Marine Construction Estimating Services
Tribuild supports marine contractors with quantity takeoffs for waterfront structures: piles, marine concrete and steel, and fender and mooring systems, quantified from the plans so pier, dock, and bulkhead bids are built on real numbers.
Marine bids hinge on piles, marine concrete and steel, and dredge volumes. Tribuild takes off waterfront structures from the plans and survey, piles by type, count, and length; marine concrete and steel by structure; and dredging by area and depth from the bathymetric survey.
Fender and mooring systems, shore protection, and underwater utilities are carried per the documents, and every deliverable ships with documented assumptions (including the tidal and subsurface risk that stays with the contractor) your team can price and defend.
What we estimate for marine construction
Piers
Pier deck, framing, and substructure quantities by area and structure.
Docks
Fixed and floating dock quantities by area and unit.
Wharves
Wharf deck and support quantities by structure.
Bulkheads
Bulkhead sheet pile, tiebacks, and cap by linear foot.
Seawalls
Seawall concrete/armor quantities by linear foot and volume.
Marinas
Marina floats, gangways, and utilities counted by unit.
Pile systems
Timber, concrete, and steel piles by count and length with driving notes.
Marine concrete
Marine-grade concrete for decks, caps, and structures by volume.
Marine steel
Structural and sheet steel by weight for marine structures.
Timber structures
Timber piles, decking, and framing by count and board measure.
Fender systems
Fender piles, panels, and units counted by unit.
Mooring systems
Bollards, cleats, and mooring hardware counted by unit.
Dredging
Dredge volumes by area and depth from the survey.
Shore protection
Riprap and armor stone by volume and area.
Underwater utilities
Submarine utility runs by linear foot where applicable.

Frequently asked questions
Marine structural plans and sections, pile and framing schedules, bathymetric survey for dredging, and specifications. Survey data drives dredge volumes.
Yes, timber, concrete, and steel piles by count and length, with driving and splice notes carried per the documents.
Yes, dredge volumes are derived from the bathymetric survey by area and depth; disposal and environmental scope are noted as assumptions.
Means and methods, marine equipment, final pricing, and licensed engineering remain with the contractor and design team.
