Everything you'd ask about the AI digital twin for your site.

Delta Astra is a digital twin platform for the built environment. We capture your site — exterior and interior — build a measurable 3D twin, and give you progress tracking, CAD overlays, walkthroughs and survey-grade measurement in one portal, for industrial, infrastructure and real estate across Maharashtra.

We serve projects across Maharashtra including Pune, Mumbai, Nagpur, Nashik, Thane and Chhatrapati Sambhajinagar (Aurangabad), and take on larger programs elsewhere in India. Our base is Pune.

Yes. Delta Astra offers self-capture: anyone on site can capture in seconds and every capture is automatically geo-tagged to its location and flows straight into your twin. Self-capture, have our team capture, or mix both on the same project.

No. Delta Astra handles capture end-to-end and delivers everything through a browser-based portal — nothing to buy, operate or install on your side.

A survey-grade aerial land survey achieves 1–3 cm horizontal accuracy — comparable to a traditional total-station survey for most land, industrial, infrastructure and real estate survey use cases — while covering large sites in hours. Every deliverable states its accuracy.

For most land and construction sites an aerial survey matches total-station accuracy while covering far more ground per day and producing a full visual record you can revisit. Traditional survey still wins for a few dense-canopy or single-point tasks, so we scope each project honestly.

An aerial pass reconstructs the stockpile surface, a base plane is set, and volume is computed automatically. Results are repeatable and typically within ±2–3% — accurate enough to reconcile inventory, plan production and certify bills against.

We difference the captured terrain surface against a design or earlier surface to produce cut-and-fill quantities and a heatmap of where material moved — used for earthwork billing and grade verification.

We capture your site on a fixed cadence, exterior and interior, and build a measurable twin. Each capture is compared against the previous one and against design, so progress, deviations and quantities show up in your portal as a time-stamped, RERA-ready record.

It overlays your drawings or model onto captured reality so you can see where what's built diverges from what was designed — catching deviations early, before they get covered up, and turning them into trackable field notes.

Yes. We deliver immersive interior walkthroughs pinned to your floor plans and survey-grade exterior models. Walk every floor from a browser, jump between capture dates at the same spot, and document work before it gets covered up.

Time travel lets you stand at the same point on a floor plan and flip between capture dates — the same room at slab, framing, services and finish stages — a visual audit trail of what was built, when, and what got covered up.

Yes. Our captures produce time-stamped, evidence-linked progress records structured for periodic reporting, so RERA and owner updates are backed by verifiable site data instead of a scramble of photos.

For linear infrastructure we deliver corridor mapping, DPR-stage topographic inputs, earthwork cut-and-fill volumes and periodic progress capture — aligned to the monthly survey cadence agencies increasingly mandate, with chainage-referenced deliverables.

A DPR (Detailed Project Report) survey provides the topographic and terrain inputs needed to plan a project — contours, levels and site context — captured quickly and to survey-grade accuracy so design can begin on reliable ground truth.

We provide independent, geo-tagged, survey-backed evidence of physical progress tied to disbursement milestones — so draws match ground truth, not just the borrower's claims. Useful for lender's independent engineer support and portfolio monitoring.

Land and contour surveys, plot and layout visualisation, boundary and encroachment checks against records, and sales-ready aerial views and site tours — with survey-grade accuracy for developers, plotting ventures and land owners.

Yes — alongside the survey-grade data we produce cinematic aerial views and shareable site tours that developers use for sales and investor updates, all from the same capture.

A measurable 3D virtual replica of a site, built from capture data and updated as the site changes. Teams use it to monitor progress, calculate volumes, detect deviations from design and keep a permanent record of what was built, when.

BIM is the design-intent model of what should be built; a digital twin is the as-built mirror of what actually exists on site, captured over time. The two are complementary — we can compare your BIM against captured reality.

Yes — through 2027 we're rolling out image processing and AI that reads progress directly from captures: exterior earthwork and structure detection, interior component recognition, automated deviation detection, and BIM-vs-reality comparison, with human-in-the-loop review.

Delta Astra offers OpenSpace-style interior walkthroughs, floor-plan pinning and time travel — and adds survey-grade exterior mapping, CAD overlays and measurement toolsets in one platform, with India-first support and RERA-friendly reporting.

Cost depends on site area, terrain, deliverables and revisit cadence. Small parcels are economical on a per-acre basis; large corridor, mining or portfolio programs are priced per project. We offer a paid pilot so you can evaluate real deliverables first.

Most deliverables land within days of capture. The exact turnaround depends on site size and the deliverable set, and is agreed up front so reporting stays predictable.

Book a paid pilot. We capture your site, build the twin and hand back working deliverables so you can evaluate the platform on your own project before committing to a program. Email contact@deltaastra.com.
