Peg marking for Airport Metro begins

The survey for the Airport Metro has been completed and peg marking of its alignment on the ground has started, stated MD, HAML Mr. NVS Reddy. Apart from the traditional engineering peg marks on the road, aluminum boards with retro-reflective sheets for nighttime visibility are also being embedded in the central median, etc., indicating the chainage i.e., a distance of that particular point from the starting point of Airport Metro, he explained.

While smaller size boards are being placed at every 100 meters as 0.1 km, 0.2 km, etc., slightly bigger boards are being kept at every half a km. The boards are placed in the central median from Raidurg to Biodiversity jn; and from IT Towers on Khajaguda road to Nanakramguda jn where the central median is available. From Nanakramguda jn to TSPA (APPA) jn they are being fixed on the footpath side as the service road on the city side of ORR is under expansion and as of now there is no central median in this stretch. However, Airport metro pillars will be located in the central median of the expanded service road between Nanakramguda jn and TSPA jn along the ORR, stated Mr. NVS Reddy.

Transferring the alignment onto the ground by peg marking will facilitate preliminary works such as marking of Airport metro pier (pillar) locations on the ground and taking up soil testing for determining the soil bearing capacity, designing piers, etc., he added.
