### Agents Design: Actors, Roles, and Actions
(ii) Monitor the progress of the works and promptly issue the necessary actions for their execution within the limits of the time and sums authorised. (iii) Communicate, as construction manager, to the financial institutions/investors in all the work progress states and interact with Tax Auditors and Design Architects to certify works and fiscal credits matured. * Sub-contractor (SC) is the firm carrying out the works, interacts mainly with the General Contractor both for receiving working orders and for payment issues, all invoicing is done to the General Contractor and does not claim credits. * Supplier is the entity that supplies materials. It deals with Sub-contractors or directly with GCs to procure materials for construction sites. * Design Architect (DA) are designers such as engineers and architects. It is responsible for producing all the technical material (e.g., reports and drawings) necessary for the intervention to comply with the regulations in force. They assess the technical aspects of the project. * Tax Auditor (TA). In the event of professional negligence or misapplication of the rules, the professionals and the technicians in charge of the asseverations and issuing the compliance certificates could be liable for the sums unduly used. In this regard, periodic checks are carried out by a Tax Auditor to ensure compliance with the constraints defined in the smart contracts. He also checks the results of financial transactions, including correct invoicing of expenses (Financial asseveration). In Table 2, we report who/what interacts with the system and with what roles, actions, and related assignments define specific tasks and responsibilities to achieve overall goals and ensure effective execution. * Role 1: Compliance Control Agent (CCA). This role is connected with the activity of the Tax Auditor's actor and comprises all the activities of checking and controlling fiscal and financial aspects. It also certifies all intermediate and final steps of credit maturation and liquidation, and it further controls that other professionals' invoices are correct and adherent to price-list approval. * Role 2: Construction Manager (CM).The General Contractor (GC) actor coordinates all administrative and operational activities on the construction site. This includes acting as a proxy for payments on behalf of the customer towards all players operating in \begin{table}

Table 2: Roles, actions, and related assignments are interdependent elements that contribute to defining and executing organisational tasks. the Superbonus process. This vital coordinating role must be considered to run all the processes smoothly. * Role 3. Director of Work (DoW). The Design Architect (DA) actor has the task of controlling the expenditure connected with the execution of the works through the accurate and timely compilation of the accounting documents, which are public acts to all effects of the law. He also ascertains and registers the facts producing expenditure. The DoW (i) checks if the work is performed according to the project, (ii) transfers the measurements made to the accounting ledger to define the progress of the expenditure. He must pay special attention to guarantee compliance with the Superbonus Designer prescriptions, particularly the laying of materials. As a result, the Director of Works holds accountability for both the quality and outcomes of the work. * Role 4. Checker Work (CW).
