Fillable construction templates
with your business name on them
Variation order, site instruction, extension of time claim, practical completion checklist and defects list. Type your details once, download the ones you need, and every box on them is a real form field.
What each form is for
- Variation order
- The change, its price with GST shown separately, the days it adds, and both signatures before the work starts. The most argued-over piece of paper on a renovation, so it is the one to get in writing.
- Site instruction
- What was asked for on site, by whom, when, and whether it changes price or time. An instruction records; a variation changes the contract.
- Extension of time claim
- The cause, the days claimed, the evidence attached, and a response block for the client. Most contracts set a deadline for giving notice of a delay, so the dates matter.
- Practical completion checklist
- The handover walk-through: what was inspected, what is outstanding, when it will be done, and when the defects period ends.
- Defects list
- Ten lines for location, defect and date rectified, and a sign-off when the list is closed.

Send any of these with PDF Forms
Upload the template into OneBookPlus, fill in your side on the document, and send the client a private link from the job or the quote it belongs to. They fill in what is left, draw a signature, and the completed copy is filed against the client with a completion record on the last page. Included for trades and construction businesses on every plan.
Frequently asked questions
- Are these legal contract documents?
- No. They are working forms for the paperwork that happens during a job: a variation, an instruction, a delay claim, a handover, a defects list. The building contract itself, and the notice periods and definitions these forms refer to, come from your own contract, such as an HIA or Master Builders contract. Read the small print on each form and check your contract before relying on one.
- What does fillable mean here?
- Every box on the PDF is a real form field. Open the file in Acrobat Reader, Preview, a phone or a browser, click a box and type. Tick boxes tick. The signature lines are fields too, so the file works with any fill-and-sign tool, including our free one.
- Is my business information stored?
- No. The PDF is built on your device from what you type, and downloaded from your browser's memory. Nothing you type here is sent to us: the page records the same anonymous usage analytics as the rest of the site, and none of your business details are in it. Reload the page and the fields are empty again.
- Can I change the wording or add fields?
- The downloaded PDF can be edited in Adobe Acrobat (Prepare Form) or PDF Expert like any fillable PDF: add, move or rename fields, or change the text. If a form is missing something you use on every job, tell us and we will add it.
- How do I get a client to fill in and sign one of these?
- Email the PDF and ask them to fill and sign it in their PDF viewer, or upload it into PDF Forms in OneBookPlus, fill in your side, and send them a private link. They fill in what is left, sign by drawing, and you both get the completed copy with a completion record on the last page.
Sources & methodology
How we calculate this
Each template is a fixed list of labelled fields laid out on A4 by pdf-lib in your browser: text boxes, multi-line boxes, tick boxes and signature lines are created as real PDF form fields, and your business name, ABN, licence, phone and email are printed in the header from what you type. The wording is generic working paperwork written for Australian residential and light commercial building; it does not reproduce any industry association's contract and it is not legal advice. Nothing you enter leaves your device.
