Construction Law/Omission of Works


Dear Sir,

Hope you are doing fine.

It has been so long since my question last time.

My question today is:

Whether an amendment to a sub-contracting agreement would be required if the main Contractor omits by mutual agreement certain, considerable rather, works? In fact, the agreement took place orally.

Or that a variation Order shall be signed?

What is the difference? Which one should be done- Variation Order or Amendment and how?

Being deeply indebted in advance to hearing your expert advice, as usual of course,  I remain


Hi Alemu,

Thanks for your trust as always.

To answer your question, neither amendment nor variation order shall be made as there was no agreement executed between the Contractor and Subcontractor.

A new agreement based on reduced scope of work shall be executed by both parties.

Regarding Amendment versus Variation Order. My personal opinion are as follows:

Variation Order - as defined in the contract (review it), shall be made in case of changes in quantity, quality, etc. Example: A room was previously having a ceramic tiles but the Engineer instructed to change it to marble, the same procedure applied on Main Contract may be used in Subcontract. This will also protect the cash flow of the Contractor, as he can only issue variation order to Subcontractor once a similar Variation Order is received from the Client. Similarly, the payment for such variation shall be made on back to back basis as well once the corresponding payment from the Client is received.

Amendment - shall be made when a scope based on original contract will be added to the agreement. Example: You have an existing marble and granite agreement that covers floors and walls. A granite counter top was then added as part of the agreement in a form of amendment.

However, this will depend on the existing procedure by your company. In case the variation and amendment  procedure is existing, you have to follow the same. Otherwise, you may create your own, based on the above information I have provided and agree it with your management as a standard guidelines to be used by your company in the future.

I hope this will address your query

Kind regards,
