Compare the financial, operational, and risk trade-offs of purchasing a flat-pack prefabricated steel building kit versus hiring an on-site supervisor or contracting turnkey erection.
When procuring a prefabricated steel building in Europe, developers can choose between four distinct delivery tiers: 1) Supply Only (Kit Delivery), 2) Supply + Engineering Supervision, 3) Complete Turnkey Erection, and 4) Engineering Dossier Only. Choosing "Supply Only" offers the lowest capital cost (€110–€180/m² for the superstructure) and is ideal for general contractors with local crane and rigging resources. Adding "Engineering Supervision" (€3,500–€7,500 total) mitigates on-site assembly risk by embedding a senior SerBuild structural engineer on your site. Complete Turnkey Erection (€340–€580/m² total) provides a single point of responsibility for foundations, crane lifting, envelope cladding, and final certification.
Selecting the optimal procurement tier depends on your company’s in-house construction expertise, local equipment access, and project risk appetite:
Below is an itemized cost comparison for a standard 1,500 m² industrial warehouse erected in Western/Central Europe (2026):
| Delivery Scope Tier | What Is Included | Cost Range (€/m²) | Typical Project Cost (1,500 m²) | Client Responsibility |
|---|---|---|---|---|
| 1. Supply Only (Kit) | Steel frame, purlins, panels, bolts & 3D manual delivered DAP | €115 – €155 / m² | €172,500 – €232,500 | Local crane hire, rigging labor, foundation |
| 2. Supply + Supervision | Complete kit + Senior structural engineer on site (10–14 days) | €125 – €170 / m² | €187,500 – €255,000 | Local laborers/crane guided by our engineer |
| 3. Complete Erection | Complete kit + Certified rigging crew + Mobile cranes + Scissor lifts | €175 – €245 / m² | €262,500 – €367,500 | Foundation slab only (SerBuild erects building) |
| 4. Full Turnkey Project | Foundations, concrete slab, building, MEP, doors & commissioning | €360 – €560 / m² | €540,000 – €840,000 | Site access & utilities connection only |
| Evaluation Factor | Supply Only | Supply + Supervision | Complete Erection | Full Turnkey |
|---|---|---|---|---|
| Capital Cost Index | Lowest (100% Base) | +5% to +8% | +25% to +35% | +120% to +180% |
| Assembly Risk | High (on Client) | Very Low (Supervised) | Zero (on SerBuild) | Zero (Single Contract) |
| Speed to Completion | Depends on local crew | Fast (10–15 days) | Fastest (8–12 days) | Complete (6–10 weeks) |
| Crane & Tool Sourcing | Client sources | Client sources (guided) | SerBuild provides | SerBuild provides |
| Best Suited For | Experienced Contractors | General Developers & SMEs | Foreign Investors / Non-builders | Turnkey Facility Operators |
Evaluate whether you have experienced steel erectors and local mobile crane hire contacts.
Choose between Supply Only, Supervised Assembly, or Complete Erection during RFQ.
Concrete contractor installs anchor cages using SerBuild’s steel positioning templates.
Elements offloaded in reverse erection sequence for immediate crane pick-up.
Primary portals lifted, braced, and Grade 8.8 bolts torqued with calibrated wrenches.
Insulated panels fitted with vapor barriers, followed by final engineering inspection.
Submit your building dimensions, clear spans, and site location coordinates. Our structural engineering department provides itemized cost estimates and Eurocode 3 static reports within 24–48 hours.
Detailed answers to technical, manufacturing, export, and on-site assembly questions.
You will need: a 30t–50t mobile all-terrain crane, 2 scissor lifts or boom lifts, calibrated torque wrenches, impact guns, rigging slings, and a 4-to-6 person assembly crew.
Our senior structural engineer verifies foundation anchor bolt coordinates, oversees primary frame crane lifting, inspects bolted connection torque, supervises thermal insulation detailing, and signs off on quality compliance.
With a standard 5-man crew and a 40t mobile crane, the primary steel frame is assembled in 4–6 working days. Secondary purlins and insulated sandwich panels take an additional 5–8 days, completing the shell in under 2 weeks.
Yes. Because SerBuild provides EN 1090-2 CE certification, Eurocode 3 calculations, and 3.1 material test certificates, local insurance providers (e.g. Assurance Décennale in France, Bauleistungsversicherung in Germany) issue full coverage.
Yes. SerBuild includes 100% of structural Grade 8.8/10.9 hot-dip galvanized bolts, EPDM self-drilling cladding screws, butyl sealing tapes, anchor bolts, and color-matched flashings with a 5% surplus buffer.
