The problem
Most mechanical services projects fail on paper long before they fail on site.
Scope written without delivery experience
Tenders that read well and price badly. Ambiguity in the specification becomes a variation claim in month four, and the asset owner carries it.
Capex bids that cannot survive scrutiny
Chiller replacements and plant room modernisations get deferred year after year because the technical case and the financial case were never written by the same hand.
Compliance discovered, not managed
Essential services gaps surface in an audit rather than in a programme. In a hospital, a correctional centre or a Defence estate, that is not a paperwork problem.
Full contract lifecycle
Specification and tender through to performance monitoring and exit.
Capex and opex models
Keeping facilities inside budget while holding compliance.
Regulatory landscape
AS 1668.2, NCC, Building Regulations, health facility guidelines, ASDEFCON, corrections standards.
Commercial perspective
Technical compliance balanced against financial sustainability — not engineering for its own sake.
Both sides of the table, in one adviser.
The difference
Rob built and led the organisations that deliver these services, so he knows what good delivery looks like from the contractor side — and exactly where the gaps usually are. He has also personally conducted the dilapidation assessments, condition reports and engineering evaluations that inform capital planning decisions.
Services
Three engagements that carry the most risk — and the most upside.
ALSO ENGAGED FOR
Capital expenditure forecasting
Capex models for asset lifecycle planning — chiller replacement, AHU upgrades, BMS refresh, plant room modernisation. Data-driven and aligned to budget cycles.
Planned maintenance programming
Preventive maintenance schedules for critical facilities, integrated with BMS and CMMS platforms for live asset performance monitoring.
Essential services testing & verification
Fire dampers, smoke control, pressurisation systems and emergency HVAC, reported to AS/NZS and state Building Regulations.
BMS & controls strategy
Specification, commissioning, optimisation and compliance — energy management, alarm management, trending, and integration with enterprise asset systems.
Technical engineering reporting
Authoritative reports on asset condition, compliance status, risk and remediation — written to withstand audit, insurance and regulatory scrutiny.
HVAC & mechanical-electrical
Split systems, VRF, ducted, chilled water plants, air handling units, cooling towers, controls and mechanical-electrical interface coordination.
Sector experience
Environments where downtime is not an option.
Government facilities operate under intense budgetary and regulatory scrutiny. These are the settings Rob has personally delivered in.
Hospitals & healthcare
Operating theatres, isolation rooms, ICU and wards. Infection control air handling, pressure-regulated zones, medical gas interfaces, central energy plants, chilled water distribution. AS 1668.2 and health facility guidelines.
Laboratories &
clean rooms
Pathology, research, PC2/PC3 containment and pharmaceutical clean rooms. HEPA integrity testing, particle counting, airflow visualisation, room pressurisation, NATA-aligned verification.
Corrections
Secure-environment mechanical services — hardened HVAC equipment, anti-ligature design, controlled airflow systems, and compliance with corrections-specific engineering standards.
Defence — naval & army
Defence-grade HVAC and refrigeration. Commonwealth security clearance, ASDEFCON procurement compliance, delivery on Defence estates including workshops, barracks and specialised technical facilities.
Universities & education
Campus-wide HVAC and BMS integration across multiple buildings, lecture theatre conditioning, research laboratory environments, central plant management, capital works coordination.
Performing arts theatres
Precision temperature and humidity control for stage and auditorium. Acoustic-sensitive mechanical design, low-noise air distribution, integration with stage lighting and performance schedules.
Commercial facilities
Large-scale commercial HVAC, BMS-controlled environments, essential services compliance and energy optimisation across office towers, retail centres and mixed-use developments.
Selected engagements
$13M of critical plant. Zero downtime.
Recent Queensland projects delivered under Rob’s leadership as Managing Director. Each facility stayed operational through the changeover.
