SELECTION / SCOPE / HANDOVER
Before choosing the equipment
Tell the contractor what is known about ground investigation and previous excavation. Ask whether digging is expected to be sufficient or whether breaking or ripping may be required.
What belongs in the quote
Agree how differing ground conditions will be identified and priced. Include wear-related commercial terms and handling of oversized material in the proposal.
Think about the surrounding work
Ask for the exact carrier and attachment combination. Mounting geometry, attachment mass, hydraulic requirements and the work material all affect suitability. A coupler or tool change can alter the machine configuration; compatibility and operating limits must come from the supplier and manufacturer documentation for that combination.
Three questions for your contractor
- What ground evidence supports bucket selection?
- When would breaking or ripping be needed?
- How are changed conditions priced?
Bring a useful project brief
Bring site photographs, access measurements, available drawings and a description of the finished result. Identify what is known about the ground and existing services, and distinguish confirmed information from assumptions. Ask for written inclusions, exclusions, change procedures and handover records before comparing totals.
