TL;DR

AAI manages 125+ airports across India as a Miniratna Category-1 CPSE under the Ministry of Civil Aviation. It accepts insurance surety bonds as a valid alternative to bank guarantees for both bid security and performance security, and the February 2022 GFR amendment and September 2024 DFS directive apply directly to every AAI tender.
Insurance surety bonds are permitted for EMD only when the EMD amount exceeds Rs. 10 lakh. Below that threshold, online CPP portal payment is the only route. For any meaningful airport construction, BHS, or O&M contract, the EMD routinely runs well above this level. The Kolkata NSCBI Airport pavement tender alone carried an EMD of Rs. 2.48 crore.
AAI's Additional Terms and Conditions (ATC) also confirm that performance bank guarantees can be submitted as insurance surety bonds, but with a specific validity requirement: the bond must remain valid for 90 days beyond the date of completion of all contractual obligations, not just the contract period. Contractors who approach their insurer without accounting for this will end up with an under-validity bond that AAI can reject.
Unlike SECI, AAI has not published a standardised ISB proforma. The bond must be issued by an IRDAI-registered insurer in a format consistent with GFR requirements. If a tender's SBD is silent on ISBs or restricts security to bank guarantees only, GFR Rule 171(i) and the DFS September 2024 directive provide the legal basis to push back.

Introduction

India is in the middle of one of the largest airport infrastructure build-outs in its history. AAI's annual procurement spans hundreds of tenders: runway construction, terminal expansion, baggage handling systems, electrical and mechanical installations, ATC towers, and long-term O&M contracts. All are issued through the Central Public Procurement (CPP) portal and governed by the General Financial Rules (GFR) 2017.

For most contractors in this space, bank guarantees have been the default instrument for bid security and performance security. That is changing. Insurance surety bonds are now accepted at AAI under the same regulatory mandate that covers every other central government CPSE. AAI's own tender documents confirm this in specific, operational language.

This article covers what that acceptance means for aviation sector contractors: which types of security are covered, the specific threshold rule that most contractors miss, how the CPP portal submission process works, and what to do when an individual tender's SBD has not caught up with the regulatory mandate.

AAI and India's Airport Infrastructure Pipeline

Airports Authority of India (AAI) was established in 1994 under the Airports Authority of India Act and manages 125+ airports across the country, including international, domestic, and civil enclaves. It operates as a Miniratna Category-1 Central Public Sector Enterprise (CPSE) under the Ministry of Civil Aviation (MoCA).

AAI's procurement covers a wide range of works: civil construction (runways, taxiways, aprons, terminal buildings), baggage handling systems (BHS), electrical and mechanical installations, ATC infrastructure, IT systems, and long-term operation and maintenance contracts. All procurement is routed through the CPP portal (etenders.gov.in) and governed by GFR 2017 as a CPSE.

This CPSE status matters for insurance surety bonds. Every GFR-governed entity is covered by the Ministry of Finance's February 2022 amendment to GFR Rules 170 and 171, and by the Department of Financial Services (DFS) September 2024 directive on mandatory ISB acceptance. AAI has no procurement carve-out. The mandate applies to every tender it issues.

Insurance Surety Bonds Are Now Accepted in AAI Tenders

AAI accepts insurance surety bonds for both EMD (bid security) and performance security. This is confirmed directly from AAI's own tender documents, not inferred from the GFR mandate alone.

For EMD, the Kolkata NSCBI Airport rigid pavement tender (Tender ID: 2023_AAI_166303_1, estimated cost Rs. 223.57 crore) states: “Contractors may have the option to submit EMD in the form of Insurance Surety Bonds or Bank Guarantee (BG) -paper form from a Nationalized or any scheduled bank but not from Co-Operative or Gramin/Rural bank (scheduled or Non-scheduled banks), if EMD amount is more than 10.00 lacs.”

The BHS (Baggage Handling System) tender NIT (TI 84 Amendment) uses near-identical language: “If EMD amount is more than Rs. 10.00 Lakh, EMD may be submitted in the form of Insurance Surety Bonds from Insurance company registered with Insurance Regulatory and Development Authority of India (IRDAI).”

For performance security, AAI's Additional Terms and Conditions document (ATC) states: “Performance Bank Guarantee may be submitted in the form of Insurance Surety Bond and shall be valid for ninety (90) days beyond the date of completion of all contractual obligations of the contractor.”

