Cao Lanh - An Huu Expressway: The only slab girder section will be completed in November

Completed in November

Cao Lanh - An Huu Expressway starts at the intersection with My An - Cao Lanh Expressway in Cao Lanh District, Dong Thap Province. Ends at the intersection with Trung Luong - My Thuan Expressway in Cai Be District, Tien Giang Province.

The only girder section on Cao Lanh - An Huu expressway, component project 1, section through Dong Thap province.

The project is divided into 2 component projects. Of which, component project 1, the section passing through Dong Thap province, has a length of 16km, a total investment of more than 3,600 billion VND and a construction period of 840 days.

The project is implemented by a joint venture of VNCN E&C Construction and Engineering Investment Joint Stock Company - Thien An Mechanical and Construction LLC and DACINCO Construction Investment LLC.

Mr. Phan Van Hanh, Project Manager, Thien An Mechanical and Construction Company Limited (contractor) said that the section implemented by the company is 3.5km long.

Workers are busy constructing and the floor beams are expected to be completed next November.

In addition to the construction of bridges and roads in the project, the contractor also carried out 680m of continuous floor beams. Up to this point, the floor beam section constructed by the contractor has completed 571m, reaching 84%.

"Currently, at the construction site, the company is arranging for workers to construct the 4-layer floor slab, pillars and the 4-layer floor slab. In October, the company will continue to complete another 33m of floor beams and it is expected that by the end of November, the contractor will complete the floor beam section according to regulations," Mr. Hanh added.

Construction solutions during the sand waiting period

Cao Lanh - An Huu Expressway, component project 1, the section through Dong Thap province started construction at the end of June 2023, but sand will not arrive at the construction site until mid-May 2024. Therefore, during the one year waiting for sand to arrive at the construction site to build the road, the contractor, in addition to constructing the bridges included in the project, will also carry out the continuous beam and slab section included in the design.

Construction of floor beams helps maintain progress while waiting for sand to fill the Cao Lanh - An Huu highway foundation.

Thanks to that, the project progress has been maintained stably and currently, the contractor is speeding up construction after 4 sand mines handed over by Dong Thap province under a special mechanism have been exploited.

Mr. Mai Ngoc Dien, consultant and supervisor of component project 1, Cao Lanh - An Huu expressway, section through Dong Thap province, said that compared to building a normal road, the cost of building a floor beam on the expressway is slightly higher.

However, in return, the construction of floor beams and site clearance work is lighter because the floor beams are constructed at a high altitude, and the land area used for construction is smaller than that of normal roads.

Floor beams also help maintenance and repair work to be lighter than conventional roads.

In addition, the floor beams are built with reinforced concrete. Therefore, in the face of the previous difficulty in sourcing sand for the foundation, the floor beams can still be constructed continuously, saving time waiting for the necessary materials for road construction.

"When building a normal road, although it costs less, the maintenance and repair work is more than making floor beams. Meanwhile, making floor beams on the expressway depends on the construction conditions and design of the project," Mr. Dien added.

The Cao Lanh - An Huu Expressway starts at the intersection with the My An - Cao Lanh Expressway in Cao Lanh District, Dong Thap Province. The end point is at the intersection with the Trung Luong - My Thuan Expressway in Cai Be District, Tien Giang Province.
Of which, component project 1 is 16km long, passing through Dong Thap province, with a total investment of over VND3,600 billion. Component project 2 is 11.4km long, located in Tien Giang and Dong Thap provinces, with an investment of over VND2,200 billion.
The scale of the completed phase cross-section meets the standards of a four-lane highway. The cross-section of phase 1 is divided into four lanes, with a roadbed width of 17m and an operating speed of 80km/h.
