Procurement Management
Procurement management may be defined as the combined functions
of purchasing planning, vendors qualification, purchasing, inventory
control, traffic control, quality control, and salvage operations.
Procurement management is a concept originally introduce by
governments whereby the purchasing function is expanded from
merely exchanging money for goods to one of total responsibility
for acquiring goods.
From the project management point of view, procurement functions
vary according to the job progress within the project life cycle.
Since material supply for projects is usually one of the main
components of the total construction effort, special attention should
be given to the functional organization that will be handling the
procurement operation.
Procurement during conceptual estimate paper and design basis paper,
is limited to consulting services from the engineering department
about:
- Vendoravailability;
- Marketconditions;
- Orderofmagnitudeestimates;and
- Deliverytimeestimates.
This consulting service is a simple but vital function considering that
project procurement cost is usually found to be 40 to 60 percent of
the total cost of the project.
During Project Proposal (PP) development the main function of the
procurement organization should be the creation of an acquisition
schedule for long lead time materials according to the project
milestone schedule implemented within the project execution plan.
The acquisition schedule is usually called the Long Lead Time Material
(LLTM) and equipment schedule and it is always a commanding
element for the total project duration.
Additionally, during the project proposal phase preliminary materials
take-off (TO) is carried out and a program for procurement of items
other than LLTM is established. Materials 'take-off' (TO) is an
engineering function that consist of reading design
drawings and producing material and equipment schedules required
for supporting construction of the project.
Once the material/equipment TO's are completed, purchase
requisitions are generated.
