Ahmedabad’s Rs 283 Crore Digital Twin: The Test Is Upkeep
Sixty of the 90 months in the contract for the Ahmedabad digital twin project are set aside for operation and maintenance, according to the World Bank notice that invited bids.[4] That ratio says more about the project than the Rs 283 crore headline. Ahmedabad Municipal Corporation (AMC) is not only buying a 3D picture of the city. It is paying for a property and utility database to be kept alive for five years after the survey ends.
The contract was awarded on 21 September 2026 to two named bidders, Tojo Vikash International and Genesys International, and Genesys told the stock exchanges about it on 24 September, a filing that ET Infra reported the same day.[1][2][17] This article separates what the public documents confirm from what AMC has reportedly planned and from what nobody has published yet. It does not repeat the general explainer on city twins, which is in our survey of digital twin adoption in Indian cities. We have not seen the tender’s technical annexures or the signed contract, so everything below rests on public notices, filings and press reports.
Fact box: one contract, two price figures, a 90-month clock
| Item | What the public record says | Source and date |
|---|---|---|
| Client | Ahmedabad Municipal Corporation (AMC), a domestic order for Genesys | Genesys filing, 24 Sep 2026[2] |

| Selection method | International competitive bidding, with 70% of the marks for non-price criteria and 30% for bid cost | Bid invitation, 23 Apr 2025[4] |
The two price figures probably differ by tax alone
Genesys describes the order as Rs 283 crore inclusive of taxes.[2] The World Bank’s award notice lists a signed price of about Rs 240.21 crore.[1] Adding 18% GST to Rs 240.21 crore gives roughly Rs 283.4 crore, which matches the filing once rounded.
“World Bank-funded” means part of the proceeds of an IBRD loan
Genesys’s filing and release both call the contract World Bank-funded.[2][3] The Bank’s own bid invitation is more careful: AMC has received financing and “intends to apply part of the proceeds” to payments under the contract.[4] The financing sits under the Gujarat Resilient Cities Partnership: Ahmedabad City Resilience Project (P175728), a US$280 million IBRD loan within a project costed at about US$400 million, approved on 22 November 2022 with a closing date of 31 December 2028.[5]
Ahmedabad has mapped itself before, and the earlier maps could not be merged
Times of India reported in April 2025 that AMC’s earlier mapping efforts were scattered: a consultant mapped the water network in 2014-15, another mapped properties in 2015-16, and a third handled water connections. Officials told the paper that none of this sits on one platform or can be merged, and that the 2016 data is obsolete.[9] The Bank’s 2022 appraisal describes the same gap, noting that the city’s existing assets lack geocoding and GIS integration.[6] AMC’s current plan is also reported to update a GIS dating from 2014.[8]
Read against that history, the main deliverable is a shared system of record, and the 3D model is one layer on top of it. The Bank’s appraisal shows how it intended to judge success. One results indicator pays US$11.11 for each of up to 900,000 active properties geocoded by 31 December 2027, and verification means retrieving the property’s tax record from the GIS database.[6] Another covers digitising and ground-truthing 1,700 km of sewer pipes, 6,000 manholes, 20 pumping stations, 6 sewage treatment plants and 750,000 connections by 30 September 2028.[6]
Those 2022 targets are well below the contract’s 25 lakh properties and the roughly 3,400 km sewer network described in the bid invitation, and the appraisal says its quantities would be updated after a baseline survey.[4][6] We do not treat them as the contract scope. They do show how the lender defines success: records that can be retrieved and checked on the ground, not a model that looks impressive.
A 3D map, a GIS and a digital twin answer different questions
The three terms are often used as if they were interchangeable. In the Ahmedabad documents they describe different layers, and the table keeps them apart.
| Term | What it is | What keeps it current | Question it answers | What the Ahmedabad documents say |
|---|---|---|---|---|
| 3D map | A geometric model of terrain, roads and buildings built from aerial and street-level capture | Periodic re-survey | What does the city look like, and how tall, wide or steep is it? | Aerial survey and an elevation model from orthophotography[3]. Press reports of AMC’s plan add 30 cm terrain models, 5 cm true orthophotos and LOD-3 models of 500 key buildings[7][8] |
| GIS | A database in which each property, pipe or road has a location and attributes and can be queried | Permits, connections and repairs recorded as they happen | Which properties does this pipe serve, and when was it last repaired? | Property geocoding with unique identities[2] and mapping of underground utilities[1]. A press report adds 12 GIS applications linked to property tax, complaints and SCADA[7] |
| Digital twin | A GIS and 3D model fed by live data, able to run scenarios and tied to operations. The OGC’s CityGML 3.0 standard, for example, supports dynamic data from sensors and simulations[13] | Continuously | What is happening now, and what happens if a drain fails or a road closes? | The Bank notice uses the term[1], but we found no document describing live sensor feeds or simulation. Reported SCADA links are a plan, not a delivered feature[7] |
On the documents, the Ahmedabad contract is best described as a 3D GIS platform with a twin-ready base. That is a foundation rather than a lesser product. A twin without clean property and asset identities has nothing to attach live data to, which is also why the 3D layer is the least decisive part of the award. For how 3D models and GIS are used once they exist, see how 3D building models and GIS support emergency response.
