Market Concentration in Construction Tenders in West Papua

This study aims to determine the level of market concentration in construction work tenders in West Papua and to investigate the correlation between the market concentration index and the average participation in tenders, the number of work packages, and average tender savings. West Papua has privileges in procurement and has special autonomy funds for development. The study uses tender data from 2018-2022 and employs the Herfindahl-Hirschman Index (HHI) and Concentration Ratio 4 (CR4) to calculate market concentration. The results indicate that, based on HHI, the market concentration in the building construction and civil engineering subsectors is generally low, except for civil engineering in 2022. However, based on CR4, the market concentration in the building construction subsector is moderate, and in the civil engineering subsector, it is low, except for 2018. Moreover, there is a negative correlation between the number of packages and average participants, as well as between the number of packages and CR4 values. The findings of this study can be useful for construction providers to understand the competition in tenders and assist the government in developing competitive procurement strategies. Future research can investigate the economic benefits of local West Papua businesses when market concentration is low.

Influence of plan configuration on low frequency vibroacoustic behaviour of floating floor with low natural frequency

The reduction of low frequency structure-borne sound transmission through floors is a highly demanding work in building construction engineering. The floating floor system with low natural frequency (FFLN) is considered as a practical method to reduce the low frequency transmission without changing structural design. An important aspect of the FFLN is how the low frequency performance is affected by the plan configuration. Researchers have questioned the differences in the low frequency behavior of the FFLN observed in various geometric configurations of the plan regarding this issue. This paper presents the full-scale experimental data for the vibroacoustic behaviors of a FFLN with different plan configurations. The experimental data are analyzed with theoretical considerations to investigate the influence of plan configuration on the low frequency impact sound response. The results of the analysis indicate that both the structural shape and dimension may affect the variation in low frequency impact sound due to differences in structural-acoustic modal coupling.

Numerical Simulation of Impact Caused by Construction of High-Rise Building upon Adjacent Tunnels

In this study, stress deformation of Qingdao Jiaozhou Bay undersea tunnel terminal during high-rise building construction engineering was evaluated by real 3D numerical modeling using Midas software. The simulations were performed during high-rise building foundation pit blocks, stratified excavation unloading, and loading the whole building construction on adjacent existing tunnel. The influence of the whole process through tunnel convergence, tunnel vertical displacement and horizontal displacement, as well as deformation curvature changes of additional stress and lining were used to evaluate the tunnel safety. The results showed that excavation at depth of 6 m, the whole process of high-rise building construction on adjacent tunnel deformation was conform to requirements of control. As building load deformation reduced near tunnel ceiling, one side of foundation pit became bigger and far away from side of foundation pit but did not return to front of foundation pit excavation tunnel state. The construction load of adjacent tunnel excavation generated small additional stress with overall design no more than tunnel load values. Overall, the tunnel was in safe working conditions and the proposed research provide certain guidance and reference for similar projects.

Also other amelioration measures were implemented. The article at first briefly introduces the method of siphon drains. The main part is devoted to model locality and description of the drainage.

Virtual water accounting for a building construction engineering project with nine sub-projects: a case in E-town, Beijing

Virtual water consumption accounting for an entire building construction engineering project including nine sub-projects is presented in this study to reveal the full picture of water consumption in building construction engineering. With the most comprehensive first-hand project data, this study is the first attempt to quantify a whole engineering project's virtual water consumption to the best of our knowledge. As numerous works have been undertaken for on-site water conservation in buildings, further efforts should be devoted to assessing water embodied in the construction process and intermediate material inputs. This research selects the construction engineering of a cluster of landmark commercial buildings in Beijing Economic-Technological Development Area as a case study and derives more than 1000 items of first-hand project data from the Bill of Quantities. Based on the standard building construction classification, the total virtual water consumption of the nine sub-projects is quantified as 1.92E+06 m3, almost 24 times as much as the on-site water consumption. As the dominant sub-project, Structure and outside decoration engineering contributes more than half of the total water consumption. Fully considering the direct and indirect water embodied in the construction engineering, building materials, in particular steel, cement, lime, and metal products, contribute to more than 3/4 the total water consumption. As the virtual water consumption of China's annual increased building areas reaches 1/4 the direct national water consumption, both direct and indirect water consumed in the process of building construction should gain full attention.
