Field reportsIntervention decision

Match the Scope to Documented Condition

The intervention should match the documented extent and location of a problem. A recurring symptom may justify more investigation, but it does not prove whole-system failure.
OBSERVE

Review the investigation basis

List viewed and unviewed segments, cleaning results, observed deformation or damage, grade questions, materials and outlet information. 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 “Keep certainty levels visible.” Record whether symptoms changed after maintenance. 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.

  • Record whether symptoms changed after maintenance.
OBSERVE

Keep certainty levels visible

The comparison should address documented defect locations, certainty levels, local repair limits, system-wide alternatives and review hold points; otherwise two prices may describe materially different work. A localized obstruction and repeated defects along several elevations lead to different options, even if the interior symptom looks similar. Ask how locations were established; then record whether symptoms changed after maintenance. 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.

  • Ask how locations were established
  • Record whether symptoms changed after maintenance
DEFINE

Compare localized and system-wide paths

For each option, state the target condition, access, likely disruption, unresolved sections and evidence expected afterward. Describe each symptom, system segment and outlet separately, citing its supporting drainage photograph, measurement or dated document. Route structural or engineered matters appropriately. 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.

  • Route structural or engineered matters appropriately.
DEFINE

Do not assume one defect represents the whole system

“Do not assume one defect represents the whole system” 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. Separate pipe work from wall-waterproofing questions. Route structural or engineered matters appropriately. 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.

  • Separate pipe work from wall-waterproofing questions
  • Route structural or engineered matters appropriately
DEFINE

Set review and change checkpoints

Define what discoveries would change the selected path and how added work is authorized. Before proceeding, avoid dry-basement promises. 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.

  • Avoid dry-basement promises.
HANDOFF

Use before-and-after records

Resolve “Use before-and-after records” before ranking proposals. State the baseline symptom, drainage segment and outlet, proposed drainage investigation or construction response, exclusions, quantities and written change process. Keep outlet and connection questions in scope. Avoid dry-basement promises. 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.

  • Keep outlet and connection questions in scope
  • Avoid dry-basement promises
HANDOFF

Complete the intervention decision record

Finish this intervention decision as a water-source file: include its starting evidence, location map, proposed drainage investigation or construction response and unresolved limits. For “Match the Scope to Documented Condition,” 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 “Define What the Inspection Must Show”, “Specify Excavation, Pipe, Interfaces and Restoration”, and “Normalize Investigation, Excavation and Restoration” 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
