Unlike the urgent progress in Ba Ria - Vung Tau, the two packages No. 40 and 41 on the Dong Nai coast are facing many difficulties. Although the ground has been cleared, sand has been pumped and test piles have been drilled at some locations, the foundation work is still slow due to the scarcity of sand for filling. Up to now, the output has only reached about 1%.

According to the investor, in the Dong Nai packages, the contractor has mobilized machinery and equipment to construct the foundations while the site is not yet complete. Some locations are still waiting for completion of site clearance procedures and conversion of forest land use purposes. Currently, at the construction site, the contractors are mobilizing about 350 engineers, workers and many super-gravity cranes from 250 to 350 tons, tower cranes to ensure progress.
