According to statistics from nearly 100 projects which Phan Vũ has constructed by preboring method in Vietnam, the percentage of projects can control the budget is up to 100%. In particular, more than 5% of the projects save budget compared to the original plan.
Hyper-MEGA method on sand area - The Arena Cam Ranh project
Pre-boring method has a very high level of accuracy in the time frame for doing the work, so it consumes less time for troubleshooting, including design adjusment. The average speed of a set of drilling equipment can be constructed from 150 - 200m pile / day, twice as fast as bored pile construction if calculated on one unit loading pile implementation.
Pre-boring method according to Japanese standards with many measures, including Basic method and Hyper-MEGA method (two most popular technologies of pre-boring method in Vietnam) that has been granted exclusive protection by Japan Pile Corporation all over the world and Phan Vu is only company to transfer this technology in Vietnam from 2010.
