Project Year: 2004

The project involves a two level composite concrete and steel truss bridge crossing River Brahmaputra in Assam. Total length of the bridge is about 4.2 km.

The project includes:

Superstructure: The proposed new Rail cum Road Bridge carries a double track railway on the lower level and tree lane road with footways on the upper level, the concrete deck. The detailed design comprises of two typical spans:

  • A standard span of 121.6 m lenth (centreline-centreline bearings) and an end span of 30.0 m length.
  • Distance between centreline-centreline span truss plane is 11.0 m.
  • Total height of the bridge is 12.5 m

Substructure: The substructure at every pier location comprises twin circular hollow columns (each of 3.0meter in diameter with 1.0 meter wall thickness) connected together at the top by a pier cap 7.0 m wide x 17.6 m long x 1.2m thick.

Consulting Services provided for the project include:

  • Preparing of Design Basis Note
  • Detailed Design for the Superstructure
  • Procedures for fabrication and erection works
  • Specifications for Tender documents and Operational and Maintenance Manual

Detailed Design for construction of 335Meter long bridge across river Watrak near Kheda https://lntiel.com/index.php/detailed-design-for-construction-of-335meter-long-bridge-across-river-watrak-near-kheda/ https://lntiel.com/index.php/detailed-design-for-construction-of-335meter-long-bridge-across-river-watrak-near-kheda/#respond Mon, 09 Mar 2015 06:15:51 +0000 http://lntiel.com/?p=3566 Client: L&T Engineering Construction and Contracts Division (ECC)
Project Year: 1999

Bridge across river Watrak near Kheda, Gujarat on NH8 on the Ahmedabad – Vadodara National Highway, was set up under Build-Own-Operate-Transfer scheme.  In addition to the high level bridge, this link consists of a one-way two-lane carriageway stretching for 9.2 km.

L&T Infra Engineering is providing engineering services for the bridge and the approach roads.

The scope of work involves providing Consultancy Services for Detailed Design of construction of a two lane bridge across river Watrak near Kheda, including 9.2 Km approach road and strengthening of NH-8.  The Project consists of 42.2 M span pre-stressed concrete I-girders completely precast and launched in position over single circular piers on well foundations. The well for foundation was sunk by jacking down method. The work done included the complete design of bridge and cross drainage works along the 7 Km long approaches to the bridge and obtaining approval for the same from the owner’s consultants. The abutment is of spill through type of height 8m.

Consulting Services provided for the project include:

  • Ground Surveys & Investigation
  • Material surveys
  • Geotechnical investigation for bridges and high embankments
