BS EN 1536:2010+A1:2015

What is BS EN 1536 - Principles for the execution of bored piles about ?

BS EN 1536 is a European standard that covers the execution of special geotechnical work, enabling safety, performance and efficient operations in geotechnical applications. 

BS EN 1536 establishes general principles for the execution of bored piles. 

BS EN 1536 applies to bored piles with: 

• Uniform cross-section (straight shaft) 
• Telescopically changing shaft dimensions
• Excavated base enlargements 
• Excavated shaft enlargements 

BS EN 1536 applies to: 

• Bored piles with a depth to width ratio ≥ 5 
• Piles with a shaft diameter 0.3 m ≤ D ≤ 3.0 m 
• Barrettes with the least dimension Wi ≥ 0.4 m, a ratio Li / Wi between its largest and its least dimensions ≤ 6 and a cross-sectional area A ≤ 15 m² 
• Piles with circular precast elements used as a structural member with the least dimension DP ≥ 0.3 m 
• Barrettes with rectangular precast elements used as a structural member with the least dimension WP ≥ 0.3 m 

BS EN 1536 provides details and specifications relating to bored pile with a circular cross-section, bored pile with non-circular cross-section, straight shaft piles and piles with shaft and base enlargement, secant pile wall, contiguous pile wall, and widely spaced pile wall. 

Note 1: BS EN 1536 covers piles or barrettes which are formed in the ground by excavation and are structural members used to transfer actions and/or limit deformations. 

Note 2: BS EN 1536 covers piles with circular cross-sections and barrettes with rectangular, T or L or any other similar cross-section concreted in a single operation. 

Note 3: In BS EN 1536, term pile is used for circular cross-section structure and the term barrette for other shapes. Both are bored piles. 

Who is BS EN 1536 - Principles for the execution of bored piles for ?

BS EN 1536 on Principles for the execution of bored piles applies to: 

• Manufacturers and suppliers of bored piles
• Dealers and importers of bored piles 
• Geotechnical engineers 
• Companies involved in geotechnical services 
• Geo consultants, surveyors, and contractors 

Why should you use BS EN 1536 - Principles for the execution of bored piles ?

A bored pile is a pile or barrette formed with or without a pile casing by excavating or boring a hole in the ground and filling it with plain or reinforced concrete. Assessing data from the field, figuring out how to keep foundations or slopes solid, designing foundations, and supervising work on a construction site are all part of geotechnical work. 

BS EN 1536 provides users guidance on materials and products, including constituents such as bentonite and polymers, support fluids like bentonite suspensions and polymer solutions, concrete, and grout, enabling users to comply with material and product requirements given in the European standards. 

BS EN 1536 provides users guidance on execution of special geotechnical work, including construction tolerances, excavation, reinforcement, concreting, trimming, and pile walls, enabling prevention of uncontrolled inflow of water and soil into the bore. 

The adoption of BS EN 1536 allows users to standardize the physical and dimensional aspects of bored piles, enabling the efficient execution of special geotechnical work and minimization of backfill and disruptions.
