Sosrobahu method is useful to overcome the process of toll road development on crowded streets ..."Jakarta (ANTARA News) - The construction of Jakarta-Cikampek II toll overlays uses Sosrobahu system, which is a construction technique, created by an Indonesian engineer named Tjokorda Raka Sukawatim, in the form of pierhead to avoid disruption of traffic flow underneath.
"Sosrobahu method is useful to overcome the process of toll road development on crowded streets, as well as underground limitations and high costs of land acquisition," PT Waskita Karya Operational Director N. Wirya Adnyana stated at the premiere of pierhead rotating in Tambun, West Java, on Wednesday.
He explained that Sosrobahu technology was a construction technique that is used primarily to twist the shoulders of the flyover?s concrete arms.
With this technique, the flyover arms are placed parallel to the road below, and it can be rotated 90 degrees so that the construction does not disturb the traffic.
The technology was once used in bypass development projects in 1988-1990 in Jakarta as well as in several other countries.
In the Jakarta-Cikampek II Elevated Toll Road project, more than 200 pierheads will be planted in the middle of the toll road, and most of them are done by Sosrobahu method.
The project is a form of joint operation between PT Waskita Karya (Persero) Tbk and PT Acset Indonusa Tbk, which signed a contract with PT Jasamarga Jalanlayang Cikampek (JJC), as a subsidiary of PT Jasa Marga (Persero) Tbk (the Toll Management Company).
The Jakarta-Cikampek II Elevated Toll Road Project is acquired by Waskita Karya with Acset Indonusa in 2017, with a contract value of Rp13.53 trillion (about US$995.8 million) and is expected to operate by 2019.
Waskita Karya has a working portion of 51 percent, with a length of about 19.7 kilometers. Until now, the work progress has reached 15.6 percent, consisting of design, pile construction work, and road widening.
Earlier, the Head of Toll Road Regulatory Agency (BJPT), Herry Trisaputra Zuna, remarked that the toll road of 1,852 kilometers will be realized in the country by the end of 2019.
According to him, the length of toll roads that the government has built until the end of November 2017 is 332 kilometers, or an increase of 156 kilometers compared to that in 2016.
Overall, toll road sections already operating in various regions across the country are 1,089 kilometers long.
