Tour of the Simplex Modular Home Factory

In this segment, Bob continues his tour of the Simplex Industries manufacturing facility. The plant workers are precutting all the plywood for the project house, as well as other homes currently in production. The efficiencies created by using large industrial saws to make precision cuts save the homeowner time and money and insures a well-fit house. Dave Boniello from Simplex guides Bob through the cutting area of the plant. Unlike most site-built homes, all of the scraps of wood are sent back to the manufacturers for recycling. Continuing the tour, Boniello and Bob overlook the construction of the interior and exterior walls, which are built in sheets of varying heights (up to 10 feet) and up to 64 feet long. Modular homes are built from the inside out, meaning that instead of starting with the exterior framing, roof and sheathing, the modular home starts with interior walls and drywall. The wallboard is glued and screwed to the stud walls, which have additional steel plates to maintain rigidity during transport. Bob points out the inspection process for a modular home is different than for a site built home as local inspectors would be hard pressed to visit the Simplex plant in Pennsylvania. Simplex hires independent inspectors that are certified in multiple states and they correspond with local building inspectors to insure that all building codes are met or exceeded.

" We're touring the plant here with Dave Boniello, who is the Vice President of Marketing. And this looks like pretty traditional work that they're doing here, ripping down sheets of plywood, but boy, we're out of the weather."

" Oh it's great, Bob. What we're doing here is, we have parts list that are, that come down from my Engineering Department that give these guys a work list of they're days work and they're basically taking all different sized plywood, half a 3 quarter cutting it to the sizes and the quantities that are required. Putting it on buggies and shipping it over into other departments."

" Okay."

" And again it's great. It's out of the weather and there's no [unk]."

" What happens with all the waste?"

" Well, we have a strict recycling program. We work with our lumber suppliers on lumber and plywood and a lot of that stuff is putting buggies and shipped back to them when they're delivering us material."

" So it's recycled?"

" Yes."

" Tell me something, there's so much lumber, how do you keep track? I mean, how many houses are being built at one time?"

" Well, in the entire building Bob, we're working on anywhere from 8 to 10 houses a day and these guys could be generally cutting lumber for 1 to 2 houses at a time."

" Wow. Let's talk about the framing table. There are 2 platforms here that are, how long?"

" Well, we're building walls anywhere from 30 to 64 feet generally for any of the houses we built."

" Yeah."

" So, they're quite large walls."

" Yeah."

" And table here is usually the outside wall which is always a 2 x 6 wall for our products and then the mating wall or the marriage wall as we call it, which could be a 2 x 3 or a 2 x 4 wall is generally built on that other large table over there."

" Okay. So is the box always the same height?"

" No. We're building 8 foot ceilings, 9 foot ceilings. We've even gone as high as, built some things with 10 foot ceilings."

" Well, our particular house has a high ceiling in some sections."

" It's a custom box and it's not 10-foot high stud but it's very unique studding."

" Right."

" So just like on a regular job, they lay everything out. They put all the studs on 16-inch centers."

" Typically, Bob, we're building products for different market places and we do build 16 and 24 on center products. We are flexible depending on the market place for building."

" Now, Dave, what's the purpose of all the metal that's stapled on here."

" Again, it's something you need for our industry, Bob. What we're doing here is we're putting metal plates on the headers and tying to the jack in full stud and again on the sill, tying it to the jack and full stud. And the beauty of this is it's gonna help prevent any stressing and pulling in the transportation and the setting of the units that could add to dry wall cracking."

" Great."

" So this is unusual, we're actually putting the dry wall onto the surface of the stud wall at this stage."

" Yes Bob, again, it's something unique for our industry. What we do is, we actually build a house from the inside out and in the stick-build industry, you build a house, you frame it and sheathe them from the outside in."

" Yeah."

" But we're gonna place the dry wall on again. It's on the table. The wall's been squared up and then we'll place the dry wall on top of the studs and screw it down. It's actually glued and screwed down."

" What kind of adhesive is it that you're using?"

" It's a PL200 adhesive."

" Okay. Well, it's pretty impressive the speed at which they're working around here and of course the dry wall screws are mounted in this magazine and the air guns just put them in there, very quickly. Now, you're just reaching a point over here where you got a window opening."

" Right."

" And, I guess, 2o things, do you sheath right over it and then cut it off?"

" Yes, we will, Bob. We'll actually sheath over the entire wall, take a router with a cutting bit on it and just get a nice clean cut around the windows."

" Uh-huh."

