Read The Landscape Package By Scope
Start by sorting the bid documents into work buckets:
- Planting
- Irrigation
- Hardscape
- Soil preparation
- Grading and drainage
- Site furnishings
- Demolition
- Maintenance or establishment period
- Warranty obligations
- Submittals and closeout
This keeps the takeoff organized and makes subcontractor or supplier quote review easier.
Verify Planting Requirements
Planting scope usually depends on schedules and notes spread across plans and specifications.
Check:
- Species and variety
- Size, caliper, or container requirement
- Quantity and spacing
- Root barrier, staking, mulch, and soil amendments
- Substitution rules
- Delivery and inspection requirements
- Seasonal installation limits
- Replacement or warranty terms
Confirm plant availability before bid day when the schedule includes specific species or sizes.
Review Irrigation Scope
Irrigation scope can create bid gaps when drawings show layout but specifications define performance, testing, and controls.
Review:
- Mainline and lateral pipe
- Sleeves under paving
- Heads, emitters, valves, and controllers
- Water-source connection
- Backflow requirements
- Power or communication needs
- Winterization or startup
- Testing and commissioning
If the water source or controller location is unclear, submit an RFI before pricing assumptions become expensive.
Level Hardscape And Site Work
Landscape contractors often touch hardscape and site preparation even when another trade owns major civil work.
Confirm:
- Pavers, stone, concrete, edging, and walls
- Base preparation and compaction
- Site furnishings
- Tree grates, guards, bollards, and bike racks
- Drainage tie-ins
- Demolition and disposal
- Import or export material
- Access and staging limits
Use the construction bid review checklist to catch form, addenda, and scope requirements before submission.
Price Maintenance And Establishment
Public landscaping projects may require maintenance after installation.
Look for:
- Watering frequency
- Mowing or pruning
- Weed control
- Fertilization
- Replacement requirements
- Final acceptance conditions
- Site visit logs
- Owner training
If maintenance is required, show how it is carried in the estimate and confirm whether it belongs in the base bid or an alternate.
Submission Checklist
Before the bid is submitted, confirm:
- Addenda are acknowledged
- Plant schedule matches the takeoff
- Irrigation scope matches the drawings and specifications
- Alternates are priced in the required format
- Maintenance scope is included or qualified
- Licenses, bonds, insurance, and forms are complete
- Supplier quotes are current
- Exclusions are clear and allowed
The best landscape bids are easy for the owner to evaluate because the scope, quantities, alternates, and assumptions are organized.
