Regulatory compliance is often treated as something to address near the end of a manufacturing plant project, when licences are being applied for or inspections are approaching. That approach can create avoidable problems.
Compliance requirements can influence the site selected, plant layout, utilities, equipment, testing facilities, safety systems and operating procedures. India’s National Single Window System itself distinguishes between pre-establishment and pre-operation approvals, showing that regulatory requirements can arise at different points in the project lifecycle.
For a new manufacturing plant, the better approach to regulatory compliance for plant setup is to review requirements progressively, starting during feasibility and continuing through commissioning and commercial operations.
Why Regulatory Compliance Should Start Before Construction
The first question should not be, “Which licence do we need before production?”
It should be:
“What regulatory requirements could change our project design or investment decisions?”
This distinction matters because some requirements affect the physical plant.
For example, GMP considerations can involve premises, equipment, facilities and quality systems. CDSCO’s GMP inspection checklist covers areas including suitable premises and equipment, manufacturing-site controls and lifecycle application of GMP.
Similarly, BIS certification can require appropriate manufacturing infrastructure, process controls, quality control and testing capabilities. BIS assesses these capabilities at the manufacturing premises.
Therefore, compliance is not only a documentation exercise. It can become an engineering input.
The 7 Stages When Compliance Should Be Reviewed
1. During Feasibility and Project Concept
This should be the first structured regulatory review.
Before committing substantial capital, the project team should identify which requirements may apply to the proposed product, process and facility.
Review:
- Product-specific regulations and standards
- GMP requirements, where applicable
- BIS standards and Quality Control Orders
- Environmental requirements
- Factory and building-related approvals
- Fire and occupational safety requirements
- Hazardous-material requirements
- Product testing and laboratory requirements
- Export-market regulations, where relevant
The output should be a regulatory applicability matrix showing the requirement, responsible authority, project stage, documents needed and likely impact on design or schedule.
This is also where companies should distinguish between requirements that affect whether the project can proceed and those that affect how the plant must be designed.
2. During Site Selection
A site may appear attractive because of land cost, connectivity, utilities or proximity to customers. That does not automatically make it a suitable manufacturing location.
Before finalizing the site, review:
- Applicable land-use and industrial requirements
- Environmental sensitivity
- Water availability and discharge arrangements
- Power availability
- Waste-management requirements
- Fire access and emergency arrangements
- Hazardous-material storage considerations
- Local factory and building requirements
- Future expansion constraints
The National Single Window System provides an approval-identification mechanism based on business requirements, but it also cautions that its results are guidance and that applicants should check relevant government portals for other approvals.
Site selection should therefore include a regulatory suitability check, not just a commercial or engineering assessment.
3. Before the Plant Layout Is Frozen
This is one of the most important compliance review points.
Once the basic layout is finalized, changing the relationship between production areas, warehouses, laboratories, utilities and personnel movement becomes progressively more difficult.
At this stage, review:
- Material and personnel flows
- Production-area segregation
- Storage arrangements
- Waste movement
- Utility locations
- HVAC zoning
- Drainage
- Fire protection
- Emergency access
- Quality-control and testing areas
- Equipment positioning
For pharmaceutical facilities, CDSCO’s GMP inspection framework specifically considers premises, equipment and facilities as part of GMP assessment.
The objective is not simply to obtain an approval later. It is to make sure the proposed facility can physically support the required compliance conditions.
4. During Detailed Engineering and Equipment Procurement
A compliance review should continue after the layout is approved.
This is where regulatory requirements should be translated into equipment specifications and engineering documents.
Questions may include:
- Does the equipment provide the required process controls?
- Can it be cleaned, inspected and maintained appropriately?
- Are required measurements possible?
- Can critical instruments be calibrated?
- Are materials of construction suitable?
- Does the equipment arrangement support required segregation?
- Is adequate testing capability included?
- Are utilities sized and designed for the applicable requirements?
BIS provides a useful example of why this needs to happen before procurement. Its licensing process requires manufacturers to identify the applicable Indian Standard and document the required manufacturing infrastructure, process controls, quality-control and testing capabilities.
A late discovery that a selected machine, laboratory or utility system cannot support the applicable requirement can mean redesign, replacement or additional investment.
5. During Construction and Installation
Construction should not be treated as a compliance-free period.
Periodic reviews should compare actual construction against approved drawings, specifications and regulatory requirements.
Depending on the industry, this can include:
- Civil construction
- Room dimensions and finishes
- Drainage
- HVAC installation
- Utility piping
- Electrical systems
- Fire protection
- Equipment foundations
- Storage areas
- Hazardous-area controls
- Waste-handling systems
This stage is particularly important because some defects become expensive to correct after walls, ceilings, floors, piping or equipment installations are completed.
