Pool Construction SchedulePhases, Timeline & How Long a Pool Takes
October 8, 20269 min readBy the Ardovia team
Building an in-ground gunite or shotcrete pool typically takes about 8 to 12 weeks of construction once permits are approved, plus anywhere from a couple of weeks to a few months beforehand for design, HOA, and permits. The build runs in a fixed order — layout, excavation, steel, plumbing, shotcrete, tile and coping, equipment and electrical, decking, interior finish, and start-up — with inspections between key phases. Durations vary widely by region, permit office, weather, and design.
How long does pool construction take?
For a typical residential gunite or shotcrete pool, the on-site build usually lands somewhere in the 8–12 week range. A simple pool with a small deck can finish faster; a pool with a spa, water features, retaining walls, or a large outdoor living package can take considerably longer.
The bigger variable is often what happens before the first shovel. Design approval, HOA review, engineering, and permitting can take a couple of weeks in some jurisdictions and several months in others.
Treat every number in this guide as a rough planning range, not a promise. Your local permit office, inspection availability, soil, weather, and crew capacity will set your real timeline.
Pool construction schedule template (typical durations)
Phases in build order for an in-ground gunite or shotcrete pool. Durations are typical working-day ranges for planning; they vary by region, permit office, and design.
| # | Phase | Typical duration | Depends on / inspection |
|---|---|---|---|
| 1 | Design, contract & selections | 1–4 weeks | Signed contract and deposit |
| 2 | Engineering, HOA & permits | 2 weeks – several months | Varies most by jurisdiction |
| 3 | Utility locate & layout | A few business days | 811 request; permit issued |
| 4 | Excavation | 1–3 days | Layout approved by owner |
| 5 | Steel & forming | 2–5 days | Excavation; steel inspection often required |
| 6 | Plumbing | 1–3 days | Steel; pressure test and plumbing inspection where required |
| 7 | Pre-shotcrete inspection | 1–5 days to schedule | Steel, bonding, and plumbing complete |
| 8 | Shotcrete / gunite shell | 1 day to apply | Passed pre-shotcrete inspection |
| 9 | Shell cure | About 1–2 weeks before heavy work | Follow your engineer and applicator |
| 10 | Tile & coping | 3–7 days | Cured shell |
| 11 | Equipment set & electrical | 2–5 days | Plumbing and pad; electrical inspection |
| 12 | Decking | 3–10 days plus cure | Coping; deck forms and bonding inspection where required |
| 13 | Barrier / fence & final inspection | 1–2 weeks to schedule | Code-required barriers in place |
| 14 | Cleanup & interior finish | 1–3 days | Deck and equipment complete |
| 15 | Fill, start-up & owner walkthrough | 1–2 weeks of start-up care | Interior finish applied |
Durations are general planning ranges, not guarantees. Inspection requirements and order differ between jurisdictions — confirm with your permit office.
Step by step
Pool construction phases, step by step
Here is what happens in each phase and what it needs before it can start.
- 1
Design, contract, and selections
The customer approves the design, signs the contract, and pays the deposit. Lock as many selections as you can now — tile, coping, finish, and equipment — because late selections are a common cause of mid-build delays. See our pool proposals and selections page.
- 2
Engineering, HOA approval, and permits
Most jobs need an engineered plan and a building permit, and many need HOA approval. Submit as soon as the contract is signed. This is the least predictable phase, so do not promise a start date until the permit is in hand.
- 3
Utility locate and layout
Request a utility locate through 811, the free national before-you-dig service, which asks you to contact it a few business days before digging. Then paint the pool outline and confirm the layout, elevation, and equipment location with the owner.
- 4
Excavation
The dig itself is usually quick. Rock, groundwater, tight access, or soil haul-off can add days, which is why those items belong in your contract exclusions or as priced contingencies.
- 5
Steel and forming
Crews set forms and tie the rebar cage per the engineered plan. Many jurisdictions inspect steel and bonding before shotcrete — build that inspection into the schedule as its own step.
- 6
Plumbing
Main drains, returns, skimmers, and lines to the equipment pad go in, and the system is pressure tested. Where a plumbing inspection is required, it usually happens before the shell is shot.
- 7
Shotcrete or gunite shell
The shell is sprayed and shaped in a day for most residential pools. It then needs to cure, typically with regular watering. Follow your engineer's and applicator's guidance on how long to wait before tile, coping, and heavy loads.
- 8
Tile and coping
Waterline tile and coping set the finished look of the pool edge. Material lead times matter here — order tile and coping early so they are on site when the shell is ready.
