Conceptual Site Models


According to BS10175, a conceptual site model (CSM) identifying all the potential contaminant linkages should underpin each stage of a site investigation and drive the risk assessment process.

Land Quality Management Ltd (LQM) created KeyCSM with Keynetix Ltd  in 2008 to allow contaminated land practitioners to rapid create and update conceptual site models.  The software is now unsupported but is still available as legacy software on the understanding that there are some known bugs that will need to be worked around.

KeyCSM in actionThe aim of the software is to speed up, ease and simplify the creation of conceptual models - a requirement of BS10175 - and to increase the quality of CSMs currently produced in contaminated land reports. The software combines a sophisticated drawing package with a database that links the various elements of the pollutant linkages at a site; the sources/contaminants, pathways and receptors. Dynamic links between the drawing package and database result in better models and make updating the model simple as the site progresses from desk study through the various stages of site investigation, risk management and validation.

Amongst its many capabilities, KeyCSM can be used to create detailed plans, cross sections, network diagrams and matrix diagrams to represent the sources, pathways and receptors associated with a potentially contaminated site.

The software is sold on the basis that purchasers understand the software contains bugs. Details of the known bugs are here

The software is available for computers running Windows.  It is not available for mac or linux machines.
