Day-to-day operating brief
What Drainlayer work looks like in practice
A drainlayer installs below-ground drainage to line, level and connection details while controlling excavation, shoring, contamination and interfaces with existing services. The contract should cover setting-out evidence, testing and work that becomes concealed.
Responsibilities reflected in the contract
Install drainage pipework and chambers to approved details.
Verify line, level, fall and connection information.
Follow excavation, shoring, service and access controls.
Prepare bedding and complete joints using specified materials.
Test drainage and record defects or remedial work.
Capture inspections, photographs and as-built information before backfill.
A realistic working scenario
An existing pipe crosses the designed run at the required invert. The drainlayer records levels and location, keeps the excavation safe and waits for an approved detail instead of forcing a connection or altering fall by eye.
