How to Compare Seawall Estimates

Do not start with the total. First determine whether the estimates are pricing the same outcome.

Scope comparison table

CategoryWhat should be clear
Problem statementObserved condition and assumed cause
DesignWall type, elevations, embedment, anchors, cap, drainage and filters
Professional responsibilityWho supplies survey, engineering, sealed plans and inspections
PermitsWhich agencies, who applies, fees and excluded approvals
Existing structuresDocks, lifts, pools, pavers, fences, utilities and neighboring walls
ConstructionAccess, equipment, water work, demolition, dewatering and controls
CloseoutDisposal, restoration, final inspections, documents and warranty

Red flags worth slowing down for

  • A major structural conclusion without a site basis
  • “Permit included” without naming the responsible jurisdictions
  • Material named but no section, profile, reinforcement or system detail
  • Large deposit or urgency pressure before scope is defined
  • No explanation of soil loss, drainage or transitions
  • Verbal promises that conflict with exclusions in writing

Ask each bidder the same questions

What failure are you correcting? What will remain? Who designed the work? Which conditions could change the price? How will water and soil be controlled? What is specifically excluded? What documents will I receive at completion?
