Follow our journey as River Vine’s modular prefab construction progresses from factory to site.

Excitement is building! River Vine's West Wing is wrapped and ready to be delivered!

Our final four modules are leaving the AMS factory tomorrow, headed for Lodi.

Escorted by the California Highway Patrol, our proprietary AMS transports hit the road, bringing the first River Vine modules from our Manteca factory home to Lodi.

Our delivery crew got an early start. The modules are loaded and secured on their trailers, covered in weatherproof wraps to protect them during shipping.

Our parallel construction process is highly efficient, allowing the River Vine modules to be built in our 300,000-SF AMS factory in Manteca while site development continues in Lodi.

USG gypsum panels were installed on ceilings and walls. Structural ceiling panels provide insulation, improve IAQ and maintain superior acoustics for greater occupant health and well-being.

The East Wing, Garage and Central Tower interiors are almost ready for finish work. The drywall’s up, Solatubes are operational, ductwork is installed and our crews are roughing in electrical.

Ductmate contractors installed and sealed the ProFlex high performance duct connector system. No-VOC duct insulation ensures quiet operation and enhances thermal values for optimal HVAC efficiency.

The Solatubes are in! Their unique design is more space-efficient than traditional skylights, but adds just as much light. Daylighting not only brightens moods; it can lower energy consumption and costs by 30%.

A supertight building envelope is vital to River Vine’s performance. Gypsum-fiber roof boards from USG are exceptionally strong and durable, making the home’s low-slope roofing system weathertight.

Three Heliodyne solar flat-plate collectors were mounted on the garage roof. Positioned to face south, they’ll maximize the heat collected from the sun and use it to power River Vine’s solar hot water system.

Geothermal energy transferred from underground will be delivered through Aquatherm Blue Pipe installed in the interior walls. Integrated with the radiant flooring system, it will heat and cool all areas of the home.

Our plumbing crew installed Aquatherm Green Pipe for domestic water use. Green Pipe is chemical- and toxin-free, making it a safer, cleaner option for drinking water and food preparation.

The module exteriors are fully wrapped and insulated, watertight and airtight from top to bottom. Now we’ll start insulating the interiors.

Since River Vine has a structural steel frame, we insulated the exterior walls with USG’s glass-mat sheathing to counteract thermal bridging—the flow of heat through walls, ceiling and floor.

The fiberglass coated sheathing creates a noncombustible air/water barrier that reduces heat loss in winter and heat gain in summer, keeping River Vine more comfortable and energy-efficient year-round.

The final step in our high performance building envelope system is VaproShield WrapShield, a self-adhered breathable membrane that protects the building from moisture and contaminants.

A total of 16 modules will be joined seamlessly on the concrete foundation, forming a 4,000-SF building that looks like it was stick-built on site. Each module is 10’ - 16’ wide, with a maximum length of 45’.

Steel walls and headers are bolted to our moment frame. The strength and ductility of structural cold-formed steel (CFS) framing and the holding power of CFS connections are ideal for California’s seismic zones.

River Vine’s all-steel Moment Frame Structural System with all-steel studs mirrors that used in our Gen7 classrooms, making River Vine a permanent structure with the same lifespan as a conventional building.

River Vine’s steel-and-concrete construction looks and performs like a high-rise building—safer, more sustainable and fully recyclable. No wood is used, making the structure resistant to fire, mold and pests.

With the roof in place, the Central Tower is the tallest part of the building—nearly 20’ tall, twice the height of the typical modular structure. Concrete floors will be poured onsite to reduce shipping weight.

The Tower roofline has both functional and architectural elements. The frame is built to hold upper clerestory windows that will automatically open and close for natural ventilation and daylighting.

Roofing fabrication starts with the Central Tower, the most complex part of River Vine’s design. The Tower’s elevated roofline is custom-fabricated by our skilled in-house crew.

The first modules have floors in place. The flexible reinforcement of the steel decking, combined with the compressive strength of the concrete, gives River Vine’s flooring system greater structural support.

Once the radiant tubing is securely fastened, our concrete contractors poured a thick 6” concrete slab on top, embedding the tubing in the floor. The concrete was leveled and left to cure.

Uponor PEX tubing is looped on top of the steel decking to provide in-floor radiant heating and cooling. Heated water will move through the tubing, providing multi-zone climate control for the entire home.

River Vine modules are built floor-up. Our flooring assembly starts with pre-cut sheets of composite steel decking from ASC Steel Deck, hand-installed to support the placement of structural concrete.
