Common Mistakes to Avoid When Using a Construction Estimating Service
Using a construction estimating service is one of the smartest steps you can take when planning a building project.
It helps you create a solid budget, manage costs effectively, and avoid unpleasant financial surprises.
However, to get the full benefit, it’s important to avoid some common mistakes.
In today’s article, we’ll highlight the key pitfalls people often fall into – and show you how to use a building estimating service properly to maximise your project’s success.
1. Providing Incomplete or Outdated Information
Your construction estimate is only as accurate as the information you provide.
Common issues include:
Using old or preliminary drawings
Missing specifications for materials or finishes
Incomplete site information
If your estimator doesn’t have the full picture, your cost plan might not reflect reality.
Always provide up-to-date, complete project documentation to get the best results.
2. Choosing the Wrong Estimating Service
Not all construction estimating companies are the same.
Mistakes include:
Hiring companies without UK-specific experience
Choosing based solely on price (cheapest isn’t always best)
Working with services that offer little or no support after delivering the estimate
Look for experienced, UK-based estimators like Reltic Construction Consultants, who understand local markets and offer ongoing advice.
3. Ignoring Recommendations and Advice
Good estimators don’t just produce numbers – they also give strategic advice.
Mistakes happen when clients:
Ignore suggested cost-saving alternatives
Stick rigidly to unrealistic designs or materials
Refuse to adjust budgets even when risks are identified
Take advantage of your estimator’s expertise to make smarter project decisions.
4. Failing to Update Estimates During Project Changes
Design changes are common – but failing to update your estimate can cause serious budget problems.
Always update your cost plan when:
Scope or specifications change
New regulatory requirements arise
Site conditions are different than expected
A responsive building cost estimator will help you manage these updates easily.
5. Treating the Estimate as a Fixed Price Contract
An estimate is a forecast, not a contractor’s final price.
It provides a strong foundation for budgeting and tendering, but final contractor quotes may vary.
Use your estimate as:
A realistic guide for evaluating tenders
A baseline for negotiation
A tool for project cost control
