This page presents reference exploration of plan interpretation, steel frame logic, BIM-ready data, model checks, kit organization, logistics planning, and cost modeling. The materials support workflow study only.
Real Field Evidence
Steel frame, wall, BIM, kit, and cost logic use field-verifiable assembly examples as reference for review.
This is a public R&D update. Final structure, code compliance, pricing, permits, logistics, and installation work requires project-specific professional review.
K&K R&D maintains reference work on a modular housing workflow. The materials connect plan interpretation, structural logic, wall and MEP planning, BIM-ready data, model checks, container loading, field reassembly planning, and cost modeling for review.
This update documents a workflow study, not a completed design or offered building system. Any project would require its own engineering, code, pricing, logistics, and installation review.
Review Base Plan Inputs
The workflow review begins with a customer-recognized base plan. Layout, room relationships, window and door positions, heights, and major functional intent are treated as source inputs. This preserves original design intent for further review.
In the current reference model, geometry, structure, wall systems, MEP routing assumptions, container loading logic, and cost data are connected. The model serves as a sample for workflow refinement.

Review Steel Frame Logic
High-wind applications require project-specific engineering. The workflow study organizes structure around load paths, defined openings, connection zones, and reassembly logic so those assumptions can be reviewed.
The reference workflow uses HSS main frame members for the primary load path, C/U type secondary framing for walls, floors, and roof support, reinforced door and window openings, diaphragm-style roof and floor elements, and defined anchor and connection locations. The package is shaped to support factory drilling, welding, numbering, and prefit checks for field reassembly.

Organize components into installation kits
The reference workflow groups components by installation phase, structural zone, wall cassette, MEP interface, floor and roof layer, connection hardware, and access-panel area.
The approach moves some sequencing decisions into the design and factory package. In the model, steel members group by installation order, wall cassettes by sets, fasteners by node, MEP interfaces in service zones, finish and access panels separate from structural items, and floor/roof layers loose-packed where transport risk is lower.
Review Lightweight BIM Data and Model Checks
The R&D center maintains a machine-readable inspection package for the reference model. Data includes component IDs, bounding boxes, centerlines, component types, system ownership, connection nodes, allowed overlaps, access areas, and container-loading context.
The model supports review by people and by software. Checks under test include collision review, floating wall conditions, duplicated wall logic, door and window conflicts, MEP route chase alignment, access panel coverage, node reachability, fastener intrusion into finish areas, and load dimensions for 40HQ container logic.

Review Wall, Insulation, Finish, and MEP Configurations
The current base configuration studies an Economy+ direction. It uses MgO board as substrate or structural sheathing, interior PVC/WPC/wood-look finish panels, rock wool for insulation and acoustic control, metal exterior finish over WRB and MgO layers, and a roof terrace direction using TPO waterproofing with removable WPC deck boards.
In the reference, MEP rough-in keeps key interfaces serviceable and access areas protected. Factory-suitable work is assigned to the factory while access for inspection, testing, and maintenance is preserved.

Review Cost Modeling for Early Planning
The R&D workflow tests structured cost modeling so early budget direction does not rely on a single guessed total. Cost items can be tied to quantity source, price source, inclusions, exclusions, dependencies, and risk sensitivity.
For the reference model, internal figures cover factory goods and services, ocean freight, U.S. installation labor, and tariff sensitivity. These are not public fixed quotes and exclude project-specific foundation, permit, site access, utility, engineering, or jurisdictional items. The figures help assess whether a budget direction is plausible before deeper quote and engineering work.
Review Factory Planning and Reassembly Logic
The reference workflow organizes steel receiving, cutting, drilling, welding, test fitting, numbering, wall-cassette production, MEP preassembly, packing, photo records, and loading assumptions into a sequence that can be reviewed before field work.
Further development of this workflow may support additional layouts, configuration levels, supplier feedback, engineering review, installation feedback, and process refinement.
Review the Current R&D Foundation
The work is a development foundation under study: plan interpretation, steel structure logic, lightweight BIM, inspection routines, stage-ready kit planning, factory PM organization, cost modeling, supplier quote evidence, customer budget state logic, and review packages for designers and engineers.
