Scenario

A structural engineer's report, commissioned after staff noticed water damage in the basement of a renovated community services facility, confirmed what everyone feared: the foundation work was defective and the building's structural integrity had been compromised. The non-profit agency that operated the facility had completed the renovation approximately 4 years earlier, transforming an aging property into a modern program space where vulnerable populations received essential services. The project had been celebrated at the time, with volunteer board members, staff, and community partners gathering for a ribbon-cutting ceremony that marked what was supposed to be the beginning of decades of reliable service delivery.

The renovation had involved a general contractor selected through a competitive bidding process overseen by the agency's board. The general contractor had in turn subcontracted the foundation work—including waterproofing and drainage installation—to a specialty foundation contractor. At the time, the subcontractor had assured everyone that the waterproof membrane was properly installed and had signed off on the drainage specifications. The work had passed inspection, invoices had been paid, and the project had closed out without apparent incident.

The problems emerged gradually over the following years. What initially appeared to be minor settling in the foundation revealed itself as something far more serious. Water began seeping through the basement walls after heavy rains, pooling in storage areas where the agency kept supplies for its programs. Cracks spread along the foundation walls. Water stains bloomed across ceiling tiles in the program space. The structural engineer's report, completed approximately 6 months after staff first documented the water damage, traced the infiltration to improper foundation waterproofing and inadequate drainage installation—work that had been performed by the subcontractor during the original project.

When the agency's executive director contacted the general contractor to discuss the deficiencies, the response came not from the contractor directly but from the contractor's lawyer. The letter pointed the finger squarely at the subcontractor, asserting that the subcontractor had handled all foundation work and bore responsibility for any failures. The agency now faced a decision about whether to commence litigation, and the general contractor faced a parallel decision about whether to bring the subcontractor into any resulting legal action. The damages at issue included hundreds of thousands of dollars in remediation costs, disruption to programming for vulnerable populations, and the prospect of extensive structural repairs to a building that was supposed to serve the community for decades.
