Case study – Sky Tower, a Bucharest landmark where long-term monitoring certifies safety in building operation

Sky Tower, the tallest building in Romania, is a complex construction where challenges do not disappear once the works are completed. Stability must be maintained against extreme weather conditions, seismic movements, and permanent loads. Any ignored structural displacement or uncontrolled settlement can lead to major problems and high repair costs.

For projects of such scale, it is important to monitor both the construction during execution and the surrounding buildings.

Sky Tower is 137 meters tall and has 37 floors, built from reinforced concrete for seismic resistance. High-speed elevators and a solar-protected façade complete a modern technical package. The building has obtained international certifications such as SHORE Platinum, LEED Platinum, and DGNB Gold, confirming the project’s quality, safety, and sustainability. It is almost fully occupied, attracting top tenants and increasing the value of the Floreasca area.

Long-term safety is supported by data obtained through structural health monitoring. This process involves periodic measurements that detect any changes in the structure. Settlements, displacements, and the overall behavior of the building are analyzed against the design parameters. Even minor deviations can indicate the need for preventive interventions before they become costly.

These measurements prevent incidents and accidents, provide a complete view of potential settlements or tilts, reduce damage, and protect neighboring structures from negative effects.

Xplorate Group carried out the structural health monitoring services for Sky Tower. We performed periodic measurements, analyzed the data, and compiled the results into clear reports that are easy for the building’s management team to use. This monitoring provided a solid foundation for making decisions about long-term maintenance and safety.

Through this process, you gain real information about the building’s behavior over time and can intervene before a problem becomes costly. You reduce the risk of damage, maintain safety, and protect the value of your investment. For a property owner or manager, these benefits mean fewer unplanned interventions and better control over the maintenance budget.

For this project, we used a Trimble DiNi 03 level and Invar staff, handled by a team of three land surveyors with experience in engineer surveying and in performing such measurements.

If you manage an office building, commercial space, or residential complex, our monitoring service provides:

  • Monitoring of settlements and structural displacements with high-performance equipment

  • Early detection of changes that may affect building stability

  • Clear and periodic reports for evaluating the condition of the structure

  • Support in making decisions about maintenance and repair work

  • Availability for additional inspections after seismic events or major interventions

In the case of Sky Tower, structural health monitoring maintained control over safety parameters. Repeated measurements formed the basis for designers’ reports, allowing them to conclude whether settlements were within acceptable limits, eliminating the risk of costly, unplanned interventions.

When data is up to date and correctly interpreted, management becomes simpler, and the property’s market value is protected. The direct benefit is reduced risk and optimized maintenance budgets. Sky Tower remains an example of a project supported by topographic and geodetic expertise and careful management, where continuous monitoring brings clarity, safety, and confidence.

By choosing constant monitoring through structural health monitoring (UCC), you turn every project into a safe, stable investment ready to maintain its value over time.
