Avoiding Rework in Waterproofing Projects: The Power of Pre-Tender Reviews
Rework eats profits and damages client trust. Learn how a structured pre-tender review can save time, prevent costly mistakes, and boost your reputation in NZ’s competitive waterproofing market.
10/10/2025
In waterproofing, small details can create big problems. Missed falls, unconfirmed substrates, or unclear membrane transitions can turn a straightforward project into a costly rework situation.
Rework doesn’t just cost materials - it drains time, labour, and client confidence.
A Pre-Tender Review, led by a QS or estimator experienced in waterproofing, helps catch those issues before they become headaches.
Here’s what that looks like:
Plan Check for Missing Details
Before you quote, review drawings for unclear transitions, unlabelled areas, or missing upturn heights. A 10-minute review can prevent a $10,000 rework.Clarify Scope & Responsibilities
Who handles flashings, sealants, or joint finishes? A pre-tender checklist ensures you quote what you’ll actually install — not someone else’s scope.Supplier Spec Alignment
Your supplier’s technical rep can confirm if the chosen system is suitable for substrate, UV exposure, or expected movement. This ensures your quote matches warranty requirements.Document Everything
When you submit a tender, include your scope notes and assumptions. It’s professional, transparent, and gives you leverage if a dispute arises later.
