For residential, commercial and industrial buildings
RA bill software for building contractors
Measure towers floor by floor and bill steel from the bar bending schedule. The developer's PMC checks each line against its drawing and photo instead of cutting it.
Floor-wise and tower-wise quantities
Each slab, beam and column entry carries its tower and floor. The bill shows the breakdown the PMC asks for, without a second sheet.
- The drawing number and revision on every entry
- Floors cast this month, tower by tower
| Floor | Tower A | Tower B | Total cum |
|---|---|---|---|
| Floor 11 | 86.40 | 84.20 | 170.60 |
| Floor 12 | 86.40 | 84.20 | 170.60 |
| Floor 13 | Not cast | 84.20 | 84.20 |
Steel billed from BBS weights
Bar marks, diameters, numbers and cutting lengths become weights at d x d / 162 kg a metre. The BBS travels with the bill.
| Bar mark | Dia mm | Nos | Total length m | Weight kg |
|---|---|---|---|---|
| S11-B1 | 8 | 640 | 2,048.00 | 808.96 |
| S11-B2 | 10 | 420 | 1,743.00 | 1,075.43 |
| S11-T1 | 12 | 310 | 1,984.00 | 1,763.78 |
| B11-M1 | 16 | 96 | 753.60 | 1,190.69 |
Evidence the PMC can check
The PMC opens any line in the bill room, sees its measurement and photo, then certifies it, certifies part or holds it.
- Drawing reference
Each entry names the drawing and revision it follows.
- Photo and date
Taken in the app when the work is measured.
- Logged cuts
Every part-certified line keeps its reason and who cut it.
| Item | Description | Claimed | Certified | Status |
|---|---|---|---|---|
| 3.4 | RCC M30 slab, floor 13cum | 84.20 | 84.20 | Certified |
| 3.6 | RCC M30 columns, floor 13cum | 18.60 | 18.60 | Certified |
| 4.2 | Reinforcement, Fe 500D, BBS S11kg | 4,838.86 | 4,838.86 | Certified |
| 5.1 | Blockwork 200 mm, floor 11cum | 42.30 | 38.10 | Part |
| 7.2 | Gypsum plaster, floor 10sqm | 1,240.00 | 1,000.00 | Part |
Questions
What building contractors ask before they move a tower onto Tatha Vastu.
Can it follow our developer's bill template?
Yes. Send one past bill in the developer's format. We set it up during onboarding, and every bill after that comes out in it.
How is steel billed?
From the bar bending schedule: bar mark, diameter, numbers and cutting length give the weight. The BBS is attached to the bill it was billed on.
What about cement and steel the developer issues?
Issued material is entered once and reconciled against theoretical consumption on every bill, so an excess shows before the PMC finds it.
Does the PMC pay to use the bill room?
No. The PMC and the developer's QS team check and certify bills submitted through Tatha Vastu free.
Can we bill part rate for unfinished work?
Yes. Bill an item at a reduced rate pending completion, then move it to full rate on a later bill. Both stay on the record.
