Our Delivery Model
What Turnkey Means at U.S. Aqua
Most contractors specialize in one scope - dredging, or earthwork, or excavation - and hand off everything else to subcontractors. That fragmentation costs the client time, money, and accountability. When something goes wrong, no one owns the problem.
U.S. Aqua mobilizes its own fleet, operators, and field leadership across multiple disciplines on the same project. The result: one point of contact, one contract, one team responsible from mobilization through demobilization. Daily reports come from our superintendent. Quality, schedule, and safety are managed by us - not coordinated across three or four subcontractors.
Whether the scope is a single specialty service or a multi-discipline project requiring dredging, marsh work, levee construction, and pipeline support all on the same site, U.S. Aqua scales its delivery to match.
Capabilities
Disciplines We Self-Perform
All of these can be combined under a single turnkey contract
Hydraulic & Mechanical Dredging
Submersible dredge pumps for moving sediment as slurry through discharge pipelines to placement sites.
Marsh & Environmental Restoration
Wetland creation, ridge restoration, and beneficial use of dredged material for CPRA, USACE, and conservation agencies.
Levee & Earthwork Construction
Flood protection levees, containment dikes, and bulk earthmoving in soft soils and wetland terrain.
Amphibious Excavation
Marsh excavators with low-ground-pressure undercarriages for soft soil, wetland, and shallow water work.
Pipeline & Energy Infrastructure
ROW clearing, trench excavation, backfill, and transmission line support in marsh environments.
Placement Area Maintenance
Dike management, weir maintenance, and capacity restoration for USACE and port authority placement sites.
What Sets Us Apart
One Contract. One Superintendent. One Team.
Self-Performing Core Scopes
Dredging, earthwork, amphibious excavation, and placement are all delivered by U.S. Aqua crews and equipment - never subcontracted out. Fewer handoffs, faster decisions, better outcomes.
Field Superintendent on Every Job
Every project gets a dedicated superintendent managing daily operations, coordinating crews and equipment, communicating with the client, and producing daily reports.
Flexible Contract Vehicles
Fixed-price for well-defined scopes, time-and-materials for evolving work, or subcontract arrangements with prime contractors. We match the contract type to the project.
Frequently Asked Questions
Turnkey Delivery FAQ
-
Does U.S. Aqua manage the entire project?
Yes. U.S. Aqua delivers projects under a single prime contract with one accountable point of contact from mobilization through demobilization. A field superintendent is assigned to every job to manage daily operations, coordinate equipment and crews, communicate with the client, and produce daily reports. Because we self-perform our core scopes - dredging, earthwork, amphibious operations, and placement - there are no subcontractor handoffs slowing down the schedule or fragmenting accountability.
-
What contract types does U.S. Aqua work under?
U.S. Aqua works under fixed-price contracts, time-and-materials (T&M) contracts, and subcontract arrangements with prime contractors. We tailor the contract vehicle to the project's complexity, scope definition, and client preference.
For well-defined scopes with clear quantities, fixed-price provides budget certainty. For exploratory or evolving work, T&M offers flexibility. We also frequently subcontract specialty scopes - dredging, amphibious excavation, marsh restoration - to general contractors managing larger civil projects.
-
Can U.S. Aqua handle both dredging and earthwork on the same project?
Yes. This is the core of our turnkey delivery model. Most contractors specialize in one discipline and have to coordinate with subcontractors for adjacent scopes - which adds cost, schedule risk, and communication complexity. U.S. Aqua self-performs dredging, mechanical excavation, levee and earthwork construction, amphibious operations, and dredged material placement using our owned fleet and crews. Combining these scopes under one contract eliminates handoffs and gives the client a single team responsible for the full delivery.
-
What geographies does U.S. Aqua cover?
U.S. Aqua is headquartered in New Iberia, Louisiana with a second office in York, Pennsylvania. Our primary service areas are the Gulf Coast and Mid-Atlantic, with active projects across Texas, Louisiana, Alabama, South Carolina, Delaware, and California. We mobilize equipment by barge, truck, or self-transport depending on the destination, and we've delivered projects in coastal marshes, inland waterways, port facilities, and remote wetland environments throughout these regions.
-
Where does U.S. Aqua perform energy infrastructure work?
U.S. Aqua performs pipeline and energy infrastructure work primarily across the Gulf Coast, with a concentration in coastal Louisiana where oil and gas pipelines, transmission lines, and utility infrastructure cross extensive marsh and wetland environments. Projects also extend to Texas, Alabama, and other Gulf Coast states.
