About TII Publications
TII maintains an online suite of technical publications, which is managed through this TII Publications website.
TII Publications are categorised as Standards or Technical. All documentation for implementation on National Road schemes is collectively referred to as TII Publications (Standards). All other documentation within the system is collectively referred to as TII Publications (Technical).
Documents within TII Publications are assigned attributes to allow for the documents to be easily searched on the website. These attributes are provided on the inside cover of each current document, for reference.
To maintain continuity between TII Publications and the old NRA Standards system, pre-existing documents within the NRA DMRB and MCDRW have been assigned a 'historical reference' so that existing documents and drawings can be searched using the old document names.
The TII Publication Number now supersedes the historical reference for all such documents. All historical references within the documentation are deemed to be replaced by the TII Publication Number.
For migration of documents to TII Publications, each existing document was given a TII front and rear cover. Within the TII covers, the contents of the documents are the same as in the previous NRA DMRB and NRA MCDRW system.
