Facilitators and Barriers in Applying Building Information Modeling (BIM) for Construction Industry

The authors provide a holistic perspective to enhance BIM working environment for more efficient smart construction settlements. An in-depth survey with 40 questionnaires was distributed to 100 professionals in construction, design, engineering, government. Although 45% of the respondents have received a certain form of BIM education, more than 94% of the respondents have answered that there should be a formal BIM education. Both design and construction experts have reported that the biggest advantage of using BIM is in its error checking ability. It can reduce design errors and increase construction ability. More than 79% of the respondents agreed upon a proper compensation for BIM implementation. The majority of opinions have revealed that there should be an increase in construction and design fees. There are a number issues for a successful BIM application: (1) guidelines and details for BIM work and delivery; (2) more standardized BIM education; and (3) a proper compensation system for BIM work. The results show that BIM professionals are ready to adopt the consequences of using BIM, but administrative and institutional preparations are not available beforehand. There should be a higher level of regulatory concern and provision of administrative solutions for successful BIM applications.

Driving Forces for the Spatial Reconstruction of Rural Settlements in Mountainous Areas Based on Structural Equation Models: A Case Study in Western China

Rural settlement development in mountainous areas is the key to eliminating global hunger and poverty. The spatial reconstruction of rural settlements in mountainous areas can promote rural development in mountainous areas. In this study, the Panxi area—a typical mountainous area in China—was chosen as the study area. The driving forces for the spatial reconstruction of rural settlements in mountainous areas were explored from the perspective of peasant households by combining participatory rural appraisal (PRA) with structural equation modeling (SEM). Results showed that: (1) 62.03% of the 266 peasant households included were willing to have spatial reconstruction, indicating that most peasant households in mountainous areas have a very strong intention towards the spatial reconstruction of rural settlements. (2) Infrastructure, medical conditions, living environment, farming culture, and dietary habits significantly influenced the reconstruction intention of peasant households. In contrast, development opportunities, place attachment, language, and living mode each had a slight influence. (3) Geological disasters were the main driving force for the spatial reconstruction of rural settlements in mountainous areas, whilst the driving force of living cohesion was the smallest. This study provides insights for future planning and construction of rural settlements in the Panxi area and spatial reconstruction practices. It has important practical significance for overcoming poverty and realizing rural revitalization in mountainous areas.

İŞĞALDAN AZAD OLUNAN RAYONLARIMIZIN COĞRAFİYASI VƏ BU RAYONLARA BÖYÜK QAYIDIŞ

2020 was a difficult period for all countries of the world. Pandemic world the economic crisis has had a serious impact on the economies of most countries. The state and people of Azerbaijan, in spite of all the economic and social damage and the material damage caused by the war, shielded the aggression against them and launched a counter-operation to liberate the lands. If we pay attention to the main parameters of the economic potential of the occupied territories, we can see that Karabakh and its environs Lachin, Kalbajar, Gubadli, Zangilan, Jabrayil, Aghdam, Fuzuli were occupied by Armenia in 1989 and 1993, and the infrastructure of the regions was destroyed. For this reason, future restoration work began with the construction of general infrastructure and primary settlements, and at a later stage should be transferred to economic development projects. Our liberated territories cover two economic geographycal regions. Kalbajar-Lachin and Upper Karabakh. During the occupation of our lands, all buildings were destroyed, forests, reserves, monuments, parks, museums were destroyed. In addition, industrial and agricultural areas, power lines, mineral deposits, transport hubs were severely damaged. After a historic victory in 2020, which resulted in the liberation of the occupied territories of our country, Azerbaijan enters a new stage. The geography of reviving Karabakh must be studied by every citizen. There is a need to restore the landscape of this areas, mineral deposits, industry, electrical systems, roads, tourists sites Key words: Nagorno Karabakh, Natural landscape, tourism, economy, mineral waters, industry, minerals, electric power, priority, great return

