Contractor is entitled to reasonable compensation for extra work beyond contractual quantities when the department fails to fix rates.

The State of Gujarat, through its Irrigation Department, awarded the respondent-contractor a contract for earthwork and lining of a canal under Agreement No. LCB.6 of 1988–89, valued at Rs.5,28,208.23, with completion scheduled within eleven months from 28 July 1988.

The contractor alleged that the State delayed handing over the site, required additional excavation of hard and soft rock, and compelled him to procure earth from beyond the contractual 50-metre lead because a nearby borrow pit was unavailable.

He also claimed escalation, overheads, overstay expenses, loss of profit on unexecuted work, refund of deductions, and interest, totalling Rs.5,31,399.60.

The work was completed after extensions, and the final bill was paid; the State contended that the contractor had accepted the payment and had undertaken not to raise further claims.

The trial court awarded Rs.4,43,376.57 with 15% interest. The State challenged that decree under Section 96 of the Code of Civil Procedure, 1908.

1. Whether the contractor was entitled to additional payment for executing earthwork beyond the contractual 50-metre lead and for excavating quantities of hard and soft rock exceeding the contractual limits.

2. Whether the contractor was entitled to compensation for delay, price escalation, overhead and overstay expenses, and loss of profit on unexecuted work.

3. Whether the contractor’s acceptance of the final bill and undertaking not to pursue further claims barred the suit, particularly in the absence of substantiated coercion or duress.

4. Whether the trial court was justified in awarding interest at 15% per annum and including an interest component in the principal decretal amount.

The appeal was governed by Section 96 CPC, which permits an appellate court to examine the correctness of a decree.

The contractual clauses governing excess quantities and extra items—particularly Clauses 31 and 32—required rates for work beyond the stipulated quantity or scope to be mutually agreed.

Applying the principle reflected in Union of India v. Khetra Mohan Banerjee, the court held that where the employer permits extra work without rejecting the contractor’s rate claim within a reasonable time, it cannot subsequently impose its own rate after the work has been completed.

Section 23 of the Contract Act was relevant to the challenge against an undertaking obtained under coercion; however, the court found that the claim of coercion was not sufficiently supported by evidence.

Compensation for delay, overheads, overstay expenses and loss of profit must be proved by cogent evidence and cannot rest on pleadings alone.

Interest must be reasonable and, where the contract contains no applicable interest term, cannot automatically be fixed at the rate claimed or awarded by the trial court.

The court upheld the award for extra work because the State accepted that the contractor had performed excavation beyond the contractual quantities and had brought earth from beyond the 50-metre lead.

The contractual threshold of 130% had been substantially exceeded, yet the department neither mutually settled revised rates nor rejected the work; consequently, payment at reasonable rates was justified under Clauses 31 and 32.

The State’s inability to provide a nearby borrow pit was also effectively admitted, and the contractor had notified the department of the rate claimed before completion of the work.

In contrast, the claims for escalation, delay-related overheads, overstay expenses and loss of profit were rejected because the contractor had accepted extensions and the final bill, and had produced no adequate evidence establishing the alleged losses.

The court further disapproved the trial court’s inclusion of Rs.55,300.27 as interest in the principal amount and reduced the applicable interest rate, since the contract was silent on interest for extra work.

The contractor was held entitled only to Rs.2,14,541.55 for earthwork beyond the 50-metre lead, Rs.88,717 for extra hard- and soft-rock excavation, and Rs.5,500 towards refund of the security deposit, aggregating to Rs.3,08,760.

The award of compensation for delay, escalation, overheads, overstay, and loss of profit was set aside.

The trial court’s 15% interest award was modified, and the decretal amount was directed to carry interest at 8% per annum from the date of the suit until realization.

No order as to costs was made; any amount deposited by the State was to be adjusted against the modified decree, with the balance refunded to the State.
