Short-duration works involve a single vehicle or a small number of vehicles undertaking one or more intermittent stops of:
up to 15 minutes – could be used for activities such as street light maintenance, pole testing, road markings, compliance testing, jetting of sewers, jet or velocity patching, etc; or
between 15 and 60 minutes (between 15 and 30 minutes in Scotland) – could be used for activities such as pothole repairs, leak detection, fault finding, tree cutting or felling, installation of traffic loops, coring. This time period must include all time needed to set up and dismantle signing, lighting and guarding.
Works involving stops that are expected to last more than 60 minutes (30 minutes in Scotland) must have the signing and guarding as for a fixed site. The estimate of the time taken to complete a specific task should include an allowance for work not going smoothly. If works overrun significantly, you must review your risk assessment and consider whether to revert to the requirements for a fixed site or to proceed as quickly as possible to clear the road.
Caution: Mobile and short-duration static works should only be carried out when there is good visibility and during periods of low risk. Consult your supervisor, manager or other competent person if work is to take place in the centre of the carriageway with traffic passing on both sides.
