BK International Inc. is Guyana's largest privately owned indigenous construction company, registered in 1993 as the successor to B&K Transportation & Construction Services. Three decades on, it is the flagship of a vertically integrated group.
Our own quarries feed our own concrete and asphalt plants. Those feed our own construction projects: moved by our own barges and our own aircraft. It is a single chain, owned end to end, built to deliver on time in one of the world's fastest-growing economies.
