A lower total is not automatically better value. Compare the work, materials and finishing included in each proposal first.
Compare the complete intervention
Request both direct costs and temporary provisions for each phase. Include additional removal and reinstatement when phasing otherwise appears cheaper than one coordinated intervention.
Align the scope
Use the same headings for preparation, demolition, structure, installations and finishes. Mark missing items and distinguish fixed prices from provisional allowances.
What the drawing needs to explain
Create a phase drawing with three colours: repair now, improve later and investigate first. Mark where phases meet, such as roof edges, service routes and finished floors.
Which trade-off matters?
A complete approach can improve coordination, while phased work spreads the budget. Compare which junctions would need reworking after a delay and which elements can be completed independently.
Questions for your own property
- Is the finish level equivalent?
- What is excluded?
- How are changes recorded?
