Defects Liability Period
Plain-Language Definition
The contractual period after Practical Completion (typically 12-24 months) during which the contractor is obligated to return and rectify any defects that appear in the completed work at no additional cost.
Technical Context
DLP (also called Warranty Period or Maintenance Period in some contracts) protects the client against construction defects that emerge after handover. Common defects during DLP: waterproofing failures, cracking, equipment malfunctions, finishing defects. The client must notify defects promptly. A portion of the contract sum (typically 5-10%) is retained as security until DLP expires.
Why It Matters
DLP is the client's safety net after construction. If defects are not reported during DLP, the contractor may be released from obligation. Proper snagging inspections at months 1, 6, and 11 of DLP are essential. Many Bangladesh projects fail to systematically track and enforce DLP obligations.
