Retaining Wall Scope Audit for Manchester, NH
Retaining wall estimates depend on height, drainage, soil, access, engineering and finish material. A low wall-face price is not comparable to a complete structural wall with excavation, base, geogrid and drainage. Use the $10,408 midpoint as a planning number, then require the written scope below before comparing Manchester contractor bids.
Scope checks
- - Wall type: segmental block, poured concrete, timber, boulder, gabion or natural stone, with height, length, tiers and surcharge loads stated.
- - Groundwork: excavation, base depth, compaction, geogrid, drainage stone, perforated pipe, outlet location and soil haul-off.
- - Structural checks: engineering trigger height, fence/guardrail needs, slope stability, driveway or building surcharge and property-line constraints.
- - Closeout: permit responsibility, inspection timing, drainage discharge, backfill, finish grading, restoration and warranty.
Ask before deposit
- - What height or surcharge condition triggers engineering or a permit?
- - Does the price include drainage stone, pipe, geogrid, compaction and soil disposal?
- - Where will water discharge after the wall is finished?
Common misses
- - Comparing visible wall block only against a fully drained structural wall.
- - No drainage outlet or geogrid specification.
- - No plan for poor soil, access limits, fence loads or inspection requirements.
