Scope of this guide. Published costs, savings and schedules are indicative examples, not a project quotation or guarantee. Compare the same location, specification and scope. Structural supply, civil works, building services, finishes and logistics must be confirmed separately; permit and engineering requirements depend on the site.
In short
- SmartBrix Construction delivers permanent steel-framed buildings typically in 3–5 months from foundations, and finished modular projects in 60–120 days.
- Steel framing is a structural system of cold-formed steel members; modular construction prefabricates complete spaces with MEP systems pre-integrated.
- Modules can be dismantled and relocated, while a steel-framed building stays on its site and expands in stages.
- Both systems are designed to NSR-10, REP-2021, or the IBC, depending on the project’s jurisdiction.
- SmartBrix combines them when part of a program is permanent and part is urgent or temporary, as in healthcare.
SmartBrix Construction builds with two systems. Cold-formed steel (CFS) framing is its primary line for buildings that stay on their site, typically delivered in 3–5 months from foundations. Modular construction is its rapid-deployment line: the finished project is delivered in 60–120 days, and the modules can be dismantled and relocated. The right choice depends on permanence, use, site access, and schedule.
The two systems are not the same, and SmartBrix combines them when a program has permanent parts and urgent parts. This guide defines both, compares them side by side, shows which system SmartBrix uses in each sector, and ends with five questions to help you decide.
What each system is
Steel framing, or cold-formed steel (CFS) framing, also called light-gauge steel (LGS), is a building system of cold-formed steel members with a Zn-Al-Mg coating. The members are dry-assembled into load-bearing walls, floor systems, and roof trusses. When the members are fabricated at the group’s CNC plant, operated by NewCon Steel®, they arrive on site cut, punched, and labeled to a ±0.5 mm (±0.02 in) fabrication tolerance.
Prefabricated modular construction is an industrialized system in which spaces are built at the plant as complete modules (structure, enclosure, finishes, and building systems) and arrive on site ready for dry assembly. In US terms, this is volumetric modular construction. SmartBrix works with interconnectable modules, which couple together into classrooms, offices, or health posts (small clinics), and with flat-pack modules, which ship disassembled in flat packs, sized for shipping containers.
The core difference is what gets prefabricated. Steel framing is a structural system: the plant fabricates the framing members, and MEP systems, cladding, and finishes are completed on site. Modular construction is a way to prefabricate and organize the spaces themselves: each module leaves the plant with most of that work done. A modular project can use a steel structure, but the system and the level of finish are specified separately, as the SmartBrix FAQ explains.
Steel framing vs. modular, side by side
Table 1. Figures and features that SmartBrix Construction publishes for each line. Each project’s schedule depends on its scope.
| Criterion | Steel framing | Modular construction |
|---|---|---|
| Role at SmartBrix | Primary line | Secondary, rapid-deployment line |
| Published schedule | Typically 3–5 months from foundations | Finished project in 60–120 days |
| Versus traditional construction | Up to 90% faster | Up to 90% faster |
| Permanence | Permanent buildings | Temporary or permanent spaces, depending on design |
| Relocation | Stays on its site and expands in stages | Modules are dismantled, moved, and reinstalled |
| What leaves the plant | Members CNC-cut, punched, and labeled | Complete modules with MEP systems pre-integrated |
| MEP systems | Installed on site (plumbing and electrical rough-in; RETIE in Colombia) | Pre-integrated; only connected on site |
| Foundations | Foundations and slab, designed for a structure lighter than a concrete one | Leveled pier footings under each module |
| Waste vs. traditional construction | Up to 30% less | Up to 30% less |
| Typical uses | Industrial buildings and warehouses, schools and universities, hospitals, corporate offices, and housing | Camps, temporary classrooms and offices, health posts, and modular warehouses |
The two schedule figures are not measured the same way: the steel framing figure counts from the foundations, while the modular figure refers to the finished project. To see which is faster for you, ask for both schedules with the same start date and the same scope.
The eight-step process for each system
Table 2. The sequence SmartBrix publishes for each line.
| Step | Steel framing | Modular construction |
|---|---|---|
| 1 | Design: structural engineering and BIM modeling (Revit / IFC) | Leveled pier footings under each module |
| 2 | Fabrication of CNC-cut LGS members | Erection of each module’s steel structure |
| 3 | Foundations and slab pour | Lifting and setting modules on the footings |
| 4 | Dry erection of walls and trusses | Exterior finishes: enclosure and building envelope |
| 5 | Plumbing and electrical rough-in | Interior finishes: interior walls, floors, and ceilings |
| 6 | Exterior cladding | Panels and partitions |
| 7 | Sheathing and structural panels to close in the building | Connection and testing of electrical systems |
| 8 | Interior finishes and bathroom fixtures | Connection of plumbing lines and fixtures |
The modular sequence covers the work on site. The modules are fabricated at the plant while sitework advances on the lot, so the site sees less wet work than a conventional build.
