Rectification of defects, in construction, refers to the process of fixing any identified flaws or imperfections in a completed project by returning to the site and making necessary repairs or adjustments, typically done within a specified period called the "defects liability period" (DLP) where the contractor is responsible for rectifying any defects that appear during that time, following a notification from the client or project owner; this usually involves issuing a detailed list of defects, and the contractor then has to address them to meet the contractual standards.

"Compensation from the workshop" refers to the payment or financial benefit received by someone for participating in or leading a workshop, which could include a flat fee, hourly rate, per diem, travel reimbursement, or even potential future business opportunities depending on the context and arrangement.
