Site Preparation and Foundation: The Stage Most People Underestimate

Every new custom home construction project starts on the ground before it starts on the plans. Before a single ICF form goes up, your site needs to be ready. That means grading the land, digging the footings, and pouring the foundation. In Sheridan County, footings have to go below the frost line, which means four feet deep or more. That is not a guideline. It is what this ground demands after a real Wyoming winter. The foundation slab goes in after the footings cure. Everything that follows, every wall, every opening, every corner of your home, is built on top of that foundation. It has to be right.


This stage takes longer than most people expect and the site does not look much like a home yet. If you are building on rural acreage you may also be dealing with driveway access, well drilling, and septic during this same phase. If you are building from out of state, this is when having a builder who communicates clearly and manages the site on your behalf matters most.

The ICF Wall Phase: What Happens Before and During the Pour

This is the stage that makes a concrete home different from everything else. It is also the stage where the fire resistance, the wind protection, and the energy performance you researched get built permanently into your home. Not painted on. Not added later. Built in, during the pour, in a way that does not change. Foam forms are stacked into the shape of your exterior walls. Steel rebar is placed through the cavities at intervals your structural engineer has specified. Window and door openings are framed into the wall exactly where your design drawings show them. Then the bracing goes in to hold everything steady. Then the concrete is poured.


The pour is a single event. It cannot be paused once it starts. Concrete fills the wall from the bottom up in controlled lifts while the crew monitors it the entire time. When the concrete cures and the bracing comes down, you have a wall with a minimum 4-hour fire resistance rating. A wall engineered for wind loads up to 250 mph. A wall with R-26 plus continuous insulation and no thermal bridging anywhere. That wall is done. It is permanent. If you have watched a fire season come through this part of Wyoming, or opened an insurance renewal that made you stop and stare, you understand why this moment matters. The protection your family needs is already in that wall.

    One thing worth knowing before this stage begins: the location of every window and door opening is confirmed before the forms go up. In a standard framed wall, a mistake can be fixed with a saw. In a concrete wall, it cannot. Great Western Contracting reviews every opening location with you before stacking begins. That conversation is not a formality. It is how you make sure the view toward the Bighorns you planned for is exactly where it is supposed to be when the wall is done.

From Roof to Final Walkthrough: The Stage That Feels Like Any Great Custom Home

Once the concrete cures and the bracing comes down, the project moves fast. Roof framing goes up. Sheathing goes on. The building becomes weathertight. From this point forward, the build looks and feels like any well-run custom home. Windows go into the openings that were built into the wall during stacking. The view you planned for is now a real window in a real wall. Exterior cladding goes on, whether that is stone, stucco, board and batten, or siding. Inside, the mechanical, electrical, and plumbing rough-in happens. Then drywall, trim, cabinets, flooring, and all the finishes that make the home yours.


Most people who have never lived in an ICF home say the same thing after their first Wyoming winter in one. The house is quiet when wind gusts move through the valley. The temperature stays even without the furnace working hard. The heating bill is lower than what they used to pay. That is the wall doing exactly what it was built to do. Great Western Contracting does a full walkthrough with you before you take possession so you know every system in your home.

What to Expect From Your Build Timeline in Sheridan

A realistic home builder timeline of a Sheridan ICF project runs eight to fourteen months from breaking ground to final walkthrough. That range depends on the size of the home, the complexity of the design, how much site work the land requires, and the finish level inside. Site work and foundation typically take four to eight weeks. The ICF wall phase from stacking through cure runs two to four weeks. Roof framing and getting the building weathertight adds another two to four weeks. From there, the interior mechanical work and finishes run four to six months depending on the scope. Great Western Contracting gives you a realistic schedule estimate during the planning stage and stays in communication throughout so you always know where the project stands.


Concrete cannot be placed when temperatures drop below 40 degrees. In Sheridan County the reliable pour window runs roughly mid-April through October. A cold front in late October can push the pour date, which affects everything downstream. If you are coordinating a move-in date from out of state, this is one of the first scheduling details to understand. A realistic home builder timeline always has that weather margin built in. Great Western Contracting plans for it from the start and communicates any changes to you right away.

