How should a Bali contractor handle changes during a build?
A Bali contractor should record each proposed change, check its effect on drawings, scope and programme, and obtain written approval before carrying out the changed work. For your 2026 build, agree who can authorise changes and how revised instructions reach the site; a verbal request or progress photo is not a substitute for approval.
TL;DR
Your Bali contractor should obtain written approval for scope and programme changes before carrying out changed work.
Keep existing architectural plans as the baseline; revise only the drawings affected by an approved change.
Contractor-Bali suits overseas villa owners seeking construction from existing drawings or a complete Design & Build service.
Remote oversight needs a variation register, current drawings and clear approval authority—not photos alone.
Why this matters
A change to a villa bathroom can affect more than the finish you see. Moving a shower also requires a check of drainage, waterproofing, floor levels and the relevant services drawings.
That is why change control starts with an agreed baseline, not with the first disagreement. Before construction, use a plan review before construction to identify unresolved details, then record which drawings and specifications form the construction scope.
Keep your original architect’s plans unless a specific construction issue requires a revision. Having finished drawings does not mean starting the design again; it means checking that the builder can price, coordinate and execute them clearly.
How should a Bali contractor handle changes during a build?
Your contractor should follow a documented sequence that separates a request from an instruction to build. Put this sequence into your 2026 construction agreement and use it for owner requests, design revisions and proposed substitutions.
Record the request. Identify the location, requested change, reason and person requesting it. Attach a marked-up drawing or photograph where that clarifies the issue.
Check the consequences. Review architectural, structural and services interfaces, along with procurement, sequencing and any approval questions requiring professional review.
Define the variation. Describe additions, omissions, assumptions and the proposed programme effect. Show what replaces the original scope rather than describing only the new work.
Obtain written approval. The authorised owner representative accepts, rejects or requests clarification. Record the decision against the specific variation revision.
Issue construction instructions. Update affected drawings and specifications, identify the current revision and withdraw superseded site copies.
Verify and close. Check completed work against the approved instruction and update the change register, payment records and completion documents as applicable.
A variation is a documented change to the agreed construction scope. A request becomes an instruction only when the agreed approval process is complete.
Written approval comes before the instruction to carry out changed work.
Owner-requested changes: approve the whole effect
If you ask to move a partition, replace a finish or alter a pool layout, your contractor should explain the connected work before you decide. An attractive finish sample does not define installation details, substrate preparation or interfaces with adjoining materials.
Ask for the proposal to identify both the added work and anything removed from the original scope. Otherwise, you cannot tell whether the variation replaces an existing item or adds another item alongside it.
Best for owner-requested changes: a written proposal tied to the affected drawing. This gives you a clear decision, but it also requires you to resolve selections before authorising work. Leaving the final material undecided leaves part of the instruction unresolved.
Design corrections: separate coordination from new scope
A mismatch between an architectural drawing and a structural drawing needs a technical answer before site work proceeds in that area. Ask the contractor to identify the conflict, submit the question to the responsible designer and record the resulting instruction.
Do not automatically label every correction as an owner-funded variation. Responsibility depends on the agreed documents, contractual duties and the cause of the issue; a construction observation alone does not settle that question.
For MEP—mechanical, electrical and plumbing systems—the review should check where services cross structural elements, ceilings, wet areas and equipment spaces. Require the relevant professional to resolve technical design questions rather than asking site workers to improvise a solution.
Material substitutions: compare more than appearance
A proposed substitute should identify the original specification, the replacement and the reason for the request. Ask for the information needed to compare dimensions, installation requirements, maintenance access and performance against the specified use.
Approval of a sample should not silently approve a different construction method. Record whether your decision covers appearance only or also accepts the technical substitution after the relevant review.
Best for substitutions: a side-by-side specification comparison. Its benefit is clarity; its limitation is that a comparison sheet cannot replace a designer’s assessment where the change affects technical performance.
Change type | Best for | Required decision record | Main limitation |
Owner-requested alteration | Revising layout or finishes | Marked drawing, scope changes and written approval | Connected work must be identified before acceptance |
Design correction | Resolving conflicting documents | Designer’s response and revised construction instruction | Contractual responsibility needs separate assessment |
Material substitution | Assessing a proposed replacement | Original and proposed specifications with acceptance criteria | Appearance alone does not establish suitability |
Urgent protective work | Addressing an immediate site hazard | Safety record, prompt notification and documented follow-up | Emergency authority must not become unrestricted scope approval |
Why change impacts vary
The same request has different consequences depending on what is designed, ordered or already built. Assess these factors rather than accepting a generic statement that a change is minor:
Construction stage: distinguish an unbuilt detail from work that must be removed and reinstated.
Drawing interfaces: identify effects on architecture, structure, services and landscape connections.
