The practice

One team for
the full
building services
lifecycle.

Hospital theatre shutdowns. Tier-III data centre black-building tests. High-spec commercial handovers. The projects that punish loose paperwork and reward real technical discipline.

Maiden Ventures is engaged across all of it — by owners, builders, developers and PMOs — to run building services from the first feasibility sketch right through to post-handover tuning. We write the Cx plans and the risk matrices. We run the services tenders and secure exclusive subcontractor pricing. We do the in-house clash detection and coordination, monitor the build, then commission the finished job.

Same principals, same standards, every engagement. Write precisely, coordinate tightly, close defects before handover. When the lights come on, they stay on.

Services

Services management, ICA and specialist engagements — the whole building services lifecycle, under one roof.

01

Services Management Feasibility → Handover

The one-stop engagement. End-to-end building services leadership running across every phase of a project — the same team from the first feasibility sketch to the last defect closed.
  • Feasibility: DA design assistance, cost planning, spatial advice
  • Bid phase: bid assembly, Value Engineering, risk matrix, clarifications
  • Post-award: services tenders & exclusive subcontractor procurement
  • Design: in-house clash detection, coordination, technical reviews
  • Construction: site monitoring, progress & QA verification
  • Handover: commissioning, tuning, DLP defect closure
Full lifecycle
One team
02

Independent Commissioning Agent — ICA

The dedicated ICA role — independent of the design team, head contractor and services subcontractors. The nominated role for Green Star Verification & Handover credits.
  • Commissioning Plans (CxP), Acceptance Criteria, ITPs
  • FAT / SAT / iBST / IST witnessing & verification
  • Defect burn-down, completion gates, O&M sign-off
  • Green Star Verification & Handover credit support
Independent
Verified
03

Bid Assistance & Value Engineering

Pre-contract support for Tier-1 and specialist builders. We help put the services bid together — take-off, pricing, VE proposals, risk matrices and the clarifications schedule that wins (or saves) the job.
  • Services bid assembly & pricing validation
  • Value Engineering initiatives & alternatives
  • Risk matrix development & quantification
  • Clarifications schedule & technical assumptions
  • Design-risk & commissionability review pre-tender

04

Exclusive Subcontractor Procurement

Post-award services tender management. We run the services packages and secure exclusive pricing from our established subcontractor network — mechanical, electrical, hydraulic, fire, ICT and medical gas.
  • Services tender strategy & documentation
  • Exclusive subcontractor pricing — established relationships
  • Scope gap analysis & package interface alignment
  • Technical specification & compliance verification
  • Award recommendations with risk profiling
Post-award

05

ICN Design & Integration

Integrated Communications Network engineering — from segmentation strategy to a clean handover pack your IT team will actually accept.
  • VLAN / VRF segmentation & east-west isolation
  • IPAM, firewall allow-lists, identity & access
  • BACnet/SC readiness, BMS/lighting/metering/security/VT
  • As-built diagrams, asset registers, O&M bundles
Enterprise IT
Coordination
The approach

Five phases. One team. Start to finish.

Phase 01 —
Feasibility & DA
DA design assistance, services cost planning, spatial advice. Services strategy aligned to brief, budget and program before consultants lock the building in.
Phase 02 —
Bid & procurement
Bid assembly, Value Engineering, risk matrix, clarifications schedule. Post-award, we run the services tenders and secure exclusive subcontractor pricing.
Phase 03 —
Design coordination
In-house clash detection across MEP, hydraulic and fire services. Technical reviews, constructability, ITP gap analysis, standards alignment (AusHFG, NCC, AS/NZS).
Phase 04 —
Construction monitoring
Site monitoring, installation audits, progress & QA verification against drawings and specs. Variations assessed. Vendor FATs witnessed. Interface risks flagged early.
Phase 05 —
Commissioning & close
SAT, iBST, IST witnessing. Performance tuning. DWN-gated cutovers on live-environment works. DLP defect closure, NABERS commitment verification, Green Star V&H credit sign-off.

Common questions

Straight answers before the first site walk.

If your question isn’t here, it’s probably faster to just ask. Most enquiries get a scoped response within one business day.

Everything building-services related on a project, phase by phase. In feasibility that means DA design assistance, services cost planning and spatial advice. In bid phase we help put the services submission together — take-off, VE, risk matrix, clarifications. Post-award we run the services tenders and procure exclusive subcontractor pricing. During design we do in-house clash detection, coordination and technical reviews. Through construction we monitor the build. At the end we commission, tune, and close out defects. One team, one accountability, start to finish.
Owners, developers, builders and PMOs — the engagement type dictates the client. Services Management is commonly engaged by owners or developers running complex programs. Bid Assistance and Exclusive Subcontractor Procurement are typically builder-side. The ICA role is, by definition, independent of the design team and head contractor for that specific engagement — but as a firm we deliver services across all parties to a project.
The ICA plans, coordinates and independently verifies commissioning across MEP, BMS, ICN, security and essential services. In a typical Sydney hospital or A-Grade commercial project that means writing the Commissioning Plan, defining acceptance criteria, witnessing FAT/SAT/IST, managing the defect register, and confirming the building is genuinely ready for handover. The ICA role is the designated path to Green Star Verification & Handover credits.
Once the builder is awarded the head contract, we run the services tender packages — mechanical, electrical, hydraulic, fire, ICT, medical gas — against our established subcontractor network. The “exclusive” part is the pricing: through recurring relationships and structured package documentation we secure pricing that isn’t available through open tender. Clients get a documented award recommendation with scope coverage, interface risks and value profile set out clearly.
A gated Disruption Works Notice (DWN) process: risk assessment, redundancy & temporary services plans, stakeholder communications, freeze windows and — critically — rollback criteria agreed before the outage begins. Clinical and facilities teams approve the shutdown window in advance. The outcome is short, safe, reversible outages rather than open-ended disruption.
An Integrated Communications Network securely connects building systems — BMS, lighting, metering, security, VT — across a shared but segmented network. It needs its own engineering because enterprise IT won’t (and shouldn’t) accept a flat, vendor-whatever network. We design the segmentation, VLAN/IP plan, firewall allow-lists and BACnet/SC readiness, then hand over a clean as-built pack the client’s IT team can actually operate.
AusHFG, the NCC, AS 1668 (mechanical ventilation), AS 1851 (fire maintenance), AS/NZS 3000 (electrical installations), AS/NZS 2293 (emergency lighting), NFPA 99 / ISO 7396-1 / HTM 02-01 (medical gas), ASHRAE Guideline 0 and CIBSE Code M — plus project-specific requirements. On Green Star projects we deliver to the Verification & Handover credit; on TfNSW projects we work within T HR CI 12051 (CIMP).
Sydney and NSW are the primary focus. We regularly travel for projects elsewhere in Australia and across New Zealand, particularly for hospital and data centre work where specialised building-services capability is scarce.
A short discovery call to understand program, scope, standards and stakeholders. From there we issue a scoped proposal with a fixed fee or time-based engagement and a clear set of deliverables tied to project milestones. NDAs are standard and can be executed on request.
