THE ESTIMATING ANSWER
Estimate concrete floor polishing by measuring the defined one ground-floor studio, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Newcastle example uses 7 itemised lines totalling £8,714.28; its exact quantities and rates appear in the paired app PDF.
The worked job is one ground-floor studio in Newcastle. The written scope is: Grind and polish an existing sound concrete slab in a ground-floor studio, with defined finish level and edge access. Its matching itemised example shows how that description becomes quantities, allowances and a PDF. These figures are fictional inputs for learning the method, so check the real site, specification and supplier or subcontractor costs before quoting.
1. Define the measured job
Grind and polish an existing sound concrete slab in a ground-floor studio, with defined finish level and edge access. Measure slab area, record coatings, cracks, hardness and edge length; a floor area alone misses prep. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.
Measure for this job: Measure slab area, record coatings, cracks, hardness and edge length; a floor area alone misses prep. Record the measured basis next to the relevant cost lines, since a room count, fitted length and purchased product quantity may each use a different unit.
2. Build a product and labour schedule
Specify the target sheen and any densifier or protective treatment as selected products. This example has 7 distinct lines, including condition survey and sample, surface preparation, initial grinding. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Specify the target sheen and any densifier or protective treatment as selected products. Keep a named allowance when the selection is open, and replace it once the actual product and delivery terms are known.
3. Sequence the work and handoffs
Complete a sample patch before committing to the grinding sequence. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.
Plan the handoffs: Complete a sample patch before committing to the grinding sequence. State which stage needs access or inspection before the next can begin, especially if a concealed condition might stop the work.
4. Set a change boundary
Deep cracks, moisture or unknown coating may change tooling and finish expectations. The example excludes slab repair, hazardous-coating removal or new concrete placement. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Deep cracks, moisture or unknown coating may change tooling and finish expectations. If this happens, write down the revised quantity and responsibility before adding an item to the customer estimate.
Worked project calculation
The paired PDF has 7 cost lines. For example, Surface preparation is 63.2 sq m × £25.85 = £1,633.72; Initial grinding is 63.2 sq m × £43.05 = £2,720.76. Each amount is the stated quantity multiplied by its unit rate. Recheck whether a line describes installed work, a material purchase allowance or a distinct visit before changing its quantity.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Condition survey and sample | 1 lump sum | £208.00 | £208.00 |
| Surface preparation | 63.2 sq m | £25.85 | £1,633.72 |
| Initial grinding | 63.2 sq m | £43.05 | £2,720.76 |
| Fine polishing passes | 63.2 sq m | £51.65 | £3,264.28 |
| Densifier allowance | 1 lump sum | £312.00 | £312.00 |
| Edge detailing | 33.5 metres | £13.12 | £439.52 |
| Final clean and finish check | 1 lump sum | £136.00 | £136.00 |
| Illustrative total | £8,714.28 | ||
Adding the 7 exact line amounts gives £8,714.28. The PDF uses a 0% tax input and no markup solely to display this arithmetic. Decide the appropriate tax, overhead and profit treatment for an actual job; the fictional rates are not local averages or price recommendations.

Outside this example: No slab repair, hazardous-coating removal or new concrete placement.
The role in this brief is flooring contractor. Confirm who supplies the selected products, makes the site safe, removes waste and signs off the work. Where opening up reveals a different condition, document it and issue a revised scope and price rather than silently extending the base estimate. Also check access, drying or curing time, and the client handoff described in the work sequence.
