Project description
What matters to me most is that the plates are actually readable by hand, not just decorative. Please tell me in your proposal what dot height and what dot spacing you use, what line spacing you keep between the raised text and the Braille line, how you keep the dots from flattening after months of being touched, and what the character height of the raised letters will be. The surface must be matte, with no glare under our ceiling lights, and the sign must have strong contrast between the character and the background — our corridors are not brightly lit. The material should survive daily wiping with a damp cloth and mild disinfectant without the letters lifting or the colour fading.
Please also state the mounting height you plan to use, which side of the door the plate goes on, and how you handle doors that open outward or have narrow frames. Add pictograms where they help: entrance, toilets, lift, stairs, reception. I want to be clear about one thing: accessibility requirements are set by local regulations, so the exact figures must be checked against the edition currently in force, and the wording on the plates should be reviewed together with people who actually use such signs — their reading is worth more than my guess.
What I need from you:
— a layout for each of the 27 plates with the text and the Braille line shown;
— material, thickness and fixing method, with a sample plate before the full run;
— measured dot height, dot pitch and line spacing, written in the proposal;
— delivery and installation on site, in one visit if possible;
— a short handover note telling us how to clean the signs and what not to use on them.
