Explanation of Unusual or Complicated Terms

CIDB 1SN Grading: The Construction Industry Development Board (CIDB) grading system classifies contractors based on financial capacity, project complexity, and historical performance. The "1SN" designation specifically applies to roofing and waterproofing works. This minimum requirement ensures that only contractors with verified technical expertise, adequate financial standing, and proven experience in this specialised field can participate, thereby reducing execution risks and guaranteeing compliance with national construction standards.
