Builder Dispute Support intro

Support When a Building Project Starts to Go Wrong

Building disputes can develop for many reasons.

A disagreement may begin with something relatively small, such as a variation, delayed payment or unclear item in a quotation, and then become more difficult as the project progresses.

Common problems include:

  • Disagreement over what was included
  • Unexpected additional costs
  • Delays
  • Poor workmanship
  • Work not matching the drawings
  • Disagreement over variations
  • Incomplete work
  • Payment disputes
  • Defects
  • Breakdown in communication
  • Disagreement over completion
  • A builder leaving site before the work is finished

When a construction dispute develops, the first priority is usually to establish what has actually been agreed, what work has been completed and where the disagreement has come from.

At Tholos Architects, we can help clients review the architectural and construction information surrounding a dispute and bring greater clarity to the technical issues involved.

We are not a substitute for a solicitor where legal advice is required, but architectural and technical input can be extremely useful when the dispute relates to drawings, scope, workmanship, variations or the condition of the work.

Start Your Project

Why Builder Disputes Happen

Construction projects involve many separate decisions.

These can include:

  • Design
  • Specification
  • Materials
  • Cost
  • Programme
  • Responsibility
  • Changes during construction

If those decisions are not clearly documented, different people can end up believing that different things were agreed.

Disputes often arise from a combination of:

  • Unclear documentation
  • Incomplete drawings
  • Poorly defined scope
  • Verbal agreements
  • Changes made during construction
  • Unexpected conditions
  • Cost increases
  • Poor communication

The earlier the underlying issue is identified, the easier it may be to resolve.

Builder Dispute Support explained

What Does Builder Dispute Support Mean?

Builder dispute support can involve reviewing the project information to understand the technical and contractual background to the disagreement.

Depending on the situation, this may include reviewing:

  • Architectural drawings
  • Structural information
  • Specifications
  • Quotations
  • Contracts
  • Variation records
  • Emails
  • Site photographs
  • Progress information
  • Building Control information

The purpose is to establish a clearer picture of what was designed, what was priced and what appears to have been constructed.

Work Not Matching the Drawings

One common source of disagreement is work that does not appear to match the approved or construction drawings.

Examples may include:

  • Different dimensions
  • Different materials
  • Openings in different locations
  • Altered roof forms
  • Missing structural elements
  • Different internal layouts
  • Changed external details

The first step is to establish which drawings were actually issued for construction.

Drawings can go through multiple revisions, so it is important to compare the completed work against the correct version.

Workmanship Disputes

Clients and builders can disagree about whether work has been completed to an acceptable standard.

Concerns may relate to:

  • Finishes
  • Alignment
  • Junctions
  • Waterproofing
  • Roofing
  • Joinery
  • Tiling
  • External detailing
  • Making good

Not every cosmetic imperfection represents defective construction.

Equally, some issues may have technical consequences beyond appearance.

A site review can help identify what the issue actually is before decisions are made about remedial work.

Disputes About What Was Included

Scope disputes are extremely common.

A homeowner may believe something was included while the builder believes it was excluded.

This can happen with items such as:

  • Flooring
  • Decoration
  • Kitchen installation
  • Sanitaryware
  • Landscaping
  • Electrical fittings
  • Waste removal
  • Scaffolding
  • External works

The relevant documents need to be reviewed together.

These may include:

  • Drawings
  • Builder quotation
  • Specification
  • Contract
  • Emails
  • Variation records

One document alone may not tell the whole story.

Builder Quote Disputes

A quotation can become a source of disagreement where it is:

  • Vague
  • Incomplete
  • Based on assumptions
  • Missing exclusions
  • Missing allowances
  • Based on outdated drawings

A dispute may arise because the builder believes additional work falls outside the quotation while the client believes it was already included.

Building Contract Disputes

The building contract may help establish:

  • Scope
  • Price
  • Programme
  • Payment terms
  • Variation procedures
  • Completion arrangements
  • Responsibilities

Problems can arise where:

  • The contract is unclear
  • The contract conflicts with the quotation
  • The wrong drawings are referenced
  • Important agreements were made verbally
  • Changes were not documented

Architectural review can help identify inconsistencies between the project documents.
Legal interpretation of the contract should be handled by an appropriately qualified legal professional.

