We have the experience with Building Information Modeling (BIM) using Autodesk’s Revit® software on a variety of project types. By using BIM, we can provide you with a working 3D model of the cold-formed steel framing using a base model you provide us — or we can create one from scratch. Our light gauge steel Revit and Navisworks capabilities include BIM Level of Development (LOD) 200, 300, 350, 400, and 500.
Most shop drawings are completed in under two weeks from proposal approval. Projects requiring BIM typically extend over longer periods as coordination between multiple trades occurs. Timelines will depend upon the LOD requested, project complexity, and other trades’ BIM managers.
BIM LOD Capabilities
We can provide you with a working 3-D model of the cold-formed steel framing using a base model you provide us or one we create from scratch.
BIM Level of Development (LOD) 200
- The model element is graphically represented within the model as a generic system, object, or assembly with approximate quantities, size, shape, location, and orientation.
- Non-graphic information may also be attached to the model element.
BIM Level of Development (LOD) 300
- The model element is graphically represented within the model as a specific system, object, or assembly in terms of quantity, size, shape, location, and orientation.
- Non-graphic information may also be attached to the model element.
BIM Level of Development (LOD) 350 (Most Common)
- The model element is graphically represented within the model as a specific system, object, or assembly in terms of quantity, size, shape, orientation, and interfaces with other building systems.
- Non-graphic information may also be attached to the model element.
BIM Level of Development (LOD) 400
- The model element is graphically represented within the model as a specific system, object, or assembly in terms of size, shape, location, quantity, and orientation with detailing, fabrication, assembly, and installation information.
- Non-graphic information may also be attached to the model element.
BIM Level of Development (LOD) 500
- Information is attached to elements of the model such as costs, schedule, or other relevant data.
Usually not. Most general practitioner type structural engineers stay away from specialty engineering (aluminum, cold-formed steel, glass, trusses, etc.
It depends on the size and scope of the project. For a single-story retail building, we can complete the project in under two days’ time. However, our backlog of work may delay our start and require a couple of weeks to be returned to you.
The capacity of a stud depends on many variables. The stud size, height, gauge, bracing condition, and lateral load (wind) will all have an effect on the stud capacity. A structural engineer should be consulted to determine a metal stud wall capacity.
A structural stud is meant for use to resist environmental loads (dead, live, wind, snow, or earthquake). They usually have wider flanges and thicker galvanizing.
CFS shop drawings are needed when required by the contract specification, usually under 05400 or 09200. They are also needed when the construction drawings do not adequately represent what is to be built to support the imposed loads.
The subcontractor providing the metal framing is typically responsible for providing CFS shop drawings and calculations for approval.
