TYPICAL APPLICATIONS

  • High-rise buildings

  • Deep urban excavations

  • Multi-level underground parking structures

  • Commercial and mixed-use developments

  • Buildings with multiple basement levels

  • Projects constructed close to property lines

  • Sites where external anchors are restricted or undesirable

  • Projects requiring accelerated construction schedules

  • Dense urban sites with limited construction space

  • Large developments where simultaneous above-grade and below-grade construction can provide significant schedule advantages

SFS® UP-DOWN BUILDING SYSTEM

FROM TEMPORARY TO PERMANENT

The SFS® UP-DOWN philosophy is based on directing construction resources toward structural elements that remain useful throughout the life of the building. Permanent retaining walls, columns, beams and floor diaphragms contribute during construction and continue performing as part of the completed structure.

The objective is not merely to support construction — it is to build the final structure from the very beginning.

ACCELERATES CONSTRUCTION BY INTEGRATING "UP-DOWN" BUILDING OPERATIONS

WHAT IS THE SFS® UP-DOWN BUILDING SYSTEM?

The SFS® UP-DOWN Building System is a proprietary structural construction methodology that integrates permanent retaining walls, permanent floor systems and structural framing into a coordinated construction process capable of advancing simultaneously above and below grade.

Rather than relying extensively on temporary shoring, anchors, reshoring, formwork and bracing, the system is designed so that many structural elements introduced during construction remain as permanent components of the completed building.

KEY TECHNICAL ADVANTAGES:

  • Allows simultaneous construction above and below grade

  • Integrates permanent retaining walls, floor systems and structural framing

  • Reduces dependency on temporary retaining systems

  • Reduces or eliminates external tie-back anchors

  • Reduces temporary shoring and reshoring

  • Reduces temporary formwork and bracing

  • Permanent structural elements begin working from early construction stages

  • Permanent floor diaphragms contribute to excavation stability and final structural performance

  • Maximizes the use of permanent structural components instead of disposable temporary works

  • Can significantly shorten the overall construction schedule

  • Can reduce site congestion and improve construction logistics

  • Uses conventional structural materials and established engineering principles

WHY IS THE SFS® UP-DOWN SYSTEM DIFFERENT?

The SFS® UP-DOWN Construction Process is not simply a different construction sequence. It is a fundamentally different way of organizing structural construction.

Conventional construction often depends on temporary retaining systems, anchors, shoring, reshoring, formwork, bracing and access structures that are later removed, abandoned or discarded. The SFS® UP-DOWN System reduces this dependency by integrating permanent structural elements into the construction process from the earliest stages.

Permanent retaining walls, columns, beams and floor diaphragms contribute during construction and continue performing as part of the completed building. In this way, more of the project investment is directed toward the final structure rather than temporary works.

The SFS® UP-DOWN Building System is particularly well suited for complex urban projects where excavation depth, property-line restrictions, limited site access and construction schedule are critical factors. By coordinating permanent underground and above-grade structural work, the system can significantly improve overall construction efficiency.
