The Problem
Ceiling damage on 14th floor. Initial contractor estimate: cut open the entire bathroom on 15th floor to find source.
Detection Method
GPR mapped in-slab plumbing on 15th floor. Thermal found temperature anomaly. Acoustic confirmed leak at a specific fitting.
Results
200mm x 200mm patch. Repair scope reduced from 'cut the whole bathroom' to a single small patch. Dollars saved: approximately $8,000 in unnecessary restoration.
