Case Study

Quang Trach 1 Chimney Project

The Quang Trạch I Power Plant is part of Vietnam’s national strategy to strengthen energy security and meet rising electricity demand. The facility comprises two ultra-supercritical coal-fired units with a combined capacity of 1,400 MW.

Balanced Engineering & Construction (BEC) was awarded the contract to construct the plant’s 230-metre environmental compliance chimney, a critical structure designed to manage emissions from the new generating units. Built on reclaimed coastal land, the chimney required precision engineering and safe high-rise execution under challenging site conditions.

Project Challenges

  • Reclaimed Coastal Land – The chimney foundation was constructed on reclaimed ground, requiring specialised geotechnical design to manage soil settlement, load distribution, and ensure long-term stability against coastal conditions.
  • Marine and Weather Exposure – Located within the Hòn La Economic Zone, the site is exposed to typhoons, high humidity, salt-laden air and wind speeds of 55 m/sec (3-second gusts). These conditions demanded robust structural engineering, careful construction practices and durable corrosion-resistant materials.

BEC's approach

The Quang Trạch 1 chimney was constructed using the slipform method, allowing for a continuous 24-hour pour of concrete to achieve a seamless 230-metre shaft.

Scope of work by BEC included:

  • Detailed design and engineering works
  • Pile-cap construction
  • Borosilicate block lining for long-term durability
  • AWL (Aircraft Warning Lights) system installation
  • Internal steel works
  • Protective coating and external painting
  • Electrical and lighting systems integrated throughout
  • Suppy and installation of rack-and-pinion access hoist
  • Lightning protection system

The BEC Advantage

The Quang Trạch I chimney was delivered safely, on time, and to specification, demonstrating BEC’s expertise in constructing one of Vietnam’s tallest industrial chimneys under challenging coastal conditions. The continuous 24-hour slipform casting showcased precision engineering, while borosilicate-lined flues provided long-term durability and emissions compliance.

 

By integrating civil, mechanical, and electrical systems, including steel platforms, coatings, lighting, and hoist provisions, BEC handed over a fully operational structure that strengthens the reliability of Quang Trạch 1 and supports Vietnam’s goal of securing stable energy generation.
