Sanjo City Comprehensive Private Sector Outsourcing Project

Sanjo City, which has been actively promoting comprehensive private sector outsourcing for infrastructure maintenance and management, began Phase III (5-year) of outsourcing in the spring of 2024. PACIFIC CONSULTANTS has been participating as a member of the joint venture (JV) that will receive comprehensive outsourcing since Phase II (April 2019 - March 2024), which precedes this. This is the first time for a construction consultant in the country to do so. Why did they join a JV that is mainly made up of local construction companies, and what kind of results have they produced? Inami Nobutaka, General Manager of the Spatial Creation Office of Infrastructure Management Dept. Transportation Infrastructure Div. who is at the center of the initiative, along with Nakai Ryo and Matsuoka Masahiro from the same office, explain the situation.

What is Comprehensive Entrustment of Infrastructure to Private Sector?

How to protect infrastructure such as roads with limited personnel and budgets is a major issue for local governments. One promising method that is garnering attention is "Comprehensive Entrustment to Private Sector." We spoke with three people from PACIFIC CONSULTANTS who have pioneered this field and have achieved many successes: Nobutaka INAMITSU of the Spatial Creation Section, Infrastructure Management Dept., Transportation Infrastructure Div.; Kazuya MURAMATSU of the Infrastructure PPP Section, PPP Management Dept., Social Innovation Div.; and Shigeto TANAKA of the Infrastructure Management Section, Transportation Infrastructure Dept., Osaka Headquarters.

Hokuriku Shinkansen Tsuruga Extension Project Vol.1 ~ Okura Yoza Bridge ~

The Shinkansen, which travels at a speed of 260km per hour, requires extremely high precision in its bridge piers. The allowable deflection is only a few millimeters. This is why engineers who aspire to be civil engineers think, "I want to work on the Shinkansen someday." Furthermore, the Okura Yoza Bridge had to be built on soft ground with a maximum pier's height of about 30m. This was one of the most difficult projects in the long history of Shinkansen construction.
