How to Read This Tender
- 1This tender is split into three 'lots' — you can bid for all three or just the ones you're equipped for. Check the full tender documents to see if lots can be bid separately or must be bid together.
- 2The scope for hard landscaping and kerb modifications is marked as 'still under development' — this is a red flag. Request clarification on exact specifications, measurements, and materials before submitting your bid, as vague scope = cost overrun risk.
- 3The soft landscaping work involves working at height on steep slopes near live hazards (traffic, fire systems). You'll need robust health and safety plans and likely specialist equipment — factor this into your costs and timeline.
- 4The buyer mentions providing a 'GA' (General Arrangement drawing) for soft landscaping — request all drawings, specifications, and technical documents early. These are crucial for accurate pricing.
- 5Look in the full tender documents for: timescales and weather restrictions (slope work in winter may be difficult), insurance requirements, environmental regulations, utility location maps, and any pre-mobilisation site visits you should attend.
Tips for Small Businesses
- Lot 2 (soft landscaping) and Lot 3 (kerb/edge protection) might be good subcontracting opportunities if you're strong in one area but weak in another — find a specialist partner to co-bid or offer to supply labour for a larger contractor's bid.
- The irrigation system design and installation is a discrete specialist task — if you're not an irrigation expert, partner with or subcontract to a landscape engineer. This could be a differentiator in your bid quality.
- Push hard for detailed scope and drawings before submitting. The 'scope still under development' comment suggests the buyer hasn't fully spec'd the work — ask specific questions in writing and get answers in writing. This protects you if scope creeps mid-contract.
