[The Landmark Journey Of Bachy Soletanche Vietnam] – Journey No. 6: LANDMARK 81

 

Beneath the striking beauty and dazzling skyline of Vietnam’s tallest tower lies an entirely different world – a 90-meter-deep underground realm where Bachy Soletanche Vietnam laid the very first foundations for a project of international stature.

Most people only see the brilliance above ground, but the true beginning happens beneath it where every meter of soil is controlled, every steel cage is precisely positioned, and every barrette is installed within the allowed tolerance.

Let’s journey into the world only those who built it have truly witnessed where every meter of depth holds a story, every reinforcement cage marks a milestone, and from which we understand why Landmark 81 is not just the tallest tower in Vietnam but also a symbol of engineering pride and human determination.

 

 Landmark 81: 461.2 m – Top 20 tallest buildings worldwide at completion; currently ranked 15th globally.

 Test Piles Package: 04/2015 – 04/2015

• Shaft grouted barrette: 1.0 m × 2.8 m – 80 m deep

• Plain barrette: 1.0 m × 2.8 m – 85 m deep

 Mass Piles Package: 06/2015 – 09/2015

• 28 shaft grouted barrettes – 1.2 m × 2.8 m – 85 m deep

• 31 standard barrettes – 1.2 m × 2.8 m – 85 – 90 m deep

• 84 standard barrettes – 1.0 m × 2.8 m – 85 – 90 m deep

• Verticality control of nearly 100 meters with deviations tighter than national standards.

• Shaft grouting technology applied to enhance shaft friction capacity.

• Continuous concrete pouring for hours.

• Strict slurry control in complex geological conditions near the river.

• Advanced O-cell load testing combined with top reaction.

This is a project that every Bachy Soletanche Vietnam engineer speaks of with pride. It wasn’t just construction, it was engineering at its most demanding and most real.

Landmark 81 stands tall against wind, load, and time because beneath it lies a 90-meter-deep foundation built with our full strength, expertise, and commitment.

 People often look up at the 81 floors above… but we are proudest of the 90 meters beneath.

 If you stood at the foot of Landmark 81 today, what do you imagine lies 90 meters beneath your feet?

 The power of hundreds of massive barrette piles?

 Vietnam’s leading foundation engineering technologies?

 Or the unwavering determination of those who worked tirelessly below ground?
