The BIM Execution Plan (BEP) is an essential document, drafted with the aim of providing a reference framework to effectively conduct the building project and optimize the workflow.

It consists of two distinct phases:

• The pre-contract BIM Execution Plan (BEP Pre-contract) is a document prepared by potential suppliers in which a specific proposal for the development of the building project is exposed. It aims to describe the skills, key decisions and working methods that are intended to be taken during the entire construction project phases to meet the client’s needs and goals. Furthermore, it designates the operators who will take part in the process, and specifies the responsibilities and information requested in the essential stages of the project. The pre-contractual BIM Execution Plan (BEP) also includes the Project Implementation Plan (PIP – Project Implementation Plan). This is a document that must be presented by each organization that competes to participate in the project and includes the assessment of the supplier about its competence, the information technology which will guarantee the efficiency of the BIM process, the experience, and the resources that its organization possesses. Part of the pre-contractual BIM (BEP) Execution Plan is the Delivery strategy of the project information model (PIM – Project Information Model). The pre-BEP is drafted taking into consideration a document called “Employer’s Information Requirements (EIR)“. This is a fundamental source of information since it describes the information requirements of the client. Specifically, it outlines the information to be delivered regarding key decisions, standards and the methods of collaboration required to ensure that the solution presented effectively meets the customer’s needs.

• After the award of the project, the post-contract BIM Execution Plan (BEP post-contract) will be drawn up to facilitate the management of the building project. This is an interactive process, to which all the actors of the supply chain will gradually take part. It includes the contract that confirms compliance with the requirements of the Employer’s Information Requirements (EIR). Basically, at the management level, it must include the roles, responsibilities, and authority of each professional, the main stages of the process, the definition of collaboration processes and information modeling, the delivery strategy and the compliance with the standards. A review of the project implementation plan (PIP – Project Implementation Plan) must also be stated. the BIM Execution Plan (BEP post-contract) also includes the so-called “Matrix of the responsibilities of the entire supply chain, a tool that clearly defines the responsibilities for producing information and models for each project phase. The production of information delivery (MIDP – Master Information Delivery Plan) and the Plan of information distribution activities (TIDP – Task Information Delivery Plan) are fundamental parts of this phase. In the first case, the objective of the document is to deliver the information necessary for the development of the construction project such as those related to models, drawings, specifications, software, etc. In the second case, it refers to a series of documents to be provided for each activity, including format, date, and responsibility.

Advantages of BIM

During the last decade, BIM has gained popularity within the AEC industry as it has developed a prototype of an intelligent virtual building that involves the design, operational construction, maintenance, and eventual demolition phases. In fact, the great advantage of BIM is that the digital simulation of the project is created before laying the first brick. The BIM, therefore, minimizes errors, allows fast calculations, quantifies extra costs and alternative scenarios.

Thanks to the BIM execution plan, all team members must understand the project objectives and the end uses of the BIM model in order to configure it correctly. The objective, during the research phase, is to propose an efficient offer both from the economic and the resources point of view, without forgetting compliance with the standards. The coordinated organization of the activities promotes interoperability, allowing the reduction of the budget (through less waste), an improvement in the quality of the design, and the simplification of communication, amongst other benefits.

Trace Software International Software Solutions

The digitalization of the building industry is having an impact on both electricity and energy markets. We have conceived two software solutions able to leverage the benefits of BIM.

elec calc™ BIM is the first software in the world that perfectly integrates the electrical calculation into the Open BIM process. With elec calc™ BIM, the user can design, calculate and size the electrical installation in the digital model in IFC 4 format, generated by any 3D architecture software (Revit, ArchiCAD, SketchUp …). The software can connect to the BIM&CO platform to access manufacturer data.

archelios™ O&M is the monitoring software for any PV installation. It brings all the benefits of the PVBIM digital model for advanced operation and maintenance.
