Comparing Apples with Apples: How to Choose the Right Engineering Quote
When you’re planning a residential build or renovation, getting multiple quotes is a smart move, but it’s not always easy to compare them directly. Engineering quotes can vary significantly in price, detail and scope. So how do you know you’re comparing apples with apples?
Here’s what to look for when assessing engineering quotes, and how to make an informed decision that protects your project from cost blowouts, delays or hidden gaps.
1. Scope of Services
Not all quotes cover the same ground. One consultant might include structural design only, while another includes geotechnical reporting, civil works and construction monitoring. Check what each quote actually covers and what’s excluded. A lower quote may look attractive up front, but if it leaves out essential services, it can end up costing more in the long run.
Tip: Ask for a breakdown of what’s included, such as site visits, reports, consent documentation, construction monitoring, meetings and revisions.
2. Level of Detail
A vague quote often means vague deliverables. Good engineers will clearly outline what they’re providing, how long it will take and what’s needed from your end. Detailed scoping signals a consultant who’s thinking ahead and familiar with council requirements, not just pricing a job but planning to deliver it properly.
Tip: Choose the quote that shows they understand your site, not just your budget.
3. Experience with Similar Projects
Residential projects come with their own set of challenges, especially on tricky or sloping sites. Make sure you’re working with an engineering team that knows what to expect. Quotes may vary based on a firm’s experience, resourcing and how confident they are in dealing with council processes or specific ground conditions.
Tip: Ask if they’ve worked on projects like yours. If they have, they’ll likely anticipate issues and resolve them early.
4. Timeframes and Communication
The cheapest quote isn’t worth much if the delivery is delayed or unclear. A reliable engineer will give realistic timeframes, communicate throughout and make the process easier, not more stressful.
Tip: Ask how they manage timelines, client updates and coordination with other consultants such as architects or builders.
5. Hidden Costs
Some quotes don’t include key items like site visits, council meetings or PS4 construction monitoring. These are often essential for consent and sign-off. Make sure you know what’s an extra and how much those extras might cost.
Tip: Look for transparency. If a quote seems too low, it may be incomplete.
