Stop-Work Orders: Document Site Halts on Your Gantt

What is a stop-work order in Thai construction, and why does it matter for your schedule?

A stop-work order is a formal instruction — from a building authority, the owner, or a force-majeure event — that halts all or part of a construction project until a defined condition is met. In Thailand, the most common triggers are a safety inspection that finds a serious hazard under the Building Control Act, an owner decision to pause the scope, or a natural event such as severe flooding or a heavy storm that makes the site unsafe to continue. Whatever the cause, the moment work stops the Gantt falls out of date: every downstream task that depended on the stopped work must shift forward. A contractor who does not update the schedule immediately has no clear picture of when the project can recover, no document trail to support an extension-of-time claim, and no way to show the owner a credible revised timeline. The cost of an unmanaged stoppage is almost always higher than the cost of documenting it correctly on day one.

What are the most common reasons a site gets stopped in Thailand?

Authority-ordered stops account for a significant share of site halts on Thai residential and small commercial projects. A local government inspector or the Department of Public Works can issue a stop-work notice if structural work is underway without an approved building permit, if safety equipment such as scaffolding guard rails is absent, or if construction is encroaching on a setback line. In 2026 Thailand's construction safety enforcement tightened following a series of high-profile incidents, so routine site visits by local engineers became more frequent than they were in earlier years. Beyond authority orders, owners occasionally issue their own pause instructions when they need time to approve a design change, resolve a financing gap, or await approval from a bank inspection. Flooding and monsoon-season storm damage complete the picture: a site in a low-lying area can lose a week or two to water damage and drying time even when the rain itself lasted only two days.

How do you record a stop-work order in the Gantt planning view?

As soon as the stop instruction is received, add a zero-duration milestone task to the Gantt planning view named "Site Stopped — [reason]" on the date the stop takes effect. Then extend all tasks that cannot proceed during the stoppage by the duration of the halt. In SiteBoard's Gantt planning view, drag the affected tasks forward to reflect the new start dates, update task dependencies to cascade the shift through the rest of the schedule, and mark the % complete of any stopped task as it stood at the moment work ceased. Create a second milestone named "Stop-Work Order Lifted" at the expected resumption date, linked to the first milestone with a duration equal to the expected stop period. If the actual resumption slips, update that second milestone in real time. This two-milestone approach creates a clean, timestamped record of the stoppage inside the same tool the owner already uses to follow the project, making extension-of-time requests straightforward rather than requiring separate correspondence.

A worked example: a 3.2 million baht shophouse in Bang Bon stopped by a safety inspector

Khun Surasak was three weeks into a sixteen-week, 3.2 million baht shophouse renovation in Bang Bon when a District Public Works inspector issued a seven-day stop-work notice after finding the third-floor scaffolding lacked the required toe boards and mid-rails. Surasak immediately opened SiteBoard, added a "Site Stopped — Scaffolding Safety Notice" milestone on the date of the notice, and pushed all remaining tasks forward by ten days — seven for the ordered stop plus three for scaffolding inspection and clearance. He then sent the owner a LINE message with the owner sharing link so they could see the revised timeline directly. The scaffolding subcontractor rectified the issue in four days; the inspector returned, cleared the site, and Surasak updated the "Stop-Work Order Lifted" milestone to the actual date. The five-day underrun against the ten-day buffer let him pull the project end date back from its revised position. The original seven-day notice, the revised Gantt, and the clearance date gave him a complete record for his extension-of-time request — approved without dispute.

How should you notify the owner when the site is stopped?

Send a written notice — a LINE message or email works equally well — on the same day the stop instruction arrives. State the date, the reason, the issuing authority or event, and an estimated resumption date based on what you know at that moment. Share the owner sharing link so the owner can see the updated Gantt without waiting for a scheduled progress meeting. Avoid verbal-only notification: if a dispute about extension of time arises later, the written message and the timestamped Gantt update together constitute the record that defines when the owner was informed and what the schedule impact was. An owner who learns about a two-week stoppage only at the next monthly meeting will be far more unsettled than one who received a written notice on day one with a clear recovery plan already visible in the schedule.

