For effective pre-construction process, engineers create a 4D building information model (BIM). However, the rich information associated with the creation of the 4D BIM leads to manual effort. Past studies explored methods that automatically generate construction schedules using 3D building models. However, no method properly utilized relationships between building elements to robustly generate 4D BIMs that are structural stable during installation. This research presents an approach to the automated generation of structurally stable construction sequences using a 3D BIM. Focusing on steel erection, we create a framework integrating a 3D BIM and algorithms to create a 4D BIM with detailed steel erection sequences of individual elements. This research explores an approach to a variation of static indeterminacy for each installation process of steel elements. The principle of this approach is based on the relationships among the nodes and the connections among steel elements, information about which is available to those involved in the project. For validation, we test a prototype software program using a BIM for a real-world construction project. The results indicate that the prototype utilizing the static indeterminacy variation could generate a large number of random sequences and successfully transforms them into stable sequences. This study establishes the foundational step of generating constructible sequences using structural information in BIM which is found to be more robust than previous approaches, and results of this study can lead to follow up studies for full automation such as automated analysis and optimization of the sequences.

为了进行有效的施工前过程，工程师创建了4D建筑信息模型（BIM）。但是，与创建4D BIM相关的丰富信息会导致手动操作。过去的研究探索了使用3D建筑模型自动生成施工进度表的方法。但是，没有一种方法能够正确利用建筑元素之间的关系来可靠地生成在安装过程中结构稳定的4D BIM。这项研究提出了一种使用3D BIM自动生成结构稳定的施工序列的方法。专注于钢架设，我们创建了一个框架，该框架集成了3D BIM和算法，以创建具有单个元素的详细钢架序列的4D BIM。这项研究探索了一种在钢构件的每个安装过程中改变静态不确定性的方法。这种方法的原理基于节点之间的关系以及钢元素之间的连接，有关这些信息可供项目中的相关人员使用。为了进行验证，我们使用BIM对一个实际的建筑项目测试了一个原型软件程序。结果表明，利用静态不确定性变异的原型可以生成大量随机序列，并将其成功转换为稳定序列。这项研究建立了使用BIM中的结构信息生成可构建序列的基础步骤，该信息比以前的方法更可靠，
