Mechanical and electrical deepening design

In some large-scale construction projects, due to the complex spatial layout and numerous systems, high requirements are placed on the layout of equipment pipelines. Collisions between equipment pipelines or between pipelines and structural components are prone to occur, causing difficulties in construction and inability to meet the indoor net height of the building, resulting in secondary construction and increasing project costs. Based on BIM technology, professional models such as architecture, structure, and electromechanical can be integrated, and the comprehensive model can be imported into relevant software for collision inspection according to professional requirements and warning requirements. Based on the collision report results, pipelines can be adjusted and avoided, and equipment and pipelines can be comprehensively arranged to discover problems before the actual project starts.

Steel structure deepening design

In the deepening design of steel structures, BIM technology is used for three-dimensional modeling to visually simulate the spatial layout of steel structure components. By conducting collision verification in advance, the scheme can be optimized to effectively solve design defects in construction drawings, improve construction quality, reduce later modifications and changes, avoid waste of manpower and material resources, and achieve cost reduction and efficiency improvement. Specifically, the use of BIM models for steel structures can be demonstrated as follows: Before processing steel structures, optimize and adjust the construction methods, process methods, and process arrangements of specific steel components and nodes, effectively guide the manufacturing workers adopt reasonable and effective process processing, improve construction quality and efficiency, and reduce construction difficulty and risks. In addition, during the installation process of steel components at the construction site, precise verification and positioning of the lifting weight and installation operation space of each steel component are carried out through steel structure BIM model data, creating value for lifting construction in complex and special environments.

Multi-professional coordination

The organization and coordination among various professional subcontractors are the key to the smooth implementation of construction projects and the guarantee for improving construction progress, and their importance is beyond doubt. At present, due to factors such as construction sites, professional coordination, and technical differences, there is a lack of coordination and cooperation among various specialties such as HVAC, water supply and drainage, fire protection, and strong and weak electricity. This inevitably leads to many local, implicit, and unforeseeable problems, which can easily cause poor and overlapping performance of various specialties in certain horizontal positions of the building, making it difficult to operate according to the construction drawings. Through the 4D construction management of BIM technology, pre- simulation of the construction process can be carried out, and measures such as coordinating the vision of various specialties based on problems can be taken to reduce coordination problems caused by technical and communication errors, greatly reduce rework, and save construction costs.

 

Site layout optimization

With the development of the construction industry, the requirements for the organization and coordination of projects are becoming higher and higher. The complexity of the surrounding environment of projects often leads to problems such as narrow site, deep foundation pits, close distance to surrounding buildings, high requirements for green construction and safe and civilized construction. In addition, sometimes the construction site has a large working area, and there are differences in height between different zones of construction. The site is complex and variable, which can easily cause continuous changes in the site layout, And the frequency of changes is increasing, which brings difficulties to the reasonable layout of the project site. The emergence of BIM technology provides a good way for layout work. After the construction site model and building model are created by applying the resources of the project site equipment and facility family, the actual environment around the project and the site is linked to the model in the form of data information. A three-dimensional layout of the site is established, and by referring to the engineering schedule, the on-site situation at each stage can be vividly and intuitively simulated, Flexibly carry out on-site layout to achieve reasonable and efficient on-site layout.

The combination of GIS technology and BIM

Indoor navigation

Indoor navigation is one of the prominent features of BIM plus GIS applications. Traditional navigation relies on GIS technology, but its disadvantage is limited to outdoor environments. The integration of GIS and BIM technology can compensate for the indoor blind spots of GIS technology and expand the navigation application of GIS technology to indoor environments.

Municipal sector

If the establishment of a three-dimensional city only relies on GIS technology, whether through photography or radar scanning, it requires a lot of work from post production personnel to build models. The model lacks architectural information and cannot query and analyze the indoor architectural environment. The integration with BIM technology first establishes a three-dimensional data model through BIM technology, and then integrates and shares it with GIS technology to achieve the establishment of a three-dimensional model of urban buildings and the surrounding environment which Improved the accuracy and query ability of the model.

3d visualization

By directly utilizing 3D models and combining with external software, we provide real-time 3D support to Party A, providing customers with more intuitive real-time 3D images, and facilitating their understanding of construction progress and internal space usage. BIM technology makes the description of professional air ducts, water pipes, and air conditioning equipment popular and visual in 3D, providing real 3D models for owners at various stages. This enables professionals and non professionals such as owners to have a clear understanding of the overall effect of the building, make clearer and more efficient judgments on whether project requirements are met, and make more accurate decisions. It can effectively reduce project changes and save investment.

Post cooperation

Combined with cloud technology, BIM design can provide real-time 3D construction management and technical support for on-site construction. Real-time communication with other device terminals can be achieved by handheld mobile devices, which bringing convenience to construction management.

Component assembly

By utilizing BIM technology for virtual assembly of components, construction units can detect potential hazards as early as possible, thereby saving time and cost for the entire project and reducing resource waste. On the basis of deepening BIM design, the layout of component planes is completed first, and then the automatic and rapid modeling of the component is realized by using the idea of parametric design and combining the information in the component library.  Then, the automatic verification function of BIM is used to verify the design errors, and the completed components are pre-assembled to test their correctness and constructability.

Accurate calculation

BIM technology can provide more detailed three-dimensional information components than traditional methods, making it more accurate for engineering investment control. Under the premise of meeting the functional requirements, BIM building performance analysis has found a balance between indoor comfort, building energy consumption, and environmental protection; An efficient work platform also strictly controls the selection of materials and systems, and effectively calculates and controls construction and operational costs. The material expression and properties include the material, transparency, and color, which are interrelated and easy to modify.

Green and energy-saving analysis

The 3D information model provided by BIM technology makes effective support for the construction of green buildings. Combined with relevant green energy-saving software, projects with limited land and many surrounding restrictions can optimize building design through preliminary design analysis, effectively reducing building energy consumption. Especially in complex and irregular public buildings, the effect is outstanding. During the design phase,Ecotect software based on BIM platform can simulate a lot of quantify parameters of the environmental effects of various schemes ,such as light environment, air quality, ventilation, temperature, radiation, energy consumption, etc.
