Manufacture and installation of the ALSA logo in dimensional letters on a building facade. The work included surveying the substrate, setting out at full scale, resolving the fixing method to suit the wall construction and installing with piece-by-piece levelling. The sign was handed over with fixings concealed and edges finished, ready for permanent outdoor exposure.
The challenge
Dimensional letters on a facade expose every deviation: a millimetre out of level or an irregular gap between characters is enough for the sign to read crooked from the street. The substrate also dictates the fixing method and requires a solution with no visible ironmongery.
Our solution
The letters were fabricated with lacquered sheet faces and returns, with the edge welded and dressed to avoid sharp arrises and water ingress. On site we set out with a full-scale template, marking the axis of each character and its drilling points; we then drilled, fitted chemical anchors and mounted the studs. The letters stand off the wall on concealed spacers, leaving a ventilation gap and preventing moisture from being trapped behind them. Each piece was levelled and the baseline of the whole sign checked before final tightening.
Materials used
- Dimensional letters in lacquered sheet with welded edge
- Full-scale set-out template on the facade
- Concealed fixing with studs and chemical anchors
- Spacers creating a ventilation gap behind the letters
- Exterior lacquer resistant to weather and solar radiation
Results
- Logo aligned on a continuous, level baseline
- Regular letter spacing, faithful to the brand original
- Fixing with no ironmongery visible on the wall
- Ventilation gap that prevents trapped moisture
- Sign readable from the approach to the building
