About Sierra

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.
