Building services engineering for a wide range of commercial, multi-residential and industrial developments
CPDT Consulting views quality engineering as practical, human-led engineering that balances real-world performance and long-term maintainability with respectful collaboration between trade partners. Building services decisions made early can affect comfort, energy use, available space, construction cost and ongoing maintenance for years to come.
CPDT Consulting helps project teams work through those decisions before layouts and system choices are locked in. Jonathan Foster personally provides the engineering, bringing experience since 1997 to the coordination of mechanical, hydraulic, pool water, gas and controls systems.
That means clients get direct access to the person making the engineering decisions, with building systems considered together rather than as isolated packages.
Contact Jonathan to discuss your project, where early input for building services adds value.

Building Services Engineering - Overview:
CPDT Consulting provides building services engineering design that helps project teams make better-informed decisions around coordination, performance and long-term building costs.
- Deal directly with the chartered engineer making the design decisions
- Coordinate HVAC, hydraulic, pool water, gas and controls as connected systems
- Identify plant space, service routes and maintenance access before layouts are fixed
- Compare options across construction cost, running cost, flexibility and system life
- Understand existing system condition before committing to refurbishment or purchase
- Keep engineering support available through construction where required
CPDT Consulting is a Wellington-based building services engineering consultancy providing HVAC, hydraulic and commercial pool water design for projects throughout New Zealand.

CPDT Consulting is based in Wellington and provides building services engineering for projects throughout New Zealand.
One engineering view across connected building systems
Buildings perform best when their core services are designed as a single, connected ecosystem.
CPDT Consulting coordinates mechanical and hydraulic services, pool water treatment, gas reticulation, and controls under one roof - working alongside architects, structural engineers, and contractors to eliminate design clashes and keep the team working from clear, accurate plans.
Controls and Building Management Systems (BMS) are integrated early to lock in operating schedules, temperature targets, and energy efficiency targets. For complex aquatic facilities, for example, pool water services, HVAC, hydraulics and humidity controls directly impact one another - this holistic approach ensures every system works together seamlessly.
Where another specialist discipline is required, Jonathan is clear about that from the outset and can recommend appropriately qualified consultants.

Early coordination of layouts and replacement access
Early building services engineering gives project teams the space to make smart decisions while designs are still flexible.
CPDT Consulting considers plant space, risers, ceiling voids, service routes, and maintenance access before architectural plans are locked in - preventing unsuitable service spaces and expensive site variations during construction.
Long-term operation and future planning is built in from day one. Mechanical equipment will eventually need servicing or replacement, so removal routes are planned early to avoid costly future demolition.
Specialist 3D design software is used to support coordination and provides clear documentation for consent and streamlines buildability on site.

System choices based on whole-life performance
The lowest initial cost is not always the lowest cost over the life of a building.
Jonathan compares realistic design options against the priorities of the project, including design cost, construction cost, energy use, maintenance, flexibility and expected system life.
Calculations and energy modelling help provide a technical basis for those decisions, so clients can understand the trade-offs rather than being presented with a single preferred solution without context.
Jonathan also assesses products and systems on their engineering merits rather than simply accepting manufacturer claims or familiar industry habits.
The same approach carries through to specialist services such as HVAC design and hydraulic engineering, where system choices can have a significant effect on future operating and replacement costs.
Building assessments and construction-stage support for your project
For an existing building, knowing the condition and likely remaining life of its services can make refurbishment, purchase and capital planning decisions much easier.
CPDT Consulting provides due diligence inspections, condition assessments and refurbishment reports to help identify what is working, what may need attention and where future investment is best directed.
These assessments include practical, transparent advice on technical options—outlining their pros and cons to support long-term planning.
Jonathan can also stay involved during construction with site observations, technical queries, commissioning support, and final review or sign-off so that the project stays to the agreed scope.

As early as practical. Involving Jonathan before layouts and key design decisions are fixed gives the wider project team more opportunity to consider plant space, service routes, access, system options and long-term performance before changes become more difficult or expensive.
We integrate heating, ventilation, and air conditioning (HVAC), hydraulic plumbing, commercial pool water treatment, gas reticulation, and Building Management Systems (BMS) controls. Coordinating these connected building services together eliminates conflicting requirements and gives the wider project team clear, accurate documentation to work from.
You deal directly with Jonathan Foster, a chartered engineer to ensure project knowledge and design responsibility stay with the same senior engineer from initial concepts right through to construction oversight and final sign-off.
Yes. For existing facilities, CPDT Consulting provides due diligence inspections, condition assessments, and refurbishment reports. We evaluate remaining plant lifespan, help you understand current performance, and outline practical options before you commit to purchase, capital upgrades, or major refurbishments.
