The archaeological sounding carried out on the outer surface of Trajanic galleries 20A and 20B entailed, as a preliminary phase, the removal of all the weeds that had taken root in the layer of earth above the screed connecting and covering the vaults.
The types of plants which presented the greatest problems for the wall structure and that were most difficult to remove and eradicate were an Ailanthus altissima (ailanthus or tree of heaven) and a large Laurus nobilis (laurel) bush.
We have recently been working hard to organize the new works and in particular to prepare the projects to appropriate the funds which are still available. The procedures specified in the Code of Public Contracts both for direct commissions under the permitted limit and for tenders are fairly complex and require that we respect very specific phases and time frames. This means that the time that passes between the development of a project and the start of work is relatively long.
