Why the Immercial Method™ Exists
The MEP sector has long faced challenges:
-
inconsistent templates across companies
-
variable quality of commercial outputs
-
unclear assumptions
-
gaps between design, cost and delivery
-
fragmented processes
-
different QSs learning different methods in every business
The Immercial Method™ solves this.
It provides a single, coherent and modern framework that raises the standard of MEP commercial practice across the entire industry while remaining open, accessible and free.
Inconsistent Templates
Different structures across companies create confusion.
Variable Standards
Commercial outputs change dramatically from QS to QS.
Fragmented Processes
No unified flow from enquiry to CVR.
Lack of Commercial Clarity
Assumptions, quantities and risks often go undocumented.
The IMME Workflow Sequence
The Immercial Method™ follows a clear, 19-step, logical workflow that mirrors the real commercial lifecycle of MEP projects.
Each IMME template is designed to support a specific stage — ensuring clarity, full coverage of commercial responsibilities, and complete traceability from enquiry through to final CVR.
IMME Portal — the secret source for all MEP rates, benchmarks, cost plans, and alignment.
IMME Enquiry - Formal issue of tender instructions and commercial requirements.
IMME Clarifications - Formal clarification log to align scope, risks and assumptions.
IMME Take-Off - Measured quantities and scope breakdown of MEP systems.
IMME Cost Plan - Early-stage cost intelligence aligned to design development.
IMME Pricing Schedule - Controlled pricing structure for contractor tender submissions.
IMME Tender Query - Formal commercial and scope-based questions issued during tender.
IMME Tender Return - Contractor’s formal tender submission using IMME formats.
IMME Levelling - Like-for-like comparison of tender submissions.
IMME Recommendation - Commercial advice on preferred tenderer and award strategy.
IMME Contract-Subcontract Agreement - Commercial agreement governing contractual obligations.
IMME Contract Review - Structured review of contract terms, conditions and obligations.
IMME Interface Responsibility Matrix - Clear definition of scope boundaries and responsibilities.
IMME Scope of Works - Written description of the works to be priced and delivered.
IMME Fee & Programme - Alignment of commercial commitments with programme dates.
IMME Notification of Delay & Early Warning - Formal contractual notices relating to time and delay impacts.
IMME Variation Instruction - Clear instruction for changes to scope or works.
IMME Substantiation - Evidence supporting valuation of changes and claims.
IMME Application, VO, Certification & Cashflow - Management of valuations, variations and project cashflow.
IMME Cost Value Reconciliation - Reconciliation of cost versus value to calculate project margin.
Governance — Freedom with Structure
The Immercial Method™ is free to use, but protected by a light, modern governance framework that keeps the standard consistent worldwide.
Governance ensures clarity, version control, and proper use of IMME IP — without restricting users or adding bureaucracy.
It’s what allows the Method to remain trusted, unified and future-proof.
Below are the core governance principles every user and company must follow.
Version Governance
Immercial maintains strict version control of all IMME templates, benchmarks and definitions.
Users must always download the latest version directly from the Immercial website and avoid storing or circulating outdated copies.
This ensures that all QSs worldwide are aligned and working to the same standard.
Brand & Identity Governance
All IMME documents contain essential identifiers:
-
Template ID
-
Version number
-
Watermark
-
Footer licence text
-
Immercial Method™ branding
These elements must remain fully visible and unchanged.
This preserves authenticity and ensures immediate recognisability.
Process Governance
The IMME workflow sequence must be followed in the correct commercial lifecycle order.
Skipping stages or reordering the process undermines clarity and creates commercial risk.
The sequence exists to ensure full coverage and transparent traceability from enquiry to CVR.
Content Governance
Users may adapt IMME templates internally, but they must not:
-
redefine IMME assumptions
-
change IMME terminology
-
rewrite core definitions
-
alter commercial logic
Modifications must never be presented as official IMME standards.
This protects the integrity of the Method across organisations.
Access Governance
IMME IP must only be accessed from the official Immercial website.
No external hosting, re-uploads or third-party distributions are permitted.
This ensures all users operate from a single, reliable source of truth.
Use Governance
The IMME Licence allows:
✔ free internal use
✔ internal adaptations
✔ internal training
But prohibits:
✘ resale
✘ redistribution
✘ public posting
✘ platform embedding
✘ republishing on external sites
This balance ensures global access without loss of control.
AI Governance - IMME NEXUS
IMME IP must never be used to train external or general-purpose AI systems.
Only the official IMME AI (future release) is authorised to:
-
ingest IMME templates
-
use IMME benchmarks
-
apply IMME rates
-
generate IMME-aligned outputs
This protects correctness, safety and long-term data integrity.
Feedback Governance
The Method evolves through community intelligence.
