When a construction project starts to feel more like a battlefield than a building site, it can leave everyone frustrated and unsure of what comes next. Payment delays, disagreements about what was agreed to, or unexpected changes can quickly turn a smooth project into a stressful one. This is where adjudication often becomes the fast and effective way forward. It provides a clear path to resolution without halting the entire project.
This article breaks down the most common disputes resolved through adjudication in a casual and practical way so the everyday reader can understand how these issues unfold and why adjudication remains a relied upon tool across the construction industry.
Why Do Payment Disputes End Up in Adjudication?
Payment disagreements are one of the most frequent reasons parties turn to adjudication. When invoices remain unsettled or payments are partially made, cash flow takes an immediate hit. This is especially common when disputes arise about valuation of completed work, variations, or progress claim calculations. Many contractors and subcontractors use adjudication because it offers a fast and enforceable determination that can keep projects moving.
Payment disputes often include
• Underpayment concerns
• Delayed progress claim responses
• Disputes between payment claims and payment schedules
• Retention money not released
• Non payment for variations
Adjudication gives parties an avenue to resolve payment issues through a statutory process that is binding on an interim basis and helps support project continuity.
What Makes Variation Disputes So Common?
Any deviation from the original scope can trigger disagreement. Variations are common in construction, but agreeing on the value of additional work is not always straightforward. This often leads to disagreements between principals, contractors, and subcontractors about entitlement and valuation.
Typical variation disputes involve
• Changes in scope of work
• Differences in interpretation of contract clauses
• Disputes about whether extra work was instructed
• Disagreement on the correct quantum to apply
Adjudicators are frequently called upon to review documentation, emails, drawings, and instructions to determine the appropriate outcome. Their assessment is evidence based and focuses on contractual clarity and procedural fairness.
Why Do Delay and Time Extension Claims Require Adjudication?
Construction delays are almost inevitable. Weather, material shortages, labour issues, and design changes can all push out timelines. The challenge arises when the parties cannot agree on who is responsible for the delay or how long the extension should be.
Delay disputes often relate to
• Extension of time entitlements
• Disruption claims
• Allegations of acceleration
• Disputes about liquidated damages
• Program impacts from variations
Adjudicators examine the evidence presented, including programs, site diaries, communications, and contractual obligations. Their determination helps establish responsibility and entitlement, which allows the project to proceed with certainty.
How Do Defective Work Claims Lead to Adjudication?
Defective or incomplete work is another common dispute. It affects project progress, quality, and valuation. When the parties disagree about whether the work meets the required standard or how much rectification will cost, adjudication becomes a straightforward resolution pathway.
Defective work disputes may include
• Workmanship concerns
• Non compliance with specifications
• Alleged breaches of contractual quality
• Disagreements about valuation of rectification work
Adjudicators rely on photographic evidence, expert assessments, and contractual documents to determine outcomes that are enforceable and transparent.
Which Valuation Disputes Commonly Require Adjudication?
Even when there is no disagreement about what work has been completed, valuation becomes a frequent point of conflict. When parties disagree on how much the work is worth, an adjudicator can step in and provide an impartial assessment.
Valuation disputes often involve
• Quantum calculations
• Conflicting assessments by quantity surveyors
• Disputes about milestone or progress valuations
• Differences in industry accepted rates
Adjudication provides quick clarity which is essential for maintaining momentum and cash flow.
