Intervention decision

Define What Must Be Investigated First

Compare repair and replacement paths only after documenting wall construction, movement, drainage, foundation, loads and access.

Decision file

Build a clearer project record

01

Start with existing records

Gather drawings, permits, engineering or geotechnical documents, material information, drainage records and past repair invoices. Mark missing or conflicting information.

02

Describe the existing system

Record visible material, approximate geometry, steps or returns, transitions and connections. Do not infer hidden reinforcement, base, embedment or drainage.

03

Define the extent of change

Compare dated observations across the full wall rather than focusing on one crack. Note changes in nearby grade, paving, fences and water routes.

04

Test the proposal against the problem

Ask each proposer what evidence supports a repair, which conditions it addresses, what remains, and what would cause the scope to change.

05

Expose replacement dependencies

Replacement may involve excavation, access, temporary support, utilities, property boundaries, water control and restoration. List responsibility and exclusions for each.

06

Keep conclusions with the reviewer

This guide cannot determine stability, suitability of a repair, professional involvement or approval needs. Those decisions depend on the actual wall, loads and proposed work.

07

Compare limits on one wall plan

Place repair, partial replacement and full replacement limits on the same marked plan. For each alternative, identify the wall stations, elevations, transitions and adjacent areas included. Similar proposal language can otherwise hide materially different quantities, design boundaries and restoration obligations.

  • Use matching segment names
  • Mark work above and below the wall
  • Keep alternates outside the base scope
08

Test concealed-condition rules

Ask what evidence will be collected when excavation exposes the base, retained soil, buried drainage or unrecorded construction. Define who reviews that evidence, which findings pause work and how a changed design, quantity or price receives written authorization before proceeding.

  • Name stop-work evidence
  • Assign review responsibility
  • Require priced written changes
09

Record the decision rationale

The project file should explain why the selected intervention addresses the documented condition and why other paths were not chosen. Attach accepted professional inputs, unresolved limitations, construction verification requirements and maintenance information so a future owner can understand what the work did and did not establish.

  • Reference accepted drawing revisions
  • List unresolved adjacent conditions
  • Retain field and closeout records
10

Write the intervention decision record

After investigation, prepare a short record that ties each considered intervention to the same wall plan, accepted design inputs and documented conditions. State the lengths, elevations and drainage interfaces addressed; temporary works, access and restoration assumed; evidence that would expand the scope; and limitations that remain beside or below the work. Attach the accepted professional documents and proposal clarifications. This record should explain why the selected path was chosen without claiming that repair or replacement guarantees future performance, resolves undocumented adjacent conditions or removes the need for construction verification.

  • Identify the selected drawing revision
  • List rejected alternatives and reasons
  • Name construction hold points
  • Keep unresolved conditions visible
  • File final field-review evidence
