A Guide to the Standards and Best Practices Used by ITAs

Introduction

Technical reports often look impressive, but not all of them carry real weight. The problem many investors, lenders, and project owners face is this: how do you know whether a technical review is reliable, consistent, and defensible? Without clear standards, reviews become subjective, uneven, and hard to trust. That uncertainty creates agitation—especially when big decisions depend on technical findings. The solution is structure. A Guide to the Standards and Best Practices Used by ITAs explains the frameworks, references, and working methods that credible Independent Technical Advisors follow. These standards are not about bureaucracy. They exist to ensure findings are consistent, risks are properly assessed, and decisions are based on evidence rather than opinion.

• Why it matters: Ensures consistency, credibility, and trust

• Who benefits: Investors, lenders, and asset owners

• Outcome: Clear, defensible technical advice

Understanding Why Standards Matter for ITAs

Independent Technical Advisors operate in high-stakes environments. Their findings influence investments, financing, insurance, and long-term asset value. Without standards, two advisors could review the same project and reach very different conclusions.

In A Guide to the Standards and Best Practices Used by ITAs, standards act as a common language. They define what should be reviewed, how it should be reviewed, and how findings should be reported.

Standards help to:

• Reduce subjectivity

• Improve consistency across projects

• Increase stakeholder confidence

• Support defensible decisions

They also protect ITAs by grounding opinions in recognised frameworks.

The Difference Between Standards and Best Practices

Standards and best practices are related but not the same.

• Standards are formal references, codes, or guidelines issued by recognised bodies.

• Best practices are proven methods developed through experience across many projects.

Top ITAs use both. Standards provide the baseline. Best practices fill the gaps where standards are silent or too general.

Core Principles Followed by ITAs

Before specific standards are applied, ITAs operate under a set of core principles.

These include:

• Independence

• Objectivity

• Evidence-based assessment

• Transparency

• Professional accountability

These principles shape how standards are applied in real situations.

International Engineering and Technical Standards

ITAs commonly reference international engineering standards to assess design and construction quality.

Examples include standards related to:

• Structural design

• Electrical systems

• Mechanical systems

• Fire and safety

Using recognised standards ensures work is assessed against accepted industry benchmarks, not personal opinion.

Renewable Energy–Specific Standards

For RE projects, general engineering standards are not enough. ITAs also rely on RE-specific references.

These often cover:

• Solar and wind system design

• Energy yield assessment

• Performance testing

• Degradation assumptions

In A Guide to the Standards and Best Practices Used by ITAs, these standards ensure performance claims are realistic and comparable.

Grid and Electrical Compliance Standards

Grid connection is a critical risk area.

ITAs review compliance with:

• Grid codes

• Protection requirements

• Interconnection standards

Non-compliance here can delay projects or limit operation.

Health, Safety, and Environmental Standards

Safety and environmental performance are non-negotiable.

ITAs typically assess alignment with:

• Occupational health and safety standards

• Environmental management frameworks

• Site safety best practices

These reviews reduce operational and reputational risk.

Quality Management Standards

Quality does not happen by accident.

ITAs assess whether projects follow structured quality systems, such as:

• Document control processes

• Inspection and test plans

• Non-conformance management

Strong quality systems reduce defects and disputes.

Contractual and Technical Specification Alignment

One best practice is aligning technical reviews with contractual requirements.

ITAs check:

• Whether designs meet contract specs

• Whether construction matches approved documents

• Whether deviations are approved

This alignment is critical in disputes and claims.

Best Practices in Technical Due Diligence

During due diligence, ITAs follow structured review processes.

Best practices include:

• Clear scope definition

• Risk-based assessment

• Prioritisation of material issues

This avoids reports filled with minor observations that distract from real risk.

Risk-Based Assessment Approach

Not all risks are equal.

A key ITA best practice is ranking risks based on:

• Likelihood

• Impact

• Ability to mitigate

This helps decision makers focus on what truly matters.

Evidence-Based Reporting

Strong ITA reports rely on evidence.

Best practices include:

• Site photographs

• Reference to drawings and standards

• Clear explanation of findings

This strengthens credibility.

Consistent Report Structure

Consistency improves usability.

