SELECTION / SCOPE / HANDOVER
Before choosing the equipment
Describe the trench, footing or bulk excavation and its finish requirements. Ask the contractor to explain bucket width and profile in relation to the machine and the material being removed.
What belongs in the quote
Include alternative attachments where mixed conditions are expected. Agree how over-excavation, trimming and any required material separation are treated in the quote.
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
- Why does this bucket fit the profile?
- What happens if harder material is found?
- Who is responsible for final trimming?
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.
