An illustrative worked example: how a Tier-1 high-rise builder would put a single Green / Amber / Red control layer over its existing stack — turning every drawing, SWMS, hold point and delivery into a verified, scan-to-act decision at the point of work.
The scenario builder is an Australian Tier-1 high-rise builder delivering apartment and high-rise projects. The scenario is set against a demanding Tier-1 benchmark: jumpform-core towers, crane-dependent logistics, and dozens of subcontractors working concurrent fronts on a live, vertical site — the kind of program where a single superseded sheet or an expired high-risk ticket can stop a pour, a lift or an inspection. It is exactly the environment where a control layer either earns its place every morning or it does not.
The site team already runs the job — across a project management platform, a compliance system, spreadsheets and document folders. Each tool does its part well. What none of them does is answer the Site Manager's real 6am question in one place: what's ready, what's late, what's at risk, and what requires action today? The information exists, but it is scattered across four systems and a stack of folders, so the answer has to be assembled by hand every morning before the crews start. The ask was specific and pragmatic: connect eight systems — Safety, QA/ITP, Programme, Procurement, Drawing Control, Site Manager Dashboard, Subcontractor Management, and Defect & Handover — into one source of truth, without ripping anything out.
Obras Onsite is not a replacement for the builder's platforms — it is the operational control layer that sits above them. It takes every controlled item across the eight systems and resolves it to a single, honest verdict: Green (current, verified, cleared to proceed), Amber (a risk or action with an owner), or Red (blocked — do not build). Two differentiators run through all eight systems. First, QR verification: every drawing, SWMS, VOC, permit and register carries a QR code, so a crew can scan at the point of work and follow a simple loop — Scan, Verify, Control, Act. No one builds off a superseded sheet or an expired SWMS, because the item itself tells them its status. Second, the Green/Amber/Red Control Room: the Site Manager opens one board and, in roughly ten seconds, knows whether each work front can start — with every Red carrying a named owner and a clear-by time, and CM and Builder lenses rolling the same truth up the chain.
The scenario is designed to prove the control layer with concrete, repeatable moments rather than abstract dashboards. A drawing scanned on site resolves to 'Red — SUPERSEDED, do not use', with the current revision one tap away, so rework is avoided before it starts. A subcontractor's expired high-risk VOC shows Red on the compliance board, so the operator is stood off the plant before work begins rather than discovered at audit. And the Site Manager's Control Room rolls programme, QA, compliance, drawings and defects into a single daily Green/Amber/Red verdict per work front. These are demonstrations of capability during the scenario; the outcome figures on this page are illustrative design targets, to be replaced with measured results as the scenario runs.
For the builder, the value is operational: fewer surprises, less rework from superseded information, compliance exposure closed before work starts, and a defensible, QR-verified evidence trail for the principal, the certifier and the insurer — proven by scan at the point of work, not assembled the night before an audit. For Obras Onsite, the scenario is the flagship reference: a real Tier-1 builder running one operating system across eight connected systems, on top of the stack they already own. That is the proof that de-risks the next enterprise and per-project builder conversations — a working scenario on a live high-rise, not a slide deck.
| System | What Obras Onsite delivers | Green / Amber / Red logic |
|---|---|---|
| 1. Safety | Compliance OS with SWMS / VOC / permit libraries, every item QR-tagged for point-of-work verification | Green = current & signed · Amber = expiring · Red = expired/unsigned, work blocked |
| 2. QA / ITP | QA / ITP Control (High-Rise OS) with hold points and NCR management | Green = released · Amber = witness/inspection pending · Red = hold point open |
| 3. Programme | Programme Control tracking the critical path with owned recovery actions | Green = on programme · Amber = slipping · Red = behind, recovery owned |
| 4. Procurement | Procurement Control over long-lead items and float against the programme | Green = ordered · Amber = due soon · Red = negative float, build stops |
| 5. Drawing Control | Document & RFI Control OS — Document Control Register, RFI Register and RFI Tracker, each sheet QR-verifiable on site | Green = current approved · Amber = under review · Red = superseded, do not use |
| 6. Site Manager Dashboard | Site Management Dashboards plus the Control Room with SM / CM / Builder lenses on one truth | One verdict per work front: what requires action today, with owners and clear-by times |
| 7. Subcontractor | Induction & Subcontractor Approval (Compliance OS) covering induction, insurance and prequalification | Green = inducted, insured & prequalified · Red = not approved, not on site |
| 8. Defect & Handover | Defect Management plus finishes handover tracking through to close-out | Green = closed · Amber = open and in time · Red = overdue or buried |

Book a Obras Onsite walkthrough and we'll map your eight systems — Safety, QA/ITP, Programme, Procurement, Drawing Control, Site Dashboard, Subcontractor and Defect & Handover — into one QR-verified Green/Amber/Red Control Room that sits on top of the stack you already use. Built by construction leaders, not consultants.
