Technical Skills
I was assigned a custom storefront project for a boutique retailer.
I needed to accurately measure the opening and cut tempered glass to fit the design specifications.
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.
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.

During a recent office renovation, I was responsible for installing new office partition glass.
Prepare the metal frames so the glass could be set securely and sealed properly.
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.
The glass panels were installed without movement, the seal held for months with no leaks, and the client praised the flawless finish.

Safety & Compliance
I was tasked with installing glass panels on a six‑story commercial building.
Maintain personal safety and comply with OSHA regulations while working on the scaffold.
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.
The installation was completed without any incidents, passed the site safety audit, and the crew received commendation for zero‑recordable injuries.

Our company updates its glazing practices annually to meet new energy‑efficiency codes.
Ensure I am aware of the latest code changes and apply them to my daily work.
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.
My projects consistently meet or exceed code requirements, reducing re‑work and earning positive feedback from inspectors.

Customer Interaction
A homeowner complained that the newly installed patio door glass had a visible crack after a week of use.
Resolve the issue promptly while maintaining the client’s trust.
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.
The homeowner was satisfied with the swift resolution, left a positive review, and referred two additional clients to our company.

During a post‑installation walkthrough for a new office lobby, a supervisor noticed a hairline crack in one of the floor‑to‑ceiling glass panels.
Address the defect without delaying the client’s opening schedule.
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.
The replacement was completed within 24 hours, the lobby opened on time, and the client praised the rapid response and professionalism.

Collaboration & Project Management
We were installing a glass curtain wall on a mixed‑use building that required coordination with the electrical team for integrated lighting.
Synchronize glazing installation with electrical conduit placement and carpentry framing to avoid rework.
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.
The curtain wall was installed on schedule, the integrated lighting functioned flawlessly, and the client commended the seamless teamwork.

A commercial client requested low‑E double‑glazed units to meet LEED certification goals for their new office building.
Select and install glazing that meets energy performance targets while staying within budget.
I consulted the manufacturer’s performance data, selected double‑glazed units with a low‑E coating and argon fill, verified U‑value calculations against the project’s energy model, and coordinated with the HVAC engineer to ensure compatibility. During installation, I used insulated glazing beads and ensured airtight sealing to prevent thermal bridging.
The building achieved the desired LEED points, reduced heating/cooling loads by 15%, and the client reported lower utility bills in the first year.
