TGSI Warning Indicators on Entry Ramp from DTAC![]() 11 Exhibition Street 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 TGSI's on the base of the stairs are set back 300 from each step (stair) interval section whilst the TGSI's at the top of the stair extended the full length of the accessible path.
