the drawing becomes the object.

The t is the initial of traceability and of trazabilidad: the same letter in both languages we work in. Traceability is the ability to identify the origin and every stage of a process; at t1x1 it applies to every line — where it comes from, which decision holds it, what it builds.

Scale 1:1: the point at which the drawing stops representing and coincides with what is built. And a module of 1.00 × 1.00 m, the common measure that lets a chair, a house and a city be drawn with the same rigour. Every project, from idea to site, in the same hands.

In Spanish, traza means both the design of a work and the mark something leaves behind. To design with traceability is to join the two: deciding the form and leaving a record of every decision, so that any line can be followed back to its origin. The easier it becomes to produce, the more that matters.

In software, source code is the readable text from which everything else is generated: programs are recompiled; the source is kept and reviewed. In a project, the record of the trace does that job — every line with its origin, its reason and its measure. Drawings, models, renders and the building itself are compilations of that source; the tools, from the drawing board to CAD and information models, are the compilers, and they will keep changing. That is why t1x1 is defined by its source and not by its tools: a trace written with rigour stays legible when the instruments change, and someone always answers for it.
