10 certificates

Street works certificates

Everyone holds LA. Operatives add the O units for the work they do; supervisors add the S units for the work they monitor.

Required by everyone

Held by operatives and supervisors alike. If this certificate expires, every other street-works certificate you hold is invalid.

Operative units

Held by the people carrying out the work. Each O unit also depends on LA and O1 remaining valid.

O1

Signing, Lighting & Guarding

Operatives. O1 is a key certificate — every other O unit depends on it.

Setting out a works site so traffic and pedestrians stay safe: the survey and risk assessment before you start, safety zones and layout, provision for pedestrians and vulnerable users, and the forms of traffic control.

Excavation in the Highway

Operatives who break ground.

Opening the highway: recognising the road and footway structure you are cutting through, excavation methods, working safely around other apparatus and in high-risk areas, and handling excavated material.

Supervisor units

Held by the people supervising the work. Each S unit also depends on LA and S1 remaining valid.

Key certificates

Three certificates carry the others. LA underpins everything — if it expires, every street works certificate you hold is invalid. O1 does the same for the other operative units, and S1 for the other supervisor units. Renew a key certificate late and the units depending on it lapse with it, so it is worth knowing which of yours is the earliest to expire.

Revise only the certificates you hold

The app asks which certificates you hold the first time you open it, then hides every topic that belongs to a unit you do not.
