Today’s Objective

Clearly define modular housing Present the benefits of modular

housing Review the modular housing process Examine some “lessons learned” in

modular housing

Modular Housing Defined

A structure designed primarily for residential occupancy, designed and constructed to a state or national model code, which is manufactured in one or more sections in a factory for installation on a permanent foundation at its final location.

Modular Housing Defined

The term does not include manufactured housing as defined by the National Manufactured Housing Construction and Safety Standards Act of 1974 (42 U.S.C.A. §§ 5401-5426).

What Modular Is Not: Mobile Home

A movable or portable dwelling built on a chassis, connected to utilities, designed without a permanent foundation, and intended for year-round living

What Modular Is Not: Manufactured Home• A structure, manufactured in one or

more sections, which is built on a permanent metal chassis and designed to be used as a dwelling with or without a permanent foundation when connected to utilities and includes plumbing, heating and electrical systems, manufactured in accordance with federal standards under the National Manufactured Housing Construction and Safety Standards Act of 1974 (42 U.S.C.A. §§ 5401-5426).

What it Is- Modular Homes Built to International or State Building

Code Built in a factory Installed on a permanent foundation Shipped to site on trailers, set with crane An appreciable asset Appraised the same as site built (same

comps) Generally stronger, more energy

efficient, faster to build, and less costly to build

Modular and Affordability Some General Assumptions

Things to Consider

Site Conditions? Site Access? Single Home or Multi-home

subdivision? Lot orientation and design

relationship? Is time a critical consideration? Do I have green requirements?

When to Use Modular

When time is money When labor is unavailable or cost

prohibitive When volunteer labor is available When multiple units enable “quantity

discounts” When site conditions and access permit When you can easily apply standard

designs

When Not to Use Modular

Difficult to access sites When modular shipping is cost

prohibitive When additional site work is required to

support modular handling Sites that allow ‘slab on grade’

construction When surrounding features complicate

the set process (trees, power lines, adjacent structures)

When Not to Use Modular

Modular Advantages

Built stronger than most site built homes

Material efficient HBH and LEED points for material

conservation due to recycle Energy Efficient

Better air sealing than most site built homes Third party inspection for Energy Star

More design flexibility than ever before

Low Cost/High Value Specifications

Low/No VOC materials Zero formaldehyde insulation Icynene or open cell foam High efficiency water heaters Select flooring finishes (save on site)

Laminates, hardwoods, vinyl tile Attic storage space (storage truss) Bonus Space!!

Modular with Icynene

On-Site Completion

Foundation and site works Electric meter base (and disconnect) HVAC system installation (mfg specific) Condensing unit/air handler electric Electric and water junctions Drain and vent line completion Marriage wall finishing Connection to services

(water/waste/electric)

Some Misunderstandings in Modular Construction

The manufacturer is NOT a GC The specifications ARE the home Modular homes are not suited to on-

slab construction The GC (typically) orchestrates set

crew, road transport, site transport (dozer, tug, jade), crane services, and set crews

The GC can complete, or enter in to “owner completion” contract

The Modular Process

1. Site Assessment Access? Trees? Power/phone lines?

Other Properties? Site Works?

2. Design Selection Can you select an existing design to meet

you site and client needs

3. Identify an experienced, reputable contractor with experience in modular construction

Exclusive dealer or Independent GC?

The Modular Process

4. Determine your product needs and DOCUMENT

Energy efficient certification? System Vision? HealthyBuilt Home?

5. Determine your GC requirements Turn Key or Owner Completion? Who is

responsible for what tasks? Who is the selected manufacturer, and

how do you verify they can meet your specifications?

The Modular Process

6. Generate your specifications and contracts

Modular specifications Water heater? Insulation? Siding? Floor

finishes? HVAC? Certification requirements? E-Star? Zero VOC? Windows/Doors? Cabinetry/Countertops? High wind zones? Snow loads?

Site work and foundation specifications

7. Order your home, ready your site, and complete your house

Lessons Learned

Lessons Learned

Work with an experienced, reputable GC!

If it’s difficult to drive to your site, imagine pulling a 14’ wide, 14’ high, 50’ long, 30,000 lb box behind you!

Not all manufacturers are created equal If it’s not in the specs, it’s not in your

house Leased equipment and services begin

billing when they leave their shop

Pick a Reputable GC and Subcontrators!

More Lessons

There’s efficiency in quantity, value in planning

Try to use existing, standard designs Though changes don’t cost much, they

cost! You don’t want to move power or

phone lines- (intentionally or otherwise!)

Bridges and large trees are typically stronger than your home

If It Don’t Fit, Don’t Force It
