ALKATAŞ CONSTRUCTION

What ALKATAŞ CONSTRUCTION does

ALKATAŞ İNŞAAT VE TAAHHÜT A.Ş. (Alkataş Construction) is a privately held Turkish general contractor founded in 2001 and headquartered in Beykoz, Istanbul. The company delivers large-scale public infrastructure across four integrated service lines: (1) wastewater treatment and water infrastructure (advanced biological N-P removal, Membrane Bioreactor systems, UV disinfection, biogas energy recovery), (2) superstructure construction for public-sector clients (stadiums, congress centers, government service buildings — including LEED GOLD-certified structures), (3) post-construction operations and facility management, and (4) energy facilities spanning thermal, biogas, and solar PV generation. Its portfolio comprises 222 completed projects, 2.2 million m² of constructed area, and 3.1 million m³/day of operational wastewater treatment capacity.

The firm's core technology stack is conventional civil and environmental engineering rather than software-driven: differentiation rests on FIDIC Design-Build contract execution, ISO 9001:2015 quality certification, LEED delivery capability, and the ability to bundle treatment, superstructure, and energy scopes under a single procurement. Revenue is generated through competitive bidding on government tenders, with two distinct streams — one-time construction contracts and 1–5 year managed operations agreements — yielding a project-based, milestone-driven cash flow profile rather than recurring SaaS-style revenue. The customer base is overwhelmingly public sector: İSKİ, MUSKİ, BUSKİ, SASKİ, the Turkish Ministry of Youth and Sports, Toplu Konut İdaresi, and municipal authorities such as Üsküdar and Kocaeli, with ŞişeCam (Mersin glass factory, 2022) the only named private industrial client.

The go-to-market is exclusively direct enterprise field sales targeting public procurement. Geographic reach extends beyond Turkey into Azerbaijan, Ukraine (Mykolaiv WWTP, ongoing since 2021), Moldova (Cahul WWTP), Uzbekistan, and the Maldives via project offices, supported by an Ankara regional office. Distribution relies on tender participation and track-record-driven pre-qualification rather than intermediated channels.
