The Structural Schematic Design Phase marks a critical progression from conceptual intent to a coordinated structural framework that defines the building’s load-bearing systems, layout, and overall stability. In this phase, structural engineers develop schematic-level framing plans, foundation layouts, and lateral load-resisting systems that are fully aligned with the architectural design and major MEP requirements. The objective is to transform general structural strategies—identified during the concept stage—into tangible structural systems that are spatially coordinated, code-compliant, and constructible.

This phase includes selecting appropriate structural systems (e.g., reinforced concrete, structural steel, post-tensioned slabs), verifying framing continuity, and initiating analytical modeling to preliminarily size members such as beams, columns, walls, and slabs. Substructure elements are also defined based on geotechnical data and loading assumptions.

Close coordination with architectural and MEP teams is essential to ensure compatibility with core layouts, equipment zones, floor penetrations, and service integration. The outcome of this phase includes schematic structural drawings, narrative reports, and quantity estimates that form the basis for design development, early cost planning, and risk mitigation.

Overall, the schematic design phase establishes the structural system’s logic, clarity, and efficiency—setting the foundation for detailed analysis, constructability planning, and multidisciplinary alignment in subsequent phases.
