Dead Loads

The Dead Load module provides an assembly-based approach to calculating building component weights. Build assemblies by selecting materials from an extensive library for accurate, documented, and repeatable dead load calculations.

Dead Load Summary View

Key Features

  • Assembly-based organization for building components (roofs, walls, floors)
  • Extensive material library with 200+ pre-defined items organized by category
  • Custom material creation for project-specific components
  • Bulk import from CSV, TSV, or Excel spreadsheets
  • Automatic weight summation in pounds per square foot (psf)
  • Organization-wide material library sharing
  • Professional PDF export with project branding

Getting Started

  1. Navigate to your structure in the left sidebar
  2. Click the three-dot menu and select Add Module
  3. Choose Dead Load from the module list
  4. Click Add Assembly to create your first assembly
  5. Search or browse the material library to add components
  6. Name your assembly and click Save Assembly

Assembly Management

Assemblies represent distinct building components (e.g., "Typical Roof Load", "Exterior Walls"). Each assembly contains multiple materials with individual weights that sum to a total weight in pounds per square foot (psf).

Adding Assemblies

  1. Click Add Assembly on the main Dead Load page
  2. The Assembly Editor opens with access to the material library
  3. Search or browse for materials to add
  4. Name your assembly descriptively (e.g., "Typical Roof Load")
  5. Click Save Assembly

Editing Assemblies

Click Edit Assembly next to any assembly in the summary view to open the Assembly Editor.

Assembly Editor

In the editor you can:

  • Add materials from the library by clicking on them
  • Remove materials using the trash icon
  • Reorder materials by dragging the handle icon
  • Rename the assembly using the name field
  • Delete the entire assembly using the Delete button

Assembly Editor Features

Element Description
Assembly Name Editable text field for identification
Material List Shows all materials with names and weights
Drag Handles Reorder materials by dragging
Remove Buttons Delete individual materials
Total Weight Automatically calculated sum in psf

Deleting Assemblies

  1. Click Edit Assembly to open the Assembly Editor
  2. Click the Delete button at the bottom of the editor
  3. Confirm the deletion when prompted

Permanent Action

Deleting an assembly removes it and all its materials from your project. This action cannot be undone.

Material Library

The module includes an extensive library of construction materials organized by category.

Material Categories

  • Acoustical fiberboard
  • Gypsum board (various thicknesses)
  • Plaster types
  • Suspended systems
  • Clay brick wythes (4", 8", 12", 16")
  • Concrete masonry (4" - 12")
  • Light, normal, and heavy weight options
  • Various grout configurations
  • Metal decking (various gauges)
  • Wood decking
  • Insulation types
  • Roofing materials
  • Waterproofing membranes
  • Floor fill materials
  • Tile and terrazzo
  • Hardwood flooring
  • Subflooring options
  • Wood framing (2x4 through 4x16)
  • Various spacings (12", 16", 19.2", 24" o.c.)
  • Frame partitions and walls

Searching Materials

Use the search box for instant filtering as you type. For example, typing "deck" shows only materials containing that term.

Filtering by Type

Use the dropdown menu to filter materials:

  • All Materials: Default and custom materials
  • Default Materials: Pre-built library only
  • Custom Materials: User-created materials only

Adding Materials

Create custom materials for project-specific components not in the default library.

New Material Dialog

  1. Click + New Material in the material library panel
  2. Category: Search existing categories or create a new one
  3. Material Name: Enter a descriptive name
  4. Weight: Enter weight in psf (minimum 0.01)
  5. Make available for new projects: Check to add to your organization's default library
  6. Click Create

Organization Library

Materials marked "available for new projects" become part of your organization's default material library for all future projects.

Editing Materials

Custom materials can be modified after creation:

  1. Locate the custom material in the library (filter by "Custom Materials")
  2. Click the edit icon next to the material
  3. Modify the category, name, or weight as needed
  4. Click Save to apply changes

Default Materials

Pre-built library materials cannot be edited. Create a custom material with your preferred values instead.

Deleting Materials

Remove custom materials that are no longer needed:

  1. Locate the custom material in the library
  2. Click the delete icon next to the material
  3. Confirm the deletion when prompted

Materials in Use

Materials currently used in assemblies cannot be deleted. Remove them from all assemblies first.

Bulk Import

Import multiple materials at once from spreadsheet data.

Import Process

  1. Click Import Materials

    Import Dialog

  2. Choose your import method:

    • Upload file: CSV, TSV, or Excel files
    • Paste data: Copy directly from spreadsheet
  3. Paste or upload your data

    Import Paste Data

  4. Configure parse options and preview

Best Practices

See Also

For a complete load analysis workflow, see the Common Workflows guide which covers coordinating dead loads with other load types.

Assembly Organization

  • Create separate assemblies for distinct building components
  • Use clear, descriptive names
  • Group similar materials together
  • Order materials as they appear in construction (top to bottom)

Material Selection

  • Verify weights match project specifications
  • Use search to quickly find materials
  • Create custom materials for specialty components
  • Include mechanical allowances where applicable

Partition Loads

Per ASCE 7-16 Section 4.3.2, use a minimum partition load of 15 psf where actual partition layouts are unknown or subject to change.

Quality Control

  • Review cumulative weights for reasonableness
  • Compare to typical values for similar assemblies
  • Document assumptions in assembly names
  • Export PDFs for record keeping

Code Reference

Dead load requirements per ASCE 7-16 and IBC:

  • ASCE 7-16 Section 3.1: Dead loads shall be based on actual weights of materials and construction
  • ASCE 7-16 Section 4.3.2: Minimum partition load of 15 psf where actual weight is unknown
  • IBC Section 1606: Equipment loads shall include weight of equipment, supports, and attached systems
  • ASCE 7-16 Section 2.3.1: Load factors: 1.2D (load increase) or 0.9D (load decrease)

The assembly-based approach ensures compliance by using actual material weights from industry-standard sources.
