Module 6: Preventing corruption in project construction
Controls: quantity
Implement effective controls over the provided quantity of the works.
The project owner’s procurement controls (covered in a separate module) ensure that the appointed contractor is capable of providing the required quantities.
Ensure that the contract with the winning contractor states:
the required quantities
an appropriate method for measuring quantity (e.g. spatial measurement of area or volume, counting of items).
Appoint a sufficient number of qualified and honest site supervisors who are responsible for ensuring that the contract quantity is provided by the contractor and who:
compare actual quantity against required contract quantity
measure items which are to be covered over before covering
keep appropriate records of provided quantity (e.g. photographs, work records, delivery notes, supplier invoices)
cross check overlapping records for consistency: e.g: check quantity statements for a particular item in each of:
supplier quantity records (delivery note, invoice)
site quantity records (site gate records)
measurement records
are alert for any suspicious indicators in relation to quantity.
Appoint two supervisors for high value or high risk items.
