(Construction) - For many years, the National University of Civil Engineering (NUCE) and JFE Steel Corporation, Japan have implemented many research cooperation programs to deploy Japanese advanced technology applications to suit with construction of Vietnam.

One of the joint research activities to implement advanced technology application is the Basic Standard (TCCS) of rotary penetration steel pipe pile with a toe wing - Tsubasa pile of Vietnam- Japan Institute for Advanced Technology (VJIAT), NUCE is a typical actitivity. This standard specifies the basics of Tsubasa pile construction process from the planning, construction methods and management (closed-end type and open-end type).

| Closed-end type and open-type type. |
This Tsubasa pile type has been recognized by the Japan Construction Technology Review and Certification to meet high technical standards, therefore the products of rotary penetration steel pipe pile with a toe wing are widely applied to works in urban areas in Japan. This method of construction of piles causes low noise, low vibration and is applicable to narrow, limited and environment-friendly spaces because it does not create waste soil or groundwater pollution. JFE Steel Corporation has been promoting the application of this advanced method to develop infrastructure in Southeast Asia based on the company's technical certification in each country.

| Acceptance of Standards at NUCE. |
Vietnam- Japan Institute for Advanced Technology, NUCE and JFE Steel Corporation carried out this study from August 2016 and completed in January 2018. The initial results were presented by experts from both sides at a training session on standards of the Ministry of Construction in Hanoi in August 2019 and Da Nang in September 2019.

In the future, it is expected that this standard will be officially recognized and its application will be developed for infrastructure works in Vietnam to avoid current weaknesses of other methods.
