CPV Code 4522, Structural Works
What does CPV code 4522 cover?
CPV code 4522 (Structural works) covers the creation of the load-bearing building frame, all structural construction services that form the static system of a structure. This includes masonry (sand-lime brick, aerated concrete, clay brick, clinker), reinforced concrete works (foundations, floor slabs, ceilings, walls, columns, beams), reinforcement works and formwork.
The code also covers precast construction (concrete precast elements such as stairs, balconies, wall panels), chimney construction and natural stone works on facades and load-bearing components. Structural works form the core of every building project and typically account for 25–40% of total construction costs.
Who uses this CPV code?
Structural works are tendered in every new build and major renovation. Key public sector project types include school construction, hospitals, administrative buildings, social housing and sports halls. Bidders are structural works companies, masonry and concrete firms, precast manufacturers and general contractors.
How does Patterno help?
Patterno HIT delivers qualified tenders daily to structural works companies, filtered by project size, region and building type. The AI also identifies structural lots within general contractor tenders.
Patterno BID unleashes its full power in structural works: the calculation agent automatically processes extensive bills of quantities with hundreds of items, concrete by grade and placement location, reinforcement by diameter and conditions, formwork by system type and difficulty. What manually takes days, Patterno BID completes in hours.
Quality and standards
Structural works are subject to strict quality requirements: concrete must comply with DIN EN 206, masonry with Eurocode 6. Monitoring is carried out by recognised testing bodies. Bidders must frequently demonstrate quality management systems and reference projects.
