7) Geotechnical Instrumentation & Monitoring.

8) Liquefaction Analysis.

9) Design of Reinforced soil walls / Reinforced soil slopes (Highway/Railway/Airport Approaches).

10) Design of Gravity/Reinforced Gabion walls.

Mr. Himanshu Kotak has done M.Tech in Geotechnical Engineering from IIT Kanpur. He is a BE-Civil degree holder from MSU Baroda. He has gained his experience by working with verities of work profiles starting from Trainee Engineer, Engineer, Sr. Engineer, Manager, and Project Manager Etc in Indian as well in MNC Companies. He has work experience on both Indian as well as abroad projects. He has worked with companies like Maccaferri, Techfab, TES-Oman, CGR India, TCE etc.

During his work, he has used verities of Indian as well as International codes for geotechnical practice. Some of these codes are listed here. IS6403, IS8009, IS 1904, IS 1892, IS2720 (All Parts), IS 2131, IS15284, IS 2911 (All Parts), IS 7894, IRC75, IRC5, BS8006, BS8004, Eurocode-7, FHWA, NCMA, IRC-SP-102 etc.

He has vast experience on using geotechnical design softwares such as Geoslope Slope-W, Seep-W, MSEW, RESSA, Geo-5, Plaxis, Macstars, Gawacwin, SR Wall, Anchor Wall, Allan Block etc. He is also very good at developing and using Excel spreadsheets.
