1. The Cost of Billing Delays in Indian EPC
For EPC and subcontracting firms executing projects for Public Sector Undertakings (PSUs) and government bodies, cash flow is dictated by the speed of Running Account (RA) Bill certification. In a survey of over 120 industrial contractors across India:
- Average RA Bill cycle from field execution to payment credit: 42 days.
- Primary cause of payment hold-up: Discrepancies in Measurement Sheets (MB).
- Average retention deducted by client accounts for unverified measurements: 5% to 10%.
Contractors who maintain standardized, digital, cumulative measurement records cut approval cycles from 42 days down to 8 days.
2. Anatomy of a Legally Compliant CPWD Form 23
CPWD Form 23 (and its defense counterpart under MES SSR) requires strict tabular accounting for every certified item of work:
| Column | Field Name | Description |
|---|---|---|
| 1 | Item Rate Code | Exact schedule item reference (e.g., DSR / SSR item code) |
| 2 | Description of Work | Full specification including material density, thickness, and standard |
| 3 | Location / Line Identifier | Iso number, line loop, equipment tag (e.g., E-104 Channel Head) |
| 4 | No. of Units | Number of identical segments |
| 5 | Dimensions (L × B × D) | Length, breadth/circumference, and depth/height in meters |
| 6 | Total Quantity | Product of dimensions |
| 7 | Previous Certified Qty | Cumulative sum approved up to previous RA Bill |
| 8 | Current Bill Qty | Net executed in current billing cycle |
3. Preventing Cumulative vs. Current Measurement Errors
The most frequent audit objection from client Resident Engineers is quantity over-run against tender provisions. When multiple site supervisors maintain individual spreadsheets, duplicate entries for the same pipe rack or tank shell occur frequently.
By implementing centralized database tracking:
- Every isometric line segment or vessel tag is assigned a unique system identifier.
- The moment an engineer logs a daily DPR entry, the system checks whether the cumulative executed quantity exceeds the tender BOQ ceiling.
- If executed work exceeds approved scope, an automated change-order alert is triggered before RA bill generation.
4. Digital JMR Records with Photo Evidence
Joint Measurement Records (JMR) require physical signatures from both the contractor's site engineer and the client's Engineer-In-Charge (EIC).
Using the VAYUXI mobile app, engineers record the completed work against each mark or line on the day it is done, with photos and the date and time of the entry. When the joint measurement is taken, both sides work from the same dated record instead of reconstructing quantities from memory.
5. One-Click Abstract & Tax Invoice Generation
Once the Measurement Book is signed, VAYUXI automatically compiles the Abstract of Quantities and generates the GST Tax Invoice complete with correct HSN/SAC codes (e.g., HSN 6806 for mineral rockwool thermal insulation).
