Start with the same four questions
What is the starting condition, what must change, what must remain and what counts as complete? Those questions apply to a backyard and a commercial development, even though the supporting information and people involved may differ.
Residential work often starts with access
Gateways, neighbouring properties, occupied homes and reinstatement can dominate a small project. Define protection of existing surfaces and who arranges spoil removal. Ask whether a single machine and operator can provide the complete scope or whether additional deliveries and handling are needed.
Commercial work adds coordination
Commercial preparation may interface with tenant access, deliveries, surveyors, utility contractors and follow-on trades. Set out work zones, coordination responsibilities and staged handovers. Include the records required by the project team before another contractor takes possession of the work area.
Compare acceptance requirements
Use the project’s specified levels, materials and testing requirements. The appropriate checks come from the project team and the applicable design, not from a generic price-per-area comparison. Clarify who arranges and pays for tests and what happens if work needs correction.
Put exclusions beside the price
Ask every bidder to identify disposal, imported material, temporary access, dewatering, testing, restoration and changed-condition procedures. Different totals may reflect different scopes. Compare the written assumptions before concluding that one contractor is cheaper.
