Drawing Coordination with Manufacturing

Erection drawings are coordinated with fabrication drawings to ensure that member marks, connection references and assembly sequences are consistent across all project documentation.

Sequence

Typical Installation Sequence

The following represents a typical steel structure erection sequence. Actual installation methods, sequencing and safety requirements are determined by the project structural system, local contractor methodology and project engineer requirements.

Foundation & Anchor Bolt Verification

Verify anchor bolt positions, grid dimensions and foundation elevations before steel erection.

Column Erection

Install columns on verified foundations, plumb and temporarily stabilize.

Main Beam / Rafter Installation

Install main framing members, connecting to columns per approved drawings.

Temporary Stabilization

Apply temporary bracing and stabilization as required during erection.

Bracing Installation

Install permanent bracing systems to establish structural stability.

Secondary Steelwork

Install purlins, girts, secondary framing and accessory supports.

Roof / Wall System

Install roof and wall cladding systems per project specifications.

Final Bolt Tightening & Inspection

Complete final bolt tightening, dimensional checks and quality inspection.

Note: This is a general reference sequence. Actual installation methods, sequencing, temporary stabilization and safety requirements must be determined by the local contractor and project engineer based on the specific structural system and site conditions.

Foundation Interface

Foundation and Anchor Bolt Interface

Proper foundation preparation is critical for successful steel structure erection. ZhongSai provides the steel-to-foundation interface documentation, while foundation construction is normally handled by local contractors.

Anchor Bolt Location

Anchor bolt positions and grid dimensions provided in foundation interface drawings.

Base Plate Interface

Scope Note: Foundation and civil works are normally constructed by local contractors. ZhongSai provides interface documentation and technical guidance, but does not default to undertaking local foundation construction.

Bolted Connections

Bolted Connections for Site Assembly

Most site connections are designed as bolted connections to enable efficient assembly without on-site welding. Connection details, bolt schedules and assembly requirements are documented in the approved drawings.

Bolt Identification

Bolts packaged by connection group with identification referencing the bolt schedule.

Connection Plates

Connection plates and gusset plates pre-fabricated and identified per drawing.

Splice Connections

Bolted splice connections for long members segmented for shipping.

Tightening Requirements

Bolt grades, tightening methods and torque values specified per approved drawings and project standards.

Note: Specific bolt grades, torque values and tightening procedures are determined by the approved project drawings and applicable standards. Do not substitute bolt grades or modify connections without technical approval.

Common Questions

Common Site Questions

Answers to frequently encountered questions during steel structure site installation.

What if a component cannot be found on site?

Cross-reference the member mark with the packing list and erection drawings. Contact ZhongSai delivery team with the member mark and project reference for clarification.

How to read component identification marks?

Member marks correspond to the erection drawing legend. Each mark identifies the member type, location and connection references shown on the approved drawings.

How do packing lists relate to installation drawings?

The packing list maps each packaged item to its member mark, which is referenced on the erection drawings. This allows site teams to locate components by installation sequence.

What if a connection detail is unclear during erection?

Do not modify the connection. Reference the connection detail drawing and contact ZhongSai engineering team for clarification. Site changes to structural connections require technical approval.

How to report component damage found on site?

Document the damage with photos, member mark and packing reference. Contact ZhongSai delivery team immediately for assessment and guidance on repair or replacement.

What if site dimensions do not match the drawings?

Stop work on the affected area, document the discrepancy with measurements and photos, and contact ZhongSai engineering team. Do not force components or modify structural members without technical approval.

Can the installation sequence be changed on site?

Sequence changes may affect structural stability during erection. Consult the project engineer and ZhongSai technical team before altering the approved erection sequence.
