The operator pays NDMC a fixed Reserved Monthly Licence Fee (RMLF) plus a quoted share of gross revenue, and carries all capex, staff, tow fleet and collection risk for 5 years with no termination payment. The released RFP fixes the lot-removal risk and makes the technical bar easier for a strong partner, but the core economics are unchanged and the timetable is now the binding constraint. Where the case stands: on NDMC's booked collections (about ₹1.9 Cr a month in 2025-26, against RMLFs totalling ₹6.4 Cr), every cluster runs short of its RMLF at RFP tariffs. The bid works if the survey or NDMC's site-wise data shows substantially higher real demand, or if NDMC moves on the RMLF through the pre-bid process. The consortium is preparing the full technical bid in parallel so both options stay open.

Monthly average of parking fees booked by NDMC, from the Detailed Statement of Receipts in each year's budget (₹ thousand, converted). 2025-26 is the first full year with NDMC's own staff running about 125 sites. The 2026-27 figure is the failed 2025 tender's ₹7 Cr floor written into the budget, not a forecast from collections.
How it is built: 5,597 offices, shops, restaurants, cafés, bars, hotels, museums, courts and government buildings from OpenStreetMap were counted within 450 m of each lot and blended 50:50 with the lot's segment. Each driver's hour-by-hour and day-by-day pattern now comes from Google Maps "Popular times" read on 23 Oct 2026 for 16 places: markets from Khan Market, Sarojini Nagar Main Market, INA Market, Janpath Market and Bengali Market; dining from Wenger's (CP) and Gulati (Pandara Road); nightlife from Warehouse Cafe (CP); culture from Dilli Haat, the Rail Museum and Central Park (CP); offices and courts from India Habitat Centre, the Supreme Court and Patiala House; transit from Rajiv Chowk metro. Hotels and residential lanes keep assumed patterns (Google shows none). Monthly seasonality stays assumed, with weddings lifting hotels November to February. On top sit 2027's festivals and events: Holi, Eid, Rakhi, Navratri, Karva Chauth, the Diwali fortnight, Christmas and New Year, Republic Day closures around Kartavya Path, Parliament sessions on Sansad Marg and GRAP work-from-home advisories in winter. The overall level is then scaled so that, at today's tariffs (₹20 an hour, ₹100 day cap, GRAP doubling for four months), the model reproduces NDMC's booked ₹22.4 Cr for 2025-26 after the selected leakage. The 2027 view then applies RFP tariffs with demand easing as prices rise (elasticity −0.25 off-street, −0.4 on-street).
Limits: OpenStreetMap under-records some places (it lists only 31 bars across NDMC), so each lot's mix is half map data and half segment. Hourly patterns are Google's relative busyness for nearby anchor places, not parking counts; Sarojini Nagar is closed on Mondays and the Rail Museum on Mondays, which the data reflects. Seasonal patterns remain assumptions. Festival dates are for 2027 (Holi 22 Mar, Diwali 29 Oct; Eid dates tentative). Use the survey to replace them.
Three demand sources. Calibrated to NDMC's books (default) uses the demand calendar below, scaled to NDMC's booked collections; Low / Base / High then mean 20%, 35% and 50% leakage in those books. Our segment estimates place each lot in a demand segment from its location and what it serves; paid hours per car space per day and the billed hours per visit are editable for each segment; the cluster results below use them together with the yield-loss, revenue-share, staff, towing, night and capex settings above. Two-wheelers are assumed at 80% of the car paid hours.
Today attendants take keys and move cars to fit more vehicles than the marked bays. Under the new contract that practice carries penalties: ₹5,000 per vehicle above the designated capacity (SLA 7.3) and ₹200 per vehicle not in a marked bay (SLA 7.2), and the IIPMS has to report occupancy to 99% accuracy. Choose how DSSG would run it; the result flows into every profit figure on this page.
Two checks. First, the internal logic model was given the raw evidence (RFP terms, NDMC's booked receipts by year, contract history, audit findings, DSSG's cost estimates) and asked the decision questions directly. To test how much the answers depend on what it sees, the same questions were asked three times: with all the evidence, without the audit findings, and with only the description of today's NDMC-run operation. Our own conclusions and model outputs were not sent. Second, each of the 153 lots with car bays was judged on its own against the average NDMC lot, using its name, type, bays and the OpenStreetMap places around it, with no figures from our model.
The first run asked each lot for its absolute occupancy without the booked collections. It put average occupancy at 55 to 75% and gross revenue at about ₹12.8 Cr a month. NDMC's books (₹1.87 Cr a month) contradict that; the run is superseded. Its peak-overflow estimates still feed the overflow section above.
Items follow the RFP's Financial Form 3 and the equipment it requires by lot type. Quantities are worked out from Annexure I site and space counts. Change any unit rate or quantity, for example with vendor quotes, and the break-even model above updates. Your edits are remembered in this browser only.
Capex is repaid as a 57-month loan at 11% (the O&M period), with no residual value because all assets pass to NDMC free at the end (ToR 3.3.5). Equipment warranty and upkeep for the full term sit in the running-cost line, not here.
Columns follow the RFP's prescribed query format. Section and page references are to the released RFP of 22 Oct 2026. The priority column is for internal use and is not included when you copy. Wording is a draft: review with the partner before sending, and submit under the bidder's name.
