PT Grha Bintang Utama carried out the Repair of the Callendar Hamilton (CH) Bridge at Jetak under the Public-Private Partnership (PPP/KPBU) scheme as part of its commitment to maintaining the reliability and operational performance of Weigh In Motion (WIM) systems and supporting transportation infrastructure.

This repair project was undertaken to ensure that all bridge components and associated systems continue to function optimally in supporting vehicle weighing operations, freight transportation monitoring, and the enforcement of Over Dimension Over Loading (ODOL) regulations. Due to continuous operational use and exposure to environmental conditions, periodic inspection and repair activities are essential to maintain system accuracy, infrastructure integrity, and operational safety.

The scope of work included condition assessment and technical evaluation of existing infrastructure, inspection of structural and supporting components, implementation of corrective repairs, and comprehensive testing to ensure the system met operational and performance standards. All activities were conducted in accordance with safety regulations, engineering best practices, and quality assurance requirements.

As a critical element of Indonesia’s transportation infrastructure network, the Callendar Hamilton Bridge plays an important role in supporting the monitoring of heavy vehicles and protecting roads and bridges from excessive loading. Through this repair project, PT Grha Bintang Utama contributed to maintaining the reliability of infrastructure assets and ensuring the continuous availability of accurate operational data for transportation authorities and infrastructure operators.

The successful completion of the CH Jetak PPP repair project demonstrates PT Grha Bintang Utama’s expertise in transportation infrastructure maintenance, rehabilitation services, and intelligent transportation technologies. This project further strengthens the company’s portfolio in Weigh In Motion (WIM) systems, ODOL monitoring, smart transportation solutions, and infrastructure asset management throughout Indonesia.