A practical approach is to define construction inspection hold points for systems where later verification would require significant dismantling or rework.
6. During Commissioning and Pre-Operation
At commissioning, the question changes from:
“Have we designed the facility correctly?”
to:
“Can we demonstrate that the facility operates as required?”
The compliance review should now cover:
- Equipment qualification
- Utility qualification
- Calibration
- Testing
- Process validation, where applicable
- Cleaning and sanitation controls
- SOPs
- Training
- Quality documentation
- Emergency systems
- Required inspections
- Operating licences and permissions
Environmental compliance is one example of why this stage matters. Current pollution-control rules provide for Consent to Operate once an industrial unit has been established with the requisite pollution-control system and is ready to operate, with compliance information relating to applicable Consent to Establish and environmental-clearance conditions.
This means the project should not wait until commissioning to discover whether the installed systems actually satisfy earlier conditions.
7. After Commercial Production Starts
Regulatory compliance does not end when the first production batch is released.
Plants need a mechanism to manage:
- Regulatory changes
- Internal compliance audits
- Corrective actions
- Licence renewals
- Process changes
- Equipment modifications
- Product additions
- Capacity expansion
- Supplier changes
- Updated procedures and training
BIS, for example, states that surveillance after certification can include checking whether the manufacturer continues to maintain manufacturing infrastructure, process controls, quality-control and testing capabilities.
For a growing manufacturing operation, ongoing compliance should therefore be connected to the plant’s change-control process, rather than managed as a one-time project activity.
Four Regulatory Review Freeze Points
A practical plant project can establish four formal compliance checkpoints.
Freeze Point 1: Before Site Finalization
Confirm that major regulatory constraints have been identified before the land or facility decision becomes difficult to reverse.
Freeze Point 2: Before Design Freeze
Confirm that applicable requirements have been translated into the process flow, layout, utilities, safety systems and facility design.
Freeze Point 3: Before Critical Procurement
Confirm that equipment, testing systems and utility specifications support the applicable regulatory requirements before purchase orders are finalized.
Freeze Point 4: Before Commercial Production
Confirm that required inspections, licences, qualifications, testing, documentation and operating controls are complete before routine production begins.
These checkpoints are more useful than simply scheduling one “compliance review” at the end of the project.

What Happens When Compliance Is Reviewed Too Late?
Late compliance review does not always mean that a project will fail. The bigger risk is avoidable rework.
A project may have to deal with:
- Plant-layout modifications
- Equipment relocation
- Utility redesign
- Additional testing infrastructure
- Civil rework
- Documentation gaps
- Repeated inspections
- Procurement changes
- Commissioning delays
- Additional project costs
Consider a pharmaceutical plant where GMP review begins after the HVAC system, equipment positions and room layout have already been finalized. If the review identifies a segregation or airflow issue, the problem is no longer simply a compliance-documentation issue. It has become an engineering problem.
That is why compliance should be built into project decisions before those decisions become expensive to change.
A Practical Regulatory Compliance Review Checklist
Before moving from one major project stage to the next, ask:
- Have all applicable regulations and standards been identified?
- Has the responsible authority for each requirement been confirmed?
- Are pre-establishment and pre-operation approvals separated?
- Has the site been checked for regulatory suitability?
- Are compliance requirements reflected in the plant layout?
- Have utilities and equipment been reviewed against those requirements?
- Are required testing and quality-control facilities included?
- Have construction inspections been defined?
- Are qualification, validation and documentation requirements planned?
- Are approval dependencies reflected in the project schedule?
- Has a responsible person been assigned to each compliance action?
- Is there a process for managing regulatory changes after commissioning?
The exact approval list will vary by state, industry, product, process and project characteristics. Government approval portals should therefore be used to verify the requirements applicable to the specific project rather than relying on a generic checklist.
How IMARC Engineering Can Help
IMARC Engineering can support manufacturers in integrating regulatory requirements into plant-development decisions rather than treating compliance as a final-stage activity. Its support can include regulatory requirement mapping, compliance gap identification, coordination of applicable approvals, review of plant layouts and project documentation, and integration of compliance considerations with engineering, procurement and commissioning activities. This approach helps project teams identify potential regulatory constraints earlier, coordinate technical requirements across disciplines and reduce the risk of discovering major compliance-related changes after construction or equipment procurement.
Conclusion
Regulatory compliance should be reviewed throughout the plant setup lifecycle, beginning at feasibility rather than waiting until commissioning. The most valuable reviews occur before site selection, design freeze, critical procurement and commercial production because these are the points where compliance requirements can still influence project decisions without extensive rework. For manufacturers, the objective is not simply to collect approvals. It is to build a facility whose site, layout, equipment, utilities, systems and operating controls are capable of meeting the requirements that apply to the business.
