CPV Code 451 – Site Preparation
What does CPV code 451 cover?
CPV code 451 (Site preparation) covers all services that must be performed before actual construction begins. This includes site setup and securing, earthworks such as excavation, grading and terrain modelling, as well as preparatory measures like clearing, tree felling and disposal of contaminated soil. Ordnance clearance and soil investigations also fall under this code.
These services are essential for any construction project start. Without proper site preparation, no building construction, infrastructure project or civil engineering work can begin. CPV code 451 thus forms the foundation of the entire construction procurement chain.
Who uses this CPV code?
Public contracting authorities such as municipalities, state authorities and federal institutions regularly tender site preparation works. Particularly common areas include municipal construction projects for residential and commercial developments, infrastructure projects requiring extensive earthworks, remediation and demolition projects, and military property clearance.
Typical bidders are civil engineering companies, demolition firms, earthworks contractors and specialised ordnance clearance services.
How does Patterno help?
With Patterno HIT, companies in the site preparation sector find relevant tenders daily across all 1.000+ German procurement portals. Instead of manually searching DTVP, Vergabe24, Staatsanzeiger and dozens of other platforms, Patterno delivers qualified matches straight to the inbox.
Patterno BID for construction goes further: the AI-powered calculation agent supports the processing of bills of quantities. Especially for earthworks with hundreds of individual items (different soil classes, transport distances, compaction levels), automated calculation saves considerable time.
Typical tender volumes
Site preparation typically accounts for 5–15% of total construction volume. For a building project worth EUR 10 million, site preparation can amount to EUR 500,000–1,500,000. For major infrastructure projects, volumes are often significantly higher.
