In brief
- A kerb sets the line and level that roadside drainage depends on, so an alignment error shows up later as ponding or a blocked channel.
- Certificates and attendance sheets record time in a room, not whether a trainee can pull a string line, set a fall and check levels on site.
- Ask for a supervised on-site assessment: string line set, levels taken, joints checked, and a short post-course task observed by a supervisor.

Kerb alignment training gaps in Hargeisa matter because a kerb is not just an edge. It sets the line and level that roadside drainage follows. Attendance on a course shows a trainee was present. It does not show whether that trainee can pull a string line, set a fall and hold a channel line on a working street.
What does kerb alignment training actually have to deliver?
It has to produce a person who can set out and build a kerb line that drains.
A kerb unit sits on a bed, set to a line and a level. The critical numbers are the line along the street, the level at the top of the unit, and the fall along the channel so water runs to a gully or outfall instead of standing. On a straight run, a string line and a level give both. On a curve or at a junction, the setter has to keep the line true and still hold the fall, which takes practice with the tools, not listening to a lecture.
The practical skills are narrow and checkable: drive or set pegs on the correct line, transfer a level from a known point, bed and tap a unit down without breaking the bed, check line and level with a straight edge, and leave joints that do not step. General practice is to check line and level at every unit or at close intervals, then confirm against the project specification and the engineer's setting-out drawing. Ask the training provider what a graduate should be able to do on the first day on site.
Why can a certificate hide a weak setter?
Because written tests and attendance sheets do not measure the hand skills that decide whether the channel drains.
A classroom course can teach terminology, units, safety and drawing reading, and a multiple-choice test can confirm recall. It cannot show whether a trainee can see that a unit is two millimetres proud and correct it, or whether the trainee knows to check the channel fall before bedding a long run. In practice, assessment often stops at the test, and the certificate then stands in for a competency nobody observed.
The risk lands on the work. A run set slightly high at the low end holds water and silt; a run set with a reverse fall pushes water the wrong way; a stepped joint catches grit and sheds the mortar around it. Ground and runoff conditions vary from street to street, so have them checked against the project's own survey and specification before the line is set. What a supervisor can rely on is the setting-out drawing, the specified fall and a check of the built line before the channel is finished.
How do you test the skill before it reaches the street?
Set one observed task on a real kerb line and record what the trainee does.
The task is simple to run: give the trainee a setting-out drawing, pegs, a string line and a level; ask for a marked line, an agreed fall and three units bedded and checked. Watch the sequence. A competent setter checks the reference level first, sets the line before bedding, checks each unit, and corrects a unit instead of leaving it. Ask why the fall was chosen and what happens at the low end. Record the result, not just the pass.
For employers, the same logic applies to hiring. Ask to walk a recent site and see finished kerb runs after rain, and ask what checking routine was used on the line. For providers, build the assessment around line, level, fall and joints, and keep the record with the certificate. Confirm any specification limit, such as a permitted step or a required fall, against the project's documents and the engineer, not against a rule of thumb.
What to do next
Before the next kerb run starts, give the nominated setter one observed task on a short trial length: string line, levels, fall and three bedded units. Record the outcome and file it with the course certificate. If the trainee cannot hold line and level, arrange supervised practice on that trial length before the street work begins.
Frequently asked questions
Does a kerb alignment certificate prove a worker can set out a kerb line?
No. A certificate records that the worker attended and passed the course test. Ask the provider for the practical assessment record showing a set line, levels taken and units checked, or run a short observed task yourself.
What settles a kerb alignment dispute on site?
The setting-out drawing, the recorded levels along the built line and the specified fall. Measure the finished channel after rain, compare it with the drawing, and check what the contract says about inspection and acceptance, since the drawing and recorded levels are the basis for resolving the dispute.
