB) steel structure solutions for industrial, commercial, government, and cultural-sector clients. Founded in 2008 and operating across more than 13 countries including Turkey, Turkmenistan, Mongolia, Ghana, Senegal, Pakistan, Oman, Uzbekistan, Sudan, Saudi Arabia, Uruguay, Belize, and Benin, the company manages the full project lifecycle from permitting and architectural/structural design through infrastructure, superstructure, mechanical-electrical systems, fire safety, and occupancy procedures under single-contract delivery. Core service lines span design, construction, EPC, steel manufacture, procurement services, and project development, with the company's own website highlighting recent portfolio assets such as the Forum Istanbul Shopping Mall (495,000 sqm), the 75,000 sqm Erluks Logistics facility, and the 193,000 sqm Turkmenistan Aquapark.
The company's underlying technology centers on factory-fabricated PEB steel components with bolted-only on-site connections, robotic welding for consistent structural quality, galvanized secondary members for corrosion resistance, insulated roof and wall panel systems, seismic-safe design under the Turkish Seismic Code, and specialty techniques such as FRP carbon fiber reinforcement for historical retrofit. This stack delivers approximately 30% cost reduction versus prefabricated concrete, approximately 60% faster installation versus conventional methods, and industrial-facility pricing of approximately 300 USD/m². Tolay monetizes primarily through one-time EPC contracts and steel construction services, supplemented by professional design/engineering fees, materials procurement, and select project-development activities including the Forest Island Mongolia residential project.
The firm serves enterprise and government clients through direct business development, client referrals, and international tender participation, with named logos spanning OLAM, Alapala Makine, Okyanus Grup, Türkmen Gaz Bakanlığı, the World Bank, Vodafone, and Marriot. With only six core employees disclosed despite the project footprint, Tolay operates a lean management model that subcontracts execution labor. Operating status is active, with website and project updates extending into 2025-2026 and no public listing, parent company, or funding rounds disclosed.