Characteristics of Ground Surface Settlement of Double-Line Adjacent Metro Construction in Sandy Cobble Stratum: A Case Study of Beijing Airport Line

As a long-term urban transportation infrastructure, the stability of metro construction is very important. With the continuous expansion of urban metro network, metro adjacent construction is more and more frequently encountered. In this paper, taking the double-line adjacent construction problems encountered during excavation of Beijing New Airport Line metro in sandy cobble stratum as an example, the surface settlement caused by excavation of single-line metro and double-line adjacent metro is studied by computed tomography scan, electron microscope scanning, laboratory mechanical tests, orthogonal inversion and numerical simulation and other methods. The results show that 1) the sandy cobble particle size and sandy cobble distribution of Beijing sandy cobble samples are relatively dispersed, and the sandy cobble particle size is from 3 to 20 cm, of which the largest proportion is the sandy cobble particle size from 5 to 8 cm. 2) The internal friction angle of Beijing sandy cobble samples with different moisture content is from 27° to 40°, which is much larger than that of other soil samples. Even at the post-peak stage, the shear stress of some sandy cobble samples does not gradually tend to be gentle, but continuously increases or has secondary peaks. 3) For the excavation of double-line adjacent metro, the maximum settlement difference and the impact range of excavation are proposed as indicators to investigate the degree of interaction of the adjacent metro. 4) The results of numerical orthogonal analysis show that the width of surface settlement zone increases significantly with the increase of tunnel diameter and spacing when excavating adjacent metro in sandy cobble stratum, but the rate of increase with tunnel diameter (from 6 m to 14 m) almost reaches 2 times of the rate of increase with the spacing (from 3 m to 15 m). 5) The maximum settlement value of sandy cobble stratum increases with the increase of tunnel diameter and decreases with the increase of spacing. The orthogonal linear analysis shows that the influence of tunnel diameter on the maximum settlement value is much greater than the spacing. The maximum settlement increases with the increase of tunnel diameter, which is about 3.6 times of that with the decrease of spacing.

Abstract. Chrysanthemum × hortorum Bailey is a perennial plant of the Compositae family. Perhaps the most famous and demanded late-flowering culture, which is used both for landscaping the private sector and in the green construction of settlements. However, its use in the soil and climatic conditions of the Bashkir Ural is difficult due to the lack of varieties adapted to local conditions and a reasonable assortment. The aim of the study was a comprehensive assessment of varieties of chrysanthemum from the collection of the South-Ural Botanical Garden of Ufa, taking into account the directions of use. Methods. In accordance with the methodology of E. S. Pidgainaya and other authors plants went through two stages of analysis: at the first stage, the most decorative and stable varieties were identified; on the second, the perspective direction of use of each of them was determined. At the first stage, decorative (decorativeness of a bush, leaves, inflorescences; aroma; variety uniformity; abundance of flowering) and economically valuable (productivity and flowering duration; drought resistance; winter hardiness; resistance to adverse conditions, diseases and pests; intensity of vegetative reproduction) signs were assessed. Results. As a result of the analysis of the decorative qualities of 112 varieties of chrysanthemum, ten were identified (Aktanysh, Anyuta, Belosnezhka, Vecherniye Ogni, Opal, Pektoral, Rozovaya Mechta, Solnechnaya Feyeriya, Solnyshko, Ufimskaya Yubileynaya), which have a high decorative effect of the bush, a weak aroma and are characterized by abundant flowering; they are rated 49–50 points. 84 varieties are rated 40–48 points, they have less abundant flowering and a stronger aroma. According to economically valuable traits, the highest number of points (48–49) was awarded to 4 varieties (Aktanysh, Nezhnaya Muza, Akiwa Yellow, Kurochka Ryaba). The lowest total score (34) belongs to the variety Golden Dukat. As a result of the comprehensive assessment, 106 varieties were classified as highly promising, they scored more than 80 points; six varieties are promising, they are estimated at 60–80 points. Scientific novelty. At the second stage of the analysis, when determining a promising direction of use, it was revealed that most varieties (88) can be recommended for garden use and 25 for container crops.