Many ITAs follow structured report formats that include:

• Executive summary

• Scope and limitations

• Key findings

• Risk register

• Recommendations

This allows readers to quickly find what they need.

Plain Language Communication

A critical best practice is avoiding unnecessary jargon.

ITA reports should be understandable by:

• Non-technical investors

• Lenders

• Senior management

Clarity improves decision making.

Construction Monitoring Best Practices

During construction, ITAs follow repeatable monitoring routines.

These include:

• Regular site visits

• Progress verification

• Quality checks

• Defect tracking

Consistency ensures trends are identified early.

Use of Checklists Without Losing Judgment

Checklists are useful but not sufficient.

Best ITAs:

• Use checklists as a guide

• Apply professional judgment

• Adapt focus based on site conditions

This balance prevents blind spots.

Documentation Control and Traceability

Strong documentation is a hallmark of good ITA practice.

This includes:

• Clear referencing

• Version control

• Traceable observations

This supports audits, disputes, and claims.

Best Practices in Performance Assessment

Performance reviews require careful handling.

ITAs follow best practices such as:

• Reviewing assumptions

• Validating data sources

• Comparing actual versus expected results

This avoids misleading conclusions.

Commissioning and Testing Standards

Testing proves functionality.

ITAs assess:

• Completeness of test plans

• Compliance with acceptance criteria

• Resolution of failed tests

Incomplete testing is a major risk.

Managing Changes and Variations

Change is inevitable.

Best practices include:

• Reviewing technical justification

• Assessing impact on performance and safety

• Ensuring proper approval

This prevents uncontrolled risk growth.

Interface Management Best Practices

Many issues arise at interfaces between contractors.

ITAs focus on:

• Scope boundaries

• Responsibility clarity

• Coordination effectiveness

This reduces disputes.

Best Practices in Risk Registers

Risk registers are living tools, not static tables.

ITAs update them regularly to:

• Reflect new findings

• Track mitigation actions

• Close resolved risks

This keeps risk visible.

Ethical and Professional Standards

Professional integrity underpins all ITA work.

Best practices include:

• Declaring conflicts of interest

• Maintaining confidentiality

• Reporting honestly, even under pressure

Trust depends on this.

Alignment With Lender and Investor Expectations

ITAs tailor reviews to stakeholder needs.

Best practices include:

• Understanding lender requirements

• Aligning findings with decision points

• Highlighting bankability issues

This improves relevance.

Continuous Improvement and Learning

Top ITAs learn from every project.

They improve by:

• Reviewing past outcomes

• Updating internal methods

• Sharing lessons learned

This keeps practices current.

Local Standards and Regulations

International standards must be adapted to local context.

ITAs also consider:

• Local codes

• Authority requirements

• Regional practices

Ignoring local rules creates risk.

Managing Limitations and Assumptions

Transparency is a best practice.

ITAs clearly state:

• Access limitations

• Data gaps

• Assumptions made

This prevents misunderstanding.

Avoiding Overconfidence

Strong ITAs avoid absolute statements.

They communicate uncertainty honestly and explain its implications.

Common Gaps in Weak ITA Practices

Understanding poor practice highlights good practice.

Weak ITAs often:

• Skip site visits

• Rely heavily on documents

• Avoid ranking risks

Top ITAs avoid these pitfalls.

How Standards Support Dispute Resolution

When disputes arise, standards matter.

ITA findings grounded in recognised standards are harder to challenge.

How Best Practices Reduce Project Risk

Consistent methods reduce surprises.

This is the core value of following best practices.

Using ITA Standards to Compare Advisors

Understanding standards helps clients select better advisors.

Ask about:

• References used

• Reporting structure

• Risk assessment approach

Quality becomes visible.

Why Flexibility Still Matters

Standards guide, but judgment decides.

Top ITAs know when to adapt while staying grounded.

The Balance Between Rigor and Practicality

Overly rigid reviews slow decisions.

Best practices aim for useful, timely insight—not perfection.

Long-Term Value of Standardised ITA Work

Over portfolios, consistent ITA methods improve:

• Risk tracking

• Decision quality

• Stakeholder confidence

Value compounds over time.
