Project scope: One paved patio edge

Install a surface drainage channel along an existing paved patio edge and connect to a confirmed suitable outlet.

The fictional project is set in St. John’s, Newfoundland and Labrador. Cedar & Beam Builders and Jordan Taylor are example names, not a contractor and client case study. The matching guide (https://quicklyestimates.com/en-ca/guides/how-to-estimate-patio-drainage-installation/) explains how measurement, product selection and site conditions affect the estimate.

The 7 CAD cost lines

The table uses the exact items, quantities and unit rates in the app-exported PDF. Multiply each quantity by its rate to check the amount. These chosen figures demonstrate the document; they are not surveyed prices or suggested rates for St. John’s, Newfoundland and Labrador.

Patio drainage channel installation example · CAD Work item | Quantity | Unit rate | Amount |

Levels and outlet survey | 1 job | C$255.00 | C$255.00 |

Paving cut and lift | 45 linear ft. | C$19.00 | C$855.00 |

Trench excavation | 45 linear ft. | C$14.00 | C$630.00 |

Channel and grate allowance | 45 linear ft. | C$51.00 | C$2,295.00 |

Drain connection parts | 1 job | C$380.00 | C$380.00 |

Channel setting labour | 45 linear ft. | C$24.00 | C$1,080.00 |

Paving reinstatement and clean | 1 job | C$525.00 | C$525.00 |

Illustrative subtotal | C$6,020.00 |

Check the arithmetic

- Paving cut and lift: 45 linear ft. × C$19.00 = C$855.00.
- Trench excavation: 45 linear ft. × C$14.00 = C$630.00.

The rounded line amounts add to C$6,020.00 . The PDF's tax field is 0%, so its illustrated total stays C$6,020.00 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.

Measurement to verify: Measure channel run, paving cut length, invert level and available outlet route. Product decision: Keep channel units, grates and pipe fittings distinct from excavation and reinstatement.

The paving cut and lift line uses 45 linear ft., approximately 13.72 m. Check the route, cuts and supplier unit before setting a real quantity.

Assumptions and exclusions

Confirm outlet permissions and levels before cutting paving.

Outside this example: No new soakaway, sewer repair or large-area repaving.

No workable outlet or insufficient fall requires redesign rather than an assumed connection. 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. Confirm a change and update the estimate before adding work that was not in the base scope.