Building in Sheridan County Means Planning for Real Conditions

The custom home construction process Sheridan County requires is shaped by real conditions. Frost depth here means footings go four feet deep or more. Rural road access on acreage affects when equipment can reach your property. Wind exposure on open lots affects how the wall is engineered. Wildfire risk shapes roofing and finish choices. Great Western Contracting has built across Sheridan, Big Horn, Ranchester, Story, Buffalo, Gillette, and Sundance. Those conditions are not surprises to this team.


If you are planning this build from another state, you need a builder who understands the local complexity and handles it on your behalf. You should not have to learn Sheridan County's frost depth or worry about whether a concrete truck can reach your lot. That is the builder's job. The custom home construction process requires should feel like something your builder carries for you, not something you have to manage from a thousand miles away. Great Western Contracting communicates clearly at every stage so you always know what is happening and what decision is coming next.

Frequently Asked Questions About the Concrete Home Construction Process

See some common questions and answers below, or call us at 307-667-0672. 

  • What is the full construction sequence for an ICF home?

    An ICF home build moves through three phases. First, the site and foundation work gets the ground ready. This takes longer than most people expect and does not look like much yet, but everything above depends on it being done right. Second, the ICF wall phase is when the concrete is poured and your home's fire resistance, wind resistance, and energy performance get built in permanently. This is the phase that makes a concrete home different. Third, once the wall is done the project moves into roof framing, windows, mechanical work, and finishes that look and feel like any well-run custom home. A solid home builder timeline ICF project moves through all three phases in eight to fourteen months depending on size and complexity. Great Western Contracting walks you through each phase and the decisions within it before the build begins.



  • How long does the ICF wall phase take?

    Form stacking on a typical custom home takes several days to two weeks depending on the size and complexity of the wall. Rebar placement, buck installation, and bracing add time before the pour can be scheduled. The pour itself is usually a single day for a residential project. Curing takes several days before the bracing comes down. The total wall phase from the start of stacking to a stripped and ready wall is typically two to four weeks. The key thing to understand is that changes to opening locations after the pour are expensive and structural. The preparation before the pour is what protects you from that situation. When it is done correctly, the pour is straightforward and the wall reveals itself exactly as planned. That reliability is part of what makes new home construction projects built with ICF worth the planning investment.


  • What weather conditions affect the build schedule in Wyoming?

    Temperature is the main factor for new home construction projects built with ICF. Concrete placement requires the mix and the ambient air to be above 40 degrees Fahrenheit during placement and through the early curing period. In Sheridan County that reliable window runs roughly mid-April through October. A cold front that arrives in late October can push the pour date, which affects everything downstream. Great Western Contracting plans the pour date with buffer built in and communicates any weather-related changes to you immediately. If you are coordinating a move-in date around the build, the pour window is one of the first scheduling details to establish during the planning stage.


  • How do I stay informed if I am building from out of state?

    Each stage has its own communication rhythm. During site work and foundation you want to know when the footings are poured and when the slab is ready. During the ICF wall phase the pour date is the most significant event in the whole build and you should hear the result the same day the bracing comes down. During the finish phase the updates shift to decisions and milestones, window delivery, mechanical inspection, drywall start. Great Western Contracting keeps you in that loop at every stage. Plenty of people have built with this team from another state and said afterward that they never felt out of the loop. That is the standard every project is held to.


  • When does the fire and wind protection actually get built into the home?

    It gets built in during the pour. The fire resistance rating, the wind resistance, and the continuous insulation are all properties of the concrete wall assembly itself. They are not add-ons. When the concrete cures, the wall has a minimum 4-hour fire resistance rating and is engineered for wind resistance up to 250 mph. Nothing about that changes over time. If you have been through a fire season in Sheridan County or watched a wind event move through the valley, you know why that matters. The protection is permanent. It is in the wall from the day the bracing comes down.
