Glazing is one of the most schedule-sensitive trades on any large commercial build. A late storefront package or a rejected IGU shipment can cascade into concrete, finishing, and occupancy delays that cost far more than the glazing contract itself. This guide is written for general contractors and project managers in Metro Vancouver who need to pre-qualify, specify, and coordinate a commercial glazing subcontractor on a project where getting it wrong is not an option.

Insurance and WCB: Non-Negotiable Minimums

Before any glazing sub sets foot on a Metro Vancouver commercial site, you need certificates confirming the following:

Commercial General Liability: Minimum $5M per occurrence for any project above the residential scale. Strata corporations and institutional owners increasingly require $10M on larger builds. Verify the policy covers completed operations — not just active work.
WCB Clearance: A current clearance letter from WorkSafeBC, dated within 30 days of mobilization. Any glazier working under a GC without valid WCB coverage shifts the liability burden to you as the prime contractor.
Auto and Equipment: Confirm commercial vehicle coverage for any delivery or lift equipment brought on site. Scissor lifts, boom lifts, and glazing trolleys are high-value equipment that must be insured under the glazier's policy.

WaveGlass carries $5M commercial liability and provides WCB clearance letters on request. We've been pre-qualified on strata, institutional, and mixed-use projects across Metro Vancouver and can provide documentation packages within 24 hours of request.

Scheduling Windows and Lead Time Planning

Glazing has two scheduling bottlenecks that GCs frequently underestimate: fabrication lead time and site readiness windows.

Fabrication lead time for commercial glazing systems in BC currently runs 3–6 weeks for standard storefront aluminum and glass packages. Specialty glass — low-e coatings, laminated, ceramic frit, or larger-format IGUs — can push to 8–12 weeks depending on the fabricator's queue. If your glazing package isn't on order before structure is complete, you're already behind.

Site readiness is the other constraint. Glazing can't proceed until openings are dimensionally verified (not just roughed in), substrates are clean and plumb within tolerance, and any anchor channel or embed work is inspected and signed off. Build your schedule so glazing templates happen immediately after substrate approval — not a week later.

Schedule Coordination Tip

Include your glazing subcontractor in the pre-construction schedule review. A good glazing sub will flag lead time conflicts before they become critical-path problems. If a glazing company doesn't ask about your schedule during pre-qualification, that's a red flag.

Pre-Qualification Checklist for Metro Vancouver GCs

Use the following as your baseline pre-qualification checklist for any commercial glazing subcontractor:

Project history: Can they provide references on three comparable projects (similar scope, value, and complexity) completed in the last three years? Call those references — ask specifically about schedule compliance and deficiency resolution.
Fabrication relationships: Do they have an established relationship with a certified BC fabricator, or are they brokering glass from out-of-province at unknown lead times? Local fabrication relationships directly affect your schedule reliability.
Site safety program: Does the company have a documented site-specific safety plan they can provide? On institutional and ICI projects, this is typically required before mobilization.
Deficiency warranty: What is their written warranty on materials and workmanship? One year is standard; two years is better. Understand what triggers a warranty visit and what documentation they require.
Change order process: How do they handle scope changes — do they issue written change orders with pricing before proceeding, or do they add costs verbally and invoice later? Verbal scope changes on commercial projects create disputes.

Glazing Scope Clarity: What Your Subcontract Must Define

Glazing disputes on commercial projects almost always trace back to scope ambiguity. Before executing the subcontract, confirm in writing who is responsible for:

Perimeter sealants: Is the glazing sub responsible for the final weatherseal between the frame and the surrounding substrate, or does that fall to a caulking trade? Define it explicitly.
Temporary protection: Who supplies and maintains protective film on glass after install until substantial completion? Glass is one of the most frequently damaged finishes on a busy commercial site.
Crane and hoist access: For large-format or high-elevation glazing, who coordinates and costs the crane pick? If the GC is providing the tower crane, define the number of picks and time windows available.
Hardware supply: Confirm whether hardware (pulls, locks, hinges, closers) is supplied by the glazier or specified by the architect and supplied by the owner. Misunderstandings here delay final hardware installation regularly.

Glazing Systems Relevant to Large Metro Vancouver Projects

Large commercial projects in Metro Vancouver typically involve one or more of the following glazing systems, each with different coordination and specification requirements:

Aluminum storefront: The workhorse of mid-rise commercial glazing. Thermally broken systems are now baseline in BC given Step Code energy requirements. Confirm the system specified meets BC Energy Step Code 3 or higher if required by the building permit.
Glass office partitions: Full-height demountable or fixed glass walls within the tenant improvement scope. Specify whether the system needs acoustic performance (STC rating) and what the floor track integration requirement is.
Structural glass railings: Interior and exterior guardrails using 12mm or 17.5mm laminated tempered glass panels. Ensure the glazing sub provides PE-stamped shop drawings for any exterior structural glass railing application.
Shower and amenity glazing: Frameless shower enclosures for multi-unit residential projects. Coordinate these with plumbing and tile completion milestones — glazing can't template until tile is done.

Working with WaveGlass on Commercial Projects

WaveGlass works directly with general contractors and construction managers on commercial, strata, and institutional glazing scopes across Metro Vancouver — including Burnaby, Richmond, Coquitlam, Vancouver, Surrey, and Port Moody.

We provide full documentation packages (insurance, WCB, safety plans, product specs) during pre-qualification, issue formal written change orders before proceeding on scope changes, and maintain a direct relationship with BC-based fabricators for schedule reliability. We're available for pre-construction schedule reviews and will flag lead time conflicts before they become your problem.
