In 1981, with the dawn of the open economy, six enterprising individuals teamed up to form what was to become one of Sri Lanka's Best-known enterprises. Sierra Construction Limited was incorporated to venture into the fields of Civil and Telecommunication Engineering, sectors that were hitherto solely dominated by foreign companies or by companies with foreign collaborations. Within two decades, Sierra rose to become the market leader in Telecommunication Engineering. The boom in the construction industry opened up many opportunities for Sierra and the company has today evolved to great heights handling large construction projects relating to Water Supply & Sewerage, Power, Roads, Buildings, Irrigation and Pilling besides Civil & Telecommunication.
