Valves Management in the (Engineering, Procurement & Construction) industries projects:
Engineering,
procurement, construction, and management (EPCM) is a contract-based
accord between the client and the contractor. Various phases of this project
like procurement, design, construction, and overall project execution
management is comes under the responsibility of the contractor.
Engineering
During this phase,
refined P&IDs are developed and excel sheets are used to enlist the valves
named as first material take-off (MTO). MTO plus relevant valve specifications
and datasheets are sent to manufacturers to gain technical and commercial Quotation.
During bid phase,
bids are evaluated both commercially and technically and the manufacturers are
ranked accordingly. The highest bidder for each bid is finally selected for the
final meeting, and then purchase orders are signed.
Procurement
During this phase, Valves,
and Valves related document such as procedures, drawing, reports, and more are
delivered by valve supplier. Vendor documents are received and reviewed. And Valves
are finally deployed to the construction site.
Construction
During construction phase, valve engineering support and
activities
may be required as
below:
Chart 1 illustrates the lifecycle of valves from the early phase of engineering until construction in an EPC projects.
CHALLENGES
Various challenges
are faced during the different phases of EPCM:
Early Selection of
vendor
The challenge here is, during early engineering phase the amount of work associated in terms of valve qualities and quantities are not distinct and especially in case of smaller valves.
Hiring several
Manufacturers
In some cases, due
to client urgent requirement at reduced cost valves may be purchased from
vendors outside the approval list but it imposes several risk factors such as
unfamiliarity with the valve manufacturer, uncertainty about the valve
manufacturer delivery credit.
Shortage of valve
manufacturer capacity
Valve manufacturers
are usually involved in more than one order from various clients so they might
lose focus of client’s valve order. Therefore, before making any purchase order
manufacturer capacity as well as procurement, manufacturing schedule must be
verified.
Final stage valve
failure
Sometimes valves may
get damaged during the transport and later discovered at the construction site.
In some cases, valves have to returned to the manufacturer for the proper
repair which has drastic effect on the construction schedule.
