NPS® Top-Down
The single-span NPS® Top-Down system exclusively employs self-supporting NPS® beams, placed on perimeter diaphragms. In this way, the beams perform both the function of a temporary strut, counteracting wall deformation, and that of a permanent load-bearing element. This solution eliminates the need for temporary struts and allows for a high speed of construction.
Advantages
- Total self-supporting beams
- Containment of excavation within the site perimeter
- Speed of execution
- Possibility of visible beams without additional finishing
Areas of application
Common application areas include:
- underground car parks
- infrastructure such as underground lines
- large buildings with underground floors

Sustainability
Assembly
One of the most innovative features of this solution is the possibility of carrying out the excavation and structure installation phases simultaneously. This means that while excavation is taking place, beams are immediately placed to support the perimeter bulkheads, guaranteeing the stability of the excavation itself. This mode of operation, referred to as ‘covered excavation’, allows construction to proceed safely and efficiently, reducing construction time and minimising impact on the surroundings.
References
For decades, the NPS® Top-Down system has been successfully used in many projects, from residential buildings to car parks and infrastructure.
The reason? The solution gives the possibility to carry out the excavation and laying phases of the structures simultaneously, guaranteeing speed and high construction flexibility. In addition, the general planner can count on Tecnostrutture’s engineering support for more efficient and simpler construction.
