Dynamic Software for Sign Post and Foundation Design

KeyPOST is a standalone sign structure software program that provides for the design of sign installations. It can also be used in combination with our leading KeySIGN sign face design software. Whilst many will use the AutoPost feature that suggests the most economical structure, it can also be used to test their stability against the effects of wind loading by providing for existing structures to be modelled and tested, for example for additional or replacement signs.

KeyPOST is fully accredited by BSI, as a European Notified Body, to EN 12899-1:2007. It also enables you to design structures compliant with EN 12767:2019, all relevant Eurocodes, including EN 1991-1-4:2005 for wind loads, and, in the UK, relevant DMRB Standards.

KeyPOST provides full support for BIM and 3D when used with our design products such as KeySIGN and KeyLINES. It includes the ability to incorporate the sign face design with your proposals to create a 3D sign structure in KeyLINES, for example. In addition, you can author the data associated with the 3D sign structure to share with other BIM applications, such as Navisworks.
