Hiring an Engineer is Terrible Advice?

Registered Design Professionals and Building Officials please weigh in on this one. Is hiring an engineer terrible advice?

In a Facebook ‘Barndominium Living’ discussion group this was posted:
“Curious as to how many of you consulted an engineer before building (for concrete and steel framing) or simply went with your welder’s design?”

First response, from a fellow group member, was:
“Most metal building manufacturers have engineers on staff as part of the design process.”

Original poster replied:
“Yes, when getting quotes directly from them we understood it would have an engineered stamp. We have chosen not to do bolt up, so the welders we have talked to would just order the metal and do their own design.”

Here is where I stepped in:
“Regardless of what type of building system you decide upon, please please please have plans sealed by a Registered Design Professional (architect or engineer).”
Now this next poster may be suffering from Dunning-Kruger Effect (poor grammar in his post left for lack of clarity) (https://www.hansenpolebuildings.com/2015/01/dunning-kruger-effect/):
“That’s some terrible advice you have given here. Plenty of builders that do a great job without the extra cost of a architect or engineer.”

My retort went something like this:
And why would it be terrible to insure every component and connection meets structural requirements? A building is only as strong as its weakest link and unless this “great job” builder is capable of running all structural calculations for a particular building, there exists a possibility of an under design.

There are also insurance companies giving discounts for having an engineered building.
I am not a RDP and I make no money promoting use of them. I do care deeply about properly structural designed buildings – any failure, especially of a barndominium to be used as a home, makes all of us – even those who do it right look bad.
Hopefully this article will generate some thoughtful responses.

Barndominium Costs Part II

Continuing my discussion of Barndominium costs from yesterday’s blog…
For sake of discussion, we will use 2400 sft (40×60) of finished living space (includes any bonus rooms) plus 1600 sft of garage/shop. To have a GC (General Contractor) turn-key this for you expect an average of:

2400 X $122.46 = $293,904
1600 X $61.56 = $ 98,496
$293,904 + $98,496 = $392,400 / .6977 = $562,419

This is having your barndominium built (turn key), not for owner-builders.
If your barndominium will be very simple, rectangle, standard sizes, with little to no upgrades on finish materials (counter tops, flooring, cabinets, showers, lighting, trim, etc) then your costs could be less per sft.

 

On spectrum’s other end would be for very intricate, high end, everything upgraded barndominiums. Including things like custom cabinets, real hardwood flooring, high end appliances, custom fireplace, built in entertainment options, oversized windows and doors, vaulted ceilings throughout, steep roof, extra bathrooms/kitchens, etc.

But what you really want to know is what it will cost for you to build it, right?
We will assume you are willing to do some legwork, so if you don’t do any physical work yourself and just act as general contractor (making phone calls, hiring people, ordering materials, dealing with problems, etc) you can build this average barndominium for $170,000 less than it would cost to hire a general contractor.

I can make a LOT of phone calls for this. In fact, I could easily take well over a year off work and still come out ahead!

Beyond making phone calls, hiring people, ordering materials, and dealing with problems, you can lower your price by doing some work yourself.
It’s all about what YOU are willing to do as an owner-builder.

Our prices above are for “stick frame” construction. By using post frame construction with embedded columns, rather than pouring a footing and foundation, a savings of $11,400 can be found: https://www.hansenpolebuildings.com/2011/10/buildings-why-not-stick-frame-construction/.
This reduces your $392,400 investment by about 3% to $381,000
NAHB (National Association of Home Builders) allocated percentages in their Construction Cost Breakdown. These included:

Site work 5.6% (of this 1.6% was for architecture and engineering)
Foundations 11.6% (this includes excavation and backfill)
Framing 18%
Exterior Finishes 15% (siding, roofing, windows, doors)
Plumbing, Electrical, HVAC rough ins 13.1%
Interior Finishes 29.6% (insulation, drywall, interior trims and doors, painting, lighting, cabinets, counter tops, appliances, flooring, plumbing fixtures, fireplaces)
Final Steps 6.8% (Landscaping, decks, driveways, clean up)

Of framing and exterior finishes (roughly 1/3rd of costs), if you invest in an engineered post frame building kit package and do your own labor (labor being roughly 1/3rd of this portion), save $43,164 (I can take a lot of time off work for this).

Hansen Pole Buildings GuesthouseAnd my engineered post frame building kit package includes engineering, saving $6278.
Obviously even more savings can be achieved for those capable of doing electrical and plumbing, however assuming nothing other than what has been listed, your $562,419 barndominium has been built and is ready to move in for $331,558!! This resulted in over a 41% savings and kept over $230,000 in YOUR pocket!!

Of course your investment and savings could be more or less depending upon your tastes and location, however this should give you a feel for where you will be headed. It would be prudent to budget another 1% for every month you delay your start, as well.
