These days, on many bidding packages of the Dong Dang (Lang Son) - Tra Linh (Cao Bang) expressway, the construction atmosphere is still urgent.
Hundreds of excavators, bulldozers, dump trucks, and rollers operate continuously to level the roadbed, transport soil and rocks, and construct bridges and culverts.
Although the fuel market is experiencing many fluctuations due to the world situation, construction units at the construction site are still striving to maintain the pace of work to ensure the overall progress of the key traffic project in the Northeast region.
According to information from the inter-Ministry of Industry and Trade - Finance, domestic gasoline and oil prices have recently been adjusted to increase according to the developments of the world energy market.
This partly creates cost pressure for many production and construction sectors, including transport infrastructure projects.
At the Dong Dang - Tra Linh expressway construction site, fluctuations in prices and fuel supply have also begun to affect construction activities. However, contractors said they are still actively looking for many solutions to maintain progress.

Talking to reporters, Mr. Dang Tien Thang - General Director of Dong Dang - Tra Linh Expressway Joint Stock Company said that in recent days, access to gasoline and oil sources has been more difficult than before.
Machinery and manpower have been fully mobilized to the construction site. However, the source of gasoline and oil is sometimes quite tight, some gas stations sell limitedly or prioritize essential needs. Therefore, construction units must proactively seek more supply to ensure the operation of machinery," Mr. Thang shared.
According to representatives of the project enterprise, in the context of limited fuel supply at times, some contractors have flexibly sought to buy fuel at many different selling points to maintain construction.
Some units have to go to many places to buy small quantities to ensure that machinery is not stopped from operating. Despite facing certain difficulties, contractors are still trying to overcome them to maintain the construction pace," Mr. Thang added.
Also according to a construction unit on the route, a few days ago this unit had to buy gasoline and oil at a price difference of about 6,500 VND/liter compared to the listed price due to limited supply at some points of sale.
According to information from the project enterprise, fuel is one of the important input costs in the expressway construction process.

For roadbed excavation and leveling items, diesel costs can account for 30% - 45% of the machine ca value, because mechanical equipment such as excavators, bulldozers, and rollers must operate continuously.
Meanwhile, for bridge construction items such as boring piles, beam casting, and structural installation, fuel costs usually account for about 15% - 25% of the machine ca value, because many devices use electricity or have longer waiting times between stages.
Currently, the Dong Dang - Tra Linh expressway project is entering the peak construction phase with a large volume of work.
Every day, construction sites need to consume a large amount of diesel oil to operate machinery systems serving excavation, transportation of materials and roadbed construction.
Faced with fluctuations in the fuel market, contractors are proactively adjusting machinery operation plans, taking advantage of reserve fuel sources and finding more legitimate sources of supply to maintain construction.
According to construction units, despite facing pressure on fuel costs, contractors are still making efforts to overcome difficulties, coordinating with project businesses to ensure the overall progress of the project.
Dong Dang - Tra Linh expressway is an important transportation project of the Northeast region, connecting Lang Son province with Cao Bang.
When completed, the road will shorten travel time between localities, while creating motivation to promote socio-economic development and trade in the border area.
