Tuesday marks the third and last day of the committee's meetings in Khartoum.
The tripartite committee has been discussing the joint technical offer by French consultancy firms BRL and Artelia.
Egypt had said the three countries received the technical offer in January to be studied and discussed by the tripartite committee.
A Sudanese official told MENA Monday that the first day's meetings ended on a positive note and that there was mutual understanding between the three parties about common interests.
The contracts with the two consultancies that will conduct impact studies of the dam should be signed early February, Egypt's foreign ministry said last month.
The technical committee was tasked in 2013 to choose consultancy firms to conduct a study on the social, economic, and environmental impact of the dam and a study on the dam's hydraulic effect on downstream countries Egypt and Sudan.
