Introduction

This six-weeks course is intended to include material that can be basis of design for bored piles. The presented subjects will be more towards practical methods used for design and the theoretical origins of those methods. Construction methods and tolerances will also be passed over. Mainly, ICE SPERW will be the basis for construction specifications. Comprehensive explanation of ACI codes and committees and some of EC provisions is presented.

The modules are devoted to both geotechnical and structural design of bored piles. The geotechnical part includes the estimation of the carrying capacity of the piles, the safety factors, the settlement at working loads, the lateral load analysis, the group effect and static load tests. While the structural part comprises of determination of required longitudinal reinforcement, shear reinforcement, crack width control and a rapid overview of factors that control the service lifetime of the piles.

Objectives

Subjects given in this course cannot be found in a single textbook. The aim of the course is to gather enough information about the design and construction of bored piles for engineers intending to challenge this field. Also, it is useful for civil/geotechnical engineering students that have finished a first course in soil mechanics or geotechnical engineering or postgraduate students who would like to continue research about bored piles and deep foundations. On the other hand, structural engineers that use piles in their designs shall be greatly benefited from the methods and information introduced.

Ahmed Mufty

Ass. Prof. Ahmed Mufty, Ph.D., MISSMGE completed his studies in the department of civil engineering in the university of Baghdad. He earned his B.Sc. in 1985. He continued his postgraduate study in geotechnical engineering and got his M.Sc. in 1990 and his Ph.D. in 1997. Dr. Mufty started his practical life with piles early after graduation. He started lecturing 1992 and became a faculty member in the department of civil engineering of the university of Baghdad for the period 1995-2004. After 2004, he moved to UAE and worked in pile design and construction till 2019 when he moved to Rocscience Inc. in Toronto joining the geotechnical software team as geomechanics specialist.

Dr. Mufty has more than 34 years of practical and theoretical experience in civil and geotechnical engineering and accomplished designs with full technical management for shoring of deep excavations and pile foundations for more than 100 iconic projects in Iraq, UAE, Qatar, KSA, Oman, India and Canada. He is also expert in many other fields of geotechnical engineering. He supervised 11 M.Sc. and Ph.D. Students and authored/co-authored more than 15 technical articles, one book in Arabic and 5 other public notes.

Within this virtual platform, students are in continuous contact with professor in a tailored way, solving questions together, and widening knowledge and acquiring new skills. Students can also interact with other students and professors through webinars and forums.

As evidence of knowledge gained throughout the course, a certificate will be issued from the Virtual platform. This certificate is based on the modern technology Blockchain, which increases security, prevents fraud, builds trust and ensures you’re ready for the future.

Bored piles are the most reliable and durable foundation for heavy buildings. Bored piles transfer the loads of the building to deep strong strata. Design of piles is a hot subject and jobs for pile designers are always available especially in developing areas around the world. It is one of the best careers a geotechnical engineer may work at.
