Variation Order Request

Contractor-initiated variation request under Cl. 36. Covers scope description, rate basis (schedule of rates / market rate), and time impact. Triggers employer's 14-day response obligation.

When to use this letter

When site conditions, employer instructions, or design changes alter the scope of work originally tendered. Send before executing the changed work; retrospective variation requests routinely get rejected.

Why this is different from a generic template

Clause numbers, not vague rights
Cites NHAI GCC Cl. 36 directly. Generic templates skip the clause reference and lose the legal anchor.
Indian contract context
Written for NHAI, CPWD, and MoRTH practice. Not a FIDIC document with Indian terminology pasted over it.
Evidence-ready structure
Notice periods, delivery method, and acknowledgement trail built in. Stands up at DRB and arbitration.

Skip the blank page. CivilBolt drafts this with your contract clauses filled in.

Upload your contract and CivilBolt produces a variation order request with the right clause references, notice periods, and delivery obligations already populated. Edit the specifics, send it out.
