Pre-installation conference
Also: Pre-installation meeting, Preinstallation conference, Pre-con meeting
Quick definition: A meeting held before a trade starts a complex or critical installation, bringing together the contractor, the installer, the consultant and often the manufacturer to confirm requirements, conditions and inspections.
Explanation
Beginner explanation
Before a roofer, curtain-wall installer or equipment supplier starts work, everyone involved meets to check that the surfaces are ready, the right products are approved, and everyone knows how the work will be inspected.
Technical explanation
Pre-installation meetings are usually required by the project meetings section of the specifications (MasterFormat Section 01 31 19 or a trade section). A typical agenda covers existing conditions and preceding work, approved submittals and shop drawings, installation procedures, environmental and site conditions, inspection and testing, and special safety requirements. The contractor schedules the meeting, prepares the agenda and distributes minutes. Many manufacturers require a pre-installation conference as a condition of their warranty for systems such as roofing and waterproofing.
Practical example
Before installing a 20-year warranted roof membrane on a municipal arena, the contractor holds a pre-installation conference with the roofer, the manufacturer's representative and the consultant. They confirm deck dryness testing, fastener patterns and inspection hold points, and record the minutes for the warranty file.
Why it matters
Many costly failures — leaks, warranty refusals, rework — trace back to work starting on unready substrates or with unapproved products. A short meeting prevents them.
Common confusion
Shares the acronym PIC with Principal-in-charge. Also called a pre-installation meeting.
- Principal-in-charge (PIC) — Same acronym (PIC)
