BIM IN CONSTRUCTION MIDTERM WITH VERIFIED SOLUTIONS.

Differences between CAD, BIM and VDC ? CAD (oldest method) = A design and documentation tool that uses computer technology to arrive at the most accurate, comprehensive and information-rich model within its parameters (aka a technological tool) BIM = a process of collaboration that is facilitated by the latest digital technology ; providing a holistic approach to construction that unifies design, building and documentation across a project's lifespan KEY DIFFERENCE between BIM and 3D CAD is that a BIM file is much more information-rich, and includes details of performance characteristics, specifications, and other non-physical data embedded in a shared 3D digital model of the project. VDC = like BIM is a process and a way of working that involves the management of integrated multidisciplinary performance models ; VDC emphasizes collaboration and integrated working, and BIM is frequently a valuable part of VDC..... BIM is a much more specific process than VDC, but both are essentially methods of planning and managing a project collaboratively ; VDC processes are workflows that incorporate the information model and integrate previously disconnected aspects of design and construction ; VDC ultimately seeks to bridge the gap between design, construction, and operations; to realize facilities that are dramatically less wasteful both in assembly and usage; and to create buildings that function to serve their occupants throughout the complete usage lifecycle Benefits of 3D Coordination with MEPF Contractors? 1. Allows users to view how all the elements of the architectural, structural and MEP system are coordinated with each other in 3D space, hence using this a tool to help find and resolve issues faster. 2. Helps diminish financial risk by eliminating problematic field installation. 3. Digitalizes the coordination process and makes it more efficiently for information to be exchanged. 4. Allows us to explore constructability ideas, concepts and sequencing 5. Allows the coordination information and technology to be transferred to the field and used as a tool to continue coordination with field personnel. Brainpower Read More Differences between Levels of Details (LODs) ? Uses the concept of development. What portion of detail is enclosed within a model element ; can be thought of as input to the element Look at pictures!! The use and benefits of using tools such as Autodesk BIM 360 GLUE, Procore Models and Coordination Issues during the construction phase of the projects ? Reference Class #1 and Class #5 Lectures. What is the need for VCD specifications and the type of requirements that should be listed in BIM contracts in order to successfully deliver the product ? The VDC specification is a document designed to describe the required end product, as well as the framework by which the final product will be developed. The VDC specification also describes the types of VDC products the contractor is required deliver. It is a supplement to the signed contract between the entities, and might vary depending on their relationship. Identify BIM goals, determine the succession and hierarchies of participants, specify delivery requirements, and identify the protocols project participants will use to support the model. Are BIM Execution Plans a direct response to the VDC Specifications? What is their purpose? The BIM Execution plan is a direct response to the VDC Specification and serves as a road map for the successful execution of the methodology. Why are workflows important in BIM and VDC processes? What countries around the world have the highest BIM adoption rates? USA, UK, Scandinavia, France, Singapore What is Navisworks and why is it used in the AEC industry? Reference Class #3 Lecture. -Navisworks is a 3D design collaboration tool that let's you import model from various design platforms to create an aggregated design for visualization and review. -Results in a virtual model in which you can navigate in real-time and create walkthroughs that allow better understanding of the design intent. -The virtual model can be shared with various teams to find and fix problems, allowing for a more efficient management and coordination of the project. What are some of the navigation tools available in Navisworks? Class #3 - Steering Wheels = • Orbit • Zoom • Pan • Rewind - Walking & Flying - Looking Around What purpose do workspaces have in Navisworks? Class #3 Workspaces controls the visibility and location of various windows on the screen. You can turn on the visibility of the windows that you often use and then save as a workspace. What features are included in Navisworks Manage? Class #3 - Publisher - Autodesk Rendering - TimeLiner - Animator and Scripter - Quantifications - Clash Detective What is the difference between search sets and selection sets? Class #4 Selection Sets: Created by selecting the objects first and then saving them in a set with a name. Search Sets: Lets you search and select object based on their properties and then save them as a set for future selection. What categories are under the find items tools in Navisworks? Class #4 Category: Allows you to select the category on which you want to base your search Property: Used to select the property that you want to search for based on the category you selected earlier Condition: Used to select the condition operator for the category and property selected earlier Value: Used to select the value of the property selected earlier What function does the appearance profiler have in Navisworks and what transformations are you able to do to the elements in the model ? Class #4 Lets you select objects and then assign color and transparency to them for ease for identification. You can select objects based on their properties or use a selection set or a search set already created in the current scene. The common appearance can also be exported and then imported in multiple files. - Selector Area: Property vs. Sets Understand the Procore Design Coordination Issues and the steps to successfully elevate issues to RFI? Class #5 Advantages of implementing BIM processes to a construction site ? - Efficiency & Effectiveness - Analysis - Experience Simulations - Documentation Reduces Coordination Issues - Decision Making - Facilities Management Improved Timelines & Cost Savings -Better Project Outcomes - Project Team Communication Clear and established Workflow
