Foundation Geometry
The Foundation Geometry Plan indicates the extents and heights of concrete components. The purpose isn’t to duplicate the architects or engineers information, just supplement it with model data. It’s a great tool for steep lots with stepped foundations. Often the concrete contractor has to step the foundation stem walls to the grade and the finished steps aren’t exactly known until the foundation is built. The contractor simply marks-up the plan indicating the step locations and heights. This information can then be entered into the model and any adjustments to steel columns or framing can be made.
Foundation Embedment
The Foundation Embedment Plan indicates the location of anchor bolts, hold down stabs, target plates, custom or manufactured column bases and any other foundation embedments. Because embedments are modeled last, after windows, doors, steel, layout, and point loads are all resolved, the embedments are located correctly. Anchor bolts are centered in stud/joist bays, SSTB’s are aligned with the hold downs and steel anchor bolts align with base plates. Notation makes layout in the field quick and easy with red dimensions indicating typical anchor bolts and blue indicating custom embedment locations.
Floor Framing Plan
Similar to a plan you might get from iLevel or other engineered lumber provider but done by someone who cares about your whole building and knows how the floor system integrates with any of the other timber, steel, or concrete components. Bill of Materials (BOM) indicates ID, Quantity, Length, Material, and grade of all the pieces.
Sections
2D Sections of the building are the first step to 3D modeling. By carefully drawing accurate sections we can identify the geometric points that define the building.
Wall Key Plan
The Wall Key Plan is pretty simple, just a key so that the field crew can easily find the wall they need to build in the shop drawings. Multi-level buildings get a Wall Key Plan for each level.
Wall Framing Shop Drawings
Individual wall framing drawings with pretty much everything figured out. Gridlines and elevation callouts for reference. Window & door RO’s, header, trimmer and king conditions, point loads, outlookers & beam pockets, 3x or 4x panel edge studs where required, hangers & hold downs, top & bottom plate conditions, layout for proper joist/stud/rafter stacking, Bill of Materials including Label, Quantity, Length, Angle & Bevel cuts, material & grade as well as shear transfer information from the engineer for each wall.
Steel Key Plan
The Steel Fabrication Key Plan is another key plan identifying the different custom steel components for fabrication. The 3D view is helpful for understanding the steel piece in context.
Steel Shop Drawings
Steel Shop Drawings for fabrication. Beams, columns, moment frames, and custom connectors. Since the steel was all modeled in the same environment with the light framing, foundation, timber, and other steel components we’ve got a lot of confidence that all the holes, buckets, and tabs all line up and work properly. We save money on fabrication by doing the design ourselves rather than relying on the fabricator and we can more easily send the steel fabrication out for competitive bids rather than relying on one subcontractor for the drawings.
