How to compare construction quotations line by line
On your checklist as: “Quote comparison and conflicts pass done”
Every quote checked line by line against your baseline and against each other - including the footnotes, where exclusions hide. The known omissions get named: termite treatment, waterproofing warranty, debris removal and more.
What to look at
- Every known-omission item either priced or explicitly excluded
- Every footer and margin note read and classified
How to check it yourself
Compare line by line, never total against total. Sweep for the known omissions: anti-termite treatment; waterproofing warranty; slab thickness in millimetres; TMT grade, Fe500 against Fe500D; electrical point counts; external works and compound wall; water and electricity during construction and whose cost that is; and debris removal. Read footer and margin notes and exclusion clauses, where Kerala quotes bury their exclusions. Run a pairwise specification diff across companion documents for mix, slab and wall thickness, steel grade, aggregate size and scope.
Where this comes from: IS 6313 (Part 2) — anti-termite pre-constructional chemical treatment (indian standard or building code)
