Revit BIM modelling, CFD simulation and hydraulic analysis — coordinated, clash-free MEP designs with airflow and pipe sizing validated before a single component reaches site.
Service Overview
What we deliver
The cheapest place to fix an engineering problem is inside the model. A duct that clashes with a beam costs minutes to move in Revit and days to move on site. An air-conditioning layout that leaves hot spots is a simulation run during design — or a complaint log after occupation. TechMEPi Engineering builds its entire practice on this principle: model first, simulate early, build once.
We offer BIM and engineering simulation both as the backbone of our own MEP designs and as a standalone service for developers, architects, fellow consultants and contractors who need modelling or analysis capacity on their projects.
Our toolset
Autodesk Revit — full BIM modelling of mechanical, electrical and plumbing services; clash detection and coordination before construction
Autodesk CFD — simulation of airflow, heat transfer and fluid behaviour for HVAC optimisation and energy efficiency
Pipe Flow Expert — hydraulic calculations for pumped and gravity piping systems
Autodesk Inventor — detailed 3D mechanical modelling and simulation
AutoCAD — precise 2D drawings, schematics and installation documentation
Our approach
Every services design begins as a coordinated model. Ductwork, pipework, cable containment and equipment are modelled at real dimensions and clash-checked against structure, architecture and each other, so conflicts are resolved on screen rather than negotiated between trades on site. The same model produces consistent plans, sections, schedules and builder's work drawings — one source of truth from concept to as-built.
Simulation then tests the design before it is built. CFD studies show how air actually moves through an atrium, a plant room, a server room or a hospital ward: temperature distribution, velocity, stagnation zones and the effect of equipment placement. Hydraulic analysis verifies pump duties, pipe sizes and system balance, replacing rule-of-thumb allowances with calculated results. The outcome is plant that is correctly sized — neither wastefully large nor marginal.
What we deliver
Coordinated Revit MEP models to agreed level of detail
Clash detection and coordination reports
CFD airflow and thermal simulation studies
Hydraulic calculation reports and pump selections
2D construction documentation extracted from the model
Design visualisations for client and stakeholder review
Why it pays
Digital workflows are the core of TechMEPi's competitive advantage: higher design accuracy, fewer errors on site, better coordination between disciplines, faster delivery and predictive simulation that reduces risk before implementation. Clients see the difference in fewer variations, shorter programmes and systems that perform as designed from day one. The model then lives on after construction as an accurate as-built record for operation, maintenance and future refurbishment.
Standards
Our modelling and information workflows are aligned to the principles of ISO 19650 for managing information with BIM, and simulation results are assessed against recognised comfort and performance criteria such as ASHRAE guidance for indoor environments. Deliverables are agreed up front — model scope, level of detail and formats — so outputs integrate cleanly into your project's wider information environment.

FAQ
Common Questions
What does BIM actually save on a project?
Mostly rework and time. Clash detection resolves conflicts between ducts, pipes, cables and structure while they are still lines in a model, which means fewer site variations, less abortive work and shorter programmes. Coordinated drawings and schedules all come from one model, so documentation stays consistent. On our projects, digital coordination is a principal reason for reduced errors and faster delivery.
What is CFD simulation used for in buildings?
Computational fluid dynamics predicts how air and heat behave in a space before it is built. We use it to verify air-conditioning layouts, check temperature distribution in server rooms and plant rooms, study ventilation in large or complex volumes, and optimise equipment placement for energy efficiency. It replaces guesswork with evidence — you see the hot spots and stagnant zones on screen, not after occupation.
Can you provide BIM or simulation services on a project you did not design?
Yes. We regularly support architects, consultants, contractors and developers who need MEP modelling, clash coordination, CFD studies or hydraulic calculations as a discrete package. We work to your project's BIM requirements and agree scope, level of detail and deliverable formats at the outset, so our models and reports slot directly into your existing workflow.
Can existing buildings be modelled for refurbishment work?
They can. Working from surveys, existing drawings and site inspection, we build a Revit model of the current services as a baseline, then design the refurbishment against it. This is particularly valuable in occupied buildings — hospitals and hotels especially — where new services must thread through congested ceilings and risers, and where clashes discovered during construction are most disruptive.
