What this job shows
MAX runs the same Thai-system dies — a developer's budget can be met by choosing the profile brand while the section stays the same.
Each of the 40 windows has its own cutting sizes and bar nesting — cut only after approval.
Reflective glass cut to size from stock sheets, nested to keep sheet waste down — the calculator's job.
The film stays on the windows in the photograph — it comes off once the construction dust and paintwork are done.
Four flats in stages, following the site's finishing sequence.
The final bill follows the 40 openings measured on site, with a Mushak-6.3 challan.
One window, by this job's rule
An ordinary two-leaf window, height × width 1524 × 1219 mm: each side rounded up to the next half-foot — 5 ft × 4 ft = 20 sft. Forty windows of their own sizes add up to the billed 895 sft.
The General model starting rate is on the rate card; this job's contract sum is not published. The site's quick quote does the same arithmetic on your own sizes.
How a developer's four-flat job runs
- After the work order and advance, per-window measurement in every flat — height × width, 40 openings.
- Each window's cutting list and bar nesting approved in writing; glass sizes nested sheet by sheet.
- Fabrication in our own workshop, glass cut in the godown; installation flat by flat — the first windows are in.
- At handover the film comes off and every sash and lock is operated; final bill on actual sizes.
