Drain, Waste & Vent (DWV) Pipe Replacement

Native Technologies provides full-service construction project management for condominium associations and commercial properties across Hawaii. We specialize in DWV pipe replacements in occupied buildings, planning, sequencing, and delivering complex stack work while keeping residents informed and buildings operational.

Why DWV replacements matter in Hawaii

Aging cast-iron and galvanized stacks corrode in our salt-air environment, leading to leaks, backups, odors, and hidden moisture damage. Unplanned failures drive emergency repairs, unit downtime, and rising insurance exposure. Proactive, well-scoped DWV projects reduce risk, protect common and unit interiors, and stabilize association budgets.

Our approach

We manage the entire effort, from early diagnostics through warranty, so boards, managers, and residents have a single accountable partner.

  1. Assessment and scope definition
    Leak history review, scoping or laboratory assessment as appropriate, unit surveys, and prioritization of specific system areas.
  2. Budgeting and financing coordination
    Opinion of probable cost, cash-flow modeling, and lender coordination. We support the consent to borrow process and keep your board’s fiduciary responsibilities front and center.
  3. Independent owner’s agent
    We remain independent from designers and contractors. This preserves competitive bidding, removes conflicts of interest, and keeps recommendations squarely aligned with the association’s best interests.
  4. Team assembly and design management
    We assist in selection of the design team, then coordinate deliverables, specifications, and permit strategy (design-bid-build or design/build).
  5. Bidding and contracting
    Structured RFPs, pre-bid walkthroughs, proposal leveling, and contract negotiations so the board can award with confidence.
  6. Resident logistics and phased execution
    Stack-by-stack sequencing, water shutdown schedules, notice cadence, access coordination, protection of finishes, and contingency planning for renovated units.
  7. Construction management with regular site visits
    OAC meetings, submittal/RFI/change-order control, schedule tracking, photo-rich reporting, field observations, and quality checks (firestopping, acoustic wrap, testing). Onsite coverage scales with project intensity, including daily in-unit checks when work is active.
  8. Turnover, restoration, and warranty
    Punch lists, closeout, as-builts, operations guidance, and warranty tracking.

Owner and resident education

Clear communication is a core deliverable. We start with a project overview and town hall, then issue plain-language bulletins through construction. The goal is simple: residents know what to expect, when access is needed, and how long utilities will be affected.

Permitting Strategy

We align the design and permit path with Honolulu DPP realities, and when appropriate, we evaluate lawful pre-permit options to responsibly reduce schedule risk.
