A Case Study on Effect of Vibration from Pile Driving on Nearby Buildings-Paper

Paper

Pdf Summary

The study investigated whether pile-construction vibrations at the Vizhinjam International Seaport project could damage nearby homes. After residents reported cracks following test-pile work, an expert team monitored vibrations during steel-casing installation and boring. Accelerometers measured ground and building vibrations at locations within 500 m; researchers also inspected buildings and recorded noise.<br /><br />The area’s buildings were often old or poorly constructed, and more than 1,000 were documented within 500 m. The most notable cracks were in two homes about 90 m and 130 m from the pile. Some damage, particularly in the first home, may have predated the work or resulted from settlement on filled ground, so the study could not establish that piling caused it. During monitoring, peak vibration velocity remained below 1.5 mm/s—within cited limits for structural safety, though perceptible to people as far as 200 m. Residents reported sensations such as rattling windows and shaking furniture, but no new damage was observed during the monitored work. Daytime noise was within the applicable limit.<br /><br />The authors concluded that the buildings were safe to occupy and that the cracks could be repaired. They recommended documenting building conditions before piling, monitoring vibration during construction, repairing the two affected homes, and avoiding nighttime work. Moving the pile location 60–80 m toward the sea reduced residents’ perception of vibration and noise, and complaints ceased. Temporary barriers made from precast concrete blocks or available tetrapods were also suggested.
