The existing South End Library was deemed to be structurally unsound by the City of Greater Sudbury, as a result a new 10,000 sq. foot facility needed to be constructed.
EBS Geostructural worked with general contractor Capital Construction, geotechnical consultants Terraprobe and structural engineers Halsall to install 32 micropiles carrying a factored load of 1250kN.</p>

THE PROBLEM
The geotechnical investigation identified loose soils over steep sloping bedrock and the need for a piling system.
Steep varying bedrock elevations required the piling system to be embedded into the bedrock.</p>

THE SOLUTION
Micropiles were chosen as the preferred technology because they would be able to be embedded into the sloped rock where other types of piles may not be able to guarantee proper bearing/seating
The project consisted of a hybrid solution using conventional foundations where rock was exposed and micropiles in the remaining locations

Compression Load: 1250kN (281 kips)
Total Length of Micropile: 8 to 17 metres
Embedment Depth into Bedrock: 3 metres
Total Number of Micropiles: 32
