Accuracy Above All
Construction errors aren't UX problems — they're structural failures. Every feature we build is held to centimeter-level accuracy as a non-negotiable baseline.
OUR STORY — BUILT IN BHARAT
We build the bridge
between design
and reality.
DeltaARBIM is an AR-powered BIM intelligence platform built by Shivlam — a team of engineers who spent a decade in corporate construction tech before deciding to build something better.
Our mission
Eliminating the gap between BIM design and real-world construction.
Construction projects lose billions every year to rework — the simple, catastrophic result of building something that doesn't match the design. A beam in the wrong place. A pipe that clashes with a duct. A wall 8 centimeters off.
DeltaARBIM exists to make those errors visible before they become concrete. Our platform puts a live 3D BIM model — every wall, every pipe, every structural layer — directly over the physical site through your device's camera. If it's wrong, you'll see it before a single dollar is wasted.
“Construction has always had the data. We just finally put it in the right place — on the site, in the hands of the person holding the trowel.”
— Shivlam Engineering Team, DeltaARBIM
30%
Average Rework Cost Reduction
Sites using AR BIM overlays report up to 30% reduction in costly construction rework through early clash detection.
±2cm
Spatial Accuracy
LiDAR + computer vision anchoring locks BIM models to real-world coordinates with centimeter-level precision.
60fps
Real-Time AR Render Rate
Full BIM geometry renders at 60 frames per second — no lag, no stuttering, even for complex multi-storey models.
IFC
Open BIM Standard Support
Accepts IFC, RVT, NWD and all major BIM formats. No proprietary lock-in. Works with Revit, Navisworks, and ArchiCAD.
Our journey
From corporate engineering
to product innovation.
DeltaARBIM didn't begin in a startup garage. It began inside large-scale construction technology teams, watching the same problems repeat project after project. Here's how we got here.
- 2014
Corporate Engineering Roots
Our founding team began careers in enterprise software and construction technology — working on large-scale platform architecture for Tier-1 construction companies across India and internationally.
FOUNDATION - 2018
Identifying the Problem
After years of building software for construction clients, the pattern became clear — BIM models existed in laptops while workers built from printed drawings. The gap between design and site was costing everyone.
INSIGHT - 2022
Shivlam — A New Chapter
After 10+ years in corporate tech, the team founded Shivlam — a focused product studio built around one idea: technology should solve real problems for real workers, not just look good in demos.
COMPANY FOUNDED - 2023
DeltaARBIM — Concept to Prototype
The first working prototype of DeltaARBIM demonstrated live BIM overlay on a real construction floor using LiDAR-anchored spatial tracking. The results validated everything the team had suspected for years.
PRODUCT BIRTH - 2026
Active Development — Coming Soon
DeltaARBIM is in active development with early access partners from the construction and MEP contracting space. We're building toward a public launch that brings enterprise-grade BIM AR to every job site in Bharat and beyond.
IN DEVELOPMENT
What we stand for
Principles that drive
every line of code.
We're a small team with strong opinions about what good software looks like — especially when lives and livelihoods depend on it working correctly.
Field-First Design
We design for dusty hands, bright sun, and noisy job sites — not for conference room demos. If it doesn't work on the floor, it doesn't ship.
Open Standards
We built on IFC and open BIM standards from day one. No proprietary lock-in. Your model, your data — accessible from any tool in your existing workflow.
Lean and Deliberate
We run a team of 10+. Not because we can't scale, but because we believe the best software comes from people who take personal ownership of every decision.
Built for Bharat
India's construction market is one of the world's largest. We build for that scale, that complexity, and those conditions first — then take it everywhere else.
Ship Real, Not Demo
Every product we deliver is a production deployment. No half-finished features, no perpetual betas. 50+ projects across our portfolio — every single one live.
The company behind DeltaARBIM
