Our company was found in 1982 under the name of ‘Navakam engineering Ltd.’ which later on May, 1986 has became Summa N.K. Contracting Co. Ltd. with paid-up capital of 25 million Thai Baht.
Since then, our company’s expertises have developed towards an international standard, which can be proved by our consistently qualified performance. Among all of our clients, we’ve become well known as ‘committed builder’ as we provide the most cost effective and high quality services, in order to achieve our clients’ highest satisfaction.
