  • QR Code: “Scan for Layout and Drawings”
  • Provides instant access to complete 8-page engineering documentation via smartphone
  • Links to: Digital Engineering Drawings (same content as physical delivery packet)
  • Accessible without carrying paper drawings to jobsite

Truss Specifications:

  • TRUSS ID: SP1 14’6” Speci[al]
  • Quantity: 4 of 4 (this is the fourth of four SP1 special trusses)
  • MARK: H1
  • SH (Span Height): 11-03-08 (11 feet, 3-8/16 inches)
  • TL (Truss Length): 14-06-00 (14 feet, 6 inches)

Truss Type Details

This tag identifies an SP1 14’6” Special truss:

  • One of 4 special-configuration trusses in the shipment
  • Weight: 93.716 lbs (rounds to 94 lbs per loading ticket)
  • Mark designation “H1” corresponds to placement shown on layout drawing
  • Special configuration likely for specific structural or architectural requirements
  • Intermediate size between the common 6’ trusses and full 24’ attic trusses

QR Code Functionality

According to Marcus (contractor), each truss has a QR code that shows its exact specifications. This digital system provides:

  1. Instant Verification: Framers can scan tag to confirm correct truss placement
  2. Engineering Access: Direct link to structural drawings and load calculations
  3. Installation Guidance: Shows proper orientation and connection requirements
  4. Quality Control: Ensures each truss is installed in its engineered location
  5. Documentation: Provides inspector access to approved engineering plans

Construction Workflow Integration

The QR code system streamlines the framing process:

  • Crew scans tag before installation
  • Verifies truss type matches layout drawing position
  • Confirms orientation (left rake, right rake, center, etc.)
  • Accesses bracing requirements specific to that truss type
  • Documents installation with photo record of tag and placement

Tag Placement

Physical Tag Details:

  • Attached to truss with metal plate connector visible at top of tag
  • “PLATE HERE” marking indicates connector plate attachment point
  • Tag positioned for easy access during installation
  • Durable material for outdoor storage and handling
  • Clear printing resistant to weather and job site conditions

Cross-Reference to Documentation

This SP1 14’6” Special truss (Mark H1) is documented in:

  • Loading Ticket: Listed as “SP1 14’6” Special (11-03-08)” - 4 pieces, 94 lbs each
  • Engineering Packet: Specific design drawings showing structural calculations
  • Layout Drawing: Position marked with “H1” designation on placement schematic

From Loading Ticket (cross-verified):

Tag matches perfectly with loading ticket specifications.

Construction Impact

This QR code system provides significant benefits:

For the Framing Crew:

  • Eliminates guesswork in truss identification
  • Reduces installation errors
  • Speeds up placement verification
  • Provides on-site access to engineering details

For Quality Control:

  • Building inspector can verify each truss against engineered plans
  • Owner can document proper installation with photo evidence
  • Contractor can confirm correct materials delivered and installed

For Documentation:

  • Digital record of each truss specification
  • Accessible long-term for future reference
  • Links physical structure to engineering calculations
  • Supports warranty and liability documentation

Modern Construction Technology

This represents best practices in modern engineered construction:

  • Digital documentation integrated with physical materials
  • Instant access to technical specifications
  • Reduced paper waste (no need to print full plans for field crew)
  • Enhanced accuracy through technology-assisted verification
  • Improved safety through access to proper installation procedures
