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.
