Progress Payment Certificate Ndi Mini?

Progress payment certificate ndi document ya semmuso i bveledzwaho nga principal agent (architect, engineer kana quantity surveyor) ine ya khwaṱhisedza mutengo wa mushumo wo no fhela nga contractor na u tendela badelo nga employer. Iyo certificate i shuma sa valuation document na payment instruction.

Zwiṱalusi zwa ndeme:

Valuation document — I sumbedza mutengo wa mushumo wo no fhela u swika zwino
Payment instruction — I tendela badelo ya amount yo certify-iwaho
Legally binding — I vhea mushumo kha employer uri a badela
Regular intervals — I bveledzwa ṅwedzi muṅwe na muṅwe kana nga tshifhinga tsho buiwaho kha contract
Net amount — I sumbedza amount yo teaho nga murahu ha deductions

Payment certificates ndi yone nḓila ine contractor a wana tefo ya misi yoṱhe nga yone musi project i tshi khou bvela phanḓa, hu si u lindela u fhela ha project. Dzi bveledzwa fhasi ha contract forms dza ndeme Afurika Tshipembe: JBCC (Joint Building Contracts Committee), NEC (New Engineering Contract), na GCC (General Conditions of Contract).
