The project has supported use of indigenously designed and manufactured equipment such as Straddle Carriers, Launching Gantries, Bridge Gantries, and Girder Transporters for construction. This marks a first for Indian infrastructure, showcasing India's growing capabilities in high-speed rail technology with the support of the Japanese government

The adoption of the Full Span Launching Method has significantly accelerated construction, as full-span girder erection is up to ten (10) times faster than conventional segmental methods
India’s first Bullet Train corridor between Mumbai and Ahmedabad has reached a significant construction milestone with the successful completion of 300 km of viaducts. This achievement was marked by the launching of a 40 m long full-span box girder near Surat, Gujarat, according to the National High Speed Rail Corporation Limited (NHSRCL) statement.
Out of 300 km of superstructure, 257.4 km is constructed through Full Span Launching Method (FSLM) including 14 river bridges, 37.8 km through Span by Span (SBS), 0.9 km steel bridges (10 spans ranging from 60 to 130 m in 7 bridges), 1.2 km PSC bridges (20 spans ranging from 40 to 80 m in 5 bridges) and 2.7 km in station building.