The table below summarises acceptance by security type:

Security Type	ISB Accepted at AAI	Condition
EMD (Bid Security)	Yes	EMD must exceed Rs. 10 lakh
Performance Security (PBG)	Yes	Valid 90 days beyond contractual obligations

Both forms require the bond to be issued by an IRDAI-authorised insurer.

The Regulatory Framework Behind AAI's Acceptance

AAI's acceptance of insurance surety bonds is not a discretionary policy choice. It is a compliance obligation under three overlapping regulatory instruments.

The Ministry of Finance, Department of Expenditure, amended GFR Rules 170(i) and 171(i) in February 2022, placing insurance surety bonds at par with bank guarantees for bid security and performance security across all government procurement. As a GFR-governed CPSE, AAI is directly covered.

The Department of Financial Services (DFS) followed this in September 2024 with a directive making ISB acceptance mandatory at all central government departments and CPSEs. This directive removed any residual discretion at the entity level. A procurement officer cannot decline an ISB from an IRDAI-registered insurer on the grounds that the entity's internal policy has not been updated.

The IRDAI Surety Insurance Contracts Guidelines 2022, effective April 2022, authorise Indian general insurers licensed by IRDAI to issue surety insurance contracts. This creates the supply side of the instrument. There are now several large insurers actively writing surety bonds for AAI-level contracts.

Regulation	What It Requires	AAI Applicability
GFR Rule 170(i) (February 2022)	ISBs accepted at par with BGs for bid security (EMD)	Applies to all AAI tenders
GFR Rule 171(i) (February 2022)	ISBs accepted at par with BGs for performance security	Applies to all AAI tenders
DFS Directive (September 2024)	Mandatory ISB acceptance at all CPSEs	AAI is a CPSE; directly applicable
IRDAI Guidelines (April 2022)	Authorises IRDAI-licensed insurers to issue ISBs	Defines the issuing authority AAI tender documents require

This means that even where an individual AAI tender's Standard Bidding Document (SBD) has not been updated to explicitly include ISBs, the regulatory mandate already requires acceptance. Contractors who receive pushback at the field level can cite the GFR amendment and DFS directive in a formal representation.

The Rs. 10 Lakh EMD Threshold: The Rule Most Contractors Miss

The most operationally important detail in AAI's ISB acceptance framework is one that does not appear in the general GFR mandate: a threshold rule specific to AAI's tender conditions.

Insurance surety bonds are permitted as EMD only when the EMD amount exceeds Rs. 10 lakh (Rs. 10.00 lacs). Below this threshold, EMD must be paid online through the CPP portal payment gateway. The ISB route is not available for small-value tenders.

In practice, this threshold rarely limits aviation infrastructure contractors. Most civil works, BHS, and EPC contracts issued by AAI carry EMDs substantially above Rs. 10 lakh. A runway pavement contract worth Rs. 223 crore carries an EMD of Rs. 2.48 crore. A mid-size terminal renovation project will typically have EMD in the Rs. 25 lakh to Rs. 2 crore range. The threshold matters most for smaller O&M or annual rate contracts where the EMD may fall below Rs. 10 lakh.

EMD Amount	Permitted Forms
Up to Rs. 10 lakh	Online CPP portal payment only
Above Rs. 10 lakh	Online CPP portal; or Insurance Surety Bond; or Bank Guarantee (scheduled commercial bank)

Contractors who have historically been replacing EMD with insurance surety bonds in NHAI or SECI tenders will find the AAI framework familiar, with the added threshold condition to check before applying.

How AAI Tenders Handle ISB Submission

AAI's ISB submission process has two components: an online upload and an offline original. Both must be completed for the bid to be valid.

Online component: Contractors upload a scanned copy of the insurance surety bond in Cover-I (or Envelope-I, depending on the NIT format) on the CPP portal. This must be accompanied by a letter of undertaking as per Appendix-XIA of the GCC.
Offline original: The original physical insurance surety bond must be submitted to the Bid Manager at the AAI office address specified in the NIT, on or before the date and time stated in the Critical Data Sheet.
The 3-working-day window: AAI mandates a minimum 3 working-day gap between the bid submission end date and the last date for offline submission of original documents. Bid opening (Cover-I) is scheduled after this deadline. For example, in the Kolkata NSCBI pavement tender: bid submission closed on 29 September 2023; last date for original documents was 3 October 2023; Cover-I opening was 4 October 2023.
Rejection risk: AAI’s tender conditions are explicit: “The bidder, whose Insurance Surety Bond/BG against EMD are not received by the date and time mentioned in critical data sheet, then their tenders will be liable to be rejected. Any postal delay will not be entertained.” This is a hard deadline, not a soft guideline. Contractors who rely on courier delivery without building in enough lead time are exposed to disqualification.
EMD refund: Unsuccessful bidders have their EMDs refunded after submission of the technical/financial evaluation report on CPP portal by the Bid Manager. ISB and BG originals are returned by post. The successful bidder's EMD is released on receipt of performance security.

