RBVBS turns a pre-engineered building into a live 3D record — capture site progress, validate every transition, and publish the daily report. Every assembly, every day.
Foundations across the whole site, then frame by frame from the end wall: columns, rafters, alignment, QC, braced to the next frame, then girts & purlins. The Gantt and calendar move with the steel.
Steel, crews and cranes each have a comfortable time to fabricate, dispatch, erect and sign off. RBVBS weighs every preference against the whole programme — and converges on one agreed schedule, tonnage balance and handover date.
PEB members ship in non-standard sizes and weights. RBVBS nests each load for full decks without overload, routes it past height & turning limits across India, and drops it exactly where the next bay is going up — datewise and baywise.
RBVBS is the one group that links design to nesting in real time. The instant members are optimised, the material plan builds itself — every plate auto-nested to the tightest layout, wastage driven down, and off-cuts returned to stock and reused. The designer knows the saving the moment the drawing is done.
Each optimised nest becomes a real CNC toolpath. RBVBS plays the cut back live — every pierce, every kerf, every rapid — so the shop sees exactly what the machine will do before the torch ever fires.
RBVBS models every connection as a graph G(V,E) — vertices are bolted junctions, edges are the members they join. The moment a frame is designed, every junction’s bolt diameter, length, grade, washers, nuts and counts are checked against its grid before erection — design to detailing to purchase to site to dispatch, in one closed loop.
Pre-engineered buildings are erected layer by layer: footings, columns, rafters, bracing, girts, sheeting. RBVBS holds the whole structure as a live model, records every milestone from the field, and turns the day's work into a dated, defensible progress report.
Slide through time and watch frames, braces and girts appear exactly as they were erected on site. Any day, any bay, any assembly — rendered, not described.
Tap an assembly, set its milestone — received, erected, QC — from any device on site. The daily progress report assembles from the events as they land.
Every state change is checked against the erection logic. No column before its footing, no sheeting before its purlins. The model refuses what the site can't do.
Bolt counts, steel weights and bay totals roll up live and tally against the geometry — not a spreadsheet that drifted three revisions ago.
Field crews mark milestones straight on the model — received, erected, bolted, QC — from a phone or tablet at the frame.
Each transition is checked against the build sequence before it's accepted. Out-of-order events are caught at the point of entry.
The dated DPR — model, quantities, status by layer — is published to every stakeholder. One source of truth, stamped by day.
Every right angle a PEB depends on traces back to the rope stretchers. This lab holds the ancient surveying constructions, the SNGT trigonometry parser and the rope-and-bush algebra behind RBVBS — each one a live, draggable instrument, rebuilt on the RBVBS design system.
46 theorems from Walker & Millar (1954), each rebuilt as a live, auto-verified demonstration.
