The construction industry plays a substantial role in the economic prosperity and growth of all other sectors in any country. To foster the economic sustainability of a construction project, it is crucial to evaluate all the associated current and future project costs. To address the current and future related costs to a project, life cycle cost analysis (LCCA) is the most sophisticated economic approach. However, traditionally, LCCA is performed manually, and thus, limited implementation is observed due to time-consuming and tedious steps. To address the issue, this current research attempts to automate the LCCA process and develop an advanced algorithm for LCCA with building information modelling (BIM) integration. Following the algorithm, an LCCA-BIM tool is developed using C# programming language that automates the extraction of bills of quantities and facilitates the incorporation of cost data associated with a project with the LCCA parameter to determine life cycle cost. A case study was performed that validated the effectiveness of the algorithm in performing LCCA for a project. Integrating LCCA with BIM streamlines and automates the economic evaluation process and offers a robust framework for future advancement in LCCA implementation. The application leads to enhanced decision-making and encourages sustainability in building projects by eradicating barriers to retrieving and automating the LCCA.

In order to improve the efficiency and accuracy of the modeling and design work of the sluice gate project, this paper proposes an automatic generation template of the sluice gate project with customized semantics and project layout scheme, aiming at realizing the rapid assembling of all kinds of components of the sluice gate project. In the construction process, this paper first starts from basic parametric modeling and proposes constraints as the basis of modeling. Subsequently, a template library framework is developed based on the constraints to ensure that the generated templates have a high degree of standardization and consistency. Finally, an efficient and flexible template library is successfully constructed by using the customized classes and functions of revit api, which provides powerful technical support for the modeling and design work of sluice gate engineering. This achievement helps to promote the informationization and intelligent development of the water conservancy engineering industry, and its versatility and scalability also make it have a wide range of application prospects in other water conservancy engineering fields.

The current BIM-based PV system design process largely depends on transferring a model to special PV simulation software. Critical geometric information is often lost during this process. An automatic PV system design and management tool was developed, which fully integrates the existing and future information of PV systems in a building information modeling (BIM) platform. This tool, PV Link, first analyzes the solar radiation on a building geometry. Then, it automatically places the PV panel based on the solar analysis and user-defined variables like PV size, roof geometry, and rooftop equipment. Finally, the solar radiation on each panel and the electricity produced are calculated and results shown in a building information model. Several case studies show it can design systems efficiently. With the information-rich BIM model, real-time analysis and management of the PVs are feasible to maintain the performance of the PV system in operation. In response to an issue raised by one of the reviewers, there is an additional discussion of the nature of science and applied science.