Aviation Contract Types Where ISBs Apply

Insurance surety bonds are confirmed across the full range of AAI procurement categories:

Contract Type	ISB for EMD	ISB for PBG	Notes
Civil works (runway, taxiway, pavement, apron)	Yes	Yes	Large EMDs; well above Rs. 10 lakh threshold
BHS (baggage handling system) SITC + O&M	Yes	Yes	EMDs often Rs. 50 lakh to Rs. 5 crore range
Electrical and mechanical (E&M) works	Yes	Yes	ARMO and capital works tenders
Terminal construction and renovation	Yes	Yes	Major airport expansion projects
ATC tower and specialised civil works	Yes	Yes	Specialist tenders follow same NIT format
O&M and AMC contracts	Yes	Yes	Annual rate maintenance orders

The BHS category is worth noting specifically. BHS contracts at major airports are among the largest AAI tenders by value, with contract periods running 15 to 18 years including operation and maintenance. The EMDs on these tenders are substantial, and the performance security obligations extend well into the O&M period. Getting the 90-day post-completion validity clause right from the outset is therefore critical for BHS contractors using ISBs as performance security.

Performance Security at AAI: The 90-Day Validity Rule

AAI's Additional Terms and Conditions (ATC) document confirms that performance bank guarantees may be submitted in the form of an insurance surety bond. The operative validity condition is that the bond must remain valid for 90 days beyond the date of completion of all contractual obligations of the contractor.

This is a longer validity window than the contract period alone. For a BHS contract with a 24-month Defect Liability Period (DLP) after SITC completion, the ISB used as performance security must remain valid 90 days past the end of that DLP. Contractors approaching their insurer for a performance security ISB need to specify this extended validity at the time of issuance and not attempt to extend it later.

Some AAI GCC versions carry older language that refers to performance security as a bank guarantee only. Where the NIT or ATC document explicitly permits ISBs as performance security, that language governs. Where the SBD is silent or uses BG-only language, GFR Rule 171(i) and the DFS September 2024 directive provide the regulatory override. Contractors encountering resistance at the field level can formalise a representation to the Bid Manager that: (1) cites the GFR Rule 171(i) amendment, (2) cites the DFS September 2024 directive, and (3) attaches the IRDAI licence certificate of the issuing insurer confirming authorisation to issue surety insurance contracts.

The underlying instrument works in exactly the same way as a performance bond used in other central government tenders: unconditional, irrevocable, and payable on demand. The only AAI-specific requirement is the 90-day post-completion validity window.

Frequently Asked Questions

Does AAI accept insurance surety bonds for EMD?

Yes. AAI accepts insurance surety bonds as EMD in tenders where the EMD amount exceeds Rs. 10 lakh. The bond must be issued by an IRDAI-registered insurer.

What is the EMD threshold for insurance surety bonds in AAI tenders?

The threshold is Rs. 10 lakh. If the EMD is Rs. 10 lakh or below, contractors must pay online through the CPP portal. Above Rs. 10 lakh, the ISB route is available as an alternative to online payment or a bank guarantee.

Can I submit an insurance surety bond for performance security in AAI contracts?

Yes. AAI's Additional Terms and Conditions confirm that performance bank guarantees can be submitted as insurance surety bonds. The bond must be valid for 90 days beyond the date of completion of all contractual obligations. Plan this validity window with your insurer before issuance.

What happens if the original ISB does not reach the Bid Manager before the Critical Data Sheet deadline?

The tender is liable to rejection. AAI's NIT conditions are explicit that postal delay is not entertained. Submit originals with adequate lead time. The 3-working-day window between bid submission close and the original document deadline is a minimum, not a comfortable buffer.

Does AAI have a standardised insurance surety bond proforma?

No. Unlike SECI, which publishes named proformas (Formats 16, 26, and 27) as tender annexures, AAI does not publish a standardised ISB proforma. The bond must be drafted by the issuing insurer in an unconditional, irrevocable format consistent with GFR requirements and the specific GCC conditions of the relevant tender. Work with an experienced insurer or a platform like axiTrust to ensure the bond wording is aligned before the offline submission deadline.
