1.1 Scope of prEN 1991-1-6

(1) prEN 1991-1-6 provides guidance and general rules on the determination of actions relevant for the design of buildings and civil engineering works, including geotechnical structures, for their execution stage.

NOTE Actions for design during execution include those that only arise from execution activities and act during execution, termed construction actions (for example personnel and hand tools, auxiliary structures, equipment and elements used during execution), and others that are present during the service life of the completed structure (for example self-weight, wind, etc.) but which can act differently and/or have different values during execution.

(2) prEN 1991-1-6 provides guidance and general rules for the determination of actions for the design of auxiliary structures, elements and equipment used during execution in case they are designed to the Eurocodes and not to other European Standards.

NOTE Other European Standards (e.g. EN 12810, EN 12811, EN 12812) provide specific rules for certain types of auxiliary structures, equipment and elements used during execution.

(3) prEN 1991-1-6 gives rules for buildings and bridges during execution to supplement the provisions in EN 1990.

NOTE For combination rules for execution, see EN 1990.

1.2 Assumptions

(1) The general assumptions given in EN 1990 apply.

(2) The application of this document follows the limit state principle and is based on the partial factor method, unless explicitly prescribed differently.

(3) The verification of buildings and civil engineering structures in transient design situations is undertaken in accordance with the Eurocodes, accounting for the interaction with any auxiliary structures, elements and/or equipment.

(4) When using European product standards covering auxiliary structures, equipment and elements used during execution, it is assumed that the design basis, design requirements and, if provided, the safety and operational design limits specified in these product standards are taken into account.

(5) Adequate planning, documentation, communication, control and supervision are provided during execution, involving all relevant parties.

NOTE Execution of a structure can involve interaction between several parties from diverse engineering fields, responsible for the design, fabrication, transportation and execution of different subsystems used during the execution of a structure.
