TGSI stainless ribbed warning tactile indicators from DTAC were installed on a set of stairs adjacent to an ascending pathway gradient.
This project involves a main entry stair that accommodates an adjacent pathway on an ascending gradient.
This means that the stairs protrude out at various intervals. To meet certification with AS/NZS 1428 (2002), the TGSIs on the base of the stairs are set back 300 from each step (stair) interval section while the TGSIs at the top of the stair extended the full length of the accessible path.
