The international engineering company CAI Interbudmontazh has confirmed its participation in the XXV International Exhibition and Conference "White City Ashgabat 2026" (WCA 2026) as a Gold Sponsor. The forum will take place on May 24–25, 2026, in Ashgabat.

About the Company

CAI Interbudmontazh is a Swiss engineering company (Canton of Zug) with over 30 years of experience in executing large-scale infrastructure projects across the CIS, Central Asia, Eastern Europe, the South Caucasus, the Middle East, and North Africa. The company has successfully completed over 150 projects as an EPC contractor, including those under FIDIC contracts.

The company specializes in underground infrastructure and complex engineering structures, including:

- Metro systems

- Transport and utility tunnels

- Hydraulic tunnels

- Drainage and collector systems

- Trunk pipelines

The company utilizes both open-cut methods and trenchless technologies, such as Tunnel Boring Machine (TBM) driving and microtunneling.

Today, CAI Interbudmontazh is actively operating in Turkmenistan, Kazakhstan, Uzbekistan, and Ukraine, maintaining partnerships with European equipment manufacturers, design institutes, and international financial institutions.

Key Areas of Activity

- Transport Infrastructure: Metro systems and stations, light rail transit (LRT), road and railway tunnels, bridges, and overpasses.

- Hydraulic Engineering: Hydroelectric power plant tunnels, main canals, dams, spillways, drainage systems, and flood protection.

- Urban Utilities: Collector and sewage treatment facilities, large-diameter utility tunnels, and microtunneling (DN 1600+) under active urban areas.

- Industrial Facilities: Turnkey plants and production complexes, oil and gas infrastructure, and grain elevator complexes.

- In-House Production: Reinforced concrete segments (tubbing) for tunnel lining, standard precast concrete products, and steel structures—ensuring quality control and schedule adherence on critical project phases.

- Design & Engineering: Subway stations, tunnels (transport, utility, hydraulic), and complex infrastructure projects aligned with international standards (FIDIC, Eurocode) and local regulatory frameworks.

Engineering Competence

CAI Interbudmontazh specializes in high-complexity projects, operating in weak and water-saturated soils, high seismicity zones, dense urban environments, and extreme climate conditions. The company owns a fleet of tunnel boring machines and possesses extensive experience in integrating European equipment (Herrenknecht, Robbins) with custom production and logistics solutions for projects in remote regions.

Project management is built on combining international contract models (FIDIC Red/Yellow/Silver Books, EPC Lump-Sum, EPC+F) with a deep knowledge of post-Soviet regulatory frameworks (ENiR, SSR, SNiP, SESN). This allows the company to serve as a vital link between the client, international financing bodies, and local supply chains.

Partnership with Turkmenistan

Since 2001, CAI Interbudmontazh has systematically contributed to the development of Turkmenistan's engineering and water management infrastructure. Key areas of cooperation include:

- Ashgabat's Underground Drainage and Collector System: A strategic project aimed at lowering groundwater levels, increasing the resilience of urban utilities, and strengthening the environmental security of the capital.

- Karakum River Basin Water Infrastructure: Modernization of main canals and water resource management systems to ensure sustainable water supply for the urban and agricultural sectors.

- Urban Utilities in Ashgabat and Regions: Large-diameter pipeline networks, partly executed using microtunneling methods to minimize the impact on the active urban environment.

Years of operation in Turkmenistan have provided the company with a profound understanding of the region's climatic, soil, and logistical characteristics, as well as the requirements of local clients and the priorities of the state modernization program.

Strategic Participation in the WCA 2026 Business Program

As part of the forum's business program, Vladimir Petruk, Managing Director of CAI Interbudmontazh, will speak at the Strategic Plenary Session titled "Shaping a Sustainable, Smart, and Globally Integrated Capital."

The session is dedicated to the long-term development of Ashgabat within the framework of Turkmenistan's National Modernization Strategy. The discussion will focus on integrating infrastructure, energy, and industrial projects, adopting modern approaches to urban planning, and ensuring environmental safety while creating a sustainable urban environment.

CAI Interbudmontazh aims to share its practical experience in executing complex underground and infrastructure projects in the region and discuss how international engineering expertise can be integrated into national development programs.

Openness to Cooperation

CAI Interbudmontazh views WCA 2026 as a platform for direct, professional dialogue. The company is open to collaboration across several key areas:

- With State Authorities and Municipalities of Turkmenistan: On implementing national programs for the modernization of urban infrastructure, transport systems, and underground utilities in the capital and regions.

- With International Equipment Manufacturers and Tech Partners: On localizing the supply of tunnel boring equipment, tunnel safety systems, building engineering systems, and solutions for smart cities and sustainable water management.

- With Design Institutes and Engineering Companies: On joint development of technical solutions for next-generation projects—ranging from subways to main collectors and hydraulic structures.

- With International Financial Institutions and Investors: On structuring EPC and EPC+F projects using recognized international contract models and quality management standards.

The company invites forum delegates and partners to meet during the business program to discuss specific projects, technical solutions, and partnership formats.

About the Role of the Forum

CAI Interbudmontazh's participation as a Gold Sponsor of WCA 2026 reflects its high regard for the Ashgabat Forum as a major regional platform for professional dialogue, investment cooperation, and practical project implementation. This year, the forum is expected to bring together over 700 delegates from more than 55 countries.
