Abstract:
The retrieval of historical buildings in HBIM database faces three main issues: 1) the absence of universal rules for determining the similarity between buildings; 2) the neglect of historical and cultural information inherent to the buildings themselves; 3) most queries rely on keywords, which imposes limitations of available information. Addressing these challenges, this paper introduces a multimodal retrieval approach for historical buildings. Users can retrieve a list of buildings matching their input features, whether through images or natural language text data. For image-based building retrieval, the "dino_vit16" model is employed for feature extraction, achieving a retrieval accuracy of 90.08% with the proposed image-building retrieval method. For text-based building retrieval, a connection between images and text is established through the CLIP model. The study explores the values of image-text similarity and text similarity weights, selecting m=0.6 and n=0.4 as the optimal configuration for these weights. Experimental results have shown that the proposed text-based architectural retrieval algorithm performs best when the query statement contains a specific visual feature, and it performs worst when the query statement describes a particular function and architectural style. However, when the query statement includes four or more mixed features that accurately describe the fundamental appearance of a building, it can accurately retrieve buildings that meet the criteria.

Abstract:
To address the issues of aging structures and suboptimal thermal performance of envelope structures in existing rural housing in Hubei, which lead to increased energy consumption and poor indoor thermal environments, there is an urgent need to renovate these envelope structures. This study focuses on the renovation of envelope structures in a typical rural house in Hubei, utilizing the energy consumption simulation software Ecotect to quantitatively analyze the energy-saving efficiency of various renovation plans. Using the entropy method and multi-factor orthogonal experiments, 16 representative renovation plans were analyzed to identify those that balance energy efficiency and economic viability. The results indicate that the effectiveness of single-factor renovation plans, in descending order, is roof renovation > door and window renovation > exterior wall renovation. In the multi-factor combined renovation plan selection based on the entropy method, the weights of energy-saving rate, initial investment in energy-saving renovation, energy-saving renovation benefits, static payback period, and Net Present Value (NPV) are 0.2, 0.26, 0.21, 0.14, and 0.19, respectively. This study provides a new approach for energy-saving renovation of existing rural houses in Hubei and offers valuable insights for selecting optimal renovation plans.

Abstract:
Floor slab cutting is fundamentally a polygon clipping problem. However, existing algorithms involve complex data structures and implementation processes, making them difficult to apply broadly in practice. While some mainstream BIM software on the market offer floor slab cutting functions, most can only handle regular slabs and cannot address complex boundaries such as curves and concave polygons. This paper presents two new methods for cutting floor slabs in Revit. The first method is based on geometric calculations, which solves the new profile after cutting by sorting collision points between the cutting lines and the original slab contour lines. This method is applicable to BIM software platforms beyond Revit and has a broad range of applicability. The second method, based on the concept of dimensional elevation, transforms the two-dimensional problem into a three-dimensional one and utilizes Revit's open 3D solid Boolean operation interface for solving. Both methods avoid complex data structures and are easy to implement, providing valuable references for developers involved in secondary development.

Abstract:
As the construction industry undergoes digital transformation, BIM technology has emerged as a critical development direction. Within BIM technology, digital-analog separation is a technology that distinguishes geometric model information from non-geometric model information. This separation enables lightweight component loading, reduces repetitive modeling workload, and facilitates cross-model reuse, offering significant application value. This paper discusses the implementation methods and application scenarios of digital-analog separation technology. By dividing the geometric model and the non-geometric model into separate data files or structures, a comprehensive digital representation of the building model is achieved. Geometric models are utilized for architectural form representation, structural analysis, and construction simulation, whereas non-geometric models are employed for attribute information management, construction organization design, and quantity calculations. This method enhances data management efficiency and accuracy, minimizes data redundancy and inconsistencies, and provides robust support for the digital transformation of the construction industry.

Abstract:
The EPC contract mode in hospital construction often leads to challenges such as overestimation and disjointed transitions between construction and operational maintenance phases. This study investigates the integration of operation management capabilities, focusing on improving connections between the general contractor's construction phase and the pre-operation phase of the hospital. Through quota design, continuous operational demands, and detailed management strategies, the study enhances management efficiency under the EPC contract mode. Emphasis is placed on the application of BIM technology in optimizing hospital building pipe networks and analyzing the net heights of public areas. The research proposes a refined management approach to connect various hospital departments effectively, providing valuable insights for managing medical buildings under the general contract mode.

Abstract:
The EPC general contracting management mode encompasses the entire process of design, procurement, construction, and optimization, among other phases. Given the long cycle, diverse specialties, high precision requirements, and the management side's lack of experience associated with EPC projects, achieving ideal outcomes can be challenging. In particular, the integration between design and construction is notably difficult, complicating the maximization of benefits. This study explores how BIM technology, with its professional data support and capabilities for visual and analog simulations, can enhance key aspects of construction drawing design changes, budget preparation, and construction processes. By leveraging digital results for reliable analysis and decision-making, the study aims to improve the standardization of EPC project products, management, and processes, thereby advancing the digital transformation of the construction industry.

Abstract:
This study addresses the issues of low efficiency and accuracy in the automatic matching of aluminum formwork, which are attributed to the large volume of information in BIM structural models, non-standard modeling practices, and unclear rule constraints. The research focuses on the structural model used during the design phase of aluminum formwork matching. It first analyzes the effective spatial and component information within the model and then establishes corresponding rules for model modeling, classification coding, and collision avoidance strategies. By selecting an engineering case and developing a test plug-in for information extraction and automatic matching, the study validates the effectiveness of the model information and the feasibility of the proposed rules. The results demonstrate that the proposed method significantly enhances the efficiency of BIM automatic matching for aluminum formwork and provides valuable insights and support for related BIM structural model research.
