Planning a Commercial Window Replacement in an Occupied Building
Phasing, tenant communication, and logistics decisions that determine whether a commercial re-glaze succeeds.
Define the phasing before you bid
Phasing drives cost more than almost any other variable in commercial glazing. Whether crews work floor by floor, elevation by elevation, or after hours changes crew size, equipment rental, and total duration.
Establishing the phasing plan before bidding produces comparable proposals and prevents change orders once mobilization begins.
Access and equipment logistics
Swing stages, boom lifts, and crane picks each carry different permitting, parking, and scheduling requirements. On tight urban sites, staging space is often the constraint that dictates the schedule.
Walk the site with your glazing contractor early. Identifying lay-down areas, elevator access, and after-hours building access avoids costly surprises.
Tenant communication
Tenants tolerate disruption when they know exactly what to expect. A written schedule with dates, work hours, and contact information reduces complaints more effectively than any other measure.
We recommend a notice at project kickoff, a two-week look-ahead, and a 48-hour reminder before work reaches each suite.
Submittals and approvals
Product approvals, shop drawings, and structural calculations must clear the building department before fabrication. Lead times on custom commercial systems commonly run eight to sixteen weeks after approval.
Building the approval timeline into the project schedule prevents the most common source of commercial glazing delays.
