Supply Only vs. Complete Installation: Which Delivery Package is Best for You?

Choosing the optimal delivery package for an international steel building project depends on your local labor capabilities, crane access, project complexity, and regulatory landscape. SerBuild provides five tiered delivery models: (1) Engineering Only, (2) Supply Only (Flat-Pack Export Kit), (3) Supply + On-Site Technical Supervision, (4) Complete Frame Installation, and (5) Turnkey Delivery. For international contractors with general construction experience, "Supply + Supervision" offers the highest return on investment by combining low offshore manufacturing costs with guaranteed structural assembly quality.

⚡ Quick Answer / Executive Summary

Choosing the optimal delivery package for an international steel building project depends on your local labor capabilities, crane access, project complexity, and regulatory landscape. SerBuild provides five tiered delivery models: (1) Engineering Only, (2) Supply Only (Flat-Pack Export Kit), (3) Supply + On-Site Technical Supervision, (4) Complete Frame Installation, and (5) Turnkey Delivery. For international contractors with general construction experience, "Supply + Supervision" offers the highest return on investment by combining low offshore manufacturing costs with guaranteed structural assembly quality.

Key Engineering & Cost Takeaways

  • Supply Only: Best for experienced local contractors with in-house steel erectors and mobile cranes
  • Supply + Supervision: The most popular international option; eliminates assembly errors while saving 20–30% vs full turnkey
  • Complete Installation: SerBuild manages the entire mechanical erection crew on site
  • Turnkey: Single-point contract from foundations to interior handover in eligible jurisdictions
  • Tooling Requirements: 100% pre-drilled bolted joints eliminate on-site welding for all packages

Frequently Asked Questions

Detailed answers to technical, manufacturing, export, and on-site assembly questions.

We supply the complete manufactured steel structure, fasteners, cladding, and 3D drawings, plus dispatch a senior SerBuild structural engineer to your jobsite to direct foundation anchor checks, rigging, bolt torquing, and quality sign-off.

Yes. Because all SerBuild steel components are 100% pre-drilled, pre-cut, and piece-marked with alphanumeric codes matching the 3D step-by-step assembly manual, experienced general carpenters and metalworkers can assemble the building without specialized welding skills.

Depending on building size, you will need an all-terrain mobile crane or telehandler for offloading and lifting columns/rafters, scissor lifts for erectors, torque wrenches (for Grade 8.8/10.9 bolts), and standard impact drivers.

The supervising engineer prevents common site errors such as improper anchor bolt tightening, reverse purlin lapping, or scratched anti-corrosion coatings, ensuring full structural warranty validity.

For private developers, "Supply + On-Site Supervision" typically delivers the greatest cost savings, reducing overall project labor costs by 25–35% compared to hiring a full local turnkey contractor.