Which system SmartBrix uses in each sector
SmartBrix assigns the system by building use. These are the criteria it publishes on its sector and system pages:
Table 3. Primary system by sector, and when the other system comes in.
| Sector | Primary system | When the other system comes in |
|---|---|---|
| Industrial and logistics | Steel framing: industrial buildings and warehouses with long clear spans and no intermediate columns | Modular warehouses, when storage is temporary, changes location, or grows module by module |
| Education | Steel framing for permanent school and university buildings | Prefabricated modular classrooms that grow with enrollment and can relocate |
| Healthcare | Modular construction: modular hospitals and health posts with pre-integrated MEP systems | Steel framing for permanent, larger healthcare buildings |
| Housing | Steel framing: turnkey homes and housing projects | SmartBrix publishes no modular option for housing; future additions are built in steel framing |
| Offices and camps | Modular construction: oil, mining, and military camps, plus site offices | Steel framing for permanent corporate offices |
The seven documented builds in the SmartBrix portfolio range from 1,100 m² (about 11,800 sq ft) to 39,000 m² (about 420,000 sq ft). All are PEB Corp Group projects executed by SmartBrix Construction. In steel framing, Universidad del Rosario in Bogotá (11,500 m², about 123,800 sq ft) was delivered in 100 days. The shortest schedule in the portfolio belongs to the Hospital Modular in Panama City, built with modular construction: 2,430 m² (about 26,200 sq ft) delivered in 30 days. A reference project’s area and delivery period describe that case; they do not guarantee another building’s schedule.
Codes and design for both systems
Both systems are designed and checked to the code of the project’s jurisdiction: NSR-10 (Colombia’s seismic building code) in Colombia, REP-2021 (Panama’s structural design code) in Panama, and the IBC (International Building Code) where it applies. Electrical systems in Colombia follow RETIE. A building is not certified to a code; it is designed and verified to it, and the authority having jurisdiction (AHJ) issues the building permit.
In steel framing, members are designed to AISI S100-16 (R2020), the North American specification for cold-formed steel structural members. Hurricane design is verified per project up to 250 km/h (155 mph), Saffir-Simpson Category 4. The quoted wind speed is a design reference, not a universal building rating. That published verification applies to the steel framing line; on a modular project, wind criteria are set in each site’s design.
For a coastal or high-wind site, ask for the same documents under either system: site-specific design criteria, anchorage and connection details, coating specifications, envelope requirements, and a maintenance plan. A building’s resistance depends on the complete system and its design; it cannot be inferred from the material alone or from a wind speed published for another project.
When to combine steel framing and modular
The two systems work together in one program when part of the project is permanent and part is urgent, temporary, or mobile. SmartBrix states it this way for healthcare: for permanent, larger healthcare buildings, steel framing complements the modular line. The same logic applies to other uses:
- Healthcare: health posts or modules to add capacity in weeks, and a permanent steel-framed building for the long-term facility.
- Education: a permanent steel-framed building, plus modular classrooms that absorb extra enrollment and relocate when demand shifts.
- Industrial: the main building in steel framing, plus modular warehouses for temporary storage that moves with the operation.
Steel framing also comes in degrees of prefabrication. NewCon Steel supplies the steel as loose members that are framed on site, or as pre-assembled structural panels (walls, floor cassettes, and trusses) that arrive numbered and reduce framing work on site. In US terms, that is the difference between stick-built and panelized framing. The choice moves more work into the plant without changing the building’s structural system.
For more depth, PEB Corp publishes a technical guide to LGS steel framing and a comparison of industrialized and traditional construction.
Five questions to decide
- How long will the building stay on this site? If it is permanent and larger in scale, SmartBrix’s primary line is steel framing. If it is temporary or may move, evaluate modular.
- Will you need to move or reuse it? Modules are dismantled, moved, and used again on another site. A steel-framed building expands in stages on the same site.
- Which date drives the project? Compare complete schedules with the same start date, not each system’s headline figure.
- How do you reach the site? For remote sites, container-sized flat-pack modules simplify transport. On urban lots, check the space available for unloading and crane lifts.
- How repetitive are the spaces, and what spans do you need? Repeated rooms such as dormitories, classrooms, or exam rooms suit modules. Open floors with long clear spans are handled with steel framing trusses.
If you are still unsure, send the use, area, location, and target date, and SmartBrix will propose the system, or the combination, with the scope of each option.
