This study describes the procedure for implementing the Incremental Launching Method for bridge construction. Apart from that, several examples of suspension bridges whose construction process used the Incremental Launching Method are also described. The examples of bridges and the Incremental Launching Method described in this study show that the construction of a bridge can be carried out efficiently, safely, and securely.

The market was developed with a total deve-lopment area of ​​9918 m2. This market is predicted to have very good future prospects, because it is located in a very strategic location. However, it is estimated that the impact of developing Tanete Market will be to increase the traffic load on the roads around the market. The aim of this study is to analyze the impact of the development of the Tanete Market, both during construction and post-operation, on the performance of Jalan Poros Bulukumba–Sinjai, where the market is located. Primary data was obtained by surveying vehicle volume, vehicle speed, and road characteristics. Meanwhile, secondary data is in the form of vehicle growth data. Traffic performance measurements were carried out using the 2017 Indonesian Road Capacity Manual. This study shows that the development of Tanete Market does not have a significant impact on traffic performance on the road where the market is located.

Referring to the Regulations of the Government Goods/Services Procurement Policy Agency (LKPP), price fairness evaluation is only carried out for bids less than 80% of OE. This is interesting to study. The Sungai Pisang Suspension Bridge Construction Work, with an offer of 84.97% to the HPS, was used as the research sample. Data show that the tender winner resigned before the expiration of his bid guarantee period due to price increases which were influenced by global economic conditions. Based on an analysis of the main payment item (MPU), 3 items of work were found with bids of less than 80% of the OE, namely: (1) supply of steel piles, amounting to 76.81% of the OE, (2) supply of structural concrete Fc'25 MPa, of 72.34% of the OE, and (3) installation of steel frame bridges of 62.60% of the OE.

This soft soil has low bearing capacity, high compressibility, and low permeability. Soil improvement using soil replacement has been common for soft soil conditions that are not thick, and this soil improvement can increase the bearing capacity of the soil and reduce the thickness of compressible soil. This study aims to perform embankment modeling using PLAXIS 2D software version 22, by comparing 3 soil models, namely the Mohr Coulomb, Hardening Soil, and Soft Soil models. Based on the modeling results, the Advanced Soil Model has a better approach compared to the Mohr Coulomb Model, which is a simple model. The results show that the Hardening Soil Model produces a settlement value that is closest to the results of 1-dimensional Terzaghi calculations. In addition, the Hardening Soil Model is the most conservative soil model, because it provides the highest settlement value, highest excess pore water pressure, and the lowest safety factor. \u0000  \u0000Keywords: toll road; soil consistency; soft soil; soil replacement; soil model \u0000  \u0000  \u0000Abstrak \u0000  \u0000Tantangan dalam perancangan Jalan Tol Subang adalah pada kondisi tanah asli, dengan konsistensi tanah antara sangat lunak hingga lunak. Tanah lunak ini memiliki daya dukung yang rendah, kompresibilitas yang tinggi, dan permeabilitas yang rendah. Perbaikan tanah menggunakan soil replacement telah biasa dilakukan, untuk kondisi tanah lunak yang tidak tebal, dan perbaikan tanah ini dapat meningkatkan daya dukung tanah serta mengurangi tebal tanah kompresibel. Studi ini bertujuan untuk melakukan pemodelan timbunan dengan menggunakan perangkat lunak PLAXIS 2D versi 22, dengan membandingkan 3 soil model, yaitu model-model Mohr Coulomb, Hardening Soil, dan Soft Soil. Berdasarkan hasil pemodelan yang dilakukan, Advanced Soil Model merupakan pendekatan yang lebih baik dibandingkan dengan Mohr Coulomb Model, yang merupakan model sederhana. Hasil yang diperoleh menunjukkan bahwa Hardening Soil Model menghasilkan nilai penurunan yang paling mendekati hasil perhitungan 1 dimensi Terzaghi. Selain itu, Hardening Soil Model merupakan soil model yang paling konservatif, karena memberikan nilai penurunan yang terjadi dan angka air pori ekses yang paling tinggi serta nilai faktor keamanan yang paling rendah. \u0000  \u0000Kata-kata kunci: jalan tol; konsistensi tanah; tanah lunak; soil replacement; soil model","PeriodicalId":122843,"journal":{"name":"Jurnal HPJI","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132675263","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}
