How is the Quang Ngai - Hoai Nhon Expressway after 22 months of construction?

Overcoming adverse weather conditions, 9 million cubic meters of roadbed was still built

According to Giao Thong Newspaper's reporter, at the XL1 package, contractor Dacinco took advantage of the sunny and clear weather to speed up construction.

This is the contract package with the largest volume of filled soil with over 5.1 million m3. Right at the beginning of the route, this contractor basically completed the K95 soil layer, and the road has gradually appeared.

In addition to filling the K95 roadbed, Deo Ca contractor uses rocks to fill the K95 and K98 roadbed.

Trucks carrying materials from Nui Be and Hanh Duc mines continuously dumped soil onto the roadbed. Bulldozers advanced to level the road, rollers followed closely behind, the entire construction site filled with the sound of machines.

The contractor representative said that due to the erratic rainy weather, roadbed construction encountered more obstacles.

"During the rainy season, roadbed construction is very difficult, but we still take advantage of the sunny days to speed up roadbed work, making up for unachieved output to ensure completion of the earthwork as planned," said a contractor representative.

Along the roadbed, K95 soil is continuously added, and K98 is being built in some sections. Up to now, the XL1 package has built more than 3.1 million m3 of soil, equivalent to more than 63%.

Taking advantage of favorable weather, contractors started filling the foundation.

It is known that to speed up the progress and make up for the delayed output due to the late handover of the site and the newly cleared material mine, the contractor has arranged 11 construction points along the route with nearly 1,100 personnel and 449 locomotives and equipment. At the same time, 2 field laboratories and 8 joint laboratories have been mobilized.

Along the project site through the XL2 and XL3 packages, the roadbed embankment work is more stable as most of it has been upgraded to K95 layer. From Km 48 to Km 55, in addition to earthwork, the Deo Ca contractor is constructing K95 embankment and filling with granular materials using tunnel-bored rock.

The representative of Project Management Board 2 said that up to now, the project's roadbed construction has reached more than 9 million m3 out of a total of 10.6 million m3 of soil and about 700 thousand m3 of sand. Despite the unfavorable weather, the contractors still maintain the construction schedule. In particular, taking advantage of the clear weather and dry material mines, they have arranged enough manpower to construct the roadbed.

The total amount of soil, sand and other materials used in the Quang Ngai - Hoai Nhon expressway construction site is more than 10 million m3.

"In addition to earth filling, contractors are filling with K95 and K98 granular materials with an output of about 116,000 m3. The progress of roadbed construction, quality management, progress, labor safety, traffic safety, environmental sanitation... ensure the requirements on quality and the proposed plan," said the investor representative.

Speed ​​up construction of mountain tunnel system

At tunnels 1 and 2, which are 610m and 700m long respectively, the construction progress of the roadbed and concrete tunnel lining is being accelerated by the Deo Ca contractor. The contractor representative said that they are focusing on completing the tunnel lining, roadbed, and equipment installed in the tunnel...

At tunnel number 3, the contractor has arranged many modern drilling machines, and human resources are on site 24/7 to organize the construction. The construction atmosphere is always busy, the sound of drilling machines, bulldozers, and excavators echoes continuously.

Construction work on tunnel number 3 is being accelerated by contractor Deo Ca in the context of the rainy season.

For the southern tunnel construction site alone, located in Binh Dinh province, the contractor has arranged 322 personnel and 146 machines and equipment to organize the construction. Despite the complicated construction conditions and narrow site, the workers and engineers still strive to stick to each task.

Up to now, the right tunnel branch south of tunnel No. 3 has been dug 1,000m, contributing to increasing the total length of tunnel No. 3 dug for both tunnel tubes to nearly 3,800m out of a total length of 6,400m (reaching more than 58% of the volume).

"This is an important milestone in the overall progress of the project, and the contractor is making continuous efforts to open the tunnel on April 30, 2025," the contractor representative affirmed.

Not only the tunnel , the construction of the system of more than 500 bridges and culverts on the route has also changed clearly. Many bridges have begun installing girders, with construction reaching over 70%.

For the Song Ve bridge project, which is more than 600m long, the largest bridge project on the route, the contractor has completed pouring concrete for the bridge deck.

Deo Ca Group is striving to complete both tunnels No. 1 and No. 2 in 2024.

According to the leader of Deo Ca Group, the target by the end of 2024 is for the unit to reach about 61% of the total output of the project. Of which, completing tunnels No. 1 and No. 2, completing 63/77 bridges. Organizing asphalt concrete paving simultaneously on all 3 packages...

Nearly half of the project capital has been disbursed.

To ensure project progress, capital disbursement plan and especially to complete the project in 2025, 6 months ahead of schedule as launched by the Prime Minister "500 days and nights competing to complete 3,000km of expressway", the joint venture of contractors has increased the construction team, personnel and equipment to the construction site.

After 22 months of construction, the Quang Ngai - Hoai Nhon expressway has disbursed more than 6 trillion VND in construction capital.

At the same time, cut and transfer items of subcontractors that are behind schedule to "rescue".

It is known that currently at the construction site, the contractor has arranged 44 construction teams with 1,790 machines, equipment and more than 4,000 personnel.

A representative of Project Management Board 2 said that after 22 months of construction, the project's progress has reached more than 45%. Of which, most of the roadbed earthwork has been basically completed, other main items have also accelerated, and output has increased every day.

Investors and contractors are aiming to disburse all VND8,000 billion in construction capital in 2024.

"Although the progress is slow, in general, the work is still going smoothly and the contractor is speeding up, so in the remaining months, they will compensate for the slow volume, ensure the construction and disbursement plan of the project in 2024, creating a foundation for the project's completion in 2025," said the investor's representative.

Quang Ngai - Hoai Nhon Expressway is one of 12 component projects that started construction in early 2023. This is the project with the largest investment capital of more than 20,400 billion VND, spanning two provinces, Quang Ngai and Binh Dinh, with a length of 88km.
