Pool excavation and layout checklist

The pool, deck, equipment, barriers, drainage, and related structures should match the approved site plan and applicable zoning, easement, and setback requirements.

Compare layout stakes with the survey and permit drawings. Confirm distances are measured from the correct property and structure references and that future deck and equipment footprints are included.

- Layout measured from a fence that is not the property line

- Equipment or deck extends into an easement

- Barrier location not coordinated with pool position

- Field relocation not approved before excavation

Known utilities should be located and protected, and excavation access should not create unapproved risk to structures, slopes, septic systems, drainage, or neighboring property.

Review utility markings, private utility locating, overhead lines, access route, spoil storage, crane or concrete access, tree protection, and restoration plan.

- Private electric, gas, irrigation, or septic line not located

- Equipment passes too close to foundation or retaining wall

- Spoil blocks drainage or damages neighboring property

- Access plan conflicts with overhead conductors

Shell elevation, deck elevation, overflow, drainage routes, finished grade, building thresholds, and equipment elevation should follow the approved grading and drainage plan.

Verify benchmarks and planned finished elevations before excavation proceeds too far. Review how stormwater will move around the pool, house, deck, equipment, and retaining features.

- Pool or deck elevation threatens door thresholds

- Drainage directed toward house or neighboring lot

- Benchmark lost or changed during excavation

- Equipment pad elevation not coordinated with hydraulics or flooding

Unsuitable soil, fill, expansive material, groundwater, rock, buried debris, or instability should be evaluated under the approved design and by qualified professionals where required.

Document excavation faces and bottom, groundwater inflow, soft zones, old foundations, utilities, fill, and weather effects. Obtain written direction before over-excavation, dewatering, or structural changes.

- Soft or disturbed subgrade accepted without evaluation

- Groundwater pumped without a shell or dewatering plan

- Excavation geometry changed to avoid rock without redesign

- Buried debris left below shell or deck

Excavation should provide the space, shape, depth transitions, benches, steps, wall support, and working room required by the structural and pool-system plans.

Compare key dimensions, depths, slopes, steps, benches, beam area, wall lines, and equipment penetrations with the approved plan before steel placement.

- Over-excavation filled with loose spoil

- Steps or benches shifted from approved plan

- Insufficient space for shell thickness or plumbing

- Excavation sloughing changes structural geometry
