Offsite Construction Jobs: What the Work Is and How to Train for It
Module Building Systems

Offsite construction jobs are roles that build a home's walls, floors and roofs in a factory, from running a CNC saw to setting panels on a foundation. At Module Building Systems (MBS), those jobs start at our North St. Louis plant, and we train for them with Ranken Technical College and SLATE, the St. Louis Agency on Training and Employment.
Contractors need the people. In the 2026 workforce survey from the Associated General Contractors of America and NCCER, 87% of respondents reported openings for hourly craft positions, and half said available candidates lack needed skills, certificates or licenses (AGC, Sept. 3, 2026).
That second number is the one we watch. The gap is training. A factory is a good place to close it.
What are offsite construction jobs?
Offsite construction jobs are the roles that turn a set of drawings into building parts in a factory, then put those parts together on site. Offsite construction means building parts of a building in a plant and shipping them to the job for assembly. In panelized construction, those parts are wall, floor and roof panels made of conventional wood framing, and the work splits three ways.
On the factory floor
Our line runs in six stops, and every stop is a job. The CNC crosscut saw, the yellow and blue machine, cuts studs, plates and header stock to length from a digital cut list. The CNC subcomponent nailer builds headers, king and jack assemblies and stud packs. The multi-bridge nails sheathing to the project's fastening schedule and routes the window and door openings. Then comes the line, where the exterior membrane goes on, followed by the tilt transfer station for insulation and the MEP racks, where windows, MEP rough-ins and cladding go in when a package specifies them. Inspection happens on the line, before a panel loads out.

In design and planning
Before a board is cut, someone turns the plans into a model. CAD and BIM drafters build that model, then the assembly drawings and the CNC shop drawings the machines read. Estimators price the job from permit-ready plans. Production schedulers plan the build so trucks leave loaded in the order a crew will set the panels.
In the field
Panels still need people on site. Crews set them, often with a crane, then brace and connect them while drivers and logistics staff keep the loads coming in set order. On our jobs, the general contractor or the framer's crew sets the panels, and our own crew installs when the agreement calls for it.

Can you get an offsite construction job with no experience?
Many entry roles on a panel line are learned on the job, one station at a time. The saw runs from a cut list. The nailer follows a configured pattern. What a new hire needs on day one is the basics: reading a tape and a drawing, working safely around machines, and showing up ready to learn.
Training shortens the climb. An OSHA 10 card, an NCCER credential or a technical college program puts a candidate ahead, and in St. Louis the city's own workforce agency offers its services at no cost.
The skills travel, too. Someone who learned header build-ups and king and jack assemblies at our subcomponent nailer reads a framing plan the same way a field carpenter does. That makes a plant job a first step into the trades, with a path to the field or to a lead role on the line.
Where can you train for offsite construction jobs in St. Louis?
In St. Louis, the main training paths run through Ranken Technical College, SLATE and employers who train on their own floors, like us. We partner with Ranken and SLATE.
Ranken's St. Louis campus has run in the same location for more than a century. Through our partnership, Ranken students get hands-on time with our technology and processes on actual panelized and manufacturing work, outside the classroom.
SLATE is the City of St. Louis agency that offers job seekers and businesses no-cost employment services, and it has served the city since 1975. We partner with SLATE as a workforce training provider, with a focus on residents of North St. Louis.
The newest piece is YouthBuild. In July, SLATE won a $1,285,628 YouthBuild grant from the U.S. Department of Labor to serve 60 young people ages 16 to 24 from the city and nearby communities. In partnership with Ranken, participants earn industry-recognized construction credentials through NCCER (City of St. Louis, July 23, 2026). That is the pipeline a plant needs: people who arrive with safety training and a credential, then learn the machines.

Why panelized construction careers start indoors
Panelized construction careers start indoors because most of the framing moves into a plant, where the work runs year-round and out of the weather. A stud cut in January is cut the same way as one cut in July. The stations repeat, so a new hire practices the same task many times each day.
There is room to grow. Of the 975,000 single-family homes completed in 2025, about 30,000 were modular or panelized, a 3% share that matched 2023 and 2024, NAHB reports from Census data. In the Midwest the share was 5% (NAHB Eye on Housing, Oct. 21, 2026). Every point of share the industry gains needs trained people on a line.
Where the plant sits matters as much. Ours is at 921 N 20th Street in North St. Louis by choice. Our mission rests on three pillars, social, environmental and educational, and hiring and training locally serves all three. It ties to our homes in The Ville, too. We are building them for the city's infill program, a story that made the Post-Dispatch front page, on lots like the ones in our guide to vacant lots in North St. Louis.
For builders, the same worker gap shows up as missed schedules. We covered that side in The Construction Labor Shortage Needs a Better Way to Build.

Frequently asked questions
What jobs are available in offsite construction?
Offsite construction jobs cover the factory, the design office and the field. In a panel plant that means CNC machine operators, panel assemblers, quality control and production scheduling. Design roles include CAD and BIM drafting, shop drawings and estimating. Field roles cover panel setting, on-site assembly, transportation and site safety. A framing skill learned in the plant carries into the field.
Do you need construction experience to work in a panel plant?
Not always. Many plant roles are learned station by station, with the machines working from drawings and cut lists. What helps most on day one is basic safety training such as OSHA 10, comfort reading a tape measure and a drawing, and steady attendance. A technical college program or an NCCER credential shortens the learning curve and opens more roles.
Does offsite construction take jobs away from field crews?
It moves part of the framing indoors, and the field still needs crews. Panels arrive in the order the crew will set them, and crews on site set, brace and connect them, then finish the building. At MBS, the general contractor's or framer's crew sets our panels unless we install by agreement. Factory framing makes a crew faster on site. It does not replace the crew.
Where can I find free construction training in St. Louis?
Start with SLATE, the St. Louis Agency on Training and Employment. It is the City of St. Louis agency that offers job seekers no-cost employment services, and its YouthBuild program trains young people for NCCER construction credentials in partnership with Ranken Technical College. Ranken also runs its own technical programs. MBS partners with both SLATE and Ranken.
Can students or workforce groups tour the MBS plant?
Yes. We run factory tours Monday to Friday at 921 N 20th Street in North St. Louis, and we welcome students, teachers, workforce boards and crews. A tour walks the line in order, from the CNC crosscut saw to the MEP racks, so visitors see each job up close. Book through our factory tour page.