Variation Disputes

Changes during construction are normal.

Problems arise when there is disagreement over:

  • Whether the work was a variation
  • Who requested it
  • Whether the cost was agreed
  • Whether the change affected the programme

Ideally, variations should record:

  • Description of change
  • Reason
  • Cost
  • Programme impact
  • Approval

Where this has not happened, the project records may need to be reviewed retrospectively.

Unexpected Additional Costs

Additional costs can arise from legitimate unforeseen conditions.

Examples include:

  • Hidden structural problems
  • Drainage issues
  • Rotten timber
  • Poor previous construction
  • Unexpected ground conditions

The key questions are usually:

  • Was the issue genuinely unforeseen?
  • Was the client informed?
  • Was the additional work explained?
  • Was the cost agreed?
  • Was the work necessary?

Good records can be crucial.

Disputes About Delays

Construction delays can arise for many reasons.

These may include:

  • Contractor resourcing
  • Material delays
  • Weather
  • Client changes
  • Late decisions
  • Design changes
  • Unexpected site conditions

The first task is often to establish what actually caused the delay.

Reviewing:

  • Programme
  • Emails
  • Site records
  • Variation history
  • Material orders

can help build a clearer timeline.

Builder Has Stopped Coming to Site

One of the most stressful situations is when progress slows dramatically or the contractor stops attending site.

Before taking major action, establish:

  • What work has been completed
  • What remains unfinished
  • What payments have been made
  • What materials are on site
  • What the contract says
  • Whether the builder has formally suspended work
  • Whether there are outstanding disputes

If the relationship is close to breaking down completely, legal advice may be appropriate before terminating a contract or appointing someone else.

Builder Has Left the Project

If a contractor has left the project, the immediate priority is often to understand the physical condition of the works.

This may involve checking:

  • Weather protection
  • Structural stability
  • Openings
  • Temporary support
  • Services
  • Security
  • Water ingress risk

The unfinished work may need to be documented before another contractor changes it.
Photographs, drawings and a written record can be extremely useful.

Incomplete Building Work

Incomplete work should be documented clearly.

This may include:

  • Unfinished rooms
  • Missing finishes
  • Incomplete services
  • External works
  • Unfinished roofing
  • Missing fittings
  • Outstanding certification

A structured list can help distinguish between:

  • Work not started
  • Work partially completed
  • Work completed but defective
  • Work requiring inspection

This information can then be used when discussing completion with the existing builder or obtaining prices from another contractor.

Defective Work

Where work may be defective, avoid jumping immediately to a solution.

First establish:

  • What was designed
  • What was built
  • What the technical issue is
  • Whether the problem is cosmetic or functional
  • Whether further investigation is needed

In some cases, specialist input may be required from:

  • Structural engineer
  • Building surveyor
  • Roofing specialist
  • Damp specialist
  • Other technical consultants

Tholos can help identify when additional expertise is appropriate.

Snagging vs Defects

Not every outstanding item is a major defect.

A snagging list commonly deals with minor matters such as:

  • Paint finishes
  • Sealant
  • Small adjustments
  • Minor making good
  • Final fittings

More significant defects may involve:

  • Structure
  • Weatherproofing
  • Drainage
  • Fire safety
  • Building envelope

Separating minor snagging from more serious concerns can make discussions with the builder much clearer.

Payment Disputes

Payment disputes may arise where:

  • Builder requests more money than expected
  • Client believes work is incomplete
  • Variations are disputed
  • Stage payment definitions are unclear
  • Final account differs from the agreed price

Before withholding or making significant payments, the relevant contract terms should be understood.

Where necessary, obtain legal advice.

Architectural input can help establish what work appears to have been completed relative to the design and scope.

Disagreement Over Percentage Complete

Clients and builders may disagree about how much of the project has been completed.

A progress review can consider:

  • Work completed
  • Work outstanding
  • Materials installed
  • Major construction stages

However, percentage completion is not always the same as percentage of contract value.

Different stages of construction can have very different costs.

