(a) If any portion of the excavation will be within five feet of any portion of a structure on the property of another, the owner of the property to be excavated or the person performing the excavation work shall reinforce or brace the neighboring structure in order to prevent sagging, settling, cracking or collapse of its foundation and walls. The owner of the property to be excavated shall be responsible for the cost of the reinforcement or bracing. The reinforcement or bracing shall be done in a manner consistent with the provisions of the building code and prescribed by the building commissioner in rules. The building commissioner shall give consideration to the nature of surrounding soil, the depth of excavation, the size of the affected structure and other factors that may be relevant to the appropriate reinforcement or bracing.
(b) If any portion of the excavation will be within five feet of any portion of the public way, the owner of the property to be excavated or the person performing the excavation work shall reinforce or brace that portion of the public way in order to prevent sagging, settling, cracking or collapse.

No person shall begin or conduct any excavation within five feet of the public way, or within five feet of any portion of a structure located on the property of another, without maintaining in effect a commercial general liability insurance policy against all claims for damage, death and injury arising from the excavation. The policy shall be in an amount determined by the building commissioner, based on the size of the excavation and the proximity, construction and occupancy of structures on adjacent property. In no event shall the amount be less than $1,000,000.00 per occurrence for bodily injury, personal injury and property damage and the policy shall provide for 30 days' advance notice to the City of Chicago prior to cancellation or lapse of the policy. Proof of the required insurance shall be submitted as part of the application for the permit for the excavation and shall remain in full force and effect throughout the duration of the permit period.
