An Occupied-Building Matrix for Concrete, Water and Indoor-Air Questions
Facilities teams can receive several reports about one location and still have no clear owner for the next decision. Use a responsibility matrix to connect each question with the right record, reviewer and operational decision. The matrix is a coordination aid; it does not assign contractual duties or replace professional qualifications.
Separate questions by evidence type
Put concrete condition observations, water-event history and actual indoor-air results on separate lines. A concrete condition map does not measure radon. A laboratory result does not establish repair suitability. EPA’s remodeling guidance is a useful reminder that moisture and radon questions can precede decisions about covering basement surfaces.
Name the person who closes each item
Distinguish the person arranging access from the qualified party evaluating the concern and the manager deciding how operations proceed. Record the approval or response being sought, not an assumed clearance. Where leases or contracts allocate responsibilities, verify those documents rather than inferring duties from job titles.
Copyable worksheet
Use one row for each field. Mark unknown information clearly and retain the original records.
| Field | Your note |
|---|---|
| Issue and zone | ____________________ |
| Evidence owner | ____________________ |
| Appropriate technical reviewer | ____________________ |
| Operational decision owner | ____________________ |
| Response needed before the next phase | ____________________ |
Worked example
Illustrative example: the building manager supplies a water-event log, a radon professional addresses testing, and a concrete reviewer considers a floor repair. Closing the concrete item does not automatically close the air-quality or occupancy item.
