Deviation & variation statements, done digitally
Deviation Statement Software for Railway & PWD Contractors
Stop rebuilding deviation statements in Excel before every bill. PRIME ERP keeps agreement quantities, executed measurements and rates in one place, and produces item-wise deviation statements, variation statements and revised estimates whenever you need them.
Item-wise deviation statements: agreement quantity vs executed quantity with amounts
Works with USSOR, DSR and non-schedule (NS) items
Variation statements for scope additions and substitutions
Revised estimates with sub-works and item-level detail
Measurements recorded once, reused across statements and bills
PDF outputs ready for submission to the department
How it works in PRIME ERP
Set up the agreement
Load your work order with schedule items, agreement quantities and rates — from USSOR/DSR masters or Excel import.
Record executed quantities
Site engineers record work order measurements as work progresses; everything stays item-linked.
Generate the statement
PRIME compares agreement vs executed item by item and produces the deviation statement as a clean PDF.
Example: a deviation statement for three items
The statement lists every item with its agreement quantity, the quantity executed, and the difference as excess or saving, both in quantity and in money.
| Item (example figures) | Agreement | Executed | Excess / saving | Amount | % of agreement |
|---|---|---|---|---|---|
| 1.1 Earthwork, ₹310/m³ | 850 m³ | 1,020 m³ | +170 m³ | +₹52,700 | 120.0% |
| 1.2 PCC 1:4:8, ₹5,600/m³ | 95 m³ | 88 m³ | −7 m³ | −₹39,200 | 92.6% |
| 2.1 RCC M25, ₹9,200/m³ | 260 m³ | 275 m³ | +15 m³ | +₹1,38,000 | 105.8% |
| Total | ₹31,87,500 | ₹33,39,000 | +₹1,51,500 | 104.8% |
Earthwork has run 20% over, but it is still below 125%, and the schedule as a whole is at 104.8%, so no SOP 2018 rate cut applies here. Had the group crossed 125%, the statement would show the deduction for that schedule.
The summary at the top of every statement
Agreement value, revised value, the variation and the net value after any rate cut sit in one row, so the engineer sees the result before reading the item list.
Deviation statement or variation statement
| Deviation statement | Variation statement | |
|---|---|---|
| Compares | Agreement quantity with executed quantity | Agreement quantity with proposed revised quantity |
| Used for | Showing where the work has gone over or under | Getting a change in scope sanctioned |
| New items | Not covered | Added as extra or substituted items |
Both read the same agreement and the same measurements, so a quantity entered once appears in both.
Where Excel goes wrong
- Agreement quantities retyped from the agreement, with one item missed or doubled.
- Executed quantities that do not match the measurement book or the last RA bill.
- The SOP 2018 check done item by item for SOR items, when the rule works on the schedule group.
Frequently asked questions
What is a deviation statement?
A deviation statement compares the quantities in the original agreement against the quantities actually executed, item by item, showing excess and savings. Departments typically require it before passing running or final bills when quantities deviate from the agreement.
Does PRIME ERP support both railway (USSOR) and CPWD/PWD (DSR) work?
Yes. PRIME ERP maintains both USSOR and DSR item masters with Excel import, and deviation statements work the same way for either schedule.
Can my site engineers enter measurements from the field?
Yes. PRIME ERP is a web app that works on any phone or tablet, with role-based access so site engineers can record measurements and progress without seeing financial data.
What other statements can it produce?
Variation statements, revised estimates with sub-works, work order measurement records, and 30+ financial and project reports — all as PDFs.
