Built in the shop. Set on site.
We design assemblies for fabrication, build them under a roof with factory checks, and deliver them to the hook the day the crew is ready to set them.
Why it matters.
Field labor is scarce
Skilled trades are hard to find in many markets. Moving repetitive work into a controlled shop gets more done with the crews you have.
Weather and height cost time
Work done on a bench at waist height, out of the rain, is faster and safer than the same work done on a lift three floors up.
Repetition rewards a system
Hundreds of identical bathrooms, corridors or wall bays should be built once as a design, then produced, not reinvented room by room.
How we work.
- 01
Design for assembly
We pick the scopes that pay off off site, then detail them in the model with connection points, tolerances and lifting points fixed before fabrication starts.
- 02
Prefabricated MEP racks
Corridor racks carrying duct, pipe, conduit and cable tray are built in modules, pressure tested in the shop and lifted into place as one piece.
- 03
Modular bathroom pods
Finished bathrooms with tile, fixtures and rough-in complete arrive wrapped and ready to connect, which takes the most trade-heavy room off the critical path.
- 04
Panelized exterior walls
Framed, sheathed and waterproofed wall panels close in the building floor by floor, so interior trades start sooner.
- 05
Factory QA and just-in-time delivery
Every unit is inspected and tagged before it ships. Deliveries are sequenced to the crane plan so units go from truck to building with little or no laydown.
What you receive.
Every engagement is scoped to the project. These are the core outputs owners can expect.
Which assemblies to build off site, why, and their cost and schedule effect against stick-built work.
Coordinated models and spool drawings with every connection, hanger and penetration located.
Inspection checklists, pressure tests and photos for each module, tied to its tag number.
A truck-by-truck schedule matched to crane picks, floor release and hoist access.
How each unit connects to building systems, with the trades and inspections needed at each tie-in.
Apartments built in a factory, set in days.
On a volumetric apartment project, every module is finished in the factory, down to the fixtures, from the coordination model. The factory production schedule and the site schedule are run as one: foundations and podium are timed to the first module off the line, deliveries arrive in set order, and stitch crews follow the crane floor by floor. When the factory slips a day, the site sees it the same day.

Questions owners ask us.
Does prefabrication cost more?
Sometimes the unit price is higher. The savings come from a shorter schedule, fewer field labor hours and less rework. We price both ways so you can see the full picture.
When do we need to decide on prefabrication?
Early in design. Module sizes, shaft locations and floor-to-floor heights all shape what can be built off site, and they are hard to change later.
What happens if a module is damaged in transit?
Units ship wrapped and braced, and each is inspected on arrival before it is set. Our delivery plan holds spare capacity in the shop so a replacement does not stop the floor.
Can prefabrication work on a renovation?
Yes. MEP racks, headwalls and other assemblies are often the fastest way to work inside an occupied building, because less work happens in the space.
