Earthworks - Part 3: Construction procedures

This European Standard provides execution procedures for excavating, transporting and placing soils and rocks for the construction of earth-structures and guidance for the work. Additionally, it includes excavation and placement of rock materials underwater.
Dredging of soils and the associated hydraulic placement of fills are covered by EN 16907-6 and EN 16907-7.
Execution of earthworks follows the conclusions of the earthworks design and optimization phase (EN 16907-1), which should anticipate soil and rock specificities and their suitability. In case some events could not be foreseen, additional design is performed during the execution of works.

Erdarbeiten - Teil 3: Ausführung von Erdarbeiten

Diese Europäische Norm stellt Verfahren für den Aushub, Transport und Einbau von Böden und Fels für die Ausführung von Erdbauwerken und einen Leitfaden für die Erdarbeiten bereit. Sie behandelt außerdem den Aushub und Einbau von Felsmaterialien unter Wasser.
Das Nassbaggern von Böden und die damit verbundenen Auffüllungen im Spülverfahren sind durch FprEN 16907 6 und prEN 16907 7 abgedeckt.
Die Ausführung von Erdarbeiten richtet sich nach den Ergebnissen der Bemessungs- und Optimierungsphase der Erdarbeiten (prEN 16907 1), mit denen die Besonderheiten von Boden und Fels und ihre Eignung vorhergesehen werden sollten. Beim Eintreten von nicht vorhersehbaren Ereignissen werden zusätzliche Bemessungsschritte während der Ausführung der Erdarbeiten durchgeführt.

Zemeljska dela - 3. del: Postopki izvajanja zemeljskih del

Ta standard opisuje postopke izvajanja izkopavanja, transporta ter vgradnje zemljin in kamnin za konstrukcijo zemeljskih struktur. Zajema izkopavanje in vgradnjo kamnitih materialov pod vodo. Izkopavanje zemljin in povezana hidravlična namestitev nasipov sta zajeti v 6. delu tega standarda. OPOMBA: Izvajanje zemeljskih del sledi sklepom faze projektiranja in optimizacije zemeljskih del (1. del), ki mora predvideti posebnosti zemljin in kamnin ter njihovo primernost. V primeru nekaterih dogodkov, ki jih ni bilo mogoče predvideti, se dodatno projektiranje izvede med izvajanjem del.

Overview

EN 16907-3:2018 - Earthworks. Part 3: Construction procedures (CEN) provides practical execution procedures for excavating, transporting and placing soils and rocks in the construction of earth-structures. The standard covers on‑shore and underwater rock excavation and placement, and sets out requirements that follow the earthworks design and optimisation phase (EN 16907-1). Dredging of soils and hydraulic placement of fills are addressed separately in EN 16907-6 and EN 16907-7.

Key topics and technical requirements

The standard guides contractors and engineers through the full execution cycle of earthworks with emphasis on practical control and safety. Major topics include:

• Prerequisites and design interface
  • Execution must follow conclusions from the design/optimisation phase (EN 16907-1); unforeseen events require additional design during execution.
• Climatic and environmental considerations
  • Site-specific seasonal limitations, dust control, noise, contamination handling and protection of watercourses.
• Excavation
  • Material‑based excavation techniques, rock excavation considerations (including underwater blasting precautions), protection of cuts, stability and drainage measures.
• Underwater works
  • Equipment selection, tolerance and monitoring requirements, and environmental protection when excavating or placing rock underwater.
• Transportation
  • Bulk transport methods, haul road design and trafficability, lorry transport, alternative transport (water, rail) and protection of existing structures and buried utilities.
• Filling and compaction
  • Material grouping, compaction specifications, layer thickness and spreading, compaction equipment selection, risks such as over‑compaction and generation of pore pressures.
• Quality measures
  • Trial sections, supervision, monitoring and verification during execution (informative annexes provide example practices and equipment types).

Applications and who uses it

EN 16907-3 is targeted to professionals involved in earthworks construction and quality control:

• Civil and geotechnical engineers
• Earthworks contractors and site managers
• Project engineers and construction supervisors
• Environmental managers and public works authorities
• Consultants preparing specifications, execution plans and tender documents

Practical applications include road and railway embankments, earth dams, foundations and coastal or marine rock placements where underwater execution is required.

SIST EN 16907-3:2019

Note 1 to entry: The minimum and maximum void ratios correspond to the densest state (ID = 100 %) and loosest state (ID = 0 %) respectively (=[emax – e/ emax - emin] × 100 %). 3.6 fine soil soil with at least 15 % fines content, depending on national practices 3.7 fine active soil water-sensitive fine soil which exhibits specific shrinking/swelling properties to be taken into consideration for earthworks 4 General considerations 4.1 Prerequisites to execution of earthworks Before the beginning of construction, all geotechnical design issues should be solved, including temporary and permanent stability, erosion and settlements. All unresolved issues during design shall be identified to all parties and highlighted before the commencement of construction. In this case, the responsibility for closing out shall be made clear. Before the commencement of each part of works, the design of each part of the earthworks shall have been completed, including the assessment of the available materials and their suitability (see EN 16907-1 and EN 16907-2). 4.2 Climatic conditions Before commencing earthworks, the prevailing climatic conditions at the construction site shall be considered. Seasonal climatic variations can impose limiting factors on earthworks. During periods of rainfall, consideration should be given to suspending earthworks operations in wet sensitive materials. When necessary, the earth surfaces should be sealed to prevent the ingress of water. In dry climatic conditions, consideration should be given to preventing evaporative losses by covering the exposed earth surfaces with non-sensitive materials. NOTE Seasonal climatic considerations will vary depending on different regions. For example, a frozen ground surface may provide a temporary working platform that can enhance the excavation of soft soil. 4.3 Environmental factors All earthworks should comply with the relevant environmental legislation. Earthworks have the potential to harm the natural and built environment and therefore they should be planned in such a manner so as to minimize the potential for harm. The environmental factors to be considered during earthworks construction commonly include the following: Noise – European and national regulations should be considered. It is applying for receptors, e.g. domestic dwellings which are affected by the increase of noise beyond legal limits. Assessments should be made of the noise emissions of the various types of earthwork machinery and background noise level readings taken prior to commencement of the earthwork operations.