Confirmed scope is narrower than the plausible uses
The table below labels each topic three ways. “Confirmed” means a notice or filing says it. “Plausible use case” is our analysis of what the data could support. “Not confirmed” means we found no public source.
| Topic | Confirmed | Plausible use case | Not confirmed |
|---|---|---|---|
| Property identity | About 25 lakh properties surveyed, geocoded and given unique digital identities[2] | Checking property-tax records against the ground. AMC has reportedly described a “digital door ID” for tax verification[7][8] | ID format, whether it links to the national land-parcel ID, how new buildings get IDs, who can look IDs up |
| Underground utilities | Mapping of “existing underground utilities”[1]; Genesys lists water, sewerage, stormwater and cable networks with location and depth[3]; the bid invitation cites a sewer network of about 3,400 km[4] | Checking what lies below before a road is dug. A Times of India report quotes an AMC official on GIS approval before infrastructure work[9] | Positional and depth accuracy, survey method, coverage by utility (a press report also lists gas lines), who verifies |
| 3D city model | Aerial surveys to create a 3D digital twin; elevation model from orthophotography[1][3] | Planning, permit review and flood-risk visualisation, as reported for Varanasi[12] | Level of detail and accuracy required by the contract. The 30 cm and 5 cm figures come from press reports of AMC’s plan |
| Live operations | Nothing specific in the notice or the filing | Drainage and emergency planning, if feeds from SCADA, complaints or a command centre were connected | Any live feed, command-centre link, simulation or delivery date |
| Keeping data current | 60 months of operation and maintenance inside the 90-month duration[1][4] | Annual satellite imagery with machine-learning change detection, as reported[7][8] | Update cadence, service levels, acceptance criteria, data ownership, platform access for departments and the public |
| Cost split | Total price only | Not applicable: we make no per-property or per-km cost comparison | Split between survey, software and five years of O&M; each bidder’s share |
Five steps from door to database, and where each one fails
The lifecycle below is our own illustration of how city-scale spatial data is generally built and kept. It is not the project’s documented design, and the failure notes are common risks rather than findings about Ahmedabad.
Survey. Aerial imagery gives coverage, but only ground truthing confirms the attributes. The Bank’s appraisal defines ground truthing as verifying mapped information on the ground.[6] India’s NAKSHA programme splits the work in a similar way: Survey of India supplies aerial surveys and orthorectified imagery, and states then carry out field surveys and ground truthing before records are published.[16]
Geocoding and identity. In the appraisal, geocoding means selecting a property’s polygon on a map from the address in the tax database.[6] The match is only as good as the address records. A national comparison is the 14-digit land-parcel ID (ULPIN, also called Bhu-Aadhaar) under the DILRMP 3.0 programme, described by PIB on 10 September 2026.[15] No source we found says Ahmedabad’s “unique digital identity” is a ULPIN.
Asset data model. For sewers, the appraisal lists pipe ID, diameter, section length, material, year of installation and start and end manholes, and keys each connection to the property code in the tax database.[6] That link is what lets a drainage record and a tax record refer to the same plot. It is a 2022 specification for a results indicator, not the contract’s data model.
Quality assurance. For property records, the Bank’s test is whether the record can be retrieved from the GIS database.[6] For underground assets, accuracy is the hard part. ASCE 38-22, summarised by the US Federal Highway Administration, grades utility data from quality level D (records only) to A (exposed and measured), with level B using surface geophysics to find position.[14] It is a US standard, not an Indian requirement, but it gives a vocabulary for what “mapped” means, which can range from a records overlay to a verified position.
Municipal workflows. The appraisal funds a GIS centre in AMC’s e-Governance department and training for three user departments, which is where the data either becomes routine or does not.[6] The same logic applies to command centres: a map only helps a control room if its data is current, as our guide to command and control centres explains.
Varanasi’s twin covers 160 sq km, and Ahmedabad’s is nearly four times the area
Times of India reported that Varanasi’s 3D twin covers 160 sq km, took about nine months and is integrated with the city’s command centre.[12] Ahmedabad’s reported 625 sq km is about 3.9 times that area, and its build is planned for about 30 months, with five years of upkeep after that.[2][3] The two differ in emphasis. Varanasi’s twin is tied to the command centre, and its flood-planning use is covered in our survey of digital twin adoption in Indian cities. Ahmedabad’s documents lead with property and sewer records. Neither is better; they serve different departments first. The comparison is for trade-offs only, and we make no cost comparison.
Area also needs a definition. AMC’s limits are 480.88 sq km, according to Times of India and Indian Express.[10][11] Times of India says the aerial survey covers 625 sq km “including the city and surrounding areas”, while Construction World calls it the municipal area.[7][8] The boundary used in the contract is not public, and the property count, the survey effort and any per-area promise all depend on it. For the wider context of urban programmes, see where the Smart Cities Mission stands in 2026.
Five questions that decide whether the twin is still useful in year five
Because 70% of the bid marks went to non-price criteria, the technical proposals carried most of the decision, and those proposals are not public.[4] That is a reason to ask AMC for the commitments behind the headline. These are our recommendations, not requirements found in any document.
- Accuracy is a number, not an adjective. What positional accuracy and level of detail does the contract require for buildings, roads and each utility, and how is that tested before payment is released?
- Ownership decides the exit. Who owns the raw data, models and identifiers, in which open formats (CityGML is one example), and can other departments and the public get access?
- Updates need a named owner. How often is the database refreshed, who records a new building, connection or repair, and what happens when a department does not report a change?
- Interfaces matter more than promises. Which existing systems, such as property tax, complaints, SCADA and the command centre, will exchange data with the platform, through what interfaces and by when?
- Year six needs a budget. What does the five-year O&M price cover, what service levels apply, and who funds the platform after the loan closes?
Trisim’s view: judge the twin by its year-five data
In Trisim’s view, the useful measure of any city twin is not how detailed the model looks at handover but how much of it is still correct, and still used, in year five. Property identity and utility records behave like a living register with named owners for every update, and a 3D layer adds value only once that register is trustworthy. The public record is still too thin to judge which of these Ahmedabad will turn out to be.
