Linear Referencing in QGIS?

I work for a survey company doing gas lines GIS. We use QGIS.

We create hand drawn sketches of pipelines containing all sorts of information including: materials used, skew numbers of equipment installed, exact location from a datum ( 0 point), etc. what we would like to do is use QGIS to replace the hand drawn portion of the job. Basically, create, in the GIS program, the drawing, have symbology present each pipe/material location and be able to select that location and have a dialog box populate with the location attributes: skew numbers, material used in that exact local.

Are there any plugins for this?
