Use LTA.PROMPT to register and submit your application under the correct applicant category, whether you are a Professional Engineer, an authorized agency officer, a registered contractor, or a site supervisor, before any street works begin. LTA.PROMPT is the portal for applications and notifications to land-managing agencies for work on public streets. Where the works involve lane occupation, prepare a Traffic Control Plan before you submit.
TL;DR:
- Applications for street works permits must be submitted well in advance, with lane occupation requests requiring at least 10 working days’ lead time.
- Key submission documents include detailed site plans, photographs, work method statements, Traffic Control Plans, and cadastral plans for works on state land.
- Registration categories for applicants, such as Professional Engineers or contractors, demand specific evidence like active credentials, proper authorization, and experience, which should be verified early.
- Approval timing can be delayed if multiple agencies like PUB, SLA, or NParks are involved, especially for projects spanning different jurisdictions.
- Common causes of application rejection include incomplete or inconsistent plans, missing documents, or mismatched authorization letters, all of which are easily fixed with proper review before submission.

What a street works permit covers under Singapore law
Street works in Singapore fall under the Street Works (Works on Public Streets) Regulations, alongside the Street Works (Street Works by Private Persons) Regulations. These regulations set out what counts as street works, the fees that apply, and the Land Transport Authority’s inspection powers once works are underway.
A permit or notification is typically triggered by excavation, soil investigation boring, crane parking or hoisting over a public street, lane occupation, or temporary deposits of materials or equipment on the road reserve. Each of these activities carries different documentation and approval paths, so the first step is identifying exactly which category your works fall under before you open a PROMPT application.
The approving agency also depends on location. Works on a road carriageway, footpath, or side table generally sit with the Land Transport Authority (LTA), while drains and backlanes may involve the Public Utilities Board (PUB). Works touching vacant state land often require clearance from the Singapore Land Authority (SLA), and projects within Jurong industrial estates may need sign-off from the Jurong Town Corporation (JTC). Car parks and green verges can bring the Housing & Development Board (HDB) or National Parks Board (NParks) into the approval chain. Mapping your site against these boundaries early avoids a rejected application weeks into your program.
Who can apply: registration categories on LTA.PROMPT
LTA.PROMPT assigns applicants to defined categories, and each one carries its own evidence requirements. A Professional Engineer applying under the PE category needs an active PE registration and a current practising certificate on file. An agency or department officer applying on behalf of a public body needs a letter of authorization confirming they can act for that agency. Contractors and site supervisors are assessed against competency criteria, which commonly means holding CITI certification or demonstrating equivalent hands-on experience in street works supervision.
A few habits separate smooth registrations from stalled ones:
- Start the registration process well before your target submission date, since category verification takes time.
- Attach authorization letters and scanned documents that are legible and complete on first upload.
- Follow LTA’s recommended file-size guidance so uploads do not fail midway through submission.
Getting the applicant category wrong, or submitting on behalf of a PE without the right endorsement, is one of the more common reasons applications bounce back at the first review stage.
Documents and plans you need before you submit
The LTA requirements for street work proposals set out the core document package every applicant should assemble ahead of time. Missing or mismatched documents are the most frequent cause of back-and-forth with reviewers, so treat this as a checklist rather than a guideline.
- A location or site plan showing the exact extent of proposed works relative to road features.
- Photographs of existing ground conditions at the site before works begin.
- A written work method statement describing sequence, equipment, and safety measures.
- Photographs or a schematic diagram of existing road markings in the affected area.
- A Traffic Control Plan, where any lane occupation is involved.
- A cadastral plan, where the works affect state land.
Applicants should also hold a public liability insurance policy naming LTA as principal, where the nature of works requires it, along with workmen’s compensation coverage for site personnel, as referenced in LTA’s PROMPT FAQ.
Drawings should be prepared to a legible, consistent scale, with the proposed occupation area clearly marked against existing road features, not just described in text. Reviewers compare your site plan against your Traffic Control Plan line by line, so inconsistencies between the two documents slow everything down.
Pro Tip: Split large attachments into several files under 1MB each rather than one bulky PDF; it reduces portal timeouts and avoids resubmission cycles caused by failed uploads.
Timelines, fees, and charge rules you should plan around
Processing speed depends heavily on whether your works involve lane occupation. According to LTA.PROMPT’s FAQ on road closure notifications, applications involving lane occupation require submission at least 10 working days in advance, and processing is typically completed within around 10 working days where specified. Building your program around these windows, rather than around your preferred start date, is what keeps a schedule realistic.
