The National Highways Authority of India retained L&T Construction’s Transportation Infrastructure Independent Company to perform
detailed design for rehabilitation of the 148.3-kilometer stretch of NH 46 between Krishnagiri and Walajapet in Tamil Nadu, India. The INR
10. 63 billion project will widen the carriageway from four lanes to a six-lane divided carriageway.
With just six months to complete the design, the project team used Bentley MXROAD to optimize the alignment and quickly finalize the
design. Bentley software was used to create drawings for the main carriageway plan and profile, service road plan and profile, drainage
plan and profile, detailed junction design, and typical cross section drawings. Alignments were optimized based on geometry, completion
time, constructability, and cost. Automated design detailing helped to achieve the project goal.
L&T Construction’s Transportation Infrastructure Independent Company designed the rehabilitation, widening, and strengthening of a
244.12-kilometer stretch of NH 14 from Beawar to Pali in Rajasthan, India. The INR 8. 55 billion project converted a two-lane highway into a
four-lane divided highway under a design-build-finance-operate-transfer scheme. The project will reduce traffic congestion and accidents,
as well as improve access to major cities.
The National Highway Authority of India’s tight timeline for the project challenged the team to deliver the best possible design for the
hilly terrain while staying on schedule. The analysis tools in Bentley MXROAD allowed the engineers and designers to identify potential
problems during the design phase rather than incur the high cost of re-work on site.