Disputes About Materials

Sometimes a dispute relates to materials rather than workmanship.

Examples include:

  • Wrong bricks
  • Different windows
  • Alternative insulation
  • Different roof covering
  • Different flooring
  • Substituted fittings

The project documents should be checked to establish whether the material was:

  • Specified
  • Approved
  • Changed
  • Left to contractor selection

Unauthorised Changes

A builder may sometimes make a change because they believe it is:

  • Easier
  • Cheaper
  • More practical
  • Necessary on site

That does not automatically mean the change is acceptable.
Where the design has been altered without agreement, establish:

  • What changed
  • Why
  • Whether technical approval was required
  • Whether planning or Building Regulations implications exist

Builder Dispute Support

Planning Permission Issues During a Dispute

Changes made during construction can sometimes affect planning compliance.

Examples might include:

  • Different windows
  • Increased dimensions
  • Changed roof forms
  • Altered external materials

If the completed work differs materially from the approved planning drawings, the position should be reviewed.

Depending on the circumstances, further planning action may be required.

Building Regulations Issues

A dispute may also involve work that does not appear to comply with the technical design or Building Regulations requirements.

Possible areas include:

  • Structure
  • Fire safety
  • Insulation
  • Ventilation
  • Drainage
  • Stairs
  • Glazing

Building Control involvement and inspection records can be important evidence.

 

Building Regulations

Missing Building Control Inspections

Problems can arise where required inspections were not arranged during construction.

This may make it more difficult to confirm work that is now concealed.

Depending on the situation, Building Control may request:

  • Additional evidence
  • Photographs
  • Calculations
  • Opening-up work
  • Further inspection

The appropriate response depends on what work has been completed.

Missing Certificates

At the end of a project, missing documentation can become another source of dispute.

This may include:

  • Electrical certification
  • Gas certification
  • Window documentation
  • Heating commissioning
  • Specialist guarantees

A list of outstanding documents can help clarify what still needs to be provided.

Recording the Condition of the Work

If a dispute is escalating, document the site carefully.

This can include:

  • Wide photographs
  • Close-up photographs
  • Dates
  • Notes
  • Drawing references
  • Measurements where relevant

Avoid relying entirely on memory.

A clear record can be useful whether the issue is eventually resolved informally or requires professional advice.

Keep Written Records

Important communication should be recorded.

Keep:

  • Emails
  • Quotes
  • Contracts
  • Drawings
  • Invoices
  • Payment records
  • Variation requests
  • Photographs
  • Messages
  • Meeting notes

If important discussions occur verbally, consider confirming the key points afterwards in writing.

Avoid Changing the Work Before It Is Recorded

If another contractor immediately removes or alters disputed work, it may become much harder to establish what originally existed.

Where practical, document concerns before remedial work begins.

For significant disputes, professional or legal advice may be appropriate before evidence is altered.

Try to Identify the Actual Issue

Construction disputes can become emotionally charged very quickly.

But the most useful question is often:

What specifically is disputed?

For example:

  • One unpaid invoice
  • One variation
  • One defective roof detail
  • Three weeks of delay
  • Missing work
  • - Unclear contract wording

Breaking the dispute into individual issues can make it easier to resolve.

Separate Technical Issues From Commercial Issues

A dispute may contain several different types of problem.

For example:

Technical issue:
Is the roof detail correct?

Commercial issue:
Who pays to change it?

Legal issue:
Who is contractually responsible?

These are related but not identical questions.

Tholos can assist with architectural and technical issues.

Contractual and legal disputes may require specialist legal advice.

Can a Builder Dispute Be Resolved Without Court?

Often, yes.

Many disputes are resolved through:

  • Direct discussion
  • Written clarification
  • Site meetings
  • Agreement on remedial work
  • Negotiation
  • Mediation

More formal procedures may be required where agreement cannot be reached.

The appropriate route depends on the contract and dispute.

Mediation

Mediation can allow both parties to discuss the dispute with an independent mediator.

The mediator does not normally impose a decision.
Instead, the aim is to help the parties reach their own agreement.

It can sometimes be a more proportionate approach than litigation.

