What Is Included in a Structural Calculations Package?

A structural calculations package is a key engineering deliverable that explains how a building is designed to resist applicable loads and meet code requirements. For modular projects, it is often an essential part of permitting, plan review, and project coordination.
The package typically includes design criteria such as building code, project location, design loads, and material assumptions. It also documents how structural members and systems are evaluated for gravity, wind, seismic, and other applicable forces. Common contents include member checks, connection calculations, reaction summaries, and framing analysis.
For modular structures, the scope may also include lifting, transport, temporary support, and module bearing conditions. These added requirements are important because the structure must perform not only in final use, but also during handling and installation.
A well-prepared calculations package helps organize the structural design into a clear, reviewable, and permit-ready format. It supports code compliance while improving coordination between engineering, drawings, fabrication, and construction.
