Technical Due Diligence

Technical assessment before you buy, lease, refurbish, or reposition a property. The primary objective is to identify technical risks, potential project constraints, and provide a realistic basis for decisions.

Existing buildings often carry risks that are not immediately visible. Documents may be incomplete. Previous works may not be fully recorded. Building services, structure, fire safety, roofs, façades, tenant areas, or operational restrictions can affect the cost and programme of a future project.

Technical Due Diligence helps create a clear picture before important decisions are made. It gives clients a structured view of the property condition, known risks, possible constraints, and next steps.

Technical Due Diligence Supports Decisions Around

  • Property acquisition
  • Lease or rental decisions
  • Risk review before contract commitment
  • Refurbishment and repositioning
  • Budget planning
  • Tenant improvements
  • Project feasibility
  • Fit-out projects
  • Change of use

Why It Matters

Technical issues in existing buildings can quickly become cost, time, and contract issues.

‍

A clear assessment at the beginning helps avoid unrealistic assumptions. It gives the project team a better basis for planning, procurement, negotiation, and delivery.

‍

Christian Voß Consulting brings a project management perspective to Technical Due Diligence. This means the review does not stop at identifying defects. It also considers what the findings mean for execution, budget, schedule, stakeholders, and project risk.

Technical Due Diligence Process

01.
Scope Definition

The assignment is defined around the property, the transaction or project context, and the decision the client needs to make.

02.
Document Review

Available drawings, permits, reports, maintenance records, fire safety information, and technical documents are reviewed to identify known information and missing information.

The goal is to separate what is confirmed, what is unclear, and what requires further verification on site.

03.
Property Inspection

The property is inspected with attention on visible condition, technical risks, and project-relevant constraints.

The inspection is not treated as a standalone checklist. Findings are assessed in relation to the client’s intended use, planned works, budget assumptions, and delivery risks.

04.
Risk and Impact Assessment

Findings are assessed according to their impact on cost, programme, safety, operation, leasing, and planned works.

This gives the client a clear view of what needs immediate attention, what should be planned for, and what may affect negotiations or project setup.

05.
Specialist Coordination

Findings are assessed according to their impact on cost, programme, safety, operation, leasing, and planned works.

This gives the client a clear view of what needs immediate attention, what should be planned for, and what may affect negotiations or project setup.

06.
Reporting

The result is a practical technical assessment with key findings, risk areas, open questions, and recommended next steps.