Does a stop-work order entitle the contractor to an extension of time?

It depends on who caused the stop. A force-majeure event — flooding, a severe storm, or an earthquake — typically entitles the contractor to an extension of time equal to the duration of the halt, with no delay penalty, provided the contractor gives timely written notice under the contract. An authority-ordered stop for a safety violation caused by the contractor — missing guard rails, unlicensed structural work — generally does not entitle the contractor to an extension and may expose them to a delay penalty for every day the project slips beyond the original end date. An owner-ordered pause is normally the owner's risk: the contractor is entitled to the additional time and, in most Thai contracts, to preliminaries costs for the period of suspension. Documenting the cause clearly in the Gantt milestone label is therefore not only an operational step but a contractual one — "Site Stopped — Flood Water Above Ground Floor" is a fundamentally different claim basis from "Site Stopped — Scaffolding Deficiency Notice."

How do you plan the recovery after the stop-work order is lifted?

Once the site reopens, review the Gantt for the three nearest critical-path tasks and confirm their start dates are still achievable with the crew and materials on hand. If the stop has pushed the project end date past the contractual completion date, assess whether any tasks can be fast-tracked by running them in parallel, or whether overtime on the critical path can compress the schedule. In SiteBoard's Gantt planning view, adjust task durations only where overtime is genuinely planned, not optimistically assumed. Add a note "Recovery Plan — Revised Baseline" on the date the stop is lifted so the Gantt history shows clearly where the recovery starts. As on-site progress updates come in from the crew, the % complete bars will show whether the recovery is holding. Share the revised Gantt with the owner through the sharing link so their expectations align with the new reality from day one of the resumed build.

FAQ: How long can a Thai building authority keep a construction site stopped?

A stop issued under the Building Control Act for a safety or permit violation has no fixed statutory maximum duration — the site remains stopped until the contractor rectifies the cited deficiency and receives clearance from the issuing authority. In practice, straightforward safety rectifications such as scaffolding improvements or permit corrections are cleared within three to fourteen days. More serious issues — structural work that must be demolished, or a project without any building permit — can remain stopped for months while the contractor regularises the paperwork. There is no automatic financial compensation from the authority for the delay. Your practical tool is speed: address the stated violation as quickly as possible, request the clearance inspection promptly, and document the clearance date in the Gantt the moment you receive it.

FAQ: What documentation should you keep during a stop-work period?

During a stop, keep a daily site diary entry even if no physical work is underway — record the weather, any site visits by the authority, correspondence received or sent, and any costs incurred to maintain the site such as security or temporary weatherproofing. In SiteBoard, log an on-site progress update each day the site is stopped, noting the continued halt and any developments: an inspector visit, scaffolding repair progress, flood-water level reading. These timestamped entries, together with photos of the site condition, form a contemporaneous record that is far more persuasive in an extension-of-time negotiation than a retrospective narrative written weeks later. Maintain copies of all written correspondence with the authority and the owner in a single folder so the full record is retrievable when the project resumes.

FAQ: Can the owner claim liquidated damages if a contractor-caused stop delays handover?

Yes — if the stop results from a contractor deficiency and the project completes beyond the contractual completion date, the owner can apply liquidated damages for the period of delay at whatever daily rate the contract specifies. The contractor's most effective protection is to resolve the cited deficiency faster than the buffer in the original schedule allows and to document that the recovery caught up the lost time. If the stop's duration plus the remaining completion time still falls within the contractual end date, no liquidated damages apply. Where delay genuinely cannot be avoided, early written notice and a credible recovery plan shared through the owner sharing link on the day the stop is issued is the evidence that demonstrates good faith — and gives the best basis for negotiating a formal extension of time rather than facing an automatic damages deduction at project close.
