Property Development Advisory · NSW

A builder's brain
applied to site viability.

Contender Group brings construction literacy, design intelligence, and systemic project governance to the feasibility, DA management, and delivery of Tier 2 and Tier 3 development projects — with an in-house building arm for seamless execution when it matters most.

NSW-wideOperating footprint
What we bring to every engagement
01
Construction-grade feasibility
We read a site the way a builder does — structure, staging, programme, and margin — not just IRR and a residual land value.
02
Design parameters we can move
When a site is stalling, we identify which design levers to pull — GFA, typology, structure, specification — and quantify the margin impact.
03
Systemic contract governance
Every communication, variation, and contract mechanism managed to a standard that stands up to audit, adjudication, or a funder's due diligence.
04
In-house delivery option
Advisory that can transition seamlessly into construction. One team, one accountability chain, from first feasibility number to final defect.
Where We Add Value

The construction insight your advisory team doesn't have to carry alone.

Most development managers and feasibility tools do exactly what they are designed to do — coordinate, communicate, and calculate. What Contender Group adds is a different layer: the practical construction intelligence and design manipulation capability that turns a good process into a great outcome.

The Gap We Fill

Construction Depth Behind the Advisory

Development managers are typically strong coordinators — managing consultants, tracking approvals, and keeping stakeholders informed. Where Contender Group complements that capability is in the construction layer: reading a builder's cost plan with the eye of a practitioner, identifying where design decisions are eroding margin, and knowing which parameters can be adjusted to recover a site's viability. That is a specific, builder-side skill set that sits alongside — not in place of — strong project coordination.

  • Independent interrogation of builder cost plans and tender submissions
  • Design parameter adjustment — GFA, typology, structure, specification
  • Construction programme logic embedded into feasibility analysis
  • Contract administration under AS 4000 / GC21 frameworks
  • Proactive SOPA compliance — protecting the principal's payment position
The Gap We Fill

Live Construction Intelligence in the Feasibility Model

Standard feasibility tools — whether spreadsheet-based or platform-based — are built to calculate inputs you provide. What they cannot do is tell you which inputs to change, or what happens to your margin when you switch structural systems, reduce the car park, or adjust the unit mix. Contender: Vantage is built specifically to close that loop — blending live financial analytics with construction-aware cost logic, so the feasibility model becomes an iterative design tool, not just a scorecard.

  • Trade-level construction cost logic — not category approximations
  • Live variable adjustment with real-time margin recalculation
  • AI-generated risk flags and scenario comparisons
  • Board and lender-ready PDF export — not just internal worksheets
  • Designed to complement your existing analysis — not replace your process

Contender: Vantage — PropTech Platform

The intelligence engine behind the advisory.

Vantage is not a feasibility spreadsheet. It is a construction-aware valuation engine that blends live financial analytics with practical building logic — allowing real-time manipulation of design variables to make marginal sites viable, and to produce board-ready reports that lenders and investors can rely on.

How We Work

The same senior team.
From day one to final defect.

Contender engagements follow the project — not a phase-based handoff model. The practitioner who ran your initial feasibility is the same person managing your contract administration at practical completion.

Phase 01
Site Feasibility & Acquisition
Construction-led feasibility via Vantage — trade-level cost logic, design parameter testing, staging analysis, and residual land value. Independent review of vendor feasibilities. Due diligence coordination and offer structuring. We give you the bankable number before you commit — and we tell you exactly what has to be true for it to hold up under stress.
Phase 02
Design Development & DA Advancement
Consultant team assembly, design milestone reviews, and DA strategy through to lodgement. Every design decision is tested against the feasibility model — we identify cost creep early and reshape parameters before they become variations. Council pre-lodgement management, VPA structuring, and approval pathway management through to CC or CDC.
Phase 03
Procurement & Contract
Tender strategy, builder selection, and contract negotiation under AS 4000 or GC21 — with Vantage Pro cost benchmarking as the independent reference point. We have sat on both sides of this table. We know what a good contract looks like, what a bad one costs, and where the risk transfer language that sounds standard is actually catastrophic for a principal.
Phase 04
Delivery, Close-Out & Defects
Programme monitoring, cost reporting, claims management, and variation control through construction. Proactive SOPA compliance. Defects inspection, rectification management, OC coordination, and settlement facilitation. We do not leave until the project is closed — not until it is convenient to leave. For eligible projects, the Contender in-house building arm is available to assume direct delivery responsibility under a construction contract.

Principal Consultant, WestInvest State Government Funding Initiatives
Director of Systems & Delivery — Nexus Platform & Contender: Vantage PropTech Engine

Alexander Allan is a project delivery strategist, contract administrator, and corporate governance professional specialising in property development advisory and commercial construction. Holding a Bachelor of Construction Project Management from the University of Technology Sydney (UTS), a licensed builder, and a registered practitioner under the NSW Building Commission's Building Practitioners framework, he brings a rigorous statutory and practical builder's perspective to site feasibility, design management, and client-side project delivery — bridging the gap between financial modelling and real-world site execution.

Alexander operates at the intersection of construction reality, risk management, and corporate oversight. As Chair of the Canterbury Olympic Ice Rink, he leads a not-for-profit board of directors in navigating governance requirements and risk frameworks to deliver a major, publicly funded infrastructure redevelopment. His primary focus across all ventures is eliminating the administrative blind spots, reactive variations, and flawed logic that routinely stall Tier 2 and Tier 3 property developments.

"Good development managers and capable feasibility tools are not in short supply. What is rare is someone who can stand at the intersection of financial modelling and site construction, read the same numbers a builder reads, and find the design path that actually makes a project work. That practical, builder-side capability is what Contender Group was built to provide — not as a replacement for good advisory teams, but as the construction intelligence layer that makes them stronger."
