Why Your Estimate Needs to Change as the Job Gets Real

My Project Estimating  ·  Construction Estimating

An early figure is not a final one

Every job starts with a rough figure, priced against limited information, just to get a sense of what something might cost. The mistake is treating that early number as fixed once drawings and specifications firm up. An estimate needs to move through stages, getting more detailed and more accurate as more information becomes available, right up to the point you are pricing against a full package ready to build.

The stages a price should go through

A conceptual figure at the outset, refined once initial drawings exist, tightened further as the specification develops, and then a definitive price once everything needed to build the job is available. After that, a control estimate carries the job through construction, tracking against the original price as work proceeds. Treat any of these stages as the final word and you are pricing blind.

What actually causes prices to fall apart

The same handful of mistakes turn up again and again. Rates carried over from an old job without checking against current material and labour costs. Risk not priced in properly, so unknowns come out of margin instead of contingency. Assumptions made during pricing that never get written down anywhere, so nobody can trace where a figure came from once questions start.

Why this matters to your margin

Getting the estimate right at each stage is what lets you bid competitively without giving work away, allocate labour and plant properly, and know where you actually stand on a job rather than finding out at final account. A price that has been through a proper process, stage by stage, protects margin in a way a single rough number never can.

Send your drawings whatever stage you are at and we will build or refine the price properly. See a sample estimate to see the detail behind the figure.