- 9
Equipment and electrical
The pump, filter, heater, sanitation, and automation go on the pad, and the electrician runs power and bonding. Expect an electrical inspection before the pool is energized.
- 10
Decking
Concrete, pavers, or stone decking goes in around the pool. Concrete decks need cure time before heavy traffic, and some jurisdictions inspect deck bonding or forms first.
- 11
Barriers and final inspection
Most jurisdictions require a code-compliant barrier — fencing, gates, alarms, or covers, depending on local rules — before final approval. If the fence is by others, coordinate it early so it does not hold up final.
- 12
Interior finish, fill, and start-up
The interior finish is applied, the pool is filled, and start-up begins: balancing chemistry and brushing, often daily at first. Finish with an owner walkthrough on equipment, safety, and maintenance.
Dependencies: why the order matters
A pool schedule is a chain. Shotcrete cannot go in until steel and plumbing pass inspection, tile waits for a cured shell, and the interior finish waits for decking and equipment. One late link pushes everything behind it.
That is why a pool construction schedule template should be built on dependencies, not fixed dates. When excavation slips two days, every later phase should move with it automatically, and your crews and customer should see the new dates.
Some work runs on calendar days, not working days. Concrete and shotcrete cure through weekends, so model cure time as elapsed days rather than crew days.
What delays pool construction?
Most delays fall into a handful of buckets. Plan for them in both the schedule and the contract.
- Permits and HOA review: the single biggest variable, and outside your control.
- Inspections: waiting for an inspector, or a failed inspection that needs a fix and a re-inspection.
- Weather: rain stops excavation, shotcrete, and decking, and wet ground can add days after the rain stops. Extreme heat or cold affects concrete and finish work.
- Site conditions: rock, groundwater, poor soil, or access problems found during excavation.
- Late selections or changes: a customer who has not chosen tile, or adds a feature mid-build, can hold up a whole phase. Document changes with a change order.
- Material lead times: tile, coping, equipment, and specialty items that are not on site when the crew is ready.
- Payment gates: if your draws are tied to milestones, a late payment can pause the next phase.
How to communicate the timeline to homeowners
Homeowners mostly want to know two things: when you will start, and what happens next. Give them the full phase list up front, with ranges instead of exact dates.
Explain that the clock really starts at permit approval, and that inspections and weather can move dates. Update them at each milestone, especially when a phase completes and the next one is about to begin.
Put the estimated duration and the factors that can change it in your proposal. Our construction proposal template includes example timeline wording.
Building your schedule template in Ardovia
Ardovia's construction scheduling lets you build a reusable schedule template on a Gantt chart — phases, tasks, inspections, payment requests, and customer emails connected by dependencies with lead or lag days. Apply it to a job and dates resolve from the contract date on your working calendar, with blackout dates; items like concrete cure can be set to run on non-working days.
When an item finishes early or late, the items waiting on it move with it. Permit inspections can be placed on the schedule from the permit and set to hold up the next phase until they pass, and templates remind you to include an 811 dig request. Draw sections can act as payment gates. See how this works for pool builders.

Frequently asked questions
How long does it take to build an in-ground pool?
A typical in-ground gunite or shotcrete pool takes roughly 8 to 12 weeks of construction once permits are approved. Design, HOA approval, engineering, and permits can add anywhere from a couple of weeks to several months beforehand. Pools with spas, water features, or large decks take longer, and timelines vary by region, permit office, and weather.
What are the phases of pool construction?
The usual order for a gunite or shotcrete pool is design and contract, engineering and permits, utility locate and layout, excavation, steel and forming, plumbing, inspections, shotcrete shell, cure, tile and coping, equipment and electrical, decking, barriers and final inspection, interior finish, and fill and start-up.
How long does excavation take for a pool?
Excavation for a typical residential pool usually takes one to three days. Rock, groundwater, poor soil, tight access, and soil haul-off can extend it. These conditions are often listed as exclusions or priced contingencies in the contract because they are hard to predict before digging.
What causes the most delays in pool construction?
The most common delays are permit and HOA approvals, inspection scheduling and re-inspections, rain and weather, unexpected site conditions like rock or groundwater, late customer selections or changes, and material lead times. Building the schedule on dependencies, rather than fixed dates, makes it easier to re-plan when one of these hits.
Do pools need inspections during construction?
Most jurisdictions require inspections during pool construction, commonly for steel and bonding before shotcrete, plumbing, electrical, and a final inspection that often includes the safety barrier. Requirements and order differ by jurisdiction, so confirm them with the local permit office for each job.
