With continuous economic development, diverse building structures have become integral to modern life. Site-specific adoption of prefabricated systems—such as concrete, steel, and modern timber structures—has gained momentum. Prefabricated steel structures are widely used in industrial, commercial, agricultural, and other sectors due to their rapid installation and contribution to efficient project completion. Below are key preparations for steel structure installation in prefabricated industrial buildings, which align with standard steel construction practices:

1. Foundation and Anchor Bolt Preparation

• Anchor bolt positioning: Ensure precise placement and protection of anchor bolts during foundation construction.

• Elevation control: Verify the top elevation of foundations and anchor bolts against design specifications.

• Post-construction inspection:

• Check alignment of grid axes.

• Confirm span dimensions comply with design requirements.

• Validate foundation top elevation accuracy.

• Inspect anchor bolt positions and elevations per design and code standards.

2. Component Pre-Installation Checks

• Dimensional inspection: Before hoisting, inspect components (e.g., beams, columns) for geometric accuracy as per the Code for Construction and Acceptance of Steel Structure Works. Deviations must not exceed code limits.

• Marking and labeling:

• Number components according to design drawings.

• Mark installation centers, elevation points, and lifting lashing points on steel columns.

• Measure column lengths; record errors and note adjustments (e.g., using grease pencil markings) for correction during grouting.

3. On-Site Component Management

• Documentation: Ensure components arrive with quality certificates and detailed inspection records.

• Storage protocols:

• Organize components by type, model, and installation sequence in designated areas.

• Use adequately sized timber supports under stacked components to prevent settling.

• Align support points vertically for same-model stacked components.

• Inspect for deformation; rectify issues before installation.

4. Compliance and Quality Assurance

Adherence to construction codes and rigorous preparation ensures smooth installation of prefabricated steel structures. Proper foundation work and component management lay the groundwork for efficient assembly, directly impacting the building’s functionality and longevity.

By prioritizing these preparatory steps, contractors create optimal conditions for successful structural installation, ensuring prefabricated industrial buildings meet design, safety, and performance standards.
