Underpinning and support of excavation access require legal strategy that respects the engineering risk.
Why underpinning and SOE access are different
Underpinning, tie-backs, anchors, sheeting, shoring, bracing, and support of excavation can affect the adjoining structure itself. The requested access should therefore be supported by specific engineering proof, code analysis, monitoring, insurance, and clear limits on the work.
The current RPAPL 881 statute expressly includes certain foundation and building supports where required by code, regulation, or local law. That does not make every request reasonable. The details remain critical.
Engineering proof and monitoring
Engineering submissions should explain the construction method, the affected building elements, anticipated movement, monitoring devices, trigger levels, response protocol, emergency procedures, and closeout requirements. A court or adjoining owner needs to understand why the proposed approach is safe and necessary.
Monitoring provisions should coordinate with a broader construction monitoring agreement, including baseline survey, vibration limits, crack gauges, optical monitoring, reporting, notice, and stop-work triggers.
Risk allocation
Insurance, indemnity, property damage claims, professional review fees, license fees, and repair obligations should be addressed before access begins. For high-risk excavation, poor drafting can turn an access dispute into property damage litigation.
Our firm also handles excavation and underpinning litigation and adjacent construction damage claims, so access terms are drafted with the possibility of future litigation in mind.
Common questions
Can underpinning be included in an RPAPL 881 license?
The current statute includes certain foundation and building supports, including underpinning where required by code, regulation, or local law. The request still must be technically supported and properly conditioned.
What should an adjoining owner request before allowing underpinning access?
At minimum, relevant drawings, engineering reports, monitoring plan, insurance materials, schedule, contractor information, emergency protocol, and proposed license terms should be reviewed.
Why is support of excavation legally sensitive?
Because SOE work can affect structural stability, neighboring property, tenants, insurance, and future damage claims. Legal and engineering review should proceed together.
