INACON has provided construction supervision, project management, appraisal, and technical advisory services for national and regional transport infrastructure projects, including strategic road corridors and cross-border connectivity initiatives. Experience covers Indonesia, Timor-Leste, and the Greater Mekong Subregion (Lao PDR) under ADB, Islamic Development Bank, and government financing.

We provide project supervision consultancy (PSC), construction supervision, and technical advisory services for national and regional road corridors, including new construction, rehabilitation, and upgrading works. Our supervision services cover contract administration, quality assurance, inspection and testing, design and method review, payment certification, safeguards compliance, and health and safety oversight, ensuring technical quality, cost control, and timely delivery. We also support clients through progress reporting, variation and dispute management, and preparation of as-built drawings and handover documentation

Several assignments emphasized strategic connectivity and corridor development, such as the Trans South–South Java Road Project, which expanded paved road and bridge networks to strengthen accessibility along Java’s southern corridor, and the Greater Mekong Subregion East–West Economic Corridor Towns Development Project, which integrated urban roads with wastewater and solid waste infrastructure. In Timor-Leste, INACON supervised road construction and rehabilitation projects that addressed deteriorated road conditions, reducing travel time, vehicle operating costs, and isolation of rural communities.

Key outcomes and impact include improved road quality and safety, enhanced regional and local connectivity, reduced travel time and logistics costs, and strengthened capacity of transport agencies to manage and maintain major infrastructure assets.
