Three numbers that help with planning
Area per truckload. An average of 54 m² per truck is the result for a mix of walls, slabs and balconies. Expanded-clay concrete walls alone travel at 90–100 m² per truck, sandwich walls at 45–55 m²; the weights of each type are listed in the element weight article.
Scale of an apartment building. The 23 buildings in this category average 7,253 m² of precast and 742 elements per building, i.e. 9.8 m² per element. These figures translate directly into crane days and site entries.
Production time. The weeks in the table run from the first to the last element in the production plan, not from the order. Production runs in parallel with erection: the first deliveries leave before the last slab is cast, so production time is not the client's waiting time.
How much does a precast wall weigh? Element weights in kg/m²
Where the numbers come from
The source is the plant's production system (ERP): m² and element counts come from the production plans assigned to the object, truckloads from delivery notes, and production weeks from the first and last element dates in the plan. Figures are not rounded or averaged between sites; projects without complete data are not in the table.
Element counts include walls, slabs, balconies, stairs, beams and columns; auxiliary items such as reinforcement billed by the kilogram are excluded. Truckloads are tractor-trailer sets, usually 22–24 t of elements. The table refreshes together with the project database.
Questions about the scale of precast
Answers are calculated from the same table, so they change with it.
- How many m² of precast fit on one truckload?
- An average of 54 m² per truck across all element types in 42 projects. For walls alone it depends on weight: 15 cm expanded-clay concrete walls travel at 90–100 m², normal-weight concrete at 60–70 m², sandwich walls at 45–55 m². A truck usually carries 22–24 t.
- How many precast elements does an apartment building have?
- Across the 23 apartment buildings in the table, an average of 742 elements and 7,253 m² of precast per building. The spread is wide, from a few hundred elements in a small social-housing block to several thousand in an apartment complex, which is why each building has its own row.
- How long does precast production take for one building?
- For an apartment building typically 14 weeks (median) from the first to the last element in the production plan; a single-family house usually takes one to three weeks. Production starts once shop drawings are approved and runs in parallel with erection, so the first elements reach the site long before production ends.
- Where do these figures come from and how often are they updated?
- From the plant's production system: production plans assigned to the object give m² and element counts, delivery notes give truckloads, production dates give weeks. The data is transferred to the project descriptions by script and refreshed with them; projects without complete data do not enter the table.