Peremajaan “Brandgang” Sebagai Akses Penunjang Sirkulasi Antar Gang Di Lingkungan Perumahan Babatan Pilang

In the changing times from year to year the development process is always progressing. No exception to the construction of settlements and housing scattered in the city of Surabaya. Arrangement of a housing environment is an important factor in improving the quality of life of residents in society. The residential space pattern in Babatan Pilang still maintains the brandgang system. The function of this brandgang itself is as a fire breaker to slow down or stop fires. Apart from the two main functions, brandgang indirectly also acts as a connection path between alleys or roads. The existing condition of the brandgang in the Babatan Pilang housing complex is not neat and well maintained. In general, the brandgang should not present a tense and frightening atmosphere. The method used is extracting data again looking at the aspects of the problems that exist in relation to the existence of brandgang so far. The function and role of brandgang wherever good and their existence are not necessarily forgotten and are more important, this is because brandgang is one of the main factors of a security system in a settlement or housing. Presenting a neat and orderly brandgang will create a good impression in restoring its main function. &#x0D;

Riesgos socioambientales derivados de la pérdida de servicios ecosistémicos: el caso de Ecatepec de Morelos, Estado de México

This paper was originated in an investigation carried out in the Municipality of Ecatepec de Morelos in the period from October 2019 to March 2020, and which served as support for the update of the Municipal Urban Development Plan 2020 for the same municipality. The purpose is to recognize the socio-environmental factors that drive the construction of human settlements in ecological conservation areas and that, in the medium term, alter the surrounding ecosystems and increase their vulnerability to geological and hydrometeorological phenomena. Through an environmental risk analysis methodology, the socio-environmental impacts generated by irregular settlements on ecological conservation areas are analyzed, as the houses are located in areas of high slope, it makes them more vulnerable to the phenomena mencioned. Even these areas are accessible to certain sectors of the population, in terms of rent or purchase of housing, such practices are usually illegal, and bring with them the deterioration of the existing natural vegetation, in addition to the loss of ecosystem services derived from the unplanned urban growth. These invasions correspond to a permanent process that includes complex variables, such as the deterioration of the quality of life, economic insufficiency to satisfy needs and in a synergistic way, generates social problems such as insecurity and violence.

Study on Surface Settlement Law of Shield Construction in Mudstone Stratum

In order to explore the influence of groundwater on the surface settlement law of shield construction under mudstone with different weathering degrees, this paper studies the influence of buried depth on surface settlement under different weathered mudstone, and the influence law of groundwater in stratum and different depths of water level on settlement of shield construction using a three-dimensional(3D) numerical model establish by finite element software based on the engineering background of Chengdu Metro Line 18. The results show that: (1) With the increase of buried depth, the range of lateral settlement trough on the surface gradually increases, but the maximum settlement gradually decreases. By analyzing the buried depth and the maximum surface settlement, it is found that the buried depth ratio has a logarithmic relationship with the corresponding maximum surface settlement. (2) The construction settlement increases obviously when there is groundwater in the stratum compared with when there is no groundwater. (3) The depth of water level above the vault and the maximum settlement caused by shield construction basically conform to the linear law. For every 1m increase in the depth of water level above the vault, the maximum settlement value can increase by about 0.43 mm. Compared with the field monitoring data, the calculation results are basically consistent, which shows the reliability of the calculation. This paper aims to provide experience for similar projects.

Consolidation of soft clay foundation improved by geosynthetic-reinforced granular columns: Numerical evaluation

Soft clays are problematic soils as they present high compressibility and low shear strength. There are several methods for improving in situ conditions of soft clays. Based on the geotechnical problem's geometry and characteristics, the in situ conditions may require reinforcement to restrain instability and construction settlements. Granular columns reinforced by geosynthetic material are widely used to reduce settlements of embankments on soft clays. They also accelerate the consolidation rate by reducing the drainage path's length and increasing the foundation soil's bearing capacity. In this study, the performance of encased and layered granular columns in soft clay is investigated and discussed. The numerical results show the significance of geosynthetic stiffness and the column length on the embankment settlements. Furthermore, the results show that granular columns may play an important role in dissipating the excess pore water pressures and accelerating the consolidation settlements of embankments on soft clays.

