This formula collection is the first of its kind specifically designed for professions in the construction sector. It is published in its first edition in 2016. By consistently focusing on the fundamental formulas, it has been intentionally kept compact and handy to ensure clarity and quick handling. If necessary, trainees can enter additional formulas on the designated pages. The work contains formulas and information that may appear in the intermediate and final examinations for the professions of construction specialist, screed layer, tile, slab, and mosaic layer, painter, plasterer, and drywall installer. It was created based on the examination task sets used in recent years.
