At Infra Advisors, we understand that robust financial planning is the backbone of successful infrastructure projects. Our comprehensive financial advisory services are designed to address the unique complexities of infrastructure ventures, enabling our clients to make informed decisions and achieve sustainable growth. Whether you’re navigating funding challenges, structuring debt, or mitigating risks, our team provides the strategic expertise needed to unlock your project’s full potential.

DBFOT - Toll

Toll-based DBFOT remains the preferred model for high-traffic corridors, where revenue potential supports private financing. NHAI’s accelerated awarding under Bharatmala Phase I has kept toll project pipelines deep, with over ₹3 lakh crore in committed highway investment still under execution.

Infra Advisors provides end-to-end transaction advisory on toll DBFOT projects from traffic and revenue modelling to financial structuring, lender negotiation and bid document preparation. We have supported both concessionaires and lenders across competitive bid processes.

DBFOT - Hybrid Annuity

The Hybrid Annuity Model (HAM) has become the dominant procurement structure under NHAI, balancing construction risk with assured annuity payments. With a 40% upfront government contribution and the balance through annuities, HAM projects attract mid-sized developers and institutional debt, with defined cash flow visibility.

Our team advises on financial modelling, debt structuring and concession due diligence for HAM projects. We assist developers in optimising equity returns and support lenders in aligning financing structures to NHAI’s prescribed payment waterfall.

DBFOT - Annuity Project

Pure annuity projects underpin NHAI’s development of strategically important corridors where traffic volumes do not support toll-based financing. Government-assured annuity payments eliminate revenue risk, making these projects attractive to infrastructure-focused institutional investors.

Infra Advisors supports clients on annuity project bids through comprehensive financial modelling, O&M benchmarking and lender advisory. We structure debt packages aligned to annuity receipt schedules, helping clients optimise project-level returns within the NHAI framework.

DBFOT - Toll & Annuity

The toll-cum-annuity structure blends revenue certainty with user-fee upside, typically applied to mixed-traffic corridors. As NHAI refines procurement models to expand private participation, toll & annuity projects represent a growing share of the awarding pipeline.

We provide integrated advisory across the dual-revenue structure modelling toll flows alongside annuity receipts, structuring blended financing and advising on concession terms. Our experience spans both bid preparation and post-award lender syndication.