Flow-line production method in the residential construction: analysis of the state, problems and development trends

Methods in the modern residential construction must meet the requirements for the effective use of material and labor resources. Today, three methods are used in construction: successive, parallel, and flow-line methods. The most progressive and providing a rhythmic output of construction products and an even use of resources is the flow-line method. The article considers the use of the flow-line method of the residential construction both in high-rise multistorey construction and in low-rise construction of suburban settlements (micro-districts). In the work, we analyze the problems and prospects of using the flow-line method of construction in the Irkutsk Region. We discuss main advantages and disadvantages of the most common technological and constructive solutions of the flow-line method in the residential construction. The paper analyzes possible combinations of methods in the residential construction. It has been found that when using the parallel-flow method, the duration of construction is reduced by an average of 20%, and labor productivity increases by about 10%. The economic efficiency of the flow-line (parallel-flow) method is manifested in the reduction of construction time, reduction of downtime of resources and (or) individual spreads of work, increasing labor productivity and the profitability of the residential construction.

Study on Surface Settlement of Water-Rich Sand Pebble Bed Shield Construction in Nanchang

Water-rich sand layer is a kind of common bad geology that is difficult to control and has great harm. It is easy to cause serious problems such as collapse, water inrush and sand burst, and surface collapse, etc. Through the analysis of shield tunnel of water-rich sand layer in Nanchang city, a numerical model was established to study the influence of different working conditions on surface settlement. The results show that the influence of boundary conditions should be considered more than other soil layers, the influence of different grouting pressures on the surface settlement of the sand and gravel soil layer is not obvious, the surface settlement caused by the water level reduction is greater than that caused by the water level reduction, and increasing the grouting pressure has a certain control effect on the ground settlement after precipitation.

Influence of Shield Tail Clearance on Surface Settlement during Shield Construction in Soft Soil Area

The shield construction process of shield tail gap caused by formation damage, the formation damage caused by the settlement is as long as the part of tunnel subsidence analysis, therefore in the finite element software analysis of shield construction settlement value, the shield tail clearance simulation is an important link in the entire model, this article analyzes three common finite element simulation method, shield tail clearance displacement convergence method based on non-uniform distribution and actual matches are higher than layer such as generation method and stiffness discount subtraction. Finally, the displacement convergence method is used to simulate the grouting effect of shield tail on the surface settlement.

Seismic zoning of Tabriz area by stochastic finite fault model considering site-specific soil effects

Abstract Tabriz, as one of the most earthquake-prone cities in the Iran plateau, has experienced enormous earthquakes that have even destroyed the city altogether. Considering this seismological background and the vicinity of Tabriz's northwestern fault, reducing the possible earthquake losses can be highly useful by scrutinizing the strong ground motion resulting from the fault activation. To this end, a stochastic finite-fault ground motion simulation (EXSIM) method was applied as an important means for predicting the ground motion near the epicenter of the earthquake. EXSIM is an open-source stochastic finite-fault simulation algorithm that generates the time-series of the earthquake's ground motion. Based on the findings, the peak horizontal acceleration reached 0.83 g in the northern parts by creating artificial accelerograms and Tabriz's seismic zonation. In comparison, it reduced by 0.48 g by departing from the fault in the city's southern parts. Additionally, providing a seismic zonation map in Tabriz revealed that stopping the construction in the north parts while extending the settlement construction to the south part of the city are considered vital and unavoidable. Also, by applying the magnification and effects of the soil layers above the bedrock, it was further found that the existence of the loose layer with low strength and compaction intensify the application of seismic acceleration on the near-surface structures in the central, west, and southwest parts of the target area.
