CSSA specializes in designing and constructing bridges and overpasses that improve mobility, reduce congestion, and connect communities. With a commitment to precision, safety, and sustainability, our large-scale structures support economic growth while ensuring reliability for generations to come.
Our strength lies in our people. With 120 dedicated staff — including certified engineers, project managers, surveyors, operators, and safety officers — CSSA combines technical know-how with hands-on experience across every stage of infrastructure delivery.
Ongoing SKA certification programs, in-house workshops, and on-the-job training ensure our teams meet the highest professional standards.
A safety-first culture reinforced by daily toolbox meetings, compliance checks, and regular drills, protecting both our workforce and stakeholders.
Deep knowledge of the regulatory landscape and site conditions in Greater Jakarta, West Java, and Central Java allows our teams to anticipate challenges and deliver with confidence.
We invest in our workforce, cultivating a team that is skilled, adaptable, and committed to delivering excellence, with senior staff actively mentoring the next generation of builders.
Our long-term collaborations with leading private developers — including Lippo, Agung Sedayu, and Jababeka — demonstrate the trust we’ve earned through consistent, high-quality delivery. These repeat partnerships are built on clear communication, technical precision, and a commitment to shared success.
For our clients, this means more than completed infrastructure: it means predictability, minimized risk, and a partner who understands their long-term vision. Whether building residential clusters, industrial boulevards, or commercial landmarks, we deliver results that strengthen both the project and the relationship.
