BEP Guide - Version 2.2 - PennState College of Engineering
[1]
PennState College of Engineering released a 2019 update of the BIM Project Planning Guide [BEP] version 2.2. [2] As a summary of the bim.psu.edu publication, I used quotes that best describe the entire document: The Building Information Model (BIM) is "a digital representation of the physical and functional characteristics of an object." To successfully implement BIM, the project team must carry out detailed and comprehensive planning. This Project Planning Guide on Building Information Modeling (BIM) is aimed at readers with a basic understanding of BIM concepts; To successfully integrate BIM into the project delivery process, it is important for the team to develop a detailed BIM implementation plan. The BIM Project Delivery Plan ("BIM Plan") provides an overall vision with implementation details for the team to follow throughout the project. In developing a BIM Plan, members of the project and project team can achieve the following value: 1. All parties will clearly understand and communicate the strategic goals for implementing BIM in the project 2. Organizations will understand their roles and responsibilities in implementing 3. The team will be able to design an implementation process that will well adapted to the business practices of each team member and typical work organization. 4. The plan will identify additional resources, training, or other competencies necessary to successfully implement BIM for the intended applications. the plan will provide a reference point for describing the process to future participants who will join the project. 6. Purchasing departments will be able to define the language of the contract to make sure that all project participants fulfill their obligations. 7. The baseline will define the goal of ensuring progress throughout the project; One of the most important steps in the planning process is to clearly define the potential value of BIM in the project and for members of the project team by defining overall BIM implementation goals. These goals can be based on project results and include things like reducing schedule times, achieving higher field productivity, increasing quality, reducing job change costs, and acquiring important operational data for a facility; The twenty-five identified uses are not exhaustive, but provide a good representation of current BIM uses in the industry; This will include the definition of the delivery structure and the contract language; defining communication procedures; defining technological infrastructure; and defining quality control procedures to ensure high-quality information models.
What information is included in the BIM Project Execution Plan ? - General information about the BIM project execution plan: Document the reason for creating the project execution plan; The plan should contain critical project information such as project numbers, project location, project description, and critical schedule dates for future reference; Key contact persons in the project; BIM goals: in this section, document the strategic value and specific uses of BIM in the project; Collaboration procedures: The team should develop procedures for electronic activities and collaboration. This includes the definition of model management procedures (eg, file structures and file permissions) as well as typical meeting schedules and agendas; Technological infrastructure needs: Define the hardware, software and network infrastructure required to execute the plan; Model structure: the team should discuss and document such elements as model structure, file naming structure, coordinate system and modeling standards; Delivery strategy / contracts;
To develop a BIM plan, a planning team should be assembled early in the project. This team should be composed of representatives from all major members of the design team, including owner, designers, contractors, engineers, specialist major contractors, facility manager and project owner. It is very important for the owner as well as all the main team members to fully support the planning process; Once this initial goal setting is complete, detailed implementation and information exchange processes can be developed and implemented by lead BIM coordinators for each party; A BIM plan for a project cannot be developed separately. None of the parties on the project team can adequately outline the execution plan while still getting the team member commitments needed to successfully implement BIM. To have a successful BIM project; The first step in developing a BIM project execution plan is to identify appropriate BIM applications based on the project and team goals; Before identifying BIM uses, the project team should outline the project's goals with their potential relationship with the implementation of BIM. These project objectives should be project specific, measurable, and aim to improve success in the planning, design, construction and operation of the facility. One category of objectives can address the overall performance of the project, including reducing the duration of the project schedule, reducing project costs, or increasing the overall quality of the project; Once each BIM application has been identified, it is imperative that you understand the implementation process for each BIM application and the project implementation process as a whole;
BIM Mission and Goals: The organization should establish a BIM mission; BIM applications; BIM process maps; BIM information exchange; BIM infrastructure; Development of a BIM project execution plan
Using BIM - the most important part of the guide has been briefly presented
B-1: Building maintenance schedule - The process by which the functionality of the building structure (walls, floors, roof, etc.) and its operating equipment (mechanical, electrical, plumbing, etc.)