Users are encouraged to:
-
submit suggestions
-
highlight gaps
-
vote on improvements
-
request additions
Immercial reviews all feedback to ensure updates strengthen the global standard.
Communication Governance
Immercial provides:
-
version release notes
-
change logs
-
update announcements
-
methodology improvements
Users should remain aligned by following official communications and migrating to new versions promptly.
Compliance Checks
Immercial may request confirmation of proper implementation to preserve global consistency.
These checks are supportive, lightweight and typically involve:
-
confirming version numbers
-
verifying correct template use
-
reviewing examples for alignment
This keeps the Method clear, consistent and trusted worldwide.

Founded with a unique goal:
To revolutionize how the construction industry manages cost across MEP supply chains.
After years of witnessing the same mistakes and inefficiencies in cost organisation and commercial control, we saw the need for a smarter, scalable shift. Too many projects were derailed not by complexity, but by fragile cost foundations, unclear data, and inconsistent methods in the earliest stages.
Processes across the industry looked similar, yet rarely delivered truly efficient results. Cost plans, estimates, and pricing schedules were structured in ways that left clients exposed to commercial risk. A better way was needed: not only to advise, but to engineer a system capable of delivering excellence every time.
At Immercial, we set out to build a different model. Proprietary systems, software, templates, AI, and emerging technologies replicate expert decision-making and service standards across every project, without the traditional reliance on growing headcount.
Today, this strategy enables us to run multiple projects and serve multiple clients simultaneously. Clients engage with a clear, expert point of contact supported by a powerful, invisible engine of processes and technology that ensures control, clarity, and consistency throughout delivery.
We engineer commercial frameworks that elite clients trust to turn their visions into reality. Where others focus on the finish, we strengthen the start. Robust, repeatable, and transparent systems that set projects up for success and keep them on track.
Our goal is simple: set a new benchmark in MEP commercial cost control. Smarter, faster, and future-proofed by design.
Immercial exists for the industry’s most ambitious clients and projects, those who know that getting it right at the beginning makes all the difference in the end.
A unique approach
What you see is a single expert point of contact, providing precision advice, deep market knowledge, and personal service.
What you don’t see is the extensive technology, systems, and innovation working beneath: an iceberg of built infrastructure designed to deliver consistently for multiple clients, at scale, without the inefficiencies of large staffing models.
Our Foundational Strategy:
Over the past years, we’ve invested in designing, testing, and refining a proprietary ecosystem of software, portals, AI tools, time management algorithms and benchmarking frameworks, built specifically to replicate the owner-level service and thinking Immercial is known for.
Our clients experience seamless, precise, owner-level service, every time, across every project, because of the invisible strength of our systems working tirelessly behind the scenes.
Why It Matters:
Consistency: Every client receives the same elite standard, without dilution.
Efficiency: Projects are delivered faster, with greater accuracy and fewer risks.
Future-proofing: Our technology evolves to market shifts.
Welcome to a new era of commercial consultancy. One blueprint. A system beneath. Excellence above all.
Unlock the potential of your project with our expert services tailored to ensure precision, efficiency, and value at every stage. Our Structured Cost Planning and Benchmarking provides a clear financial roadmap, ensuring your budget is aligned with industry standards, while our Levelling and Recommendations service offers insightful guidance, optimizing project outcomes by addressing potential risks and enhancing performance.
In addition to our core consultancy services, we also offer dedicated Post-Contract MEP Quantity Surveying support. This ensures clients have continuity of commercial oversight beyond the pre-construction phase, retaining the same high standards of cost control and value assurance throughout the live project lifecycle. Whether engaged mid-phase or as a continuation of our early involvement, this service is designed to provide focused, ongoing commercial management through to practical completion and final account closeout.
Structured Cost Planning and Benchmarking
We specialise in early-stage MEP cost consultancy, giving developers and clients a clear, reliable financial roadmap from project inception. Using a structured stage-based approach inspired by the RIBA Plan of Work, our cost plans and benchmarking services deliver data-driven insights to support informed decisions aligned with market trends, project objectives, and budget expectations. Early engagement with our team enables strategic cost forecasting that minimises risk and maximises value throughout the project lifecycle.
Tender return, levelling and Recommendations
Beyond original cost planning stages, we are experts in tender return bid levelling and expert recommendations, ensuring fair, transparent contractor comparisons. Our structured approach leads directly into a seamless preconstruction phase, enabling design teams and contractors to progress with confidence. By setting the financial and technical groundwork in RIBA Stages 0-4, we de-risk projects and establish the foundation for efficient project delivery.
Post contract MEP Quantity Surveying
For clients seeking full commercial continuity, we provide expert post-contract MEP quantity surveying services. With over 25 years of hands-on experience in live project commercial management, we’re uniquely positioned to oversee and manage all project-side MEP cost and contractual tasks during the construction phase and beyond.
