DIN 4420-3 - Service and working scaffolds - Part 3: Selected types of scaffolding constructions and their basic versions [2] DIN 4420-4 - Working and protection scaffolds – Prefabricated scaffolds – Materials, components, dimensions, loadbearing capacity and safety requirements
To prepare the bid, first a cost estimate is prepared to determine the costs and then establish the price(s). This involves reviewing the project's plans and specifications to produce a take-off or quantity survey, which is a listing of all the materials and items of work required for a construction project by the construction documents ...

A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...
In civil engineering, specified loads are the best estimate of the actual loads a structure is expected to carry. These loads come in many different forms, such as people, equipment, vehicles, wind, rain, snow, earthquakes, the building materials themselves, etc. Specified loads also known as characteristic loads in many cases.
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
Shoring is commonly used when installing the foundation of a building. A shoring system such as piles and lagging or shotcrete will support the surrounding loads until the underground levels of the building are constructed.
