Project Overview

Bifolding Door Installation in Quezon City

On October 30, 2026, the team reported bifolding door installation in Quezon City for a project at U.P. Diliman under client Engr. Norwin.

The installation scope comprised four bifolding doors, originally configured with ten panels each, across the interior openings shown in the project photographs.

One door was found to be oversized for the required opening, prompting the team to adjust its dimensions and remove one panel.

Engr. Glen de Vera inspected the items, while the project update also identified a hardware component that still requires replacement.

Project Progress

Installation Adjustment and Pending Hardware Replacement

The recorded work includes installation activity for four bifolding doors and the adjustment of one oversized assembly to fit its designated opening.

The hardware replacement remains pending confirmation in the supplied report, and the final completion of the bifolding door installation has not been verified.

The project therefore remains an installation update rather than a completed-project announcement until the remaining hardware issue and final status are confirmed.
