THE IMMERCIAL METHOD™ — COMPANY IMPLEMENTATION GUIDE

Updated 19 August 2026

Controlled use of Immercial methods and resources within an organisation.

View Governance

This guide is intended for directors, commercial managers and organisations using authorised Immercial Method™ resources internally or in connection with an Immercial engagement.

The purpose is not to require organisations to replace their existing commercial systems or operating procedures.

It is to provide a clear framework for using Immercial methods, templates, benchmark information and associated resources in a controlled, consistent and appropriately governed way.

Use of IMME intellectual property remains subject to the current IMME Licence™, together with any engagement-specific requirements agreed with Immercial.

1. Nominate an Internal IMME Contact

Where an organisation makes regular use of authorised IMME resources, it is helpful to nominate a responsible internal contact.

This may be a:

  • director
  • commercial manager
  • senior QS
  • document controller
  • other appropriate project lead

The role may include:

  • maintaining awareness of current versions
  • coordinating authorised internal use
  • acting as a point of contact with Immercial
  • communicating relevant updates internally
  • supporting appropriate document and access controls

This does not create a separate accreditation or professional status.

It simply provides a clear point of responsibility within the organisation.

2. Use Current Controlled Information

Teams should work from current information obtained through an official Immercial-controlled source.

This may include:

  • official Immercial websites
  • the IMME Portal
  • authorised Immercial systems
  • controlled client-delivery channels
  • material issued directly by Immercial

Superseded or unofficial copies should not be relied upon as current Immercial-controlled information.

Where internal document management systems are used, organisations should maintain clear version status and avoid uncontrolled duplication.

3. Preserve Source, Version & Identity

Official IMME resources may include:

  • document or template IDs
  • version numbers
  • watermarks
  • copyright or licence information
  • Immercial Method™ branding

Where present, these identifiers should remain visible.

They help users understand:

  • the source of the information
  • whether it is current
  • whether it is an official Immercial issue
  • the status of any adapted version

Modified material must not be represented as an official Immercial-controlled issue unless expressly approved and issued as such by Immercial.

4. Apply the Method Appropriately

The Immercial Method™ provides a structured MEP commercial methodology across relevant stages of a project lifecycle.

Organisations should apply the relevant stages in a logical sequence appropriate to:

  • the project
  • the procurement route
  • the scope of engagement
  • the commercial issue being managed
  • the information available

The Method is intended to improve continuity, traceability and commercial control.

It does not remove the need for project-specific judgement or require every project to follow an identical administrative sequence.

5. Use Templates as Controlled Tools

IMME templates provide structured implementations of parts of the Method.

Where their use is appropriate, organisations should ensure that:

  • the correct template or record is selected
  • the current version is used
  • inputs and assumptions are clear
  • changes are traceable
  • adapted versions are identified appropriately
  • outputs remain subject to professional review

Templates support the commercial process.

They do not replace the commercial reasoning behind it.

6. Use Benchmarks & Rate Information in Context

Immercial benchmark information, QSOR and other commercial reference information are intended to support analysis and specialist review.

They should not be treated as automatic project answers.

When using such information, organisations should consider factors including:

  • project type
  • scale
  • location
  • date
  • programme
  • scope
  • procurement context
  • specification
  • market conditions

Any material deviation from the relevant basis should be understood and recorded where appropriate.

Evidence supports judgement; it does not replace it.

7. Maintain Appropriate Internal Quality Controls

Where IMME resources are used internally, organisations should apply proportionate quality controls.

These may include:

  • checking version status
  • reviewing key assumptions
  • checking completeness
  • confirming the correct project/context information has been used
  • ensuring adaptations are clearly identified
  • retaining appropriate commercial records
  • obtaining senior or specialist review where required

The level of review should reflect the importance, complexity and risk of the commercial decision.

8. Respect Licence & Intellectual Property Requirements

Use of IMME intellectual property is governed by the current IMME Licence™ and any relevant written agreement with Immercial.

Unless expressly authorised, controlled IMME material must not be:

  • resold
  • publicly republished
  • redistributed to third parties
  • re-hosted as an independent resource
  • embedded into external commercial products or platforms
  • represented as third-party intellectual property
  • used to train or develop external AI systems

Internal use and adaptation remain subject to the terms of the current IMME Licence™.

9. Use IMME AI Appropriately

IMME AI is a controlled, domain-specific support capability within the Immercial ecosystem.

Where authorised access is available, it may assist with:

  • retrieving relevant Immercial knowledge
  • locating appropriate methods or templates
  • structuring commercial information
  • interrogating benchmark or rate information
  • supporting specialist review

AI-supported information must still be considered against the particular project and engagement.

It does not replace:

  • contractual interpretation
  • evidence validation
  • commercial recommendation
  • professional judgement
  • specialist responsibility

Immercial intellectual property should not be uploaded to or used to train external general-purpose AI systems except where expressly authorised.

10. Manage Changes & Improvements Through Controlled Feedback

Organisations using Immercial resources may provide feedback regarding:

  • usability
  • identified gaps
  • project experience
  • terminology
  • template improvements
  • benchmark or system observations

Feedback does not automatically change the Method or an official resource.

Immercial reviews proposed changes and determines whether they should be incorporated following appropriate validation and version control.

This supports continual improvement without compromising governance.

11. Support Internal Understanding

Where teams use the Method or associated resources, organisations should ensure relevant staff understand:

  • what the Method is intended to achieve
  • which resources are applicable
  • how current versions are identified
  • how adaptations should be treated
  • the limitations of benchmark and AI-supported information
  • their licence and confidentiality responsibilities

The IMME Academy™ may provide additional structured learning and professional-development support where appropriate.

12. Maintain Clear Professional Responsibility

Use of the Immercial Method™, templates, benchmarks, QSOR, commercial systems or IMME AI does not transfer professional responsibility to the tool or system.

Organisations remain responsible for the commercial work they undertake and for ensuring that appropriate competence, review and judgement are applied.

Where Immercial is professionally engaged, Immercial’s responsibilities are governed by the relevant scope of service and engagement terms.

Practical Company Implementation

A proportionate internal approach may include:

1. Nominate a responsible contact
Identify who will manage authorised IMME use internally.

2. Maintain a controlled source
Ensure teams can identify the current authorised version of relevant resources.

3. Define where IMME resources are used
Apply them where they add value rather than imposing unnecessary duplication.

4. Retain version and source information
Keep controlled identifiers and clearly mark adaptations.

5. Apply appropriate review
Use senior or specialist review proportionate to commercial risk.

6. Communicate material updates
Ensure relevant teams understand significant changes affecting their work.

The Principle

Successful implementation is not measured by how many IMME documents an organisation uses.

It is measured by whether the relevant commercial information is:

clear, controlled, traceable, appropriately evidenced and professionally reviewed.

The Immercial Method™ provides structure.

Professional judgement determines how that structure is applied.
