Tactile Ground Surface Indicator Sheets Help Save on Installation Costs

When it came to renovating Northland School in Wellington, the choice of ALLTAC Sirius Tactile Ground Surface Indicators (TGSI) proved to be a game-changer. The installation of a 900 x 1200mm plate took 15 minutes, from unpacking to fully installed, compared to the industry standard of approximately 2.5 hours for traditional TGSI dots to cover the same size area.

Peter Shaw from McKenzie Higham Architects praised the effectiveness of the ALLTAC plate, stating, "The time and cost savings to the project were substantial, as was the ease of installation. We also anticipate fewer issues in the future, such as loose individual tactile indicator buttons requiring replacement."

The quick installation of these TGSI sheets offers a convenient solution for also placing them directly over existing damaged TGSI Dots, eliminating the need for expensive labour removal.

For footpaths, Safety Yellow is universally accepted and meets the luminance contrast requirements outlined in AS/NZS 1428.4.1:2009. However, by utilising ALLTAC Sirius sheets in Platinum you can achieve even higher luminance contrast of up to 55%. This increase is made possible by their LVR (Light Reflectance Value) of 72.00, when installed against a dark concrete background with an estimated highest LRV of 20. If the concrete has an LRV of only 10, the luminance contrast would be even greater, which makes it easier to pick up for the visually impaired, and therefore a safer system for those they designed to protect and support. You can use a simple calculator, available here, to determine the desired luminance contrast.
