Control Valve Technical Bid Evaluation


Technical bid evaluation  is an important part of an EPC project and both cost and schedule have large impacts.

Control valve and other critical items have more importance of this activity. After doing three major EPC projects with client like GASCO and ADCO I have got good experience and I would like to highlight the important parts of this activity.

Data Sheet

While developing technical data sheet it is important that special attention be given to :

What material is specified for the body, stem, plug, ball and other wetted and non wetted parts of the valve.

The selection of proper material is important since it has large cost impact special if the process is corrosive and custom material are required for wetted parts

Leakage class of the valve

The leakage class should be clearly mention. The classes range from class IV to VI. The later being more stagnant.

Stroke timings

The stroke timings are necessary to be specified since vendor shall select actuator accordingly

Fail Safe Condition

Once the fail safe condition is specified, the valve is designed accordingly. It can be either fail open  or fail close.

Test Requirements

All the required test must be clearly mentioned on the data sheet like material test certificate, leakage test, NDE test and other project specific test required

Material Requisition

Material requisition is also important pre-bid evaluation document. All the  codes and standards to be complied should be listed like ASME, IEC, ISA and other applicable codes.

The documents required from vendor should be listed and also the inspection and test plan should be tabulated.

Once these pre-bid documents are prepared and quotations are received then the quotes are evaluated for technical compliance.

The technical bid evaluation should be prepared in such a way that point by point compliance is obtained from vendor but it should be easy to understand by all three parties(client, contractor and vendors). The best way I have practiced and which is followed in good engineering practice in an EPC project is to tabulate the requirements of both material requisition(clause wise) and the requirements of the data sheet(items wise) and then obtain vendor compliance confirmation in adjacent column of the same table.

It is also important that the confirmation items should also be  reflected in vendor’s technical offer

This practice helps optimizing the time required for technical clarification with vendors and the same document can and should be used for multiple vendor of the same item,

All the deviations of the vendor should be clearly marked and highlighted and be shared with client for approval.

Life as We Live it


I was trying to write some thing. I typed then deleted  some lines and at the end what matters is how we live the life.

Our thought pave the path which mold our lives. There is nothing as destiny, all that unfolds is what we attempt for and the one we don’t try always remains never seen and whatever we can think is possible to be turned into reality.

Life is a beautiful bitch, at first it attracts you but once you catch it  suck as everything back in past but yet again it gives the satisfaction of being achieved than sitting and doing nothing.


			

House MD


So yet again I felt I did late in watching House MD. It is one of the best series I have come across and enjoyed watching. This story is about an anti social mavric doctor who has his unique way of diagnosing unsolved illnesses. It has every thing. The curiosity and craziness of Dr House, the commitment of Dr Cuddy, the gentleness of Dr Willson. The story is both entertaining and useful specially for the medical field. The unique part of the whole series is the misery of Dr house whole life and his unique way of dealing both the patients and his team.

The character of Dr House is  the epic part of the series and the friendship of the trio(House, Cuddy and Willson) is most awesome part throughout the series. The teaching method of Dr House to his teammates and young doctors is perhaps the craziest and unique way.

Some of the most memorable moments and quotes of the series are :

Everybody Lies.  Dr House

People never change, the become more of who they really are. Dr House

If you are dieing, suddenly everyone loves you. Dr House

The Circle of Joy!


And old story tells that one day, a countryman knocked hard on a monastery door. When the monk tending the gates opened up, he was given a magnificent bunch of grapes.

– Brother, these are the finest my vineyard has produced. I’ve come to bear them as a gift.

– Thank you! I will take them to the Abbot immediately, he’ll be delighted with this offering.

– No! I brought them for you. For whenever I knock on the door, it is you opens it. When I needed help because the crop was destroyed by drought, you gave me a piece of bread and a cup of wine every day.

The monk held the grapes and spent the entire morning admiring it. And decided to deliver the gift to the Abbot, who had always encouraged him with words of wisdom.

The Abbot was very pleased with the grapes, but he recalled that there was a sick brother in the monastery, and thought:

“I’ll give him the grapes. Who knows, they may bring some joy to his life.”

And that is what he did. But the grapes didn’t stay in the sick monk’s room for long, for he reflected:

“The cook has looked after me for so long, feeding me only the best meals. I’m sure he will enjoy these.”

The cook was amazed at the beauty of the grapes. So perfect that no one would appreciate them more than the sexton; many at the monastery considered him a holy man, he would be best qualified to value this marvel of nature.

The sexton, in turn, gave the grapes as a gift to the youngest novice, that he might understand that the work of God is in the smallest details of Creation. When the novice received them, he remembered the first time he came to the monastery, and of the person who had opened the gates for him; it was that gesture which allowed him to be among this community of people who knew how to value the wonders of life.

And so, just before nightfall, he took the grapes to the monk at the gates.

– Eat and enjoy them – he said. – For you spend most of your time alone here, and these grapes will make you very happy.

The monk understood that the gift had been truly destined for him, and relished each of the grapes, before falling into a pleasant sleep.

Thus the circle was closed; the circle of happiness and joy, which always shines brightly around generous people.
