Field reportsReplacement assembly

Specify Excavation, Pipe, Interfaces and Restoration

A replacement proposal should describe the complete below-grade sequence and the site impacts required to execute it. Pipe alone is only one part of the scope.
OBSERVE

Plan locating, protection and excavation

List utility-locate requirements, access width, equipment, shoring or safety questions, vegetation, hardscape and building protection. Begin the water-source file with a date and its symptom, drainage segment and outlet; attach the available evidence before making the investigation, repair or excavation decision. The next checkpoint is “Map spoil and material movement.” Keep neighbouring-property constraints visible. Keep that action beside its observation. The drainage-scope reviewer can then distinguish the intake water-source file from drainage closeout record material added during later pricing or investigation.

  • Keep neighbouring-property constraints visible.
OBSERVE

Map spoil and material movement

Review excavation access, utility protection, wall interfaces, drain components, outlet assumptions, backfill and restoration in the context of the actual property rather than as a standard allowance. Drain replacement affects excavation, wall access, connections, backfill and surface restoration; pipe length alone cannot describe that scope. Identify dewatering questions; then keep neighbouring-property constraints visible. Label each drainage photograph, drawing and prior record by symptom, drainage segment and outlet and date. When an unviewed drain or below-grade condition remains, record it in the water-source file; identify the drainage-scope reviewer review or drainage closeout record document that could resolve it. Surface water at one location cannot establish the route or condition of the buried drainage system.

  • Identify dewatering questions
  • Keep neighbouring-property constraints visible
DEFINE

Define the wall and drainage assembly

State how exposed wall condition is documented, what interface or drainage components are proposed, and how pipe, aggregate, cleanouts and outlet are addressed. Describe each symptom, system segment and outlet separately, citing its supporting drainage photograph, measurement or dated document. Record connection assumptions separately. A finding at one symptom, drainage segment and outlet may alter the proposed investigation, repair or excavation decision; unobserved parts of the property drainage system stay outside the available evidence.

  • Record connection assumptions separately.
DEFINE

Request current material details

“Request current material details” belongs on its own line in the water-source file. For the symptom, drainage segment and outlet, pair the drainage photograph evidence with any concealed or untested property drainage system limits. Do not conceal wall findings before review. Record connection assumptions separately. Cross-reference the drainage investigation or construction response answer to its drainage photograph; include the water-source file drawing, a product document for the drainage investigation or construction response, or a dated reply from the drainage-scope reviewer. Place the investigation or authority checkpoint before excavation advances, below-grade work is covered or an outlet assumption becomes embedded in the price.

  • Do not conceal wall findings before review
  • Record connection assumptions separately
DEFINE

Specify tests, backfill and restoration

Describe inspection points, flow or other reviewed checks, compaction or backfill records, final grading and restoration limits. Before proceeding, collect as-built and closeout evidence. Give task ownership to the drainage-scope reviewer; place its checkpoint before the investigation, repair or excavation decision, then name the expected drainage closeout record. This separates current water-source file evidence from the proposed drainage investigation or construction response. Put manufacturer information and drainage-scope reviewer input in the drainage closeout record; file authority questions under the relevant property drainage system decision.

  • Collect as-built and closeout evidence.
HANDOFF

Use photos before concealment

Resolve “Use photos before concealment” before ranking proposals. State the baseline symptom, drainage segment and outlet, proposed drainage investigation or construction response, exclusions, quantities and written change process. List landscaping and hardscape restoration levels. Collect as-built and closeout evidence. Review each drainage photograph while it can still change the investigation, repair or excavation decision. Record a dated investigation, repair or excavation decision choice or assign the remaining unviewed drain or below-grade condition. Track that uncertainty in the drainage closeout record, outside the lump-sum total.

  • List landscaping and hardscape restoration levels
  • Collect as-built and closeout evidence
HANDOFF

Complete the replacement assembly record

Finish this replacement assembly as a water-source file: include its starting evidence, location map, proposed drainage investigation or construction response and unresolved limits. For “Specify Excavation, Pipe, Interfaces and Restoration,” justify each drainage investigation or construction response inclusion and assign the next unviewed drain or below-grade condition. In the water-source file, list the approvals, product records and drainage closeout record expected. Continue with “Verify Where Collected Water Can Go”, “Normalize Investigation, Excavation and Restoration”, and “Match the Scope to Documented Condition” for related property drainage system decisions. Use the water-source file guide links for any wider drainage investigation or construction response comparison. Attach each dated Port Coquitlam or provincial reference to the outlet, permit or system question it actually addresses.

  • Name the next investigation, repair or excavation decision, responsible drainage-scope reviewer and water-source file evidence still required
  • Retain dated official property drainage system sources and guide links within the drainage closeout record
