When does a pharma plant need its P&IDs updated and a HAZOP redone?
Pharma plants call us for six reasons, and four of them are a change to the plant rather than a date on a calendar.

Which rules make accurate P&IDs and a current HAZOP necessary in India?
No Indian rule sets a fixed P&ID update interval, but three instruments turn an outdated drawing set into an audit finding.
| Instrument and clause | What it means for your drawings and HAZOP |
|---|---|
| MSIHC Rules 1989 · Rule 10(4), 10(6) | An independent safety audit by an expert not associated with the plant, repeated once a year with a copy to the authority within 30 days. |
| MSIHC Rules 1989 · Rule 11(1) | A further safety report at least 90 days before any modification that could materially change the earlier report. |
| IS 15656:2006 · Cl 5.1.2.3, 8(g) | HAZOP takes detailed P&I drawings as its input, and risk analysis is redone after a major change in plant configuration. |
| Revised Schedule M · CDSCO directive | State inspections began on 7 November 2025; small and mid-size units had until 1 January 2026 under the extension. |

What does a FieldSure engagement cover in a pharma plant?
Every process and utility P&ID you choose is checked line by line against the plant, corrected, and then taken through HAZOP.

- Process P&IDs: reactors, centrifuges, dryers, solvent recovery
- Utility P&IDs: purified water, WFI, clean steam, HVAC, nitrogen
- Field walkdown with redline markup
- LiDAR scan in congested areas
- Discrepancy log: every difference found
- Redlines built into your native CAD files
- HAZOP with an independent chairman
- Action register your team can close
Send us your drawing list and we will price exactly what you have.
How much does a HAZOP and P&ID updation cost for a pharma plant?
A HAZOP and P&ID updation for a pharma plant is priced per verified drawing, with the HAZOP priced on the drawings and nodes it reviews, so the number of P&IDs in scope sets most of the cost. Share your count below and our engineer sends a validated price range and proposal.
| Part of the work | How it is priced | What moves the price |
|---|---|---|
| Field-verified P&ID | Per verified drawing: walkdown, redline, CAD update and QA | Condition of your existing drawings, access and gowning, CAD format |
| HAZOP on verified drawings | Per P&ID reviewed, set by nodes and study days | Process complexity, number of nodes, chairman days |
| LiDAR scan (where needed) | Per area scanned | Congestion, height and number of scan positions |

Your price range and proposal reach you by email once our engineer has validated your inputs. No obligation, and five drawings checked free on site if you want proof first.
How is a FieldSure engagement run, and how long does it take?
Four stages run in sequence, from the first walkdown to a signed HAZOP report and an action register your plant can close.

Every plant change updated on the drawings.Do not run a HAZOP on drawings nobody has walked. A HAZOP reviews what is on the P&ID. If a bypass, a hose connection or a solvent line exists only in the plant, the study cannot see it and the risk goes unrecorded.
Which scanners and software does VB use for P&ID and as-built work?
VB captures plants with the Leica RTC360 laser scanner, registers the scans in Leica Cyclone REGISTER 360 PLUS and Autodesk ReCap Pro, and draws P&IDs and 3D models in AutoCAD Plant 3D and Autodesk Revit. Your drawings come back in the format your engineers already open every day.
| Stage | Tools we work in | What you receive |
|---|---|---|
| Capture | Leica RTC360 laser scanner · FARO Focus and Trimble X7 where your site specifies them · field walkdown with redline markup | Coloured 3D scans of every area in scope, with photos |
| Register | Leica Cyclone REGISTER 360 PLUS · Autodesk ReCap Pro | One registered point cloud (E57, RCP or RCS) |
| Draw P&IDs | AutoCAD Plant 3D P&ID · AutoCAD P&ID · AVEVA and Hexagon Smart P&ID formats on request | Verified P&IDs in DWG and PDF, with the tag database |
| Model | AutoCAD Plant 3D · Autodesk Revit | 3D plant model, isometrics and general arrangement drawings |
| Review | Autodesk Navisworks | One federated model your team can walk through and mark up (NWD) |

What does a FieldSure engagement on an API plant look like?
A typical API plant engagement starts with a walkdown of the drawings in scope, logs every difference between paper and pipe, and ends with a HAZOP run on corrected drawings and an action register the site can close.
On a pharma site the walkdown usually turns up the same things: bypasses added during a campaign, hose connections made permanent, a pump replaced with a new tag, a solvent line rerouted for a new block. Each one is redlined, logged and built into your CAD files before the HAZOP team opens the first node. The study then reviews the plant you operate, and every action lands on a drawing your auditor can check.

Who verifies the drawings, who chairs the HAZOP and who signs?
Three roles, each a named engineer listed in your proposal with CV, so your auditor knows exactly who stands behind the report.

How much does a HAZOP study cost?
A HAZOP study is priced on the P&IDs and nodes it reviews and the number of study days. Share your P&ID count in the price form and our engineer sends a validated range and proposal.
What is the cost of P&ID updation per drawing in India?
P&ID updation is priced per verified drawing and covers the walkdown, redline, CAD correction and QA. The final figure depends on drawing condition and access, so we send it as a written proposal.
Who should update the P&IDs and run the HAZOP?
One team should own both, because the HAZOP is only as good as the drawings it reviews. FieldSure verifies the drawings first and then runs the study on them.
Can a HAZOP be done on outdated P&IDs?
It can be run, but it reviews the plant on paper, not the plant you operate. IS 15656:2006 lists detailed P&I drawings as the HAZOP input.
How long does a HAZOP take for a pharma plant?
Workshop days depend on node count, and the full FieldSure sequence depends on how many drawings are in scope. Your proposal states both.
What documents are required for a HAZOP study?
P&IDs first, then process descriptions, material safety data, cause and effect charts and operating procedures.
Is P&ID updation the same as redrawing?
No. Redrawing copies the old drawing into new CAD. Updation checks every line against the plant and corrects what has changed.
Do we need a LiDAR scan?
Only where the plant is congested or access is limited. Most pharma utility areas can be verified by walkdown.
Who is responsible for keeping as-built drawings current?
The plant owner. Contractors hand over drawings, but every later change has to be recorded by the site.
Can AI read our P&IDs instead?
AI can digitise a drawing. It cannot tell you whether the line still exists in the plant. That needs someone on site.
