Dear ###

We write further to your request, received 5 November 2025, which states:

"All responses are to cover from November 2015 to November 2025 and should be broken down to at least an annual total. If more granular data (quarterly / monthly etc) is available this will be acceptable.

Exclude work that the Government carries out "it self" from this information unless the work is is carried out by a private sector contractor. Information is only required on the private sector.

Temporary Traffic Regulation Notice will be referred to as TTRN

The number of TTRN applications relating to building work split into planned work and for emergency work (for instance the Finch road closure for drainage work relating to the Church)

The number of TTRN declined in the form of a summary table of the reasons for being declined (summary in this case means declined reason and total numbers)

The number of TTRN extensions received more than 14 days before existing closure (broken down into approved and denied)

The number of TTRN extensions received between 14 days and existing closure (broken down into approved and denied)

The number of TTRN extensions received after existing closure (broken down into approved and denied)

The number of TTRN per company (I know you will be aware but just a reminder that company names are not covered by GDPR so can be disclosed)

The number of complaints or queries received.

If at this point you want to include complaint or query data on Government work please feel free to but detail it separately.

Summary of complaint / queries or investigation by category (examples but not limited to - The number correspondence, correspondence not within time scales, restrict required access, etc etc)

The number of TTRN rescinded or not renewed due to a complaint / query or investigation

The number of complaints / queries or investigations per company"

While our aim is to provide information whenever possible, in this instance the public authority does not hold or cannot, after taking reasonable steps to do so, find some of the information that you have requested. The TTRN tracker is used only to monitor live applications. Once an application is refused or cancelled, it is removed from the tracker, and no record is retained of the number of refusals or the reasons for them.

Although applications include basic dates (such as the date submitted and proposed start date), the Department does not record or report this data in the specific format requested, including whether applications were made within or outside 14 days of a closure expiry.

The Department also does not record applications by company, nor does it record complaints by application or by complaint type. Therefore, this information cannot be provided as it is not held.

I have detailed below the information that is held.

The Department only retains this information for two years. Therefore, the answers provided are for 2024 and 2025 only.

In 2024 (1/1 – 31/12) there were 243 applications for planned works. In 2025 (1/1 to 13/11) there were 312 applications for planned work. In 2024 there were 32 applications for emergency work. In 2025 (to 13/11) there were 66 applications for emergency work.

In 2024 there were 40 extension applications applied after existing closure. In 2025 there were 35.
