Commercial Dock & Marine Construction FAQs

The right solution depends on the site, intended use, environmental exposure, code requirements and the engineer’s requirements. These answers provide a practical starting point for marine contractors, engineers, developers, marina owners and public agencies.

Project Planning & Quotations

What information is needed to request a quote?

Helpful information includes the project location, plans or sketches, dimensions, intended use, anticipated loads, water-level or tidal range, anchoring or foundation concept, decking choice, utility requirements, delivery constraints and desired schedule. If the design is still preliminary, send what you have and identify the decisions that remain open.

Can products be customized for a specific project?

Many dock, gangway, catwalk and pedestrian bridge systems can be configured for project-specific lengths, widths, loads, railings, decking, utilities and connection details. Final options depend on the product, site conditions, applicable codes and engineering requirements.

Do you provide installation?

Dock and Marina focus is on product supply, product selection and project support. Installation is generally coordinated through the project’s marine contractor or general contractor. Contact us early so engineering, delivery and installation requirements can be coordinated appropriately.

What areas do you serve?

We serve Florida, the Bahamas, the Caribbean and customers throughout the United States.

How early should products be selected?

Product selection should begin during planning or design whenever possible. Early coordination helps the project team account for structural requirements, anchoring, access, utilities, permitting, manufacturing lead times and delivery logistics before those items affect the schedule.

Floating & Fixed Docks

What is the main difference between a floating dock and a fixed dock?

A floating dock rises and falls with the water and is commonly used where tides or water levels change. A fixed dock is supported at a set elevation by piles or another foundation system. The better option depends on water-level variation, depth, exposure, intended use, accessibility, budget and site-specific engineering.

Are aluminum floating docks suitable for saltwater?

Properly designed aluminum floating dock systems are widely used in coastal and saltwater environments. Material selection, alloy, fasteners, dissimilar-metal isolation, electrical systems, flotation, connections and maintenance all affect long-term performance and should be coordinated for the specific site.

How long does an aluminum floating dock last?

Service life varies with design, materials, exposure, loading, installation and maintenance. A quality commercial system designed for the actual environment can provide long-term service, but no responsible estimate should be made without considering local conditions and the complete system.

How are commercial floating docks anchored?

Common approaches include guide piles, piling hoops, cable or chain systems, stiff arms and other engineered systems. Water depth, bottom conditions, tide or reservoir fluctuation, wind, wave action, currents, vessel loads and permitting requirements influence the anchoring method.

Can utilities be incorporated into a floating dock system?

Yes. Electrical service, water, lighting, fire protection and pump-out components can often be coordinated with a commercial dock system. Utility design must account for movement, flexible connections, code requirements, corrosion protection, access and maintenance.

What decking options are available for docks?

Options may include Ipe and other hardwoods, composite decking, concrete pavers, slip resistant aluminum decking and many other choices. Selection should consider slip resistance, heat, appearance, span ratings, fasteners, maintenance, fire requirements, accessibility and the intended level of use.

Gangways, Catwalks & Bridges

How is the correct gangway length determined?

Gangway length is influenced by the horizontal distance to the dock, tidal or water-level range, required clear width, allowable slope, landing arrangement and accessibility requirements. The steepest operating condition should be evaluated rather than relying only on the normal water level.

Can an aluminum gangway be ADA compliant?

An accessible route may be possible, but compliance depends on the complete route—not only the gangway. Length, slope, landings, handrails, transitions, water-level fluctuation and any applicable exceptions must be reviewed by the project’s design professional and permitting authority.

What information is needed to specify a pedestrian or utility bridge?

Typical inputs include clear span, width, design loads, intended traffic, utilities to be carried, railing requirements, deck type, site exposure, support conditions, applicable codes, finish and shipping or erection constraints. An engineer should establish the governing criteria.

Why is aluminum often considered for gangways, catwalks and pedestrian bridges?

Aluminum offers a favorable strength-to-weight ratio and corrosion resistance, which can simplify handling and reduce maintenance in many marine and outdoor applications. Suitability still depends on span, loading, fatigue, connections, environment, budget and engineering requirements.

Seawalls, Decking & Greenheart Marine Piling

When is vinyl sheet piling used?

Vinyl sheet piling is commonly considered for seawalls, bulkheads, shoreline stabilization, erosion-control structures and water-control applications. It is valued for corrosion resistance, but section selection, embedment, tie-back design, soils, water pressure, surcharge loads and installation method must be engineered for the site.

How does vinyl sheet piling compare with steel, concrete or wood?

Vinyl does not rust or rot and can be an effective option in many marine environments. Steel may provide greater stiffness or capacity for demanding conditions; concrete offers mass and durability; and treated wood may suit certain traditional applications. Engineering requirements, site conditions, installation equipment, expected service, maintenance and life-cycle cost should drive the comparison.

Why is Ipe used for marine decking?

Ipe is a dense tropical hardwood valued for strength, wear resistance and durability in demanding exterior applications. Proper drying, ventilation, end sealing, fastening, spacing and maintenance are important. Appearance will weather over time unless an appropriate finish and maintenance program are used.

Why is Greenheart used for marine piling?

Greenheart is a dense, durable tropical hardwood with a long history in heavy marine construction. It is considered for piles, fenders and structural marine components where strength, abrasion resistance and exposure performance are important. Grade, dimensions, treatment requirements, engineering and responsible sourcing should be confirmed for each project.
