THE ESTIMATING ANSWER
For one washer standpipe point, start with a defined scope and measurement basis. Measure pipe run, standpipe height, trap location and fall to the existing waste. Show pipe, trap and fittings separately from wall opening and labour. Price the listed tasks separately and state the condition that would require a revision: Insufficient fall or an undersized receiving line requires redesign.
This guide uses a fictional project in Dartmouth, Nova Scotia: One washer standpipe point. Its matching estimate and PDF give each scope decision a visible CAD cost line. Use the document to understand the structure; verify the actual building, product schedule, labour and supplier inputs before preparing a client quote.
1. Define the measured job
Add one washer drain connection along a short accessible utility-room route to a confirmed suitable waste line. Measure pipe run, standpipe height, trap location and fall to the existing waste. 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.
Measurement basis: Measure pipe run, standpipe height, trap location and fall to the existing waste.
2. Build a product and labour schedule
Show pipe, trap and fittings separately from wall opening and labour. This example has 7 distinct lines, including route and waste survey, local wall access, pipe and trap allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Selections to confirm: Show pipe, trap and fittings separately from wall opening and labour.
3. Sequence the work and handoffs
Confirm the downstream drain and appliance position before cutting. 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.
Work sequence: Confirm the downstream drain and appliance position before cutting.
4. Set a change boundary
Insufficient fall or an undersized receiving line requires redesign. The example excludes washing machine purchase, new water supply or buried drainage. Record the discovery, agree the revised work and update the estimate before adding it to the job.
If the job changes: Insufficient fall or an undersized receiving line requires redesign.
Review the Canadian job address
Verify the existing water, waste and fixture connections on site. Confirm who handles any required trade work, approvals and inspections for this address; this fictional document does not decide them.
Count the actual units, site visits and selected products separately. A count in this example is a document input, not a substitute for inspecting the real property. The example amounts are fictional CAD document inputs, not current rates for Dartmouth, Nova Scotia or another community. A site visit and current supplier information are needed to replace them.
Work through the itemized calculation
Check each extension of quantity and rate in the paired PDF. Two lines from this project are:
- Route and waste survey: 1 job × C$215.00 = C$215.00.
- Local wall access: 1 job × C$225.00 = C$225.00.
Adding all 7 rounded line amounts gives C$2,270.00. The PDF shows 0% tax and the same total before any markup. The sample shows 0% tax only to make the arithmetic visible. Determine any applicable GST, HST or PST and markup for the actual work before sharing a quote.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Route and waste survey | 1 job | C$215.00 | C$215.00 |
| Local wall access | 1 job | C$225.00 | C$225.00 |
| Pipe and trap allowance | 1 job | C$325.00 | C$325.00 |
| Standpipe and support allowance | 1 job | C$175.00 | C$175.00 |
| Connection labour | 7 hours | C$120.00 | C$840.00 |
| Flow and leak check | 1 job | C$195.00 | C$195.00 |
| Wall closure and cleanup | 1 job | C$295.00 | C$295.00 |
| Illustrative subtotal | C$2,270.00 | ||
Scope and pricing boundaries
Add one washer drain connection along a short accessible utility-room route to a confirmed suitable waste line.
Outside this example: No washing machine purchase, new water supply or buried drainage.
Keep the product allowance, installation work and any unresolved condition visible as separate decisions. If access or the selected product changes, update the affected quantity or rate and explain the revision before the client relies on the estimate.
Before you send the estimate
- Measure pipe run, standpipe height, trap location and fall to the existing waste.
- Show pipe, trap and fittings separately from wall opening and labour.
- Confirm the downstream drain and appliance position before cutting.
- Insufficient fall or an undersized receiving line requires redesign.
Check the business, client, property, dates, line extensions and notes. The laundry drain connection installation PDF example shows one way to present them. Its short PDF note lists the brief's scope exclusions; the fuller project limits above should guide your own scope.
