How Long Does a Patio or Outdoor Living Project Take?

A simple patio at grade is days on site, and a multi-element project is weeks or longer, but the time before the first shovel often matters more.

The unglamorous stages take the longest, and they are the ones people mentally skip when they imagine the job. Most of a patio's time on site is spent below finished level: digging, placing base in lifts, compacting, checking, and setting the falls. The pavers going down is the quick part.

Permitting, weather and undecided choices, in roughly that order. Very little of it is time on site.

Permitting. Fayetteville is the strictest jurisdiction nearby. A grading permit is triggered by the Hillside/Hilltop Overlay, a floodplain, slopes of 15 percent or more, or a retaining wall over four feet, and the plan must be sealed by an Arkansas-registered engineer, landscape architect or architect. Bentonville requires an engineer and a permit for walls over four feet. Bella Vista adds a second approval, because the POA's Architectural Control Committee reviews separately from the city.

Weather. Earthwork on saturated ground does more harm than good, so a wet week is a lost week. That is not a contractor being slow, it is a contractor not building your patio on mud.

Decisions. The most common delay of all is a material, colour or layout choice that has not been made. Deciding early is the cheapest way to shorten a project.

Spring and autumn are the prime building windows here, winter is workable in dry spells, and summer is fine except for the heat and the storms.

National Weather Service records for Fayetteville's Drake Field put the average last spring freeze around April 16 and the first autumn freeze around October 19. Hard freezes of 28 degrees or colder average early April and early November. The 1991 to 2020 normals show the average overnight low at or below freezing through essentially all of December, January and February.

Freezing matters because ICPI's construction standard says base aggregate should not go down on a frozen subgrade and frozen material should not be installed. Mortar and concrete work have their own cold-weather limits. A crew that stops on a hard-frozen morning is following the standard.

Rain matters more than cold. The same normals put average yearly precipitation at nearly 47 inches, and spring storms can leave clay too wet to work for days afterwards.

Yes, in dry cold. What stops the work is saturated or frozen ground, not the number on the thermometer.

A dry, cold week in January can be ideal for excavation and base work. The ground is firm, machinery does less damage to the lawn, and the crew is not working through the heat of July. What does not work is placing base on frozen ground or compacting saturated clay, which is why winter schedules move around more than summer ones.

Winter is also when a lot of the work that is not weather-dependent gets done: design, decisions, permit applications and engineering. Starting that in December is how a project breaks ground in March rather than June.

Summer brings its own limits. Heat slows crews in the middle of the day and affects how concrete and mortar cure, and sudden storms can soak an open excavation in an afternoon. A good crew protects open ground at the end of each day and plans concrete pours for the cooler hours, which is part of why summer jobs are not always faster than spring ones.

Scope drives time more than size, because each new element adds a trade, a cure time or an inspection.

A patio at grade on an accessible lot is the quickest job on this list. Add a seat wall or a fire pit and you add masonry and possibly a gas line. Add a retaining wall and you may add an engineer and a permit. Add a covered structure and you add footings, framing, roofing and inspections. Add a pool and the deck cannot finish until the pool shell and its backfill are complete.

Access changes things too. A back garden that machinery can drive into is a different job from one where everything goes through a side gate by hand, and on some of the older streets around the squares in Bentonville and Siloam Springs, that is the reality.

Rock is the other variable. On the Springfield Plateau, finding limestone or chert a few inches down changes the excavation method, and that is time as well as money.

A patio build follows the same sequence every time, and knowing it helps you read progress and spot a skipped step.

1. Layout. The outline is marked, utilities are located and levels are set.
2. Excavation. Soil comes out to the planned depth and is hauled away. Rock, if it is there, shows up now.
3. Subgrade. The bottom is shaped to the fall and compacted, and soft spots are dug out and replaced.
4. Base. Aggregate goes in lift by lift, compacted and checked each time.
5. Edges and drainage. Edge restraint, drain pipe and any channel drains are set.
6. Bedding and surface. Bedding sand is screeded, pavers or stone are laid and cut.
7. Joints and compaction. Joint sand is swept in and the surface is compacted.
8. Clean-up and reinstatement. The site is cleared and the access route is put right.

Steps two to five take most of the time. If the pavers start going down very soon after the digging stopped, ask how the base was placed.

Make decisions early, keep access clear and let the contractor handle the approvals.

Pick materials, colours and appliances before the start date, and put them in writing. Changes after work starts almost always cost time, because materials have to be reordered and work already done may have to be redone.

Clear the access route: move vehicles, open gates, and let neighbours know if machinery will pass close to their side. Mark anything buried that you know about, such as irrigation lines, invisible dog fences or garden lighting, because the public utility locate will not find private lines.

If you are in Bella Vista, start the ACC application alongside the design, not after it. The ACC works to its own schedule, and approval from the city is not approval from the ACC.

In winter. By spring the schedule is full, and in Fayetteville and Bella Vista the approvals alone can take longer than the build.

If you want to be using the garden in June, the conversation should happen in December or January. That gives time for a site visit, a design you are happy with, decisions on materials, permit applications and any engineering, and a start as soon as the ground allows.

Winter is also when good contractors have availability. By April everyone competent is booked, and the people with immediate availability in May are available for a reason.

In total calendar time, yes. In disruption at any one time, no, and that is often the point.

Phasing is a legitimate answer to a budget or a tight timeline, provided the whole scheme is designed up front. The rule is that ground work, conduit, gas and footings for future elements go in during phase one, so later phases do not mean digging up finished work.

Done that way, phase two can be a quick fit-out rather than a second construction project. Done without a whole-scheme design, it usually means lifting paving that was only laid a year before.

Both sit outside the crew's control, so a good schedule leaves room for them.

Permitted work gets inspected at set points, typically footings before concrete, framing on a covered structure, and services before they are buried. The work stops until the inspector has been, and inspectors keep their own diaries. A contractor who schedules around those visits keeps the project moving; one who does not ends up with a crew standing idle.

Material lead times are the other outside factor. Stock pavers in common colours are usually quick to get. Specific large-format units, natural stone, built-in appliances, louvred roof systems and custom metalwork can take much longer, which is another reason to make decisions before the start date rather than after it.

Bentonville's right-of-way permit, needed for any work in a street, curb or sidewalk, carries a five-business-day review on its own. Small items like that add up if nobody plans for them.

A realistic schedule gives a start window rather than a start date, names what can move it, and sequences the stages in order.

Expect something like: site visit, design and decisions; permits and approvals submitted; start window; excavation and base; structures; surface; services and fit-out; inspections and walk-through. Each stage should show what it depends on, especially the ones that depend on a city or a POA.

Be wary of a schedule that promises a fixed start date in spring without any mention of weather or permits. Nobody controls either. A contractor who says so is being straight with you.
