Normalize Investigation, Excavation and Restoration

Compare the investigation basis, lengths, depths, access, excavation assumptions and viewed or unviewed system segments. 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 “Mark provisional quantities.” Flag unsupported diagnoses. 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.

• Flag unsupported diagnoses.

Review investigation evidence, provisional quantities, excavation effects, material assumptions, testing and as-built records in the context of the actual property rather than as a standard allowance. Drainage bids often differ in provisional depth, disposal, wall treatment and restoration, which need visible comparison rows. Separate investigation, repair and replacement; then flag unsupported diagnoses. 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.

• Separate investigation, repair and replacement
• Flag unsupported diagnoses

List wall interfaces, pipe, aggregate, cleanouts, sump or outlet work, dewatering, protection, backfill and restoration. Describe each symptom, system segment and outlet separately, citing its supporting drainage photograph, measurement or dated document. Use a written process for concealed changes. 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.

• Use a written process for concealed changes.

“Record material and connection assumptions” 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. Price hardscape and landscape limits. Use a written process for concealed changes. 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.

• Price hardscape and landscape limits
• Use a written process for concealed changes

Compare inspection points, reports, photos, final grading, cleanup, authority records and payment milestones. Before proceeding, avoid fixed outcome 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 fixed outcome promises.

Resolve “Tie payments to observable evidence” before ranking proposals. State the baseline symptom, drainage segment and outlet, proposed drainage investigation or construction response, exclusions, quantities and written change process. Retain footage and as-built notes. Avoid fixed outcome 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.

• Retain footage and as-built notes
• Avoid fixed outcome promises

Finish this proposal normalizer as a water-source file: include its starting evidence, location map, proposed drainage investigation or construction response and unresolved limits. For “Normalize Investigation, Excavation 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 “Record Where and When Water Appears”, “Define What the Inspection Must Show”, “Match the Scope to Documented Condition”, “Specify Excavation, Pipe, Interfaces and Restoration”, and “Verify Where Collected Water Can Go” 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
