What are the hold points in a pool build, and what has to be proved at each one?
Verified against the primary source on .
Eleven. A hold point, or gate, is an evidence-backed decision made before the next irreversible commitment: project basis, site and concept, coordinated design, preconstruction, excavation and subgrade, rough-in, shell acceptance, backfill and utilities, deck and finish readiness, startup, and closeout. Gate 5, rough-in, is the one that matters most, because everything after it is buried.
Scope. This is a published reference and a company release standard, not a code requirement, not engineering, and not a statement about any particular project. It does not certify compliance or fitness for a specific pool. Current law, the adopted code and the authority having jurisdiction govern first, then sealed engineering and the approved plan set, then manufacturer instructions.
Most pool schedules are written as a list of activities. Dig, steel, plumb, gunite, tile, deck, plaster, fill. That is a sequence of work, not a sequence of decisions, and it hides the thing that actually determines cost and risk: at several points the next crew makes the previous crew’s work permanently expensive to inspect or correct.
A gate is the decision that happens before one of those points. Not a milestone, not a billing trigger. A decision that is either backed by evidence or is not.
THE ELEVEN GATES, with the release condition and the minimum evidence for each.
Gate 0, project basis. Scope, classification, site, authority, responsibilities, constraints and open assumptions are controlled. Evidence: approved project basis and authority matrix.
Gate 1, site and concept. Location, use, preliminary geometry, access, utilities, drainage, soil risk and feasibility are defensible. Evidence: concept and feasibility record.
Gate 2, coordinated design. Plans, sections, structure, hydraulics, plumbing, electrical, features, deck, finish and equipment agree with one another. Evidence: issued coordinated set and discipline approvals.
Gate 3, preconstruction. Permits, procurement, submittals, schedule, logistics, safety, quality, communication and hold points are ready. Evidence: preconstruction release package.
Gate 4, excavation and subgrade. Actual geometry, soil, groundwater, utilities, support, dewatering and professional observations are accepted. Evidence: as-excavated survey and subgrade release.
Gate 5, rough-in. Plumbing, embeds, reinforcing, bonding, pressure tests, inspections and deviations are complete before the shell. Evidence: the complete rough-in package.
Gate 6, shell acceptance. Placement, geometry, material, cure, tests, defects and repairs are accepted before loading or finish. Evidence: shell quality and repair record.
Gate 7, backfill, pad and utilities. Buried work, backfill, compaction, pad, equipment, utilities, labels and service access are accepted. Evidence: burial and equipment release.
Gate 8, deck and finish readiness. Support, drainage, joints, bonding, barriers, substrate, finish layers and fill plan are ready. Evidence: deck, finish and fill release.
Gate 9, startup and commissioning. Water, finish, hydraulics, equipment, controls, safety, chemistry and every operating mode meet acceptance. Evidence: commissioning dataset and baseline.
Gate 10, closeout. Permits, punch list, as-builts, warranties, manuals, training, safety and responsibility transfer are complete. Evidence: owner teach-back and final handoff.
WHAT A GATE DOES NOT DO. Passing a gate never overrides a higher project authority and never cures an open conflict. A permit inspection passing is not the same as the gate passing, and the gate passing is not the same as the permit inspection. They answer different questions.
WHY THIS IS PUBLISHED. A homeowner cannot evaluate a schedule of activities. A homeowner can ask which decisions are being made before their pool is covered, and who signed for them.
