Measurement and Payment

Measurement and payment is the core mechanism by which money moves from government to contractor in Indian works contracts. The contractor executes work on site, the department measures what has been done against the Bill of Quantities, and payment is released based on those recorded measurements. Every rupee paid to a contractor on an item rate contract flows through this process.

What is Measurement and Payment in government procurement?

Under GFR 2017 and the CPWD Manual, payment for works is strictly based on actual quantities executed, not on the contractor's invoice or self-declaration. The process follows a defined sequence for each Running Account (RA) Bill:

The contractor completes a defined portion of work and requests measurement. A junior engineer from the department visits the site and records measurements in the Measurement Book (MB), an official bound register that is a statutory document. Joint measurement, where the contractor's representative and the department's engineer measure together and both sign the MB, is the preferred practice and often mandatory for high-value items. Once measurements are recorded, the engineer prepares an abstract: quantity executed multiplied by the contracted unit rate gives the amount payable for each BOQ item. The accounts wing then checks the RA bill against the approved BOQ and any deductions (retention money, recoveries, TDS) before releasing payment.

The Measurement Book is the single most important document in a works contract. It is a permanent government record, subject to audit by CAG, and any erasure or overwriting requires countersignature from a senior officer. Fabricating measurements is a criminal offence under the Prevention of Corruption Act.

For large works, a dedicated Assistant Engineer or Executive Engineer handles measurements. On highway projects under NHAI contracts, an Independent Engineer (IE), a third party appointed by NHAI, records and certifies measurements, adding a layer of objectivity.

Why it matters for bidders

Payment delays in Indian government contracts almost always trace back to the measurement-and-payment cycle. If measurements are not recorded promptly, the RA bill cannot be submitted. If the accounts wing raises objections, payment is held. Contractors must maintain pressure to get measurements recorded and bills processed within the contractual timeline, which is typically 30 days from submission though reality often stretches to 60-180 days.

Contractors should keep their own parallel measurement records. Disputes over quantities are common, and having independent records of what was executed, supported by photographs with timestamps and GPS coordinates, strengthens the contractor's position in any arbitration. Unit rates in the BOQ are fixed, so the only variable is quantity, making measurement disputes the primary source of payment conflict in Indian works contracts.

Retention money of 2.5-5% is deducted from every RA bill and held as security until defect liability obligations are met. Contractors must factor this into working capital planning.

Example

A road contractor is building a 10-km state highway under an item rate contract. After completing the earthwork for the first 3 km, the contractor requests measurement. The Junior Engineer visits the site, measures the earthwork volumes using cross-sections at 25-metre intervals, and records dimensions in the Measurement Book. The quantity comes to 45,000 cubic metres. At the contracted rate of Rs 180 per cubic metre, the gross RA bill is Rs 81 lakh. After deducting 5% retention (Rs 4.05 lakh) and 2% TDS (Rs 1.62 lakh), the net payment due is approximately Rs 75.33 lakh. The contractor submits the RA bill with the signed MB extract, and payment is released after accounts verification.

Key rules / thresholds

The Measurement Book must be maintained in the prescribed government format; loose sheets are not acceptable. For items where measurement after execution is impossible, such as reinforcement steel embedded in concrete, measurements must be recorded before concealment. If this is missed, the contractor loses the right to claim that quantity. Payments above Rs 10,000 must be made electronically (PFMS or state equivalent) and cannot be made in cash under GFR 2017.
