Variations and cowboy contractors who don't face the costs

The Joint Contracts Tribunal (JCT) 2016 is a suite of standard construction contracts used in the UK. When it comes to variations, delays, and impacts on construction projects, the contract may include specific provisions. Here's a list of variations that could be in alignment with JCT 2016, considering delays and their impact:

  1. Change Order Request:Document detailing changes to the original contract scope that may impact the project schedule.
  2. Extension of Time (EOT) Request:Formal request for an extension to the project timeline due to unforeseen circumstances, as per JCT 2016 provisions.
  3. Delay Notice:Notification of any delays as soon as they are recognized, in accordance with the contract.
  4. Compensation Event Claim:A claim for compensation for additional costs incurred due to events specified in the contract as compensatable.
  5. Acceleration Agreement:An agreement between parties to accelerate the project schedule, possibly to recover time lost due to delays.
  6. Liquidated Damages Assessment:Calculation of liquidated damages, as specified in the contract, for delays attributable to the contractor.
  7. Revised Program Submission:Submission of an updated project schedule reflecting any approved changes or delays.
  8. Mitigation Plan:A plan outlining measures taken to mitigate the impact of delays on the project.
  9. Progress Reports:Regular reports detailing the current status of the project, including any delays and their effects on the schedule.
  10. Risk Assessment and Management Plan:Identification of potential risks impacting project timelines and a plan for managing or mitigating these risks.
  11. Request for Information (RFI):Formal request seeking additional information that may affect project timelines.
  12. Contingency Plan Approval:Approval of a plan for handling unexpected events or delays that could impact the project.
  13. Defects Liability Period Extension:Extension of the period during which the contractor is responsible for correcting defects due to delays in completion.
  14. Review of Delay Analysis:A formal review of the delay analysis was conducted by the parties involved to assess its validity and impact on the project.
  15. Expert Determination:Appointment of an independent expert to assess and determine the impact of delays on the project.
  16. Variations in a brickwork project under a Joint Contracts Tribunal (JCT) 2016 contract can arise due to various factors. Here's a list of common variations that may be encountered in alignment with the JCT 2016 provisions:

  1. Change in Brick Type or Colour: Request for a variation due to a change in the specified type or colour of bricks.
  2. Altered Brickwork Design: Modifications to the original brickwork design, including changes in patterns, textures, or layout.
  3. Additional Openings or Features: Requests for variations to accommodate additional doors, windows, archways, or other features in the brickwork.
  4. Alteration in Brick Bonding Pattern: Changes to the specified brick bonding pattern, such as switching from stretcher bond to Flemish bond.
  5. Adjustments to Mortar Mix: Variations related to alterations in the mortar mix, including changes in colour or composition.
  6. Installation of Brick Veneer: Request for variations to include or exclude brick veneer as part of the project.
  7. Integration of Architectural Features: Modifications to incorporate architectural features like corbelling, string courses, or decorative brickwork.
  8. Brickwork Expansion or Reduction: Changes in the overall scope of brickwork, either expanding or reducing the area covered.
  9. Substitute Materials: Requests for variations due to the need to substitute specified brick materials with alternatives.
  10. Adjustment in Pointing Style: Variations related to alterations in the style of pointing, such as flush, weather-struck, or recessed.
  11. Additional or Reduced Wall Thickness: Changes to the thickness of brick walls, either increasing or decreasing as per design requirements.
  12. Modifications for Structural Integrity: Variations necessary for reinforcing or altering brickwork to enhance structural integrity.
  13. Alignment Changes: Adjustments to the alignment of brick courses or walls due to design revisions or on-site considerations.
  14. Weather Protection Measures: Variations to incorporate additional weather protection measures, such as the application of sealants or coatings.
  15. Alterations for Accessibility: Requests for variations to ensure compliance with accessibility requirements, such as creating ramps or widened doorways within the brickwork.
  16. Incorporation of Damp Proofing Measures: Changes to include or modify damp proofing measures in the brickwork, if required.
  17. Brickwork Repairs: Variations for repairing damaged or defective brickwork, as discovered during construction.
  18. Additional Brickwork Testing: Requests for variations to conduct additional testing on the brickwork, such as structural or weather resistance tests.

It's important to refer to the specific terms and conditions outlined in the JCT 2016 contract and any amendments made to accurately address and document variations in the brickwork project. Additionally, communication and agreement processes as per the contract should be followed for each variation.


Effectively managing variations in a construction project requires a professional and systematic approach. First and foremost, clear communication is paramount. When a potential variation arises, it's crucial for all parties involved to promptly communicate the proposed change, its implications, and any anticipated impact on the project timeline or cost. This involves formal documentation detailing the nature of the variation, the reasons for the change, and the expected consequences.

Using standardised forms or templates, such as those provided in the Joint Contracts Tribunal (JCT) 2016 contract, helps maintain consistency and clarity in the communication process. Moreover, engaging in open and collaborative discussions with all stakeholders, including contractors, subcontractors, and project managers, fosters a transparent environment that facilitates a smoother resolution of variations.

Once a potential variation is identified and communicated, the next step is a thorough assessment. This involves evaluating the technical, financial, and scheduling implications of the proposed change. Project managers, quantity surveyors, and relevant technical experts should work collaboratively to analyse the impact on the project's scope, costs, and timeline. Utilising standardized processes, such as the valuation procedures outlined in the contract, helps ensure fairness and objectivity in assessing the value of the variation. Throughout this process, maintaining a focus on fair and equitable outcomes for all parties involved is essential to fostering positive professional relationships and minimising disputes.


Professionalism in dealing with variations involves adherence to contract provisions, transparent communication, and a commitment to finding mutually beneficial solutions that align with the project's objectives.

A lot of conflicting terminology there Glen which isn’t standard to JCT, such as Change Order Request which doesn’t feature ans is simply an “instruction” and Compensation Event which is from NEC. Hope it helps ??
