Technical Due Diligence

Summary

Technical due diligence (TDD) is the structured evaluation of environmental, geotechnical, structural, and compliance risks associated with a property or project. It supports informed decision-making for acquisitions, financing, redevelopment, and construction planning.

Definition

Technical Due Diligence is a comprehensive review of a site’s physical, environmental, and regulatory conditions to identify risks, liabilities, constraints, and opportunities that may affect property value, development feasibility, or project delivery. TDD integrates environmental science, engineering, planning, and regulatory analysis to deliver a clear risk profile for investors and project stakeholders.

Why It Matters

Technical due diligence is essential for mitigating financial, environmental, and regulatory risk—particularly for complex or high-value property transactions. Without a thorough assessment, buyers and financiers may unknowingly inherit costly liabilities or face delays and compliance issues.

TDD helps stakeholders:
‍

• identify contamination, landfill, groundwater, or vapour risks
• understand geotechnical constraints that influence design and construction
• review planning controls, zoning, and approval pathways
• assess operational or legacy risks from historical uses
• estimate remediation costs and development viability
• verify compliance with environmental, health, and safety requirements
• support negotiation, financing, and risk allocation in contracts
  ‍

In Australia, TDD is especially important for brownfield sites, industrial assets, infrastructure corridors, and redevelopment precincts where environmental and geotechnical constraints can significantly impact feasibility.

When It’s Required

Technical due diligence is typically undertaken before acquiring, financing, or redeveloping a property or infrastructure asset. Common triggers include:

Property Acquisition or Leasing

Investors or tenants require assurance that a site is free from significant environmental or structural risks.

Brownfield Redevelopment

Sites with historical industrial or commercial uses often require detailed investigations to assess contamination, landfill conditions, and geotechnical stability.

Infrastructure and Civil Projects

Route selection, design feasibility, and risk evaluation often rely on comprehensive TDD inputs.

Financing and Loan Approval

Banks and equity partners frequently require technical due diligence to quantify liabilities and validate project assumptions.

Planning and Development Pathway Assessment

Understanding approvals, constraints, and site sensitivities informs staging and cost planning.

Environmental or Compliance-Driven Triggers

EPA notices, audit recommendations, or compliance risks may require specialist due diligence to inform remediation or closure strategies.
