The Authority for the supervision of public works contracts, services and supplies issued a guidance document useful for the preparation of DUVRI also for private contracts.
the Italian Official Gazette of March 15, 2008 was published in fact the determination No 3 / 2008 of the Authority with valuable information about the preparation of this single risk assessment (DUVRI) and determination of security costs.
Interference
The DUVRI be drawn only if the risks are expected to occur during the performance of interference. In
DUVRI therefore should not be given the risks to the activity of individual contractors or self-employed individuals.
As an example consider the determination of the risks related to interfering overlapping of several activities carried by different contractors, the risks placed on the work of the principal contractor from working, existing risks in the workplace of the buyer, when and 'provided that the contractor must work, additional to those specific to its contractor; risks resulting from special requests execution mode explicitly by the client (which involve risks in addition to those specific to the sub-contracted) - 
DUVRI is not required in the mere delivery without installation, except for cases in which activities are necessary or procedures likely to generate interference with the actual supply, such as the delivery of materials and products in the workplace or on site (with the exception of those where the risks have been assessed interfering in the security plan and coordination, as detailed in below), for services covered and not 'planned execution within the contracting, meaning "Inside" any premises or site made available by them for providing the service, whether or not the seat of their offices, for services of intellectual nature, even if made with the awarding body. The
DUVRI is not required in the mere delivery without installation, except for cases in which activities are necessary or procedures likely to generate interference with the actual supply, such as the delivery of materials and products in the workplace or on site (with the exception of those where the risks have been assessed interfering in the security plan and coordination, as detailed in below), for services covered and not 'planned execution within the contracting, meaning "Inside" any premises or site made available by them for providing the service, whether or not the seat of their offices, for services of intellectual nature, even if made with the awarding body. The
DUVRI is not required on contracts within the scope of Legislative Decree No 494/1996, on which we must draw up the security plan and co-ordination as risk analysis and interfering the estimated costs are included in the security plan and coordination.
security costs for the quantification of security costs from interference, in analogy to works, you may refer point 4 of Annex XV to the text only.
The cost estimate must be fair and analytical (not absolutely certain what percentage of the amount of the contract).
When notice or negotiated charges relating to security should not be subject to reduction and should be disclosed separately from those subject to reduction of the auction.
Even if sub-contracting or subcontracting these costs should not suffer declines. The
DUVRI, if required, must be part of the contract.