B-2: Building Systems Analysis - A process that measures how a building's performance compares to a specific project. This includes how the mechanical system works and how much energy the building consumes.
B-3: Asset Management - A process by which an organized management system is bi-directionally linked to a record model to effectively assist in the maintenance and operation of the facility and its assets.
B-4: Space Management - A process by which BIM is used to efficiently distribute, manage, and track the appropriate spaces and related resources within a facility.
B-5: Emergency Management - A process by which rescuers would have access to critical building information in the form of a model and information system.
B-6: Record Modeling - The record model should contain, as a minimum, information on major architectural, structural, and MEP features. It is the culmination of all BIM modeling throughout the project, including linking operation, maintenance and asset data to an as-built model (built from project coordination, construction, 4D models and subcontracting manufacturing models) to deliver a record model to the facility owner or manager
B-7: Site Use Planning - A process by which BIM is used to graphically represent both permanent and temporary facilities on a construction site during multiple phases of the construction process.
B-8: Structural System Design - A process in which 3D system design software is used to design and analyze the structure of building systems (e.g., formwork, glazing, anchors, etc.)
B-9: Digital Manufacturing - A process that uses digitized information to facilitate the production of structural materials or assemblies.
B-10: 3D Control and Planning - An example of this is wall layout using a total station with preloaded points and / or using GPS coordinates to determine if the appropriate trench depth has been reached.
B-11: 3D Coordination - A process where Clash Detection software is used during the coordination process to identify terrain conflicts by comparing 3D models of building systems.
B-12: Design - where 3D software is used to develop a building information model based on criteria that are important in translating the building design
B-13: Technical Analysis - These analytical tools and performance simulations can significantly improve facility design and energy consumption during the life cycle in the future.
B-14: Energy Analysis - Object Energy Consumption BIM analysis is a process during the facility design phase in which one or more building energy simulation software uses a tailored BIM model to perform energy assessments for the current building design.
B-15: Structural Analysis - A process by which analytical modeling software uses a proprietary BIM model to determine the behavior of a given structural system.
B-16: Lighting Analysis - Use the model to perform a quantitative and aesthetic overview of lighting conditions in a space or over a surface or series of surfaces. This may include daylight analysis or artificial lighting analysis.
B-17: Sustainability Analysis - Process by which a BIM design is assessed against LEED
B-18: Code Validation - The process by which code validation software is used to validate model parameters against project specific codes. Code validation is currently in its early stage of development in the US and not widely used. However, as model validation tools develop, software to validate code against more codes, code validation should become more widespread in the design industry.
B-19: Design Review - The process by which stakeholders review the 3D model and message provide feedback to test many aspects of the project. These aspects include evaluating program fulfillment, previewing the aesthetics and layout of the space in a virtual environment, and establishing criteria such as layout, visibility, lighting, safety, ergonomics, acoustics, textures and colors, etc. This BIM use can be done using a computer. software only or with special virtual mockup devices such as CAVE (Computer Assisted Virtual Environment) and immersive lab. Virtual mock-ups can be made at different levels of detail depending on the project needs.
B-20: Programming - The developed BIM model enables the design team to analyze space and understand the complexity of space standards and regulations. Critical decisions are made at this stage of the design and bring the greatest value to the project when the needs and options are discussed with the client and the best approach is analyzed.
B-21: Site Analysis - The process by which BIM / GIS tools are used to assess the properties of a site to determine the most optimal site location for a future project. The collected location data is used first to select a location and then to position the building based on other criteria.
B-22: Phase Planning (4D Modeling) - Process by which a 4D model (3D models with an additional time dimension)
B-23: Cost Estimation - Takeoff Quantity
B-24: Existing Conditions Modeling - A process by which the design team develops a 3D model of existing conditions for a site, site features, or a specific area within a facility.
