Using primary and secondary data obtained from a survey, this study explores the service coverage area for three facilities (housing facilities, government and educational infrastructures) along the Corridors 2 and 3 using network analysis in Quantum GIS (QGIS). Two variables, pedestrian distance (400 meters) and cyclist distance (2000 meters), were applied in this study. The results showed that Corridor 2 served 86 infrastructures for the pedestrian distance variable and 367 infrastructures for the cyclist distance variable, while Corridor 3 served 89 infrastructures for the pedestrian distance variable and 217 infrastructures for the cyclist distance variable. The study found that the total service coverage area along Corridors 2 and 3 is wider for cyclists than for pedestrians. Moreover, this study highlights the presence of urban sprawl in the regions served by both Corridors.","PeriodicalId":30107,"journal":{"name":"Civil Engineering Dimension","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46387033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its development in construction industry is lagging compared to other industry, especially in Indonesia. This research empirically evaluates the impact of contractors’ safety leadership on construction workers’ safety behavior. It explores three dimensions of safety leadership variable and two dimensions of safety behavior variable, and then examines the relationship between the two variables. Data was gathered through questionnaire survey to eighty-four workers from five on-going construction projects in Surabaya. Multiple regression analysis was performed to examine two models of the impact of safety leadership on safety behavior. The findings suggest that safety concern and safety motivation positively impact safety compliance and safety participation, whilst safety policy only have a significant positive impact on safety participation. The paper discusses these findings and their implications for shaping workers’ safety behavior in construction projects.","PeriodicalId":30107,"journal":{"name":"Civil Engineering Dimension","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42355827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The LVL Sengon wood material used Hill failure criterion with isotropic hardening rules, and its mechanical properties in both tension and compression are modelled according to its mechanical properties in tension obtained from the clear specimen test. The contact analysis is defined for each contacting and contacted elements. The FEA results well agreed with the experimental results in term of the load-deflection curve and failure mode of the beam.

Due to its remote location, mitigations to strengthen the soft clay are deemed too costly and/or require significant time to mobilize. Without mitigations, the presence of this very soft clay necessitates the roadway embankment to be constructed in phases to allow partial consolidation of clayey soils to take place before additional embankment fill can be placed. At each construction phase, the additional fill thickness and staging time are determined, and the corresponding degrees of consolidation and incremental strength gains are calculated at discrete grid points within the soft organic clay. The stability of the partially built embankment is then evaluated, and the fill thickness and staging time are adjusted to meet the stability safety requirements. The settlement due to fill placement can be estimated at each construction phase and included as an overbuilt to the next fill placement thickness. Impacts of soil horizontal and vertical movements due to filling to pile foundations are also be discussed.","PeriodicalId":30107,"journal":{"name":"Civil Engineering Dimension","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48866155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to identify the elasticity value of travel time and travel cost of the users of private vehicles and public transportation. Using data from users of private vehicles and public transport in Bandung, Indonesia, the elasticity of travel time and travel cost was calculated based on estimated multinomial logit model (MNL) logit. The elasticity was calculated based on gasoline prices, parking fees, transfer fees, access times, travel times, and waiting times. Based on the results of the elasticity values for travel attribute, it was found that in access time and travel time, Trans Metro Bandung (TMB) Bus had the largest elasticity of -0,564 and -5,001, respectively, so TMB Bus was the most sensitive to changes in access time and travel time. In terms of waiting times and fixed costs/gasoline, conventional taxi has the highest elasticity values of -2,630 and -1,604, respectively, so conventional taxi is the most sensitive to changes in waiting time and fixed costs/gasoline.","PeriodicalId":30107,"journal":{"name":"Civil Engineering Dimension","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44020353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laterite samples were stabilized with 1M and 2M PA at 5, 10 and 15%, respectively, by weight of dry soil. Some PA stabilized laterite were further mixed with an alkaline activator. All the stabilized laterites were moist cured for up to 14 days. The results show that the laterite was unsuitable as a road construction material in its natural state. The CBR of PA stabilized laterite improved with about 25%, while that with alkaline activation showed more improvement of up to 145%. The UCS of PA stabilized soil and that with alkaline activation increased with about 250% improvement.

The low to medium cohesionless soil consistency is predominantly observed on the upper subsoil. A shallow groundwater level and low fines content have also enlarged the likelihood of earthquake-induced liquefaction. An SPT based liquefaction triggering procedure is adopted in this study to indicate the Factor of Safety (FoS) whereas the Liquefaction Severity Index (LSI) is used to measure the severity of liquefaction by presuming its manifestation. Inverse Distance Weighted (IDW) interpolation in QGIS is chosen to produce a map with 50 m × 50 m grid size. The analysis results show the YIA’s area is prone to undergo liquefaction at various depths. However, thin liquefied layers may not generate sufficient artesian flow pressure to eject water or sand.
