Summary
This study introduces a new construction management framework integrating CAD, BIM, immersive tech, and 3D Gaussian Splatting. It significantly reduces rework and speeds up reviews for complex projects.
Area of Science:
- Construction Management
- Digital Engineering
- Information Management
Background:
- Traditional construction management faces challenges with technical isolation and process inefficiencies.
- Whole-life-cycle model coordination is a key area needing improvement.
Purpose of the Study:
- To develop a comprehensive management framework for optimizing model coordination through technology integration.
- To address deficiencies in traditional construction project management.
Main Methods:
- Integrated CAD drawings, Building Information Modeling (BIM), immersive technology, and 3D Gaussian Splatting scanning.
- Implemented ISO 19650 standards for information management.
- Validated the framework using a hospital project case study with complex structural and MEP coordination.
Main Results:
- Achieved an approximate 22%-35% reduction in pipeline dismantling rates.
- Shortened review cycles for complex nodes by 40%.
- Significantly improved construction quality verification accuracy.
Conclusions:
- Technological synergies can overcome traditional management limitations in construction.
- The developed framework establishes a robust foundation for future engineering projects.
- Further research is needed to validate across diverse projects and assess long-term impacts.

For the construction of a storeroom using concrete masonry units, it's essential to align the dimensions of the structure with the actual sizes of the blocks and the intended mortar joints. On the site in question, there's a stockpile of concrete masonry blocks with a nominal size of eight by eight by sixteen inches, which are to be used in the construction of the storeroom.
The site engineer has laid out a plan for the storeroom with external dimensions of twelve feet in length and...

Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...
