The Prolam Specifier has been specifically developed to help designers, builders and specifiers design structural timber elements and specify glulam beams, portals and posts with greater speed, confidence and ease.
Developed by Prolam NZ, the online platform provides a faster alternative to working through span tables for structural timber calculations.
Covering a wide range of standard structural timber applications, the Prolam Specifier allows users to perform design calculations, adjust parameters and fine-tune member selections to identify suitable solutions for their projects. The system has been designed to simplify the specification process while helping users save time across design and documentation stages.
Alongside simplifying structural timber calculations, the platform also assists with building code compliance by generating documentation suitable for PS1 certification requirements, helping streamline supporting paperwork and specification workflows.

Prolam says the Specifier was originally developed in response to industry demand for a quicker and easier way to specify glulam timber systems without relying heavily on manual span tables or requiring engineering involvement for straightforward applications. What began as a PDF-based calculation tool in 2008 evolved into an online platform in 2014 and continues to develop based on feedback from users and specifiers.
For projects that extend beyond the platform’s standard calculation scope, users can also access Prolam’s Design Service directly through the Specifier platform, providing seamless access to Prolam’s engineering team for more specialised structural solutions and specific engineering design requirements.
As engineered timber continues to grow in popularity across residential and commercial construction, digital tools that simplify specification and compliance are becoming increasingly valuable for both designers and builders working under tighter project timelines.
