01 / Compacted base
Unclear · Quantity: insufficient data“6-inch gravel base” — sample document, page 1
The quote does not say whether 6 inches is the compacted or loose thickness, or identify the aggregate specification.
Ask: Is the 6-inch thickness measured after compaction, and what aggregate specification will you use?
02 / Disposal
Not mentioned · Quantity: not checkedNo explicit spoil transport or disposal allowance appears in this short example. This does not establish that disposal is excluded from the total.
Ask: Does the total include loading, haulage and disposal, and are weight limits or extra loads chargeable?
03 / Concrete paver area
Included · Consistent under assumptions“280 sq ft concrete pavers” — sample document, page 1
20 × 14 = 280 sq ft net area. At an illustrative 10% waste, procurement area is 308 sq ft. Net installed area and ordered area are different quantities.
Ask: Is cutting waste included in your price, and which paver model and thickness are specified?
