Erection Drawings

Professional Erection Drawing Services

At Fabrication Shop Drawings, we provide highly detailed erection drawings that guide on-site crews through the safe, efficient, and accurate installation of structural steel components. These drawings are essential for construction teams, site supervisors, and crane operators to visualize the structural layout and follow a defined assembly sequence.

Our erection drawings go beyond basic layout plans — they are developed with a focus on real-world conditions, including safety, sequencing, and coordination with other trades to prevent costly delays and rework.

🏗️ What Our Erection Drawings Include:

🔄 1. Assembly Sequences

• Step-by-step installation order of steel members, organized for structural stability and site feasibility.

• Indication of load paths and bracing priorities to ensure safe temporary conditions during assembly.

• Sequencing of major components such as:

  • Columns

  • Beams

  • Braces

  • Trusses

  • Decking systems

🛠️ 2. Installation Guidelines

• Clear layout plans and elevation views showing member positions and orientations.

• Reference grids, part marks, and field weld/bolt identifiers.

• Alignment and leveling instructions to match shop drawings and engineering specifications.

• Crane lift points and suggested rigging arrangements, where applicable.

🦺 3. Safety Requirements

• Notations of critical safety zones, fall protection anchor points, and temporary supports or bracing.

• Adherence to OSHA and industry safety standards for structural erection.

• Identification of stability-sensitive operations or high-risk sequences.

• Recommendations for safe lifting angles, temporary fixings, and crew access points.

🔩 4. Field Connection Details

• Detailed views of bolted and welded field joints, including:

  • Bolt sizes, spacing, and tightening requirements

  • Field weld symbols and specifications

• Adjustments and tolerance notes to account for field variations

• Annotations for shim plates, base leveling, grout pads, and other site-fitted components
