Picking A Barn Contractor
So, before you select a builder, ask the prospective candidates:
When looking at the buildings take a level, a rafter square, a tape measure and a camera. Take photo’s of problem areas. Preferably inspect the building on a sunny day.

Picking A Barn Contractor
So, before you select a builder, ask the prospective candidates:
- How many barns the contractor has built in the last year.
- Find out if they have a regular crew and ask how long each of their employees have been with the builder. You don't want a guy with a new crew, you want experienced tradesmen.
- Ask how long it will take to prep the site and erect the building? Specify that this will be included in the contract.
- Ask to see at least two of their previous buildings, preferably the last two, and that you want to talk to the owners of those buildings, in private without the contractor following you around.
When looking at the buildings take a level, a rafter square, a tape measure and a camera. Take photo’s of problem areas. Preferably inspect the building on a sunny day.
Example Building Owner Q&A Ask the building owner
- Is he happy with the building?
- What would he have done differently?
- What needed to be re-worked?
- Was the job site kept clean and materials secured at the end of the day?
- Were the workers on time and respectful?
- Would he use the contractor again for a building or renovations?
- Was the project on budget?
- Was the project completed on time?
Exterior of building. Look at the exterior steel for:
- scratches in the steel?
- scratches close to the screws that hold the steel to the buildings?
- visible jagged cut steel at edges or smooth?
- are the screws visually in a straight line as you site horizontally along the building?
- are the overlapping panels flush, or are there gaps?
- soffit panels flat and smooth?
- rake and soffit fascia flat and smooth?
- ridge cap flat across top of building or wavy?
- look at the trim around overhead doors and man doors for scratches and dents or jagged edges?
- Seamless gutters?
Inside the building
- What grade lumber was used (it will be factory marked on the sides of the boards)
- Check to see if the columns are plumb.
- If the columns are laminated, are the individual boards of the column tight? Nails or screws fastening the ply’s together? Nail spacing uniform?
- How are the columns attached to the headers and/or trusses? Through bolted, truss lock screws, lag screws or nails?
- Check to see if the girts are level.
- Is the lumber straight or bowed?
- Does the lumber have excessive amounts on knots?
- Can you see cracks in the boards?
- Can you see screws or nails sticking out of boards?
- Can you see screws that attach the steel to the building that missed girts or door / window surround boards?
- How are the girts attached to the support columns? Are boards splintered at nail locations?
- Are saw cuts square and straight? Check with your rafter square.
- Turn the lights off in the building and look for sunlight shinning in through gaps / holes.
- The splash boards at the walls, at the concrete to wall junction, at ground level, are they pressure treated?
- Is the concrete finish smooth? Too smooth? Not smooth enough?
- Can you see aggregate rocks in the concrete around the edges near the walls?
- Are there control joints cut in the concrete? Measure how far apart they are.
- What type of man door is used? Steel, vinyl, wood?
- Close the man door firmly. Does the wall shake? Does the door hang up on the door frame or close smoothly? Check that the door is level and plumb.
- What type of windows are used? Good quality vinyl clad energy efficient?
- Open and close the windows. Do they operate smoothly? Do they lock easily? Check that the windows are level and plumb.
- What type of overhead door(s) are used? Good quality, insulated, energy efficient?
- Open and close the overhead door(s). Do they operate smoothly? Do they lock easily? Do they have vinyl weather stripping? Check that the door frames are level and plumb.
- Are you planning to finish the walls and ceiling? Did you discuss this with the contractor? Look @ the wall girts and trusses, they can be designed / oriented such that the interior can be finished easier.
Leveling the site
- What equipment will be used?
- If they add fill material, what will fill materials will they use? Material from a local aggregate processor that has known properties or what?
- Will they compact the fill material?
- What height / thickness of fill do they add before they compact the fill? 4”, 5", 6”
- Will they add / compact / add in multiple lifts?
- What elevation will the slab be? Make sure the construction drawings show the final elevation that is relative to a fixed undisturbed point at the building site.
- Do they test for proper compaction? If yes, how and to what standard?
Support Columns (poles)
- What are the columns made of?
- Are they laminated columns or solid dimensional lumber?
- If laminated are they glued and nailed? What standard is used for the nailing pattern?
- If pressure treated wood, what grade of lumber and what CCA level?
- Ask how they dig the holes for the support columns.
- Do they compact the soil in the bottom of the hole if they are adding soil to adjust level height? If so, how do they compact that added soil?
- Do they place a precast puck in the bottom of each hole?
- Do they compact soil around the post as it is being filled back up?
Concrete Slab
- What elevation will the slab be? Make sure the construction drawings show the final elevation that is relative to a fixed undisturbed point at the building site.
- Ask when the slab will be poured, early in the construction or near the end?
- Ask how they prepare the sub-grade for the concrete slab. Tell them you are likely going to have a density test performed before the slab is poured (Even if you're not).
- Ask what concrete thickness and what concrete strength will be used. Tell them you want to see a mix sheet for the concrete they are proposing to use and that you will inspect the mix sheets for every load that arrives on site and you shall approve it before it is used.
- Ask if they follow American Concrete Institute (ACI) standard practices.
- Ask if they will follow ACI “Cold Weather Concreting” standards.
- What reinforcing steel will they use? If they are using mesh or rebar what type, diameter, and spacing?
- If they use mesh, are they using sheets or rolls? Do they use wire ties to secure the re-bar / mesh? Do they overlap the re-bar / mesh at seams?
- Will they use dobies or chairs to properly locate the reinforcing steel?
- Will they also use fibre mesh, in addition to reinforcing steel?
- Will they cut the control joints within 12 hours?
