THE ESTIMATING ANSWER
Estimate timber porch step rebuild by measuring the defined three exterior entry steps, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Glasgow example uses 7 itemised lines totalling £2,580.00; its exact quantities and rates appear in the paired app PDF.
The worked job is three exterior entry steps in Glasgow. The written scope is: Remove and rebuild three timber entry steps on sound existing support conditions, with selected decking and anti-slip finish allowance. 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
Remove and rebuild three timber entry steps on sound existing support conditions, with selected decking and anti-slip finish allowance. Measure rise, run, width, landing connection and support condition. 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 rise, run, width, landing connection and support condition. 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
Separate framing, tread boards and finish products. This example has 7 distinct lines, including step survey and layout, old step removal, framing timber allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate framing, tread boards and finish 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
Check the site design and local requirements before fabrication and removal. 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: Check the site design and local requirements before fabrication and removal. 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
Rot at the landing or failed footing changes support work. The example excludes full porch replacement, new foundation or railing installation. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Rot at the landing or failed footing changes support work. 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, Old step removal is 3 steps × £100.00 = £300.00; Tread material allowance is 3 steps × £144.00 = £432.00. 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 |
|---|---|---|---|
| Step survey and layout | 1 lump sum | £176.00 | £176.00 |
| Old step removal | 3 steps | £100.00 | £300.00 |
| Framing timber allowance | 1 lump sum | £368.00 | £368.00 |
| Tread material allowance | 3 steps | £144.00 | £432.00 |
| Step fabrication labour | 3 steps | £328.00 | £984.00 |
| Fixing and finish allowance | 1 lump sum | £184.00 | £184.00 |
| Final level check and clean-up | 1 lump sum | £136.00 | £136.00 |
| Illustrative total | £2,580.00 | ||
Adding the 7 exact line amounts gives £2,580.00. 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.
Scope and price boundaries
Remove and rebuild three timber entry steps on sound existing support conditions, with selected decking and anti-slip finish allowance.
Outside this example: No full porch replacement, new foundation or railing installation.
The role in this brief is carpentry 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.