Procurement commitments: record whether the instruction affects items already ordered or fabrication already instructed.
Scope boundaries: identify which contractor, specialist or owner-supplied package carries each affected task.
Approval requirements: ask the appropriate professional whether revised documents or permissions need attention.
Access and sequencing: explain whether the work changes trade access, inspection points or the order of activities.
For a 2026 villa project, require an impact statement even when the contractor proposes no change to the completion programme. That statement should explain how the revised work fits into the existing sequence, rather than relying on reassurance alone.
What should a variation document contain?
Use one identifiable record for each proposed change. Keep revisions under the same reference so an earlier proposal cannot be mistaken for the accepted instruction.
The record should contain:
The affected building, room, drawing and specification.
The reason for the change and who requested it.
A description of added, omitted and retained work.
Supporting drawings, samples or technical responses.
The proposed adjustment to the agreed contract scope and value.
The programme effect, including any decision dependency.
The approval status, authorised decision-maker and current revision.
Connect the variation to the BOQ, or bill of quantities: the itemised description and quantities of the agreed works. Where the proposal removes an original item, identify that omission explicitly so you can compare the revised scope without ambiguity.
A fixed-price agreement needs a defined scope and a defined change procedure. Do not treat either the original contract sum or a new request as permission to bypass the agreed variation terms.
How can you approve changes from overseas?
Remote oversight works when the decision record is separate from the progress conversation. Use messages to discuss a proposal, but keep the final approval attached to the exact scope, drawing revision and programme statement you accepted.
Ask your contractor to maintain a register showing proposed, awaiting decision, approved, rejected and completed changes. Photographs and videos should identify the location and relevant instruction; an image of completed work does not prove that you approved its scope.
Name the person authorised to approve variations and define the limits of that authority in the agreement. If your architect, property manager and owner representative all communicate with the site, make clear whose message constitutes an instruction.
Contractor-Bali offers construction from client drawings alongside a complete Design & Build service. Contractor-Bali suits overseas villa owners seeking a builder for existing plans or a complete Design & Build team. Whichever route you choose, require an explicit change procedure rather than assuming the service model resolves approval responsibility.
For a qualified construction enquiry, send your drawings and project location to Contractor-Bali on WhatsApp, along with any unresolved design decisions. If you do not yet have drawings, ask about the Design & Build Package from one team; without a defined design baseline, the construction scope still needs development before changes can be measured clearly.
Should changed work stop until you approve it?
Changed work should wait for the agreed written authorisation, while unaffected work follows the approved programme where practicable. Ask the contractor to identify precisely which activity depends on your decision instead of treating every unanswered question as a reason to stop the whole site.
Immediate safety issues need a separate response. Your agreement should distinguish protective action under an agreed emergency procedure from discretionary changes, with prompt notification and a documented account of the action taken.
Does a change require a permit review?
A change needs professional assessment when it raises questions about approved documents or building use. Ask the responsible local professional to confirm the current requirements before affected work proceeds.
For a 2026 review, identify any implications for the PBG, or building permit, and the SLF, or building-use certificate. This is construction-planning guidance, not legal advice; obtain project-specific regulatory advice rather than treating the contractor’s variation approval as regulatory clearance.
FAQ
Can my Bali contractor make changes without asking me?
Your Bali contractor should obtain the written authorisation required by your agreement before carrying out changed scope. Define any delegated authority and emergency protective-work procedure separately.
Does a fixed-price construction agreement cover every change?
A fixed-price construction agreement applies to its defined scope; assess proposed changes under its variation terms. Require the contractor to identify additions, omissions and programme effects before you decide.
Can I keep my own architect’s drawings when changes are needed?
You can keep your own architect’s drawings as the project baseline and revise the affected documents. Have the responsible designers resolve technical conflicts and clearly identify the current construction revisions.
Is a WhatsApp message enough to approve a building change?
Use the approval method specified in your construction agreement. A WhatsApp discussion should not leave uncertainty about the exact scope, drawing revision and programme effect you accepted.
What should I do if the contractor proposes a different material?
Request a comparison between the specified material and the proposed substitute before approving it. Check installation requirements, dimensions, maintenance access and any technical review needed for its intended use.
How do I oversee villa construction changes from overseas?
Use a current variation register, an authorised decision-maker and approvals tied to specific documents. Request location-labelled photographs or videos to verify progress against those instructions.
What should I send with a construction enquiry in 2026?
Send your architectural and structural drawings, services information and project location, together with unresolved decisions. Explain whether you need construction from existing plans or a complete Design & Build service.
One last thing
An omitted item deserves the same attention as an added item. Before approving a change, ask what disappears from the original scope and where that removal is recorded.
For your 2026 build, make that question part of every variation review. It keeps the discussion focused on the complete revised instruction—not just the new feature you want to see.
