Automated compatibility checking of prefabricated components using 3D as-built models and BIM

There have been recent efforts to use reality capture technologies to perform remote quality control in construction. However, there is a lack of research efforts in detecting construction incompatibilities in modular construction using reality capture technologies. The construction incompatibilities in modular construction often cause reworks and delays in the project schedule. To address this issue, this paper presents a general compatibility analysis method that propose scanning the modules in manufacturing plant and construction site, and check module-to-module compatibility remotely, prior to the shipment and installation. This study provides three sample module-to-module compatibility scenarios to validate the proposed compatibility analysis. The case study results show that the compatibility analysis method was able to identify the compatibility issues with high accuracy. Lastly, the compatibility analysis method was validated in terms of accuracy and time performance in six scenarios that was defined on the modules.

Intelligent Compaction: An Improved Quality Monitoring and Control of Asphalt Pavement Construction Technology

In transport sector, improving the quality of road construction plays a crucial role in developing a more sustainable and cost-effective infrastructure network. Intelligent Compaction (IC) has been actively studied as a novel and promising technology for quality monitoring and control in asphalt road construction. However, a successful application of IC in pavement construction is still bothered by its accuracy and stability in quality evaluation. This paper proposed AICV– Acceleration Intelligent Compaction Value, a new evaluation index for harmonic intelligent compaction quality evaluation and with a higher accuracy than the frequently used index CMV– Compaction Measurement Value. In order to optimize the evaluation of the compaction quality uniformity of asphalt pavement, the <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$3\sigma $ </tex-math></inline-formula> of Normal Distribution is adopted to estimate the compaction uniformity. The statistical analyses of the field measurement data show that, both CMV and AICV are applicable to evaluate the uniformity of compaction quality. However, the dispersion degree of AICV is far less than that of CMV, indicating that AICV is more stable as an index for compaction quality evaluation. By using spatial statistics, the spatial correlation distance of the compaction quality is further obtained, which gives to an assessment of the influence range of intelligent roller. Overall, the study provides a basis for improving the quality control of asphalt pavement construction by means of more delicate monitoring of the compaction process.

Detection of setting time during cement hydration using ground penetrating radar

The setting time of concrete needs to be detected to ensure the construction quality control. This research provides a new non-contact, nondestructive remote sensing detection method based on ground penetrating radar (GPR) for monitoring cement setting time. The moisture content of cement paste decreases during hydration, resulting in a change of its dielectric constant. Furthermore, dielectric permittivity affects the wave velocity and echo intensity of electromagnetic waves. Based on these characteristics, this paper utilizes GPR to measure the moisture content of cement paste in terms of changing dielectric permittivity, and then assess the setting time depending on the link between the moisture content and setting state of the cement paste. To detect an object smaller than one-wavelength, the full-waveform inversion is used to analyze the GPR echo data instead of the traditional velocity inversion measurement. The positive correlation between the reflection coefficient and dielectric constant is verified by both simulations and experiments. The experiment results accurately determine the initial and final setting time of cement paste, compared with the Vicat apparatus test. The method of GPR monitoring cement paste setting time based on full-waveform inversion theory can solve the quality control problems of concrete leveling automation and concrete layered construction automation.

Analysis on Key Points of Quality Management of Housing Construction Engineering Supervision Site

In the development of the construction industry at this stage, with the acceleration of urbanization and the progress of construction technology, the scale and technicality of housing construction projects at this stage continue to improve, which has brought great challenges to the existing construction personnel. Staff members are easy to make mistakes in the operation link, affecting the quality of the building. Therefore, relevant personnel are required to carry out on-site supervision for construction projects and carry out construction quality control through various means. However, the construction project involves a wide range, and there are still some problems in quality management. This paper starts with the supervision site of housing construction project, and discusses the key points of quality management.

Discussion on Construction Quality Control Measures of Building Decoration Engineering

Building decoration engineering is the secondary creation and improvement of the main structure of the building. Construction decoration engineering construction is the process of decoration design scheme into decoration entity. Its construction quality is not only constrained by the customer needs and the design scheme, but also needs to meet the relevant requirements of the national quality standards for building decoration engineering. The construction quality of building decoration project is affected by many factors. Starting from the definition and value of architectural decoration engineering, this paper interprets the quality requirements of architectural decoration engineering, and seeks for the elements affecting the quality of the project, as well as the correlation between the influencing elements. Then explore the quality control measures in the project construction, and elaborate from the perspective of the construction personnel management, construction technology improvement, design planning, construction planning and scientific management in the construction.
