Technical Spec Sheet for Industrialized Construction Elements

Before designing the assembly of a prefabricated element, several technical questions need to be settled: how it's identified and what it's made of, what manufacturing tolerances it allows, what crane is needed to move it and with which lifting points, how it interacts with the load-bearing structure and finishes, and what maintenance it will need over its service life. This sheet brings those answers together in a single document per element type.

The Excel file is organized into five blocks: element identification (name, type, manufacturer, catalog reference, project and date), technical description (composition, construction system, applicable regulation, CE marking, ETA/DIT reference), dimensional characteristics (length, width, thickness or depth, manufacturing tolerances, unit weight and weight per m² or m³), transport and handling (on-site storage conditions, lifting points, minimum required lifting equipment, minimum crane capacity and transport protection), and assembly and interfaces (summary sequence, joints and assembly tolerances, interface with the load-bearing structure and waterproofing, and mandatory inspection points). It closes with a maintenance block: planned operations, recommended frequency and estimated service life.

It's a specification sheet for the element type, not a receiving log for the units arriving on site: it doesn't include manufacturing batch, arrival date or receiving-inspection results, because that information belongs to a different document and a different point in the process.

The maintenance block is the one least consulted early in the project and the one most needed years later: the recommended frequency and estimated service life of a facade element aren't looked up during assembly, but when someone reviews the building much later. In Bloqbase this sheet stays inside the project alongside the budget and takeoffs, available to whoever needs to check it during assembly or in a review years later, without depending on someone having kept the original Excel file somewhere findable.

How to put it to work on a real project

The idea isn't to download another file and forget it in a folder. Use it with a specific case: a pending certificate, a coordination meeting, a cost overrun or a handover to the developer. Fill in the resource with real data from your project, validate the result with your own technical judgment, and keep it as an internal reference to repeat the process next time.