Adjudication

Adjudication is a formal dispute-resolution process commonly used within construction.
Whether it is available and appropriate depends on the contractual and legal circumstances.
If adjudication is being considered, specialist legal advice should be sought.

Court Proceedings

Court proceedings may become necessary in some disputes.

However, litigation can involve:

  • Cost
  • Time
  • Evidence
  • Expert input

Before pursuing legal action, clients should obtain advice about their particular circumstances.

Tholos does not provide legal representation.

Expert Evidence

More serious disputes may require independent expert evidence.

An expert may be asked to consider matters such as:

  • Workmanship
  • Design
  • Defects
  • Compliance
  • Cost of remedial work

The role of a formal expert witness is different from ordinary architectural project support and may require a specifically appointed independent professional.

Builder dispute

Can Tholos Act as an Independent Expert?

That depends on the circumstances.
If Tholos designed or administered the original project, there may be limitations on acting as an independent expert in a formal dispute.

Where formal independent expert evidence is required, a separate suitably qualified professional may be more appropriate.

However, Tholos can still help explain the architectural information and project history where appropriate.

Builder Disputes on Projects Designed by Another Architect

Tholos may also be able to review projects originally designed by another practice.

This can include reviewing:

  • Existing drawings
  • Site condition
  • Scope
  • Technical issues

The level of involvement will depend on the information available and the nature of the dispute.

If You Are Thinking About Replacing the Builder

Replacing a contractor during construction can be complex.

Before another builder takes over, it is useful to establish:

  • Current site condition
  • Work completed
  • Work outstanding
  • Defects
  • aterials on site
  • Outstanding certificates
  • Temporary works

Contractual and legal issues should also be considered before terminating an existing appointment.

Getting Another Builder to Finish the Work

A replacement contractor will usually need enough information to understand:

  • What has already been built
  • What remains
  • What needs correction
  • What design should be followed

Incomplete or defective work can make pricing more difficult than starting a project from the beginning.

A clear schedule of remaining works can help.

Remedial Works

Where defects need correction, the solution should be properly considered.

Remedial work may require:

  • New drawings
  • Technical details
  • Structural input
  • Opening-up
  • Building Control discussion

Simply covering over a problem is not the same as resolving it.

How Tholos Can Help With a Builder Dispute

Depending on the project and the nature of the problem, Tholos may be able to help with:

  • Reviewing drawings
  • Reviewing quotations
  • Reviewing project scope
  • Comparing built work against drawings
  • Site inspections
  • Photographing and recording issues
  • Identifying incomplete work
  • Identifying areas requiring specialist input
  • Preparing architectural remedial information
  • Helping clarify technical issues
  • Supporting discussions between client and builder

Our role is focused on the architectural and technical side of the project.

Where the dispute involves legal interpretation, formal claims or contract termination, appropriate legal advice should also be obtained.

Frequently Asked Questions

What should I do if I have a dispute with my builder?

Start by gathering the contract, quotation, drawings, correspondence, payment records and photographs.

Identify the specific points in dispute rather than treating the entire project as one problem.

Professional or legal advice may then be appropriate depending on the issue.

Can an architect help with a builder dispute?

Yes, particularly where the dispute involves drawings, scope, workmanship, construction details, variations or incomplete work.

Legal interpretation should be handled by a legal professional.

What if the builder has not followed the drawings?

The work should first be compared against the correct construction drawings and revisions.

The significance of any difference then needs to be assessed.

What if I believe the work is defective?

Document the issue before it is altered.
Depending on the nature of the defect, an architect, structural engineer, surveyor or other specialist may need to inspect it.

Can I dismiss my builder and hire someone else?

Ending a construction contract can have legal and financial consequences.
Review the contract and obtain appropriate advice before terminating an appointment.

Get Clarity Before the Dispute Gets Worse

A construction dispute can quickly become more difficult when technical, financial and contractual issues become mixed together.

The first step is usually to create clarity.

Establish:

  • What was designed
  • What was agreed
  • What was built
  • What has been paid
  • What remains unresolved

From there, it becomes much easier to decide what action is appropriate.

At Tholos Architects, we can help review the architectural and technical side of a builder dispute and identify the information needed to move the project forward.
