CPV Code 4512 – Earthworks
What does CPV code 4512 cover?
CPV code 4512 (Earthworks) is one of the most fundamental codes in construction, covering all works related to loosening, moving, placing and compacting soil and rock. This includes excavation with associated shoring (sheet piling, soldier pile walls), transport of earth masses, backfilling with compaction to specified degrees, and large-scale terrain modelling.
Additional typical services include soil improvement measures, soil replacement for non-load-bearing ground, groundwater management during construction, and drainage works. Soil classification according to DIN 18300 directly impacts calculation methods and pricing.
Who uses this CPV code?
Earthworks are required in virtually every construction project and are among the most frequently tendered construction services in the public sector. Key areas include residential construction (excavations for apartment buildings and underground garages), road construction (embankments and cuttings), utility installation (trenches for supply and drainage lines), and commercial area development.
Bidders are predominantly earthworks companies, civil engineering firms and specialised ground engineering companies with heavy equipment fleets.
How does Patterno help?
Patterno HIT helps earthworks companies find relevant tenders daily across all procurement portals. The AI identifies not only explicit earthworks tenders but also earthworks lots within larger construction projects.
Patterno BID is particularly effective for earthworks calculation: automatic processing of bills of quantities with hundreds of individual items — different soil classes, varying transport distances, changing compaction requirements — significantly reduces calculation effort. The iTWO integration enables direct transfer to the company's calculation software.
Typical tender volumes
Earthworks account for 30–50% of total volume in civil engineering projects and 5–10% in building projects. Volumes range from small landscaping measures (EUR 50,000–200,000) to large infrastructure projects (several million EUR).
