Separate the original scope, approved net changes and unresolved requests. In this example, TRY 6,000,000 becomes TRY 6,210,000 after approvals. A TRY 6,300,000 control limit leaves TRY 90,000. Approving a further TRY 150,000 request would exceed that limit by TRY 60,000.
A fictional change register prepared for Lizaz, not a real quotation or market price. Amounts use the same assumed scope and tax basis. Currency effects, price adjustment and other costs are outside this limited calculation.
1. Preserve the original scope
Start the register with the agreed scope and drawing revision. Describe the changed product, quantity, unit, installation and work being removed. Adding the full new product price while forgetting the agreed credit for the old scope can double-count the same work.
The example starts at TRY 6,000,000 and uses an owner's control limit of TRY 6,300,000 for the same scope. The TRY 300,000 difference is a chosen budget allowance, not a contract sum or automatic permission to spend.
2. Separate commitments from requests
| Record | Status | Budget effect |
|---|---|---|
| Original scope | Baseline | 6,000,000 |
| C-01 Window specification | Approved net addition | +180,000 |
| C-02 Pergola omitted | Approved net credit | −60,000 |
| C-03 Additional electrical work | Approved net addition | +90,000 |
| Approved scope total | 6,000,000 + 180,000 − 60,000 + 90,000 | 6,210,000 |
| C-04 Landscaping request | Pending; excluded from total | +150,000 |
Net approved changes are TRY 210,000, giving an approved scope total of TRY 6,210,000. C-04 stays visible in its own pending row. It has not been added to the approved total, but its possible cost has not disappeared.
Headroom is TRY 6,300,000 − TRY 6,210,000 = TRY 90,000. If C-04 is approved at TRY 150,000, the conditional total becomes TRY 6,360,000, exceeding the limit by TRY 60,000. This is the budget effect of the listed changes, not a payment schedule, cash-flow forecast or final account.
3. Give each change seven fields
Five days quoted for one product change and three for electrical changes do not necessarily make eight days of project delay. Work may overlap or may not affect the critical sequence. Review the combined effect against the current programme rather than adding every duration mechanically.
- Unique number and date, with later revisions linked to the same record.
- Reason and scope: the need it meets and the original work it replaces.
- Drawing or product reference, measured quantity and revision.
- Net amount: additions, agreed omissions, consistent tax basis and quotation validity.
- Programme effect: procurement, dependencies and any delay shared with other changes.
- Decision: requester, technical reviewer, cost reviewer and authorised approver.
- Closeout: installed quantities, inspection result and final cost agreement.
4. Show the same three totals every time
Report the original scope, the approved current scope and a conditional total for priced open requests. Where a request has no price yet, show it as unpriced with an owner and due date, outside the numeric total. An incomplete forecast should remain visibly incomplete.
An owner's note might say: ‘C-04 requests TRY 150,000; headroom is TRY 90,000. Review a reduced scope, alternative specification or revised control limit. The approved budget remains unchanged until the authorised decision is recorded.’ Contractual emergency-work and notification provisions still apply.
Frequently asked
Quick answers
Do pending changes enter the approved budget?
No. Keep them in a separate request or risk row, and show a conditional scenario where a price is known.
Is omitted work always credited in full?
No. Review work already done, orders and cancellation or return conditions. The TRY 60,000 example assumes an agreed net credit.
Does an available allowance authorise extra work?
No. Scope, net cost, programme effect and approval under the contract still need to be recorded.
