PT Wijaya Karya (Persero) Tbk (WIKA) has completed the construction\nof the Permanent Replacement Road for the Simpang Perdau\u2013Tepian Langsat\nsection in East Kutai Regency, East Kalimantan. The road, which forms\npart of the Rediversion of Muara Wahau Road Diversion (RE-MWRD) project,\nwas inaugurated as infrastructure supporting improved connectivity,\npublic mobility, and the smooth distribution of goods and services in\nthe region.<\/p>\n
The road construction is part of a long-term commitment by PT Kaltim\nPrima Coal (KPC) to the Government and the people of East Kutai to\nprovide a permanent replacement road that can be used sustainably. With\nthe presence of this 18.6 kilometre road section, inter-regional\naccessibility is expected to improve while supporting community\nactivities and economic centres in the Muara Wahau area.<\/p>\n
In this project, WIKA as the contractor built an 18.6 kilometre\nalignment with two types of pavement: rigid pavement spanning 12.85\nkilometres and Modified Cakar Ayam spanning 5.35 kilometres. The works\nalso included the construction of the Kangaroo Bridge, 40 metres in\nlength with a PCI Girder structure, as well as 24 box culverts as part\nof the road\u2019s supporting structures.<\/p>\n
One of the main challenges in building this road was the land\ncondition, which is a post-mining rehabilitation area with expansive\nsoil characteristics. These conditions required construction methods\nadapted to the soil characteristics so that the road structure would\nmaintain stability and durability.<\/p>\n
To address this challenge, WIKA applied the Modified Cakar Ayam\nsystem along 5.35 kilometres. This structure is used to help distribute\ntraffic loads more evenly and to anticipate potential differential\nsettlement on expansive soil. The application of this method is part of\nWIKA\u2019s efforts to deliver construction solutions suited to field\nconditions.<\/p>\n
During the construction process, the project involved approximately\n350 workers with a total of 1.5 million working hours achieved. The\nimplementation of occupational health and safety was an important part\nof the construction execution to ensure all works were carried out in\naccordance with established safety standards.<\/p>\n
WIKA Corporate Secretary Ngatemin said that the completion of the\nSimpang Perdau\u2013Tepian Langsat Permanent Replacement Road represents\nWIKA\u2019s contribution in delivering infrastructure that provides long-term\nbenefits for the community and supports regional growth.<\/p>\n
\u201cThe construction of the Simpang Perdau\u2013Tepian Langsat Permanent\nReplacement Road demonstrates how WIKA\u2019s competence and experience can\nbe applied to meet infrastructure needs with specific field\ncharacteristics. We hope this road will provide long-term benefits for\nthe community, facilitate mobility and the distribution of goods and\nservices, while supporting economic growth in the East Kutai region,\u201d\nsaid Ngatemin.<\/p>\n
As a permanent replacement road, this section is designed to provide\nbenefits in accordance with the service life specified in the design.\nThe presence of a road with good quality and stability is expected to\nimprove travel comfort and reliability for the public and road\nusers.<\/p>\n
More than just a transport route, the construction of the Simpang\nPerdau\u2013Tepian Langsat section carries the spirit of \u201cBuilding\nConnectivity, Driving Growth\u201d. The road is expected to strengthen\ninter-regional access, facilitate the distribution of goods and\nservices, open up opportunities for regional growth, and support the\neconomic activities of communities in East Kutai Regency.<\/p>\n
For WIKA, the completion of the RE-MWRD project is also part of the\ncontinuity of cooperation with PT Kaltim Prima Coal in supporting\nquality infrastructure development needs. WIKA is committed to\ncontinuing to deliver innovative and adaptive construction solutions\nsuited to field conditions, while providing added value for the\ncommunity and Indonesia\u2019s development.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/wika-completes-18-6-kilometre-permanent-replacement-road-for-simpang-perdau-tepian-langsat-1787230410", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
