The AEC industry is seeing more clients requiring Building Information Modeling (BIM) on projects. Some clients have very detailed standards and expectations for the BIM process, and some clients say that they want BIM but have not idea what they really desire or how to get BIM. And then, there are clients that fall somewhere between those two types. Many clients (especially in the private sector) that have BIM standards in place have not publicized their standards, but will provide it to the design/construction team for specific projects. However, there are public entitites that have established BIM standards and have posted those standards on the internet and are accessible to anyone with internet access. Since it is nice to reference those BIM standards, I thought that I would list various public entities which have BIM standards that you can reference.
As an Architect, I find it helpful to be able to look at a floor plan and see the occupancy load for each room, and some building permit reviewers require this information be shown on the plan. My previous blog article addressed creating a schedule in Revit to show occupancy loads for rooms. This article will take off from that point and desmonstrate how to create a room tag to place on a floor plan view that shows the occupancy load of the room.
Working with building codes is an important aspect of working as an Architect during the design stages of a project, and knowing the occupancy of each room is a key component to that. This article will demonstrate how to create a Revit schedule that shows the occupancy load for each room in your BIM file. It will use a key schedule as the source of information for calculating loads, so this article will address creating that key schedule as well.
External References (xrefs) are an important part of working with AutoCAD and its vertical packages. I consider xrefs a critical and key feature of AutoCAD in the AEC industry and encourage you to look into them if you are not currently utilizing them on your projects. There are many aspects of good utilization of xrefs, but I thought I would list a few tips in this article.
Windows have been being placed at corner intersections of building walls for a long time, but they have not necessarily been an easy thing to show with design software. AutoCAD Architecture users have found workaround solutions for them since the inception of the software, but that no longer needs to be the case with the 2013 release. AutoCAD Architecture 2013 now has a new command tool specifically for placing Corner Windows.
Before an Autodesk Revit family is put into production, it should be cleaned up to reduce size and eliminate overhead that does not need to end up in a project file. Information that is not required by the family should not be kept in the family. The final step in family creation before putting a family into production should be the cleanup effort.
It is becoming more common for the Level of Development (LOD) to be specified on projects that require Building Information Modeling (BIM). Many times, the “LOD” term is thrown around and utilized without the specifier being familiar with what the term really means. As a result, confusion abounds and clients may say they want “a LOD 500 project”, although it does not really exist.
My previous article discussed the importance of creating Clearance Zones inside Revit familes for equipment and items that need clearances for ADA, safety, air movement, or other reasons. While that article also discussed the behind the scenes set up to get Clearance Zones into a Revit family, this article finishes the process of creating the actual Clearance Zone.
Many pieces of equipment in a building have clearance zones that are required around the equipment for a variety of reasons. It may be a drinking fountain that requires ADA clearance, an electrical panel that requires code clearance in front it, or mechanical equipment that requires air movement or access clearance around it. For whatever the reason, it is good to build that clearance zone into the Revit family so that it be used for interference detection through Revit or Navisworks.
When using Autodesk Revit Architecture, users typically place Rooms in the model and give each Room a name. By default, the Room will receive the name of “Room”, unless the user selects a predefined name for that Room or changes the name. When a project contains hundreds (or thousands) of defined Rooms, it is easy to lose track of Rooms that may not have been renamed to something other than the default “Room” name. This article will show you how to create a filter that accentuates any Rooms that have the name of “Room”.
In February 2011, I reviewed a new free product on the market for 3D model review named Tekla BIMsight by Tekla, Inc. (Read review) Tekla has recently released the new Tekla BIMsight version 1.3, and the big point is that it is still a free product.
As I mentioned in my first article on the BIMsight software, this is a basic clash detection software that allows you to bring several different 3-D models together for project collaboration and collision detection. While it is not a robust software, it performs clash detection that can meet the needs of many people and that I believe warrants consideration. It is a straight forward software that is not difficult in learning to use and also has a decent forum support system that is easily accessible from within BIMsight.
Revit Architecture 2012 has many family templates installed with the software during a standard installation and includes most of the family templates that are also installed with Revit MEP. (A previous blog post lists each of the family templates installed with the various Revit packages.) Revit Architecture also allows the user to place Revit MEP connectors in families, and that capability is the reason for this post since it has restrictions.
