Abstract
It is no doubt that Isambard Kingdom Brunei made a significant contribution to the world and established himself as a leader in his selected field. In this report, his engineering spirit that designed and conducted his great work, for example railway, ships, tunnels, cuts and stations, has been discussed through practical illustration. Presumably, the training given to 1KB by his father Mark Brunei led to his engineering spirit and its core is creative imagination based on mathematical skill, love and passion, patience, challenging and dreaming.
