NEW CONSTRUCTION PLUMBING
NexGen supports residential and commercial construction with plan review, underground plumbing, water and drain systems, rough-ins, top-outs, gas piping, fixture coordination, equipment connections, testing, and documented project scopes.
PROJECT TYPE
Both project types move through similar plumbing phases, but the plans, fixture schedules, equipment, approvals, documentation, testing, site access, and project teams may be very different.
Plumbing packages for custom homes and residential construction, including underground piping, water distribution, drainage and venting, gas piping, water-heater planning, fixture coordination, rough-in, top-out, trim, and final testing.
EXPLORE RESIDENTIAL NEW CONSTRUCTIONPlan-based plumbing scopes for commercial projects, including underground systems, rough-in and top-out phases, equipment and fixture coordination, documentation, general-contractor communication, testing, and approved closeout work.
EXPLORE COMMERCIAL NEW CONSTRUCTIONThe correct project path helps NexGen request the right plans, schedules, contacts, and approval information before pricing or scheduling begins.
MORE THAN A ROUGH-IN
Rough-in is one visible construction milestone, but it depends on earlier planning and must be followed by testing, fixture and equipment connections, final adjustments, and closeout.
Review available drawings, specifications, fixture schedules, equipment requirements, alternates, exclusions, access conditions, project phases, and approval procedures.
Install approved below-slab, below-grade, building-drain, water-service, sleeve, penetration, and other underground plumbing work before the relevant areas are covered.
Install approved water, drain, waste, vent, gas, valve, equipment, and fixture connection locations while framing and required access remain available.
Return after the required walls, floors, cabinets, surfaces, utilities, fixtures, and equipment are ready for approved plumbing connections.
Test accessible completed plumbing work as project conditions allow, address approved punch-list items, document limitations, and identify remaining responsibilities.
Each phase should have a defined starting condition, completion point, approval path, and responsibility for the work that follows.
ROUGH-IN AS A PROJECT PHASE
NexGen may review phase-specific work separately when the existing work, plans, testing status, responsibility boundaries, and remaining plumbing package can be clearly documented.
PRICING THE ACTUAL PROJECT
Counts are useful, but location, type, specification, piping distance, equipment, access, schedule, testing, and project responsibilities determine the actual plumbing scope.
Missing or conflicting information should be identified before the scope is treated as final.
BEFORE THE SLAB OR FLOOR CLOSES
Work that will be concealed should be reviewed, tested, documented, and approved as required before another party covers it.
CONNECTED BUILDING SYSTEMS
Pipe sizing, pressure, fixture demand, shutoffs, equipment, building layout, material requirements, and future access affect how water is distributed through the project.
Fixture units, pipe size, slope, venting, cleanouts, elevations, branch routes, stacks, roof penetrations, and connection points affect the drainage system.
Final appliance input, available capacity, pipe size, route, regulators, pressure requirements, shutoffs, testing, and the approved scope affect gas piping work.
Fixture demand, storage, recovery, flow, temperature rise, equipment type, utilities, venting, drainage, recirculation, location, and access affect hot-water planning.
One incomplete schedule or late equipment change can affect several parts of the plumbing package.
KEEPING THE PROJECT BUILDABLE
NexGen should be notified before another trade covers, blocks, damages, relocates, or changes approved plumbing work.
WHEN THE PROJECT CHANGES
A field condition is not automatic authorization to expand the plumbing scope.
FROM PLANS TO CLOSEOUT
Tell us whether the project is residential or commercial, whether plans are complete, whether bidding has started, and which construction dates are already scheduled.
Share the available drawings, specifications, fixture schedules, equipment schedules, addenda, alternates, scope requirements, and contact list.
NexGen identifies included plumbing work, excluded work, owner-furnished items, responsibility divisions, testing requirements, and information that remains unclear.
The proposed scope is organized around the available documents, project phases, known quantities, access, schedule, and stated responsibilities.
Conflicts, missing specifications, substitutions, access concerns, and responsibility questions should be addressed through the approved project communication process.
Approved underground plumbing is installed, tested, documented, and prepared for cover as project conditions and assigned responsibilities allow.
Approved water, drain, vent, gas, valve, fixture, and equipment connection locations are installed while framing and required access remain available.
Approved fixtures and equipment are connected after the required finishes, utilities, products, access, and supporting work are ready.
NexGen tests accessible completed work as conditions allow, addresses approved punch-list items, and explains remaining limitations or responsibilities.
QUESTIONS
Yes. Residential and commercial projects follow different planning, documentation, fixture, equipment, coordination, and approval paths, so each project should begin with the correct service page and current project documents.
Rough-in is one phase of a larger plumbing package. It depends on plans, underground work, fixture specifications, framing, testing, inspections when applicable, and responsibility for final fixture and equipment connections.
A phase-specific request may be reviewed when the existing underground work, plans, testing status, fixture information, responsibility boundaries, remaining work, and approval process can be clearly documented.
The approved scope may include plan review, underground plumbing, water piping, drainage, venting, gas piping, rough-in, top-out, fixture connections, equipment connections, testing, documentation, and project coordination.
Provide the current plumbing drawings, architectural plans, specifications, fixture and equipment schedules, addenda, alternates, scope requirements, requested dates, and responsibility information.
Fixture counts may support early budgeting, but final pricing also depends on locations, specifications, pipe routes, equipment, access, utilities, project phases, testing, schedule, and responsibility boundaries.
Fixture and equipment purchasing responsibilities should be stated in the project documents or approved proposal. NexGen should not assume that all fixtures or equipment are contractor-furnished.
Excavation, backfill, compaction, concrete cutting, concrete repair, and slab work are included only when specifically listed in the written approved scope.
Permit and inspection responsibilities should be identified before work begins. NexGen does not assume responsibility for every permit, fee, inspection, or third-party test unless specifically included.
Revised plans, substitutions, added fixtures, deleted fixtures, equipment changes, and field directives should be documented and reviewed for scope, pricing, responsibility, and schedule impact before the work changes.
NexGen should be notified immediately. Reopening, exposing, retesting, repairing, or documenting prematurely covered work may require additional scope, scheduling, and approval.
Only the fixtures, equipment, and plumbing connections specifically included in the written approved scope are included. Equipment movement, electrical work, HVAC work, manufacturer commissioning, and specialty installation may remain with others.
Yes. The plumbing scope may be divided into underground, building areas, floors, rough-in phases, equipment phases, final connections, and punch-list work when the plans, access, schedule, and responsibilities support phased construction.
The project should identify an authorized decision-maker and change process. NexGen should document the condition, proposed work, cost, and schedule impact before proceeding beyond the existing authorization.
Yes. Call with the available project information when you need plan review or an estimate. Mention any scheduled construction phase, active leak, damaged piping, gas concern, or immediate site condition that requires prompt coordination.
Share the project type, drawings, fixture and equipment schedules, scope requirements, contacts, and construction dates so NexGen can begin reviewing the new-construction plumbing package.
