About Us

Humbly incorporated on 16 January 1995, Irama Duta Sdn Bhd (“IDSB”) aspires to build up the nation’s infrastructures and to become a leader in the construction industry. With the main focus on its forte in delivering various civil infrastructure and building construction, IDSB strived to construct a highway that caters for the citizens from the Klang Valley regions. In 1997, the company was rewarded for its persistence and hard works as it entered into a joint venture with a prestigious local construction company to become the Build-Operate-Transfer (BOT) contractor for the Lebuhraya Damansara-Puchong (LDP) project.

The LDP project proves to be a significant milestone to the company as it subsequently propels to participate in massive national projects. Utilising its experience in infrastructure and civil engineering, IDSB constructed a 160km road from Sapulut to Kalabakan in 2004 to enhance the infrastructure standard in East Malaysia. Ever since then, the company has become very reputable among peers as it seeks to expand its specialisations by securing projects related to Trackworks, Stations and et cetera.

Recognition from the industry seems to bestow upon IDSB in 2008. This is proven when IDSB was awarded as the main contractor of the Electrified Double Track Project Package Salak Utara to Ipoh. Besides, it was also involved as a sub-contractor in the construction of Package Padang Rengas to Salak Utara. The award depicts the immense confidence shown to IDSB by the clients in the industry as this is one of the largest public infrastructures in the country. The client was, in the end, rewarded for their faiths as the project was duly delivered on time with no cost overrun. Participating in such a massive project also further reinforces the company’s impeccable track records as well as establishes its foothold in this booming industry.

Holding on to the company’s new version of “constant improvement” steadfastly, IDSB brings its project specialisations into the next level as it undertakes the construction of three Mass Rapid Transit – Sungai Buloh – Kajang Line (“KVMRT”) underground stations in 2012. The KVMRT project has been the topic of the towns since then and being a part of this mega project which transforms Malaysia into a world-class economic and tourism hub is truly a significant milestone for the company.
