Technical Skills

Can you describe the process you follow to measure and cut glass for a custom window?
Situation

I was assigned a custom storefront project for a boutique retailer.

Task

I needed to accurately measure the opening and cut tempered glass to fit the design specifications.

Action

I first measured the rough opening twice using a steel tape, then marked the exact dimensions on the glass with a permanent marker. I set up the glass cutter, aligned the blade, and made a clean score line, followed by a controlled break using a suction cup. I double‑checked the finished piece against the opening before delivery.

Result

The glass fit perfectly on the first try, the client approved the installation, and the project stayed on schedule, saving the crew an extra day of labor.

What are the key steps in preparing a frame for glass installation?
Situation

During a recent office renovation, I was responsible for installing new office partition glass.

Task

Prepare the metal frames so the glass could be set securely and sealed properly.

Action

I first removed any old sealant and debris, inspected the frame for dents, and applied a primer to the contact surfaces. I installed the glazing beads, ensuring they were level, and applied a silicone sealant to create a watertight seal before placing the glass.

Result

The glass panels were installed without movement, the seal held for months with no leaks, and the client praised the flawless finish.

Safety & Compliance

How do you ensure safety when working at heights on a construction site?
Situation

I was tasked with installing glass panels on a six‑story commercial building.

Task

Maintain personal safety and comply with OSHA regulations while working on the scaffold.

Action

I performed a pre‑task safety briefing, inspected the scaffold for proper planking and guardrails, used a full‑body harness attached to a secure anchor point, and employed a spotter when handling large glass sheets. I also kept a rescue plan ready and documented all safety checks.

Result

The installation was completed without any incidents, passed the site safety audit, and the crew received commendation for zero‑recordable injuries.

How do you stay current with building codes and industry standards related to glazing?
Situation

Our company updates its glazing practices annually to meet new energy‑efficiency codes.

Task

Ensure I am aware of the latest code changes and apply them to my daily work.

Action

I subscribe to the Glass Association of North America newsletters, attend quarterly webinars on the International Building Code updates, and review the latest local amendments before each project. I also share key changes with teammates during our weekly toolbox talks.

Result

My projects consistently meet or exceed code requirements, reducing re‑work and earning positive feedback from inspectors.

Tell us about a time you dealt with a difficult customer who was unhappy with a glass installation.
Situation

A homeowner complained that the newly installed patio door glass had a visible crack after a week of use.

Task

Resolve the issue promptly while maintaining the client’s trust.

Action

I listened actively to the homeowner’s concerns, apologized, and inspected the installation. I discovered a stress point caused by improper framing. I arranged for an immediate replacement, coordinated with the framing crew to correct the issue, and offered a complimentary cleaning service as goodwill.

Result

The homeowner was satisfied with the swift resolution, left a positive review, and referred two additional clients to our company.

Task

Address the defect without delaying the client’s opening schedule.

Action

I documented the crack, consulted the manufacturer’s warranty, and coordinated with the supplier for an expedited replacement. I prepared a temporary protective barrier, removed the cracked pane using suction lifts, and installed the new glass with reinforced glazing beads. I also performed a final inspection and provided the client with a warranty certificate.

Task

Synchronize glazing installation with electrical conduit placement and carpentry framing to avoid rework.

Action

I scheduled a joint pre‑construction meeting, created a shared Gantt chart, and marked clearances on the shop drawings. I communicated daily with the electricians to confirm conduit locations before installing the glass, and worked with carpenters to ensure framing tolerances met glazing specs. When a conflict arose, I facilitated a quick on‑site solution by adjusting the bead depth and rerouting a conduit segment.
