SCALE produces structural engineers' calculations and component details for the design of a variety of components such as beams, columns and slabs, using steel, concrete, masonry and timber. SCALE outputs pdf and docx files, consisting of a set of pages, neatly titled, dated and numbered, containing calculations and component details made to a standard suitable for submission to a checking authority. “I use SCALE because it produces neatly composed calculation sheets which can easily be checked.” SCALE incorporates a library of over 600 proforma calculations, which are accessed via in-app subscription. The content of this library is continually under review, proformas being added or modified as codes of practice develop and change. All proformas include a parallel set of calculations for Eurocodes and British Standards. “I would like to express my thanks for the many years of use of your excellent design software which has made my life so much easier.” SCALE includes LUCID and SPADE, 'expert systems’ which know about reinforced concrete, steelwork, timber and masonry detailing, and build the detail using the knowledge contained within their databases. “I am self employed and use SCALE everyday for design. I have also used your LUCID automatic reinforcement detailing / bar schedule for ground beams and use the automatic steel connection detailing program. I have never had any queries on either of these from site.” SCALE includes NL-STRESS for 2D/3D elastic analysis with linking between analysis and design, non-linear (plastic and stability) analysis, and numerous pre and post-processors for vehicle loads, guyed masts etc. SCALE users produce over one million pages of structural calculations per year; SCALE has condensed print and summary options for saving paper.
