Hi Hanna,
As indicated by Victoria, you can download and use the One Click LCA spreadsheet to share with contractors etc. There are also descriptions as to how should the data be provided, i.e. saying just concrete will almost never be sufficient enough.
When it comes down to material assemblies though, the level of detail depends on the requirements of the study you are conducting. For instance, LEED has a specific scope that, amongst others, excludes finishes. So, to sum things up, for general purpose you can use the template provided by One Click LCA but for more specific purposes you’d have to use it in tandem with the study’s scope of analysis.
Hope this helped!