" Now, this is pretty impressive. You've just basically put in these big eyebolts in here so that you can crane the thing away."

" Exactly."

" So what happens next?"

" We pick it up with a hoist and we bring it up and we store it over into that wall storage."

" And then tomorrow they'll be put together."

" They'll be picked up again and hoisted over onto the assembly line and drop down on top of the floors."

" Right. It takes some good planning."

" Alright. Now Dave, we're basically looking at the assembly process here where you're putting the brief manufactured walls together to create a box. What's the first step?"

" Well, the first step like anything else is starting with the floor system and were building basically a rectangle, sometimes with some odd cut-outs in it but basically it's a rectangular floor and we'll frame it out of either 2 x 8's or 2 x 10's depending on the framing designation for that, Bob."

" I like this term marriage wall. This is---- since were putting together a separate boxes wherever the boxes are joined together, you call it a marriage."

" Marriage wall or the mating wall. Yes."

" Now, what about the roof frame?"

" We're building our roof systems on a table and we're basically putting the dry wall face down and framing on top of that."

" Let me ask a question about inspectional services. I mean, if you're selling manufactured houses in Massachusetts, how do they sign off on wiring and plumbing and the like?"

" Well, that's a great question. I mean, the building inspector isn't able to come here to the factory and check the boxes out, so we use an independent third party system. It's unique in our industry. It's done and it's accepted in all states and that third part is basically reviewing our plans and then taking the plans out onto the production line and making sure that the boxes are built in accordance to the plan which they review and they approve."

Building a Modular Home
Building a Modular Home

Bob meets with Pat Fricchione from Simplex Industries of Scranton, Penn. to discuss the modular home industry and specifically the home being built in western Massachusetts? Berkshire Hills. Simplex delivers homes all over the Northeast and Mid-Atlantic states. Today?s modular homes are designed to meet the needs of the modern discriminating homebuyer. The materials used in a modular home are essentially the same as those used in a site built one. They can be customized or built from existing floor plans. The homeowner gets the advantage of buying in bulk for all the materials in the home. And its always perfect weather in the factory, so there are no delays due to rain or snow. A typical home can be built in a week at the factory and delivered to the home site in ready-to-assemble pieces.

Delivery and Installation of the Modular Home's Second Floor
Delivery and Installation of the Modular Home's Second Floor

Bob Vila oversees the delivery and installation of the first section of the second floor of the home. Bob points out the complexity of this piece with its dormers and gable roof. The modern modular home can be conformed to the homeowner?s desires. The second floor in this example has an exterior egress, which will eventual permit the owner to walk out onto a small terrace over the first floor dining room. In Simplex modular homes, the ceilings of the first floor are manufactured separately from the floors of the second story. This separation of shared framing timbers reduces the noise transfer from one floor to the next. This is especially advantageous in multi-family dwellings and business structures.

Modular Home Construction Basics
Modular Home Construction Basics

In this segment, Bob Vila visits the Simplex Industries modular home plant in Scranton, Pennsylvania, where the Home Again project house is being constructed. Dave Boniello, the Vice President of Marketing for Simplex, gives Bob a plant tour during the construction of the Modular Mountain Retreat project house. Building the majority of a home in a factory and delivering it to the home site to be assembled presents unique challenges. Simplex Industries, a privately owned company that ships over 400 homes a year, utilizes a mix of traditional framing techniques and modular home construction-specific practices to ensure that the transportation of the home from factory to building site can be accomplished without structural or cosmetic damage to the house. Examples include eaves that can be folded up for transportation, extra bracing between walls and floors, metal shielding to protect rough electrical work, and drywall that is glued, not screwed, into place.

Prefinished Wood Floors in the Modular Home
Prefinished Wood Floors in the Modular Home

Bob Vila takes an early interior tour of the modular home. Bob is in a 15-foot-wide-by-48-foot long section. The flooring and walls are almost complete and much of the molding and cabinetry is laid out and ready to be installed. Bob points out an archway between the kitchen and breakfast nook?one of the pleasant design surprises that can be added to a custom modular home. The floors are Bellawood?s Northern Red Oak with a gunstock finish. The darker finish gives a more sophisticated and formal look to the room. The hardwood floors are installed in the modular home just as they wood be in a site built home. Mike Snyder from Mike?s Flooring, a flooring sub contractor in the Simplex plant, points out the quality of the Bellawood noting it has very few flaws and a durable finish. The flooring is left incomplete where two pieces of the modular home are to be attached. On site, quick work will be made of the few details left when the large modular sections are joined.
