The goal of this paper is providing a methodology properly supporting façade optimization in a DfMA (Design for Manufacturing and Assembly) perspective. DfMA has proven to facilitate offsite manufacturing, lowering costs and improving speed and quality of construction, especially combined with BIM strategies. A BIM-based methodology can help in setting parameters for the proper optimization of the façade, balancing production related needs and design requirements. The proposed method allows the exploration of alternatives (known as Design Optioneering) to optimize the choice of façade elements. This method is based on a mathematical algorithm and script including parameters related to geometry, production waste management and designer's needs. The proposed methodology has been tested on a newly built school in Northern Italy.

The purpose of the paper is to investigate the state of the art of textual translation theories, methods, and tools into formal and numerical requirements to support information modelling and project management process. Natural Language Processing helps translate text requirements into numerical terms that are necessary for the application and success of information modelling and management in a datadriven process.

This research work aims at providing a methodological approach tested on a real case study, where a public university applied guidelines to structure BIM and IMM procedures. The research allows the public client to procure works and services to manage the portfolio. The approach is initially tested on the ABC department to be gradually extended to the entire Politecnico di Milano.

The research aims to implement Blockchain in Smart Contract in the design phase to reduce the financial exposition of SMEs. The adoption of Smart Contract, streamlining and accelerating the payments, shows up as a potential revolution of the traditional contractual framework. However, due to the increasing fragmentation and project complexity, the AECO sector is accused of slowness in accommodating and propagating new technologies. The Smart Contract can embed a Blockchain protocol that executes the predefined and agreed clauses by the contracting parties automatically and autonomously. It is a smooth and predictable data-driven process in which, at the after each clause, the payment is automatically issued, ensuring the shortening of payments. In the construction sector, the transaction delay represents a relevant problem that is responsible for disputes and economic disadvantages for the SMEs. Therefore, the paper investigates the process of digitalization starting from Smart Contract. The research is applied to the design phase developed in a BIM environment, pointing out both the advantages and the limitations, especially in the actual legislation. The Smart Contract features allow the entire supply chain to be protected against insolvencies due to late payments, improving process efficiency, and reducing payout times. From the results obtained in this research, the approach could be applied to a real case study and extended to the overall construction process.

In the digital transformation process of the construction sector, the Client has a crucial role involving all the stakeholders and organizing workflows with a digital platform that ensure the flow of information in a fluid and coherent way. Collaboration becomes a key factor in making the process work the best way and supports BIM throughout the building's lifecycle. For this reason, the Framework Alliance Contract has been applied, for the first time in Italy, on a case study (the new School of Liscate). The construction process has been supported by a collaborative platform linked to the BIM model that allows the traceability and real-time control of the consistency and accuracy of project information.