Processing is typically completed within about 10 working days for lane occupation applications submitted with the required lead time, which means late submissions push your start date back by the same margin, not just by the delay itself.
Fee structures generally fall into two types:
- Application processing fees, which are charged regardless of outcome and are not refundable.
- Daily occupation charges tied to how long you hold the street or lane, which may be refunded if you cancel before the approved period begins.
Where your works touch more than one agency’s jurisdiction, build in extra time for inter-agency checks. A permit that looks straightforward on LTA’s side can still wait on a parallel PUB or SLA clearance.
When to seek pre-consultation beyond LTA.PROMPT
LTA.PROMPT manages permits and notifications, but it does not replace planning approvals. Projects that trigger building or fire safety requirements still need prior approval from URA, BCA, or SCDF before a street works application makes sense, and submitting to PROMPT first, without those approvals in hand, usually wastes a submission cycle.
Certain projects call for pre-consultation well before any PROMPT submission:
- Major utility diversion proposals affecting multiple services in one corridor.
- Works requiring adoption under a Master Plan Committee process.
- Deep excavation works near existing structures or utilities.
- Tunnelling works, which typically warrant a lead time of around six months for in-principle consultation.
The most common failure modes we see are incomplete Traffic Control Plans, site plans that do not clearly show the proposed occupation, and authorization letters that do not match the applicant category on record. We support project teams through document review, PE endorsement, and direct liaison with the relevant approving agency to close these gaps before submission, which is the same groundwork covered in our guide on key steps for LTA approval.
Pro Tip: If your project touches more than one land-managing agency, confirm each agency’s documentation requirements before you draft a single plan, rather than adapting one agency’s package after the fact.
A practical checklist before you hit submit
A short pre-submission routine catches most of the errors that cause delays. In the week before submission, confirm that your applicant registration and PE endorsement are active, that every file is labeled and matched to the correct checklist item, that your insurance wording names LTA as principal where required, and that attachments are compressed to meet upload limits. On the day of submission, do a final check that the nominated PE’s details match what is on file with LTA.
- Confirm applicant category registration and PE practising certificate status.
- Match every attached file to its checklist item and rename files clearly.
- Verify insurance documents name LTA as principal where the works require it.
- Compress and split large attachments before uploading.
- Cross-check the nominated PE’s name and registration number against PROMPT records.
The most frequent rejection causes are an incomplete or inconsistent Traffic Control Plan, a missing cadastral plan on state land projects, and authorization letters that do not match the registered applicant category. Each of these is fixable by resubmitting the corrected document rather than restarting the whole application, which is why a careful first pass matters more than a fast one.
If circumstances change after approval, you can request a variation or cancellation through PROMPT. Daily occupation charges tied to an unused approved period may be refunded on cancellation, though processing fees already paid are not.
Pro Tip: Keep a dated record of every document version submitted; when an amendment is requested, reviewers often ask which version introduced the change.
A practitioner’s view on what actually slows permits down
Most of the delays we see on site have nothing to do with the works themselves and everything to do with paperwork that was assembled too quickly. The pattern repeats: a Traffic Control Plan drafted without checking the site plan against it, or a contractor applying under the wrong category because no one confirmed who the nominated PE would be. Bringing in a Qualified Person early, before the application is drafted, consistently shortens the review cycle more than any other single step.

FAQ
How do I get a permit to work on public streets?
Register on LTA.PROMPT under the applicant category that matches your role, whether Professional Engineer, agency officer, contractor, or site supervisor, then submit your site plan, work method statement, and supporting documents through the portal. Where lane occupation is involved, a Traffic Control Plan must accompany the application.
What are the new rules for work permits in Singapore in 2026?
Street works permits continue to operate under the Street Works (Works on Public Streets) Regulations and related amendments recorded on Singapore Statutes Online, which applicants should check for the current fee schedule and terminology within the existing regulatory framework and LTA.PROMPT process.
How much does it cost to have a road closed by LTA?
Costs are made up of an application processing fee, which is non-refundable, and daily occupation charges that apply for the period the street or lane is held. Processing fees and charge structures are confirmed at the point of application through LTA.PROMPT, since they depend on the scope and duration of works.
What are the different types of work permits in Singapore for street works?
Street works applications on LTA.PROMPT generally cover permits for excavation, soil investigation, lane occupation with a Traffic Control Plan, and road closure notifications under Section 115, each with its own document requirements. The correct type depends on the activity and location, with separate notification paths for different land-managing agencies such as LTA, PUB, JTC, HDB, NParks, and SLA.
